The optical wireless unit 90 acts as a repeater between devices installed in the same room. Information is transmitted / received to / from a device installed outdoors by means of the communication device 36. By using a plurality of the optical wireless units 90, it can be used as a data transmission repeater (repeater) from an information outlet on a wall surface.

Next, the operation of the embodiment configured as described above will be described. As shown in FIG. 1A, when the communication function module 10 is attached to the hooking embedded rosette 102 provided on the ceiling 100, each device and each device are connected by the contact point SP as shown in FIG. Then, first, electric power is supplied from the AC power supply 110 to the power supply circuit 80, and further, necessary power is supplied from the power supply circuit 80 to the surveillance camera 20, the optical sensor 30, the radio relay 40, .... This enables each device to operate. For example, the surveillance camera 2
0 indicates that the indoor imaging is started, and the optical sensor 30 starts the infrared detecting operation. The same applies to other devices. Further, the ceiling light 104 is attached to the attachment rosette 14 of the communication function module 10. As a result, power for driving is supplied from the AC power supply 110 to the ceiling light 104, and the LED lights up when a switch (not shown) is turned on.

As described above, according to this embodiment, (1) the hooking embedded rosette 10 provided on the ceiling 100.
Only by providing the communication function module 10 between the 2 and the ceiling light 104, various functional devices operate, and various functions can be enjoyed without impairing the atmosphere in the room.

FIG. 3 shows the entire state of the second embodiment, and FIG. 4 shows the connection of each part. As shown in these drawings, in the present embodiment, the communication function module 200 and the ceiling light 202 are integrated, and the whole of them is attached to the hooking embedded rosette 102 of the ceiling 100. Communication function module 20
0 is almost the same as in the above-described first embodiment, and the surveillance camera 20, the optical sensor 30, the radio wave repeater 40, the microphone 50, the speaker 60, the micro projector 70, and the optical wireless unit 90 are attached respectively. The arm 16 is not provided. A lighting circuit (inverter circuit) 204 of the ceiling light 202 is connected to the AC power supply 110 instead of the mounting rosette 14.

By the way, in this embodiment, since the optical wireless unit 90 and the ceiling light 202 are integrated, the illumination light output from the ceiling light 202 is different from the signal light used in the optical wireless unit 90. May become an interfering light. Therefore, in this embodiment,
The illumination light is set so as not to affect the signal light. Specifically, (1) the inverter frequency of the lighting circuit 204 is set to a value that does not affect the signal light, (2)
The signal waveform applied to the fluorescent lamp (not shown) by the lighting circuit 204 is not a rectangular wave but a sine wave, so that the degree of interference is reduced. (3) The inverter frequency of the lighting circuit 204 is set to the optical wireless unit. By using a notch filter on the 90 side of the equipment, the influence of interference light is reduced, (4)
For example, an optical separating unit that prevents the illumination light from entering the optical wireless unit 90 is used.

On the other hand, it is possible to positively utilize the illumination light of the ceiling light 202. That is, since the communication function module 200 and the ceiling light 202 are integrated, it may be considered that the communication function module 200 exists in the direction of the illumination light output from the ceiling light 202. Therefore, for example, when there is a communication slave unit 210, the illumination light is used as a search pilot signal for directing the direction of the antenna 212 of the communication slave unit 210 toward the communication function module 200. By orienting the antenna 212 in the direction of receiving the illumination light, the antenna 212 can be eventually orientated in the direction of the communication function module 200.

(1) The device for exchanging information, which is mounted on the communication function module, is not limited to the above embodiment, and various devices may be mounted. The same applies to the lighting device, and may be applied to various lighting devices. (2) The case where the invention is applied to the indoor lighting device is a preferable example, but the application to the outdoor lighting device is not hindered. (3) In the above embodiment, all the signal wirings of the communication function module are independently drawn into the ceiling via the rosette. However, as shown in FIG. 5, if the communication protocol conversion circuit 300 corresponding to each signal is provided, it is possible to consolidate the wiring to the under ceiling. Further, if the communication protocol conversion circuit 300 uses a power line such as Echonet as a signal transmission protocol, the communication protocol conversion circuit 30
It is only necessary to connect the output side of 0 to a power outlet (see the dotted line in FIG. 5). For example, in the embodiment of FIG.
It is only necessary to attach the ceiling light 202 to the hanging recessed rosette 102 of the ceiling 100, and the attachment work can be simplified.
