Abstract:
Provided is a circuit for preventing an operating current of a TRIAC dimmer from being dropped below a holding current value. In this regard, a light emitting diode (LED) lighting device includes a TRIAC dimmer for controlling intensity of light emitted from an LED, a load connected between an output terminal of the TRIAC dimmer and a bridge rectifier to stabilize operation of the TRIAC dimmer even in low dimming level periods of the TRIAC dimmer, the bridge rectifier connected with the load to supply an operating current to the LED; and the LED for receiving the operating current from the bridge rectifier.
