Abstract

A digital control circuit of a lighting module is for driving a power transforming circuit and a light source driving circuit. The digital control circuit includes a power control loop, a light source control loop and a main control loop. The power control loop generates a digital power control signal. The light source control loop generates a digital light source control signal. The main control loop outputs the digital power control signal to drive the power transforming circuit, and outputs the digital light source control signal to drive the light source driving circuit.
