ABSTRACT:
A driving device for driving a light source module (32) includes a switch circuit (30), a transformer circuit (31), a voltage sensing circuit (34), a current sensing circuit (35), and a PWM controller (33). The switch circuit converts a received direct current (DC) power signal to an alternating current (AC) signal. The transformer circuit converts the AC signal to an appropriate signal to drive the light source module. The voltage sensing circuit receives the DC power signal and senses a voltage level of the DC power signal. The current sensing circuit receives the DC power signal and senses a current level of the DC power signal. The PWM controller controls the AC signal output from the switch circuit according to the sensed voltage and current levels.
