led照明燈的故障與維修

與以(yi)(yi)前的白熾(chi)燈(deng)不同，白熾(chi)燈(deng)壞(huai)了基本上都是(shi)鎢絲燒(shao)(shao)壞(huai)了，無法維修，只能(neng)更換。LED燈(deng)就不一樣了。LED燈(deng)由LED驅(qu)動電(dian)路和LED燈(deng)珠組成。大多數情況下，LED燈(deng)燒(shao)(shao)壞(huai)是(shi)可以(yi)(yi)修復的，下面(mian)就來聊一下led燈(deng)如(ru)果壞(huai)了如(ru)何修理常見故障是(shi)什(shen)么

1、LED燈珠損壞

這是一個很常(chang)見(jian)的故(gu)障，一般LED燈(deng)珠(zhu)燒壞(huai)(huai)時，表(biao)面會有黑(hei)點(dian)。仔細觀(guan)察就(jiu)能區(qu)分出來。對于這種故(gu)障的維護(hu)，需(xu)要配(pei)備(bei)烙鐵(tie)，拆下燒壞(huai)(huai)的燈(deng)珠(zhu)更換。

沒有LED燈珠怎么辦可以(yi)用150ω左右的電(dian)阻代替，恒流源驅(qu)動可以(yi)直(zhi)接(jie)短接(jie)。

2、濾波電容失效

簡易(yi)LED燈一般通過(guo)容(rong)阻降(jiang)壓直(zhi)接整流(liu)交流(liu)電(dian)，然(ran)后(hou)通過(guo)電(dian)容(rong)濾波(bo)(bo)給LED燈珠供電(dian)。如果濾波(bo)(bo)電(dian)容(rong)失效，會導致電(dian)壓不穩(wen)定，DC電(dian)壓低(di)，使LED燈變暗。

用萬用表的(de)電(dian)容檔測量(liang)濾波電(dian)容的(de)容量(liang)。如果誤差較大(da)，誤差大(da)于30%，說(shuo)明電(dian)容已經變質可以更換耐(nai)壓值和容量(liang)大(da)于等(deng)于電(dian)容參數的(de)電(dian)容。

3、容阻降(jiang)壓模塊損壞

容(rong)阻(zu)降壓模塊由電(dian)容(rong)電(dian)容(rong)和(he)電(dian)阻(zu)并聯組(zu)成。萬用(yong)表可(ke)以(yi)用(yong)來測量(liang)電(dian)容(rong)電(dian)阻(zu)是否損(sun)壞(huai)。如果損(sun)壞(huai)，可(ke)以(yi)更換參數相當(dang)的電(dian)容(rong)電(dian)阻(zu)。

4、線路斷開

打開(kai)LED燈，檢查內部輸(shu)入輸(shu)出(chu)接(jie)線是否斷開(kai)。如果是，用烙鐵焊接(jie)固定。

5、整流二極管故障

整流(liu)二極管有開路(lu)、短路(lu)等故(gu)障，可能是過(guo)(guo)壓過(guo)(guo)流(liu)或(huo)長(chang)期使用故(gu)障造成的。找一個反向(xiang)耐壓值大于350V、工作電流(liu)大于0.5A的整流(liu)二極管，比(bi)如1N4004~1N4007。

6、LED恒流驅動(dong)電路故障

對于(yu)(yu)這種故(gu)障(zhang)(zhang)，需要有一定電子相關經驗的(de)專業(ye)人員來維護。對于(yu)(yu)普通用戶來說，在找不(bu)到上述(shu)簡單故(gu)障(zhang)(zhang)的(de)原因后，更換新的(de)LED燈。

led燈怎樣查哪個燈珠壞了

1.

可以將led燈(deng)帶通上(shang)電(dian)(dian)之后(hou)，使用(yong)萬用(yong)表(biao)的電(dian)(dian)壓檔在led燈(deng)串的兩端，檢查(cha)是否有電(dian)(dian)壓輸出，就可以確定led燈(deng)的燈(deng)珠是否出現故障。

2.

Led燈珠(zhu)不發(fa)光，那么就(jiu)(jiu)代表(biao)燈珠(zhu)是(shi)處(chu)于故障狀態，使用(yong)(yong)(yong)(yong)相(xiang)同功率的(de)(de)燈珠(zhu)進行替換即可。方(fang)(fang)法(fa)1：用(yong)(yong)(yong)(yong)萬(wan)用(yong)(yong)(yong)(yong)表(biao)的(de)(de)二(er)(er)極管(guan)測試檔，測試每個(ge)(ge)LED二(er)(er)極管(guan)（正向(xiang)，LED點亮(liang)。反(fan)向(xiang)，不亮(liang)）方(fang)(fang)法(fa)2：大多數LED燈內部就(jiu)(jiu)是(shi)一個(ge)(ge)可充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池，由此(ci)電(dian)(dian)(dian)池給LED燈供電(dian)(dian)(dian)，可用(yong)(yong)(yong)(yong)萬(wan)用(yong)(yong)(yong)(yong)表(biao)測量一下(xia)這個(ge)(ge)電(dian)(dian)(dian)池（一般是(shi)4~6V）。就(jiu)(jiu)可確定壞的(de)(de)地(di)方(fang)(fang)。方(fang)(fang)法(fa)3：沒(mei)(mei)有萬(wan)用(yong)(yong)(yong)(yong)表(biao)時，拔下(xia)LED燈電(dian)(dian)(dian)源(yuan)線用(yong)(yong)(yong)(yong)剪子剪斷電(dian)(dian)(dian)池線接(jie)上(shang)別的(de)(de)用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)器(qi)，如果實在(zai)沒(mei)(mei)有別的(de)(de)用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)器(qi)，就(jiu)(jiu)用(yong)(yong)(yong)(yong)其中(zhong)的(de)(de)一根電(dian)(dian)(dian)池線快(kuai)速觸碰另一個(ge)(ge)極，看(kan)看(kan)有沒(mei)(mei)有火星或啪的(de)(de)一聲響。若有，證明是(shi)LED燈壞了(le)。特(te)別提醒一下(xia)，注(zhu)意安全一定要(yao)拔下(xia)LED燈電(dian)(dian)(dian)源(yuan)線后，使用(yong)(yong)(yong)(yong)此(ci)方(fang)(fang)法(fa)。，

led燈故障與維修

1、LED燈常(chang)見故障及(ji)維修方法

2、1.LED燈(deng)珠(zhu)(zhu)損(sun)壞。這(zhe)是一(yi)個很常見的(de)錯誤(wu)。一(yi)般LED燈(deng)珠(zhu)(zhu)燒壞時，表面會有黑點，仔(zi)細(xi)觀察就能分辨出來。對于(yu)這(zhe)種(zhong)故障(zhang)維修，需要配備烙鐵來清除燒壞的(de)燈(deng)珠(zhu)(zhu)并更換。沒有LED燈(deng)珠(zhu)(zhu)怎(zen)么辦它可以由(you)一(yi)個約150的(de)電(dian)阻(zu)代替(ti)，如(ru)果由(you)恒流(liu)源(yuan)驅(qu)動，該電(dian)阻(zu)可以直接(jie)短路(lu)。

3、2.濾波電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)失效。簡(jian)單的LED燈(deng)(deng)(deng)通(tong)常是通(tong)過電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)電(dian)(dian)阻(zu)降壓(ya)(ya)后(hou)直接對交流(liu)電(dian)(dian)源進(jin)行整(zheng)流(liu)，再通(tong)過電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)濾波給LED燈(deng)(deng)(deng)珠供電(dian)(dian)。如果濾波電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)失效，電(dian)(dian)壓(ya)(ya)會(hui)不穩定(ding)，DC電(dian)(dian)壓(ya)(ya)會(hui)很低，會(hui)使LED燈(deng)(deng)(deng)變(bian)暗。用萬用表的電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)文(wen)件測量濾波電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)的容(rong)(rong)(rong)(rong)(rong)(rong)量。如果誤差(cha)大于(yu)30%，則意味著電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)已經退化(hua)。只(zhi)需找(zhao)一個(ge)耐(nai)壓(ya)(ya)和容(rong)(rong)(rong)(rong)(rong)(rong)量大于(yu)等(deng)于(yu)電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)參數的電(dian)(dian)容(rong)(rong)(rong)(rong)(rong)(rong)，更換即可。

4、3.電(dian)(dian)容(rong)(rong)電(dian)(dian)阻降壓(ya)模(mo)塊(kuai)損(sun)壞。電(dian)(dian)容(rong)(rong)電(dian)(dian)阻降壓(ya)模(mo)塊(kuai)由并聯的電(dian)(dian)容(rong)(rong)和(he)電(dian)(dian)阻組成。萬用(yong)表可以用(yong)來測量電(dian)(dian)容(rong)(rong)器(qi)和(he)電(dian)(dian)阻器(qi)是(shi)否損(sun)壞。如果(guo)損(sun)壞，找一個等效參(can)數的電(dian)(dian)容(rong)(rong)和(he)電(dian)(dian)阻來更換(huan)。

5、4.線路斷開了。拆開LED燈，檢查內(nei)部輸入輸出接線有無斷線，如果有，用電烙鐵(tie)焊接固定。

6、5.整(zheng)(zheng)流(liu)(liu)二極管故(gu)(gu)(gu)障。整(zheng)(zheng)流(liu)(liu)二極管有(you)開(kai)路、短路等故(gu)(gu)(gu)障，可(ke)能(neng)是過電(dian)(dian)壓(ya)、過電(dian)(dian)流(liu)(liu)引起(qi)的(de)，也可(ke)能(neng)是長期(qi)使(shi)用故(gu)(gu)(gu)障引起(qi)的(de)。隨便找一個反向耐壓(ya)大(da)于350V，工(gong)作(zuo)電(dian)(dian)流(liu)(liu)大(da)于0.5A的(de)整(zheng)(zheng)流(liu)(liu)二極管，比如1N4004~1N4007等。

7、6.LED恒(heng)流驅動電(dian)路故障。對于(yu)這種故障，需要有一(yi)定電(dian)子經驗(yan)的專業(ye)人(ren)員進行(xing)維修。對于(yu)普通用戶(hu)來說，在以上簡單故障查不出來后，不如更換(huan)一(yi)個(ge)新的LED燈。

8、以上是關于LED燈常見故障及維修(xiu)方法的(de)知識。希望你能有所收獲。

led燈壞了如何排查怎么修

1、LED燈珠(zhu)損壞(huai)。這是很常見的故障(zhang)，一(yi)般LED燈珠(zhu)燒(shao)壞(huai)時，表面上(shang)會有黑點，仔(zi)細觀察能(neng)夠區分出來(lai)，對(dui)于這種故障(zhang)維修(xiu)，需要(yao)配備(bei)一(yi)把烙鐵，將燒(shao)壞(huai)的燈珠(zhu)拆下來(lai)更換即可，若(ruo)(ruo)沒有LED燈珠(zhu)怎么辦可使用150Ω左(zuo)右的電阻代替，若(ruo)(ruo)是恒流源驅動(dong)可以直(zhi)接(jie)短接(jie)。

2、濾(lv)波電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)失效。簡(jian)易的(de)LED燈(deng)一(yi)般將交流(liu)電(dian)(dian)(dian)(dian)(dian)經過容(rong)(rong)(rong)(rong)阻降壓后直接(jie)整流(liu)，然后通過電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)濾(lv)波給(gei)LED燈(deng)珠供電(dian)(dian)(dian)(dian)(dian)。若該(gai)濾(lv)波電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)失效會導致(zhi)電(dian)(dian)(dian)(dian)(dian)壓不(bu)穩，直流(liu)電(dian)(dian)(dian)(dian)(dian)壓偏低，從而使(shi)LED燈(deng)變暗(an)。用萬用表的(de)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)檔(dang)測量(liang)(liang)該(gai)濾(lv)波電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)的(de)容(rong)(rong)(rong)(rong)量(liang)(liang)，若誤(wu)差(cha)較大(da)，誤(wu)差(cha)大(da)于30%左右(you)說明該(gai)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)已變質，找一(yi)個耐壓值以及容(rong)(rong)(rong)(rong)量(liang)(liang)都(dou)大(da)于等(deng)于該(gai)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)參(can)數的(de)電(dian)(dian)(dian)(dian)(dian)容(rong)(rong)(rong)(rong)換(huan)上即可(ke)。

led燈棒如何判斷哪個壞了

一、怎(zen)樣檢測(ce)led燈珠壞(huai)了(le)

1、可以將(jiang)led燈帶通(tong)上電之后使用萬用表的電壓檔在led燈串的兩端檢查是否有電壓輸(shu)出就可以確定led燈的燈珠是否出現故障(zhang)。

2、 Led燈(deng)珠不發光，那么就代表燈(deng)珠是(shi)處于(yu)故障狀態，這也(ye)是(shi)可以直接判(pan)斷出燈(deng)珠是(shi)否(fou)損(sun)壞的(de)(de)一個(ge)辦法(fa)，若檢(jian)測(ce)到燈(deng)珠損(sun)壞后，也(ye)是(shi)需要使用相同功率的(de)(de)燈(deng)珠進行替換(huan)即可維修好。

二、Led燈有哪些優勢(shi)

1、Led燈是(shi)屬(shu)于(yu)一種(zhong)高效節能的產(chan)品(pin)(pin)，這種(zhong)產(chan)品(pin)(pin)所涉及的領域(yu)也(ye)是(shi)很廣(guang)泛的，不僅可以用于(yu)日常家電使用，同時(shi)在機械生產(chan)方面也(ye)是(shi)被(bei)廣(guang)泛使用的。

2、Led燈在出現故障之(zhi)后維修辦法也相對較簡(jian)單一(yi)些，其功(gong)率也有大(da)小(xiao)之(zhi)分，我們(men)可以(yi)結合實際使用的(de)范圍以(yi)及不同的(de)領域去(qu)判斷購買多大(da)功(gong)率的(de)led燈。

三、Led燈帶可以用于(yu)哪(na)些(xie)裝飾

1、Led燈帶(dai)可(ke)(ke)以(yi)(yi)用(yong)于(yu)(yu)(yu)房間(jian)裝飾(shi)，也可(ke)(ke)用(yong)于(yu)(yu)(yu)在布置(zhi)驚(jing)喜時去使用(yong)，它可(ke)(ke)以(yi)(yi)起(qi)到很(hen)好的裝飾(shi)效果，并(bing)且也可(ke)(ke)以(yi)(yi)起(qi)到一(yi)定的照明作用(yong)，對于(yu)(yu)(yu)裝飾(shi)要(yao)求比(bi)較高的朋友來說，可(ke)(ke)以(yi)(yi)將(jiang)LED燈帶(dai)布置(zhi)成我們喜愛(ai)的形狀即可(ke)(ke)達成一(yi)個(ge)比(bi)較好的裝飾(shi)作用(yong)。

2、Led燈(deng)帶在使(shi)用期間也(ye)一(yi)定不能連(lian)續(xu)工(gong)作很長(chang)時間，長(chang)時間使(shi)用的(de)燈(deng)帶會加速led燈(deng)帶的(de)使(shi)用壽命，甚(shen)至也(ye)會導(dao)致 Led燈(deng)帶在使(shi)用過程當中出現短路的(de)這種問題(ti)。
