摘要
太阳能是最环保的能源,利用太阳能来照明将是低碳生活的发展趋势。地球资源的日益贫乏,基础能源的投资成本日益攀高,各种安全和污染隐患可谓无处不在,太阳能作为一种“取之不尽、用之不竭”的安全、环保新能源越来越受重视。
太阳能路灯利用太阳电池的光生伏特效应原理,白天太阳电池吸收太阳能光子能量产生电能,通过控制器储存在蓄电池里,当夜幕降临或灯具周围光照度较低时,蓄电池通过控制器向光源供电。太阳能路灯有着节能环保、可靠耐用、安装灵活方便、安全、自主供电等功能。太阳能路灯系统,主要由太阳能光电池组件、蓄电池、控制器和照明灯具组成。在路灯系统的控制下,白天有阳光就充电储能,晚上光控和时空点亮发光负载,照明道路。太阳能路灯系统的控制器是整个路灯系统中充当管理者的关键部件,它的最大功能是对蓄电池进行全面的管理,防反充电控制,防过充电控制,防过放电控制。
本次设计由直流电源稳压电路,单片机控制电路,蓄电池过充过放控制电路,光控检测电路,时间定时电路和市电转换电路组成

Abstract
Solar energy is the most environmental protection energy, using solar energy to lighting will be the development trend of low carbon life. The earth's resources, the increasingly poor based energy investment cost of safety and pollution increasingly up, it is ubiquitous, hidden solar energy as the one kind of "mine, an inexhaustible" new energy safety and environmental protection are ing more and more attention.
Solar street lamps use the sun battery light born volts effect principle, the daytime solar cell absorbs solar photon energy to produce electricity, through the controller in stored in the battery, when night falls or lamps and lanterns at low light around by the controller, battery power to light. Solar street lamps with energy conservation and environmental protection, reliable and durable, installation is flexible and convenient, safety, independent power supply, and other functions. Solar street lamps system, and the main test kit, batteries, solar controller and lighting lamps and position. The streetlights system under the control of daytime have sunlight charge storage, evening light-activated and space-time light shine load, lighting road. Solar street lamps system controller is the whole street lamp system as the ponents, managers of its biggest function prehensive management, battery charge control, prevent counter-attack charging control, prevent after discharge control.
This design by dc power voltage circuit, SCM control circuit, battery overcharge had put control circuit
