The power supply case 35 is positioned at a predetermined position of the bottom plate portion 24 by fitting the claw portion 20 of the power supply case 35 into a notch 24 e provided in the bottom plate portion 24. The power supply case 35 is fixed by being sandwiched between the instrument main body 21 and the instrument upper cover 61.

図11に示すように、給電側コネクタ保持部35eは、取付部71に対向する第1周壁部35bにおいて取付部71に向けて凸状に突出した部分である。図7に示すように、給電側コネクタ保持部35eは、電源回路配置部36に連通した部分であり、有底状で上端が開放されている。給電側コネクタ保持部35eには、給電側コネクタ34を挿通するための挿通孔35fを有している。電源回路部32から配線を介して延出される給電側コネクタ34は、給電側コネクタ保持部35eにより挿通孔35fからとび出した状態で保持される。

チャンネル切替スイッチ部38は、周壁部25に対向する第3周壁部35dの長手方向の中央部に設けられ、器具本体21の貫通孔25aから露出される側面視略四角状の部分である。チャンネル切替スイッチ部38は、電源ケース35内に電源基板33が配置されたとき、チャンネル切替スイッチ83が配置される部分である。チャンネル切替スイッチ部38は、上端に径方向外側に張り出した張出部38aと、張出部38aの下部にチャンネル切替スイッチ83の先端部を露出するための貫通孔38bとを有している。チャンネル切替スイッチ部38は、器具本体21の貫通孔25aに組み合わされて、チャンネル切替スイッチ部38が周壁部25の側面に露出される。チャンネル切替スイッチ部38の露出部分は、周壁部25の傾斜にほぼ沿って傾斜し、ユーザーが下方から視認し易いように形成されている。このように、チャンネル切替スイッチ部38が器具本体21の貫通孔25aを介して照射面側に露出するため、チャンネル設定作業がしやすい。
なお、電源基板33は実装面に複数の電気部品が実装されているが、図3等においては電源基板33の構成を明瞭に図示するために電気部品の一部の図示は省略した。また、本実施形態のチャンネル切替スイッチ部38は、本発明におけるチャンネル切替スイッチ部の一例である。チャンネル切替スイッチ部は、その形状や、電源ケースに設けられる位置などを適宜変更してもよい。
The channel changeover switch portion 38 is provided at the center portion in the longitudinal direction of the third peripheral wall portion 35 d facing the peripheral wall portion 25, and is a substantially rectangular portion in side view exposed from the through hole 25 a of the instrument main body 21. The channel changeover switch unit 38 is a part where the channel changeover switch 83 is arranged when the power supply board 33 is arranged in the power supply case 35. The channel changeover switch part 38 has an overhanging part 38a projecting radially outward at the upper end, and a through hole 38b for exposing the tip of the channel changeover switch 83 below the overhanging part 38a. The channel changeover switch part 38 is combined with the through hole 25 a of the instrument body 21, and the channel changeover switch part 38 is exposed on the side surface of the peripheral wall part 25. The exposed portion of the channel changeover switch portion 38 is inclined substantially along the inclination of the peripheral wall portion 25 so that the user can easily see from below. Thus, since the channel changeover switch part 38 is exposed to the irradiation surface side through the through hole 25a of the instrument main body 21, the channel setting work is easy.
The power supply board 33 has a plurality of electric components mounted on the mounting surface. However, in FIG. 3 and the like, some of the electric components are not shown in order to clearly show the configuration of the power supply board 33. The channel changeover switch unit 38 of the present embodiment is an example of the channel changeover switch unit in the present invention. The shape of the channel changeover switch unit and the position provided in the power supply case may be changed as appropriate.

このように電源部31を構成することで、電源回路部32(電源基板33)と、受信部81(受光素子82、チャンネル切替スイッチ83)と、給電側コネクタ34と、を一体化して1ユニット化している。電源部31は、先ず、爪部20が器具本体21の底板部24に設けられた切欠き部24eに係止される。チャンネル切替スイッチ部38は、器具本体21の照射面側において、張出部38aが器具本体21の鍔部27の内周端部に係止された状態で配置される。器具本体21に電源部31を配置した状態で、器具上部カバー61が器具本体21に取り付けられる。器具本体21に器具上部カバー61が取り付けられることで、電源部31は器具本体21と器具上部カバー61とで挟持されて固定される。その際に、給電側コネクタ部37(給電側コネクタ保持部35e)は、取付部71の後述する給電側コネクタガイド部76に組み合わされる。また、チャンネル切替スイッチ部38が器具本体21の貫通孔25aに組み合わされる。
これにより、給電側コネクタ34は、取付部71の内部に露出するように取り付けられる。また、チャンネル切替スイッチ部38は、周壁部25の側面に露出するように取り付けられる。照明器具11を天井等の取付面に取り付ける際、給電側コネクタ34は、取付部71の内部に配置された状態で、配線器具側のコネクタ(図示せず)に接続することで、電源回路部32は照明器具用の天井配線器具を介して外部商用電源と電気的に接続される。こうして、電源回路部32(電源基板33)、受信部81(受光素子82、チャンネル切替スイッチ83)、及び給電側コネクタ34は、電源ケース35を介して器具本体21の収容部26に1ユニットとして取り付けられる。
By configuring the power supply unit 31 in this way, the power supply circuit unit 32 (power supply board 33), the reception unit 81 (light receiving element 82, channel changeover switch 83), and the power supply side connector 34 are integrated into one unit. It has become. As for the power supply part 31, the nail | claw part 20 is first latched by the notch part 24e provided in the baseplate part 24 of the instrument main body 21. FIG. The channel changeover switch unit 38 is arranged on the irradiation surface side of the instrument main body 21 in a state where the overhanging part 38 a is locked to the inner peripheral end of the flange part 27 of the instrument main body 21. The instrument upper cover 61 is attached to the instrument main body 21 in a state where the power supply unit 31 is disposed on the instrument main body 21. By attaching the appliance upper cover 61 to the appliance main body 21, the power source 31 is sandwiched and fixed between the appliance main body 21 and the appliance upper cover 61. At that time, the power supply side connector portion 37 (power supply side connector holding portion 35e) is combined with a power supply side connector guide portion 76 described later of the attachment portion 71. Further, the channel changeover switch unit 38 is combined with the through hole 25 a of the instrument main body 21.
As a result, the power supply side connector 34 is attached so as to be exposed inside the attachment portion 71. Further, the channel changeover switch portion 38 is attached so as to be exposed on the side surface of the peripheral wall portion 25. When attaching the lighting fixture 11 to a mounting surface such as a ceiling, the power supply side connector 34 is connected to a wiring fixture side connector (not shown) in a state of being disposed inside the mounting portion 71, thereby providing a power supply circuit portion. 32 is electrically connected to an external commercial power source via a ceiling wiring fixture for lighting fixtures. In this way, the power supply circuit unit 32 (power supply board 33), the reception unit 81 (light receiving element 82, channel changeover switch 83), and the power supply side connector 34 are arranged as one unit in the housing unit 26 of the instrument body 21 via the power supply case 35. It is attached.

また、電源回路部32は、上記のように、電源ケース35に収容されるため、電源回路部32と器具本体21との間で電気的絶縁性を確保できる。また、電源ケース35を用いて、電源回路部32(電源基板33)、受信部81(受光素子82、チャンネル切替スイッチ83)、及び給電側コネクタ34を電源部31として1ユニット化することによって、これらを同時に器具本体21及び取付部71に容易に取り付けることができ、照明器具11の組立性が向上する。すなわち、照明器具11の組立作業の簡素化を可能とする。また、電源ケース35を用いて電源回路部32(電源基板33)、受信部81(受光素子82、チャンネル切替スイッチ83)、及び給電側コネクタ34を一体化して1ユニットにする作業工程と、当該1ユニットを器具本体21に取り付ける作業工程とを分業化することが可能となり、生産性が向上する。   Moreover, since the power supply circuit part 32 is accommodated in the power supply case 35 as described above, electrical insulation can be ensured between the power supply circuit part 32 and the instrument main body 21. Further, by using the power supply case 35, the power supply circuit unit 32 (power supply board 33), the reception unit 81 (light receiving element 82, channel changeover switch 83), and the power supply side connector 34 are integrated into one unit as the power supply unit 31. These can be easily attached to the fixture main body 21 and the attachment portion 71 at the same time, and the assemblability of the lighting fixture 11 is improved. That is, the assembling work of the lighting fixture 11 can be simplified. In addition, the power supply case 35 is used to integrate the power supply circuit section 32 (power supply board 33), the reception section 81 (light receiving element 82, channel switch 83), and the power supply side connector 34 into one unit, The work process for attaching one unit to the instrument main body 21 can be divided and the productivity can be improved.

また、電源ケース35は、取付面側が開放されており、電源基板33の一面側(取付面側)が露出している。これにより、電源回路部32から発生する熱は、電源ケース35の内部に籠ることがない。また、電源ケース35は、器具上部カバー61に対向する側が開放されているため、熱が器具上部カバー61を介して外部に放熱されることで、放熱性が向上する。   Further, the power supply case 35 is open on the mounting surface side, and one surface side (mounting surface side) of the power supply substrate 33 is exposed. Thereby, the heat generated from the power supply circuit unit 32 does not go inside the power supply case 35. In addition, since the power supply case 35 is open on the side facing the instrument upper cover 61, heat is radiated to the outside through the instrument upper cover 61, thereby improving heat dissipation.

光源部41は、照明器具11の照射面側に向けて光を出射する部分である。光源部41は、器具本体21の凸部(収容部26の照射面側の部分)に配置される。光源部41は、複数のLED素子42を有する。光源部41は、底板部24の照射面側の光源取付部24a上に配置される平板状のものである。光源取付部24aは、平坦な表面を有する。具体的には、光源部41は、複数(本実施形態では、2枚)のLED光源モジュール44を有している。各LED光源モジュール44は、平板状モジュール基板である基板43(43a、43b)上に複数の点光源であるLED素子42が実装されて構成されている。複数のLED素子42は、器具本体21の開口部22を中心として略同心円状に略等間隔で配置されている。LED光源モジュール44は、器具本体21が有する保持部29よりも照射面側の位置に配置される。これにより、透光性カバー51に保持部29の影が出にくい。   The light source unit 41 is a part that emits light toward the irradiation surface side of the lighting fixture 11. The light source unit 41 is disposed on the convex portion of the instrument main body 21 (the portion on the irradiation surface side of the housing portion 26). The light source unit 41 includes a plurality of LED elements 42. The light source unit 41 is a flat plate disposed on the light source mounting part 24 a on the irradiation surface side of the bottom plate part 24. The light source mounting portion 24a has a flat surface. Specifically, the light source unit 41 includes a plurality (two in this embodiment) of LED light source modules 44. Each LED light source module 44 is configured by mounting a plurality of LED elements 42 as point light sources on a substrate 43 (43a, 43b) as a flat module substrate. The plurality of LED elements 42 are arranged in substantially concentric circles at substantially equal intervals around the opening 22 of the instrument body 21. The LED light source module 44 is disposed at a position closer to the irradiation surface than the holding portion 29 of the instrument main body 21.
