Abstract
A light emitting diode (LED) driving circuit includes a flicker elimination unit configured to perform a flicker removal for LED modules and a driving control unit configured to pause a procedure of the flicker removal based on an AC input voltage that is regulated through a Triode for Alternating Current (TRIAC) dimmer, so as to cause a brightness of the LED modules to be dimmed. Therefore, the LED driving circuit selectively adjusts an LED brightness level and removes LED flicker by using a TRIAC dimmer and controls the brightness level of the LED module based on a dimming level.
