LED日光灯驱动电路的设计

摘要

With the rapid development of the LED,white LED light source compares with the traditional light source has long service life,solid state lighting is not easy to damage,high photosynthetic efficiency,mercury-free environmental protection,anti-quake and other advantages.It will become the third generation of light source in future,will bring another revolution in the field of lighting.It is necessary to have LED driver power supply to fit LED lighting.This paper introduces PWM control mode switch design to implement a white LED high power drive circuit.%随着LED的迅速发展.白光LED光源相比的传统光源具有寿命长、固体照明不易损坏、高光效、无汞环保、抗震等优点,未来将成为第三代光源,将带来照明领域的又一次革命.将LED使用到照明领域,需要适合LED的驱动电源,文中利用PWM开关控制方式设计实现了一种白光LED的大功率驱动电路
