一、太陽能路燈白天會亮嗎

路燈一般都是晚上才會亮的，太陽能路燈也不例外，正常情況下，太陽能路燈在白天并不會亮起。

白天太(tai)陽能(neng)(neng)燈(deng)是(shi)屬于一個吸收的狀態，等到夜(ye)晚，光線比較暗，且(qie)達到太(tai)陽能(neng)(neng)路燈(deng)放光的要(yao)求之后(hou)，便會開(kai)始亮起，從(cong)而滿足夜(ye)晚正常(chang)使(shi)用。一般太(tai)陽能(neng)(neng)路燈(deng)是(shi)通過電壓(ya)控制開(kai)關(guan)的，如果出(chu)(chu)現一些特殊(shu)情況(kuang)，導致太(tai)陽能(neng)(neng)路燈(deng)的輸出(chu)(chu)電壓(ya)變低，在(zai)設定(ding)好的數值，也會出(chu)(chu)現太(tai)陽能(neng)(neng)路燈(deng)白天發光的情況(kuang)。

二、太陽能路燈白天一直亮什么原因

正常的太陽(yang)能(neng)路(lu)燈(deng)白天是不會亮的，如果(guo)白天一直(zhi)亮燈(deng)，說明太陽(yang)能(neng)路(lu)燈(deng)壞(huai)了(le)，可能(neng)導致(zhi)這種情況的原因有很(hen)多：

1、太陽能板在白天沒有經過操控器給電池充電

操(cao)控器檢測(ce)：操(cao)控器紅(hong)燈(deng)亮(liang)表明正在充(chong)電(dian)，紅(hong)燈(deng)閃(shan)耀(yao)表明電(dian)池現已充(chong)滿了(le)，操(cao)控器正在以(yi)脈沖(chong)的小電(dian)流充(chong)電(dian)。

太(tai)陽能板(ban)(ban)(ban)：太(tai)陽能板(ban)(ban)(ban)的銜(xian)接(jie)如(ru)不(bu)是很結(jie)實會不(bu)能正常充電(dian)(dian)(dian)(dian)(dian)，一般的表現(xian)為有電(dian)(dian)(dian)(dian)(dian)壓(ya)（電(dian)(dian)(dian)(dian)(dian)壓(ya)表測(ce)(ce)驗），正常開路電(dian)(dian)(dian)(dian)(dian)壓(ya)在(zai)17.5V以(yi)上；可(ke)是沒有電(dian)(dian)(dian)(dian)(dian)流。這種現(xian)象為電(dian)(dian)(dian)(dian)(dian)池板(ban)(ban)(ban)的線沒有銜(xian)接(jie)好（焊(han)接(jie)出(chu)現(xian)虛焊(han)或(huo)接(jie)頭不(bu)結(jie)實），排查辦法能夠直接(jie)在(zai)電(dian)(dian)(dian)(dian)(dian)池板(ban)(ban)(ban)后(hou)面的黑(hei)色電(dian)(dian)(dian)(dian)(dian)器蓋(gai)翻開后(hou)，直接(jie)用(yong)電(dian)(dian)(dian)(dian)(dian)壓(ya)、電(dian)(dian)(dian)(dian)(dian)流表檢測(ce)(ce)數據。如(ru)直接(jie)從電(dian)(dian)(dian)(dian)(dian)池板(ban)(ban)(ban)的鋁泊檢測(ce)(ce)都無電(dian)(dian)(dian)(dian)(dian)流，表明(ming)電(dian)(dian)(dian)(dian)(dian)池板(ban)(ban)(ban)有問題要替(ti)換。

2、物體遮蓋

如果太陽(yang)(yang)能(neng)(neng)電池板(ban)被掩蓋(gai)，也會導致太陽(yang)(yang)能(neng)(neng)路(lu)燈(deng)不能(neng)(neng)夠(gou)正常運用，大雪掩蓋(gai)，以及塵埃(ai)的(de)掩蓋(gai)等狀(zhuang)況。當這些(xie)掩蓋(gai)物掩蓋(gai)太陽(yang)(yang)能(neng)(neng)電池板(ban)今后，太陽(yang)(yang)能(neng)(neng)電池板(ban)的(de)輸出電壓就(jiu)會低于(yu)必定的(de)值，太陽(yang)(yang)能(neng)(neng)路(lu)燈(deng)就(jiu)會觸發點亮。

3、光敏電阻誤操控

光(guang)敏(min)(min)(min)電(dian)(dian)阻對光(guang)線特別敏(min)(min)(min)感，在光(guang)照強(qiang)度弱的時分(fen)電(dian)(dian)阻大(da)，跟著光(guang)線的變(bian)強(qiang)，電(dian)(dian)阻值下降。經過滑動變(bian)阻器(qi)能夠(gou)找到一個(ge)平衡點，在光(guang)線較強(qiang)時，光(guang)敏(min)(min)(min)電(dian)(dian)阻值小。運用光(guang)敏(min)(min)(min)電(dian)(dian)阻具有必定的缺點。光(guang)敏(min)(min)(min)電(dian)(dian)阻對安裝要(yao)求比較高(gao)，并且(qie)在雨(yu)天、陰天等狀況下容(rong)易發生誤(wu)操控。

4、太陽能電池板的電壓不對

太陽能電池板將太陽光能轉化為電能，光照越強，輸出電壓越高，光線越弱輸出光線越低。所以很多太陽能路燈是用電(dian)池(chi)板的輸出電(dian)壓(ya)作為控制信號(hao)的，在電(dian)壓(ya)低于一定(ding)程度時開(kai)啟路燈(deng)，在電(dian)壓(ya)高于一定(ding)程度時關閉路燈(deng)。如果太(tai)陽能電(dian)池(chi)板電(dian)壓(ya)出現問(wen)題(ti)，低于一定(ding)程度時，即使在白天也會亮燈(deng)。
