大(da)家(jia)好我是天(tian)(tian)成(cheng)照明LED燈珠(zhu)廠家(jia)小編燈漂亮今天(tian)(tian)我們來介紹led燈珠(zhu)變12 6v的led燈珠(zhu)怎么接12v電源的問(wen)(wen)題，以下(xia)就是燈漂亮對此(ci)問(wen)(wen)題和相關問(wen)(wen)題的歸(gui)納(na)整(zheng)理,一起來看(kan)(kan)看(kan)(kan)吧(ba)。 文章目錄導航:
6v燈珠led改12v 如果是LED燈的(de)話，直接串(chuan)(chuan)聯電阻(zu)分(fen)壓(ya)就(jiu)好。 紅色(se)(se)、黃(huang)色(se)(se)的(de)LED壓(ya)降(jiang)是2.2V 白(bai)色(se)(se)，藍色(se)(se)，綠色(se)(se)是3V。 那上(shang)面的(de)LED應該都是指示用的(de)，所以電流(liu)不(bu)用太大，取0.01A就(jiu)好了(le)，然后需(xu)要(yao)串(chuan)(chuan)聯電阻(zu)的(de)阻(zu)值(zhi)=（輸(shu)入電壓(ya)-LED壓(ya)降(jiang)*串(chuan)(chuan)聯LED的(de)個數）/0.01，算(suan)出來取一(yi)個附件比較常(chang)見的(de)阻(zu)值(zhi)就(jiu)好了(le)，電阻(zu)就(jiu)用1/4W就(jiu)可以了(le)。
用220v的LED燈怎么改成12v的 用220V的電(dian)(dian)(dian)(dian)壓(ya)(ya)的lad燈(deng)(deng)，并不(bu)代表led燈(deng)(deng)燈(deng)(deng)板(燈(deng)(deng)珠)是使(shi)用220V。Led燈(deng)(deng)使(shi)用配(pei)套的驅動(dong)器，它的輸(shu)(shu)(shu)(shu)入為(wei)220Ⅴ，但它經降壓(ya)(ya)整流(liu)后的輸(shu)(shu)(shu)(shu)出(chu)直(zhi)(zhi)(zhi)流(liu)電(dian)(dian)(dian)(dian)壓(ya)(ya)卻是與燈(deng)(deng)板使(shi)用的任(ren)何直(zhi)(zhi)(zhi)流(liu)電(dian)(dian)(dian)(dian)壓(ya)(ya)都一致。如果燈(deng)(deng)板(燈(deng)(deng)珠)使(shi)用電(dian)(dian)(dian)(dian)壓(ya)(ya)為(wei)12V，那么驅動(dong)器輸(shu)(shu)(shu)(shu)入盡管是使(shi)用220V交(jiao)流(liu)電(dian)(dian)(dian)(dian)，但它的直(zhi)(zhi)(zhi)流(liu)輸(shu)(shu)(shu)(shu)出(chu)也(ye)只能是12V。如果說12V的led燈(deng)(deng)板不(bu)使(shi)用220V交(jiao)流(liu)電(dian)(dian)(dian)(dian)源，可用12V直(zhi)(zhi)(zhi)流(liu)電(dian)(dian)(dian)(dian)源(但通常還(huan)是由220V電(dian)(dian)(dian)(dian)轉換)，12V蓄電(dian)(dian)(dian)(dian)瓶、干(gan)電(dian)(dian)(dian)(dian)池供(gong)電(dian)(dian)(dian)(dian)等直(zhi)(zhi)(zhi)流(liu)電(dian)(dian)(dian)(dian)源。 有一個30v100w的led燈珠改成12v供電如何是好 的(de)燈(deng)珠(zhu)是集成的(de)吧集成的(de)燈(deng)珠(zhu)一(yi)般(ban)需要的(de)是恒流供(gong)電，你(ni)若使(shi)用12V的(de)恒壓供(gong)電，需要再加一(yi)個DC-DC的(de)升壓恒流模塊來實現。 怎么才能把4伏的LED燈改成十二伏的 如(ru)果是(shi)(shi)12V輸入的(de)(de)(de)，有紅綠藍三根并(bing)排(pai)的(de)(de)(de)線+一(yi)根其它顏色的(de)(de)(de)線，接法就(jiu)是(shi)(shi)紅綠藍分別對(dui)應三色LED燈，剩下的(de)(de)(de)那根電(dian)源線就(jiu)是(shi)(shi)公用的(de)(de)(de)正極(ji)(或負極(ji)，因(yin)板而(er)異(yi))。 如(ru)果是紅黑兩(liang)根(gen)在(zai)一起，且(qie)燈板(ban)上對(dui)(dui)應(ying)(ying)的(de)是V+,V-;另(ling)外兩(liang)根(gen)不(bu)是和(he)LED燈珠相對(dui)(dui)應(ying)(ying)的(de)顏色(se)線，且(qie)燈板(ban)上對(dui)(dui)應(ying)(ying)的(de)是信(xin)號(hao)(hao)輸入，則說明(ming)接法就是V+接電(dian)源(yuan)正(zheng)極，V-接電(dian)源(yuan)負極，另(ling)外兩(liang)根(gen)線對(dui)(dui)應(ying)(ying)的(de)是信(xin)號(hao)(hao)輸入線，接的(de)是LED控制(zhi)器信(xin)號(hao)(hao)控制(zhi)端。
