<P>PROBLEM TO BE SOLVED: To control lighting of a plurality of LED lamps only by preparing a comparatively simple circuit in an illumination system using the plurality of LED lamps and controlling the plurality of LED lamps by a radio switch. <P>SOLUTION: The illumination system includes: a power supply control device 12 capable of controlling the illuminance of respective lighting apparatuses 11 by outputting a current for driving the lighting apparatuses 11 and controlling the current; the plurality of lighting apparatuses 11 to be turned on by the power supply control device 12; and a switch device including an automatic energy supply device for converting operation force of a switch button into electric energy. The power supply control device 12 is compose of: a first circuit part including a receiver 24 capable of receiving radio signals of predetermined frequencies and control signal generation circuits 25, 26 for generating a control signal corresponding to the number of times of reception of the radio signals and allowed to be driven by a first power supply system; and second circuit parts 21, 22 which are driven by a second power supply system and capable of outputting a current corresponding to the control signal outputted from the first circuit part. In the illumination system, when a current is not outputted, the second power supply is not operated. <P>COPYRIGHT: (C)2012,JPO&INPIT |
