12vLED照明器具蓄電池的連接方法

12v的燈直接連(lian)接就可以了。

4個3v、LED串(chuan)聯連接12v電池以100歐(ou)姆左右的電阻作為(wei)限制(zhi)流串(chuan)聯連接。

LED燈珠未亮時，LED燈需要供給220V的電(dian)力時，如(ru)果12v連接電(dian)池也無(wu)法點亮。首先，確(que)認手邊的LED燈是多少V后，進行改造。

12v電(dian)池能(neng)直接連(lian)接到(dao)40W的(de)(de)(de)(de)LED燈(deng)(deng)嗎(ma)?這取決(jue)于你的(de)(de)(de)(de)40W燈(deng)(deng)所要求(qiu)的(de)(de)(de)(de)電(dian)壓(ya)有(you)多少。同樣是40W的(de)(de)(de)(de)LED燈(deng)(deng)，有(you)電(dian)壓(ya)220V的(de)(de)(de)(de)、60V的(de)(de)(de)(de)、24V的(de)(de)(de)(de)、12v的(de)(de)(de)(de)等。如果購買輸入(ru)電(dian)壓(ya)的(de)(de)(de)(de)要求(qiu)

12v的LED燈連(lian)接(jie)到48V的電動(dong)車電池(chi)。怎么連(lian)接(jie)呢。百度用(yong)DC48轉(zhuan)DC12V的轉(zhuan)換器，20元左(zuo)右(you)1條(tiao)，轉(zhuan)換器的3條(tiao)線，一般是紅黃(huang)黑(hei)色(se)(se)，紅色(se)(se)是高壓正極，黃(huang)色(se)(se)是12v

12v的(de)電(dian)(dian)(dian)池能連接到(dao)24V的(de)LED燈(deng)嗎24V的(de)LED燈(deng)不(bu)能直接連接到(dao)12v的(de)電(dian)(dian)(dian)池。電(dian)(dian)(dian)壓不(bu)合適(shi)就不(bu)點燈(deng)。需(xu)要(yao)買12v對24V的(de)電(dian)(dian)(dian)源轉換器。

12v汽車電池如何點亮LED燈泡LED燈泡有(you)3伏(fu)特(te)(te)和4伏(fu)特(te)(te)，3伏(fu)特(te)(te)用4個(ge)電燈泡串聯連接(jie)，4伏(fu)特(te)(te)用3個(ge)電燈泡串聯連接(jie)，最(zui)簡單。如果(guo)不(bu)那(nei)樣做的話，就(jiu)使用降壓器。

怎樣用12v的電(dian)池制作LED燈，因(yin)為(wei)電(dian)池電(dian)壓變動，最(zui)低10V左右，有可(ke)能達到最(zui)高14V。因(yin)此無法(fa)連(lian)接4個(ge)LED。連(lian)接3個(ge)串聯，追(zhui)加1個(ge)電(dian)阻就可(ke)以了。電(dian)阻14V可(ke)以計算為(wei)20毫安

12v蓄電池如(ru)何(he)連接LED燈(deng)LED的鍵低電壓才好，最初安裝時LED如(ru)繩子那樣(yang)，一(yi)(yi)端連接正極(ji)而一(yi)(yi)端連接負極(ji)的看ok燈(deng)帶是否是12伏，如(ru)果是那樣(yang)直接對(dui)應正負極(ji)連接的話ok，如(ru)果是其他(ta)電壓的話有點麻煩。
