System Design of Intelligent Power Supply on Solar Street Light
Recently,solar power LED light is gradually substituted for traditional lamp for it has high performance,long working life,environment friendly,small supporting investment,and so on.It is applied for more and more areas due to these advantages.There are a lot of technical problems in solar power LED lighting system,such as,the short battery life,the unequal distribution of the annual solar energy etc.Therefore,the design of low cost,high performance controller is urgently required.In this paper,based on the analysis in battery charge and discharge charateristics,an intelligent controlled circuit,which has simple structure and full function,is proposed.It has adaptive solar power supply,power detect and remaining power calculation,both to ensure lighting system long-term reliable operation and fully meet the needs of the load.It also has network construction function which can ensure the consistency of the brightness of all the lights on the whole street,has communication and intelligent control function.The proposed design improves the efficiency of the solar panels,extends the service life of the battery,also ensures the normal lighting of the LEDlamp,reduces the cost,improve the system reliability.
