Title:
LED LIGHTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/183893
Kind Code:
A1
Abstract:
An objective of the present invention is to provide a circuit that prevents the operating current of a triode for alternating current (TRIAC) dimmer from dropping below a holding current value. To this end, an LED lighting device includes an LED terminal, a load terminal, a bridge rectifier circuit terminal, and a TRIAC dimmer, wherein the TRIAC dimmer adjusts the intensity of light of the LED terminal; the load terminal is connected between the output terminal of the TRIAC dimmer and the bridge rectifier circuit terminal and stabilizes the operation of the TRIAC dimmer even in the low dimming adjusting section of the TRIAC dimmer; the bridge rectifier circuit terminal is connected to the load terminal and supplies power to the LED terminal; and the LED terminal receives actuating power from the bridge rectifier circuit terminal.
