Abstract
A driving device for driving a light source module () includes an inverter circuit (), a signal sensing circuit (), a microcontroller (), and a control circuit (). The inverter circuit converts a received power signal to an alternating current (AC) signal. The signal sensing circuit is connected to the inverter circuit and the light source module, and generating protection signals of the driving device. The microcontroller receives the protection signals output from the signal sensing circuit, and outputs a logic control signal. The control circuit receives the logic control signal and controls the AC signal output from the inverter circuit according to the logic control signal.
