Abstract
A light emitting diode dimmer circuit uses a typically commercially available TRIAC dimmer to modulate an illumination-purpose light emitting diode circuit, and to make up the shortfall of the AC voltage phase, caused by the conductivity phase angle of the TRIAC dimmer, for the energy storage applying the energy storage and rectifier circuit, so that the light output of the light emitting diode can achieve the stable and flicker-free effect in the dimming requirement of the light emitting diode either the micro bright or full bright requirement.
