怎樣測量led貼片好壞

可以用(yong)指針式萬(wan)用(yong)表R*10K電(dian)阻(zu)檔測(ce)(ce)量(liang)LED貼片燈(deng)珠(zhu)(zhu)的(de)(de)正(zheng)反(fan)向電(dian)阻(zu)。測(ce)(ce)正(zheng)向電(dian)阻(zu)時，燈(deng)珠(zhu)(zhu)會發出微(wei)光(guang)。測(ce)(ce)反(fan)向電(dian)阻(zu)時燈(deng)珠(zhu)(zhu)不會發光(guang)。則可判斷燈(deng)珠(zhu)(zhu)是好的(de)(de)。若正(zheng)反(fan)向電(dian)阻(zu)值都為無窮大，則可判斷燈(deng)珠(zhu)(zhu)已經斷路(lu)損壞(huai)。燈(deng)珠(zhu)(zhu)絕大部分是斷路(lu)損壞(huai)。

怎樣檢測LED貼片燈珠

現在的(de)(de)(de)(de)LED燈珠，它的(de)(de)(de)(de)壓降一(yi)(yi)般(ban)在3v左(zuo)右，所(suo)以一(yi)(yi)般(ban)的(de)(de)(de)(de)萬用表是測(ce)不了它的(de)(de)(de)(de)。普通(tong)指針表的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)阻(zu)(zu)檔電(dian)(dian)(dian)(dian)壓一(yi)(yi)般(ban)在1.5V，有(you)的(de)(de)(de)(de)只有(you)在高阻(zu)(zu)檔（*10K檔）用9V或15V電(dian)(dian)(dian)(dian)池，所(suo)以指針表要測(ce)量LeD燈珠的(de)(de)(de)(de)話(hua)要打(da)到最高電(dian)(dian)(dian)(dian)阻(zu)(zu)檔測(ce)量，否則沒(mei)用的(de)(de)(de)(de)，當然(ran)這時候的(de)(de)(de)(de)亮(liang)度(du)是很小，可能看不清，只能看正反(fan)電(dian)(dian)(dian)(dian)阻(zu)(zu)值的(de)(de)(de)(de)大小進行(xing)判斷(duan)咯(ge)。而數(shu)字表的(de)(de)(de)(de)二極管檔的(de)(de)(de)(de)輸出電(dian)(dian)(dian)(dian)壓也(ye)不高，一(yi)(yi)般(ban)在2.5V以下，所(suo)以測(ce)量LED燈珠也(ye)不行(xing)，最好的(de)(de)(de)(de)辦法是外(wai)加電(dian)(dian)(dian)(dian)測(ce)量。如果(guo)有(you)很多(duo)燈珠要進行(xing)測(ce)量的(de)(de)(de)(de)話(hua)，可以搭一(yi)(yi)個(ge)恒流電(dian)(dian)(dian)(dian)源進行(xing)測(ce)量

led燈珠測試儀測評

一、如果家里面備(bei)有萬用(yong)表，那(nei)么(me)萬用(yong)表是很方便的(de)一種(zhong)檢(jian)測LED貼片燈珠好壞的(de)測試工具。

我(wo)們(men)可以通(tong)過利用(yong)萬(wan)用(yong)表的二極管檔位來測(ce)試貼片(pian)燈珠(zhu)好壞。

使用方法是將(jiang)紅表筆接(jie)正極，黑表筆接(jie)負極，如(ru)果(guo)接(jie)通(tong)時有蜂(feng)嗚聲表示LED貼(tie)片燈珠(zhu)壞，如(ru)果(guo)燈珠(zhu)亮則表明此(ci)LED貼(tie)片燈珠(zhu)是好的。

所以，用(yong)萬用(yong)表測(ce)試低電壓led貼片燈珠(zhu)是比較常用(yong)的一種(zhong)判斷LED燈珠(zhu)好(hao)壞的方(fang)法。

二、如果經常(chang)LED燈珠應用開(kai)發或測(ce)試，可(ke)以(yi)X寶買一(yi)個LED測(ce)試筆。

這款LED燈珠(zhu)(zhu)測試(shi)筆(bi)可以(yi)比(bi)較直觀(guan)測試(shi)和(he)配(pei)合(he)點亮LED燈珠(zhu)(zhu)來判斷LED的好壞，而且價格也不(bu)貴，幾(ji)十元就可以(yi)買(mai)到一只了。

三、LED燈(deng)珠測試(shi)儀(yi)，也是(shi)一種比較省事的LED貼片燈(deng)珠檢測工(gong)具(ju)。

以(yi)上(shang)就(jiu)是天(tian)成小編對(dui)于貼(tie)片led燈珠測試 怎樣(yang)測量貼(tie)片led的好壞問(wen)題和相關問(wen)題的解答了(le)，希(xi)望對(dui)你有用 【責任編輯：燈漂亮】
