For example, Patent Document 1 describes a light source unit in which a plurality of LEDs are mounted on the surface of a substrate, a heat radiating member that abuts on the back surface of the substrate, a reflector arranged on the front surface side of the substrate, and the light source. It is a lighting fixture having a unit, a fixture body that holds the heat radiation member, and a fixing member that fixes the substrate to the heat radiation member. In this luminaire, the fixing member is provided on the non-reflective surface side of the reflector, the mounting portion attached to the fixture body, and the substrate by elastic force between the reflector and the fixture body. The narrow holding portion is integrally formed.

FIG. 3 is a perspective view in which the light source lid portion 240 is removed from the light source portion 200 shown in FIG.

（照明器具１０００の構成）
図１、図２のように、照明器具１０００（照明装置）は、天井（被取付部）に当接するように設置される本体部１００と、本体部１００に脱着可能に取り付けられる光源部２００から構成される。光源部２００は本体部１００に対向するように脱着可能に取り付けられる。光源部２００の両端は光源蓋部２４０で蓋がされている。 (Structure of lighting equipment 1000)
As shown in FIGS. 1 and 2, the luminaire 1000 (lighting device) is attached to a main body 100 installed so as to abut against the ceiling (attached portion) and a light source 200 detachably attached to the main body 100. It is composed. The light source unit 200 is detachably attached so as to face the main body 100. Both ends of the light source unit 200 are covered with a light source lid unit 240.

図３は光源部２００の斜視図であり、図２の光源部２００から光源蓋部２４０取り外した斜視図である。図４は図３のＡ−Ａ断面である。図３、図４に示すように、光源部２００は、ＬＥＤ基板２１０（光源ユニット）、フレーム２２０、カバー２３０を備える。 FIG. 3 is a perspective view of the light source unit 200, and is a perspective view of the light source unit 240 removed from the light source unit 200 of FIG. FIG. 4 is a cross section taken along the line AA of FIG. As shown in FIGS. 3 and 4, the light source unit 200 includes an LED substrate 210 (light source unit), a frame 220, and a cover 230.

（ＬＥＤ基板）
照明器具１０００（図１）は長手形状であり、ＬＥＤ基板２１０も同様に長手形状である。ＬＥＤ基板２１０には基板２１１の実装面２１１Ｊの長手方向に複数のＬＥＤ２１２が実装されている。 (LED board)
The luminaire 1000 (FIG. 1) has a longitudinal shape, and the LED substrate 210 also has a longitudinal shape. A plurality of LEDs 212 are mounted on the LED board 210 in the longitudinal direction of the mounting surface 211J of the board 211.

（フレーム２２０）
フレーム２２０は、アルミや鉄などの金属で出来ており、ＬＥＤ２１２から出る熱が基板２１１を通してフレーム２２０（フレーム側平坦部２２１）に伝わり、放熱される。フレーム２２０はＬＥＤ基板２１０が固定される固定部材と、ＬＥＤ基板２１０の熱を放熱する放熱部材の機能をする。フレーム２２０は本体部１００とほぼ同じ長さの長手形状をなす（図２）。図４のように、フレーム２２０はＬＥＤ基板２１０の裏面（実装面２１１Ｊの裏側の面）に当接するフレーム側平坦部２２１を有する。フレーム２２０は断面が略「コの字」の形状をなし、長手の長方形形状であるフレーム側平坦部２２１の両側からそれぞれ起立して側面をなす側面板２２２を有する。側面板２２２の切立方向の端部は、フレーム２２０の長手方向にわたって、カール加工がされている（側面板カール部２２２Ｒ）。 (Frame 220)
The frame 220 is made of a metal such as aluminum or iron, and the heat generated from the LED 212 is transferred to the frame 220 (flat portion 221 on the frame side) through the substrate 211 and dissipated. The frame 220 functions as a fixing member to which the LED substrate 210 is fixed and a heat radiating member that dissipates heat from the LED substrate 210. The frame 220 has a longitudinal shape having substantially the same length as the main body 100 (FIG. 2). As shown in FIG. 4, the frame 220 has a frame-side flat portion 221 that abuts on the back surface of the LED substrate 210 (the surface on the back side of the mounting surface 211J). The frame 220 has a substantially "U-shaped" cross section, and has side plates 222 that stand up from both sides of the frame-side flat portion 221 that has a long rectangular shape and form side surfaces. The end portion of the side plate 222 in the cutting direction is curled over the longitudinal direction of the frame 220 (side plate curl portion 222R).

（カバー２３０）
カバー２３０は、ポリカーボネートやアクリルなどの透明または光拡散材を含んだ透光性樹脂でできている。カバー２３０は、一体成形品である。図４のように、カバー２３０は、フレーム側平坦部２２１と接する平板状のカバー側平坦部２３２、ＬＥＤ基板２１０を覆う透光性のカバー側本体部２３３、爪部２３４（カバー側フレーム係合部）を有する。カバー側本体部２３３は、カバー側平坦部２３２から立ち上がってＬＥＤ基板２１０を覆う。それぞれのカバー側平坦部２３２のＬＥＤ基板２１０寄りの端部には、カバー側基板固定部２３２−１が形成されている。またカバー側平坦部２３２の裏面からは長手方向にわたって（図３）、側板形状の爪部２３４が壁状に立設している。爪部先端部２３４Ｒは、側面板カール部２２２Ｒに適合する形状の曲げＲ形状となっている。 (Cover 230)
The cover 230 is made of a translucent resin containing a transparent or light diffusing material such as polycarbonate or acrylic. The cover 230 is an integrally molded product. As shown in FIG. 4, the cover 230 has a flat plate-shaped cover-side flat portion 232 in contact with the frame-side flat portion 221, a translucent cover-side main body portion 233 that covers the LED substrate 210, and a claw portion 234 (cover-side frame engagement). Part). The cover-side main body portion 233 rises from the cover-side flat portion 232 and covers the LED substrate 210. A cover-side substrate fixing portion 232-1 is formed at the end of each cover-side flat portion 232 near the LED substrate 210. Further, from the back surface of the cover-side flat portion 232, a side plate-shaped claw portion 234 is erected in a wall shape from the back surface in the longitudinal direction (FIG. 3). The claw portion tip portion 234R has a bent R shape that matches the side plate curl portion 222R.

（カバー２３０とフレーム２２０の係合）
図５を参照してカバー２３０とフレーム２２０の係合を説明する。カバー２３０をフレーム２２０に係合させる際には、それぞれのカバー側基板固定部２３２−１によって、ＬＥＤ基板２１０の長手方向の端部を押さえた状態で、作業者がカバー２３０の爪部２３４を破線のように弾性変形させて広げて、カバー２３０の爪部２３４をフレーム２２０の側面板２２２に係合させる。つまり図４に示す寸法Ｌ１はカバー２３０側における寸法Ｌ１、フレーム２２０側における寸法Ｌ１が考慮され、また寸法Ｌ２はＬＥＤ基板２１０の板厚が考慮されてカバー側基板固定部２３２−１のカバー側平坦部２３２に対する段差寸法（カバー２３０側の寸法Ｌ２）が決められる。これらの寸法関係によってＬＥＤ基板２１０は、カバー側基板固定部２３２−１により、フレーム２２０（フレーム側平坦部２２１）に押さえつけられて固定されると共に、ＬＥＤ２１２から出た熱を効率よくフレーム２２０に伝えることが可能となる。なおＬＥＤ基板２１０はカバー２３０だけで固定してもよいが、ＬＥＤ基板２１０とフレーム２２０（フレーム側平坦部２２１）との間にシリコンなどの熱伝導の良い接着剤を塗布して接着し、カバー２３０で固定してもよい。 (Engagement of cover 230 and frame 220)
The engagement between the cover 230 and the frame 220 will be described with reference to FIG. When engaging the cover 230 with the frame 220, the operator holds the claw portion 234 of the cover 230 while pressing the longitudinal end of the LED substrate 210 by the respective cover-side substrate fixing portions 232-1. It is elastically deformed and expanded as shown by the broken line, and the claw portion 234 of the cover 230 is engaged with the side plate 222 of the frame 220. That is, the dimension L1 shown in FIG. 4 takes into consideration the dimension L1 on the cover 230 side and the dimension L1 on the frame 220 side, and the dimension L2 takes into consideration the thickness of the LED substrate 210 and the cover side of the cover side substrate fixing portion 232-1. The step dimension (dimension L 2 on the cover 230 side) with respect to the flat portion 232 is determined. Due to these dimensional relationships, the LED substrate 210 is pressed and fixed to the frame 220 (frame-side flat portion 221) by the cover-side substrate fixing portion 232-1, and the heat generated from the LED 212 is efficiently transferred to the frame 220. It becomes possible. The LED substrate 210 may be fixed only by the cover 230, but the cover is adhered by applying an adhesive having good thermal conductivity such as silicon between the LED substrate 210 and the frame 220 (flat portion 221 on the frame side). It may be fixed at 230.

以上の実施の形態１の照明器具１０００は、カバー２３０の一部がＬＥＤ基板を押さえる構成であることが特徴である。カバー２３０は一体成形品であり、放熱部材であるフレーム２２０にはまり込むことで固定される。フレーム２２０に固定される再に、カバー２３０の一部（爪部）がＬＥＤ基板を固定する機能を有しており、カバー２３０をフレーム（放熱部材）にはめ込むという一つの操作でＬＥＤ基板２１０を固定することができる。よって、部品点数の削減や、作業工数の削減などの効果がある。 The luminaire 1000 according to the first embodiment is characterized in that a part of the cover 230 presses the LED substrate. The cover 230 is an integrally molded product, and is fixed by being fitted into a frame 220 which is a heat radiating member. A part (claw part) of the cover 230 has a function of fixing the LED board to the frame 220, and the LED board 210 can be mounted by one operation of fitting the cover 230 into the frame (heat dissipation member). Can be fixed. Therefore, there are effects such as reduction of the number of parts and reduction of work man-hours.

実施の形態２．
図６は、本実施の形態２におけるＡ−Ａ断面図（実施の形態１の図３のＡ−Ａ断面）を示す。図６に示すように、ＬＥＤ２１２から出た光はカバー側本体部２３３を通して発光する光１と、カバー内面（Ｐ点）で反射する光２がある。カバー側本体部２３３の内面（Ｐ点）で反射した光２は、カバー内側のカバー側平坦部２３２（カバー側基板固定部２３２−１を含む）（Ｑ点）で再度反射してカバー側本体部２３３から発光される。ここで、カバー２３０のうち、内部反射面となるカバー側平坦部２３２を、カバー側本体部２３３よりも反射率の大きい高反射材料（カバー側平坦部２３２Ａ、カバー側基板固定部２３２−１Ａ）にすることにより、カバー２３０からの発光効率を上げることができる。高反射材料はカバー側本体部２３３の透光材料と同質の材料、例えばポリカーボネートであり、２種類の材料を一体成形で押出すことができる。また、基板１１の表面に高反射材料を塗布すれば、更に光学効率を上げることができる。 Embodiment 2.
FIG. 6 shows a cross-sectional view taken along the line AA in the second embodiment (cross-sectional view taken along the line AA in FIG. 3 of the first embodiment). As shown in FIG. 6, the light emitted from the LED 212 includes a light 1 emitted through the cover side main body 233 and a light 2 reflected by the inner surface (point P) of the cover. The light 2 reflected by the inner surface (point P) of the cover-side main body 233 is reflected again by the cover-side flat portion 232 (including the cover-side substrate fixing portion 232-1) (point Q) inside the cover, and the cover-side main body. Light is emitted from unit 233. Here, of the cover 230, the cover-side flat portion 232, which is the internal reflective surface, is made of a highly reflective material having a higher reflectance than the cover-side main body portion 233 (cover-side flat portion 232A, cover-side substrate fixing portion 232-1A). By setting this, the light emission efficiency from the cover 230 can be increased. The highly reflective material is a material of the same quality as the translucent material of the cover side main body 233, for example, polycarbonate, and two kinds of materials can be extruded by integral molding. Further, if a highly reflective material is applied to the surface of the substrate 11, the optical efficiency can be further improved.

実施の形態２の照明器具は、カバー２３０が２種類の樹脂材料で一体成形されており、発光部分（カバー側本体部２３３）は光透過性材料からなり、反射部分（カバー側基板固定部２３２−１を含むカバー側平坦部２３２）には反射率９０％以上の高反射材料を使用する。これにより、光の取り出し効率を向上させる効果がある。 In the lighting fixture of the second embodiment, the cover 230 is integrally molded with two kinds of resin materials, the light emitting portion (cover side main body portion 233) is made of a light transmitting material, and the reflective portion (cover side substrate fixing portion 232). A highly reflective material having a reflectance of 90% or more is used for the cover-side flat portion 232) including -1. This has the effect of improving the light extraction efficiency.

なお、実施の形態１〜３は、全てまたは部分的に組み合わせてもよい。 As shown in FIGS. 7 and 8, protrusions 232-1-1 are provided on the surface (location) of the cover-side substrate fixing portion 232-1 that comes into contact with the mounting surface 211J of the substrate 211. The protrusion 232-1-1 can reliably press the substrate 211 against the frame 220 (frame-side flat portion 221). The protrusions 232-1-1 have a longitudinal shape along a plurality of LEDs in FIG.
In addition, the first to third embodiments may be combined in whole or in part.
