This design uses class of S spiral with the highest wind energy utilization rate, and the surface has materials that can absorb solar energy, its structure built in simple and the design fit standard proportion lamp. This design has the advantages of beautiful apnearance, easv to produce, has the very big use value.展开更多
将高压气体放电灯(高压钠灯)用于光伏照明系统,再合理选择系统的各部分容量使之配合,即可在控制成本的前提下组成高效光伏照明系统。为了配合高压气体放电灯的稳定工作,研制了一个直流升压电路和一个高频逆变电路。配以镇流、启辉电路,...将高压气体放电灯(高压钠灯)用于光伏照明系统,再合理选择系统的各部分容量使之配合,即可在控制成本的前提下组成高效光伏照明系统。为了配合高压气体放电灯的稳定工作,研制了一个直流升压电路和一个高频逆变电路。配以镇流、启辉电路,实现了250W高压气体放电灯在高频电源下稳定工作,为照明提供了稳定、高转换效率的电光源,从而满足道路交通照明的要求。在此光伏照明系统中,还实现了太阳能最大功率点跟踪(MaximumPower Point Tracking,MPPT)技术。这样在充电过程中,即使在不同的光照和温度条件下,充电电路也能自动调整,使太阳能电池始终工作在最大功率输出状态。展开更多
