Ⅰ太阳能在城市道路照明中的应用摘要随着世界能源危机的加剧，各国都在寻求解决能源危机的办法，一条道路是寻求新能源和可再生能源的利用；另一条是寻求新的节能技术，降低能源的消耗，提高能源的利用效率。太阳能是地球上最直接最普遍也是最清洁的能源，太阳能作为一种巨量可再生能源，每天达到地球表面的辐射能大约等于2.5亿万桶石油，可以说是取之不尽、用之不竭。LED的光谱几乎全部集中于可见光频段，所以发光效率高，一般人都认为，节能灯可节能4/5是伟大的创举，但LED比节能灯还要节能1/4，这是固体光源更伟大的改革，太阳能LED照明集成了太阳能与LED的优点。本文对太阳能LED路灯系统的应用做了较深入探讨与介绍。关键词太阳能电池，LED，铅酸蓄电池，充放电控制器ⅡABSTRACTTurnworsealongwiththeenergycrisisofworld,allcountriesareallatlookforthewayofsolvetheenergycrisis,aroadislookforthenewenergyandcanrenewableenergyofexploitation;Anotheristolookfortheneweconomyenergytechnique,loweringthedepletionoftheenergy,raisingtheexploitationefficiencyoftheenergy.Thesolarenergyisthemostdirectlythemostwidespreadisalsothemostdetergentenergyontheearth,thesolarenergybeakindofhugequantitycanrenewableenergy,attaintheradiationoftheEarthsurfaceandcanbeequalto2.5apetroleumofhundredmillionsabouteveryday,cansayistakeitnotexhausted,useitnotover.TheLEDspectrumisalmostallconcentratedinitisthusclearthatthelightsegment,sogiveoutlighttheefficiencyhigh,theordinarypeopleallthink,economyenergythelightcaneconomizeonenergy4/5isagreatunprecedentedundertaking,buttheLEDcomparetoeconomizeonenergythelighttostillneedtoeconomizeonenergy1/4,thisisthegreaterreformofthesolidlightsource.ThesolarenergyLEDilluminatestogathersolarenergyandLEDadvantage.TheapplicationofthistexttothesolarenergyLEDstreetlampsystemdidthemorethoroughstudyandintroductions.Keywordssolarbattery，LED，plumbumandvitriolstoragebattery，ChargeanddischargeController目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc136160690"摘要ⅠHYPERLINK\l"_Toc136160691"ABSTRACTⅡHYPERLINK\l"_Toc136160692"目录PAGEREF_Toc136160692\h1HYPERLINK\l"_Toc136160693"1绪论PAGEREF_Toc136160693\h1HYPERLINK\l"_Toc136160694"1．1课题背景PAGEREF_Toc136160694\h1HYPERLINK\l"_Toc136160695"1.2太阳能的利用可行性分析PAGEREF_Toc136160695\h2HYPERLINK\l"_Toc136160696"1.3太阳能能源的现状及前景PAGEREF_Toc136160696\h4HYPERLINK\l"_Toc136160697"2太阳能路灯系统结构PAGEREF_Toc136160697\h6HYPE
