怎樣判斷led燈珠電壓電流

判斷led燈珠(zhu)電(dian)壓(ya)電(dian)流(liu)可(ke)用(yong)萬用(yong)表(biao)測(ce)燈珠(zhu)的端(duan)電(dian)壓(ya)和電(dian)流(liu)。

一般LED燈珠單(dan)顆電(dian)(dian)壓(ya)是3.0-3.4V，不(bu)(bu)(bu)過(guo)現在LED產品種類(lei)繁多(duo)(duo)，有(you)許多(duo)(duo)燈珠內部雙芯(xin)片(pian)(pian)甚至三芯(xin)片(pian)(pian)串聯(lian)，包括現在市面(mian)上(shang)存(cun)在高壓(ya)芯(xin)片(pian)(pian)（原(yuan)理也(ye)(ye)是多(duo)(duo)顆芯(xin)片(pian)(pian)串聯(lian)），所以單(dan)純看(kan)外觀外行人無(wu)法看(kan)出電(dian)(dian)壓(ya)是多(duo)(duo)少的，至于電(dian)(dian)流(liu)(liu)，不(bu)(bu)(bu)同功率的燈珠電(dian)(dian)流(liu)(liu)也(ye)(ye)不(bu)(bu)(bu)一樣，這個更加看(kan)不(bu)(bu)(bu)出來了。比如2835燈珠有(you)0.2W的，有(you)0.5W的，有(you)1W的，分別(bie)對應的電(dian)(dian)流(liu)(liu)也(ye)(ye)不(bu)(bu)(bu)一樣。

貼片led燈珠電流和功率怎么測量

對貼片led燈珠的(de)電(dian)(dian)流(liu)測量，用萬用表或直流(liu)電(dian)(dian)流(liu)表串入燈珠供電(dian)(dian)線(xian)路中就可測量(與測一(yi)般電(dian)(dian)子元件的(de)電(dian)(dian)流(liu)一(yi)樣)，注(zhu)意正(zheng)、負極。

對(dui)其功(gong)(gong)率(lv)測量，測出電(dian)流(liu)后乘上(shang)供電(dian)電(dian)壓(ya)即是(shi)其即時實用功(gong)(gong)率(lv)但不是(shi)Led燈珠的額(e)定功(gong)(gong)率(lv)，因Led燈珠的導通電(dian)壓(ya)和工作(zuo)電(dian)流(liu)都是(shi)有個范圍的，準確的功(gong)(gong)率(lv)應當以該(gai)型號(hao)燈珠的參(can)數為準。

led燈珠怎么測試電流量

你是(shi)要測LED燈泡(pao)的輸入電(dian)(dian)(dian)(dian)流(liu)(liu)還(huan)是(shi)LED燈泡(pao)燈珠的工(gong)作(zuo)電(dian)(dian)(dian)(dian)流(liu)(liu)，如(ru)果是(shi)輸入電(dian)(dian)(dian)(dian)流(liu)(liu)用(yong)電(dian)(dian)(dian)(dian)氣(qi)參(can)數儀就可(ke)以了，只要把LED燈泡(pao)接(jie)(jie)在通(tong)過參(can)數儀的電(dian)(dian)(dian)(dian)壓插頭上點(dian)亮(liang)那(nei)(nei)參(can)數儀能直接(jie)(jie)顯示電(dian)(dian)(dian)(dian)流(liu)(liu)讀(du)數，如(ru)果是(shi)要測燈珠工(gong)作(zuo)電(dian)(dian)(dian)(dian)流(liu)(liu)那(nei)(nei)要把燈泡(pao)打開，把電(dian)(dian)(dian)(dian)流(liu)(liu)表(biao)(biao)或者(zhe)萬用(yong)表(biao)(biao)穿在燈珠與電(dian)(dian)(dian)(dian)源直接(jie)(jie)通(tong)電(dian)(dian)(dian)(dian)點(dian)亮(liang)燈泡(pao)看表(biao)(biao)讀(du)書

LED 燈珠怎么測試電流量

led燈珠(zhu)使用(yong)時都有串聯電(dian)阻，led燈珠(zhu)工(gong)作(zuo)時，用(yong)萬用(yong)表測量這個電(dian)阻兩端電(dian)壓，除以電(dian)阻就是(shi)led的工(gong)作(zuo)電(dian)流。

LED燈不亮了怎么測量燈珠的電流

由于LED燈(deng)的(de)特性,點亮的(de)電流(liu)(liu)應(ying)是(shi)低壓直流(liu)(liu)電,故應(ying)將(jiang)數(shu)字萬(wan)用(yong)(yong)表(biao)擋(dang)位撥向直流(liu)(liu)電流(liu)(liu)擋(dang),然(ran)后(hou)找到LED燈(deng)板上(shang)經過整流(liu)(liu)后(hou)的(de)直流(liu)(liu)輸入處,將(jiang)其斷(duan)(duan)開,再將(jiang)數(shu)字萬(wan)用(yong)(yong)表(biao)的(de)表(biao)筆串接到斷(duan)(duan)口處,通電后(hou)LED燈(deng)被點亮,此時萬(wan)用(yong)(yong)表(biao)顯示(shi)的(de)電流(liu)(liu)量(liang)是(shi)總流(liu)(liu)量(liang),以總流(liu)(liu)量(liang)除以LED燈(deng)的(de)數(shu)量(liang),就得(de)到每一個(ge)(ge)LED燈(deng)通過的(de)電流(liu)(liu)值(zhi),例如:總流(liu)(liu)量(liang)為(wei)1毫(hao)安(等于1000微(wei)安),LED燈(deng)的(de)數(shu)量(liang)為(wei)100,那么(me)1000÷100＝10(微(wei)安)即每一個(ge)(ge)LED燈(deng)通過的(de)電流(liu)(liu)為(wei)10微(wei)安.不防試(shi)一試(shi).(請注意安全(quan),整流(liu)(liu)前是(shi)220v的(de)電壓)。
