Description

本発明は、ＬＥＤ（発光ダイオード）のような発光素子を光源に使用した照明灯（ランプ）に関するものである。   The present invention relates to an illuminating lamp (lamp) using a light emitting element such as an LED (light emitting diode) as a light source.

発光素子の代表例であるＬＥＤ（発光ダイオード）は白熱電球や蛍光灯に比べて消費電力が少なく耐久性にも優れており、しかも多用な色彩を実現できる特徴がある。そこで、近年、ＬＥＤを使用した照明灯が多数提案されている。例えば、特許文献１及び２などに、従来の蛍光灯の代替品として蛍光灯器具のソケット部に接続して使用できるＬＥＤ式照明灯が記載されている。特許文献１及び２ではいずれも、細長い円筒パイプ（カバー）の内側に、長手方向に沿ってＬＥＤが複数実装された１枚の細長い基板を配置している。   An LED (light emitting diode), which is a typical example of a light emitting element, has lower power consumption and superior durability than incandescent bulbs and fluorescent lamps, and is characterized by being able to realize a variety of colors. In recent years, therefore, many illuminating lamps using LEDs have been proposed. For example, Patent Documents 1 and 2 describe an LED illumination lamp that can be used by connecting to a socket portion of a fluorescent lamp fixture as an alternative to a conventional fluorescent lamp. In both Patent Documents 1 and 2, one elongated substrate on which a plurality of LEDs are mounted along the longitudinal direction is disposed inside the elongated cylindrical pipe (cover).

そして、特許文献１では、基板の両端部に通電用端子が２本ずつ設けられている一方、円筒パイプの両端部にはベースキャップが嵌め込まれており、ベースキャップから前記端子の先端を外方側に突出させて蛍光灯器具のソケット部に差し込むように構成されている。   And in patent document 1, while two terminals for electricity supply are provided in the both ends of a board | substrate, the base cap is engage | inserted in the both ends of a cylindrical pipe, and the front-end | tip of the said terminal is outward from a base cap. It protrudes to the side and is configured to be inserted into the socket part of the fluorescent lamp fixture.

他方、特許文献２では、円筒パイプの内周部に、長手方向に適宜間隔をあけた状態で複数の樹脂製クリップが配置されている。詳細な説明はないが、図面には、基板の長手方向の両端近傍と中央の計３箇所にクリップを配置して、各クリップの先端部を基板に貫通して（差し込んで）、クリップを介して基板を円筒パイプで支持した状態が示されている。   On the other hand, in Patent Document 2, a plurality of resin clips are arranged on the inner peripheral portion of the cylindrical pipe with appropriate intervals in the longitudinal direction. Although there is no detailed explanation, in the drawing, clips are arranged at a total of three locations in the vicinity of the both ends in the longitudinal direction of the substrate and in the center, and the leading end of each clip is penetrated (inserted) into the substrate, and the clips are inserted. The substrate is supported by a cylindrical pipe.

特開２００１−３５１４０２号公報（特に図３，図６）Japanese Patent Laid-Open No. 2001-351402 (particularly FIGS. 3 and 6) 特開２００７−１２３２２号公報（特に図１，図３）JP 2007-12322 A (particularly FIGS. 1 and 3)

蛍光灯に代替する照明灯では、ＬＥＤを装着した基板が細長い円筒パイプに合わせて細長い帯板状（長尺）に形成されているため、特許文献１，２のように基板の長手方向の両端や中央を支持するだけでは、支持部間の間隔が長くなるため基板を安定的に支持し難い。そのため、照明灯の輸送時に設置後の使用時に外力（落下による衝撃や地震の発生など）を受けると基板に大きな撓みが発生し、ひどい場合には導線（或いは配線パターン）の断線や基板の破損等の不具合が発生する虞がある。   In an illuminating lamp that replaces a fluorescent lamp, the substrate on which the LED is mounted is formed in an elongated strip shape (long) in accordance with an elongated cylindrical pipe. In addition, it is difficult to stably support the substrate because the distance between the support portions becomes long simply by supporting the center. Therefore, if the external force (such as an impact or an earthquake due to a drop) is received during installation after the lighting lamp is transported, the board will be greatly bent, and if it is severe, the conductor (or wiring pattern) may be broken or the board may be damaged. There is a risk of problems such as these.

この点については、特許文献２に記載されているクリップの数を増やして、基板をその長手方向に沿って多数箇所で支持すれば良いと考えられる。しかしながら、細長い円筒パイプの端部からその内部に長尺の基板を挿入した後に、円筒パイプの端部から離れた狭い空間においてＬＥＤを傷付けないようにしながら基板をクリップに嵌め込む作業は極めて厄介であり、組み立て作業に多大の手間がかかるという問題がある。   Regarding this point, it is considered that the number of clips described in Patent Document 2 may be increased to support the substrate at a number of locations along the longitudinal direction. However, after inserting a long substrate into the inside of the end of the elongated cylindrical pipe, it is extremely troublesome to fit the substrate into the clip while preventing the LED from being damaged in a narrow space away from the end of the cylindrical pipe. There is a problem that the assembly work takes much time.

本発明は、このような現状を改善することを主たる目的として成されたものである。さて、ＬＥＤは点光源であるため、蛍光灯方式の細長い照明灯に適用するとＬＥＤがポツポツと見えて人に違和感を与える問題がある。本願発明者たちは、上記現状の改善を端緒としつつ違和感のない照明のような幾つかの改良も成しており、これらの改良も明細書及び図面で開示している。   The present invention has been made mainly for the purpose of improving such a current situation. Now, since the LED is a point light source, there is a problem in that when the LED is applied to a fluorescent lamp-type long and narrow illumination lamp, the LED looks poppy and gives a strange feeling to a person. The inventors of the present application have also made some improvements such as lighting without any sense of incongruity starting from the above improvement of the present situation, and these improvements are also disclosed in the specification and drawings.

本願発明は請求項１〜６として特定されている。このうち請求項１の発明に係る照明灯は、まず、基本構成として、一体で長く延びるか又は断続して長く延びる基板と、前記基板の片面又は両面に設けた発光素子と、前記基板を少なくとも発光素子の側から覆う筒形又は溝形の細長いカバー部材（カバー手段）とを備えている。   The present invention is specified as claims 1-6. Among these, the illuminating lamp according to the invention of claim 1 has, as a basic configuration, at least a substrate integrally extending long or intermittently extending, a light emitting element provided on one or both sides of the substrate, and at least the substrate. And a cylindrical or groove-shaped elongated cover member (cover means) covering from the light emitting element side.

そして、前記カバー部材は成形品であって、前記発光素子の光が透過するように少なくとも一部は透光性を有しており、且つ、前記カバー部材の内面部に、前記基板の長手両側縁が直接に嵌まり込む嵌合部を長手方向に沿って延びるように形成しているか、又は、前記基板を保持した保持部材の長手側縁が嵌まり込む嵌合部を長手方向に沿って延びるように形成しており、前記嵌合部により、前記基板がその幅方向と厚さ方向とにずれ不能に保持されている。この場合、嵌合部は一連に延びていても良いし、飛び飛びに断続的に延びていてもよい。   The cover member is a molded product, and at least part of the cover member has a light-transmitting property so that light from the light-emitting element can pass therethrough. The fitting part into which the edge fits directly is formed so as to extend along the longitudinal direction, or the fitting part into which the longitudinal side edge of the holding member holding the substrate fits along the longitudinal direction. The board is formed so as to extend in the width direction and the thickness direction so as not to be displaced by the fitting portion. In this case, the fitting portion may extend in series, or may intermittently extend.

請求項２の発明は請求項１を好適に具体化したものであり、この発明では、請求項１において、前記カバー部材と前記基板との間には、前記発光素子の光を拡散させる拡散部か又は光を反射させる反射体が設けられている。この場合、拡散部はカバー部材と一体であっても別体であってもよい。また、拡散部と反射体とは少なくとも一方が備えられておればよい。   According to a second aspect of the present invention, the first aspect of the present invention is preferably embodied. In the first aspect of the present invention, the light diffusion element for diffusing light of the light emitting element is provided between the cover member and the substrate. Alternatively, a reflector that reflects light is provided. In this case, the diffusion portion may be integrated with the cover member or may be a separate body. Further, it is sufficient that at least one of the diffusing portion and the reflector is provided.

請求項３に記載の発明は請求項１又は２を具体化したものであり、この発明では、前記カバー部材は合成樹脂の押し出し成形品であって実質的に直線状に延びており、前記嵌合部は、前記カバー部材の長手方向の一端から他端まで延びる嵌合溝になっている。   A third aspect of the present invention is an embodiment of the first or second aspect. In the present invention, the cover member is an extruded product of a synthetic resin, and extends substantially linearly. The joint portion is a fitting groove extending from one end to the other end in the longitudinal direction of the cover member.

請求項４の発明も請求項１又は２を具体化したものであり、請求項１，２において、前記カバー部材は、前記基板を一方の面の側から覆う第１カバー体と他方の面の側から覆う第２カバー体とを重ねることで構成されており、前記第１カバー体と第２カバー体とが重なり合う部分に前記嵌合部が形成されている。   The invention of claim 4 also embodies claim 1 or 2, and in claim 1, the cover member comprises a first cover body that covers the substrate from one surface side and the other surface. The second cover body that covers from the side is overlapped, and the fitting portion is formed at a portion where the first cover body and the second cover body overlap.

請求項５の発明は、請求項１〜４とは別のアプローチで成されている。すなわちこの発明は、一端面と他端面とを有する細長い形状で且つ端面に入射した光が内部で方向を変えて外周面のうちの周方向の一部又は全部から出射する透光材製の導光体と、前記導光体の一端面と他端面とにそれぞれ固定（配置）されたエンド部材とを備えており、前記両エンド部材のうちのいずれか一方又は両方に、前記導光体に光を照射する発光素子を設けている。   The invention of claim 5 is made by an approach different from those of claims 1 to 4. In other words, the present invention is an elongated shape having one end surface and the other end surface, and the light incident on the end surface changes its direction and emits from a part or all of the circumferential direction of the outer peripheral surface. A light body, and end members fixed (arranged) to one end surface and the other end surface of the light guide, respectively, and one or both of the end members are connected to the light guide. A light-emitting element that emits light is provided.

請求項１に記載の発明では、基板又は保持部材の長手両側縁がカバー部材の嵌合部に嵌まり込むことにより、基板が細長い形態であっても基板を広い範囲でカバー部材で支持されるため、基板は撓みを防止又は抑制した状態に保持される。従って、運搬中や使用状態に外力が加わっても、基板が破損したり導線が断線したりする不具合を防止又は著しく抑制できる。   According to the first aspect of the present invention, the both longitudinal edges of the substrate or the holding member are fitted into the fitting portions of the cover member, so that the substrate is supported by the cover member in a wide range even if the substrate is in an elongated shape. Therefore, the substrate is held in a state in which bending is prevented or suppressed. Therefore, even when an external force is applied during transportation or in use, it is possible to prevent or remarkably suppress a problem that the substrate is damaged or the conductive wire is disconnected.

また、カバー部材は成形品であって、嵌合部を設けた状態で製造することができるので、嵌合部を設けるための加工を別途カバー部材に施す必要はなく、製造コストの削減を図ることができる。   Further, since the cover member is a molded product and can be manufactured with the fitting portion provided, it is not necessary to separately process the cover member to provide the fitting portion, thereby reducing the manufacturing cost. be able to.

請求項２の発明によると、発光素子が点光源状になっていても、拡散部を透過させるか又は反射体で乱反射させることにより、各発光素子の光を散乱させてカバー部材の透光面全体にわたって面発光させることができる。その結果、光源の存在が視認できない違和感のない照明状態を実現して、従来の蛍光灯の代替品としての使用を促進できる。   According to the invention of claim 2, even if the light emitting element is in the form of a point light source, the light from each light emitting element is scattered by being transmitted through the diffusing part or diffusely reflected by the reflector, thereby transmitting the light transmitting surface of the cover member. Surface light can be emitted throughout. As a result, an uncomfortable lighting state in which the presence of the light source cannot be visually recognized is realized, and the use as a substitute for the conventional fluorescent lamp can be promoted.

この場合、拡散部がカバー部材に一体で設けられていると、拡散部を部材として管理する手間が不要になるうえに、組み立てコストの削減を図ることができる利点がある。他方、拡散部がカバー部材に別体で設けられていると、カバー部材の材料や成形方法に制限されることなく、拡散部として最適な材料や製造方法を選択することができる。   In this case, if the diffusing portion is provided integrally with the cover member, there is an advantage that it is not necessary to manage the diffusing portion as a member, and the assembly cost can be reduced. On the other hand, when the diffusing portion is provided separately on the cover member, an optimal material and manufacturing method for the diffusing portion can be selected without being limited by the material and molding method of the cover member.

請求項３に記載の発明によれば、カバー部材が押し出し成形で製造されるから、カバー部材を直線状に形成することが容易であるうえに、カバー部材の全長にわたって嵌合溝を形成することが簡単に形成できる。そして、請求項１では嵌合部は飛び飛びに形成することも可能であるが、請求項３では嵌合溝はカバー部材の全長にわたって形成できるため、基板の支持安定性を格段に向上できる。   According to the invention described in claim 3, since the cover member is manufactured by extrusion molding, it is easy to form the cover member in a straight line, and the fitting groove is formed over the entire length of the cover member. Can be easily formed. In the first aspect, the fitting portion can be formed in a jumping manner. In the third aspect, since the fitting groove can be formed over the entire length of the cover member, the support stability of the substrate can be remarkably improved.

また、カバー部材は押し出し成形品であるから、カバー部材の何倍もの長さの中間品を製造してこれを所望の長さに切断することでカバー部材を容易に大量生産できるため、製造コストの削減を図ることも可能である。更に、中間品は任意の長さに切断できるため、カバー部材の長さが異なる照明灯を複数種類製造する場合に、コスト低減の効果が強く発揮される。   In addition, since the cover member is an extrusion molded product, it is possible to easily mass-produce the cover member by manufacturing an intermediate product that is many times longer than the cover member and cutting it into a desired length, so that the manufacturing cost It is also possible to reduce this. Furthermore, since the intermediate product can be cut to an arbitrary length, the cost reduction effect is strongly exerted when a plurality of types of illumination lamps having different cover member lengths are manufactured.

更に、嵌合溝はカバー部材の長手方向の一端から他端まで延びているから、カバー部材に基板を取り付ける作業は、嵌合溝にその一端又は他端から基板を差し込むという極めて簡単な操作で足り、従って、カバー部材と基板がともに長くても照明灯の組み立てを極めて簡単に行うことができる。   Furthermore, since the fitting groove extends from one end to the other end in the longitudinal direction of the cover member, the work of attaching the substrate to the cover member is an extremely simple operation of inserting the substrate into the fitting groove from one end or the other end. Therefore, the assembly of the illumination lamp can be performed very easily even if the cover member and the substrate are both long.

請求項４に記載の発明によれば、カバー部材は、基板を一方の面の側から覆う第１カバー体と、基板を他方の面の側から覆う第２カバー体とを重ねることで構成されているから、カバー部材が直線状の場合だけでなく、円環状等の非直線タイプであっても形成することが可能となる。また、第１及び第２カバー体の重なり合う部分に嵌合部が形成されているから、第１及び第２カバー体を重ね合わせる時に、基板を挟み込んで取り付けることができ、基板の取り付け作業も簡単で且つ安定して基板を保持できる。   According to invention of Claim 4, a cover member is comprised by overlapping the 1st cover body which covers a board | substrate from the one surface side, and the 2nd cover body which covers a board | substrate from the other surface side. Therefore, the cover member can be formed not only in the case of a linear shape but also in a non-linear type such as an annular shape. In addition, since the fitting portion is formed in the overlapping portion of the first and second cover bodies, when the first and second cover bodies are overlapped, the board can be sandwiched and attached, and the board can be easily attached. And can stably hold the substrate.

なお、請求項４の発明では、第１カバー体と第２カバー体との素材や色、透明度等の特性を変えることも可能であり、これによって多彩なデザインを実現し得る。   In the invention according to claim 4, it is also possible to change the characteristics such as the material, color, transparency and the like of the first cover body and the second cover body, and thereby various designs can be realized.

請求項５に記載の発明では、発光素子を導光体の端面部に配置したものでありながら、発光素子の光は、細長い形状の導光体の内部で方向が変わって、導光体の外周面のうちの周方向の一部又は全部から外に向かって出射し、細長い導光体の外周面を面発光させることができる。   In the invention according to claim 5, although the light emitting element is arranged on the end face portion of the light guide, the direction of the light of the light emitting element is changed inside the elongated light guide. Light can be emitted from a part or all of the outer circumferential surface in the circumferential direction to emit light from the outer circumferential surface of the elongated light guide.

そして、発光素子は導光体の端面のエンド部材に配置されているに過ぎないから、導光体（照明灯が）が細長くても、発光素子を導光体の端面の箇所に強固に保持することができるうえに、取り付け作業も容易に行うことができる。従って、強度に優れると共に組み立ても容易な発光素子方式の照明灯を蛍光灯に類似した外観として提供することができる。   Since the light emitting element is merely disposed on the end member of the end face of the light guide, the light emitting element is firmly held at the end face of the light guide even if the light guide (illumination lamp) is elongated. In addition, it can be easily attached. Therefore, it is possible to provide a light-emitting element type illumination lamp that is excellent in strength and easy to assemble with an appearance similar to a fluorescent lamp.

本実施形態に係る照明灯１は、天井面や壁面などに設置される照明装置２のランプとして使用されており、全体として細長い形態になっている（便宜的に、長手方向をＸ軸方向として説明する。）。 (1). First embodiment (FIGS. 1 to 3)
An illuminating lamp 1 according to the present embodiment is used as a lamp of an illuminating device 2 installed on a ceiling surface, a wall surface, or the like, and has an elongated shape as a whole (for convenience, the longitudinal direction is taken as the X-axis direction). explain.).

照明装置２には照明灯１を取り付けるための一対のソケット部３，４が設けられていて、照明灯１は両ソケット部３，４で脱落不能に保持される。図１（ａ）に示すように、一方のソケット部３は、照明装置２の基部２ａ側を基端（回動支点）として他方のソケット部４に対して近接離反する方向に回動可能に設けられているのに対して、他方のソケット部４は基部２ａに固定されている。従って、一方のソケット部３を他方のソケット部４から離れる方向に回動させて、照明灯１の長手方向の一端を他方のソケット部４に嵌め込み、その後、一方のソケット部３を他方のソケット部４に近づける方向に戻しながら照明灯１の他端に嵌め込むことで、照明装置２への照明灯１の取り付けが行われる。   The illuminating device 2 is provided with a pair of socket parts 3 and 4 for attaching the illuminating lamp 1, and the illuminating lamp 1 is held by the socket parts 3 and 4 so as not to fall off. As shown in FIG. 1 (a), one socket 3 is rotatable in the direction of approaching and separating from the other socket 4 with the base 2a side of the lighting device 2 as a base end (rotation fulcrum). The other socket part 4 is being fixed to the base 2a with respect to being provided. Therefore, one socket part 3 is rotated in the direction away from the other socket part 4, and one end in the longitudinal direction of the illuminating lamp 1 is fitted into the other socket part 4, and then the one socket part 3 is inserted into the other socket part. The illuminating lamp 1 is attached to the illuminating device 2 by fitting into the other end of the illuminating lamp 1 while returning to the direction close to the portion 4.

なお、図１（ａ）では、照明装置２の基部２ａに対して照明灯１が上方に位置した状態を図示しているが、天井等に照明装置２を設置する場合には上下が逆になるし、壁面に設置する場合には縦長の姿勢になる。   1A shows a state in which the illuminating lamp 1 is positioned above the base 2a of the illuminating device 2, but when the illuminating device 2 is installed on the ceiling or the like, the upside down is reversed. In the case of installation on a wall surface, it becomes a vertically long posture.

照明灯１は、光源ユニット１３とこれを覆うカバー部材１０とを備えている。光源ユニット１３は、帯状の１枚の回路基板１１の片面に発光素子としてＬＥＤ（発光ダイオード）１２を飛び飛びに複数個実装した構成になっており、これが、細長い合成樹脂製のカバー部材１０の内側に挿入されている。回路基板１１は請求項に記載した基板に相当する。   The illuminating lamp 1 includes a light source unit 13 and a cover member 10 that covers the light source unit 13. The light source unit 13 has a configuration in which a plurality of LEDs (light emitting diodes) 12 as light emitting elements are mounted on one side of a belt-like circuit board 11, and this is the inner side of an elongated synthetic resin cover member 10. Has been inserted. The circuit board 11 corresponds to the board recited in the claims.

ＬＥＤ１２は、色の三原色である赤色、緑色、青色のチップを備えた多色発光方式を採用してもよいし、白色発光ダイオードのような単色発光方式を採用してもよい。発光素子は用途に応じて適宜変更可能であり、ＬＥＤと異なる方式の発光素子（例えば有機ＥＬや半導体レーザなど）を用いることも可能である。   The LED 12 may adopt a multicolor light emission method including chips of red, green, and blue which are the three primary colors, or may adopt a single color light emission method such as a white light emitting diode. The light-emitting element can be appropriately changed depending on the application, and a light-emitting element of a different system from the LED (for example, an organic EL or a semiconductor laser) can be used.

カバー部材１０は、図１（ｂ）に示すように、長手方向から見た断面形状が下向きＵ字状（溝形，樋形、チャンネル形）に形成された主カバー体１０ａと、この主カバー体１０ａにおけるＵ字状の曲面部１５の反対側の開口部に嵌め込まれて固着（接着してもよい）された略板状の補助カバー体１０ｂとから成っており、全体としては管状を呈している。主カバー体１０ａは断面Ｕ字状であるため曲面部１５を有している。なお、主カバー体１０ａのみを請求項に記載したカバー部材の具体例と表示して、補助カバー体１０ｂはカバー部材が取り付くベース部材と称することも可能である。   As shown in FIG. 1B, the cover member 10 includes a main cover body 10a having a cross-sectional shape viewed from the longitudinal direction formed in a downward U-shape (groove shape, bowl shape, channel shape), and the main cover. It consists of a substantially plate-like auxiliary cover body 10b that is fitted and fixed (adhered) to the opening on the opposite side of the U-shaped curved surface portion 15 in the body 10a, and has a tubular shape as a whole. ing. Since the main cover body 10a has a U-shaped cross section, it has a curved surface portion 15. In addition, only the main cover body 10a is displayed as a specific example of the cover member described in the claims, and the auxiliary cover body 10b may be referred to as a base member to which the cover member is attached.

カバー部材１０の一端部は第１キャップ体１７で覆われ、他端部は第２キャップ体１８で覆われている。これらキャップ体１７，１８は各々ネジ１９で主カバー体１０ａに固定されている。主カバー体１０ａにはねじ１９をねじ込みできる長溝１９ａが全長にわたって延びている（図１（ａ），（ｂ）参照）。   One end of the cover member 10 is covered with a first cap body 17, and the other end is covered with a second cap body 18. The cap bodies 17 and 18 are each fixed to the main cover body 10a with screws 19. A long groove 19a into which the screw 19 can be screwed extends in the main cover body 10a over the entire length (see FIGS. 1A and 1B).

照明灯１を照明装置２に取り付けた状態でＬＥＤ１２が基部２ａと反対側を向くように、第１及び第２キャップ体１７，１８と両ソケット部３，４とには、互いに嵌合して方向性を規定するための凹凸が形成されている。   The first and second cap bodies 17 and 18 and the socket portions 3 and 4 are fitted to each other so that the LED 12 faces the side opposite to the base portion 2a with the illuminating lamp 1 attached to the lighting device 2. Irregularities for defining directionality are formed.

主カバー体１０ａ，補助カバー体１０ｂ，第１キャップ体１７及び第２キャップ体１８はいずれも合成樹脂製であり、主カバー体１０ａと補助カバー体１０ｂとは押し出し成形品を使用している。主カバー体１０ａはＬＥＤ１２の光が透過する必要があるので透光性を有する樹脂で製造されており、ＬＥＤ１２を外部から視認できないように乳白色が好ましい。敢えて述べるまでもないが、ＬＥＤ１２はダイオードチップを透光材で封止した構造になっている。   The main cover body 10a, auxiliary cover body 10b, first cap body 17 and second cap body 18 are all made of synthetic resin, and the main cover body 10a and auxiliary cover body 10b use extruded products. Since the main cover body 10a needs to transmit the light of the LED 12, it is made of a resin having translucency, and milky white is preferable so that the LED 12 cannot be visually recognized from the outside. Needless to say, the LED 12 has a structure in which a diode chip is sealed with a translucent material.

補助カバー体１０ｂと両キャップ体１７，１８は透光性を有しない樹脂で成形されている。もとより、これらも透光性を有する樹脂で成形してもよい。もとより、補助カバー体１０ｂと両キャップ体１７，１８とを透光性のある素材で製造することも可能である。また、補助カバー体１０ｂと両キャップ体１７，１８とは金属製とすることも可能である。補助カバー体１０ｂを金属製とする場合、加工の容易性やコストの面から押し出し成形品を使用するのが好ましい。   The auxiliary cover body 10b and the cap bodies 17 and 18 are formed of a resin that does not have translucency. Of course, these may also be formed of a translucent resin. Of course, it is also possible to manufacture the auxiliary cover body 10b and the cap bodies 17 and 18 with a translucent material. The auxiliary cover body 10b and the cap bodies 17 and 18 can be made of metal. When the auxiliary cover body 10b is made of metal, it is preferable to use an extruded product from the viewpoint of ease of processing and cost.

光源ユニット１３は、カバー部材１０よりも僅かに短い長さの細長い回路基板１１の片面に、適宜間隔をあけてＬＥＤ１２が配置された構成になっている。ＬＥＤ１２の各端子は、回路基板１１の表面又は裏面に形成されている配線パターン（図示せず）に接続されている。回路基板１１の長手方向の一端には端子２０ａを有するオス型コネクタ２０が、他端には端子２０ａが嵌まる穴を有するメス型コネクタ２１がそれぞれ取り付けられていて、ＬＥＤ１２は、前記配線パターンを介して、オス型コネクタ２０とメス型コネクタ２１とに電気的に接続される。本実施形態のＬＥＤ１２はフルカラー対応であるため、図２（ａ）に示すように、オス型コネクタ２０は４本の端子２０ａを有している。   The light source unit 13 has a configuration in which LEDs 12 are arranged on one side of an elongated circuit board 11 having a length slightly shorter than that of the cover member 10 with an appropriate interval. Each terminal of the LED 12 is connected to a wiring pattern (not shown) formed on the front surface or the back surface of the circuit board 11. A male connector 20 having a terminal 20a is attached to one end in the longitudinal direction of the circuit board 11, and a female connector 21 having a hole into which the terminal 20a is fitted is attached to the other end. The male connector 20 and the female connector 21 are electrically connected to each other. Since the LED 12 of the present embodiment is compatible with full color, the male connector 20 has four terminals 20a as shown in FIG.

オス型コネクタ２０に対応する位置の第１キャップ体１７には、オス型コネクタ２０の端子２０ａが嵌まる孔部が形成されていて、第１キャップ体１７に嵌合する一方のソケット部３とオス型コネクタ２０とが電気的に接続されている。本実施形態では、ＬＥＤ１２を発光させるための電力は一方のソケット部３及びオス型コネクタ２０側からのみ供給されるように設定しており、従って、他方のソケット部４とメス型コネクタ２１との間での電気的な接続は不要である。   The first cap body 17 at a position corresponding to the male connector 20 is formed with a hole portion into which the terminal 20a of the male connector 20 is fitted, and one socket portion 3 to be fitted into the first cap body 17; The male connector 20 is electrically connected. In the present embodiment, the power for causing the LED 12 to emit light is set to be supplied only from one socket portion 3 and the male connector 20 side. No electrical connection between them is necessary.

そのため、光源ユニット１３を１だけしか使用しない場合は、他方のソケット部４と対向する位置にあるメス型コネクタ２１は設置を省略することも可能であるが、後述するように、複数の光源ユニット１３を連結する際には、メス型コネクタ２１はオス型コネクタ２０との電気的な接続に利用される。   Therefore, when only one light source unit 13 is used, the installation of the female connector 21 located at the position facing the other socket portion 4 can be omitted. However, as will be described later, a plurality of light source units are used. When connecting 13, the female connector 21 is used for electrical connection with the male connector 20.

図１（ａ）に示すように、照明装置２にはＬＥＤ１２に電力を供給するための回路部１４を設けている。回路部１４は、ＡＣ／ＤＣ変換器や、電圧をＬＥＤに応じた値に調整する電圧制御部などを含んでいる。これら回路部１４は、照明装置２の基部２ａに内蔵しているが、小型化して、一方のソケット部３に内蔵したり回路基板１１の裏面に実装したりすることも可能である。   As shown to Fig.1 (a), the illuminating device 2 is provided with the circuit part 14 for supplying electric power to LED12. The circuit unit 14 includes an AC / DC converter, a voltage control unit that adjusts the voltage to a value corresponding to the LED, and the like. These circuit units 14 are built in the base 2 a of the lighting device 2, but they can be reduced in size and built in one socket unit 3 or mounted on the back surface of the circuit board 11.

カバー部材１０の内部のうち主カバー体１０ａの曲面部１５と光源ユニット１３との間には、ＬＥＤ１２の発光を拡散させるための拡散部の一例としてのシート状の拡散板２５が、光源ユニット１４と略同じ長さで長く延びるように配置されている。拡散板２５は、表面又は裏面もしくは表裏両面に多数の細かい凹凸が形成されていて透光性を有する樹脂製のシート状体が使用されており、カバー部材１０の軸方向から見て主カバー体１０ａの曲面部１５と同じ方向に凸となるように湾曲している。各ＬＥＤ１２から出た光は拡散板２５を通ることで拡散・散乱し、これにより、主カバー体１０ａの透光面を全体にわたって略均一に面発光させことができる。   Between the curved surface portion 15 of the main cover body 10 a and the light source unit 13 in the cover member 10, a sheet-like diffusion plate 25 as an example of a diffusion portion for diffusing the light emission of the LED 12 is provided in the light source unit 14. Are arranged so as to extend long with substantially the same length. The diffuser plate 25 is made of a resinous sheet-like body having a large number of fine irregularities formed on the front surface, back surface, or both front and back surfaces, and having translucency. The main cover body is viewed from the axial direction of the cover member 10. It is curved to be convex in the same direction as the curved surface portion 10a. The light emitted from each LED 12 is diffused and scattered by passing through the diffusion plate 25, whereby the light transmitting surface of the main cover body 10a can be surface-emitting substantially uniformly over the entire surface.

拡散板２５と回路基板１１との間には、ＬＥＤ１２の発光を拡散板２５の方へ集光及び反射させるための反射面を有するシート状の反射板２６が、拡散板２５と同様に光源ユニット１４と略同じ長さに長く延びるように配置されている。反射板２６は、図１（ｂ）及び（ｃ）に示すように、幅方向（Ｙ軸方向）の中心部が拡散板２５と離れる方向に湾曲した形状に設けられており（すなわち、軸方向から見て拡散板２５に向けて凹となるように湾曲しており）、かつ、反射板２６に設けた貫通穴２７からＬＥＤ１２の先端が曲面部１５側に突出している。反射板２６は回路基板１１に当接していても良い。なお、図１（ａ）及び（ｂ）では、拡散板２５と反射板２６のハッチングを省略している。   Between the diffusion plate 25 and the circuit board 11, a sheet-like reflection plate 26 having a reflection surface for condensing and reflecting the light emission of the LED 12 toward the diffusion plate 25 is a light source unit. 14 so as to extend substantially the same length as 14. As shown in FIGS. 1B and 1C, the reflection plate 26 is provided in a shape in which the central portion in the width direction (Y-axis direction) is curved in a direction away from the diffusion plate 25 (that is, in the axial direction). The tip of the LED 12 protrudes from the through hole 27 provided in the reflection plate 26 toward the curved surface portion 15 side. The reflector 26 may be in contact with the circuit board 11. In FIGS. 1A and 1B, hatching of the diffusion plate 25 and the reflection plate 26 is omitted.

ＬＥＤ１２の発光は、主として主カバー体１０ａの曲面部１５に向かって進むが、一部は拡散板２５を透過して一部は拡散板２５によって反射し、拡散板２５げ反射した光は反射板２６で反射して再び拡散板２５に向けて照射される。また、拡散板２５を透過した光の一部は主カバー体１０ａを透過し、他の一部は主カバー体１０ａの内面で反射して拡散板２５に向けて照射され、拡散板２５に向けて反射した光のうち一部は拡散板２５を反射し、他の一部は拡散板２５を透過する。また、光は拡散板２５と主カバー体１０ａとを透過するに際して屈折による拡散作用を受ける。   The light emission of the LED 12 proceeds mainly toward the curved surface portion 15 of the main cover body 10a, but a part of the light is transmitted through the diffusion plate 25 and is reflected by the diffusion plate 25, and the light reflected from the diffusion plate 25 is reflected by the reflection plate. The light is reflected at 26 and irradiated again toward the diffusion plate 25. A part of the light transmitted through the diffusion plate 25 is transmitted through the main cover body 10a, and the other part is reflected by the inner surface of the main cover body 10a and irradiated toward the diffusion plate 25. Part of the reflected light is reflected from the diffusion plate 25 and the other part is transmitted through the diffusion plate 25. Further, the light undergoes a diffusion action due to refraction when passing through the diffusion plate 25 and the main cover body 10a.

このように、ＬＥＤ１２から照射された光は、拡散板２５及び主カバー体１０ａによる反射及び拡散作用と反射板２６による反射拡散作用とを受けて広い範囲に散乱し、その結果、照明灯１はＬＥＤ１２の存在を全く視認できない状態に面発光した状態が実現される。また、反射板２６による反射・拡散により、ＬＥＤ１２から出た光を照明に効率よく利用できる。   As described above, the light emitted from the LED 12 is scattered over a wide range due to the reflection and diffusion action by the diffusion plate 25 and the main cover body 10a and the reflection diffusion action by the reflection plate 26. As a result, the illumination lamp 1 is A surface emitting state is realized in a state where the presence of the LED 12 cannot be visually recognized at all. Further, the light emitted from the LED 12 can be efficiently used for illumination by reflection / diffusion by the reflection plate 26.

反射板２６は、薄い金属板（例えば、アルミニウムやステンレス等の薄板）で形成されている。機能的には、少なくとも拡散板２５側の面が反射面に形成されていればよいため、樹脂フィルム等の片面に金属層を蒸着して形成したものを用いてもよい。反射手段としては、基板１１の表面に反射フィルムを貼ってもよい。樹脂の成形品を使用することも可能である。   The reflection plate 26 is formed of a thin metal plate (for example, a thin plate such as aluminum or stainless steel). Functionally, since at least the surface on the diffusion plate 25 side only needs to be formed on the reflecting surface, a metal film deposited on one surface such as a resin film may be used. As a reflecting means, a reflective film may be pasted on the surface of the substrate 11. It is also possible to use a resin molded product.

主カバー体１０ａのうち相対向した２つの側面部の内面には、回路基板１１の嵌合部の一例として、回路基板１１の長手側縁が嵌まる第１嵌合溝３１が全長にわたって（すなわちＸ軸方向に長く延びるように）形成されている。さらに、主カバー体１０ａのうち第１嵌合部３１よりも曲面部１５に近い位置に、拡散板２５及び反射板２６の長手側縁が嵌まる一対の第２嵌合溝３２が全長にわたって形成されている。第２嵌合溝３２は、拡散板２５と反射板２６の両側縁が上下に重なった状態できっちりと嵌まり込む溝幅に設定されている。拡散板２５の側縁が嵌まる嵌合溝と反射板２６の側縁が嵌まる嵌合溝とを別々に設けることも可能である。   As an example of a fitting portion of the circuit board 11, a first fitting groove 31 into which a long side edge of the circuit board 11 fits is formed on the inner surfaces of the two opposite side faces of the main cover body 10 a (that is, over the entire length). Formed so as to extend long in the X-axis direction). Furthermore, a pair of second fitting grooves 32 into which the long side edges of the diffusion plate 25 and the reflecting plate 26 are fitted are formed over the entire length at a position closer to the curved surface portion 15 than the first fitting portion 31 in the main cover body 10a. Has been. The second fitting groove 32 is set to have a groove width that fits tightly in a state where both side edges of the diffusion plate 25 and the reflection plate 26 overlap each other. It is also possible to separately provide a fitting groove into which the side edge of the diffusion plate 25 is fitted and a fitting groove into which the side edge of the reflection plate 26 is fitted.

第１嵌合溝３１と第２嵌合溝３２は主カバー体１０ａの一部として成形されており、光源ユニット１３や拡散板２５，反射板２６を厚さ方向と幅方向（Ｙ軸方向）にずれ不能に保持している。前述したように、主カバー体１０ａは合成樹脂を素材とした押し出し成形品であるため、各嵌合溝３１，３２は簡単に加工できる。   The first fitting groove 31 and the second fitting groove 32 are formed as a part of the main cover body 10a, and the light source unit 13, the diffusion plate 25, and the reflection plate 26 are arranged in the thickness direction and the width direction (Y-axis direction). It is kept incapable of slipping. As described above, since the main cover body 10a is an extruded product made of synthetic resin, the fitting grooves 31 and 32 can be easily processed.

補助カバー体１０ｂは主カバー体１０ａの裏蓋の役割を果たしており、図１（ｂ）に示すように主カバー体１０ａの内部に入り込む凸部１０ｃを有している。そして、凸部１０ｃには主カバー体１０ａの長溝１９ａが入り込む外向き凸条１０ｄを形成しており、この長溝１９ａと凸条１０ｄとの嵌まり合いによって主カバー体１０ａと補助カバー体１０ｂとは離反不能に保持されている。長溝１９ａと凸条１０ｄとの嵌め合いは、主カバー体１０ａと補助カバー体１０ｂとを長手方向にスライドさせることで行える。主カバー体１０ａの弾性変形を利用して、主カバー体１０ａと補助カバー体１０ｂとを補助カバー体１０ｂの厚さ方向に相対動させて、カバー体１０ａの弾性変形を利用した強制嵌合を採用することも可能である。   The auxiliary cover body 10b plays the role of a back cover of the main cover body 10a, and has a protrusion 10c that enters the main cover body 10a as shown in FIG. An outwardly protruding ridge 10d into which the long groove 19a of the main cover body 10a enters is formed in the convex portion 10c, and the main cover body 10a and the auxiliary cover body 10b are fitted by the fitting of the long groove 19a and the ridge 10d. Is held inseparable. The long groove 19a and the protrusion 10d can be fitted by sliding the main cover body 10a and the auxiliary cover body 10b in the longitudinal direction. Using the elastic deformation of the main cover body 10a, the main cover body 10a and the auxiliary cover body 10b are moved relative to each other in the thickness direction of the auxiliary cover body 10b to perform forced fitting using the elastic deformation of the cover body 10a. It is also possible to adopt.

上記構成の照明灯１を組み立てる際には、まず、主カバー体１０ａと補助カバー体１０ｂとを組み合わせて固着しカバー部材１０を形成した後に、光源ユニット１３の長手方向に沿う両側縁を、カバー部材１０の一方の端部にて、第１嵌合溝３１に位置合わせして、そのまま光源ユニット１３を挿入する。   When assembling the illuminating lamp 1 having the above-described configuration, first, the main cover body 10a and the auxiliary cover body 10b are combined and fixed to form the cover member 10, and then both side edges along the longitudinal direction of the light source unit 13 are covered with the cover. At one end of the member 10, the light source unit 13 is inserted as it is in alignment with the first fitting groove 31.

この実施形態では、反射板２６がＬＥＤ１２に嵌まっているので、光源ユニット１３の取り付けと同時に反射板２６も取り付けられる。すなわち、反射板２６の貫通穴２７からＬＥＤ１２が露出するように、反射板２６を光源ユニット１３にセットし、その状態で、光源ユニット１３の長手両側縁を主カバー体１０ａの第１嵌合溝３１に差し込むと共に、反射板２６の長手両側縁を主カバー体１０ａの第２嵌合溝３２に差し込む。拡散板２５は、光源ユニット１３と反射板２６とを差し込んでから主カバー体１０ａの第２嵌合溝３２に差し込んでも良いし、反射板２６に重ねた状態で゛反射板２６と一緒に第２嵌合溝３２に差し込んでも良い。   In this embodiment, since the reflection plate 26 is fitted to the LED 12, the reflection plate 26 is attached at the same time as the light source unit 13 is attached. That is, the reflecting plate 26 is set on the light source unit 13 so that the LED 12 is exposed from the through hole 27 of the reflecting plate 26, and in this state, the longitudinal both side edges of the light source unit 13 are the first fitting grooves of the main cover body 10a. 31 and the both longitudinal edges of the reflector 26 are inserted into the second fitting grooves 32 of the main cover body 10a. The diffusing plate 25 may be inserted into the second fitting groove 32 of the main cover body 10a after the light source unit 13 and the reflecting plate 26 are inserted, or the diffusion plate 25 may be put together with the reflecting plate 26 in a state of being superimposed on the reflecting plate 26. 2 may be inserted into the fitting groove 32.

主カバー体１０ａに対する光源ユニット１３と反射板２６と拡散板２５との取付け（嵌め込み）は、それら主カバー体１０ａと光源ユニット１３・反射板２６・拡散板２５とを長手方向に相対動させるだけで極めて簡単に行える。そして、光源ユニット１３はその全長にわたって第１嵌合溝３１で保持されているから、その長さが長くても、撓みを生じることなく安定した状態に保持される。また、光源ユニット１３は第１嵌合溝３１に挿入されているだけであるので、交換が必要な場合は容易に挿抜することができる。拡散板２５及び反射板２６も同様である。   The light source unit 13, the reflection plate 26, and the diffusion plate 25 are attached (fitted) to the main cover body 10a only by relatively moving the main cover body 10a, the light source unit 13, the reflection plate 26, and the diffusion plate 25 in the longitudinal direction. Is very easy to do. And since the light source unit 13 is hold | maintained in the 1st fitting groove 31 over the full length, even if the length is long, it is hold | maintained in the stable state, without producing a bending. Further, since the light source unit 13 is only inserted into the first fitting groove 31, it can be easily inserted and removed when replacement is necessary. The same applies to the diffusion plate 25 and the reflection plate 26.

カバー体１０ａ，１０ｂは押し出し成形品であるので、何本分もの長い長さの中間品を製造して、これを所望の長さに切断することで量産できる。長さの異なるものの製造も容易である。なお、カバー部材１０の長さは、照明灯１が一般的な直管型の蛍光灯のサイズ（例えば、管径３２．５ｍｍ×管長６３８ｍｍ、管径３２．５ｍｍ×管長８３０ｍｍ、管径２５．５ｍｍ×管長１１９８ｍｍ等）と同じサイズになるように設定されている。   Since the cover bodies 10a and 10b are extrusion-molded products, they can be mass-produced by manufacturing intermediate products having a long length and cutting them into desired lengths. Manufacture of different lengths is also easy. Note that the length of the cover member 10 is the same as the size of a straight tube fluorescent lamp in which the illuminating lamp 1 is general (for example, tube diameter 32.5 mm × tube length 638 mm, tube diameter 32.5 mm × tube length 830 mm, tube diameter 25. 5 mm × tube length 1198 mm, etc.).

一方、光源ユニット１３は、長手方向の一方の端部にオス型コネクタ２０が、他方の端部にメス型コネクタ２１が配置されている。そのため、図２（ｂ）に示すように光源ユニット１３を長手方向に沿って複数（ここでは３枚）並べ、図２（ａ）に示すように、隣り合ったオス型コネクタ２０とメス型コネクタ２１とを接続すると、一方のソケット部３側から供給された電力を順次隣接する光源ユニット１３に供給できる。つまり、図１に示す回路基板１１の長手方向の寸法をＬとすると、Ｌの略ｎ倍（ｎは正の数）の長さの光源ユニット１３を簡単に形成できるとともに、回路ユニット１３を共通部品として使用することによる部品コストの削減も可能となる。   On the other hand, the light source unit 13 has a male connector 20 disposed at one end in the longitudinal direction and a female connector 21 disposed at the other end. Therefore, a plurality (three in this case) of light source units 13 are arranged along the longitudinal direction as shown in FIG. 2 (b), and the adjacent male connector 20 and female connector as shown in FIG. 2 (a). When the power source 21 is connected, the power supplied from the one socket 3 side can be sequentially supplied to the adjacent light source units 13. That is, if the length in the longitudinal direction of the circuit board 11 shown in FIG. 1 is L, the light source unit 13 having a length approximately n times L (n is a positive number) can be easily formed, and the circuit unit 13 is shared. It is possible to reduce the cost of parts by using them as parts.

従って、光源ユニット１３をｎ個連結し、カバー部材１０はＬのｎ倍に対応する長さに切断加工することで、長さの異なる照明灯１を容易に製造することができる。そして、光源ユニット１３の全長がより一層長くなっていても、回路基板１１はその全長にわたって第１嵌合溝３１に嵌まっているので、組み立て・交換の容易や支持安定性が損なわれることはない。   Therefore, by connecting n light source units 13 and cutting the cover member 10 to a length corresponding to n times L, the illumination lamps 1 having different lengths can be easily manufactured. Even if the total length of the light source unit 13 is further increased, the circuit board 11 is fitted in the first fitting groove 31 over the entire length, so that the ease of assembly and replacement and the support stability are not impaired. Absent.

もちろん、Ｘ軸方向に長いカバー部材１０に対応させるために、あらかじめ、図２（ｃ）に示すように、寸法Ｌよりも長い１枚の光源ユニットを用意してもよいことは言うまでもない。また、長く製造された光源ユニットを、カバー部材１０の長さにあわせて切断して使用することも可能である。なお、図２（ａ）に示したオス型コネクタ２０とメス型コネクタ２１の形状は一例であって、これに限定するものではなく、端子が外部に突出していないタイプや、その他のタイプに適宜変更可能である。   Of course, in order to correspond to the cover member 10 that is long in the X-axis direction, it goes without saying that one light source unit longer than the dimension L may be prepared in advance as shown in FIG. Moreover, it is also possible to cut and use the light source unit manufactured long according to the length of the cover member 10. Note that the shapes of the male connector 20 and the female connector 21 shown in FIG. 2 (a) are merely examples, and the present invention is not limited to this, and may be appropriately selected for a type in which the terminal does not protrude to the outside or other types. It can be changed.

照明灯１は様々な形態で使用できる。例えば、図３（ａ）の第１変形使用例に示すように、照明装置２を回動式のソケット部３のみを有する構成として、これを直列状に複数配置してもよい。この場合には、回動式のソケット部３を回動させるためのスペースを隣り合った照明装置２の間に設ける必要がある。図３（ａ）では、両端のソケット部を共通化することでコスト削減を図っている。   The illumination lamp 1 can be used in various forms. For example, as shown in the first modified example of use in FIG. 3A, the lighting device 2 may have only the rotary socket portion 3 and a plurality of the lighting devices 2 may be arranged in series. In this case, it is necessary to provide a space for rotating the rotary socket portion 3 between the adjacent lighting devices 2. In FIG. 3A, the cost is reduced by sharing the socket portions at both ends.

さらに、照明灯１は、直列状の配置だけでなく、図３（ｂ）に第２変形使用例として示すように、平面視で多角形（ここでは四角形の場合を図示している）に配置することも可能である。この場合には、個々に独立した照明灯１を、単に平面視で多角形を構成するように配置してもよいが、２つのカバー部材１０を交差して連結できるキャップ体５を用いることによって、複数のカバー部材１０（図３（ｂ）では４つ）を四角形に連結し、１箇所のキャップ体５から電力を供給するようにしてもよい。   Furthermore, the illuminating lamp 1 is arranged not only in a series arrangement but also in a polygonal shape (here, a quadrangular case is illustrated) as shown in FIG. 3B as a second modified use example. It is also possible to do. In this case, the individually independent illumination lamps 1 may be arranged so as to form a polygon in a plan view, but by using the cap body 5 that can connect the two cover members 10 crossing each other. Alternatively, a plurality of cover members 10 (four in FIG. 3B) may be connected in a quadrangular shape and power may be supplied from one cap body 5.

ＬＥＤ１２を使用した照明灯１は照度・省電力・耐久性に優れているため、図３（ｃ）に第３変形使用例として示すように、照明装置２を天井設置式として、２４時間営業の店舗や公共施設などに用いると好適である。また、照明装置２の基部２ａにバッテリーを内蔵しておくとともに、停電により電源が切り替わるスイッチ回路を設けることで、災害時などの停電の際に非常灯として利用することもできる。   Since the illuminating lamp 1 using the LED 12 is excellent in illuminance, power saving, and durability, as shown in FIG. 3C as a third modified usage example, the illuminating device 2 is installed on the ceiling and is operated for 24 hours. It is suitable for use in stores and public facilities. Further, by providing a battery in the base 2a of the lighting device 2 and providing a switch circuit that switches the power supply due to a power failure, it can be used as an emergency light in the event of a power failure such as a disaster.

(2).カバー部材の別形態（図５）
次に、カバー部材１０の形状や内部構造の変形例を図４に基づいて説明する。図４（ａ）に示す第２実施形態は、拡散板２５と同様の機能を有する拡散部２５ａを、予め主カバー体１０ａにおける曲面部１５の内周面に形成した例である。つまり、主カバー体１０ａを押し出し成形で製造する際に、曲面部１５の内周面に拡散部２５ａとなる微細な多数の凹凸（長手方向に延びる凹凸の条）を形成したもので、これにより、部品管理が容易になると共に組み立ての手間も省くことができる。 (2). Another form of cover member (Fig. 5)
Next, a modified example of the shape and internal structure of the cover member 10 will be described with reference to FIG. The second embodiment shown in FIG. 4A is an example in which a diffusion portion 25a having the same function as the diffusion plate 25 is formed in advance on the inner peripheral surface of the curved surface portion 15 in the main cover body 10a. In other words, when the main cover body 10a is manufactured by extrusion molding, a large number of fine irregularities (longitudinal irregularities extending in the longitudinal direction) serving as the diffusion portions 25a are formed on the inner peripheral surface of the curved surface portion 15. As a result, parts management is facilitated and assembly work can be saved.

図４（ｂ）に示す第３変形例では、カバー部材１０はその軸心を挟んだ両側に２つの曲面部１５が設けられた断面小判形の筒形状に形成されており、２つの曲面部１５に対応して、片面にＬＥＤ１２を実装した２枚の光源ユニット１３が背中あわせに配置されている。   In the third modification shown in FIG. 4 (b), the cover member 10 is formed in a cylindrical shape having an oval cross section in which two curved surface portions 15 are provided on both sides of the axis, and the two curved surface portions are formed. Corresponding to 15, two light source units 13 having LEDs 12 mounted on one side are arranged back to back.

図４（ｃ）に示す第４実施形態では、主カバー体１０ａと補助カバー体１０ｂとの重ね合わせ部に嵌合溝３１ａを形成している。すなわち、補助カバー体１０ｂに設けた段付き部と主カバー体１０ａの平坦面とで嵌合溝３１ａを形成している。敢えて述べるまでもないが、主カバー体１０ａと補助カバー体１０ｂとはビス止め等の適宜手段で一体に保持されている。   In 4th Embodiment shown in FIG.4 (c), the fitting groove | channel 31a is formed in the overlapping part of the main cover body 10a and the auxiliary cover body 10b. That is, the fitting groove 31a is formed by the stepped portion provided in the auxiliary cover body 10b and the flat surface of the main cover body 10a. Needless to say, the main cover body 10a and the auxiliary cover body 10b are integrally held by appropriate means such as screws.

図４（ｄ）に示す第５実施形態では、カバー部材１０にフランジ状の取付部３５を設けて、この取付け部３５を壁面部４０や天井部等に固定するようにしている。照明灯１は、第１実施形態で示した照明装置２の基部２ａに直接固定することも可能である。   In the fifth embodiment shown in FIG. 4D, the cover member 10 is provided with a flange-like attachment portion 35, and the attachment portion 35 is fixed to the wall surface portion 40, the ceiling portion, or the like. The illuminating lamp 1 can also be directly fixed to the base 2a of the illuminating device 2 shown in the first embodiment.

図４（ｅ）に示す第６実施形態は、照明灯１を間接照明として天井部４１に取り付けた例である。つまり、この例では、主カバー体１０ａを、その曲面部１５が天井部４１に向けて凸となるように配置して、ＬＥＤ１２の光が天井部４１に向かって発光するように構成し、更に、補助カバー体１０ｂに設けたフランジ状の取付部３５を天井部４１に固定すると共に、天井部４１の側に反射板２６を配置している。ＬＥＤ１２は発光が強いため、間接照明として利用しても十分な照度を得ることができる。   6th Embodiment shown in FIG.4 (e) is an example which attached the illuminating lamp 1 to the ceiling part 41 as indirect illumination. That is, in this example, the main cover body 10a is arranged such that the curved surface portion 15 is convex toward the ceiling portion 41, and the light of the LED 12 is configured to emit light toward the ceiling portion 41. The flange-shaped attachment portion 35 provided on the auxiliary cover body 10b is fixed to the ceiling portion 41, and the reflection plate 26 is disposed on the ceiling portion 41 side. Since the LED 12 emits light strongly, sufficient illuminance can be obtained even when used as indirect illumination.

図４（ｆ）に第７実施形態は第３実施形態と類似したものであり、カバー部材１０を円筒形状に形成して、その内部に、表裏両面にＬＥＤ１２を実装した光源ユニット１３が配置されている。この実施形態では照明灯１はほぼ全周にわたって面発光する。従って、街路灯のように周囲の全体を照らす必要がある場合に好適である。これにも反射板２６や拡散板２５を併用できることは云うまでもない。   In FIG. 4 (f), the seventh embodiment is similar to the third embodiment, in which the cover member 10 is formed in a cylindrical shape, and the light source unit 13 in which the LEDs 12 are mounted on both the front and back surfaces is disposed therein. ing. In this embodiment, the illuminating lamp 1 emits light over substantially the entire circumference. Therefore, it is suitable when it is necessary to illuminate the entire surroundings like a street lamp. Needless to say, the reflecting plate 26 and the diffusing plate 25 can be used together.

図４（ｇ）に示す第８実施形態では、カバー部材１０を円筒形状に形成し、その内部に、片面にＬＥＤ１２が実装された光源ユニット１３を挿入しているが、カバー部材１０における発光面積を広く取るために、光源ユニット１３を、ＬＥＤ１２が配置された側と反対側のカバー部材１０の外周に近づくように軸心に対してずらし配置している。   In the eighth embodiment shown in FIG. 4G, the cover member 10 is formed in a cylindrical shape, and the light source unit 13 having the LED 12 mounted on one side is inserted therein. In order to obtain a wide range, the light source unit 13 is shifted from the axial center so as to approach the outer periphery of the cover member 10 on the side opposite to the side on which the LEDs 12 are disposed.

図４で図示した実施形態の他に、例えば、カバー部材１０（主カバー体１０ａ、補助カバー体１０ｂ）を合成樹脂で押し出し成形するときに、共押し出し法により、透光性の異なる樹脂（透光性樹脂、遮光性樹脂、半透明な樹脂等）を組み合わせたり、色の異なる樹脂を組み合わせたりして成形し、透光性や色彩に部分的な差異を設けるようにしてもよい。   In addition to the embodiment illustrated in FIG. 4, for example, when the cover member 10 (the main cover body 10 a and the auxiliary cover body 10 b) is extruded with a synthetic resin, a resin (translucent resin) having different translucency is obtained by a co-extrusion method. (A light resin, a light shielding resin, a translucent resin, etc.) or a resin having a different color may be combined to form a partial difference in translucency and color.

(3).第９実施形態（図５）
第９実施形態として示すように、カバー部材１０は円環状（リング状）に形成することも可能である（多角形のような非円形の環状の形態と成すことも可能である。）。これは請求項３を具体化したものである。 (3). Ninth embodiment (FIG. 5)
As shown as the ninth embodiment, the cover member 10 can be formed in an annular shape (ring shape) (it can also be formed in a non-circular annular shape such as a polygon). This is the embodiment of claim 3.

カバー部材１０は、光源ユニット１３をＬＥＤ１２が実装された側から覆う主カバー体１０ａ（請求項３の第１カバー体に相当する）１５と、ＬＥＤ１２と反対側から覆う補助カバー体１０ｂ（請求項３の第２カバー体に相当する）とで中空に構成されている。すなわち、カバー部材１０は半割り状の主カバー体１０ａと補助カバー体１０ｂとで構成されていてい、その内部に光源ユニット１３が配置されている。   The cover member 10 includes a main cover body 10a (corresponding to the first cover body of claim 3) 15 that covers the light source unit 13 from the side on which the LED 12 is mounted, and an auxiliary cover body 10b that covers the light source unit 13 from the side opposite to the LED 12 (claim). 3 corresponding to the second cover body 3). That is, the cover member 10 includes a half-shaped main cover body 10a and an auxiliary cover body 10b, and the light source unit 13 is disposed therein.

図５（ｂ）に示すように、主カバー体１５と補助カバー体１６とは略Ｕ字状（或いは半円状）の断面形状であり、開口端を互いに重ね合わせることで全体として中空の形態を成している。
そして、主カバー体１０ａと補助カバー体１０ｂとの重なり合う部分に嵌合溝３１ａが形成されている。主カバー体１０ａと補助カバー体１０ｂとは射出成形法で製造されていて、互いに嵌り合うことで位置決めされている。 As shown in FIG. 5B, the main cover body 15 and the auxiliary cover body 16 have a substantially U-shaped (or semicircular) cross-sectional shape, and are hollow as a whole by overlapping the open ends with each other. Is made.
A fitting groove 31a is formed in an overlapping portion between the main cover body 10a and the auxiliary cover body 10b. The main cover body 10a and the auxiliary cover body 10b are manufactured by an injection molding method, and are positioned by fitting each other.

光源ユニット１３の回路基板１１は、１枚の回路基板によって平面視リング状に形成してもよいが、部品コストが嵩むため、リングを分割した円弧状の回路基板を複数連結することによって平面視リング状にしている。ここでは、４つの光源ユニット１３を用い、接続部２２によって基板同士を物理的に連結するとともに、電気的にも接続している。また、連結された光源ユニット１３はカバー部材１０の円周上の１箇所に設けられた接続部６に電気的に接続されていて、この接続部６に電源コネクタ７が差し込まれることでＬＥＤ１２に給電されている。   The circuit board 11 of the light source unit 13 may be formed in a ring shape in plan view with a single circuit board. However, since the component cost increases, a plurality of arc-shaped circuit boards having divided rings are connected in plan view. It has a ring shape. Here, the four light source units 13 are used, and the substrates are physically connected to each other by the connecting portion 22 and are also electrically connected. Further, the connected light source unit 13 is electrically connected to a connection portion 6 provided at one place on the circumference of the cover member 10, and the power connector 7 is inserted into the connection portion 6 so that the LED 12 is connected. Power is being supplied.

補助カバー体１０ｂのうち主カバー体１０ａと対向する面には、嵌合溝３１ａと成る段部が形成されていて、各基板１１はその両側縁が嵌合溝３１ａに嵌め込まれている。主カバー体１０ａと補助カバー体１０ｂには、これらをねじ１９で固定するためのスペースとして、内周側に出っ張った固定部１０ｅ，１０ｆが、周方向に間隔をあけて複数箇所設けられている（図１０（ａ）では１箇所のみ図示している。）。従って、補助カバー体１０ｂと主カバー体１０ａとをねじ１９で固定するで、補助カバー体１０ｂと主カバー体１０ａとの間に光源ユニット１３が挟持される。   On the surface of the auxiliary cover body 10b that faces the main cover body 10a, a stepped portion that becomes a fitting groove 31a is formed, and each side edge of each substrate 11 is fitted into the fitting groove 31a. The main cover body 10a and the auxiliary cover body 10b are provided with a plurality of fixing portions 10e and 10f protruding on the inner peripheral side at intervals in the circumferential direction as spaces for fixing them with the screws 19. (In FIG. 10A, only one location is shown.) Therefore, the light source unit 13 is sandwiched between the auxiliary cover body 10b and the main cover body 10a by fixing the auxiliary cover body 10b and the main cover body 10a with the screws 19.

ここでは、図５（ｂ）に示すように、主カバー体１０ａと光源ユニット１３との間には湾曲した断面形状の拡散板２５が配置されていて、拡散板２５の両側縁も光源ユニット１３と重なった状態で嵌合溝３１ａに嵌まっている。なお、拡散板２５は、予め主カバー体１０ａの曲面部１５に密着させておいたり、主カバー体１０ａの内周面に二色成形法等にて一体的に形成しておいたりしてもよい。   Here, as shown in FIG. 5B, a diffuser plate 25 having a curved cross-sectional shape is disposed between the main cover body 10a and the light source unit 13, and both side edges of the diffuser plate 25 are also disposed on the light source unit 13. And is fitted in the fitting groove 31a. The diffusion plate 25 may be previously brought into close contact with the curved surface portion 15 of the main cover body 10a, or may be integrally formed on the inner peripheral surface of the main cover body 10a by a two-color molding method or the like. Good.

この実施形態でも、光源ユニット１３は、その全長に亙って主カバー体１０ａと補助カバー体１０ｂとで挟持されるため、安定的に保持される。また、光源ユニット１３は主カバー体１０ａと補助カバー体１０ｂとの組み付けに際して簡単にセットできる。この環状のカバー部材１０の構成は、図４（ａ），（ｃ），（ｄ），（ｅ）の実施形態に適用することも可能である。また、図４（ｂ），（ｆ），（ｇ）の例を第９実施形態のように２つのカバー体で構成することに適用しても良い。   Also in this embodiment, the light source unit 13 is stably held because it is sandwiched between the main cover body 10a and the auxiliary cover body 10b over its entire length. The light source unit 13 can be easily set when the main cover body 10a and the auxiliary cover body 10b are assembled. The configuration of the annular cover member 10 can also be applied to the embodiments of FIGS. 4 (a), (c), (d), and (e). Moreover, you may apply to comprising the example of FIG.4 (b), (f), (g) by two cover bodies like 9th Embodiment.

(4).第１０実施形態（図６）
次に、図６に表示した第１０実施形態を用いて説明する。なお、第１実施形態と同じ要素は同じ符号を付して詳細な説明は省略する。 (4). Tenth embodiment (FIG. 6)
Next, a description will be given using the tenth embodiment displayed in FIG. In addition, the same element as 1st Embodiment attaches | subjects the same code | symbol, and abbreviate | omits detailed description.

この第１０実施形態では、蛍光灯用照明装置１０２の本体（器具）を利用して、照明灯１０１を蛍光灯に置き換えできるようにしたものである。すなわち、照明装置１０２のソケット部１０３，１０４の内部に蛍光灯用に設けられていた接続部を照明灯１０１用の接続部１０３ａ，１０４ａに付け替えることにより、照明灯１０１を使用できるようにしている。接続部のみを置換するのではなく、ソケット部全体を照明灯１０１用に付け替えしてもよい。   In the tenth embodiment, the main body (apparatus) of the fluorescent lamp illumination device 102 is used to replace the illumination lamp 101 with a fluorescent lamp. That is, the illumination lamp 101 can be used by replacing the connection sections provided for the fluorescent lamps in the socket sections 103 and 104 of the illumination apparatus 102 with the connection sections 103a and 104a for the illumination lamp 101. . Instead of replacing only the connecting portion, the entire socket portion may be replaced for the illumination lamp 101.

ＡＣ／ＤＣ変換器や電圧制御部を含む回路部１４を、基部１０２ａの内部に設けている。蛍光灯用に設けられている安定器は照明灯１０１には不要であるため、接続部１０３ａ，１０４ａは安定器には接続していない。そして、回路部１４及び一方の接続部１０３ａを介してＬＥＤ１２側に電力を供給できるようにし、他方の接続部１０３ｂは電気的な接続に用いないように構成している。なお、回路部１４は小型化して、接続部１０３ａに内蔵したり、光源ユニット１３に実装したりしてもよい。   A circuit unit 14 including an AC / DC converter and a voltage control unit is provided in the base 102a. Since the ballast provided for the fluorescent lamp is not necessary for the illumination lamp 101, the connecting portions 103a and 104a are not connected to the ballast. Then, power can be supplied to the LED 12 via the circuit portion 14 and one connection portion 103a, and the other connection portion 103b is not used for electrical connection. The circuit unit 14 may be downsized and built in the connection unit 103 a or mounted on the light source unit 13.

カバー部材１０の一端に取り付けられた第１キャップ体１１７は、外方に突出する端子１１７ａを有し、第１キャップ体１１７をカバー部材１０に嵌め込むことで、端子１１７ａとオス型コネクタ２０とが電気的に接続される。ここでは第１キャップ体１１７は２つの部材で構成されている。照明灯１０１がソケット部１０３に嵌め込まれると、第１キャップ体１１７の端子１１７ａを介して、オス型コネクタ２０と接続部１０３ａとが電気的に接続され、ＬＥＤ１２を発光させることが可能となる。   The first cap body 117 attached to one end of the cover member 10 has a terminal 117a that protrudes outward. By fitting the first cap body 117 into the cover member 10, the terminal 117a, the male connector 20, Are electrically connected. Here, the first cap body 117 is composed of two members. When the illuminating lamp 101 is fitted into the socket portion 103, the male connector 20 and the connection portion 103a are electrically connected via the terminal 117a of the first cap body 117, and the LED 12 can be caused to emit light.

カバー部材１０の他端に取り付けられた第２キャップ体１１８は、外方に突出して接続部１０４ａに差し込まれる端子１１８ａを有しているが、ＬＥＤ１２はオス型コネクタ２０側からの電力の供給だけで発光させることができるため、端子１１８ａは電気的な接続がなされないダミー端子となっている。つまり、端子１１８ａは電気的には使用されず、照明装置１０２に対する照明灯１０１の嵌め込み保持用として使用されている。   The second cap body 118 attached to the other end of the cover member 10 has a terminal 118a that protrudes outward and is inserted into the connection portion 104a. However, the LED 12 can only supply power from the male connector 20 side. Therefore, the terminal 118a is a dummy terminal that is not electrically connected. That is, the terminal 118 a is not electrically used, but is used for fitting and holding the illumination lamp 101 with respect to the illumination device 102.

接続部１０３ａはソケット部１０３に対してＸ軸方向に弾性変位可能（可動式）に形成されている一方、接続部１０４ａはソケット部１０４に対して変位不能（固定式）に形成されている。従って、照明灯１０１を取り付ける際には、端子１１７ａを接続部１０３ａに差し込んで奥側に変位させた後、接続部１０３ａを元の位置に戻しながら、端子１１８ａを接続部１０４ａに差し込むという手順を採ることになる。   The connection portion 103a is formed to be elastically displaceable (movable) in the X-axis direction with respect to the socket portion 103, while the connection portion 104a is formed to be non-displaceable (fixed) with respect to the socket portion 104. Therefore, when attaching the illuminating lamp 101, after inserting the terminal 117a into the connecting portion 103a and displacing it to the inner side, the terminal 118a is inserted into the connecting portion 104a while returning the connecting portion 103a to the original position. I will take it.

この取り付け方式に代えて、接続部１０３ａ、１０４ａに、端子１１７ａ，１１８ａをその軸線に直交する方向にスライドさせて差し込むことができる溝形部を設けておいて、溝形部に端子１１７ａ，１１８ａを差し込んだ後に照明灯１０１と共に接続部１０３ａ，１０４ａを９０度ほど回転させる方式にしてもよい。この回転方式の場合には、回転後にＬＥＤ１２が基部１０２ａと反対側を向くように、予め端子１１７ａ，１１８ａの配置を設定しておかねばならない。   Instead of this mounting method, a groove-shaped portion is provided in the connecting portions 103a, 104a so that the terminals 117a, 118a can be slid in a direction perpendicular to the axis thereof, and the terminals 117a, 118a are provided in the groove-shaped portions. Alternatively, the connecting portions 103a and 104a may be rotated about 90 degrees together with the illuminating lamp 101. In the case of this rotation method, the arrangement of the terminals 117a and 118a must be set in advance so that the LED 12 faces the side opposite to the base 102a after the rotation.

なお、第２〜第９実施形態として例示した直線状や環状の構成を、第２実施形態のように蛍光灯代替式の照明灯１に適用してもよい。   In addition, you may apply the linear or cyclic | annular structure illustrated as 2nd-9th embodiment to the fluorescent lamp alternative type illumination lamp 1 like 2nd Embodiment.

この第１０実施形態では、ソケット部１０３，１０４は固定式であって互いの間隔は一定であるため、図６（ｂ）に示すように、複数の照明灯１０１を互いに密着した状態で直列配置することができる。   In the tenth embodiment, since the socket portions 103 and 104 are fixed and have a constant distance from each other, as shown in FIG. 6B, a plurality of illumination lamps 101 are arranged in series in close contact with each other. can do.

(5).第１１実施形態（図７）
次に、図７に表示した第１１実施形態の照明灯２０１を説明する。この実施形態は請求項５を具体化したものであり、第１実施形態と同様の要素には同じ符号を付して詳細な説明は省略する。この第１１実施形態はＸ軸方向に細長く延びる導光体５０を有しており、この導光体５０の長手方向の一端面と他端面とにエンド部材２２０を配置し、両方のエンド部材２２０に、導光体５０に向かけて光を照射するＬＥＤ１２が設けられている。 (5). Eleventh embodiment (FIG. 7)
Next, the illumination lamp 201 of the eleventh embodiment displayed in FIG. 7 will be described. This embodiment embodies Claim 5 and the same reference numerals are given to the same elements as those in the first embodiment, and the detailed description is omitted. The eleventh embodiment includes a light guide 50 that is elongated in the X-axis direction. End members 220 are disposed on one end surface and the other end surface of the light guide 50 in the longitudinal direction. Further, an LED 12 that irradiates light toward the light guide 50 is provided.

導光体５０は、その外周面５０ａと内周面５０ｂがいずれも同じ方向に湾曲した横断面Ｕ字状に形成されている。導光体５０の外周面５０ａは、多数の微細な凹凸が形成されている拡散板２２５で覆われて、導光体５０の内周面５０ｂは、反射板２２６を介在させて内周カバー部材２１０で覆われている。そのため、拡散板２２５と反射板２２６と内周カバー部材２１０とは、いずれも導光体５０の形状に沿うようにＸ軸方向に長い断面略Ｕ字状に形成されている。   The light guide 50 is formed in a U-shaped cross section in which the outer peripheral surface 50a and the inner peripheral surface 50b are both curved in the same direction. The outer peripheral surface 50a of the light guide 50 is covered with a diffusion plate 225 on which a number of fine irregularities are formed, and the inner peripheral surface 50b of the light guide 50 is provided with an inner peripheral cover member with a reflector 226 interposed therebetween. 210 is covered. Therefore, the diffusion plate 225, the reflection plate 226, and the inner cover member 210 are all formed in a substantially U-shaped cross section that is long in the X-axis direction so as to follow the shape of the light guide 50.

導光体５０は、透光性樹脂の一例としてのアクリル材で形成されている。そして、図７（ｅ）の模式的拡大図に示しているように、導光体５０の内周面５０ｂには、稜線が導光体５０の軸線と交差した方向に延びる多数の山形の起伏を形成している。従って、導光体５０の内部をＸ軸方向に進む光は、多数の山形の起伏に当たることでプリズム現象によって屈折して向きを変えて、外周面５０ｂから出射する。なお、屈折手段は、前述した山形の起伏に限定するものではなく、他の形態を適用してもよい。   The light guide 50 is formed of an acrylic material as an example of a translucent resin. Then, as shown in the schematic enlarged view of FIG. 7 (e), on the inner peripheral surface 50 b of the light guide 50, a number of mountain-shaped undulations extending in the direction in which the ridge line intersects the axis of the light guide 50. Is forming. Accordingly, the light traveling in the X-axis direction inside the light guide 50 is refracted and changed its direction by the prism phenomenon by hitting a large number of mountain-shaped undulations, and is emitted from the outer peripheral surface 50b. The refracting means is not limited to the above-described mountain-shaped undulations, and other forms may be applied.

導光体５０の外周面５０ａは拡散部２２５で覆われているから、導光体５０の外周面５０ａから出射した光は拡散部２２５を通って拡散されて、拡散部２２５の外周面５０ａがＸ軸方向に亙って面発光している状態になる。また、導光体５０の内周面５０ｂに反射板２２６を設けているから、導光体５０の内周面５０ｂから出た光は反射して、外周面５０ａ側に再び向きを変えるので、照明効率を上げることができる。反射板２２６を拡散板２２５に替えても同様の効果が得られる。   Since the outer peripheral surface 50a of the light guide 50 is covered with the diffusion portion 225, the light emitted from the outer peripheral surface 50a of the light guide 50 is diffused through the diffusion portion 225, and the outer peripheral surface 50a of the diffusion portion 225 is Surface emission occurs in the X-axis direction. Moreover, since the reflecting plate 226 is provided on the inner peripheral surface 50b of the light guide 50, the light emitted from the inner peripheral surface 50b of the light guide 50 is reflected and redirected to the outer peripheral surface 50a side. Lighting efficiency can be increased. The same effect can be obtained even if the reflection plate 226 is replaced with the diffusion plate 225.

光源ユニット２１３の回路基板１１は、導光体５０の両端を覆うように平面視蒲鉾形状に形成されていて（図７（ｄ）参照）、ＬＥＤ１２は、導光体５０に向かって発光するように光源ユニット２１３に取り付けられて、導光体５０に当接している。図７（ｂ）及び（ｄ）に示すように、ここでは３個のＬＥＤ１２が１枚の回路基板１１に円弧状に配置されているが、一方の光源ユニット２１３のＬＥＤ１２と他方の光源ユニット２１３のＬＥＤ１２とは、Ｘ軸方向からの投影視で周方向に略等間隔ずつ位置ずれした状態に配置されている。説明の便宜上、図７（ｃ）では、導光体５０の手前側にあるＬＥＤを破線で、向こう側にあるＬＥＤを実線で図示している。   The circuit board 11 of the light source unit 213 is formed in a plan view shape so as to cover both ends of the light guide 50 (see FIG. 7D), and the LED 12 emits light toward the light guide 50. The light source unit 213 is attached to the light guide 50. As shown in FIGS. 7B and 7D, here, the three LEDs 12 are arranged in an arc shape on one circuit board 11, but the LEDs 12 of one light source unit 213 and the other light source unit 213 are arranged. The LEDs 12 are arranged in a state of being displaced by substantially equal intervals in the circumferential direction when viewed from the X-axis direction. For convenience of explanation, in FIG. 7C, the LEDs on the near side of the light guide 50 are indicated by broken lines, and the LEDs on the far side are indicated by solid lines.

このように２つの光源ユニット２１３のＬＥＤ１２の配置を投影視で周方向に位置ずれさせて並べると、導光体５０の両端から入射したＬＥＤ１２の光が内部で緩衝することを回避できる利点や、１つの回路基板１１におけるＬＥＤ１２の配置間隔を広げることができて回路基板１１へのＬＥＤ１２の取り付けが容易になる利点がある。光源ユニット２１３には、図７（ａ）及び（ｂ）に示すように、ＬＥＤ１２が実装された面の反対側の面に、ＬＥＤ１２と電気的に接続された端子２１３ａを突設している。   In this way, if the arrangement of the LEDs 12 of the two light source units 213 is arranged with the positions shifted in the circumferential direction in projection view, the advantage that the light of the LEDs 12 incident from both ends of the light guide 50 can be prevented from being buffered inside, There is an advantage that the arrangement interval of the LEDs 12 on one circuit board 11 can be widened and the LED 12 can be easily attached to the circuit board 11. As shown in FIGS. 7A and 7B, the light source unit 213 is provided with a terminal 213a that is electrically connected to the LED 12 on the surface opposite to the surface on which the LED 12 is mounted.

導光体５０の長手方向の両端面には、まず光源ユニット２１３を導光体５０に対して位置決めするための位置決め部材２１７が配置され、そのＸ軸方向の外側に光源ユニット２１３が配置される。光源ユニット２１３の更に外側にはスペーサ部材２１９，キャップ部材２１８が順次配置され、これらが導光体５０に対してねじ１９で共締めされて固定されている。この実施形態では、光源ユニット２１３，位置決め部材２１７，スペーサ部材２１９，キャップ部材２１８が請求項５に記載したエンド部材２２０に相当するが、エンド部材２２０の構成はこれに限定されるものではない。   First, positioning members 217 for positioning the light source unit 213 with respect to the light guide 50 are arranged on both end faces in the longitudinal direction of the light guide 50, and the light source unit 213 is arranged outside the X-axis direction. . A spacer member 219 and a cap member 218 are sequentially arranged on the outer side of the light source unit 213, and these are fixed to the light guide 50 by being fastened together with screws 19. In this embodiment, the light source unit 213, the positioning member 217, the spacer member 219, and the cap member 218 correspond to the end member 220 described in claim 5, but the configuration of the end member 220 is not limited to this.

スペーサ部材２１９及びキャップ体２１８には、端子２１３ａをソケット部２０３，２０４側に突出させる穴部が設けられている。キャップ体２１８から外方に突出した端子２１３ａは、ソケット部２０３，２０４に電気的に接続される。この実施形態では、導光体５０の両端に取り付けられた２つの光源ユニット２１３は電気的に接続されてはいないため、それぞれに対応するソケット部２０３，２０４から端子２１３ａを介して電力が供給されるが、２つの光源ユニット２１３を照明灯２０１の内側で連結して、電力の供給を一方のソケット部２０３側から行うようにしてもよい。   The spacer member 219 and the cap body 218 are provided with holes for projecting the terminals 213a toward the sockets 203 and 204. The terminal 213a protruding outward from the cap body 218 is electrically connected to the socket portions 203 and 204. In this embodiment, since the two light source units 213 attached to both ends of the light guide 50 are not electrically connected, power is supplied from the corresponding socket portions 203 and 204 via the terminals 213a. However, the two light source units 213 may be connected inside the illuminating lamp 201 so that power is supplied from one socket 203 side.

なお、一方のソケット部２０３の接続部２０３ａは、Ｘ軸方向に沿って弾性変位可能に構成されているので、照明装置２に対する照明灯２０１の着脱は、接続部２０３ａの弾性変位を利用して行われる。   In addition, since the connection part 203a of one socket part 203 is comprised so that elastic displacement is possible along the X-axis direction, the attachment or detachment of the illuminating lamp 201 with respect to the illuminating device 2 utilizes the elastic displacement of the connection part 203a. Done.

第３実施形態では、導光体５０がＸ軸方向に長く形成されているが、光源ユニット２１３は、導光体５０の長手方向の両端面に配置するだけでよい。つまり、ＬＥＤ１２を光源とした直線形状の細長い照明灯２０１であるが、光源ユニット２１３を長尺に形成する必要はないため、光源ユニット２１３を含むエンド部材２２０を導光体５０の端面に強固に且つ簡単に取り付けることができる。そのため、光源ユニット２１３の撓みによる破損を懸念する必要がない。   In the third embodiment, the light guide 50 is formed long in the X-axis direction, but the light source unit 213 only needs to be disposed on both end faces of the light guide 50 in the longitudinal direction. That is, although it is the linear elongated illuminating lamp 201 using the LED 12 as a light source, it is not necessary to form the light source unit 213 to be long, and therefore the end member 220 including the light source unit 213 is firmly attached to the end surface of the light guide 50. And it can be easily attached. Therefore, there is no need to worry about damage due to bending of the light source unit 213.

なお、第１１実施形態では、導光体５０のＸ軸方向の両端面に光源ユニット２１３を取り付けているが、いずれか一方のみに取り付けるだけでもよい。また導光体５０の形状は図７に示した形状に限定されるものではなく、図７（ａ）に一点鎖線で示すように、凹凸が形成されている内周面５０ｂを、入射位置から離れるに従って外周面５０ａに近づけるように傾斜させると、内周面５０ｂに対するＬＥＤ１２の照射率が高まるため、屈折効率を向上させることができる。更に、ＬＥＤ１２はエンド部材２２０に固定せずに、エンド部材２２０と導光体５０との間に挟まれた状態のままとしてもよいし、或いは導光体５０の端面にネジ等で固定してもよい。   In addition, in 11th Embodiment, although the light source unit 213 is attached to the both end surfaces of the X-axis direction of the light guide 50, you may attach only to either one. Further, the shape of the light guide 50 is not limited to the shape shown in FIG. 7, and the inner peripheral surface 50 b on which the irregularities are formed is formed from the incident position, as indicated by a one-dot chain line in FIG. If the LED 12 is inclined so as to be closer to the outer peripheral surface 50a as the distance is increased, the irradiation rate of the LED 12 with respect to the inner peripheral surface 50b is increased, so that the refractive efficiency can be improved. Further, the LED 12 may not be fixed to the end member 220 but may be sandwiched between the end member 220 and the light guide 50, or may be fixed to the end surface of the light guide 50 with screws or the like. Also good.

(6).第１２実施形態（図８〜図１１）
次に、図８〜図１１に表示した第１２実施形態を説明する。この実施形態は基本的には第１実施形態に似ており、カバー部材１０を主カバー体１０ａと補助カバー体１０ｂとで構成して、その内部に光源ユニット１３を配置している。第１実施形態と同様に反射板２６を有するが拡散板２５は備えていない。本実施形態では反射板２６と補助カバー体１０ｂとが請求項に記載した保持部材を兼用しており、従って、主カバー体１０ａが請求項に記載したカバー部材に相当する。補助カバー体１０ｂはアルミのような軽金属を材料とした押し出し品を使用している。 (6). Twelfth embodiment (FIGS. 8 to 11)
Next, a twelfth embodiment displayed in FIGS. 8 to 11 will be described. This embodiment is basically similar to the first embodiment, and the cover member 10 is composed of a main cover body 10a and an auxiliary cover body 10b, and the light source unit 13 is disposed therein. Similar to the first embodiment, the reflector 26 is provided but the diffuser 25 is not provided. In the present embodiment, the reflecting plate 26 and the auxiliary cover body 10b also serve as the holding member recited in the claims, and therefore the main cover body 10a corresponds to the cover member recited in the claims. The auxiliary cover body 10b uses an extruded product made of a light metal such as aluminum.

図９及び図１１に示すように、主カバー体１０ａは第１実施形態と同様に湾曲部１５を有する断面Ｕ字形に形成されており、相対向した２つの内側面には嵌合部の一例としての蟻溝状の嵌合溝５１を形成している。他方、補助カバー体１０ｂは第１実施形態と同様に内向きの凸部１０ｃを有しており、凸部１０ｃに、ねじ１９をねじ込む長溝１９ａが内向きに開口した状態で形成されていると共に、主カバー体１０ａの嵌合溝５１に嵌まる横向き凸条５２が形成されている。   As shown in FIGS. 9 and 11, the main cover body 10a is formed in a U-shaped cross section having a curved portion 15 as in the first embodiment, and an example of a fitting portion is provided on two opposed inner surfaces. The dovetail-like fitting groove 51 is formed. On the other hand, the auxiliary cover body 10b has an inward convex portion 10c as in the first embodiment, and a long groove 19a into which the screw 19 is screwed is formed in the convex portion 10c so as to open inward. Lateral ridges 52 that fit into the fitting grooves 51 of the main cover body 10a are formed.

図１１（Ｃ）に明示するように、補助カバー体１０ｂの凸部１０ｃには、長溝１９ａ及び横向き凸条５２から更に主カバー体１０ａの内部に向けて突出した断面鉤形の係合爪条５３が形成されている。係合爪条５３は、図１１（ｂ）（ｃ）において左右外側に突出した爪を有している。また、補助カバー体１０ｂのうち主カバー体１０ａと反対側の基部には、主カバー体１０ａの２つの側面部に近接した状態で左右２つの蟻溝状取付け溝５４が形成されている。取付け溝５４は概ね台形に近い形状であり、補助カバー体１０ｂの基部には取付け溝５４を形成するため内向きフランジ５５が形成されている。   As clearly shown in FIG. 11 (C), the protrusion 10c of the auxiliary cover body 10b has a hook-shaped engagement claw that protrudes further from the long groove 19a and the lateral protrusion 52 toward the inside of the main cover body 10a. 53 is formed. The engaging claw 53 has a claw protruding outward in the left and right directions in FIGS. In addition, two dovetail mounting grooves 54 on the left and right sides are formed on the base portion of the auxiliary cover body 10b opposite to the main cover body 10a so as to be close to the two side surfaces of the main cover body 10a. The mounting groove 54 has a substantially trapezoidal shape, and an inward flange 55 is formed at the base of the auxiliary cover body 10b to form the mounting groove 54.

更に、内向きフランジ５５の左右外側には外向きフランジ５６が形成されており、主カバー体１０ａの長く延びる側端面は外向きフランジ５６と密着又は近接している。従って、補助カバー体１０ｂの外向きフランジ５６は主カバー体１０ａの側面部を構成しており、外部から視認できる。補助カバー体１０ｂのうち横向き凸状５２と外向きフランジ５６との間の部分は係合溝５７になっており、この係合溝５７に主カバー体１０ａの内向き係合凸条５８が嵌まっている。従って、本実施形態では係合溝５８と係合凸条５８も嵌合手段を構成しており、請求項に則して述べると、主カバー体１０ａは、係合凸条５８も嵌合部を構成している（嵌合溝５１を無くして係合凸条５８のみとすることも可能である。）。   Further, outward flanges 56 are formed on the left and right outer sides of the inward flange 55, and the side end surfaces of the main cover body 10 a that extend long are in close contact with or close to the outward flange 56. Accordingly, the outward flange 56 of the auxiliary cover body 10b constitutes a side surface portion of the main cover body 10a and can be visually recognized from the outside. A portion of the auxiliary cover body 10 b between the lateral convex 52 and the outward flange 56 is an engagement groove 57, and the inward engagement protrusion 58 of the main cover body 10 a is fitted into the engagement groove 57. waiting. Accordingly, in the present embodiment, the engaging groove 58 and the engaging ridge 58 also constitute the fitting means. According to the claims, the main cover body 10a includes the engaging ridge 58 and the fitting portion. (It is also possible to eliminate the fitting groove 51 and use only the engaging protrusion 58).

取付け溝５４は、図１１（ｄ）に明示する支持金具５９に嵌め込むことができる。すなわち、支持金具５９は天井や壁等の施行部６０にねじ６１で固定されるもので、逆ハの字形に広がった２枚の側板６２を有しており、この側板６２の先端に、取付け溝５４に入り込む爪片６３を折り曲げ形成している。爪片６３が内向きフランジ５５に引っ掛かることで、補助カバー体１０ｂは施行部６０に脱落不能に保持される。支持金具５９には、補助カバー体１０ｂの底面に弾性的に戸は当接する押圧片６４を曲げ形成している。この押圧片６４の存在により、補助カバー体１０ｂはガタ付きのない状態に保持される。   The attachment groove 54 can be fitted into the support fitting 59 clearly shown in FIG. That is, the support bracket 59 is fixed to the enforcement portion 60 such as a ceiling or a wall with screws 61, and has two side plates 62 spread in a reverse letter C shape. A claw piece 63 entering the groove 54 is bent. When the claw piece 63 is caught by the inward flange 55, the auxiliary cover body 10 b is held by the enforcement portion 60 so as not to drop off. The support fitting 59 is formed by bending a pressing piece 64 that elastically contacts the bottom surface of the auxiliary cover body 10b. Due to the presence of the pressing piece 64, the auxiliary cover body 10b is held in a state without backlash.

補助カバー体１０ｂを支持金具５９に脱落不能に保持する手段としては、側板６２に爪片６３を設けることに代えて）又はこれに加えて）、図１１（ｅ）に実線て示すと共に図１１（ｄ）に一点鎖線で示すように、側板６２に外向きのダボ６５を膨出形成して、このダボ６５を補助カバー体１０ｂの内向きフランジ５５に引っ掛けることも可能である。   As a means for holding the auxiliary cover body 10b on the support bracket 59 so as not to fall off (instead of providing the claw piece 63 on the side plate 62) or in addition to this, FIG. 11 (e) shows a solid line and FIG. As indicated by the alternate long and short dash line in (d), it is possible to bulge and form an outward dowel 65 on the side plate 62 and hook the dowel 65 on the inward flange 55 of the auxiliary cover body 10b.

図１１（ｅ）に明示するように、反射板２６は軸方向から見て主カバー体１０ａの湾曲部１５に向けて凹状に凹んでおり、２つの長手側縁には補助カバー体１０ｂの横向き凸状５２に載る足片６５が一体に形成されており、かつ、足片６５には、補助カバー体１０ｂの係合爪条５３に外側から噛み合う係止爪６５ａが飛び飛びの状態で複数個形成されている。反射板２６のうち係止爪６５ａの箇所には、射出成形法で係止爪６５ａを形成するに当たって型抜きを容易ならしめるための抜き違い穴６６が空いている。   As clearly shown in FIG. 11 (e), the reflection plate 26 is concavely concaved toward the curved portion 15 of the main cover body 10a when viewed from the axial direction, and the two longitudinal side edges face the side of the auxiliary cover body 10b. A foot piece 65 mounted on the convex 52 is integrally formed, and a plurality of locking claws 65a that engage with the engaging claws 53 of the auxiliary cover body 10b from the outside are formed on the foot piece 65 in a jumping state. Has been. In the reflecting plate 26, a locking claw 65a is provided with a pull-out hole 66 for facilitating die cutting when the locking claw 65a is formed by an injection molding method.

補助カバー体１０ｂへの反射板２６の取付け手段としては、その厚さ方向に移動させて補助カバー体１０ｂに押し当てて、係止爪６５ａの箇所で足片６５を弾性変形させても良いし、或いは、反射板２６をその長手方向にスライドさせて係止爪６５ａを横向き凸条５２に嵌め合わせても良い。足片６５を飛び飛びの状態に形成することも可能である。   As a means for attaching the reflecting plate 26 to the auxiliary cover body 10b, the reflector 65 may be moved in the thickness direction and pressed against the auxiliary cover body 10b to elastically deform the foot piece 65 at the position of the locking claw 65a. Or you may slide the reflecting plate 26 to the longitudinal direction, and may engage the latching claw 65a with the horizontal protrusion 52. As shown in FIG. It is also possible to form the foot piece 65 in a flying state.

反射板２６には、回路基板１１をその長手側縁において保持するための吊支片６７と規制片６８とが一対ずつ形成されている。吊支片６７には、回路基板１１を脱落不能に保持する支持爪６７ａが飛び飛びの状態で形成されている。反射板２６のうち支持爪６７ａを設けた箇所には、支持爪６７ａを形成するための抜き違い穴６９が形成されている。従って、規制片６８は支持爪６７ａの箇所で分断している。吊支片６７と規制片６８とは、短い長さに設定して飛び飛びの状態で形成することも可能であるし、例えば反射板２６の両端寄り部位と中間との３箇所に形成するといったことも可能である。   The reflecting plate 26 is formed with a pair of a suspension piece 67 and a restriction piece 68 for holding the circuit board 11 at its longitudinal side edge. A support claw 67 a that holds the circuit board 11 so as not to drop off is formed on the hanging support piece 67 in a flying state. In the reflecting plate 26, a hole 69 for forming the support claw 67a is formed at a location where the support claw 67a is provided. Therefore, the restricting piece 68 is divided at the support claw 67a. The hanging support piece 67 and the regulating piece 68 can be set to a short length and can be formed in a jumping state, for example, formed at three locations near the both ends of the reflector 26 and in the middle. Is also possible.

第１実施形態と同様に、反射板２６にはＬＥＤを露出させるための貫通穴２７が空いている。反射板２６は、その厚さ方向に移動させて反射板２６の裏面に向けて押し当てて、反射板２６の吊支片６７を弾性変形させることとで反射板２６に取付けられる。   Similar to the first embodiment, the reflecting plate 26 has a through hole 27 for exposing the LED. The reflecting plate 26 is attached to the reflecting plate 26 by moving in the thickness direction and pressing the reflecting plate 26 toward the back surface of the reflecting plate 26 to elastically deform the suspension piece 67 of the reflecting plate 26.

照明灯１はエンドキャップ７１を有している。エンドキャップ７１は主カバー体１０ａに内側から嵌まる段違い突出部７１ａを有しており、また、外面には、ねじ１９の頭が嵌まる座繰り穴７２が形成されている。更に、補助カバー体１０ｂの取付け穴５４と連通する逃がし穴７３も空いている。   The illuminating lamp 1 has an end cap 71. The end cap 71 has a stepped protrusion 71a that fits into the main cover body 10a from the inside, and a counterbore hole 72 into which the head of the screw 19 fits is formed on the outer surface. Furthermore, an escape hole 73 communicating with the mounting hole 54 of the auxiliary cover body 10b is also provided.

図９に示すように、回路基板１１の両端部には一対の端子穴１１ａが空いており、この端子穴１１ａに、図９及び図１０（ａ）に示す第１中間コネクタ７４の端子ピン７５を差し込んだり、図１０（ｂ）に示すケーブル付きエンドコネクタ７６の端子ピン７５を差し込んだり、図１０（ｃ）に示す第２中間コネクタ７７の端子ピン７５を差し込んだりすることができる。   As shown in FIG. 9, a pair of terminal holes 11a are formed at both ends of the circuit board 11, and terminal pins 75 of the first intermediate connector 74 shown in FIGS. 9 and 10 (a) are formed in the terminal holes 11a. Can be inserted, the terminal pin 75 of the end connector with cable 76 shown in FIG. 10B can be inserted, or the terminal pin 75 of the second intermediate connector 77 shown in FIG. 10C can be inserted.

第１中間コネクタ７４は、エンドキャップ７１が装着されて１つの完成したユニットになっている照明灯１を連結する場合に使用する。従って、完成品としての照明灯１を幾つでも連結することができる。エンドキャップ７１には、第１中間コネクタ７４との干渉を回避するための凹所７８が形成されいる。また、補助カバー体１０ｂの両端部には、各コネクタ７４，７６，７７との干渉を回避するための切欠き７９が形成されている。   The first intermediate connector 74 is used when connecting the illuminating lamp 1, which has the end cap 71 attached thereto and forms one completed unit. Therefore, any number of the illuminating lamps 1 as finished products can be connected. The end cap 71 is formed with a recess 78 for avoiding interference with the first intermediate connector 74. In addition, notches 79 for avoiding interference with the connectors 74, 76, 77 are formed at both ends of the auxiliary cover body 10b.

１つの照明灯１のみを使用する場合は、回路基板１１の両端のうちの片側のみの端子穴１１ａにエンドコネクタ７６を接続する。複数の照明灯１を連結して使用する場合は、隣り合った回路基板１１は第１中間コネクタ７４で接続し、連続体の一端又は他端の１箇所にエンドコネクタ７６を接続する。また、１本ずつの主カバー体１０ａ及び補助カバー体１０ｂに複数の回路基板１１を直列配置することも可能であり、この場合は、図１０（ｃ）のように隣り合った回路基板１１は第２中間コネクタ７７で接続する。   When only one illuminating lamp 1 is used, the end connector 76 is connected to the terminal hole 11 a on only one side of the both ends of the circuit board 11. When a plurality of illuminating lamps 1 are connected and used, adjacent circuit boards 11 are connected by a first intermediate connector 74, and an end connector 76 is connected to one end or the other end of the continuous body. In addition, it is possible to arrange a plurality of circuit boards 11 in series on the main cover body 10a and the auxiliary cover body 10b one by one. In this case, the adjacent circuit boards 11 as shown in FIG. The second intermediate connector 77 is used for connection.

この第１２実施形態に係る照明灯１の組み立ては、まず反射板２６に回路基板１１をセットしておいてから、反射板２６を補助カバー体１０ｂにセットし、次いで補助カバー体１０ｂを主カバー体１０ａに差し込み又は強制嵌合にてセットするという手順で行われる。このように順次ユニット化しつつ組み立てが行われるため、組み立てを容易に行うことができる。   In assembling the illuminating lamp 1 according to the twelfth embodiment, the circuit board 11 is first set on the reflecting plate 26, the reflecting plate 26 is set on the auxiliary cover body 10b, and the auxiliary cover body 10b is then set on the main cover. It is performed by a procedure of inserting into the body 10a or setting by forced fitting. Since the assembly is performed while sequentially unitizing in this way, the assembly can be easily performed.

また、回路基板１１は反射板２６と補助カバー体１０ｂとを介して主カバー体１０ａに取付けられているため、主カバー体１０ａの横幅に対して回路基板１１の幅寸法を小さくできて光源ユニット１３の製造コストを抑制できる利点や、大きさが異なる照明灯１に１種類の光源ユニット１３を使用できるといった利点がある。本実施形態では拡散部は設けていないが、ＬＥＤ１２の存在が全く分からないように面発光させることができる。   Further, since the circuit board 11 is attached to the main cover body 10a via the reflecting plate 26 and the auxiliary cover body 10b, the width dimension of the circuit board 11 can be made smaller than the lateral width of the main cover body 10a, and the light source unit. There are advantages that the manufacturing cost of 13 can be suppressed and that one type of light source unit 13 can be used for the illumination lamps 1 having different sizes. In the present embodiment, no diffusing portion is provided, but surface emission can be performed so that the presence of the LED 12 is not known at all.

照明灯１のうち開口縁よりの２つの外面部には多数の溝条８０を形成しているが、これには、装飾的な効果と補助カバー体１０ｂ及び反射板２６を視認し難くする効果とがある（溝条８０の箇所で光が屈折することで補助カバー体１０ｂ及び反射板２６とが視認し難くなっている。）。もとより、溝条８０が存在しない平滑面とすることも可能である。   A number of grooves 80 are formed on the two outer surface portions of the illuminating lamp 1 from the opening edge. This has a decorative effect and an effect of making it difficult to visually recognize the auxiliary cover body 10b and the reflector 26. (It is difficult to visually recognize the auxiliary cover body 10b and the reflecting plate 26 because light is refracted at the groove 80). Of course, it is also possible to make it the smooth surface where the groove 80 does not exist.

照明灯１の大きさは任意に設定できる。例えば、全長を３００ｍｍ、主カバー体１０ａの幅寸法（図１１（ｂ）の場合であると左右長さ）を３２ｍｍ程度とすることが可能である。図１０（ｃ）のように連結すると、（回路基板１１の長さの整数倍＋エンドキャップ７１の露出幅寸法）の長さに設定できる。コネクタ７４，７６，７７を回路基板１１の端子穴１１ａへの嵌め込み方式にすると、構造が簡単になる利点がある。   The size of the illumination lamp 1 can be set arbitrarily. For example, the total length can be 300 mm, and the width dimension of the main cover body 10a (the length in the left-right direction in the case of FIG. 11B) can be about 32 mm. When connected as shown in FIG. 10C, the length can be set to (integer multiple of the length of the circuit board 11 + exposed width dimension of the end cap 71). When the connectors 74, 76, 77 are fitted into the terminal holes 11a of the circuit board 11, there is an advantage that the structure is simplified.

(7).第１２実施形態のバリエーション
主カバー体１０ａの断面形状は任意に設定できる。例えば図１１（ｂ）に二点鎖線で示すように丸みがない角形とすることが可能である。断面台状や山形を採用することも可能である。 (7). Variation of 12th Embodiment The cross-sectional shape of the main cover body 10a can be arbitrarily set. For example, as shown by a two-dot chain line in FIG. It is also possible to adopt a trapezoidal cross section or a mountain shape.

図１２では照明灯１の設置構造の別例を示している。この例は補助カバー体１０ｂを施行場所にねじ６１で直接に固定できるようにしたもので、そこで、補助カバー体１０ｂの端部は照明灯１や光源ユニット１３や反射板２６の端面の外側に露出しており、露出部に取付け穴８１を空けている。また、この例では、主カバー体１０ａと光源ユニット１３と反射板２６との位置決めのためエンドストッパー８２と、補助カバー体１０ｂの露出部を覆う補助キャップ８３とが使用されている。   FIG. 12 shows another example of the installation structure of the illumination lamp 1. In this example, the auxiliary cover body 10b can be directly fixed to the enforcement place with a screw 61, and the end of the auxiliary cover body 10b is located outside the end face of the illuminating lamp 1, the light source unit 13, and the reflector 26. It is exposed and has a mounting hole 81 in the exposed portion. In this example, an end stopper 82 and an auxiliary cap 83 that covers the exposed portion of the auxiliary cover body 10b are used for positioning the main cover body 10a, the light source unit 13, and the reflector 26.

エンドストッパー８２は、補助カバー体１０ｂの露出部に重なると共に主カバー体１０ａの端面を覆うように底片と起立片とを有する正断面略Ｌ形になっており、起立片に、主カバー体１０ａに内側から嵌まる内向き段違い突出部８２ａと、補助キャップ８３に内側から嵌まる外向き段違い突出部８２ｂとが形成されている。エンドストッパー８２の底片にもねじ６１が嵌まる取付け穴８１が空いている。従って、エンドストッパー８２と補助カバー体１０ｂとはねじ６１で施行場所に共締めされる。   The end stopper 82 has a substantially L-shaped cross section having a bottom piece and an upright piece so as to cover the end surface of the main cover body 10a while overlapping the exposed portion of the auxiliary cover body 10b. An inwardly protruding portion 82a that fits from the inside to the inside, and an outwardly protruding portion 82b that fits from the inside to the auxiliary cap 83 are formed. A mounting hole 81 into which the screw 61 is fitted is also formed in the bottom piece of the end stopper 82. Therefore, the end stopper 82 and the auxiliary cover body 10b are fastened together with the screw 61 at the enforcement place.

補助キャップ８３は外周板と端板とを有しており、内周面には補助カバー体１０ｂの係合溝５７に嵌まる係合突起８４を設けている。補助キャップ８３で覆った状態を図１２（ｅ）に示している。   The auxiliary cap 83 has an outer peripheral plate and an end plate, and an engagement protrusion 84 that fits into the engagement groove 57 of the auxiliary cover body 10b is provided on the inner peripheral surface. The state covered with the auxiliary cap 83 is shown in FIG.

(8).その他
本願発明の実施形態を説明してきたが、本願発明は上記の実施形態の他にも様々に具体化できる。例えば反射板にＬＥＤのような発光素子をマウントして、反射板と回路基板とを一体化することも可能である。或いは、実施形態における補助カバー体（ベース体）に回路基板を固定又は接着して、補助カバー体を主カバー体に嵌め込むといったことも可能である。 (8). Other Embodiments of the present invention have been described, but the present invention can be embodied in various ways other than the above-described embodiments. For example, it is possible to mount a light emitting element such as an LED on the reflection plate, and integrate the reflection plate and the circuit board. Alternatively, the circuit board may be fixed or bonded to the auxiliary cover body (base body) in the embodiment, and the auxiliary cover body may be fitted into the main cover body.

回路基板を反射板でも補助カバー体でもない他の保持部材に取付けて、この保持部材をカバー部材に嵌め込み装着したり、保持部材を更に反射板や補助カバー体に取付けるといったことも可能である。   It is also possible to attach the circuit board to another holding member that is neither a reflection plate nor an auxiliary cover body, and to fit the holding member into the cover member and attach the holding member to the reflection plate or the auxiliary cover body.

本願発明は照明灯に適用してその有用性を発揮できるものであり、従って産業上利用できる。   The present invention can be applied to an illuminating lamp to exhibit its usefulness, and thus can be used industrially.
