led燈亮打火是怎么回事

這個問(wen)題，是(shi)電源內部電路(lu)有(you)自(zi)激(ji)，工(gong)作時(shi)，自(zi)激(ji)逐漸加強，到一定(ding)程度時(shi)電路(lu)發生阻(zu)塞，然后恢(hui)復(fu)初態。

這樣(yang)的過程周(zhou)而復始，形成(cheng)周(zhou)期性的亮度閃爍。具體(ti)如(ru)下：

（1）LED燈珠(zhu)(zhu)(zhu)與LED驅動(dong)電(dian)(dian)源不(bu)匹(pi)配,正常(chang)單顆足1W燈珠(zhu)(zhu)(zhu)承受電(dian)(dian)流:280-300mA,電(dian)(dian)壓:3.0-3.4V,如(ru)果燈珠(zhu)(zhu)(zhu)芯片不(bu)是足功率的就會造成燈光光源頻閃(shan)現(xian)象(xiang),電(dian)(dian)流過高燈珠(zhu)(zhu)(zhu)不(bu)能承受就一亮一滅,嚴重現(xian)象(xiang)會把燈珠(zhu)(zhu)(zhu)內(nei)置的金線或者(zhe)銅線燒斷,導致燈珠(zhu)(zhu)(zhu)不(bu)亮。

（2）可(ke)能是(shi)驅(qu)動(dong)電源壞了,只(zhi)要(yao)換上另一個(ge)好的驅(qu)動(dong)電源,就不閃了。

（3）如(ru)果(guo)驅(qu)動(dong)(dong)有(you)(you)過溫保(bao)護功能,而(er)燈具(ju)的材質散熱(re)(re)性(xing)能不能達到要求,驅(qu)動(dong)(dong)過溫保(bao)護開(kai)始工(gong)作也(ye)就會有(you)(you)一閃一滅的現(xian)象(xiang),例如(ru):20W投光(guang)燈外殼用來裝配30W的燈具(ju),散熱(re)(re)工(gong)作沒有(you)(you)做(zuo)好就會這樣了(le)。

（4）如果(guo)戶外燈(deng)(deng)具也有頻閃一亮(liang)一滅現象,那就(jiu)是(shi)(shi)燈(deng)(deng)具進水了。后果(guo)就(jiu)是(shi)(shi)閃著閃著就(jiu)不亮(liang)了。燈(deng)(deng)珠和驅動(dong)就(jiu)壞(huai)了,驅動(dong)防水做的好的話,就(jiu)只是(shi)(shi)壞(huai)掉燈(deng)(deng)珠,更換光源即可(ke)。

led燈接線后再接火線就打火

應(ying)該是led燈(deng)有燈(deng)珠短(duan)路了，檢(jian)查下(xia)燈(deng)珠好(hao)壞(huai)

led燈帶打火怎么回事

1、電線(xian)太(tai)細(xi)，線(xian)路超(chao)負(fu)荷

每(mei)平方的(de)電(dian)(dian)線(xian)(xian)(xian)(xian)都有(you)(you)其所(suo)(suo)能承(cheng)載(zai)的(de)安全(quan)載(zai)流(liu)(liu)量(liang)，如(ru)果通(tong)過(guo)電(dian)(dian)線(xian)(xian)(xian)(xian)的(de)電(dian)(dian)流(liu)(liu)超過(guo)它的(de)安全(quan)載(zai)流(liu)(liu)量(liang)，就會致(zhi)(zhi)使電(dian)(dian)線(xian)(xian)(xian)(xian)瞬(shun)間產(chan)生大(da)量(liang)熱量(liang),從(cong)而導(dao)致(zhi)(zhi)電(dian)(dian)線(xian)(xian)(xian)(xian)著(zhu)火，比如(ru)目前市場上的(de)LED燈(deng)箱卷簾(lian)燈(deng)所(suo)(suo)使用的(de)電(dian)(dian)源線(xian)(xian)(xian)(xian)大(da)部分都為0.75mm2;線(xian)(xian)(xian)(xian)，為了(le)導(dao)線(xian)(xian)(xian)(xian)能夠長時(shi)間連(lian)續的(de)運行，所(suo)(suo)能承(cheng)載(zai)的(de)電(dian)(dian)流(liu)(liu)為6A左右，24V的(de)功率為144W，卷簾(lian)燈(deng)條每(mei)米的(de)功率從(cong)6W到20W不(bu)等。而如(ru)果使用0.75mm2;線(xian)(xian)(xian)(xian)就需要頻繁接(jie)主線(xian)(xian)(xian)(xian)，一旦不(bu)接(jie)主線(xian)(xian)(xian)(xian)，電(dian)(dian)路過(guo)載(zai)，電(dian)(dian)線(xian)(xian)(xian)(xian)長時(shi)間有(you)(you)大(da)電(dian)(dian)流(liu)(liu)通(tong)過(guo)，就極易導(dao)致(zhi)(zhi)卷簾(lian)燈(deng)燒線(xian)(xian)(xian)(xian)、著(zhu)火，還有(you)(you)些工作人員由于(yu)對(dui)電(dian)(dian)線(xian)(xian)(xian)(xian)的(de)使用不(bu)了(le)解，主線(xian)(xian)(xian)(xian)都采用0.75mm2;線(xian)(xian)(xian)(xian)，導(dao)致(zhi)(zhi)LED燈(deng)箱在后期(qi)的(de)使用中存在極大(da)的(de)安全(quan)隱(yin)患。

2、線路短路引起的著火

線(xian)(xian)(xian)路(lu)(lu)(lu)(lu)短路(lu)(lu)(lu)(lu)也(ye)是(shi)引(yin)起LED燈(deng)箱卷簾(lian)燈(deng)著火(huo)的(de)主(zhu)要原因(yin)，線(xian)(xian)(xian)路(lu)(lu)(lu)(lu)短路(lu)(lu)(lu)(lu)主(zhu)要是(shi)因(yin)為輸電(dian)線(xian)(xian)(xian)路(lu)(lu)(lu)(lu)使(shi)用(yong)(yong)過久，絕(jue)緣層老化、破(po)裂，失去絕(jue)緣作用(yong)(yong)，導致(zhi)兩線(xian)(xian)(xian)相碰(peng);或者是(shi)由于亂拉(la)亂接(jie)電(dian)線(xian)(xian)(xian)，使(shi)電(dian)線(xian)(xian)(xian)的(de)"外套"機(ji)械損傷(shang)，引(yin)起短路(lu)(lu)(lu)(lu)。而采用(yong)(yong)的(de)電(dian)線(xian)(xian)(xian)如果較(jiao)細，頻(pin)繁(fan)接(jie)主(zhu)線(xian)(xian)(xian)，接(jie)線(xian)(xian)(xian)過程中電(dian)線(xian)(xian)(xian)纏(chan)繞(rao)在(zai)一起，長時間(jian)也(ye)可能(neng)會引(yin)起短路(lu)(lu)(lu)(lu)。所以在(zai)接(jie)線(xian)(xian)(xian)中一定要注意不能(neng)亂拉(la)、亂接(jie)、亂加(jia)用(yong)(yong)電(dian)裝(zhuang)置(zhi)，增(zeng)加(jia)LED燈(deng)箱整個線(xian)(xian)(xian)路(lu)(lu)(lu)(lu)的(de)用(yong)(yong)電(dian)負荷量。

3、采(cai)用劣質電(dian)線，質量(liang)不(bu)達標

正(zheng)規的(de)(de)企(qi)業生(sheng)產的(de)(de)國標線(xian)(xian)(xian)(xian)導(dao)(dao)線(xian)(xian)(xian)(xian)截(jie)面積(ji)是足量的(de)(de)，而那些(xie)非(fei)正(zheng)規企(qi)業生(sheng)產的(de)(de)國標線(xian)(xian)(xian)(xian)導(dao)(dao)線(xian)(xian)(xian)(xian)截(jie)面積(ji)往(wang)(wang)往(wang)(wang)不足，而LED燈(deng)箱使用這些(xie)偷工減料的(de)(de)劣(lie)質(zhi)導(dao)(dao)線(xian)(xian)(xian)(xian)(把導(dao)(dao)線(xian)(xian)(xian)(xian)拉的(de)(de)很細(xi)、使用劣(lie)質(zhi)二手銅(tong))就會(hui)引起(qi)絕緣(yuan)體斷(duan)裂，會(hui)造成短(duan)路、線(xian)(xian)(xian)(xian)路燒斷(duan)，甚至還會(hui)引起(qi)LED燈(deng)箱火災等嚴重后果。

LED燈冒電火不亮是怎么回事

LED的漏電(dian)流過(guo)大造(zao)成PN結失效，使(shi)LED燈(deng)點不亮(liang)(liang)。LED燈(deng)的內(nei)部連接(jie)引線斷開，造(zao)成LED無電(dian)流通過(guo)而產生不亮(liang)(liang)，也有可能LED燈(deng)工作電(dian)壓(ya)低。

LED燈(deng)(deng)其實就是(shi)一個(ge)發光二(er)極(ji)管，二(er)極(ji)管具有(you)單向導(dao)電(dian)性。用(yong)萬(wan)用(yong)表測(ce)量(liang)二(er)極(ji)管是(shi)否導(dao)通(tong)，測(ce)量(liang)出正負極(ji)，接(jie)入(ru)(ru)直(zhi)流(liu)電(dian)，正極(ji)接(jie)正極(ji)負極(ji)接(jie)負極(ji)，接(jie)入(ru)(ru)的直(zhi)流(liu)電(dian)伏數(shu)不(bu)能超出二(er)極(ji)管的耐壓值(zhi)，否則(ze)容易燒掉(diao)。這(zhe)是(shi)正確(que)的接(jie)法。如果連接(jie)后不(bu)亮，可(ke)能是(shi)LED燈(deng)(deng)壞掉(diao)，也(ye)可(ke)能是(shi)輸入(ru)(ru)電(dian)壓有(you)問題。

LED燈(deng)珠(zhu)是(shi)廣(guang)泛應用燈(deng)具的(de)照明，具有壽命長，功耗小，相比(bi)同等功率的(de)白熾燈(deng)和(he)熒光燈(deng)更加節能，亮度更高。其原理其實(shi)就(jiu)是(shi)同半導(dao)(dao)體二極(ji)管一樣，單(dan)向導(dao)(dao)通。如果燈(deng)珠(zhu)兩極(ji)電壓(ya)(ya)正常，燈(deng)珠(zhu)不亮首(shou)先要看一下電壓(ya)(ya)極(ji)性(xing)是(shi)否接(jie)反，其次用萬用表測(ce)量燈(deng)珠(zhu)兩端(duan)引腳是(shi)否正向導(dao)(dao)通，反向截止，基本上就(jiu)是(shi)這兩個(ge)方面的(de)問(wen)題。

電(dian)(dian)源是否正(zheng)(zheng)常(chang)是否是輸出直流電(dian)(dian)壓(ya)(ya)，電(dian)(dian)源電(dian)(dian)壓(ya)(ya)是否低于燈珠(zhu)的(de)工作電(dian)(dian)壓(ya)(ya)，電(dian)(dian)源輸出正(zheng)(zheng)負極是否與LED燈珠(zhu)正(zheng)(zheng)負極對應。

首先看燈珠是否是好(hao)的(de)，如果燈珠是好(hao)的(de)，看下電(dian)流夠(gou)(gou)不夠(gou)(gou)，電(dian)流不夠(gou)(gou)也不會(hui)亮(liang)的(de)
