LED A Device for Driving a LED using a Dimmer for Fluorescent Lamps

摘要

The present invention relates to an LED lighting device using a dimmer and, more specifically, to an LED lighting device using a dimmer, an alternating-current dimmer which adjusts the brightness of an incandescent lamp using AC power or a fluorescent lamp using AC power, to adjust the brightness of an LED lighting using and DC power. The LED lighting device comprises: a dimmer which converts input AC power to output AC power in accordance with a phase control scheme; an LED drive control signal generating part which analyzes the output AC power and generates an LED drive control signal in accordance with an analysis resu an LED drive part which receives the output AC power and the LED drive control signal, and converts the output AC power into an LED power in accordance with the LED drive control signal; and an LED part which emits light when the LED power is supplied.
