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(zai)白天并不會(hui)亮起。
白天太陽能燈(deng)是屬于一(yi)個吸收的(de)(de)(de)狀態,等(deng)到(dao)夜晚,光(guang)(guang)線比較暗,且達到(dao)太陽能路燈(deng)放光(guang)(guang)的(de)(de)(de)要求之(zhi)后,便會開始亮起,從(cong)而滿(man)足夜晚正常使用。一(yi)般太陽能路燈(deng)是通(tong)過電(dian)壓控制開關(guan)的(de)(de)(de),如果出現一(yi)些特殊情(qing)況,導致(zhi)太陽能路燈(deng)的(de)(de)(de)輸出電(dian)壓變低(di),在(zai)設定好(hao)的(de)(de)(de)數值,也(ye)會出現太陽能路燈(deng)白天發光(guang)(guang)的(de)(de)(de)情(qing)況。
二、太陽能路燈白天一直亮什么原因
正常的(de)太(tai)(tai)陽能路燈(deng)白(bai)天是不會亮的(de),如果白(bai)天一直(zhi)亮燈(deng),說明太(tai)(tai)陽能路燈(deng)壞(huai)了(le),可能導致這種情(qing)況的(de)原因(yin)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(jian)測:操(cao)控器紅燈亮表(biao)(biao)明(ming)正在充電(dian)(dian),紅燈閃耀表(biao)(biao)明(ming)電(dian)(dian)池現(xian)已充滿了,操(cao)控器正在以(yi)脈沖的小電(dian)(dian)流(liu)充電(dian)(dian)。
太陽(yang)(yang)能(neng)板(ban):太陽(yang)(yang)能(neng)板(ban)的(de)銜接(jie)(jie)如不(bu)是很結實(shi)會不(bu)能(neng)正常充電(dian)(dian)(dian)(dian),一般的(de)表現為(wei)有(you)電(dian)(dian)(dian)(dian)壓(ya)(電(dian)(dian)(dian)(dian)壓(ya)表測驗),正常開路電(dian)(dian)(dian)(dian)壓(ya)在17.5V以上;可(ke)是沒有(you)電(dian)(dian)(dian)(dian)流(liu)。這種現象為(wei)電(dian)(dian)(dian)(dian)池(chi)板(ban)的(de)線沒有(you)銜接(jie)(jie)好(焊接(jie)(jie)出現虛焊或接(jie)(jie)頭不(bu)結實(shi)),排(pai)查辦法能(neng)夠直(zhi)接(jie)(jie)在電(dian)(dian)(dian)(dian)池(chi)板(ban)后面的(de)黑色(se)電(dian)(dian)(dian)(dian)器蓋翻開后,直(zhi)接(jie)(jie)用(yong)電(dian)(dian)(dian)(dian)壓(ya)、電(dian)(dian)(dian)(dian)流(liu)表檢測數據。如直(zhi)接(jie)(jie)從電(dian)(dian)(dian)(dian)池(chi)板(ban)的(de)鋁泊檢測都(dou)無電(dian)(dian)(dian)(dian)流(liu),表明電(dian)(dian)(dian)(dian)池(chi)板(ban)有(you)問題要替換。
2、物體遮蓋
如果(guo)太(tai)(tai)陽能(neng)(neng)電池板被掩(yan)(yan)蓋,也(ye)會導(dao)致太(tai)(tai)陽能(neng)(neng)路(lu)燈(deng)不能(neng)(neng)夠正常運用,大雪掩(yan)(yan)蓋,以及塵埃的掩(yan)(yan)蓋等狀況(kuang)。當這些掩(yan)(yan)蓋物掩(yan)(yan)蓋太(tai)(tai)陽能(neng)(neng)電池板今后,太(tai)(tai)陽能(neng)(neng)電池板的輸出電壓就會低于必定的值,太(tai)(tai)陽能(neng)(neng)路(lu)燈(deng)就會觸發(fa)點亮(liang)。
3、光敏電阻誤操控
光(guang)(guang)(guang)敏(min)電(dian)阻(zu)對光(guang)(guang)(guang)線特別敏(min)感,在光(guang)(guang)(guang)照強度(du)弱的時(shi)分電(dian)阻(zu)大,跟著(zhu)光(guang)(guang)(guang)線的變(bian)強,電(dian)阻(zu)值(zhi)下降。經過滑動變(bian)阻(zu)器(qi)能夠(gou)找到一個平衡點(dian),在光(guang)(guang)(guang)線較(jiao)強時(shi),光(guang)(guang)(guang)敏(min)電(dian)阻(zu)值(zhi)小。運(yun)用光(guang)(guang)(guang)敏(min)電(dian)阻(zu)具有必定的缺點(dian)。光(guang)(guang)(guang)敏(min)電(dian)阻(zu)對安裝要求比(bi)較(jiao)高,并(bing)且在雨天(tian)、陰天(tian)等狀況下容易發生誤操控。
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池板的輸出電壓(ya)作為控制信號(hao)的,在電壓(ya)低于一定程(cheng)度時(shi)開啟路燈(deng)(deng),在電壓(ya)高(gao)于一定程(cheng)度時(shi)關(guan)閉(bi)路燈(deng)(deng)。如(ru)果太陽(yang)能電池板電壓(ya)出現問題,低于一定程(cheng)度時(shi),即(ji)使在白(bai)天也會亮燈(deng)(deng)。
