摘要： A light source driving circuit for driving a light-emitting element is provided. The light source driving circuit includes a power supply circuit, a dimming circuit, and a feedback circuit/control circuit. The power supply circuit is connected to a terminal of the light-emitting element, and the dimming circuit is connected to the other terminal of the light-emitting element. The feedback circuit/control circuit is connected between the power supply circuit and the dimming circuit. The light source driving circuit uses the feedback circuit/control circuit to delay the dimming circuit to turn off as the light source driving circuit turned off the power supply to stop outputting a voltage to the light-emitted component. Therefore, the light source driving circuit can prevent the breakdown of the dimming circuit caused by over high voltage.
