摘要
随着社会的发展和人口的增长,人们需要面对环境和资源的严峻挑战,于是新一代的照明灯具——太阳能LED路灯受到了越来越多的关注。本文设计了一具双电源供电模式、具光控和时控功能、具有较强抗干扰能力的功率为40W左右的太阳能LED路灯。文中介绍了路灯LED发光面板的设计、太阳能电池与蓄电池的选择,同时详细讨论分析了路灯各部分驱动电路的工作原理,并对主要电路用Protues和keil软件进行了仿真。仿真结果与理论分析结果相符。
With the social development and population growth, people need to face the severe challenges of environmental and resources. So the next generation lighting-solar-powered LED road lights have been took more and more attention. In this paper, a LED road lights supplied by solar energy with 40W output power is designed and a dual power supply mode is adoped. The LED road light has the functions of light controlling and timing. In this paper, the operation principles of solar-powered LED road lights and solar ceils have been introduced and the selection criterion of solar cell and the designation of LED panel have also been given. Each part of circuits in the solar-powered LED road lights has been discussed in detail. At last, the main parts of the circuits are simulated by Protues and Keil softwares. The simulation results are in line with the theoretical analysis results.
