太阳能LED路灯照明系统优化设计

The Optimal Design of Solar LED Street Lamp lighting System

在珠海完成国内第一个太阳能LED路灯示范工程的工作基础上,从路灯光源、控制电路、太阳电池组件最佳倾角确定、太阳电池组件和蓄电池容量确定等几个方面对太阳能路灯进行了设计优化,做到既能保证系统的稳定可靠运行,又能尽量减少系统规模和降低成本。结果表明采用LED作为路灯光源、直接耦合的方式的充放电控制器是太阳能路灯很好的选择,同时通过科学计算的方法对在珠海地区使用时太阳电池组件最佳倾角和组件和蓄电池容量进行了讨论。使用的方法和结论可以为的其他的太阳能路灯设计提供有力的帮助。

On the basic of completing the Chinese first solar LED street lamps project at Zhuhai, to purpsue reliability and economy of solar steet lamp systems, the systems were optimally designned from four aspects： light source, charging controller circuit, optimum tilt angle of photovoltaic module, sizing of photovoltaic module and storage battery. As a result, the LED light source and direct - coupling charging controller are very good choices for solar street lamp systems, at the same time, by the method of scientific calculation, the optimum tilt angle of photovoltaic module, sizing of photovoltaic module and storage battery were discussed, too. At the last, the method and conclusion in this paper can also be used to help the design of other solar street lamp syetems.
