<p>PROBLEM TO BE SOLVED: To provide an illumination control device to reduce erroneous detections of a human sensor caused by radiation heat or the like from a light source and a cylindrical body and to surely carry out an output control of a illumination-load by human detection. SOLUTION: This illumination device has a sensor fixture 1 removably mounted on a wiring duct D and provided with the human sensor 11 to detect a moving object, and an illumination fixture 2 having the illumination-load 23 and an illumination circuit part 22 to control and light the illumination-load 23, and the sensor fixture 1 transmits information detected by the human sensor 11 as a radio signal from a radio-signal transmitting part 13. If the lighting fixture 2 receives the radio signal from the sensor fixture 1 at the radio-signal receiving part 21, the output of the illumination-load 23 is changed based on the received radio signal.</p> |
