The present invention provides a light-emitting diode (LED) dimming drive circuit. The LED dimming drive circuit comprises: a bidirectional triode thyristor (TRIAC) dimmer, used for adjusting an inputted alternating voltage; and a self-excited oscillation pulsed converter (RCC), connected to the TRIAC dimmer, and used for adjusting an alternating voltage from the TRIAC dimmer and providing a drive current for an LED load. |
