摘　　要：太阳能是一种绿色能源,在照明领域的应用日益广泛,已具有太阳能草坪灯、庭院灯、台灯及城市光彩工程灯等许多品种。本文介绍的照明电路可分成四部分,其中三部分采用运算放大器构建三组电压比较器,分别达到光控、过充保护和欠压保护的目的。在光控电路中,利用太阳能光伏电池本身作为光敏元件,可简化电路。因此,该电路具有蓄电池过充保护和欠压保护、光控开关灯及定时照明等功能。Solar energy is a kind of green power, which has a wide application foreground in lighting field. There are many kinds of products, such as lawn lantern, courtyard-light, reading lamp and decorative lamp of city. The lighting circuit presented in this paper is divided into four parts. Three parts use operation amplifiers to construct three voltage comparators , and can achieve aim to optical control , time control , overcharge protection and under-voltage protection respectively. In optically controlled circuit, solar energy photovoltaic batteries are used as photo detectors, which can simplify the circuit. Therefore, this circuit has good function of overcharge protection and under-voltage protection for storage battery, optical controlled switch, timing control illumination.
