摘要： A driving device for driving a light source module (34) includes a power stage circuit (31), a transformer and resonance circuit (32), a current balancing circuit (33), a voltage sensing circuit (35) and a PWM controller (37). The power stage circuit converts a received direct current (DC) signal to an alternating current (AC) signal. The transformer and resonance circuit converts the AC signal to an appropriate signal to drive the light source module. The current balancing circuit is connected between the transformer and resonance circuit and the light source module, for balancing current flowing through the light source module. The voltage sensing circuit is connected to the transformer and resonance circuit, for sensing a voltage level of the appropriate signal provided to the light source module. The PWM controller is connected between the voltage sensing circuit and the power stage circuit, for controlling output thereof according to the sensed voltage level.
