Each light emitting diode 20 lights up by supplying. The lighting device 5 of the present embodiment is provided with three terminal blocks 50 as shown in FIG. For this reason, since the lighting power of each light emitting diode 20 can be supplied to the three light source units 2 by one lighting device 5, it is not necessary to install a plurality of lighting devices, and the space inside the fixture body 1 is effectively used. Can be used. Needless to say, the number of terminal blocks 50 is not limited to three, and may be increased or decreased according to the power supply capacity of the lighting device 5.

光源ユニット２の下方には、図３（ａ）に示すように光源ユニット２の下面を覆う略矩形状の鋼板から成る反射板３が設けられている。反射板３の各発光ダイオード２０と対向する位置には、上方から下方にかけて拡開した略円錐台形状の窪みが設けられている。また、各窪みの上底面には、発光ダイオード２０を下方に臨ませるための丸孔（図示せず）が貫設されている。而して、発光ダイオード２０から放射される光が反射板３の窪みで反射して下方へ配光制御される。尚、反射板３の左右両側の上端部には、それぞれ左右外側に延設された延設片３０が一体に形成されており、各延設片３０には取付台１４の第２の取付孔１４ｄと略同一寸法のねじ挿通孔（図示せず）が貫設されている。このため、各ねじ挿通孔を第２の取付孔１４ｄと合わせ、組立ねじを挿通して螺合することで反射板３が器具本体１に取り付けられる。   Below the light source unit 2, as shown in FIG. 3A, a reflector 3 made of a substantially rectangular steel plate that covers the lower surface of the light source unit 2 is provided. In a position of the reflecting plate 3 facing each light emitting diode 20, a substantially frustoconical recess that is expanded from above to below is provided. In addition, a round hole (not shown) for allowing the light emitting diode 20 to face downward is provided through the upper bottom surface of each recess. Thus, the light emitted from the light emitting diode 20 is reflected by the recess of the reflector 3 and the light distribution is controlled downward. The upper and lower ends of the reflecting plate 3 are integrally formed with extension pieces 30 extending outwardly on the left and right sides, and each extension piece 30 has a second mounting hole of the mounting base 14. A screw insertion hole (not shown) having substantially the same dimensions as 14d is provided therethrough. For this reason, the reflector 3 is attached to the instrument main body 1 by aligning each screw insertion hole with the second attachment hole 14d and inserting and screwing the assembly screw.

Further, a bearing 71 into which the shaft portion 41 b of the spring member 41 is inserted is provided at a substantially central portion of the standing piece 70.

ルーバ枠４又は化粧板７を器具本体１に取り付ける場合には、先ず、ばね部材４１をコイル部４１ａを上方に向けた状態で器具本体１のばね引掛部１５の折曲部位１５ａに押し付ける。すると、湾曲部４１ｃが折曲部位１５ａに摺動して内側に撓んだ状態でばね引掛部１５の上方に挿通される。そして、挿通された湾曲部４１ｃが復帰して、その頂部がばね引掛部１５の折曲部位１５ａよりも外側に突出することで折曲部位１５ａに係合し、ルーバ枠４又は化粧板７が器具本体１に取り付けられる（図３（ａ）参照）。   When attaching the louver frame 4 or the decorative plate 7 to the instrument body 1, first, the spring member 41 is pressed against the bent portion 15 a of the spring hook 15 of the instrument body 1 with the coil portion 41 a facing upward. Then, the bending portion 41c is inserted above the spring hooking portion 15 in a state where the bending portion 41c slides on the bending portion 15a and is bent inward. Then, the inserted curved portion 41c is restored, and the top portion protrudes outward from the bent portion 15a of the spring hooking portion 15, so that the bent portion 15a is engaged with the louver frame 4 or the decorative plate 7. It attaches to the instrument main body 1 (refer Fig.3 (a)).

上述のように、１つの器具本体１の内部を９つの区画に分け、各区画に光源ユニット２及び化粧板７を着脱自在に取り付けることができるので、何れの区画に光源ユニット２及び化粧板７を取り付けるかを自由に決定することができ、従来例と比較して照明空間のレイアウトを自由に変更することができる。例えば、図５（ａ）に示すように、左右両側の区画にそれぞれ前後方向に沿って３つずつ光源ユニット２及びルーバ枠４を取り付け、その他の区画に化粧板７を取り付けるレイアウトが考えられる。また、図５（ｂ）に示すように、四隅の区画に光源ユニット２及びルーバ枠４を取り付け、その他の区画に化粧板７を取り付けるレイアウトが考えられる。また、図５（ｃ）に示すように、四隅の区画に化粧板７を取り付け、その他の区画に光源ユニット２及びルーバ枠４を取り付けるレイアウトも考えられる。   As described above, the inside of one appliance main body 1 is divided into nine sections, and the light source unit 2 and the decorative board 7 can be detachably attached to each section. Therefore, the light source unit 2 and the decorative board 7 can be attached to any section. Can be freely determined, and the layout of the illumination space can be freely changed as compared with the conventional example. For example, as shown in FIG. 5A, a layout in which three light source units 2 and three louver frames 4 are attached along the front-rear direction to the left and right side sections, and a decorative plate 7 is attached to the other sections. Moreover, as shown in FIG.5 (b), the layout which attaches the light source unit 2 and the louver frame 4 to four corner divisions, and attaches the decorative board 7 to other divisions can be considered. Moreover, as shown in FIG.5 (c), the layout which attaches the decorative board 7 to the division of four corners, and attaches the light source unit 2 and the louver frame 4 to another division is also considered.

尚、本実施形態では図１に示すように、四隅の区画に配設された光源ユニット２は反射板３及びルーバ４０の丸孔を介して発光ダイオード２０から下方へ光を照射する構成であり、残りの２区画に配設された光源ユニット２は略矩形状の集光レンズ２４を発光ダイオード２０の下側に設けた構成となっている。このため、四隅の区画では光が区画全体に広がるような照明を演出することができ、残りの２区画では発光ダイオード２０の周部が強調された照明を演出することができる。また、本実施形態では１つの器具本体１の内部を９つの区画に分けているが、区画数がこれに限定される必要が無いのは言うまでもない。   In the present embodiment, as shown in FIG. 1, the light source unit 2 disposed in the four corner sections is configured to irradiate light downward from the light emitting diode 20 through the reflector 3 and the round hole of the louver 40. The light source unit 2 disposed in the remaining two sections has a configuration in which a substantially rectangular condensing lens 24 is provided below the light emitting diode 20. For this reason, illumination in which light spreads over the entire compartment can be produced in the four corner sections, and illumination in which the peripheral portion of the light emitting diode 20 is emphasized can be produced in the remaining two sections. Moreover, in this embodiment, although the inside of one instrument main body 1 is divided into nine divisions, it cannot be overemphasized that the number of divisions does not need to be limited to this.
