Send to. Then, the lighting circuit unit 22 changes the output of the lighting load 23 based on the detection signal from the radio signal reception unit 21.

As an example of lighting control of the lighting load 23 by the lighting circuit section 22, for example, when the lighting load 23 is turned on / off based on a detection signal from the radio wave signal receiving section 21, or when the detection signal is received. After the specified holding time, the lighting is maintained at full lighting for a predetermined holding time.
May be turned off. At this time, if the detection signal is received again during the predetermined holding time, the count of the predetermined holding time is cleared and the time counting is performed again.
The full lighting may be maintained.

Here, in the present embodiment, the radio wave signal has a form which is predetermined between the sensor fixture 1 and the lighting fixture 2, and the radio wave signal is out of the form, for example, a modulation method or a modulation frequency. Different radio wave signals are set not to be received by the radio wave signal receiver 21.
