<p>PROBLEM TO BE SOLVED: To securely perform remote control to a luminaire without performing useless transmission of a signal. SOLUTION: A device is composed of a remote control device 2 formed of a human body detection part 2a to detect if a human body exists, an illuminance detection part 2b to detect a peripheral brightness level, a control part to receive detection signals from the human body detection part 2a and the illuminance detection part 2b to output a control signal to light or light off a luminaire 1, a signal transmission part 2d to transmit the control signal from the control part 2c as an optical signal, and a power source part 2k for this, and the luminaire 1 of which turning-on/off is controlled by the optical signal from the signal transmission part 2d of the remote control device 2. In this case, a signal for lighting or lighting off is transmitted from the signal transmission part 2d to the luminaire 1, where a resignal for lighting or lighting off is transmitted from the signal transmission part 2d for at least a specified number of times regardless of a detection signal from the human body detection part 2a in the case where there is almost no change in a detected brightness level by the illuminance detection part 2b between before and after transmission of the signal.</p> |
