PURPOSE: An apparatus and a method for controlling lighting is provided to control the phase of power by receiving an audio signal through an FM band multi-channel frequency by wireless. CONSTITUTION: An RDS(Radio Data System) FM transceiver(110) receives an audio signal and a data signal transmitted from a sound source generator through an FM band. A PWM(Pulse Width Modulation) power control unit(120) controls the power inputted to a lighting device through a PWM method. A phase detection controller(130) detects the phase origin of the AC power. A controller(140) controls the flash of the general lighting for AC or an LED lighting for DC according to resolution. A PNP type driver(150) supplies power to the LED lighting for DC. A traic driver(160) supplies power to the general lighting for AC. |
