大家好今(jin)天來(lai)介紹led燈(deng)珠白光的溫度(du)(燈(deng)珠色溫標準范圍)的問題，以下是小(xiao)編(bian)對此(ci)問題的歸納整理，來(lai)看看吧。 文章目錄列表:
燈珠色溫cn表示方法Led燈珠(zhu)白光(guang)(guang)和黃(huang)光(guang)(guang)是用(yong)色溫值表示(shi)的，6000~6800K為白光(guang)(guang)，4000~4500K為黃(huang)光(guang)(guang)。
led燈珠溫度正常是多少led燈珠的(de)(de)工(gong)作(zuo)溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)(du)(du)一(yi)般在40度(du)(du)(du)(du)(du)(du)(du)以下(xia)，結壓以不超(chao)過(guo)三十度(du)(du)(du)(du)(du)(du)(du)為宜。根據單顆(ke)LED白燈老(lao)化時(shi)的(de)(de)數據來看(kan)，LED白燈如果(guo)只有(you)一(yi)個點(dian)亮工(gong)作(zuo)，同時(shi)，它所(suo)處(chu)的(de)(de)環境溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)(du)(du)是30度(du)(du)(du)(du)(du)(du)(du)的(de)(de)話，那(nei)么(me)，單顆(ke)LED白燈工(gong)作(zuo)時(shi)的(de)(de)支(zhi)架溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)(du)(du)不會(hui)超(chao)過(guo)45度(du)(du)(du)(du)(du)(du)(du)。這(zhe)個時(shi)候(hou)，這(zhe)顆(ke)LED的(de)(de)壽命會(hui)很理想。LED燈珠工(gong)作(zuo)溫(wen)(wen)(wen)度(du)(du)(du)(du)(du)(du)(du)太(tai)高可(ke)能會(hui)熄(xi)滅，原因如下(xia)： 1、LED中(zhong)有(you)一顆內部(bu)的金(jin)線(xian)(xian)虛焊，熱(re)脹冷縮的緣故，當(dang)點(dian)亮一段時間(jian)后LED的硅膠膨(peng)脹帶(dai)出(chu)金(jin)線(xian)(xian)造成(cheng)熄滅(mie)，熄滅(mie)后溫度降(jiang)低(di)，金(jin)線(xian)(xian)又(you)接觸到發光晶片(pian)，LED重新點(dian)亮。測試方法，LED突(tu)然熄滅(mie)后按一按LED，看(kan)(kan)看(kan)(kan)會(hui)不會(hui)把它(ta)按亮，量一下電源(yuan)輸出(chu)端(duan)電壓(ya)(ya)，看(kan)(kan)是否有(you)9V以(yi)上的電壓(ya)(ya)，如果有(you)的話應該是LED的問題。 2、電源(yuan)質量問題(ti)(ti)，電源(yuan)的過(guo)溫保護(hu)過(guo)于靈敏(min)，造成有(you)時亮有(you)時滅的問題(ti)(ti)。（1）電流過(guo)載(zai)（超負荷工作）（2）電源(yuan)上電容問題(ti)(ti)（3）其他焊接問題(ti)(ti)3、焊接虛(xu)焊，LED焊盤(pan)(pan)或者引線焊盤(pan)(pan)的虛(xu)焊。 led燈溫度對照表LED燈具的溫度： 溫(wen)(wen)度過高容易造成燈珠光衰嚴重(zhong)，甚(shen)至(zhi)帶來安全隱患。一(yi)般當燈泡達到熱平衡(heng)后，燈珠引腳溫(wen)(wen)度不高于65℃，散熱器表(biao)面(mian)溫(wen)(wen)度不高于55℃即為合格品。 led色溫對照表LED色溫(wen)常識及LED色溫(wen)對照表
