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 lighting fixture 1000 (FIG. 1) has a longitudinal shape, and the LED substrate 210 has a longitudinal shape as well. A plurality of LEDs 212 are mounted on the LED substrate 210 in the longitudinal direction of the mounting surface 211J of the substrate 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 heat generated from the LED 212 is transmitted to the frame 220 (frame side flat portion 221) through the substrate 211 to be radiated. The frame 220 functions as a fixing member to which the LED substrate 210 is fixed and a heat radiating member that radiates heat from the LED substrate 210. The frame 220 has a longitudinal shape 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 against the back surface of the LED substrate 210 (the surface on the back side of the mounting surface 211J). The frame 220 has a side plate 222 that has a substantially “U” shape in cross section and that stands from both sides of a frame-side flat portion 221 that is a long rectangular shape. The end portion of the side plate 222 in the vertical direction is curled along 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 transparent or transparent resin such as polycarbonate or acrylic or containing a light diffusing material. The cover 230 is an integrally molded product. As shown in FIG. 4, the cover 230 includes a flat cover-side flat portion 232 that contacts 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 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 an end portion of each cover side flat portion 232 near the LED substrate 210. In addition, a side plate-shaped claw portion 234 is erected in a wall shape from the back surface of the cover-side flat portion 232 in the longitudinal direction (FIG. 3). The claw portion tip portion 234R has a bent R shape that fits 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Ｌ１）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 the cover 230 is engaged with the frame 220, the operator holds the claw portion 234 of the cover 230 while holding the end of the LED substrate 210 in the longitudinal direction by the respective cover side substrate fixing portions 232-1. The claws 234 of the cover 230 are engaged with the side plates 222 of the frame 220 by elastically deforming and spreading as shown by broken lines. That is, the dimension L1 shown in FIG. 4 considers the dimension L1 on the cover 230 side and the dimension L1 on the frame 220 side, and the dimension L2 considers the plate thickness of the LED board 210 and covers the cover side substrate fixing portion 232-1 on the cover side. A step size (dimension L1 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 against and fixed to the frame 220 (frame-side flat portion 221) by the cover-side substrate fixing portion 232-1 and efficiently transmits the heat emitted from the LED 212 to the frame 220. It becomes possible. The LED substrate 210 may be fixed only by the cover 230, but an adhesive having a good thermal conductivity such as silicon is applied and adhered between the LED substrate 210 and the frame 220 (frame side flat portion 221). 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 lighting fixture 1000 of the above Embodiment 1 is characterized in that a part of the cover 230 is configured to hold the LED substrate. The cover 230 is an integrally molded product and is fixed by being fitted into the frame 220 which is a heat radiating member. A part (claw part) of the cover 230 has a function of fixing the LED substrate again after being fixed to the frame 220, and the LED substrate 210 is attached by one operation of fitting the cover 230 into the frame (heat radiating member). Can be fixed. Therefore, there are effects such as a reduction in the number of parts and a reduction in 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.
FIG. 6 is a cross-sectional view taken along the line AA in the second embodiment (the AA cross section in FIG. 3 of the first embodiment). As shown in FIG. 6, light emitted from the LED 212 includes light 1 emitted through the cover-side main body 233 and light 2 reflected from the cover inner surface (point P). 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 the unit 233. Here, in the cover 230, the cover-side flat portion 232 serving as an internal reflection surface is made of a highly reflective material (cover-side flat portion 232A, cover-side substrate fixing portion 232-1A) having a higher reflectance than the cover-side main body portion 233. Thus, the light emission efficiency from the cover 230 can be increased. The highly reflective material is the same material as the light-transmitting 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 increased.

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 apparatus of Embodiment 2, the cover 230 is integrally formed of two types of resin materials, the light emitting portion (cover side main body portion 233) is made of a light transmissive material, and the reflecting portion (cover side substrate fixing portion 232). For the cover side flat portion 232 including -1, a highly reflective material having a reflectance of 90% or more is used. This has the effect of improving the light extraction efficiency.
