摘要
针对现有LED路灯照明存在故障多,使用寿命短的问题,设计了一种新型LED电源驱动器。该驱动器使用MCU单片机数字控制,实现电源输出电流、电压智能性与可控性,同时采用扼流圈、磁放大器原件等器件进行电源纹波滤波,完全去掉电解电容器,达到提高产品的可靠性,大幅度延长LED路灯使用寿命的目的。
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 micro-computer 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.
