<p>PROBLEM TO BE SOLVED: To reduce noise elements affecting to a remote control signal due to a lighting load, enhance the accuracy and reliability of remote control communications, shorten the time required by remote control communications, and thereby form up an easy-to-use system in the lighting system combining a luminaire with remote control. SOLUTION: In the lighting system which is formed of a luminaire D capable of receiving remote control signals, and of changing arbitrarily the lighting condition of itself, and of a remote control receiver and transmitter G capable of changing the lighting condition of the luminaire by remote control signals, before or in the early stage of the time when, communication is started by remote control signals, and at the time when communication is established, the lighting condition of the load for the luminaire (lighting frequency and illuminance) is changed, or the remote control signals (transmitting intensity, communication speed or the frequency of carrying waves) are thereby changed.</p> |
