<p><P>PROBLEM TO BE SOLVED: To reduce consumption power required for standby waiting of a signal. <P>SOLUTION: The lighting control system for remote controlling a lighting device 40 detects a control signal from a remote controller 30 by rectification circuit 11 on which a bias voltage is applied. According to detection of the signal, a switch control circuit 14 carries out opening and closing of a switch 50 of the lighting device 40. An external energy receiving part 23 obtains energy from external environment and converts it into an electric energy. An internal battery 21 is charged by the converted electric energy. A power supply control circuit 22 supplies a drive voltage and the bias voltage of the rectification circuit 11 from the electric energy converted by the energy receiving part 23 or from the electric energy stored in the internal battery 21. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
