Abstract: The present invention discloses a power control circuit for adjusting light, which adopts both frequency modulation and amplitude modulation for the control and starts using the amplitude modulation control after the frequency change exceeds a predetermined limit range, such that the voltage and frequency for driving the lamp set fall within a range acceptable to the lamp set and minimize the effect of frequency interferences.
