Method for Controlling LED Lightings

摘要

PURPOSE: An LED control method is provided to reduce the volume and weight of a power device by applying a single stage power converter to simplify the configuration of a main circuit. CONSTITUTION: An EMI filter(120) reduces EMI(Electromagnetic Interference). A diode rectifier is composed of a bridge circuit. A single stage power converter is composed of a flyback converter(150). An RDC snubber reduces surge voltages on both ends of a MOSFET. A primary sub power source supplies power to a first control circuit unit(191).
