Simultaneously with the electrical connection, the power supply locking piece 32 is sandwiched between the second power supply protruding piece 63 and the ceiling plate 6a and locked to the second power supply protruding piece 63. The stop piece 42 is sandwiched between the second signal protruding piece 73 and the ceiling plate 6a, is locked to the second signal protruding piece 73, is mechanically connected, and is attached to the building. That is, the attachment work for attaching the appliance body 1 to the building and the wiring work for electrically connecting the power terminal 3 and the signal terminal 4 to the power line 6b and the signal line 7a, respectively, are simultaneously performed.
[0026]
The operation of this will be described. The detection sensor 5 detects infrared rays emitted from the human body and outputs an infrared detection signal to a control unit (not shown) installed indoors via the signal terminal 4. Then, the control unit grasps the indoor / outgoing state of an indoor person and centrally manages the entrance / exit, outputs a control signal for controlling the semiconductor light source 2 to the signal terminal 4, that is, the signal terminal 4 receives the control signal, Based on the control signal, the semiconductor light source 2 is controlled such as dimming or blinking the emitted light.

[0037]
Moreover, although the detection sensor 5 which detects infrared rays was provided in the instrument main body 1, the detection sensor which detects surrounding illumination intensity is provided, and the emitted light emitted from the semiconductor light source 2 blinks automatically based on the illumination intensity detection signal. Or you may control dimming etc., It is not limited.
[0038]
A second embodiment of the present invention will be described below with reference to FIGS.
