Description

本発明は、複数個の発光素子を備えて他所に取り付けられる発光装置およびこの発光装置を用いた照明器具に関するものである。 The present invention relates to a light emitting device that includes a plurality of light emitting elements and is attached to another place, and a lighting fixture using the light emitting device.

従来より、複数個の発光素子であるＬＥＤを備えた発光装置が知られている（例えば、特許文献１参照）。
図１２に示すように、特許文献１の発光装置である照明モジュール１００は、基板モジュール１０１と反射板１０２とカバー１０３とを有する。
基板モジュール１０１は、薄い板状の基板１０４を有しており、基板１０４の表面に複数の光源であるＬＥＤ１０５と、接続部であるコネクタ１０６が実装されている。
複数のＬＥＤ１０５は、基板１０４の表面の幅方向の端部寄りに配置されており、コネクタ１０６は、ＬＥＤ１０５とは反対側の端部寄りに配置されている。また、基板１０４の幅方向におけるコネクタ１０６寄りには取付孔１０７を有する。 2. Description of the Related Art Conventionally, a light emitting device including a plurality of LEDs that are light emitting elements is known (see, for example, Patent Document 1).
As illustrated in FIG. 12, an illumination module 100 that is a light emitting device of Patent Document 1 includes a substrate module 101, a reflector 102, and a cover 103.
The substrate module 101 has a thin plate-like substrate 104, and a plurality of LEDs 105 as light sources and a connector 106 as a connection portion are mounted on the surface of the substrate 104.
The plurality of LEDs 105 are disposed near the end in the width direction of the surface of the substrate 104, and the connector 106 is disposed near the end opposite to the LED 105. A mounting hole 107 is provided near the connector 106 in the width direction of the substrate 104.

これにより、長手方向端部付近まで、ＬＥＤ１０５の取付ピッチを等間隔で密にすることができる。
また、コネクタ１０６の電線が複数のＬＥＤ１０５の発光を妨害することがなく、配線がしやすい。
なお、基板１０４の表面には、反射板１０２およびカバー１０３が取り付けられる。 Thereby, the mounting pitch of the LED 105 can be made dense at regular intervals up to the vicinity of the end in the longitudinal direction.
Moreover, the electric wire of the connector 106 does not disturb the light emission of the plurality of LEDs 105, and wiring is easy.
A reflective plate 102 and a cover 103 are attached to the surface of the substrate 104.

特開２０１０−１９９０１０号公報（第１図）JP 2010-199010 A (FIG. 1)

このような、前述した特許文献１に記載の発光装置（照明モジュール１００）においては、コネクタ１０６がＬＥＤ１０５の配列方向からずれているので、基板１０４等の幅が大きくなるという問題があった。
この問題に対しては、ＬＥＤ配列軸上の両端部中央部にコネクタを設け、基板幅を細くすればよい。
しかしながら、カバーを、基板や基板を支持する支持体にねじ止めで取り付ける際には、一般に、長手方向両端部でねじ止めするのが望ましい。このため、両端部においてねじ止めすると、ＬＥＤコネクタから導出している電線をねじが巻き込み、電線を傷つけたり、電線があるためにねじ止めの作業性が阻害されたりするという問題がある。 In such a light emitting device (illumination module 100) described in Patent Document 1 described above, since the connector 106 is displaced from the arrangement direction of the LEDs 105, there is a problem that the width of the substrate 104 and the like is increased.
To solve this problem, a connector may be provided at the center of both ends on the LED array axis to reduce the substrate width.
However, when the cover is attached to the substrate or the support that supports the substrate by screwing, it is generally desirable to screw the cover at both ends in the longitudinal direction. For this reason, when screwing in both ends, there exists a problem that a screw entrains the electric wire led out from the LED connector, damages the electric wire, or hinders the workability of screwing due to the electric wire.

本発明は、このような問題を解決するためになされたもので、基板の幅を広げることなく、カバーをねじで取り付ける際に、ねじが電線を巻き込んで電線を傷つけたり、組立の作業性が阻害されたりすることを防止することのできる発光装置および照明器具を提供することを目的とする。 The present invention has been made to solve such a problem. When the cover is attached with a screw without increasing the width of the substrate, the screw entrains the electric wire and damages the electric wire. It is an object of the present invention to provide a light emitting device and a lighting fixture that can be prevented from being hindered.

Therefore, unless otherwise indicated, upper (upper, upper, etc.) means the ceiling surface side, and lower (lower, lower, etc.) means the floor surface side.

図１（Ａ）および（Ｂ）に示すように、本発明に係る第１実施形態の照明器具１０は、被取付部である天井面１１等に取り付けられて主に下方を照明するのに適する。
図２にも示すように、照明器具１０は、天井面１１に取り付けられている引っ掛けシーリング１２に取り付けるための取付部材２１を中央に有する、例えば円板状の器具本体２０を有する。
また、器具本体２０の中央部における取付部材２１の近傍には、常夜灯２３が設けられている。
なお、器具本体２０の外周には、例えば円環状の枠体２２が設けられており、枠体２２には詳細を後述する半導体発光素子として例えばＬＥＤを光源とする発光装置である補助光源７０が設けられている。 As shown to FIG. 1 (A) and (B), the lighting fixture 10 of 1st Embodiment which concerns on this invention is attached to the ceiling surface 11 grade | etc., Which is a to-be-attached part, and is suitable for mainly illuminating the downward direction. .
As shown also in FIG. 2, the lighting fixture 10 has, for example, a disk-like fixture main body 20 having an attachment member 21 for attachment to the hook ceiling 12 attached to the ceiling surface 11.
In addition, a nightlight 23 is provided in the vicinity of the attachment member 21 in the central portion of the instrument body 20.
For example, an annular frame 22 is provided on the outer periphery of the instrument body 20, and an auxiliary light source 70, which is a light-emitting device using, for example, an LED as a light source, is used as a semiconductor light-emitting element described in detail later. Is provided.

器具本体２０の上側（すなわち、天井面１１側）には、間接光源であるアッパーユニット３０、上枠３２および上カバー３１が設けられている。
また、器具本体２０の下側（すなわち、照明方向側）には、主光源であるロアーユニット４０、主光源用の光学部材であるレンズ４３が設けられている。 An upper unit 30 that is an indirect light source, an upper frame 32, and an upper cover 31 are provided on the upper side of the instrument body 20 (that is, on the ceiling surface 11 side).
Further, a lower unit 40 that is a main light source and a lens 43 that is an optical member for the main light source are provided below the instrument body 20 (that is, on the illumination direction side).

ロアーユニット４０は、器具本体２０の円形を複数個に分割した部分円弧状の基板４１を有しており、各基板４１には、複数のＬＥＤ４２が実装されている。各ロアーユニット４０は、下方に向けて光を照射する。
ロアーユニット４０の前方には、ロアーユニット４０が発した光を受けて光を拡散する透光性のパネル５０が設けられている。パネル５０は、枠体２２に取り付けられる。パネル５０は、下方に湾曲した曲面形状を呈している。 The lower unit 40 includes a partial arc-shaped substrate 41 obtained by dividing the circular shape of the instrument body 20 into a plurality of pieces, and a plurality of LEDs 42 are mounted on each substrate 41.

The fixture 35 is generally L-shaped, and the substrate 34 and the lens 36 are attached so as to be orthogonal to the upper surface of the fixture body 20 so that the irradiation direction of the LEDs 33 faces the outside of the lighting fixture 10.
Therefore, the light from the LED 33 is emitted outward in parallel with the upper surface of the instrument body 20.

図４（Ａ）および（Ｂ）に示すように、枠体２２は円環状をしており、内部にはパネル５０が嵌まる空間２２１を有する。枠体２２の表面（下面２２２）は、中心に向かって下方へ傾斜しており、所定間隔（ここでは、中心角１２０度）で、補助光源７０用の開口部２２３が設けられている。開口部２２３は、枠体２２の外形に対応して、湾曲して設けられている。
また、枠体２２の表面（下面２２２）には、センサ用開口２２４、動作表示ランプ用開口２２５および状態表示ランプ用開口２２６が設けられている。
なお、センサ２４１、動作表示ランプ２４２および状態表示ランプ２４３は、器具本体２０に取り付けられているブラケット２４に取り付けられている（図２参照）。 As shown in FIGS. 4A and 4B, the frame body 22 has an annular shape, and has a space 221 in which the panel 50 is fitted. The front surface (lower surface 222) of the frame body 22 is inclined downward toward the center, and an opening 223 for the auxiliary light source 70 is provided at a predetermined interval (here, a central angle of 120 degrees). The opening 223 is provided in a curved shape corresponding to the outer shape of the frame body 22.
In addition, a sensor opening 224, an operation display lamp opening 225, and a state display lamp opening 226 are provided on the front surface (lower surface 222) of the frame body 22.
The sensor 241, the operation display lamp 242 and the status display lamp 243 are attached to a bracket 24 attached to the instrument body 20 (see FIG. 2).

図５および図６に示すように、補助光源７０は、表面７２１にＬＥＤ７１を実装した円弧状の回路基板７２と、回路基板７２を取り付ける取付体７３と、ＬＥＤ７１の前方を覆うカバー８０を有する。
回路基板７２、取付体７３およびカバー８０は、枠体２２の外形（円形）に合わせて湾曲しており、ＬＥＤ７１は、回路基板７２上に円弧状に実装されている。
なお、回路基板７２は円弧状に限らず、長方形や正方形等、他の形状でもよい。また、ＬＥＤ７１の配置も円弧状に限らず、ＬＥＤ７１を結ぶ線がジグザグ状や、波形、山形等の線状となるよう配置されたものでもよい。 As shown in FIGS. 5 and 6, the auxiliary light source 70 includes an arc-shaped circuit board 72 having an LED 71 mounted on a surface 721, a mounting body 73 to which the circuit board 72 is attached, and a cover 80 that covers the front of the LED 71.
The circuit board 72, the attachment body 73, and the cover 80 are curved according to the outer shape (circular shape) of the frame body 22, and the LEDs 71 are mounted on the circuit board 72 in an arc shape.
The circuit board 72 is not limited to an arc shape, but may be other shapes such as a rectangle or a square. Further, the arrangement of the LEDs 71 is not limited to the arc shape, and the LEDs 71 may be arranged so that the line connecting the LEDs 71 has a zigzag shape, a waveform shape, a mountain shape, or the like.

回路基板７２のＬＥＤ７１が実装されている表面７２１において、各ＬＥＤ７１を結んだ円弧状の仮想線の延長線上の一端部中央部には、基板側コネクタ７５が取り付けられている。この基板側コネクタ７５は、ＬＥＤ７１に点灯電力を供給する電線７６に取り付けられている供給側コネクタ７６１に接続される。すなわち、電線７６の一端部は、カバー８０内において回路基板７２の端部中央部に接続されている。ここで、電線７６の一端部は回路基板７２に接続された部分、例えば一端部に供給側コネクタ７６１のことであり、他端部はこの供給側コネクタから延出した電線部分のことを示す。
本実施形態においては、電線接続部として基板側コネクタ７５は回路基板７２の一端部の端部中央部に設けられているが、両端部中央部に設けてもよい。 On the surface 721 of the circuit board 72 on which the LEDs 71 are mounted, a board-side connector 75 is attached to the center of one end on the extension line of the arcuate virtual line connecting the LEDs 71. The board-side connector 75 is connected to a supply-side connector 761 attached to an electric wire 76 that supplies lighting power to the LED 71. That is, one end of the electric wire 76 is connected to the center of the end of the circuit board 72 in the cover 80. Here, one end portion of the electric wire 76 is a portion connected to the circuit board 72, for example, one end portion is a supply side connector 761, and the other end portion is an electric wire portion extending from the supply side connector.
In the present embodiment, the board-side connector 75 is provided at the center of the end of one end of the circuit board 72 as the electric wire connecting part, but may be provided at the center of both ends.

なお、本実施形態において補助光源７０は、カバー８０の両端部をねじ止めによって取付本体７３１に固定しているが、一端部のみねじ止めしてもよい。その場合、電線接続部である基板側コネクタ７５を有していない側の回路基板の他端部を取付本体７３１の端部に係止する構造を有してもよい。すなわち、カバー８０の他端部と取付本体７３１の他端部とを係止した後、カバー８０の一端部と取付本体７３１の一端部とをねじ止めをして、固定すればよい。これによれば、ねじ止めは一カ所で済み、組立作業性が向上する。 In the present embodiment, the auxiliary light source 70 has both ends of the cover 80 fixed to the mounting body 731 by screwing, but only one end may be screwed. In that case, it may have a structure in which the other end portion of the circuit board on the side that does not have the board-side connector 75 that is the electric wire connecting portion is locked to the end portion of the attachment main body 731. That is, after the other end portion of the cover 80 and the other end portion of the mounting body 731 are locked, one end portion of the cover 80 and one end portion of the mounting body 731 may be fixed with screws. According to this, screwing is only required at one place, and the assembly workability is improved.

取付体７３は、平板状の取付体本体７３１の外側縁部に外壁７３２を設け、取付体本体７３１の内側縁部に内壁７３３を設けて、断面コ字形状を呈している。取付体７３は、金属製板部材を折曲げ加工して形成することができる。 The mounting body 73 has an outer wall 732 at the outer edge of the flat mounting body main body 731 and an inner wall 733 at the inner edge of the mounting body main body 731, and has a U-shaped cross section. The attachment body 73 can be formed by bending a metal plate member.

回路基板７２は外壁７３２と内壁７３３との間に配置される。
このため、ＬＥＤ７１から発せられた光のうち、外側に向かう光および内側に向かう光は、取付体７３の外壁７３２と内壁７３３により遮光されるので、外側に向かう光および内側に向かう光の漏れを防止できる。
なお、補助光源７０の長手方向（すなわち、周方向）の光の漏れは、枠体２２の開口部２２３の上面周方向端部に、遮光壁（図示省略）を設けて防止することができる。 The circuit board 72 is disposed between the outer wall 732 and the inner wall 733.
For this reason, out of the light emitted from the LED 71, the outward light and the inward light are shielded by the outer wall 732 and the inner wall 733 of the mounting body 73, so that leakage of the outward light and the inward light is prevented. Can be prevented.
Note that light leakage in the longitudinal direction (that is, circumferential direction) of the auxiliary light source 70 can be prevented by providing a light shielding wall (not shown) at the circumferential end portion of the upper surface of the opening 223 of the frame body 22.

取付体本体７３１の長手方向両端部における幅方向中央部には、取付体７３を例えば他所である器具本体２０に取り付けるための固定ねじ孔７３４が設けられている。
また、取付体本体７３１における固定ねじ孔７３４の長手方向内側には、カバー８０を取付体７３に取り付けるための取付ねじ孔７３５、７３６が設けられている。
取付ねじ孔７３５、７３６のうちの、基板側コネクタ７５が設けられている側の取付ねじ孔７３６は、外側に偏心して設けられている。
なお、この取付ねじ孔７３５、７３６は採用される構造に応じて適宜内側に設けてもよい。すなわち、カバー８０の長さ方向の中心軸を境に一方に取付ねじ孔７３５（７３６）、他方に電線が位置するように設けられていればよい。 Fixing screw holes 734 for attaching the attachment body 73 to, for example, the instrument body 20 at another location are provided at the center in the width direction at both longitudinal ends of the attachment body main body 731.
Further, mounting screw holes 735 and 736 for mounting the cover 80 to the mounting body 73 are provided on the inner side in the longitudinal direction of the fixing screw hole 734 in the mounting body main body 731.
Of the mounting screw holes 735 and 736, the mounting screw hole 736 on the side where the board-side connector 75 is provided is eccentrically provided outward.
The mounting screw holes 735 and 736 may be appropriately provided on the inner side depending on the structure employed. That is, the cover screw 80 735 (736) may be provided on one side with the central axis in the length direction of the cover 80 as a boundary, and the electric wire may be provided on the other side.

カバー８０は、湾曲した平板状のカバー本体８１と、カバー本体８１の内側において取付体７３側に延びる内側立壁８２１および外側において取付体７３側に延びる外側立壁８２２を有する。
また、カバー８０の長手方向両端には、各々取付部８３１、８３２が張り出して設けられており、取付ねじ８３５で取付体７３に取り付けるためのねじ孔８３３、８３４が設けられている。 The cover 80 includes a curved flat cover body 81, an inner standing wall 821 extending toward the mounting body 73 inside the cover body 81, and an outer standing wall 822 extending toward the mounting body 73 outside.
Further, at the both ends in the longitudinal direction of the cover 80, mounting portions 831 and 832 are provided so as to protrude, and screw holes 833 and 834 for mounting to the mounting body 73 with mounting screws 835 are provided.

取付部８３２およびねじ孔８３４は、外側に偏心して設けられており、取付部８３２の内側には、内側立壁８２１との間に、電線７６用の配線通路８４が設けられている。
従って、電線７６は、カバー８０の内側に設けられている内側立壁（壁部）８２１に沿って配線されるので、ＬＥＤ７１の実装線から径方向に沿って内側にずれて配線されることになる。すなわち、電線７６の他端部は、回路基板７２の端部中央部からずれて、カバー８０の内側立壁８２１に沿ってカバー８０外に導出されている。 The attachment portion 832 and the screw hole 834 are provided eccentrically on the outside, and a wiring passage 84 for the electric wire 76 is provided between the inside of the attachment portion 832 and the inner standing wall 821.
Therefore, since the electric wires 76 are wired along the inner standing wall (wall portion) 821 provided inside the cover 80, the electric wires 76 are arranged so as to be displaced inward along the radial direction from the mounting line of the LED 71. . That is, the other end of the electric wire 76 is shifted from the center of the end of the circuit board 72 and led out of the cover 80 along the inner standing wall 821 of the cover 80.

カバー８０の長手方向の一方の端部における内側である配線通路８４側の先端部には、取付体７３側（すなわち、上側）に突出する突起部８５を設けた。
従って、図７に示すように、補助光源７０を組み立てた際に、カバー８０の突起部８５が、取付体７３の端面７３７に当接するので、取付体７３に対するカバー８０の位置決めが容易になる。 A protrusion 85 that protrudes toward the attachment body 73 (that is, the upper side) is provided at the distal end on the wiring passage 84 side, which is the inner side at one end in the longitudinal direction of the cover 80.
Accordingly, as shown in FIG. 7, when the auxiliary light source 70 is assembled, the protrusion 85 of the cover 80 abuts on the end surface 737 of the attachment body 73, so that the cover 80 can be easily positioned with respect to the attachment body 73.

図５および図８（Ａ）、（Ｂ）に示すように、カバー８０の内側立壁８２１の内面上端部および外側立壁８２２の内面上端部には、回路基板７２が嵌合する溝部８６が、対向して設けられている。
回路基板７２は、溝部８６に嵌合してカバー８０に取り付けた状態では、取付体７３とカバー８０との取付面８１１に対して、回路基板７２の裏面７２２および取付体７３の下面（回路基板側面）７３８のうちの一方の面が他方の面に向かって突出している。
ここでは、回路基板７２の裏面７２２が取付体７３の下面７３８に向かって突出している。 As shown in FIGS. 5, 8 A, and 8 B, a groove portion 86 into which the circuit board 72 is fitted is opposed to the inner surface upper end portion of the inner standing wall 821 and the inner surface upper end portion of the outer standing wall 822 of the cover 80. Is provided.
When the circuit board 72 is fitted in the groove 86 and attached to the cover 80, the circuit board 72 has a back surface 722 of the circuit board 72 and a lower surface of the mounting body 73 (circuit board) with respect to the mounting surface 811 between the mounting body 73 and the cover 80. One of the side surfaces 738 protrudes toward the other surface.
Here, the back surface 722 of the circuit board 72 protrudes toward the lower surface 738 of the attachment body 73.

すなわち、図８（Ａ）に示すように、溝部８６の深さＤ１（例えば、０．８ｍｍ）は、回路基板７２の厚さＴ１（例えば、１．０ｍｍ）よりも小さく設定されている。
従って、図８（Ｂ）に示すように、回路基板７２をカバー８０の溝部８６に取り付けると、回路基板７２は、カバー８０の取付体７３に対する取付面８１１から高さＨ１だけ取付体７３側に突出する。ここで、Ｈ１＝Ｔ１−Ｄ１である。
このため、カバー８０を取付体７３に取付ねじ８３５にて取り付けると、回路基板７２の裏面７２２が取付体７３の下面７３８に押し付けられ、回路基板７２と取付体７３との密着性が向上する。
したがって、ＬＥＤ７１の熱を取付体７３から器具本体２０等へ伝達でき十分な放熱を行うことができ、温度上昇に伴うＬＥＤ７１の光束低下や短寿命を防止できる。 That is, as shown in FIG. 8A, the depth D1 (for example, 0.8 mm) of the groove 86 is set to be smaller than the thickness T1 (for example, 1.0 mm) of the circuit board 72.
Therefore, as shown in FIG. 8B, when the circuit board 72 is attached to the groove portion 86 of the cover 80, the circuit board 72 moves from the attachment surface 811 to the attachment body 73 of the cover 80 to the attachment body 73 side by the height H1. Protruding. Here, H1 = T1-D1.
For this reason, when the cover 80 is attached to the attachment body 73 with the attachment screw 835, the back surface 722 of the circuit board 72 is pressed against the lower surface 738 of the attachment body 73, and the adhesion between the circuit board 72 and the attachment body 73 is improved.
Therefore, the heat of the LED 71 can be transmitted from the attachment body 73 to the instrument main body 20 and the like, and sufficient heat radiation can be performed, so that a decrease in luminous flux and a short life of the LED 71 accompanying a temperature rise can be prevented.

図５に示すように、カバー８０における複数のＬＥＤ７１の照射方向前方（すなわち、下方）には、ＬＥＤ７１からの光を配光制御するレンズ８７が各々設けられている。
各レンズ８７は一体的に形成されており、表面８７１はカバー本体８１から下方へ階段状に突出している（図６参照）。
このため、補助光源７０を枠体２２の開口部２２３（図２参照）に取り付ける際に、レンズ８７の表面７２１側の階段状に突出した部分を開口部２２３に嵌合させることにより、容易に補助光源７０の位置決めを行うことができる。 As shown in FIG. 5, lenses 87 for controlling the light distribution of the light from the LEDs 71 are provided in front of the plurality of LEDs 71 in the cover 80 in the irradiation direction (that is, below).
Each lens 87 is integrally formed, and the surface 871 protrudes downward from the cover body 81 in a stepped manner (see FIG. 6).
For this reason, when attaching the auxiliary light source 70 to the opening 223 (see FIG. 2) of the frame body 22, it is easy to fit the opening 223 in a stepped shape on the surface 721 side of the lens 87. The auxiliary light source 70 can be positioned.

図４（Ｂ）に示すように、カバー８０の外側立壁（外壁）８２２とレンズ８７の側面８７２との間に遮光物７４を設けた。
遮光物７４としては、遮光性のあるシート状の部材を用いることができる。あるいは、遮光性のある樹脂等を充填することもできる。 As shown in FIG. 4B, a light shielding member 74 is provided between the outer standing wall (outer wall) 822 of the cover 80 and the side surface 872 of the lens 87.
As the light shield 74, a sheet-like member having a light shielding property can be used. Alternatively, a light-shielding resin or the like can be filled.
