摘 要
太阳能 LED 路灯系统是一种独立运行的光伏发电系统,由太阳能电池、蓄电池、LED 路灯、充电电路、放电/驱动电路、控制器六个部分组成。太阳能 LED 路灯系统在控制器的控制下,白天太阳能电池通过充电电路向蓄电池充电,夜间蓄电池放电驱动 LED 路灯。如果蓄电池经常过放或过充,会造成蓄电池寿命大大缩短,所以控制器的设计是非常重要的。
本文设计了一个光伏发电系统管理控制芯片,实现对太阳能LED路灯的智能控制,设计出太阳能LED路灯控制系统。

Abstract
Solar LED lamp system is a stand-alone photovoltaic power system. It is composed of solar battery, storage battery, LED lamp, charging circuit, discharging/driving circuit and controller. The solar LED lamp system is controlled by the controller. The solar battery recharges the storage battery through the charging circuit in the daytime, and the storage battery drives the LED lamp at night. If the storage battery is often over-discharged or overcharged, the battery life will be shortened greatly. Therefore, the controller design is very important.
A chip managing and controlling the photovoltaic power system is designed in this thesis. It achieves intelligent control of the solar LED lamp system so that the solar LED lamp control system is designed.
