Circuit for driving AC direct lighting apparatus and method therefor
Disclosed is a circuit for driving an AC direct lighting apparatus, including a triac dimmer configured to control a brightness of an LED module, a charger configured to be charged during a turn-off period of the triac dimmer, a reference voltage generator configured to generate a reference voltage based on a voltage charged in the charger during a first turn-off period of the triac dimmer and a voltage charged in the charger during a second turn-off period, and a driving signal output unit configured to output a driving signal of the LED module in response to a voltage charged in a third turn-off period of the triac dimmer reaching the generated reference voltage. Accordingly, the driving circuit manages a driving time deviation of the LED module, removing a flicker phenomenon from the light produced by the module.
