太阳能供电的LED照明系统设计

Design of Solar-Powered LED Lighting System

由于太阳电池和LED的工作电流都是直流,通过太阳电池组件可以通过串并联方式组合得到LED照明系统实际需要的电压。本文将研究太阳能与LED结合的高能源利用率、高安全性能和可靠性的照明系统,重点研究太阳能的充电电路、LED智能照明的控制电路和LED驱动电路。结果证明本文的设计提高了太阳能的利用效率和降低了整个照明系统的能耗,同时有望发展成为借助于并网技术实现蓄电池充放能量的技术方案。

Since both solar cell and LED work with direct current, and different voltages can be obtained by series and parallel solar cell components. This article studies on the lighting system with the combination of solar energy and LED for high energy effi-ciency, high safety performance and reliability. Intelligent charging circuit of solar cells, intelligent lighting circuit and driving cir-cuit of LED are specially investigated. This design has been proved to improve the efficiency of the entire lighting system, and is ex-pected to be developed into a battery charge and discharge energy technology programs based on network technology.
