造成led燈具死燈的原因是什么如題謝謝了

1、單(dan)元板設計時采用(yong)的IC輸出電壓高(gao)于(yu)LED燈的正常工作(zuo)電壓，2、燈的自身(shen)質量問題(ti)。

led死燈的常見原因有哪些

1、LED驅(qu)動電(dian)源(yuan)(yuan)(yuan)和(he)LED光源(yuan)(yuan)(yuan)的故(gu)障。這類故(gu)障幾率最高(gao)。LED燈具的毛(mao)病(bing)多為驅(qu)動電(dian)路毛(mao)病(bing)。LED光源(yuan)(yuan)(yuan)本(ben)身的封裝(zhuang)品(pin)質也(ye)會(hui)影響整燈的壽命，品(pin)質好的LED光源(yuan)(yuan)(yuan)成本(ben)較高(gao)，穩定性能(neng)也(ye)比較好。

2、散(san)熱和使用環(huan)境問題。這(zhe)與燈具本身的設計(ji)和使用環(huan)境有(you)關(guan)，如果(guo)本身設計(ji)的散(san)熱不合理，也(ye)會(hui)加(jia)速LED燈死(si)燈。如果(guo)使用的環(huan)境很惡劣，導(dao)致(zhi)LED燈具散(san)熱不良也(ye)會(hui)導(dao)致(zhi)加(jia)速燈具的故(gu)障率。

3、外(wai)部供電(dian)(dian)問題。LED抗(kang)浪涌的能力是(shi)比較差(cha)的，特(te)別(bie)是(shi)抗(kang)反向電(dian)(dian)壓能力。如果外(wai)部供電(dian)(dian)電(dian)(dian)壓不(bu)穩(wen)定，經常出(chu)現高電(dian)(dian)壓的浪涌，也會導致(zhi)LED燈具的故障。

led燈突然滅了是怎么回事

led燈(deng)通常(chang)是由多個led燈(deng)珠串(chuan)(chuan)聯在一(yi)起(qi)組成的燈(deng)帶(dai)(dai)，如(ru)果(guo)燈(deng)帶(dai)(dai)突然滅了，可以考慮某個燈(deng)珠壞了，把它拔掉，將(jiang)兩端再(zai)串(chuan)(chuan)聯起(qi)來即可恢復(fu)照明。
