摘　　要：鉴于目前对太阳能新型能源的研究及相关技术的发展,设计了一种新型的太阳能LED照明系统。该系统以ATMEGA16单片机为控制核心,实现对蓄电池能量的智能管理和系统工作状态的准确控制。蓄电池和市电自动切换提供照明系统的电源。蓄电池充电状态的准确性由电压电流检测双环及核心控制器保证,并将最大功率跟踪算法运用其中,以实现精确的控制。LED亮度根据实际太阳光强度由控制器及TPS61042准确控制。多次测试实验结果表明该系统控制准确,转换效率较高,工作稳定。Considering the development of solar energy, the paper designs a new solar cell LED lighting system. It takes a cheap ATMGA16 as the intelligent controller. The proposed energy management controller effectively enhances the system performance. The controller uses the maximum power point tracking （MMPT） scheme to precisely control the battery charge. Automatic switching between battery and utility provides power supply of the lighting system. According to the actual intensity of the sun, the controller and TPS61042 accurately control the LED brightness. The experimental results show that the system controls accurately, conversion efficiency is high, and it works stably.
