THE APPARATUS AND METHOD OF ELECTRIC POWER CONTROL BY AUDIO SIGNAL

摘要

PURPOSE: A power control device and a method thereof are provided to control a phase of a power by wirelessly receiving an audio signal through an ISM(Industrial Scientific Medical) band multichannel frequency. CONSTITUTION: A power control device includes an audio signal generating module(100) and a lighting control module. The audio signal generating module includes an RF transmitting module(130) and a divider(120). The divider divides an audio signal into 256 hex values. The RF transmitting module is arranged inside a lighting fixture. The RF transmitting module transmits the audio signal to the lighting control module through an ISM band multichannel frequency. The lighting control module automatically turns on/off the lighting fixture by controlling a phase of an AC power according to the audio signal received from the audio signal generating module.
