（照明器具の構成）
図３、図４等に示すように、照明器具１００は、反射板２（器具本体）と、反射板２に収納される光源取付金具３（光源取付部）と、光源取付金具３に取り付けられる電源取付金具４（電源取付部）とを備えている。光源取付金具３と電源取付金具４とは、反射板２に収納される。既設シャーシ１は、蛍光灯用の照明器具の転用品である。照明器具１００は、蛍光灯用の照明器具をＬＥＤ用に転用した器具である。図３において透光カバー８を取り外すと、ＬＥＤユニット３５０ａ，３５０ｂ・・・３５０ｎ（光源ユニットという場合もある）が配置されている。なお、ＬＥＤを発光体として用いるのは一例であり、ＯＬＥＤや他の発光体を用いてユニット化してもよい。 (Structure of lighting equipment)
As shown in FIGS. 3, 4, etc., the lighting fixture 100 is attached to the reflecting plate 2 (the fixture body), the light source mounting bracket 3 (light source mounting portion) housed in the reflecting plate 2, and the light source mounting bracket 3. A power supply mounting bracket 4 (power supply mounting portion) is provided. The light source mounting bracket 3 and the power source mounting bracket 4 are housed in the reflector 2. The existing chassis 1 is a replacement for a lighting fixture for a fluorescent lamp. The luminaire 100 is a fixture obtained by diverting a luminaire for a fluorescent lamp to an LED. 3, when the translucent cover 8 is removed, LED units 350a, 350b... 350n (sometimes referred to as light source units) are arranged. In addition, using LED as a light-emitting body is an example, and you may unitize using OLED and another light-emitting body.

（照明器具１００の組付関係）
既設シャーシ１は既に天井に配置されている。電源取付金具４は、図１、図２に示すように、光源取付金具３にネジ６ａ，６ｂで取り付けられる。光源取付金具３は、図３、図４に示すように、反射板２に、ねじ１０ａ，１０ｂで取り付けられる。そして、反射板２は、図３、図４に示すように金具５ａ，５ｂで既設シャーシ１に取り付けられる。金具５ａ，５ｂがねじ７で締め付けられることによって、反射板２が既設シャーシ１に取り付く。なお、本実施の形態では、既設シャーシ１を転用品と想定しているが、新規のものであっても構わない。 (Assembly relationship of lighting apparatus 100)
The existing chassis 1 is already arranged on the ceiling. The power supply mounting bracket 4 is attached to the light source mounting bracket 3 with screws 6a and 6b as shown in FIGS. As shown in FIGS. 3 and 4, the light source mounting bracket 3 is attached to the reflector 2 with screws 10 a and 10 b. The reflector 2 is attached to the existing chassis 1 with metal fittings 5a and 5b as shown in FIGS. When the metal fittings 5 a and 5 b are tightened with the screws 7, the reflector 2 is attached to the existing chassis 1. In the present embodiment, the existing chassis 1 is assumed to be a transfer product, but it may be a new one.

（反射板２）
反射板２は金属製である。反射板２は、図３、図４に示すように、長手方向に延びて内部に空間を有する蛍光灯用の逆富士形と同形状の反射板であり、発光面には開口２０４がある。反射板２は、図２、図６に示すように、反射面として機能する一方の斜面２０１と、反射面として機能する他方の斜面２０２とを有する。 (Reflector 2)
The reflector 2 is made of metal. As shown in FIGS. 3 and 4, the reflecting plate 2 is a reflecting plate having the same shape as an inverted Fuji shape for a fluorescent lamp extending in the longitudinal direction and having a space inside, and has an opening 204 on the light emitting surface. As shown in FIGS. 2 and 6, the reflecting plate 2 has one inclined surface 201 that functions as a reflecting surface and the other inclined surface 202 that functions as a reflecting surface.

（光源取付金具３）
図６も参照して説明する。光源取付金具３は金属製である。光源取付金具３は、反射板２の内部の空間に配置され、反射板２の長手方向に延びる長尺形状である。光源取付金具３は、反射板２の長手方向にわたって反射板２の一方の斜面２０１の裏側の面に対向する第１の斜面３０１と、反射板２の長手方向にわたって他方の斜面２０２の裏側の面に対向する第２の斜面３０２とが、それぞれ一方の斜面２０１の裏側の面と他方の斜面２０２の裏側の面とに熱的に接続（範囲５１、５２）している。「熱的に接続する」とは、この場合、光源取付金具３と反射板２とが面接触することで、熱が伝導することを意味する。光源取付金具３は、反射板２の外部に向けて光を放つ光源ユニット３５０が取り付けられる。 (Light source mounting bracket 3)
This will be described with reference to FIG. The light source mounting bracket 3 is made of metal. The light source mounting bracket 3 is disposed in a space inside the reflecting plate 2 and has a long shape extending in the longitudinal direction of the reflecting plate 2. The light source mounting bracket 3 includes a first inclined surface 301 facing the back surface of one inclined surface 201 of the reflecting plate 2 over the longitudinal direction of the reflecting plate 2, and a back surface of the other inclined surface 202 along the longitudinal direction of the reflecting plate 2. The second slope 302 facing each other is thermally connected (range 51, 52) to the back surface of one slope 201 and the back surface of the other slope 202, respectively. In this case, “thermally connected” means that the light source mounting bracket 3 and the reflector 2 are in surface contact with each other so that heat is conducted. A light source unit 350 that emits light toward the outside of the reflector 2 is attached to the light source mounting bracket 3.

（電源取付金具４）
電源取付金具４は金属製である。電源取付金具４は、光源取付金具３に取り付けられて光源取付金具３と熱的に接続する。ここで「熱的に接続する」とは、上記のとおりである。電源取付金具４は、反射板２の長手方向に延びる長尺形状であり、光源ユニット３５０を点灯させる新規電源装置１１（電源装置）が取り付けられている。なお、図３に示すように、既設シャーシ１には既設電源９が取り付けられている。既設電源９は既設シャーシ１や反射板２を蛍光灯用に使用した際の電源装置であり、新規電源装置１１は、既設シャーシ１や反射板２をＬＥＤ又はＯＬＥＤ用に転用する際の電源装置である。 (Power supply bracket 4)
The power supply mounting bracket 4 is made of metal. The power supply mounting bracket 4 is attached to the light source mounting bracket 3 and thermally connected to the light source mounting bracket 3. Here, “thermally connecting” is as described above. The power supply mounting bracket 4 has a long shape extending in the longitudinal direction of the reflection plate 2, and a new power supply device 11 (power supply device) for lighting the light source unit 350 is attached. As shown in FIG. 3, an existing power source 9 is attached to the existing chassis 1. The existing power supply 9 is a power supply device when the existing chassis 1 and the reflector 2 are used for fluorescent lamps, and the new power supply device 11 is a power supply device when the existing chassis 1 and the reflector 2 are diverted for LED or OLED. It is.

（空気層）
図６、図４に示すように、光源取付金具３は、平板を折り曲げた折曲形状である。光源取付金具３は、第１の斜面３０１に対応する第１の側板３１０と、第２の斜面３０２に対応する第２の側板３２０と、第１の側板３１０と第２の側板３２０とに対して底面に相当する底板３３０とを含む折曲形状である。電源取付金具４は、底板３３０の上面との間に空間４０１を保って底板３３０の上面を覆いながら反射板２の長手方向に延びることで空間４０１を形成している。すなわち、光源取付金具３と電源取付金具４との間には空間４０１による空気層が存在するので、光源取付金具３が電源取付金具４からもらう「もらい熱」が減少する効果がある。 (Air layer)
As shown in FIGS. 6 and 4, the light source mounting bracket 3 has a bent shape in which a flat plate is bent. The light source mounting bracket 3 has a first side plate 310 corresponding to the first inclined surface 301, a second side plate 320 corresponding to the second inclined surface 302, and the first side plate 310 and the second side plate 320. And a bottom plate 330 corresponding to the bottom surface. The power supply fitting 4 forms a space 401 by extending in the longitudinal direction of the reflection plate 2 while keeping the space 401 between the power supply fitting 4 and the upper surface of the bottom plate 330 and covering the upper surface of the bottom plate 330. That is, since an air layer is formed by the space 401 between the light source mounting bracket 3 and the power supply mounting bracket 4, there is an effect of reducing the “getting heat” that the light source mounting bracket 3 receives from the power supply mounting bracket 4.

（放熱ルート）
光源取付金具３に取り付けられた新規電源装置１１に発生する熱の放熱ルートは以下の様である。新規電源装置１１で発生した熱は、新規電源装置１１→電源取付金具４→光源取付金具３→反射板２の順に伝導する。この際、光源取付金具３は、反射板２の反射面と面接触している。すなわち、上述のように、光源取付金具３は、第１の斜面３０１と、第２の斜面３０２とが、一方の斜面２０１の裏側の面と他方の斜面２０２の裏側の面とに熱的に接続している。この場合、図６のように、反射板２の一方の斜面２０１及び他方の斜面２０２は、天井面に対して傾斜（θは９０度よりも大きい）しているため、この付近は空気が流れやすくなっている。このため、一方の斜面２０１及び他方の斜面２０２付近の放熱効果はよい。 (Heat dissipation route)
The heat radiation route of heat generated in the new power supply device 11 attached to the light source mounting bracket 3 is as follows. The heat generated in the new power supply device 11 is conducted in the order of the new power supply device 11 → the power supply mounting bracket 4 → the light source mounting bracket 3 → the reflection plate 2. At this time, the light source mounting bracket 3 is in surface contact with the reflecting surface of the reflecting plate 2. That is, as described above, in the light source mounting bracket 3, the first inclined surface 301 and the second inclined surface 302 are thermally applied to the surface on the back side of the one inclined surface 201 and the surface on the back side of the other inclined surface 202. Connected. In this case, as shown in FIG. 6, one inclined surface 201 and the other inclined surface 202 of the reflector 2 are inclined with respect to the ceiling surface (θ is greater than 90 degrees), so that air flows in this vicinity. It has become easier. For this reason, the heat dissipation effect near one slope 201 and the other slope 202 is good.

（光源ユニットの配置）
また、図３に示すように、反射板２には、逆富士形の頂上に相当する部分２０３に長手方向に向かう開口２０４（図３で透光カバー８が反射板２から露出している部分）が形成されている。また、光源取付金具３には、複数の光源ユニット３５０ａ〜３５０ｎが、開口２０４の側に反射板２の長手方向に並んで取り付けられる。図３のように照明器具１００は、複数のＬＥＤユニットを覆う透光性の透光カバー８を備えている。 (Arrangement of light source unit)
Further, as shown in FIG. 3, the reflector 2 has an opening 204 in the longitudinal direction toward the portion 203 corresponding to the top of the inverted Fuji shape (the portion where the translucent cover 8 is exposed from the reflector 2 in FIG. 3). ) Is formed. A plurality of light source units 350 a to 350 n are attached to the light source mounting bracket 3 side by side in the longitudinal direction of the reflection plate 2 on the opening 204 side. As shown in FIG. 3, the luminaire 100 includes a translucent translucent cover 8 that covers a plurality of LED units.

（４）ＬＥＤやＯＬＥＤを照明器具に用いた際、発光面の角度により天井面に光が当たらないため、空間の印象が暗くなる傾向があるが、カバー形状を変更することにより、天井面や器具自体に光を当てることや、光源との距離を調節することにより、グレア感を抑えることができる。 The following effects are acquired by the lighting fixture 100 demonstrated in the above embodiment.
(1) The cost of equipment replacement can be reduced. In addition, the load on the operator can be reduced.
(2) Since existing members are used, resource saving can be achieved.
(3) Since the heat from the power source is dissipated, the life of the instrument can be extended.
(4) When an LED or OLED is used in a lighting fixture, the ceiling surface does not receive light depending on the angle of the light emitting surface, so the impression of the space tends to be dark, but by changing the cover shape, Glare can be suppressed by applying light to the device itself or adjusting the distance to the light source.
