In addition, an electric wire 253 is connected to the other end of the contact 261, and the other end of the electric wire 253 is connected to an output end of the terminal block 25.

プルスイッチ２６は、図１（ａ）及び図１（ｂ）に示すように引き紐２６２を有し、引き紐２６２を引くことで接点２６１が閉じたり、開いたりする。この引き紐２６２は、器具本体１の一方（図１（ａ）中の左側）の傾斜面１２に設けられた孔１２１を通して吊り下げられた状態にある（図１（ｂ）参照）。   The pull switch 26 has a pull string 262 as shown in FIGS. 1A and 1B, and the contact 261 is closed or opened by pulling the pull string 262. This drawstring 262 is in a state of being suspended through a hole 121 provided in the inclined surface 12 of one side of the instrument body 1 (left side in FIG. 1A) (see FIG. 1B).

そして、引き紐２６２を引いて接点２６１が閉じると、電源線３により供給される交流電力が雌型コネクタ２５１及び雄型コネクタ２４３を介して電源装置２４に入力され、電源装置２４は生成した直流電力を基板２２に供給し、この供給電力によってＬＥＤ２２２が点灯する。また、引き紐２６２を引いて接点２６１が開くと、上記交流電力が電源装置２４に入力されなくなり、電源装置２４から基板２２への給電が停止され、ＬＥＤ２２２が消灯する。つまり、本実施形態の照明器具Ａでは、プルスイッチ２６によってＬＥＤ２２２への給電を入／切する機能（光源に関わる機能）を追加することができ、プルスイッチ２６により機能部品が構成されている。   When the pull string 262 is pulled to close the contact 261, the AC power supplied from the power line 3 is input to the power supply 24 via the female connector 251 and the male connector 243, and the power supply 24 generates the generated DC. Electric power is supplied to the substrate 22, and the LED 222 is lit by this supplied electric power. When the pull string 262 is pulled to open the contact 261, the AC power is not input to the power supply 24, power supply from the power supply 24 to the substrate 22 is stopped, and the LED 222 is turned off. That is, in the lighting fixture A of the present embodiment, a function (function related to the light source) for turning on / off the power supply to the LED 222 by the pull switch 26 can be added, and the pull switch 26 constitutes a functional component.

ここに本実施形態では、端子台２５に接続される電線２５２，２５３により第１電線が構成され、第１電線の先端に設けられた雌型コネクタ２５１により第１コネクタが構成されている。また本実施形態では、電源装置２４に接続される電線２４４により第２電線が接続され、第２電線の先端に設けられた雄型コネクタ２４３により第２コネクタが構成されている。   Here, in the present embodiment, the first electric wire is constituted by the electric wires 252 and 253 connected to the terminal block 25, and the first connector is constituted by the female connector 251 provided at the tip of the first electric wire. In the present embodiment, the second electric wire is connected by the electric wire 244 connected to the power supply device 24, and the second connector is constituted by the male connector 243 provided at the tip of the second electric wire.

次に、光源ユニット２の組立手順について説明する。まず最初に、作業者は、電源装置２４を取付部材２１の底面部２１１の上面側に取り付け、さらに上記係止爪により基板２２を取付部材２１の底面部２１１に固定する。その後、作業者は、基板２２のコネクタ２２３から導出する電線を取付部材２１の底面部２１１に設けた孔２１１ａに通し、その端部を電源装置２４に接続する。   Next, the assembly procedure of the light source unit 2 will be described. First, the operator attaches the power supply device 24 to the upper surface side of the bottom surface portion 211 of the attachment member 21, and further fixes the substrate 22 to the bottom surface portion 211 of the attachment member 21 with the locking claws. Thereafter, the operator passes the electric wire led out from the connector 223 of the board 22 through the hole 211 a provided in the bottom surface portion 211 of the mounting member 21, and connects the end portion to the power supply device 24.

そして最後に、作業者は、開口側を上向きにした状態でカバー部材２３を取付部材２１に組み付ける。このとき、カバー部材２３の各突壁部２３３にそれぞれ設けた突起部２３３ａが、取付部材２１の各側面部２１２にそれぞれ設けた傾斜部２１２ａと係合し、カバー部材２３が取付部材２１に取り付けられる。以上のような手順に従って、光源ユニット２が組み立てられる。   Finally, the operator attaches the cover member 23 to the attachment member 21 with the opening side facing upward. At this time, the protrusions 233 a provided on the respective protruding wall portions 233 of the cover member 23 engage with the inclined portions 212 a provided on the respective side surface portions 212 of the attachment member 21, so that the cover member 23 is attached to the attachment member 21. It is done. The light source unit 2 is assembled according to the above procedure.

続けて、照明器具Ａの施工手順について説明する。なお、以下の説明では、端子台２５及びプルスイッチ２６が予め器具本体１に取り付けられているものとして説明する。まず最初に、作業者は、天井裏に先行配線された電源線３（図１（ａ）参照）を器具本体１の孔１１１ａに通し、さらに室内側に露出する吊ボルト２００を孔１１１ｂに通した後、吊ボルト２００にナット３００をねじ込んで器具本体１を天井材１００に固定する。   Then, the construction procedure of the lighting fixture A is demonstrated. In the following description, it is assumed that the terminal block 25 and the pull switch 26 are attached to the instrument body 1 in advance. First, the operator passes the power line 3 (see FIG. 1 (a)) wired in advance on the back of the ceiling through the hole 111a of the instrument body 1, and further passes the suspension bolt 200 exposed to the indoor side through the hole 111b. After that, the nut 300 is screwed into the suspension bolt 200 to fix the fixture body 1 to the ceiling material 100.

その後、作業者は、電源線３の端部を端子台２５に接続し、さらに端子台２５の雌型コネクタ２５１と電源装置２４の雄型コネクタ２４３を接続する。そして最後に、作業者は、電源装置２４が器具本体１の凹部１１内に収容されるようにして、例えば器具本体１及び取付部材２１にそれぞれ設けた嵌合構造（図示せず）により光源ユニット２を器具本体１に取り付ける。以上のような手順に従って、照明器具Ａが天井に施工される（図４及び図５参照）。   Thereafter, the operator connects the end of the power supply line 3 to the terminal block 25, and further connects the female connector 251 of the terminal block 25 and the male connector 243 of the power supply device 24. And finally, the operator can arrange the light source unit 24 with a fitting structure (not shown) provided in the instrument body 1 and the mounting member 21, respectively, so that the power supply device 24 is accommodated in the recess 11 of the instrument body 1. 2 is attached to the instrument body 1. The lighting fixture A is constructed on the ceiling according to the above procedure (see FIGS. 4 and 5).

この照明器具Ａでは、端子台２５と電源装置２４の間にプルスイッチ２６の接点２６１を介在させており、引き紐２６２を引いて接点２６１が閉じると電源装置２４への給電が開始され、電源装置２４により生成された直流電力によりＬＥＤ２２２が点灯する。再度引き紐２６２を引いて接点２６１が開くと電源装置２４への給電が停止され、ＬＥＤ２２２が消灯する。つまり、機能部品であるプルスイッチ２６を端子台２５と電源装置２４の間に接続することで、ＬＥＤ２２２の点灯／消灯を切り替えることができる。   In this lighting fixture A, the contact 261 of the pull switch 26 is interposed between the terminal block 25 and the power supply device 24. When the pulling cord 262 is pulled and the contact 261 is closed, the power supply to the power supply device 24 is started, and the power supply The LED 222 is lit by DC power generated by the device 24. When the pull string 262 is pulled again and the contact 261 is opened, the power supply to the power supply device 24 is stopped and the LED 222 is turned off. In other words, the LED 222 can be switched on / off by connecting the pull switch 26, which is a functional component, between the terminal block 25 and the power supply device 24.

本実施形態の照明器具Ａによれば、端子台２５と電源装置２４の間にプルスイッチ２６を接続することで、光源ユニット２への給電を入／切する機能を追加することができ、しかも端子台２５と電源装置２４の間にプルスイッチ２６を接続するだけでいいので、コストアップ及び作業工数の増加を抑えることができる。また、本実施形態の照明器具Ａのように、機能部品であるプルスイッチ２６を器具本体１に取り付けた場合には、器具本体１に取り付けられた端子台２５との間を接続する電線２５２，２５３の長さを短くすることができる。   According to the lighting fixture A of the present embodiment, by connecting the pull switch 26 between the terminal block 25 and the power supply device 24, it is possible to add a function for turning on / off the power supply to the light source unit 2, and Since it is only necessary to connect the pull switch 26 between the terminal block 25 and the power supply device 24, an increase in cost and an increase in work man-hours can be suppressed. Moreover, when the pull switch 26 which is a functional component is attached to the appliance main body 1 like the lighting fixture A of this embodiment, the electric wire 252 connecting between the terminal block 25 attached to the appliance main body 1. The length of 253 can be shortened.

なお本実施形態では、プルスイッチ２６を機能部品としたが、例えば人感センサや明るさセンサなどのセンサ類であってもいいし、非常時に点灯する非常用照明装置や調光信号を出力する調光装置などであってもよい。   In the present embodiment, the pull switch 26 is a functional component. However, for example, sensors such as a human sensor or a brightness sensor may be used, and an emergency lighting device that is turned on in an emergency or a dimming signal is output. A dimmer or the like may be used.

In this case, the female connector 271 connected to the sensor 27 is connected to the male connector 291 of the connection cable 29, and the male connector 243 connected to the power supply device 24 is connected to the female connector 292 of the connection cable 29. The male connector 272 connected to the sensor 27 is connected to the female connector 282 of the connection cable 28, and the female connector 251 connected to the terminal block 25 is connected to the male connector 281 of the connection cable 28.

上述のように接続することで、センサ２７の検出結果に応じて電源装置２４への給電をオン／オフすることができる。また、上述のようにコネクタ同士を接続するだけでいいので、センサ２７（機能部品）の追加又は電源の直結を容易に切り替えることができる。   By connecting as described above, the power supply to the power supply device 24 can be turned on / off according to the detection result of the sensor 27. Moreover, since it is only necessary to connect the connectors as described above, the addition of the sensor 27 (functional component) or the direct connection of the power source can be easily switched.

さらに、本実施形態では、機能部品であるプルスイッチ２６を器具本体１に取り付けているが、光源ユニット２にプルスイッチ２６を取り付けてもよく、本実施形態に限定されない。   Furthermore, in this embodiment, the pull switch 26 which is a functional component is attached to the instrument main body 1, but the pull switch 26 may be attached to the light source unit 2, and is not limited to this embodiment.

また、本実施形態では、端子台２５とプルスイッチ２６の間を電線２５３で接続するとともに、雌型コネクタ２５１とプルスイッチ２６の間を電線２５２で接続したが、例えば端子台２５の雌型コネクタ２５１に接続される雄型コネクタ（第１接続部）と、電源装置２４の雄型コネクタ２４３に接続される雌型コネクタ（第２接続部）をプルスイッチ２６に設け、端子台２５とプルスイッチ２６の間及び電源装置２４とプルスイッチ２６の間をそれぞれコネクタで接続してもよい。   Further, in the present embodiment, the terminal block 25 and the pull switch 26 are connected by the electric wire 253 and the female connector 251 and the pull switch 26 are connected by the electric wire 252, but for example, the female connector of the terminal block 25 is used.
