摘　　要：太阳能路灯近年在道路照明,交通发光指示标志等领域广泛使用,太阳能路灯节能环保,施工方便。即免除了架设市政用电的麻烦,还降低了用电成本。大部分路灯的实际使用照明时间在2-8小时之间,可提供的持续照明时间除了取决于蓄电池的容量外还取决于不同光照条件下的充电效率,所以夜间的工作时间也在发生变化。本系统通过对太阳能电池板的方向控制,让太阳能电池板能够随着光线强弱的变化转动,无论阴天还是晴天都能保持一个最佳的充电效率,以获得最好的充电效果,延长夜间照明的时间。系统运用一个AVR单片机为主控制芯片,使用多个光敏传感器组成整列,传感器阵列获取光线强度数据后,单片机进行采样判断,然后控制随动系统调整太阳能板的位置,让太阳能电池板时刻保持正对光线最强的地方,获得更好的充电效率,收集更多电能,让路灯在夜间工作时间更长。与传统路灯相比,引入单片机控制的智能路灯,提供了优异的智能性、可扩展性,为太阳能路灯提供了一种性能更佳,价格更为低廉的解决方案。In recent years, solar street lighting in the road, the traffic signs light is widely used in areas such as solar energy saving lamp, convenient construction. That exempts for the erection of municipal electricity trouble, but also reduces the electricity costs. Most of the time the actual use of street lighting in between 2- 8hours, lighting time can be provided in addition to depending on the battery capacity, and rotated with the light intensity changes, whether cloudy or sunny, maintains an optimum charging efficien- cy, charging to get the best results, extend the night illumination time. AVR microcontroller- based sys- tem used a controller chip, the whole column using a plurality of photosensitive sensor , sensor array to get the data of the light panel position , make the solar panels keep facing the strongest light for better chaging efficiency, to gather more power, longer aloe lights at night time. Compared with traditional lights, the introduction of microprocessor controlled intelligent lights, providing superior intelligence, scalability, solar street light provides a better performance, lowcost solution.
