Patent abstract
A light emitting diode driving apparatus includes a rectifier, a converter, a feedback circuit, and a controller. The rectifier converts alternating current power to direct current (DC) power. The converter supplies driving power to a plurality of LEDs based on the DC power. The feedback circuit generates a feedback signal based on a current flowing in the plurality of LEDs and adjusts a magnitude of the feedback signal. The controller changes a maximum value of a current output by the converter based on the adjusted magnitude of the feedback signal.
