Description

本発明は、複数の発光ダイオードが長手方向に沿って列状に設けられて天井や壁の取付面に取り付けられる長尺状のＬＥＤ灯具に関するものである。 The present invention relates to a long LED lamp in which a plurality of light emitting diodes are provided in a row along the longitudinal direction and attached to a mounting surface of a ceiling or a wall.

長尺状のＬＥＤ灯具として、例えば、下記特許文献１の意匠登録公報（意匠に係る物品「照明器具用ケーシング」）の参考図に開示されるものがある。このＬＥＤ灯具は、鉄道車両や航空機、自動車等の客室内に設置されるもので、例えば、同文献の「客室内に設置した状態を示す参考断面図」に示されるように、客室の天井に取り付けられる。 As a long LED lamp, for example, there is one disclosed in a reference diagram of a design registration gazette (article “illumination casing” relating to a design) of Patent Document 1 below. This LED lamp is installed in a guest room such as a railway vehicle, an aircraft, an automobile, etc. For example, as shown in “Reference sectional view showing a state installed in a guest room” of the same document, It is attached.

意匠登録第１４５８４４０号公報（使用状態を示すＡ−Ａ線参考拡大断面図）Design registration No. 1458440 gazette (AA line reference enlarged sectional view showing a use state)

ところで、上記特許文献１に開示されるＬＥＤ灯具は、そのケーシングが「同一断面形で長尺に延びており、傘状の断面形の中央部から両側に広がる両側部は、それぞれ中央部より左右対称に水平に延出した後、徐々に下方に向かって湾曲した円弧形断面に形成されて」いる。また、「前記中央部から下方に垂下する光源等の一対の取付部は、左右対称に下方に向かい鉛直よりやや上向きの角度で互いに離隔するように垂下し、それぞれの下端よりさらに湾曲した円弧形断面の部位が直角に満たない角度で交わるように延出している」（同文献；意匠に係る物品の説明の欄）。 By the way, the LED lamp disclosed in the above-mentioned patent document 1 has a casing extending “long in the same cross-sectional shape, and both side portions extending from the central portion of the umbrella-shaped cross-sectional shape to both sides are left and right from the central portion, respectively. After extending horizontally symmetrically, it is formed into an arc-shaped cross section that curves gradually downward. In addition, “a pair of attachment parts such as a light source that hangs downward from the central portion hangs so as to be symmetrically downward and away from each other at an angle slightly upward from the vertical, and are further curved from the respective lower ends. It extends so that the sections of the cross-section intersect at an angle that is less than a right angle "(ibid .; column for the description of the article according to the design).

即ち、このＬＥＤ灯具は、上記参考図からわかるように、中央部において垂下する基板（２）の取付部やその他の部分が、ＬＥＤ（１）の発光を反射する反射面（４）と一体に形成されている（括弧内の数字は、同文献において用いられている符号に対応する）。そのため、例えば、反射効率を向上させるために反射面（４）を白色に、それ以外の部分を車両内や機内のデザイン等に合わせた色に、ケーシングを塗装する場合、マスキングテープ等を使用した精緻な塗り分け作業が必要になる。したがって、塗り分け作業が容易ではない。 That is, as can be seen from the above reference drawing, the LED lamp has an attachment portion of the substrate (2) that hangs down at the central portion and other portions integrated with the reflective surface (4) that reflects the light emission of the LED (1). (The numbers in parentheses correspond to the symbols used in the literature). Therefore, for example, in order to improve the reflection efficiency, masking tape or the like was used when the casing was painted with the reflective surface (4) white and the other parts in a color that matches the design of the interior of the vehicle or the interior of the aircraft. Exquisite painting is required. Therefore, it is not easy to paint separately.

また、上記参考図に示されるように、基板（２）や保護カバー（３）を取り付けるためにケーシングの長手方向に沿って延びる溝をケーシングに形成した場合、基板（２）等を側方から差し込んで組み付けることになる。そのため、ＬＥＤ灯具を客室の天井に取り付けた状態で基板（２）等をメンテナンスするときには、保護カバー（３）を側方に引き抜くため、ＬＥＤ灯具の側方には、基板（２）等の長さ相当の作業空間が必要になる。このような作業空間を確保できない場合には、一旦、天井や壁の取付面からＬＥＤ灯具を取り外さなければならない。よって、作業効率の低下を招く。 In addition, as shown in the above reference diagram, when a groove extending along the longitudinal direction of the casing is formed in the casing in order to attach the substrate (2) or the protective cover (3), the substrate (2) or the like is viewed from the side. It will be inserted and assembled. Therefore, when maintaining the board (2) or the like with the LED lamp mounted on the ceiling of the passenger room, the protective cover (3) is pulled out to the side. A considerable working space is required. If such a working space cannot be secured, the LED lamp must be removed from the ceiling or wall mounting surface. Therefore, work efficiency is reduced.

本発明は、上述した課題を解決するためになされたもので、塗装時の塗り分け作業を容易にし得るＬＥＤ灯具を提供することを目的とする。また、組付性やメンテナンス性を向上し得るＬＥＤ灯具を提供することを目的とする。 The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an LED lamp capable of facilitating painting work during painting. Moreover, it aims at providing the LED lamp which can improve an assembly | attachment property and maintainability.

That is, the mounting groove 25b is formed on the opposite side of the positioning portion 24b in the “>”-shaped portion of the housing portion 22 in which the positioning portion 24b is formed in the vicinity. Further, a female screw portion 28 for screwing a side cover 80 to be described later is also formed on the end portion of the accommodating portion 22 in the direction in which the radiating fin 23 hangs down from the mounting groove 25b.

このように形成される開口部２０ａや開口部２０ｂの短手方向外側には、サイドカバー８０の円弧状の輪郭に沿って傾斜するスロープ部２６が形成されており、このスロープ部２６の縁端には、当該ＬＥＤ灯具１０を天井や壁に取り付けた場合に取付面１００に当接する当接部２７が形成されている。この当接部２７は、図３に示すように、その断面形状がスロープ部２６の縁端から取付面１００に沿って短手方向内側に折り返すように形成されており、本実施形態では、取付面１００との間に緩衝材を介して取付面１００に当接している。なお、開口部２０ａ，２０ｂとスロープ部２６との境界部分には、サイドカバー８０をねじ締結するための雌ねじ部２８が形成されている。 A slope portion 26 that is inclined along the arc-shaped contour of the side cover 80 is formed on the outer side in the short direction of the opening portion 20a and the opening portion 20b thus formed.

As shown in FIG. 3, the abutment portion 27 is formed so that its cross-sectional shape is folded back inward in the lateral direction along the attachment surface 100 from the edge of the slope portion 26. The mounting surface 100 is in contact with the surface 100 through a cushioning material. A female screw portion 28 for screwing the side cover 80 is formed at a boundary portion between the openings 20a and 20b and the slope portion 26.

本実施形態では、図３に示すように、開口部２０ａ，２０ｂが形成される本体ケース２０の表側は、中央部２１を中心に短手方向において左右対称の形状に形成されている。そのため、次に説明する反射板３０，４０も、開口部２０ａ，２０ｂの形状に合わせて左右対称に位置している。 In the present embodiment, as shown in FIG. 3, the front side of the main body case 20 in which the openings 20 a and 20 b are formed is formed in a symmetrical shape in the lateral direction with the central portion 21 as the center. For this reason, the reflectors 30 and 40 described below are also positioned symmetrically in accordance with the shapes of the openings 20a and 20b.

反射板３０，４０は、本体ケース２０とほぼ同じ長さを有し短手方向に湾曲する薄板状に形成されている。これらの反射板３０，４０も、本体ケース２０と同様に、例えばアルミニウムからなり、図３に示す断面形状（または端部形状）が押出または切削加工により一端側から他端側まで連続して形成されている。なお、反射板３０および反射板４０は、図１〜図３に示すように、左右対称形状である。そのため、ここでは反射板３０の形状を代表して説明し、反射板４０については該当する符号を括弧書きで示すことにする。 The reflecting plates 30 and 40 are formed in a thin plate shape that has substantially the same length as the main body case 20 and curves in the lateral direction. These reflectors 30 and 40 are also made of, for example, aluminum like the main body case 20, and the cross-sectional shape (or end shape) shown in FIG. 3 is continuously formed from one end side to the other end side by extrusion or cutting. Has been. In addition, as shown in FIGS. 1-3, the reflecting plate 30 and the reflecting plate 40 are left-right symmetric shapes. Therefore, here, the shape of the reflecting plate 30 will be described as a representative, and the corresponding reference numerals for the reflecting plate 40 will be shown in parentheses.

反射板３０（４０）は、本体ケース２０の開口部２０ａ（２０ｂ）に取り付けられて、収容部２２に収容された発光部５０から出射される照明光を反射して客室内等を照らす機能を有する。そのため、反射板３０（４０）は、図３に示すように、その断面形状（または端部形状）が客室方向に向けて凹形状をなすように湾曲する湾曲部を有する。なお、以下、反射板３０（４０）の凹形状側を「反射板３０（４０）の表側」、またその裏側を「反射板３０（４０）の裏側」と称する。 The reflection plate 30 (40) is attached to the opening 20a (20b) of the main body case 20, and reflects the illumination light emitted from the light emitting unit 50 accommodated in the accommodation unit 22 to illuminate the interior of the cabin or the like. Have. Therefore, as shown in FIG. 3, the reflecting plate 30 (40) has a curved portion that curves so that its cross-sectional shape (or end shape) forms a concave shape toward the cabin direction. Hereinafter, the concave side of the reflecting plate 30 (40) is referred to as “the front side of the reflecting plate 30 (40)”, and the back side thereof is referred to as “the back side of the reflecting plate 30 (40)”.

反射板３０（４０）の裏側には、前述した本体ケース２０の位置決め部２４ａ（２４ｂ）に係合可能な位置決め部３１（４１）が形成されている。この位置決め部３１（４１）は、湾曲部の短手方向内側端部付近に位置しており、その断面形状は、短手方向内側に向かってやや傾いた凸形状に設定されている。これにより、位置決め部２４ａ（２４ｂ）に適した係合を可能にしている。 On the back side of the reflecting plate 30 (40), a positioning portion 31 (41) that can be engaged with the positioning portion 24a (24b) of the main body case 20 is formed. The positioning portion 31 (41) is located near the inner end in the short direction of the bending portion, and its cross-sectional shape is set to a convex shape that is slightly inclined toward the inner side in the short direction. Thereby, the engagement suitable for positioning part 24a (24b) is enabled.

位置決め部３１（４１）の近傍、つまり湾曲部の短手方向内側端部には、その断面形状（または端部形状）が「レ字」形状に反射板３０（４０）の裏側に向けて折れ曲がる内当接部３５（４５）が形成されている。この内当接部３５（４５）は、反射板３０（４０）の短手方向内側端部でもあることから、反射板３０（４０）が開口部２０ａ（２０ｂ）に取り付けられた場合に透光性カバー６０を収容部２２側に押圧する機能を有する。 In the vicinity of the positioning portion 31 (41), that is, the inner end portion in the short direction of the bending portion, the cross-sectional shape (or end shape) bends toward the back side of the reflector 30 (40) in a “letter shape”. An inner contact portion 35 (45) is formed. Since the inner contact portion 35 (45) is also the inner end portion in the short direction of the reflecting plate 30 (40), the translucent light is transmitted when the reflecting plate 30 (40) is attached to the opening 20a (20b). It has a function which presses the property cover 60 to the accommodating part 22 side.

これに対して、反射板３０（４０）の短手方向外側端部には、スロープ部３６（４６）と外当接部３７（４７）が形成されている。即ち、反射板３０（４０）の裏側で内側方向に折り返される外当接部３７（４７）と、断面形状（または端部形状）において、外当接部３７（４７）とともに「フ字」形状を構成するように反射板３０（４０）の湾曲部に繋がるスロープ部３６（４６）と、が湾曲部の短手方向外側端部に形成されている。この外当接部３７（４７）は、サイドカバー８０に形成される係止凸部等により、開口部２０ａ（２０ｂ）の外側平坦部に当接した状態を維持するように、短手方向および高さ方向の移動が規制される。 On the other hand, a slope portion 36 (46) and an outer abutting portion 37 (47) are formed at the outer end in the short direction of the reflector 30 (40). That is, the outer abutting portion 37 (47) folded back inward on the back side of the reflector 30 (40), and the cross-sectional shape (or end shape) together with the outer abutting portion 37 (47) and the “F” shape. And a slope portion 36 (46) connected to the curved portion of the reflecting plate 30 (40) is formed at the outer lateral end of the curved portion. The outer abutting portion 37 (47) is arranged in the short direction and so as to maintain a state where it abuts on the outer flat portion of the opening 20a (20b) by a locking projection formed on the side cover 80 or the like. Movement in the height direction is restricted.

図３および図４に示すように、発光部５０は、短冊形状をなすＬＥＤ基板５１と、このＬＥＤ基板５１の長手方向に沿って列状に実装される複数のＬＥＤ５３とから構成されている。発光部５０には、渡り配線９２から給電される直流１００Ｖを降圧するＬＥＤ電源装置９０を介して駆動電源が供給されている。本実施形態では、複数のＬＥＤ基板５１が電気的に並列に接続されており、駆動電源がそれぞれに供給されている。なお、図２においては配線の図示を省略している。 As shown in FIG. 3 and FIG. 4, the light emitting unit 50 includes a strip-shaped LED substrate 51 and a plurality of LEDs 53 mounted in a row along the longitudinal direction of the LED substrate 51. Driving power is supplied to the light emitting unit 50 via an LED power supply device 90 that steps down the DC 100V fed from the crossover wiring 92. In the present embodiment, a plurality of LED substrates 51 are electrically connected in parallel, and drive power is supplied to each. In addition, illustration of wiring is abbreviate | omitted in FIG.

この発光部５０は、開口部２０ａ側の収容部２２および開口部２０ｂ側の収容部２２のいずれにも収容されており、Ｌ字金具７０を介して本体ケース２０に固定されている。即ち、開口部２０ａ側の収容部２２に収容される発光部５０は、反射板３０の短手方向内側端部から斜めに湾曲部の短手方向ほぼ中央に入射するように、また開口部２０ｂ側の収容部２２に収容される発光部５０は、反射板４０の短手方向内側端部から斜めに湾曲部の短手方向ほぼ中央に入射するように、それぞれ本体ケース２０に固定されている。 The light emitting unit 50 is accommodated in both the accommodating portion 22 on the opening 20 a side and the accommodating portion 22 on the opening 20 b side, and is fixed to the main body case 20 via an L-shaped metal fitting 70. That is, the light emitting part 50 accommodated in the accommodating part 22 on the opening part 20a side is incident from the inner end part in the short direction of the reflecting plate 30 obliquely to substantially the center in the short direction of the curved part, and the opening part 20b. The light emitting parts 50 accommodated in the side accommodating part 22 are respectively fixed to the main body case 20 so as to be incident obliquely from the inner end part in the short direction of the reflecting plate 40 to substantially the center in the short direction of the curved part. .

このように発光部５０を本体ケース２０に固定するＬ字金具７０は、本体ケース２０とほぼ同等の長さを有する長尺状のアルミニウム板で、前述した収容部２２の「＜」字形状部および「＞」字形状部に適合可能なＬ字形状の端部形状を有しその端部形状が一端側から他端側まで連続して形成されているものである。 The L-shaped metal fitting 70 for fixing the light emitting unit 50 to the main body case 20 in this way is a long aluminum plate having substantially the same length as the main body case 20, and the “<”-shaped portion of the housing portion 22 described above. And an L-shaped end shape that can be adapted to the “>”-shaped portion, and the end shape is formed continuously from one end side to the other end side.

図３に示すように、Ｌ字形状の外向面側を収容部２２に接するようにＬ字金具７０を本体ケース２０に取り付けた場合、Ｌ字形状の内向面側のうち、反射板３０（４０）に向く面側に発光部５０（ＬＥＤ基板５１）を取り付ける。発光部５０（ＬＥＤ基板５１）の取り付けには、例えば両面テープを使用してＬ字金具７０に貼着する。また、Ｌ字形状の内向面側のうち、発光部５０（ＬＥＤ基板５１）を貼着しない側にねじ穴を形成して収容部２２にＬ字金具７０をねじ止め固定する。 As shown in FIG. 3, when the L-shaped metal fitting 70 is attached to the main body case 20 so that the L-shaped outward surface side is in contact with the housing portion 22, the reflector 30 (40 The light emitting part 50 (LED substrate 51) is attached to the surface side facing (). The light emitting unit 50 (LED substrate 51) is attached to the L-shaped metal fitting 70 using, for example, a double-sided tape. Further, a screw hole is formed on the side of the L-shaped inward surface on which the light emitting unit 50 (LED substrate 51) is not attached, and the L-shaped metal fitting 70 is fixed to the housing unit 22 with screws.

これにより、発光部５０から発せられたＬＥＤ５３の光は、反射板３０，４０の湾曲部に向けて出射されるため、反射板３０，４０により反射された光が客室内に向けた照明光として出射される。またＬ字金具７０の内向面側のうち、発光部５０が貼着されていない面（光沢を有する面）にも、ＬＥＤ５３の光が反射して客室内に向けて出射される。 Thereby, since the light of LED53 emitted from the light emission part 50 is radiate | emitted toward the curved part of the reflecting plates 30 and 40, the light reflected by the reflecting plates 30 and 40 is used as illumination light toward the cabin. Emitted. Moreover, the light of LED53 reflects and is radiate | emitted toward a passenger room also on the surface (surface which has glossiness) to which the light emission part 50 is not stuck among the inward surface sides of the L-shaped metal fitting 70.

透光性カバー６０は、本体ケース２０とほぼ同じ長さの短冊状に形成されたガラス板６１に同じく短冊状に形成された拡散シート６２を貼付したもので、発光部５０を収容した収容部２２の短手方向開口部を覆うものである。この透光性カバー６０は、開口部２０ａの収容部２２および開口部２０ｂの収容部２２のいずれにも取り付けられており、収容部２２に形成される取付溝２５ａ（２５ｂ）と、反射板３０（４０）の内当接部３５（４５）とにより、収容部２２に固定される。 The translucent cover 60 is obtained by attaching a diffusion sheet 62 that is also formed in a strip shape to a glass plate 61 that is formed in a strip shape that is substantially the same length as the main body case 20. The 22 opening portions in the short direction are covered. The translucent cover 60 is attached to both the accommodating portion 22 of the opening 20a and the accommodating portion 22 of the opening 20b, the mounting groove 25a (25b) formed in the accommodating portion 22, and the reflecting plate 30. The inner contact portion 35 (45) of (40) is fixed to the accommodating portion 22.

即ち、透光性カバー６０の長手方向（図１〜図４に示すＹ軸方向）に対する短手方向（図１〜図４に示すＺ軸方向）一端側が収容部２２の取付溝２５ａ（２５ｂ）に係止され、また同短手方向の他端側が反射板３０（４０）の内当接部３５（４５）により収容部２２（本体ケース２０）に押圧されて、透光性カバー６０が収容部２２（本体ケース２０）に固定される。これにより、透光性カバー６０の短手方向両端部が、取付溝２５ａ（２５ｂ）のような溝にはめ込まれて取り付けられる構造の場合（特許文献１に開示される「使用状態を示すＡ−Ａ線参考拡大断面図」）に比べ、透光性カバー６０の短手方向一端側にしか取付溝２５ａ（２５ｂ）が形成されていない。そのため、透光性カバー６０を本体ケース２０の側方からスライドさせることなく、収容部２２の短手方向開口部から透光性カバー６０を組み付けることが可能になる。 That is, one end side of the translucent cover 60 with respect to the longitudinal direction (Y-axis direction shown in FIGS. 1 to 4) (Z-axis direction shown in FIGS. 1 to 4) is the mounting groove 25a (25b) of the housing portion 22. The other end side in the short direction is pressed against the housing portion 22 (main body case 20) by the inner contact portion 35 (45) of the reflector 30 (40), so that the translucent cover 60 is housed. It is fixed to the part 22 (main body case 20). Thereby, in the case of a structure in which both ends in the short direction of the translucent cover 60 are fitted into a groove such as the mounting groove 25a (25b) (disclosed in “Patent Document A- Compared with the A-line reference enlarged sectional view "), the mounting groove 25a (25b) is formed only on one end side of the translucent cover 60 in the short direction. Therefore, the translucent cover 60 can be assembled from the opening in the short direction of the housing portion 22 without sliding the translucent cover 60 from the side of the main body case 20.

したがって、メンテナンス時において、ＬＥＤ灯具１０の側方に透光性カバー６０の長さ相当の作業空間を確保する必要がなく、またＬＥＤ灯具１０を天井や壁の取付面から取り外す必要もない。また、組付時においても、透光性カバー６０を本体ケース２０の側方からスライドさせて本体ケース２０の収容部２２に差し込む必要がないため、ＬＥＤ灯具１０の側方に、透光性カバー６０の長さ相当の作業空間を確保する必要がない。 Therefore, at the time of maintenance, it is not necessary to secure a work space corresponding to the length of the translucent cover 60 on the side of the LED lamp 10, and it is not necessary to remove the LED lamp 10 from the ceiling or wall mounting surface. In addition, since the translucent cover 60 does not need to be slid from the side of the main body case 20 and inserted into the housing portion 22 of the main body case 20 even during assembly, the translucent cover is formed on the side of the LED lamp 10. It is not necessary to secure a work space equivalent to 60 lengths.

なお、本実施形態では、拡散シート６２がガラス板６１の収容部２２側に貼付されており、この拡散シート６２と収容部２２の間に緩衝材６５を介在させている。これにより、透光性カバー６０や反射板３０の（４０）等を組み付けた状態において、拡散シート６２に内当接部３５（４５）が直接触れることがないため、拡散シート６２が内当接部３５（４５）によって傷が付いたり、破れたりすることがない。また、透光性カバー６０と収容部２２との間に緩衝材６５が介在することによって、反射板３０の（４０）の内当接部３５（４５）による押圧力や寸法誤差を吸収することが可能になり、透光性カバー６０のガタツキや透光性カバー６０の破損を防止することができる。 In the present embodiment, the diffusion sheet 62 is affixed to the accommodation portion 22 side of the glass plate 61, and a buffer material 65 is interposed between the diffusion sheet 62 and the accommodation portion 22. As a result, the inner contact portion 35 (45) does not directly touch the diffusion sheet 62 in the state where the translucent cover 60 or the reflector plate (40) is assembled. The part 35 (45) is not scratched or torn. Further, the buffer material 65 is interposed between the translucent cover 60 and the accommodating portion 22 to absorb the pressing force and dimensional error due to the inner contact portion 35 (45) of the (40) of the reflecting plate 30. It is possible to prevent backlash of the translucent cover 60 and breakage of the translucent cover 60.

The overall shape of the reflecting plate 40 can be grasped by conceptualizing the left and right sides and the top and bottom in reverse from the six views and the perspective view of the reflecting plate 30 shown in FIG.

ところで、本実施形態に係るＬＥＤ灯具１０では、上述したように、本体ケース２０とは別体に、本体ケース２０に開口する開口部２０ａ，２０ｂに２枚の反射板３０，４０が設けられる。このため、例えば、反射板３０，４０とは、別の塗装色で本体ケース２０を塗装する場合、反射板３０，４０と本体ケース２０を別々に塗装することで、容易に両者を別色で塗装することができる。これにより、マスキングテープ等を用いることなく、反射板３０，４０と本体ケース２０を塗り分けることが可能になる。 Meanwhile, in the LED lamp 10 according to the present embodiment, as described above, the two reflectors 30 and 40 are provided in the openings 20a and 20b that open to the main body case 20, separately from the main body case 20. For this reason, for example, when the main body case 20 is painted with a different coating color from the reflecting plates 30 and 40, the reflecting plates 30 and 40 and the main body case 20 can be easily painted with different colors. Can be painted. This makes it possible to coat the reflectors 30 and 40 and the main body case 20 separately without using a masking tape or the like.

また、例えば、図８に示すように、本体ケース２０自体に別の塗装色で塗り分ける部分α，βが指定されている場合（例えば、太線部分αの範囲は灰色、太線部分βの範囲は白色）でも、塗り分けの境界を、反射板３０，４０、発光部５０や透光性カバー６０等で本体ケース２０の表面が隠れる範囲に設定することで、塗り分けの境界を反射板３０，４０等で隠すことが可能になる。これにより、このような場合であっても、マスキングテープ等を用いることなく、塗り分け作業を行うことができる。したがって、塗装時の塗り分け作業を容易にすることができる。 For example, as shown in FIG. 8, when the parts α and β to be painted with different paint colors are designated on the main body case 20 itself (for example, the range of the thick line part α is gray, the range of the thick line part β is Even in the case of white), by setting the boundary between the different colors within a range in which the surface of the main body case 20 is hidden by the reflectors 30 and 40, the light emitting unit 50, the translucent cover 60, and the like, It becomes possible to hide at 40 mag. Thereby, even in such a case, it is possible to perform the painting operation without using a masking tape or the like. Therefore, it is possible to facilitate the painting operation during painting.

以上説明したように、本実施形態に係るＬＥＤ灯具１０では、取付面１００の反対側に向けて開口する開口部２０ａ，２０ｂがＬＥＤ灯具１０の長手方向に沿って２列に並んで連続して形成される本体ケース２０と、開口部２０ａ，２０ｂの長手方向長さとほぼ同等の長さを有するとともに湾曲形状をなす端部形状が一端側から他端側まで連続して形成され、取付面１００の反対側に向けて開口するように２列の開口部２０ａ，２０ｂのそれぞれに設けられる２枚の反射板３０，４０と、複数のＬＥＤ５３が列状に配置されるＬＥＤ列を複数備え、反射板３０，４０の短手方向側方から斜めに入射するように２枚の反射板３０，４０のうち、一方の反射板３０に一群のＬＥＤ列の発光側を向け、他方の反射板４０に他群のＬＥＤ列の発光側を向けて２列の開口部２０ａ，２０ｂの間に設けられ、発せられた光がこれらの反射板３０，４０に反射して照明光として外部に出射される発光部５０と、を備える。 As described above, in the LED lamp 10 according to this embodiment, the openings 20 a and 20 b that open toward the opposite side of the mounting surface 100 are continuously arranged in two rows along the longitudinal direction of the LED lamp 10. A main body case 20 to be formed and an end shape that has a length substantially equal to the length in the longitudinal direction of the openings 20a and 20b and forms a curved shape are continuously formed from one end side to the other end side. Two reflectors 30 and 40 provided in each of the two rows of openings 20a and 20b so as to open toward the opposite side, and a plurality of LED rows in which a plurality of LEDs 53 are arranged in a row. Of the two reflectors 30, 40, the light emission side of the group of LED rows is directed to one reflector 30 and the other reflector 40 is directed to the other reflector 40 so as to enter obliquely from the lateral direction side of the plates 30, 40. The light emission side of another group of LED rows Only provided between the two rows of openings 20a, 20b, includes a light emitting portion 50 the emitted light is emitted to the outside as illumination light is reflected on these reflector 30 and 40, the.

これにより、マスキングテープ等を用いることなく、塗り分けを可能にすることから、塗装時の塗り分け作業を容易にすることができる。また、組付時やメンテナンス時において、ＬＥＤ灯具１０を、一旦、天井や壁の取付面から取り外す必要がなくなることから、組付性やメンテナンス性を向上することができる。 Thereby, it is possible to perform painting without using a masking tape or the like, so that the painting work at the time of painting can be facilitated. In addition, since it is not necessary to remove the LED lamp 10 from the ceiling or wall mounting surface once during assembly or maintenance, assembly and maintenance can be improved.

また、本実施形態に係るＬＥＤ灯具１０では、発光部５０と反射板３０，４０との間には、発光部５０の長手方向長さ（または本体ケース２０の長手方向長さ）とほぼ同等の長さを有する短冊形状の透光性カバー６０が介在しており、透光性カバー６０の短手方向の一端側が本体ケース２０の長手方向に沿って形成される取付溝２５に係止され、透光性カバー６０の短手方向の他端側が反射板３０，４０の内当接部３５，４５により収容部２２に押圧されて、本体ケース２０に固定される。 Further, in the LED lamp 10 according to the present embodiment, the length in the longitudinal direction of the light emitting unit 50 (or the length in the longitudinal direction of the main body case 20) is substantially equal between the light emitting unit 50 and the reflectors 30 and 40. A strip-shaped translucent cover 60 having a length is interposed, and one end side of the translucent cover 60 in the short direction is locked to a mounting groove 25 formed along the longitudinal direction of the main body case 20. The other end side of the translucent cover 60 in the short direction is pressed against the housing portion 22 by the inner contact portions 35 and 45 of the reflecting plates 30 and 40 and fixed to the main body case 20.

これにより、収容部２２の短手方向開口部から透光性カバー６０を組み付けることができるので、組付時においては、発光部５０の長手方向長さとほぼ同等の長さを有する短冊形状の透光性カバー６０を本体ケース２０の側方からスライドさせて本体ケース２０に差し込んだり、またメンテナンス時においては、このような長尺の透光性カバー６０をスライドさせて本体ケース２０の側方から引き抜いたり、する必要がない。そのため、当該ＬＥＤ灯具の側方に、透光性カバーの長さ相当の作業空間を確保する必要がなくなることから、組付時に作業空間を作ったり、メンテナンス時に、一旦、ＬＥＤ灯具を、天井や壁の取付面から取り外したりする必要がない。また、透光性カバー６０を本体ケース２０の側方からスライドさせる構成を採る場合にこのようなスライドをスムースにするため、取付溝の溝幅を広くしたり、透光性カバー６０を薄くしたりする必要もなくなることから、透光性カバーの固定に要する溝幅以上の溝部を形成しなくてもよい。これにより、透光性カバーをスムースにスライドさせるため、透光性カバーの固定に要する溝幅以上に溝部を形成していた場合に比べて、走行時や航行時の振動によるビビリ音を抑制することが可能になる。 As a result, the translucent cover 60 can be assembled from the opening in the short direction of the accommodating portion 22, so that the strip-shaped transparent portion having a length substantially equal to the length in the longitudinal direction of the light emitting portion 50 at the time of assembly. The optical cover 60 is slid from the side of the main body case 20 and inserted into the main body case 20, and at the time of maintenance, such a long translucent cover 60 is slid from the side of the main body case 20. There is no need to pull it out. Therefore, there is no need to secure a working space equivalent to the length of the translucent cover on the side of the LED lamp, so that a working space is created during assembly or once the LED lamp is mounted on the ceiling or during maintenance. There is no need to remove it from the wall mounting surface. In addition, when adopting a configuration in which the translucent cover 60 is slid from the side of the main body case 20, in order to make such a slide smooth, the groove width of the mounting groove is widened or the translucent cover 60 is thinned. Therefore, it is not necessary to form a groove portion larger than the groove width required for fixing the translucent cover. As a result, since the light-transmitting cover is smoothly slid, chatter noise caused by vibration during traveling and navigation is suppressed as compared to the case where the groove portion is formed beyond the groove width required for fixing the light-transmitting cover. It becomes possible.

さらに、本実施形態に係るＬＥＤ灯具１０では、発光部５０は、複数のＬＥＤ５３が列状に実装される長尺状の一対のＬＥＤ基板５１と、一対のＬＥＤ基板５１のそれぞれに対して設けられ、ＬＥＤ基板５１とほぼ同等の長さを有するとともにＬ字形状をなす端部形状が一端側から他端側まで連続し、かつＬ字形状の内向面が光沢を有する一対のＬ字金具７０と、を備える。そして、Ｌ字金具７０の外向面側が収容部２２（本体ケース２０）に接するようにＬ字金具７０を収容部２２に取り付けた場合、Ｌ字金具７０の内向面側のうち反射板３０，４０に向く面側にＬＥＤ基板５１を取り付ける。 Furthermore, in the LED lamp 10 according to the present embodiment, the light emitting unit 50 is provided for each of the pair of long LED substrates 51 on which the plurality of LEDs 53 are mounted in a row and the pair of LED substrates 51. A pair of L-shaped metal fittings 70 having substantially the same length as the LED substrate 51 and having an L-shaped end portion continuous from one end side to the other end side, and having an L-shaped inward surface having a gloss . When the L-shaped metal fitting 70 is attached to the housing portion 22 so that the outward surface side of the L-shaped metal fitting 70 is in contact with the housing portion 22 (main body case 20), the reflectors 30, 40 of the inward surface side of the L-shaped metal fitting 70. The LED board 51 is attached to the side facing the surface.

これにより、ＬＥＤ基板５１は、Ｌ字形状のＬ字金具７０を介して収容部２２の短手方向開口部から収容部２２（本体ケース２０）に取り付けられるため、組付時においては、長尺状の一対のＬＥＤ基板５１を本体ケース２０の側方からスライドさせて本体ケース２０に差し込んだり、またメンテナンス時においては、このような一対のＬＥＤ基板５１をスライドさせて本体ケース２０の側方から引き抜いたり、する必要がなくなる。そのため、ＬＥＤ灯具１０の側方に、ＬＥＤ基板５１の長さ相当の作業空間を確保する必要がないことから、組付時に作業空間を作ったり、メンテナンス時に、一旦、ＬＥＤ灯具１０を、天井や壁の取付面から取り外したりする必要がない。また、収容部２２（本体ケース２０）にねじ締結されるＬ字金具７０を介してＬＥＤ基板５１を収容部２２に取り付ける構成を採ることから、両面テープや接着剤によりＬＥＤ基板５１を収容部２２に貼着する構成を採る場合に比べて、メンテナンス時におけるＬＥＤ基板５１の取り外しが容易になる。 Thereby, since the LED board 51 is attached to the accommodating part 22 (main body case 20) from the short direction opening part of the accommodating part 22 via the L-shaped L-shaped metal fitting 70, it is long at the time of an assembly | attachment. The pair of LED substrates 51 are slid from the side of the main body case 20 and inserted into the main body case 20, or during maintenance, the pair of LED substrates 51 are slid from the side of the main body case 20. There is no need to pull it out. Therefore, it is not necessary to secure a working space corresponding to the length of the LED substrate 51 on the side of the LED lamp 10, so that a working space is created during assembly or the LED lamp 10 is temporarily attached to the ceiling or There is no need to remove it from the wall mounting surface. Further, since the LED substrate 51 is attached to the housing portion 22 via an L-shaped metal fitting 70 screwed to the housing portion 22 (main body case 20), the LED substrate 51 is placed on the housing portion 22 with a double-sided tape or an adhesive. The LED substrate 51 can be easily removed at the time of maintenance as compared with the case of adopting a configuration in which the LED substrate 51 is adhered to the surface.
