Design And Realization Of Solar Street Light In

At present, the problems of global energy and environment pollution are getting serious. The new energy of using environmental-friendly is becoming a topic which the researchers are concerned. The solar energy is being rapidly popularization and application as a new green energy by its advantages of inexhaustible, no pollution and regardless of the region.This article is for the design of the solar street lamps, Tibet region by reading literature about the research status at home and abroad and the application of solar photovoltaic power generation system. Then by understanding the working principle of solar street lights, analyzes its structure, and puts forward the design method of solar street light system, and through the analysis of the meteorological data of prefecture of Tibet and regional characteristics, determine the basic scheme of solar street light, make the system to achieve the optimal configuration. In addition, this paper analyzes the components and testing, the results show that solar panels photoelectric conversion efficiency higher than 18%; Battery can through the low temperature test and cycle test, and can meet the demand of rainy night lighting for 4 days; Controller in-35℃～55℃ scope can normal work. At the same time, the LED light source reaches IP65 rating and aging, thermal test, This topic through the test components, verify the reliability of the design.
