现有的太阳能LED光伏控制器成型产品有很多，且各有特点，但续航能力均有不足，在江南等连续阴雨天多的情况下可能会出现能源不济的情况，针对这种情况，本文提出了一种设计方案，使用PWM驱动MOSFET控制输出电流的大小，并采用独立电源的定时器件满足全时段定时定功率的输出需求，从而可以做到在光照要求较低的情况下降低路灯的光照度，以延长照明时间。

The present photovoltaic solar LED current controllers are various in molding products, but different in properties and inadequate in battery life which occurs especially in the consecutive rainy days in the south. To solve the problem, the paper proposes a design scheme in which PWM drive is used for MOSFET to control the output current and timing device with independent power supply adopted to meet the regularly scheduled full - time power output requirements so as to reduce the illumination of street lamps to extend the lighting time in the ease of low lighting requirements.
