Patent ID: 8760064

Claim:
An LED lighting apparatus comprising: a rectification block configured to rectify an AC voltage to a DC rectified voltage; an LED block including a first light emitting group and a second light emitting group each including one or more LEDs; a charging/discharging block configured to charge electric charges in a charging period, and discharge electric charges in a discharging period such that the LED block emits light; a driving control unit configured to determine a voltage level of the rectified voltage output from the rectification block, controls a path selection switch to connect the rectification block to the LED block and controls the charging/discharging block to charge the charging/discharging block with electric charges, when the voltage level of the rectified voltage enters the charging period, and controls the path selection switch to connect the rectification block to a ground and controls the charging/discharging block to discharge electric charges from the charging/discharging block to the LED block, when the voltage level of the rectified voltage enters the discharging period; and a path selection switch configured to connect the rectification block to the LED block in the charging period, and connect the rectification block to the ground in the discharging period.
