Patent ID: 7863826

Claim:
An illumination control apparatus using a pulsating wave, comprising: a power generator 10 which filters externally supplied power and supplies to a power control voltage generator; a power control voltage generator 20 which includes a rectifier 21 for rectifying the voltage from the power generator, a constant voltage generator 22 for generating a constant voltage from the rectifier, a fan motor controller 24 for controlling a fan motor in accordance with a driving signal from the CPU controller 40 and a pulsating wave generator 23 for generating a pulsating wave; a power controller 30 which controls a level width of a pulsating voltage from the pulsating wave generator 23 by using a switching device; a CPU controller 40 which supplies a driving signal to the fan motor controller 24 and the power controller 30 ; and a power output unit 50 which filters noises of pulsating wave voltages from the power controller 30 and outputs the same.
