<p><P>PROBLEM TO BE SOLVED: To provide a lighting control system, in which the wiring work for the control is unnecessary and which is suitable for use in a large place. <P>SOLUTION: The lighting control system comprises a remote control device 1 for transmitting a control signal to control a lighting load as infrared wave, an interface device 2 for converting the control signal received from the remote control device 1 into radio wave and transmitting it, and a plurality of lighting devices 3a-3c, each having the lighting load. The lighting devices 3a-3c have the function of relaying the control signal A1. By transmitting and receiving the control signal using a radio signal, such as infrared wave and radio wave, the wiring work for signal lines for the control signal becomes unnecessary to reduce construction cost. In addition, even to the lighting device 3c where the control signal A1 transmitted by the interface device 2 is not relayed directly, the other lighting device 3b transmits the control signal A1, by relaying the control signal A1, and as a result, the system is suited for use in a large place. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
