對于太陽能路燈來說，太陽能白天充電晚上點燈，是對太陽能照明系統的基本要求。電路中不另配光傳感器，以光伏板輸出電壓為準，這也是太陽能系統通行的做法。那么太陽能路燈白天充電不亮燈晚上亮燈是怎么做到呢?下面太陽(yang)能路(lu)燈廠家明光恒輝就為大家介紹下。

太(tai)陽(yang)(yang)能控(kong)制(zhi)器內具有檢(jian)測模塊，一般有兩種方法：利用光(guang)敏(min)電(dian)(dian)阻檢(jian)測太(tai)陽(yang)(yang)光(guang)線的(de)強弱;利用電(dian)(dian)壓檢(jian)測模塊檢(jian)測太(tai)陽(yang)(yang)能電(dian)(dian)池板的(de)輸出電(dian)(dian)壓。

方法一：利用光敏電阻檢測光線強弱

光(guang)(guang)(guang)(guang)(guang)(guang)敏(min)(min)(min)(min)電(dian)(dian)阻(zu)(zu)對(dui)光(guang)(guang)(guang)(guang)(guang)(guang)線(xian)特別敏(min)(min)(min)(min)感，在光(guang)(guang)(guang)(guang)(guang)(guang)照強度(du)弱(ruo)的時候電(dian)(dian)阻(zu)(zu)大(da)，隨(sui)著(zhu)光(guang)(guang)(guang)(guang)(guang)(guang)線(xian)的變強，電(dian)(dian)阻(zu)(zu)值下(xia)降(jiang)。所以(yi)，利用這個特性可(ke)以(yi)檢(jian)測太陽光(guang)(guang)(guang)(guang)(guang)(guang)線(xian)的強弱(ruo)，輸出給太陽能控制(zhi)器(qi)，作為路燈開啟(qi)和關(guan)閉(bi)的控制(zhi)信號。光(guang)(guang)(guang)(guang)(guang)(guang)敏(min)(min)(min)(min)電(dian)(dian)阻(zu)(zu)和簡(jian)單的光(guang)(guang)(guang)(guang)(guang)(guang)敏(min)(min)(min)(min)電(dian)(dian)路。通過滑動變阻(zu)(zu)器(qi)可(ke)以(yi)找到一(yi)個平衡點，在光(guang)(guang)(guang)(guang)(guang)(guang)線(xian)較強時，光(guang)(guang)(guang)(guang)(guang)(guang)敏(min)(min)(min)(min)電(dian)(dian)阻(zu)(zu)值小(xiao)，三(san)(san)極(ji)管基極(ji)是高(gao)電(dian)(dian)平，三(san)(san)極(ji)管不(bu)導(dao)通，LED不(bu)亮(liang)(liang);在光(guang)(guang)(guang)(guang)(guang)(guang)線(xian)較弱(ruo)時，光(guang)(guang)(guang)(guang)(guang)(guang)敏(min)(min)(min)(min)電(dian)(dian)阻(zu)(zu)阻(zu)(zu)值大(da)，基極(ji)是低(di)電(dian)(dian)平，三(san)(san)極(ji)管導(dao)通，LED被點亮(liang)(liang)。但是，利用光(guang)(guang)(guang)(guang)(guang)(guang)敏(min)(min)(min)(min)電(dian)(dian)阻(zu)(zu)具有一(yi)定(ding)的缺點。光(guang)(guang)(guang)(guang)(guang)(guang)敏(min)(min)(min)(min)電(dian)(dian)阻(zu)(zu)對(dui)安裝要(yao)求比較高(gao)，并(bing)且在雨天(tian)(tian)、陰天(tian)(tian)等情(qing)況下(xia)容易發生誤控制(zhi)。

方法二：檢測太陽能電池板的電壓

太陽能(neng)(neng)電池(chi)板將太陽光(guang)能(neng)(neng)轉化(hua)為(wei)(wei)電能(neng)(neng)，光(guang)照越強，輸出電壓越高，光(guang)線(xian)越弱輸出光(guang)線(xian)越低。所以(yi)，可以(yi)利(li)用電池(chi)板的輸出電壓作為(wei)(wei)依據，在(zai)電壓低于(yu)一定(ding)(ding)程(cheng)(cheng)度(du)(du)時開(kai)啟路(lu)燈，在(zai)電壓高于(yu)一定(ding)(ding)程(cheng)(cheng)度(du)(du)時關閉路(lu)燈。該方(fang)式可以(yi)忽略(lve)安裝所帶來的影(ying)響，且較為(wei)(wei)直接。
