Abstract

本发明公开了一种交流高压多段分区驱动光源装置及其方法，该装置包括电源、信号控制模块、n段恒流驱动模块、n个mos管和n段LED灯，其中n为等于或大于2的自然数；信号控制模块上设有一个输入端和n个输出端，电源分别与信号控制模块的输入端和n段LED灯电连接，各段恒流驱动模块与各个mos管一一对应串联，第一段至第m段的LED灯串联后与第m个mos管电连接，其中m为小于或等于n的自然数。本发明根据导通区的功率及兼顾LED光源分布的需要，将LED光源分成多段工作，有效实现了分段越多光效越高的效果，且实现了导通区最大化，无光耗区最小化的效果，提高了电源效率，延长了LED灯的使用寿命，提高了电厂的供电效率。
