摘　　要：以太阳能电池、动力锂离子电池、大功率白光LED组为主要器件,采用MPPT,锂电池充放电管理,Buck-Boost变换,Boost变换,LED恒流驱动等控制技术,设计了一种太阳能照明控制系统。试验结果表明:该系统充电时基本实现了太阳能电池的最大功率跟踪,因而提高了太阳能电池的效率;系统的LED电流稳定,控制精度可达±1%,延长了LED使用寿命。这表明:新型器件与合理的控制技术的结合将进一步提升太阳能照明系统节能环保的优势。A solar lighting control system is designed in this paper, which is mainly comprised of Solar batteries, hydronium batteries and high power-white light LED pack and it adopts technologies such as Buck-Boost and boost transform, hydronium battery charge and discharge management, LED constant current drive and MPPT. The experiment results showed that the solar battery efficiency can be increased because the solar battery high power-tracking can be basically achieved when the system is charging, the system LED＇ s stable current with ± 1% controlling precision can prolong LED＇ s life. So we can get a conclusion that the combination of new instruments and proper control technology will enhance the advantage of solar lighting system in environment friendly.
