DRIVING CIRCUIT FOR LIGHT EMITTING DIODE

摘要

Disclosed is an AC direct-type LED driving circuit. The LED driving circuit of the present invention relates to an AC direct-type LED driving circuit for driving an LED array to be connected to LEDs. The AC direct-type LED driving circuit includes a control unit which includes at least two switches connected to the LED array and an LED driving current control circuit for selectively opening/closing the switches, and a switchable fill circuit which includes a capacitor, receives the rectification voltage of an AC voltage, charges the capacitor, and supplies a charge current from the charged capacitor to the LED array.
