Abstract
Disclosed is a lighting apparatus which includes LEDs and reduces flicker. The lighting apparatus may secure a charge voltage by performing a charge operation using a current corresponding to a rectified voltage equal to or more than a preset level, and compensate for the rectified voltage provided to a lighting unit including LED groups by performing a discharge operation for the charge voltage in response to the rectified voltage less than the preset level, thereby reducing flicker.
