Research of a New Type of Power Driver of LED Lamp

In view of problems of multi-fault and short service life existed in LED street lamp lighting,a new type of LED power driver of LED lamp was designed.The driver uses digital control technology of MCU single-chip microcomputer to achieve power output current,voltage intelligent and controllable,meanwhile choking coil,magnetic amplifier were used to filter ripple wave and completely remove electrolytic capacitor,so as to improve product reliability,greatly extend the life of the LED lamp.
