led死燈的常見原因有哪些

1、LED驅動電源(yuan)(yuan)和LED光(guang)(guang)源(yuan)(yuan)的(de)故障。這類故障幾(ji)率(lv)最高。LED燈具的(de)毛病多(duo)為驅動電路毛病。LED光(guang)(guang)源(yuan)(yuan)本身的(de)封裝品質(zhi)也會影(ying)響整(zheng)燈的(de)壽命(ming)，品質(zhi)好(hao)的(de)LED光(guang)(guang)源(yuan)(yuan)成本較高，穩定性(xing)能(neng)也比較好(hao)。

2、散(san)熱和使(shi)用(yong)環(huan)(huan)境(jing)問題。這(zhe)與燈(deng)具(ju)本(ben)身的設計和使(shi)用(yong)環(huan)(huan)境(jing)有關，如果(guo)本(ben)身設計的散(san)熱不(bu)合理(li)，也會加速(su)LED燈(deng)死燈(deng)。如果(guo)使(shi)用(yong)的環(huan)(huan)境(jing)很惡劣，導致LED燈(deng)具(ju)散(san)熱不(bu)良也會導致加速(su)燈(deng)具(ju)的故障率。

3、外部供電(dian)(dian)問題(ti)。LED抗浪涌(yong)的(de)(de)能(neng)力是比較差的(de)(de)，特別是抗反向電(dian)(dian)壓(ya)能(neng)力。如果外部供電(dian)(dian)電(dian)(dian)壓(ya)不穩定，經(jing)常出(chu)現高電(dian)(dian)壓(ya)的(de)(de)浪涌(yong)，也會導致LED燈具(ju)的(de)(de)故障(zhang)。
