摘 要
太陽能 LED 路燈系統(tǒng)是一種獨立運行的光伏發(fā)電系統(tǒng),由太陽能電池、蓄電池、LED 路燈、充電電路、放電/驅(qū)動電路、控制器六個部分組成。太陽能 LED 路燈系統(tǒng)在控制器的控制下,白天太陽能電池通過充電電路向蓄電池充電,夜間蓄電池放電驅(qū)動 LED 路燈。如果蓄電池經(jīng)常過放或過充,會造成蓄電池壽命大大縮短,所以控制器的設(shè)計是非常重要的。
本文設(shè)計了一個光伏發(fā)電系統(tǒng)管理控制芯片,實現(xiàn)對太陽能LED路燈的智能控制,設(shè)計出太陽能LED路燈控制系統(tǒng)。

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.
