Abstract
Provided is a control circuit of a light emitting diode (LED) lighting apparatus which is capable of reducing a flicker while performing a lighting operation using a rectified voltage. The control circuit may include a charge and discharge module charged to perform a charge operation using a rectified voltage and a discharge operation for LED channels, and the charge and discharge module may provide a discharge current to the LED channels during a discharge period including the lowest current point at which the level of the current supplied to the plurality of LED channels is the lowest. Thus, a flicker of the LED lighting apparatus can be reduced.
