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