| Abstract | (57) ABSTRACT A driving circuit of light emitting diodes (LEDs) and a light ing apparatus using the same are provided in the application. The driving circuit includes a rectifier unit, an isolation ele ment, a processing unit and a Voltage converter circuit. The rectifier unit is coupled to a triac dimmer and outputs a first operation Voltage. The processing unit detects a conducting condition of the triac dimmer according to a Voltage wave form of the first operation Voltage and outputs a pulse width modulation signal to drive the LEDs according to the detected conduction condition, so that flash problems of the LEDs caused by operation Voltage variation are prevented. |
