Description

本発明の実施形態は、フレキシブル配線基板に発光素子が実装された発光モジュールを用いた発光ユニット、この発光ユニットを用いた直管形ランプおよび照明装置に関する。   Embodiments described herein relate generally to a light emitting unit using a light emitting module in which a light emitting element is mounted on a flexible wiring board, a straight tube lamp using the light emitting unit, and an illumination device.

従来、発光ユニットを用いた例えば直管形ランプや長尺な照明器具等がある。発光ユニットには、基板に発光素子を実装した発光モジュールを基台に保持した構造がある。発光モジュールは、比較的強固な基板に発光素子を実装するのが一般的であったが、フレキシブル配線基板に発光素子を実装した発光モジュールが開発されている。   Conventionally, there are, for example, a straight tube lamp and a long luminaire using a light emitting unit. The light emitting unit has a structure in which a light emitting module in which a light emitting element is mounted on a substrate is held on a base. In general, a light emitting module has a light emitting element mounted on a relatively strong substrate. However, a light emitting module in which a light emitting element is mounted on a flexible wiring board has been developed.

フレキシブル配線基板の場合、フレキシブル配線基板を部分的に基台に保持したのではフレキシブル配線基板と基台との密着性が均一に得られず、放熱性が影響するため、フレキシブル配線基板の全長に亘って基台に保持する構造が採られている。   In the case of a flexible wiring board, if the flexible wiring board is partially held on the base, the adhesion between the flexible wiring board and the base cannot be obtained uniformly, and heat dissipation is affected. A structure that is held on the base is adopted.

例えば、基台を断面半環状に形成し、この基台の内面中央にフレキシブル配線基板の発光素子が実装された表面中央に対して反対側である裏面中央が接触する突部が突設され、基台の内面両側部にフレキシブル配線基板の両側部の先端が当接する引掛り部が突設されている。そして、フレキシブル配線基板が幅方向に全体的に湾曲されて、フレキシブル配線基板の裏面中央が突部に接触し、フレキシブル配線基板の両側部の先端が引掛り部に当接した状態で、フレキシブル配線基板が基台に保持されている。フレキシブル配線基板の両側部の先端が引掛り部に当接することにより、フレキシブル配線基板の裏面中央が突部に押し付けられている。また、基台とフレキシブル配線基板とを組み立てる場合は、基台の一端側からフレキシブル配線基板を挿入することで行っている。   For example, the base is formed in a semicircular cross section, and a protrusion is provided in the center of the inner surface of the base that is in contact with the center of the back surface opposite to the center of the surface on which the light emitting element of the flexible wiring board is mounted. A hooking portion is provided on both sides of the inner surface of the base so that the tips of the both sides of the flexible wiring board come into contact with each other. The flexible wiring board is bent in the width direction as a whole, the center of the back surface of the flexible wiring board is in contact with the protrusion, and the flexible wiring board is in contact with the hooks at both ends. The substrate is held on the base. The center of the back surface of the flexible wiring board is pressed against the protrusion by the tips of both sides of the flexible wiring board being in contact with the hooking portion. Moreover, when assembling the base and the flexible wiring board, the flexible wiring board is inserted from one end side of the base.

特開２０１２-１１４０３４号公報JP 2012-114034 A

しかしながら、フレキシブル配線基板が幅方向に全体的に湾曲されて、フレキシブル配線基板の両側部の先端が引掛り部に当接し、フレキシブル配線基板の裏面中央を突部に接触させる構造であるため、フレキシブル配線基板が両側の引掛り部間で突っ張った状態となって、フレキシブル配線基板の両側部の先端が引掛り部に圧接する。   However, since the flexible wiring board is entirely curved in the width direction, the tips of the both sides of the flexible wiring board are in contact with the hooking part, and the center of the back surface of the flexible wiring board is in contact with the protruding part. The wiring board is in a state of being stretched between the hooking parts on both sides, and the tips of the both side parts of the flexible wiring board are in pressure contact with the hooking parts.

そのため、基台の一端側からフレキシブル配線基板を挿入して組み立てる際、基台の引掛り部とフレキシブル配線基板の両側部の先端との摺動抵抗が大きくかつ挿入が引っ掛かり易く、基台へのフレキシブル配線基板の挿入量が増加するほど、および基台の長手方向の寸法が長いほど、基台にフレキシブル配線基板を挿入しずらくなり、組立作業性が悪い不都合がある。   Therefore, when inserting and assembling the flexible wiring board from one end of the base, the sliding resistance between the hooking part of the base and the tip of the both sides of the flexible wiring board is large and the insertion is easy to be caught. As the amount of insertion of the flexible wiring board increases and the length in the longitudinal direction of the base becomes longer, it becomes more difficult to insert the flexible wiring board into the base, and there is a disadvantage that the assembly workability is poor.

さらに、フレキシブル配線基板の幅寸法と基台の寸法誤差との影響により、基台にフレキシブル配線基板をより挿入しずらくなったり、あるいは、突起に対するフレキシブル配線基板の裏面中央の当接力が弱くなって放熱性が低下する不具合がある。   Furthermore, due to the influence of the width dimension of the flexible wiring board and the dimensional error of the base, it becomes more difficult to insert the flexible wiring board into the base, or the contact force at the center of the back surface of the flexible wiring board to the protrusion becomes weak. There is a problem that heat dissipation is reduced.

本発明が解決しようとする課題は、組立作業性を向上でき、フレキシブル配線基板から基台への安定した放熱性を得ることができる発光ユニット、直管形ランプおよび照明装置を提供することである。   The problem to be solved by the present invention is to provide a light emitting unit, a straight tube lamp, and an illuminating device that can improve assembly workability and can obtain stable heat dissipation from a flexible wiring board to a base. .

実施形態の発光ユニットは、発光モジュールおよび基台を備える。発光モジュールは、フレキシブル配線基板の表面に発光素子が実装される。基台は、フレキシブル配線基板の裏面が接触する平面状の基板搭載面、およびこの基板搭載面に接触するフレキシブル配線基板の両側部が配置される溝部を設けた両側の保持部を有する。溝部の最深部にフレキシブル配線基板の両側部の先端が当接しない。保持部により、フレキシブル配線基板の両側部を湾曲させて、フレキシブル配線基板の裏面が基板搭載面に沿って接触する状態にフレキシブル配線基板を保持する。   The light emitting unit of the embodiment includes a light emitting module and a base. In the light emitting module, a light emitting element is mounted on the surface of a flexible wiring board. The base has a planar substrate mounting surface with which the back surface of the flexible wiring substrate contacts, and holding portions on both sides provided with grooves in which both sides of the flexible wiring substrate in contact with the substrate mounting surface are disposed. The tips of both sides of the flexible wiring board do not contact the deepest part of the groove. Both sides of the flexible wiring board are bent by the holding part, and the flexible wiring board is held in a state where the back surface of the flexible wiring board is in contact with the board mounting surface.

本発明によれば、溝部の最深部にフレキシブル配線基板の両側部の先端を当接させず、保持部により、フレキシブル配線基板の両側部を湾曲させ、フレキシブル配線基板の裏面が基板搭載面に沿って接触する状態にフレキシブル配線基板を保持するため、基台にフレキシブル配線基板を容易に挿入することが可能となって組立作業性を向上でき、フレキシブル配線基板から基台への安定した放熱性が得られることが期待できる。   According to the present invention, the ends of both sides of the flexible wiring board are not brought into contact with the deepest part of the groove part, but the both sides of the flexible wiring board are curved by the holding part, and the back surface of the flexible wiring board is along the board mounting surface. Since the flexible wiring board is held in contact with each other, the flexible wiring board can be easily inserted into the base, improving the assembly workability, and providing stable heat dissipation from the flexible wiring board to the base. It can be expected to be obtained.

以下、第１の実施形態を、図１ないし図３を参照して説明する。   Hereinafter, a first embodiment will be described with reference to FIGS. 1 to 3.

図３に示すように、照明装置10は、長尺な直管形ランプ11を使用するものであり、長尺な器具本体12、この器具本体12の長手方向の両端に配置されるソケット13，14、および器具本体12内に配設される電源回路15等を備えている。   As shown in FIG. 3, the lighting device 10 uses a long straight tube lamp 11, and includes a long instrument body 12, sockets 13 disposed at both ends in the longitudinal direction of the instrument body 12, 14, and a power supply circuit 15 disposed in the instrument body 12.

そして、図１および図２に、直管形ランプ11を示す。直管形ランプ11は、直管カバー20、この直管カバー20内に挿入配置される発光ユニット21、直管カバー20および発光ユニット21の両端に配設される口金22，23を備えている。   1 and 2 show a straight tube lamp 11. The straight tube lamp 11 includes a straight tube cover 20, a light emitting unit 21 inserted and disposed in the straight tube cover 20, a straight tube cover 20, and caps 22 and 23 disposed at both ends of the light emitting unit 21. .

直管カバー20は、透光性の樹脂材料で形成されている。樹脂材料には、例えばポリカーボネート樹脂が用いられる。樹脂材料には光拡散材を含有してもよい。直管カバー20は、長手方向に同一の円筒状に形成されている。例えば押出成形によって直管カバー20が形成されている。また、直管カバー20の周面の略半分近くの領域が、発光ユニット21からの光を透光する透光領域26に形成されている。直管カバー20の少なくとも透光領域26が透光性を有していれば、他の領域は透光性を有していなくてもよい。   The straight pipe cover 20 is formed of a translucent resin material. For example, polycarbonate resin is used as the resin material. The resin material may contain a light diffusing material. The straight pipe cover 20 is formed in the same cylindrical shape in the longitudinal direction. For example, the straight pipe cover 20 is formed by extrusion molding. Further, a region near approximately half of the peripheral surface of the straight pipe cover 20 is formed in a light transmitting region 26 that transmits light from the light emitting unit 21. As long as at least the translucent region 26 of the straight tube cover 20 has translucency, the other regions may not have translucency.

直管カバー20は、外面が円形状に形成され、内面が所定の形状に形成されている。直管カバー20の内面には、透光領域26の中央から両側に向けて肉厚が徐々に厚くなるように形成され、その両側部分には発光ユニット21（基台）を保持する保持溝27が長手方向全域に亘って形成されている。さらに、直管カバー20の内面には、透光領域26に対して反対側に、一対の略Ｌ字形の突部28が互いに対向して突設され、これら突部28間に発光ユニット21（基台）を保持する保持溝29が長手方向の全域に亘って形成されている。   The straight pipe cover 20 has an outer surface formed in a circular shape and an inner surface formed in a predetermined shape. The inner surface of the straight tube cover 20 is formed so that the thickness gradually increases from the center of the light transmitting region 26 toward both sides, and holding grooves 27 for holding the light emitting unit 21 (base) are formed on both side portions thereof. Is formed over the entire longitudinal direction. Further, a pair of substantially L-shaped protrusions 28 are provided on the inner surface of the straight tube cover 20 on the opposite side to the light-transmitting region 26 so as to face each other, and the light emitting unit 21 ( A holding groove 29 for holding the base) is formed over the entire area in the longitudinal direction.

発光ユニット21は、発光モジュール32、およびこの発光モジュール32を保持する基台33を備えている。   The light emitting unit 21 includes a light emitting module 32 and a base 33 that holds the light emitting module 32.

発光モジュール32は、長尺な帯状のフレキシブル配線基板35、およびこのフレキシブル配線基板35の表面35aの幅方向中央に実装された複数の発光素子36を備えている。   The light emitting module 32 includes a long strip-shaped flexible wiring board 35 and a plurality of light emitting elements 36 mounted at the center in the width direction of the surface 35a of the flexible wiring board 35.

フレキシブル配線基板35は、フィルム状の絶縁材と配線パターンを積層して構成されている。配線パターンに複数の発光素子36が電気的に接続され、配線パターンにより複数の発光素子36が例えば直列に電気的に接続されている。なお、フレキシブル配線基板35の表面35aには、光の反射率が高い高反射膜を形成してもよい。   The flexible wiring board 35 is configured by laminating a film-like insulating material and a wiring pattern. A plurality of light emitting elements 36 are electrically connected to the wiring pattern, and the plurality of light emitting elements 36 are electrically connected, for example, in series by the wiring pattern. A highly reflective film having a high light reflectance may be formed on the surface 35a of the flexible wiring board 35.

発光素子36は、例えばＬＥＤや有機ＥＬ等が用いられている。本実施形態では、ＬＥＤが用いられ、複数のＬＥＤがフレキシブル配線基板35の表面35aの幅方向中央で長手方向に沿って所定の間隔をあけて実装されている。   As the light emitting element 36, for example, an LED or an organic EL is used. In the present embodiment, LEDs are used, and a plurality of LEDs are mounted at predetermined intervals along the longitudinal direction at the center in the width direction of the surface 35a of the flexible wiring board 35.

発光モジュール32は、フレキシブル配線基板35の幅方向の両側部領域35cの強度が幅方向の中央部領域35dの強度よりも低くなるように構成してもよい。例えば、フレキシブル配線基板35の中央部領域35dのみに配線パターンを形成したり、フレキシブル配線基板35の表面35aの中央部領域35dに高反射膜を形成することにより、フレキシブル配線基板35の両側部領域35cの強度が中央部領域35dの強度よりも低くなるように構成できる。あるいは、フレキシブル配線基板35の両側部領域35cの厚みを中央部領域35dの厚みよりも薄くしたり、フレキシブル配線基板35の両側部領域35cに孔をあけることにより、フレキシブル配線基板35の両側部領域35cの強度が中央部領域35dの強度よりも低くなるように構成できる。なお、フレキシブル配線基板35の中央部領域35dの幅寸法は、フレキシブル配線基板35の両側部領域35cのそれぞれの幅寸法より広い。   The light emitting module 32 may be configured such that the strength of both side regions 35c in the width direction of the flexible wiring board 35 is lower than the strength of the central region 35d in the width direction. For example, by forming a wiring pattern only in the central region 35d of the flexible wiring board 35 or by forming a highly reflective film in the central region 35d of the surface 35a of the flexible wiring substrate 35, both side regions of the flexible wiring substrate 35 It can be configured such that the strength of 35c is lower than the strength of the central region 35d. Alternatively, both side regions of the flexible wiring board 35 can be obtained by making the thickness of the both side regions 35c of the flexible wiring board 35 thinner than the thickness of the central region 35d or by making holes in the both side regions 35c of the flexible wiring board 35. It can be configured such that the strength of 35c is lower than the strength of the central region 35d. The width dimension of the central area 35d of the flexible wiring board 35 is wider than the width dimension of each of the both side areas 35c of the flexible wiring board 35.

基台33は、金属材料で形成されている。金属材料としては、例えばアルミニウム等が用いられる。基台33は、長手方向に同一形状に一体に形成されている。例えば押出成形によって基台33が形成されている。そして、基台33は、基板搭載部38、この基板搭載部38の両側に形成された保持部39、および基板搭載部38を支える土台部40を備えている。   The base 33 is made of a metal material. As the metal material, for example, aluminum or the like is used. The base 33 is integrally formed in the same shape in the longitudinal direction. For example, the base 33 is formed by extrusion molding. The base 33 includes a substrate mounting portion 38, holding portions 39 formed on both sides of the substrate mounting portion 38, and a base portion 40 that supports the substrate mounting portion 38.

基板搭載部38には、フレキシブル配線基板35の裏面35bの中央部領域35dが接触する平面状の基板搭載面42が形成されている。   The substrate mounting portion 38 is formed with a planar substrate mounting surface 42 that contacts the central region 35d of the back surface 35b of the flexible wiring substrate 35.

両側の保持部39は、基板搭載部38の基板搭載面42よりも突出されている。両側の保持部39には、フレキシブル配線基板35の両側部35eが配置される溝部44が形成されている。保持部39には、溝部44を介して基板搭載面42に対向する爪部45が突出形成されている。なお、直管カバー20の透光領域26に対向される爪部45の表面側は反射面に形成されている。   The holding parts 39 on both sides protrude from the board mounting surface 42 of the board mounting part 38. Groove portions 44 in which both side portions 35e of the flexible wiring board 35 are disposed are formed in the holding portions 39 on both sides. A claw portion 45 is formed on the holding portion 39 so as to protrude from the substrate mounting surface 42 through the groove portion 44. Note that the surface side of the claw portion 45 facing the translucent region 26 of the straight tube cover 20 is formed as a reflective surface.

両側の溝部44は、互いに対向するとともに基板搭載面42に対して斜めに対向するように形成されている。両側の保持部39により、溝部44に配置されたフレキシブル配線基板35の両側部35eを局所的に湾曲させ、フレキシブル配線基板35の両側部35eに小さい曲率の曲げ部35fを形成する。フレキシブル配線基板35の両側部35eに局所的に曲げ部35fを形成することにより、フレキシブル配線基板35の中央部領域35dの裏面35bが基板搭載面42に沿って接触する状態にフレキシブル配線基板35を保持する。   The groove portions 44 on both sides are formed so as to face each other and obliquely face the substrate mounting surface 42. The holding portions 39 on both sides locally curve both side portions 35e of the flexible wiring board 35 disposed in the groove portion 44, thereby forming bent portions 35f having small curvatures on both side portions 35e of the flexible wiring board 35. By forming bent portions 35f locally on both side portions 35e of the flexible wiring board 35, the flexible wiring board 35 is brought into contact with the back surface 35b of the central region 35d of the flexible wiring board 35 along the board mounting surface 42. Hold.

基台33の幅方向中心にフレキシブル配線基板35が組み込まれている場合には、フレキシブル配線基板35の両側部35eの先端が保持部39の溝部44の最深部44aから離れていてその最深部44aには当接しない関係を有する。基台33の幅方向中心に対して一側にフレキシブル配線基板35が片寄って組み込まれている場合でも、フレキシブル配線基板35の両側部35eの先端の少なくとも一方が保持部39の溝部44の最深部44aから離れていてその最深部44aには当接しない関係を有する。言い換えれば、フレキシブル配線基板35の両側部35eの先端と溝部44の最深部44aとの間には間隙を有する。あるいは、両側の溝部44の最深部44a間の最大幅寸法が、両側の溝部44に配置されたフレキシブル配線基板35の両側部35eの先端間の幅寸法よりも広い関係を有している。   When the flexible wiring board 35 is incorporated in the center of the base 33 in the width direction, the tips of both side portions 35e of the flexible wiring board 35 are separated from the deepest portion 44a of the groove portion 44 of the holding portion 39, and the deepest portion 44a Have a non-contact relationship. Even when the flexible wiring board 35 is assembled on one side with respect to the center in the width direction of the base 33, at least one of the front ends of both side portions 35e of the flexible wiring board 35 is the deepest portion of the groove portion 44 of the holding portion 39. It has a relationship of being away from 44a and not contacting the deepest portion 44a. In other words, there is a gap between the tips of the side portions 35e of the flexible wiring board 35 and the deepest portion 44a of the groove portion 44. Alternatively, the maximum width dimension between the deepest portions 44a of the groove portions 44 on both sides has a relationship wider than the width dimension between the tips of the both side portions 35e of the flexible wiring board 35 disposed in the groove portions 44 on both sides.

次に、本実施形態の作用を説明する。   Next, the operation of this embodiment will be described.

発光ユニット21を組み立てるには、基台33の一端側から発光モジュール32を挿入する。   In order to assemble the light emitting unit 21, the light emitting module 32 is inserted from one end side of the base 33.

すなわち、フレキシブル配線基板35の端部の中央部領域35dを基台33の基板搭載面42上に挿入するとともに、フレキシブル配線基板35の端部の両側部35eを両側の保持部39の溝部44に挿入する。   That is, the central region 35d of the end portion of the flexible wiring board 35 is inserted on the substrate mounting surface 42 of the base 33, and both side portions 35e of the end portion of the flexible wiring substrate 35 are formed into the groove portions 44 of the holding portions 39 on both sides. insert.

このとき、フレキシブル配線基板35の端部の両側部分を先細り状にカットしておくことにより、フレキシブル配線基板35の中央部領域35dを基台33の基板搭載面42上に挿入すれば、フレキシブル配線基板35の両側部35eが両側の保持部39の溝部44に自動的に挿入されやすくなり、フレキシブル配線基板35の端部の挿入操作を容易にすることができる。   At this time, by cutting both side portions of the end portion of the flexible wiring board 35 in a tapered shape, if the central region 35d of the flexible wiring board 35 is inserted on the board mounting surface 42 of the base 33, the flexible wiring board 35 Both side portions 35e of the substrate 35 are easily inserted into the groove portions 44 of the holding portions 39 on both sides, and the insertion operation of the end portions of the flexible wiring substrate 35 can be facilitated.

フレキシブル配線基板35の端部を基台33に挿入したら、そのままフレキシブル配線基板35を基台33に沿って摺動させ、フレキシブル配線基板35を基台33の所定位置に配置する。   When the end portion of the flexible wiring board 35 is inserted into the base 33, the flexible wiring board 35 is slid along the base 33 as it is, and the flexible wiring board 35 is disposed at a predetermined position on the base 33.

このとき、保持部39により、フレキシブル配線基板35の両側部35eを湾曲させ、フレキシブル配線基板35の裏面35bが基板搭載面42に沿って接触する状態にフレキシブル配線基板35を保持するものの、フレキシブル配線基板35の両側部35eの先端が両側の溝部44の最深部44aに当接しない構造であるため、フレキシブル配線基板35が両側の保持部39間で突っ張った状態となることがなく、保持部39に対するフレキシブル配線基板35の両側部35eの摺動抵抗が低いとともに、フレキシブル配線基板35の両側部35eが保持部39に引っ掛かりにくく、フレキシブル配線基板35を基台33内の所定位置まで容易に摺動させることができる。   At this time, both sides 35e of the flexible wiring board 35 are bent by the holding portion 39, and the flexible wiring board 35 is held in a state where the back surface 35b of the flexible wiring board 35 is in contact with the board mounting surface 42. Since the front ends of the side portions 35e of the substrate 35 do not contact the deepest portions 44a of the groove portions 44 on both sides, the flexible wiring substrate 35 does not stretch between the holding portions 39 on both sides, and the holding portions 39 The sliding resistance of both side portions 35e of the flexible wiring board 35 is low, and the both side portions 35e of the flexible wiring board 35 are not easily caught by the holding portion 39, so that the flexible wiring board 35 can easily slide to a predetermined position in the base 33. Can be made.

フレキシブル配線基板35を基台33内の所定位置に配置した状態では、保持部39により、フレキシブル配線基板35の両側部35eを湾曲させ、フレキシブル配線基板35の裏面35bが基板搭載面42に沿って接触する状態にフレキシブル配線基板35を保持する。   In a state where the flexible wiring board 35 is disposed at a predetermined position in the base 33, the holding portion 39 causes the both side portions 35e of the flexible wiring board 35 to bend so that the back surface 35b of the flexible wiring board 35 extends along the board mounting surface 42. The flexible wiring board 35 is held in contact.

このように、本実施形態の発光ユニット21によれば、両側の溝部44の最深部44aにフレキシブル配線基板35の両側部35eの先端が当接せず、保持部39により、フレキシブル配線基板35の両側部35eを湾曲させ、フレキシブル配線基板35の裏面35bが基板搭載面42に沿って接触する状態にフレキシブル配線基板35を保持するため、基台33にフレキシブル配線基板35を容易に挿入することが可能となって組立作業性を向上でき、さらに、フレキシブル配線基板35から基台33への安定した放熱性を得ることができる。   Thus, according to the light emitting unit 21 of the present embodiment, the tips of the both side portions 35e of the flexible wiring board 35 do not come into contact with the deepest portions 44a of the groove portions 44 on both sides, and the holding portion 39 allows the flexible wiring board 35 to The flexible wiring board 35 can be easily inserted into the base 33 in order to hold the flexible wiring board 35 in a state in which both side portions 35e are curved and the back surface 35b of the flexible wiring board 35 is in contact with the board mounting surface 42. As a result, assembly workability can be improved, and stable heat dissipation from the flexible wiring board 35 to the base 33 can be obtained.

また、基板搭載面42に沿って接触するフレキシブル配線基板35の中央部領域35dの幅寸法が、保持部39によって湾曲されるフレキシブル配線基板35の両側部領域35cの幅寸法よりも広い。このことは、両側の保持部39により、溝部44に配置されたフレキシブル配線基板35の両側部35eを局所的に湾曲させ、フレキシブル配線基板35の両側部35eに小さい曲率の曲げ部35fを形成することになる。このように、フレキシブル配線基板35の両側部35eに局所的に曲げ部35fを形成することにより、フレキシブル配線基板35の中央部領域35dの裏面35bが基板搭載面42に沿って接触する状態にフレキシブル配線基板35を保持することができる。   In addition, the width dimension of the central area 35d of the flexible wiring board 35 that contacts along the board mounting surface 42 is wider than the width dimension of both side areas 35c of the flexible wiring board 35 curved by the holding portion 39. This means that the holding portions 39 on both sides cause the side portions 35e of the flexible wiring board 35 disposed in the groove portion 44 to be locally bent, and the bent portions 35f having a small curvature are formed on the both side portions 35e of the flexible wiring substrate 35. It will be. In this way, by forming the bent portions 35f locally on both side portions 35e of the flexible wiring board 35, the back surface 35b of the central region 35d of the flexible wiring board 35 can be flexibly brought into contact with the board mounting surface 42. The wiring board 35 can be held.

また、保持部39は、基板搭載面42に対して立ち上がる立上り面46、およびこの立上り面46と基板搭載面42との間で基板搭載面42に対して窪む窪み部47を有している。そのため、基台33には、フレキシブル配線基板35でなく、比較的強固なハード基板を用いた発光モジュールをも組み合わせることができ、基台33を共通化できる。立上り面46でハード基板の幅方向の両側位置を規制し、窪み部47にハード基板の裏面両側部を配置してハード基板の中央部領域を基台33に密着可能とするように構成されている。   The holding portion 39 has a rising surface 46 that rises with respect to the substrate mounting surface 42, and a recess 47 that is recessed with respect to the substrate mounting surface 42 between the rising surface 46 and the substrate mounting surface 42. . Therefore, the base 33 can be combined with not only the flexible wiring board 35 but also a light emitting module using a relatively strong hard board, and the base 33 can be shared. The rising surface 46 is configured to regulate both side positions in the width direction of the hard board, and to arrange the both sides of the back side of the hard board in the recessed part 47 so that the central area of the hard board can be in close contact with the base 33. Yes.

また、直管形ランプ11を組み立てるには、直管カバー20内に発光ユニット21を挿入し、口金22とフレキシブル配線基板35とを電気的に接続し、直管カバー20の両端に口金22，23を被着し、基台33に口金22，23をねじ止めする。   To assemble the straight tube lamp 11, the light emitting unit 21 is inserted into the straight tube cover 20, the base 22 and the flexible wiring board 35 are electrically connected, and the base 22, 23 is attached, and the bases 22 and 23 are screwed to the base 33.

そして、図３に示すように、直管形ランプ11の口金22，23が照明装置10のソケット13，14に装着される。   As shown in FIG. 3, the caps 22 and 23 of the straight tube lamp 11 are attached to the sockets 13 and 14 of the lighting device 10.

電源回路15からソケット13を通じて直管形ランプ11に点灯電力を供給することにより、複数の発光素子36が点灯する。複数の発光素子36が発生する光は直管カバー20の透光領域26に入射し、透光領域26内で拡散されて透光領域26を透過し、照明空間に照射される。   By supplying lighting power from the power supply circuit 15 to the straight tube lamp 11 through the socket 13, the plurality of light emitting elements 36 are turned on. Light generated by the plurality of light emitting elements 36 enters the light transmitting region 26 of the straight tube cover 20, is diffused in the light transmitting region 26, passes through the light transmitting region 26, and is irradiated to the illumination space.

複数の発光素子36が点灯時に発生する熱は、フレキシブル配線基板35から基台33に伝達され、基台33から直管カバー20や口金22，23に伝達されて放熱される。   Heat generated when the plurality of light emitting elements 36 are turned on is transmitted from the flexible wiring board 35 to the base 33, and is transmitted from the base 33 to the straight tube cover 20 and the caps 22 and 23 to be radiated.

このとき、保持部39により、フレキシブル配線基板35の両側部35eを湾曲させ、フレキシブル配線基板35の裏面35bが基板搭載面42に沿って接触する状態にフレキシブル配線基板35を保持しているため、発光素子36が発生する熱をフレキシブル配線基板35を通じて基台33に効率よく熱伝導することができ、発光素子36の高い放熱性能を確保することができる。   At this time, by holding the flexible wiring board 35 in a state in which both sides 35e of the flexible wiring board 35 are curved by the holding portion 39 and the back surface 35b of the flexible wiring board 35 is in contact with the board mounting surface 42. The heat generated by the light emitting element 36 can be efficiently conducted to the base 33 through the flexible wiring board 35, and the high heat dissipation performance of the light emitting element 36 can be ensured.
