led燈條上每個燈珠額定電壓多少

LED黃紅色的(de)燈(deng)珠的(de)最低電(dian)壓(ya)一般是(shi)1.8V-2.2V, 藍白綠(lv)色的(de)最低電(dian)壓(ya)是(shi)2.8V-3.2V。

LED可以直接發出紅、黃、藍、綠(lv)、青(qing)、橙、紫、白色的光。

最初LED用(yong)作儀(yi)器儀(yi)表的(de)(de)指示光源，后來(lai)各種光色的(de)(de)LED在(zai)交(jiao)通信號燈(deng)和(he)大面積(ji)顯(xian)示屏中得到了(le)廣泛應用(yong)，產生了(le)很(hen)好(hao)的(de)(de)經濟效益和(he)社會效益。

液晶電視背光燈珠如何判斷幾v幾W

液晶(jing)電(dian)視燈條燈條判斷，需(xu)要用萬用表測(ce)量接線端子(zi)電(dian)壓(ya)或看電(dian)路板上的標注電(dian)壓(ya)

電(dian)壓(ya)(ya)測量法LED背光燈供(gong)電(dian)板輸出電(dian)壓(ya)(ya)：LED燈條(tiao)的供(gong)電(dian)電(dian)壓(ya)(ya)是直流(liu)電(dian)壓(ya)(ya)，其電(dian)壓(ya)(ya)值一般(ban)在一百多伏到兩百余伏之間(jian)，因(yin)此，可以(yi)用萬用表直流(liu)電(dian)壓(ya)(ya)250V擋測該(gai)板輸出的電(dian)壓(ya)(ya)值就可以(yi)確(que)認它(ta)是否(fou)正常

判斷電壓(ya)的(de)步驟如(ru)下：

1.

需要使用的萬(wan)用表(biao),萬(wan)用表(biao)選擇二極(ji)管檔。

2.

觀測(ce)時,長腳為正。若表有讀(du)數,則此時紅(hong)表筆(bi)所測(ce)端為二極管的正極,同時發光(guang)二極管會發光(guang)。

3.

若沒有讀數(shu),則將表筆反過(guo)來(lai)再測一次。顯示的數(shu)字就是(shi)LED燈珠的電(dian)壓。

led燈條電壓一般是多少

單(dan)個LED燈珠，工作電(dian)壓大約是2.73.7伏，主要是看工作電(dian)流不能超標。

不同的品牌和產地，其(qi)工作(zuo)電(dian)(dian)流有差異。國產傳統的直徑5毫(hao)(hao)米的燈珠，標準工作(zuo)電(dian)(dian)流是(shi)22毫(hao)(hao)安(an)。進(jin)口標稱1W的燈珠，工作(zuo)電(dian)(dian)流是(shi)280毫(hao)(hao)安(an)。進(jin)口3W的高(gao)亮遠照燈珠，工作(zuo)電(dian)(dian)流是(shi)850毫(hao)(hao)安(an)。

以上(shang)就是(shi)(shi)天成小(xiao)編(bian)對于led電視燈條燈珠電壓(ya) led燈珠額定(ding)電壓(ya)是(shi)(shi)多少問題和相關(guan)問題的解答(da)了，希望對你有用(yong) 【責(ze)任編(bian)輯：燈漂亮(liang)】
