     過去，我們使用的路燈需要連接電源才能正常工作，且安裝復雜，消耗人力、物力、財力。現在，太陽能路燈的出現很好的解決了過去路燈的一些弊端，具有環保、節能，高效等優點，那么，可能有些人會存在一個疑慮，就是太陽能路燈需要外接電源嗎?深圳源碼太陽能路燈廠家技術人員為大家解答：
　　太陽能路燈是(shi)一種(zhong)新型的(de)節(jie)能(neng)環保產品，它主要是(shi)通過吸收太(tai)陽光從而轉化(hua)成(cheng)電能(neng)并儲存(cun)在(zai)蓄電池中，由(you)蓄電池給光源供(gong)電，因此(ci)，它是(shi)不需要外(wai)接電源的(de)，太(tai)陽能(neng)路(lu)燈系統是(shi)一個獨立的(de)發電系統。

　　太陽能路燈的轉化原理：

　　白天，在光照條(tiao)件(jian)下(xia)，太陽(yang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)組件(jian)產(chan)生一定(ding)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動勢，通(tong)過(guo)組件(jian)的(de)串并(bing)聯形(xing)成太陽(yang)能電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)方陣(zhen)，使(shi)得方陣(zhen)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓達到系統輸(shu)入電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓的(de)要求。再(zai)通(tong)過(guo)充(chong)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)控制(zhi)(zhi)器(qi)(qi)(qi)對蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)進(jin)行(xing)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，將由光能轉(zhuan)換而來的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)能貯存起來。晚(wan)上(shang)，蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)組為逆變器(qi)(qi)(qi)提供輸(shu)入電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，通(tong)過(guo)逆變器(qi)(qi)(qi)的(de)作用，將直流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)轉(zhuan)換成交流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，輸(shu)送到配(pei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)柜，由配(pei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)柜的(de)切換作用進(jin)行(xing)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)組的(de)放(fang)(fang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)情況由控制(zhi)(zhi)器(qi)(qi)(qi)進(jin)行(xing)控制(zhi)(zhi)，保證蓄(xu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)正常使(shi)用。

　　太陽能路燈是采(cai)用(yong)晶體硅太陽能電(dian)池(chi)(chi)供(gong)電(dian)，免維護閥控(kong)式密封(feng)蓄電(dian)池(chi)(chi)(膠體電(dian)池(chi)(chi))儲存電(dian)能，無(wu)需鋪設線纜、無(wu)需交流(liu)供(gong)電(dian)、不產生電(dian)費;采(cai)用(yong)直(zhi)流(liu)供(gong)電(dian)、控(kong)制;具有穩定性好、壽命(ming)長、發光效率(lv)高，安裝(zhuang)維護簡便、安全性能高、節能環保、經(jing)濟實用(yong)等優點(dian)。

　　以上就是關于太陽能路燈需要外接電源的講解就介紹到這，太陽能路燈使用太陽能光伏電池提供電能，太陽能作為一種綠色環保的新能源，“取之不竭、用之不盡”。充分利用太陽能資源，對緩解常規能源緊張的情況有積極意義。
