由于太阳能光源是21世纪最具发展前景的光电科技,随着科技的不断发展,光伏电源技术被广泛利用。让污染远离地球,把绿色带回家园,将太阳赏给大地的光明在白天储存,夜晚为人类照明,使越来越多的太阳能路灯成为公共露天场所理想的照明首选。本文针对太阳能路灯的工作方式,设计的控制电路可以实现太阳能电池组件向蓄电池组充电,晚上由蓄电池组提供电能给LED灯光源供电,实现照明。本电路具有过充、过放保护功能,确保蓄电池组不因过充或过放而被损坏。同时设计了光控时控、市电自动接入充电、照明等功能,避免了连续阴天不能充电和照明的情况。
As the solar light source is the 21 st century the most promising optoelectronic technology, with the continuous development of science and technology, photovoltaic power technology is widely used. Keeping pollution away from the earth, bringing green back home, storing the sun’s light to the earth’s light during the day, nighttime lighting for humans, make more and more solar street lights the ideal lighting choice for public open spaces. In this paper, the working way of solar streetlamp, the design of the control circuit can achieve the solar battery module to charge the battery pack, night by the battery pack to provide power to the LED lamp light source to achieve lighting. This circuit has overcharge, over discharge protection, to ensure that the battery is not overcharged or over-discharge is damaged. At the same time the design of the light-controlled time control, mains charging access, lighting and other functions, to avoid the continuous cloudy can not be charged and lighting conditions.
