一种无级调光隔离反激 LED 开关电源的设计

摘要

随着 LED 技术的高速发展,LED 照明产品得到广泛的应用。LED 与传统光源相比更易于进行调光控制。文中以常见的小功率隔离反激 LED 开关电源为平台,重点介绍了一种无级调光功能的实现方式,使得 LED 灯具更能充分发挥其易于控制的优势,以适应更多的应用场合。%With the rapid development of LED technology,LED lighting products are used more and more widely.As we know,LED is much easier for dimming comparing to traditonal lighting source.Based on isolation flyback LED switc-hing mode power supply platform,this paper introduces a realization method of stepless dimming,making the LED light fixture give full play to the advantages of easy control,to match more applications.
