As shown in FIG. 2, in the lighting fixture 11, the portions other than the lighted portion of the light source 12 are arranged above the indoor ceiling ST in the room R in the vertical direction (ceiling back), and the antenna 15 a configuring the wireless unit 15 is provided in the indoor ceiling ST. It is arranged on the upper side.

また、このアンテナ１５ａは、図４（ａ）（ｂ）に示すように照明器具１１の金属製の筐体１１ａ内に備えられる。ここで、筐体１１ａには無数の貫通孔１１ｂが形成され、前記アンテナ１５ａは前記貫通孔１１ｂのいずれかから視認可能な位置に設けられている。このため、アンテナ１５ａ側への無線通信用（受信用）の信号が前記筐体１１ａによって遮蔽されるといったことが抑えられている。なお、前記貫通孔１１ｂは様々な規格に沿って予め形成した照明器具１１を壁や天井ＳＴに取り付けるための孔の内で余った孔であることが好ましい。   In addition, the antenna 15a is provided in a metal casing 11a of the lighting fixture 11 as shown in FIGS. Here, a myriad of through holes 11b are formed in the housing 11a, and the antenna 15a is provided at a position that can be seen from any of the through holes 11b. For this reason, it is suppressed that the signal for radio | wireless communication (for reception) to the antenna 15a side is shielded by the said housing | casing 11a. In addition, it is preferable that the said through-hole 11b is a surplus hole in the hole for attaching the lighting fixture 11 previously formed along various standards to a wall or the ceiling ST.

図３（ｂ）に示すように、センサ部２１は、室内Ｒ内の人の有無を検知するセンサ本体２２を備え、このセンサ本体２２を制御する制御部２３と電気的に接続される。また、制御部２３は、前記センサ本体２２からの検知信号を前記照明器具１１の無線部１５に送信する送信用の無線部２４と電気的に接続され、前記検知信号を前記無線部２４を介して照明器具１１側に出力するようになっている。また、センサ部２１は、図２に示すようにセンサ本体２２の検出面以外が室内Ｒの天井ＳＴよりも鉛直方向上側（天井裏）に配置され、無線部２４を構成するアンテナ２４ａが天井ＳＴよりも上側に配置されるようになっている。   As shown in FIG. 3B, the sensor unit 21 includes a sensor main body 22 that detects the presence or absence of a person in the room R, and is electrically connected to a control unit 23 that controls the sensor main body 22. The control unit 23 is electrically connected to a transmission wireless unit 24 that transmits a detection signal from the sensor main body 22 to the wireless unit 15 of the lighting fixture 11, and the detection signal is transmitted via the wireless unit 24. Output to the lighting fixture 11 side. Further, as shown in FIG. 2, the sensor unit 21 is arranged on the upper side in the vertical direction (back of the ceiling) of the room R except for the detection surface of the sensor main body 22, and the antenna 24 a configuring the radio unit 24 has a ceiling ST.

The operation unit 32 is electrically connected to the control unit 33, and the control unit 33 transmits a signal to the radio unit 34 according to an operation button of the operation unit 32 and transmits the signal to the radio unit 15 of the lighting apparatus 11. 34.

次に、本実施形態の照明システムの動作例（作用）について説明する。
室内Ｒに人がドア等を開けて入った場合、センサ本体２２はその旨を検知して制御部２３に対して検知信号が出力する。制御部２３は、検知信号が入力されるとその信号を無線部２４のアンテナ２４ａから送信する。アンテナ２４ａからの検知信号は照明器具１１側の無線部１５のアンテナ１５ａで受信され、受信した検知信号に基づいて照明器具１１の制御部１４は点灯回路１３を介して光源１２を非点灯状態から点灯状態に切り替える。 Next, an operation example (action) of the illumination system of this embodiment will be described.
When a person enters the room R by opening a door or the like, the sensor main body 22 detects that fact and outputs a detection signal to the control unit 23. When the detection signal is input, the control unit 23 transmits the signal from the antenna 24 a of the wireless unit 24. The detection signal from the antenna 24a is received by the antenna 15a of the radio unit 15 on the lighting fixture 11 side, and the control unit 14 of the lighting fixture 11 switches the light source 12 from the non-lighting state via the lighting circuit 13 based on the received detection signal. Switch to the lighting state.

一方、室内Ｒから人が外にでた場合、センサ本体２２はその旨を前記検知信号の出力を停止させる。制御部２３では、例えば前記検知信号が入力されない時間が所定時間無かった場合、前記アンテナ２４ａからの信号の送信を停止させるようになっている。すると、受信側のアンテナ１５ａによる検知信号の受信ができないため、照明器具１１側ではアンテナ１５ａによって検知信号が所定時間受信できない場合、制御部１４は点灯回路１３を介して光源１２を非点灯状態に切り替える。   On the other hand, when a person goes out of the room R, the sensor main body 22 stops outputting the detection signal to that effect. In the control unit 23, for example, when there is no time for which the detection signal is not input for a predetermined time, transmission of the signal from the antenna 24a is stopped. Then, since the detection signal cannot be received by the antenna 15a on the receiving side, and when the detection signal cannot be received by the antenna 15a on the lighting fixture 11 side for a predetermined time, the control unit 14 puts the light source 12 into the non-lighting state via the lighting circuit 13. Switch.

また、操作器３１の操作部３２が操作されると、制御部３３は、無線部３４からその操作内容に応じた信号を送信する。無線部３４からの信号は照明器具１１側の無線部１５のアンテナ１５ａで受信され、受信した信号に基づいて照明器具１１の制御部１４は点灯回路１３を介して光源１２を非点灯状態と点灯状態とを切り替える。   When the operation unit 32 of the operation device 31 is operated, the control unit 33 transmits a signal corresponding to the operation content from the wireless unit 34. A signal from the wireless unit 34 is received by the antenna 15a of the wireless unit 15 on the lighting device 11 side, and the control unit 14 of the lighting device 11 turns on and off the light source 12 via the lighting circuit 13 based on the received signal. Switch between states.

An excessive burden on the control unit 14 can be suppressed.

（３）アンテナ１５ａが設置される貫通孔１１ｂは様々な規格に沿って予め形成した照明器具１１を壁や天井ＳＴに取り付けるための孔の内で余った孔であるため、別途貫通孔を形成する必要がない。   (3) The through hole 11b in which the antenna 15a is installed is a surplus hole in the hole for attaching the lighting fixture 11 formed in advance according to various standards to the wall or the ceiling ST, so a separate through hole is formed.
