led燈壞了如何排查怎么修

1、LED燈(deng)(deng)珠損(sun)壞(huai)。這是(shi)很常見的故障，一(yi)般LED燈(deng)(deng)珠燒(shao)壞(huai)時，表面(mian)上會有黑(hei)點，仔細觀(guan)察能(neng)夠區分出(chu)來(lai)，對(dui)于這種故障維(wei)修，需要配備(bei)一(yi)把烙鐵，將燒(shao)壞(huai)的燈(deng)(deng)珠拆下來(lai)更換(huan)即可(ke)，若沒有LED燈(deng)(deng)珠怎(zen)么辦可(ke)使(shi)用150Ω左右的電阻(zu)代(dai)替，若是(shi)恒流源(yuan)驅動可(ke)以直(zhi)接短(duan)接。

2、濾(lv)(lv)波電(dian)容(rong)(rong)失效。簡易(yi)的(de)(de)LED燈一般(ban)將交流電(dian)經過(guo)(guo)容(rong)(rong)阻(zu)降壓(ya)(ya)后直接(jie)整流，然后通(tong)過(guo)(guo)電(dian)容(rong)(rong)濾(lv)(lv)波給LED燈珠(zhu)供電(dian)。若該(gai)濾(lv)(lv)波電(dian)容(rong)(rong)失效會導(dao)致電(dian)壓(ya)(ya)不穩，直流電(dian)壓(ya)(ya)偏低，從而(er)使LED燈變暗。用萬(wan)用表的(de)(de)電(dian)容(rong)(rong)檔測量該(gai)濾(lv)(lv)波電(dian)容(rong)(rong)的(de)(de)容(rong)(rong)量，若誤差較大，誤差大于(yu)(yu)30%左右說明該(gai)電(dian)容(rong)(rong)已變質，找(zhao)一個耐壓(ya)(ya)值以(yi)及容(rong)(rong)量都大于(yu)(yu)等于(yu)(yu)該(gai)電(dian)容(rong)(rong)參(can)數的(de)(de)電(dian)容(rong)(rong)換上即可。

led并聯燈珠燒壞一組怎樣修復

可(ke)以直接把損(sun)壞(huai)的那段(duan)剪掉，重(zhong)新(xin)焊(han)接新(xin)的，重(zhong)新(xin)焊(han)接即可(ke)。但是(shi)話又說回來(lai)，每條LED燈(deng)條上有(you)很多LED貼片燈(deng)元件，壞(huai)一二個，對亮度沒什么影響。

關于(yu)LED燈(deng)(deng)珠壞(huai)了怎么辦這個問題，我們要(yao)(yao)根據是(shi)什(shen)么情況來做相對(dui)(dui)應的措施，無論是(shi)LED損壞(huai)還是(shi)驅動電源損壞(huai)，為了安(an)全起見，建(jian)議去找專業人員進行(xing)修理，在(zai)使(shi)用(yong)時不僅要(yao)(yao)考慮LED本身所發出來的熱量對(dui)(dui)燈(deng)(deng)的影響，還要(yao)(yao)考慮周圍(wei)環境溫度對(dui)(dui)燈(deng)(deng)的光電性能影響

客廳的LED燈珠經常被燒壞該怎么修理電路需串聯一個多大的電阻

提問者說，客廳里的LED燈(deng)的燈(deng)珠(zhu)(zhu)經常被(bei)燒(shao)壞，出現(xian)這(zhe)種情(qing)況一般是LED燈(deng)珠(zhu)(zhu)的驅動(dong)電流偏(pian)大，再加上燈(deng)珠(zhu)(zhu)可(ke)能散(san)熱不好，這(zhe)樣(yang)便會導致燈(deng)珠(zhu)(zhu)燒(shao)壞。 簡(jian)單的阻容(rong)降(jiang)壓恒流驅動(dong)電路。

現在(zai)的LED燈質量好的其(qi)恒(heng)(heng)流(liu)(liu)(liu)(liu)(liu)驅(qu)(qu)動(dong)(dong)器一般都采(cai)用專(zhuan)用的恒(heng)(heng)流(liu)(liu)(liu)(liu)(liu)驅(qu)(qu)動(dong)(dong)IC設(she)計(ji)，驅(qu)(qu)動(dong)(dong)電(dian)(dian)流(liu)(liu)(liu)(liu)(liu)比(bi)較(jiao)穩定(ding)，一般不(bu)(bu)(bu)容(rong)易損壞(huai)，而(er)一些(xie)廉價的LED燈有(you)不(bu)(bu)(bu)少都是采(cai)用上(shang)圖所示的簡(jian)單的阻容(rong)降壓(ya)恒(heng)(heng)流(liu)(liu)(liu)(liu)(liu)驅(qu)(qu)動(dong)(dong)電(dian)(dian)路。這種(zhong)驅(qu)(qu)動(dong)(dong)電(dian)(dian)路的驅(qu)(qu)動(dong)(dong)電(dian)(dian)流(liu)(liu)(liu)(liu)(liu)不(bu)(bu)(bu)太穩定(ding)，其(qi)大(da)(da)小與電(dian)(dian)容(rong)C1的容(rong)量、市電(dian)(dian)電(dian)(dian)壓(ya)的高(gao)低(di)有(you)關。若遇到市電(dian)(dian)電(dian)(dian)壓(ya)偏(pian)高(gao)，或C1取值偏(pian)大(da)(da)，這樣便(bian)會(hui)導致流(liu)(liu)(liu)(liu)(liu)過燈珠的電(dian)(dian)流(liu)(liu)(liu)(liu)(liu)變大(da)(da)，而(er)LED燈珠在(zai)燈罩內，若燈珠的散熱不(bu)(bu)(bu)好，工作時間一長便(bian)可能會(hui)被燒壞(huai)。 簡(jian)單的LED恒(heng)(heng)流(liu)(liu)(liu)(liu)(liu)驅(qu)(qu)動(dong)(dong)電(dian)(dian)路板(ban)。

出現(xian)這種情(qing)況(kuang)，我(wo)們可(ke)(ke)以(yi)用萬用表測量(liang)一(yi)下市電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)是否(fou)偏(pian)高，降(jiang)壓(ya)電(dian)(dian)(dian)容(rong)(rong)的(de)(de)容(rong)(rong)量(liang)與燈(deng)珠(zhu)的(de)(de)工作(zuo)電(dian)(dian)(dian)流(liu)(liu)是否(fou)匹配。若所(suo)在(zai)(zai)地區的(de)(de)市電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)經常偏(pian)高，可(ke)(ke)以(yi)將電(dian)(dian)(dian)容(rong)(rong)C1的(de)(de)容(rong)(rong)量(liang)適(shi)當減小一(yi)些。為了防止開燈(deng)瞬間浪涌電(dian)(dian)(dian)流(liu)(liu)損壞(huai)燈(deng)珠(zhu)，亦可(ke)(ke)以(yi)適(shi)當增(zeng)大(da)電(dian)(dian)(dian)容(rong)(rong)C2的(de)(de)容(rong)(rong)量(liang)。另外，若C1找不到合適(shi)容(rong)(rong)量(liang)的(de)(de)電(dian)(dian)(dian)容(rong)(rong)，亦可(ke)(ke)以(yi)在(zai)(zai)C2兩端并聯一(yi)個阻(zu)(zu)值及功率合適(shi)的(de)(de)電(dian)(dian)(dian)阻(zu)(zu)（具體阻(zu)(zu)值視(shi)實際情(qing)況(kuang)而定），這樣可(ke)(ke)以(yi)對(dui)流(liu)(liu)入LED燈(deng)珠(zhu)的(de)(de)電(dian)(dian)(dian)流(liu)(liu)進行分流(liu)(liu)，從而減小燈(deng)珠(zhu)的(de)(de)工作(zuo)電(dian)(dian)(dian)流(liu)(liu)，降(jiang)低其(qi)發熱量(liang)。

若(ruo)想了(le)解更(geng)多的(de)電子電路(lu)及(ji)元器(qi)件知識，請(qing)關注我，謝謝。

LED燈一閃就不亮了這該怎么維修

LED燈(deng)(deng)由恒(heng)流(liu)驅(qu)動(dong)電(dian)路(lu)和燈(deng)(deng)珠兩部分組成，這種燈(deng)(deng)常見的故障就是(shi)燈(deng)(deng)珠損壞和電(dian)源濾波電(dian)容(rong)損壞（恒(heng)流(liu)驅(qu)動(dong)電(dian)路(lu)中(zhong)的恒(heng)流(liu)IC很(hen)少損壞），若(ruo)提問(wen)者懂電(dian)子(zi)技(ji)術，可(ke)以(yi)自己動(dong)手修理。

一、LED燈珠損(sun)壞(huai) 損(sun)壞(huai)的(de)LED燈珠有黑點。

LED燈(deng)(deng)(deng)泡一(yi)般密封較嚴，燈(deng)(deng)(deng)珠(zhu)(zhu)在密閉空間里(li)長時間工(gong)作(zuo)，若燈(deng)(deng)(deng)珠(zhu)(zhu)的(de)工(gong)作(zuo)電(dian)流(liu)較大(da)，并且散熱(re)不好，燈(deng)(deng)(deng)珠(zhu)(zhu)容易因過(guo)熱(re)而損壞(huai)(huai)。有些(xie)燈(deng)(deng)(deng)珠(zhu)(zhu)處于(yu)臨界損壞(huai)(huai)狀態，接通電(dian)源(yuan)瞬間可能因電(dian)流(liu)的(de)沖擊，閃(shan)一(yi)下就壞(huai)(huai)了，由于(yu)LED燈(deng)(deng)(deng)珠(zhu)(zhu)一(yi)般為多個(ge)燈(deng)(deng)(deng)珠(zhu)(zhu)串(chuan)聯(lian)，這樣損壞(huai)(huai)一(yi)個(ge)，就會導致整串(chuan)燈(deng)(deng)(deng)珠(zhu)(zhu)不亮。

一般燒壞(huai)的(de)(de)(de)LED燈(deng)珠上面有黑點（見(jian)上圖(tu)），若(ruo)手里有相同規(gui)格的(de)(de)(de)燈(deng)珠，可以將壞(huai)的(de)(de)(de)燈(deng)珠拆下，換(huan)個新的(de)(de)(de)即可。若(ruo)沒有燈(deng)珠，亦(yi)可以選(xuan)用一個十幾Ω以下的(de)(de)(de)小電阻焊接在(zai)原來燈(deng)珠的(de)(de)(de)位置。

二、恒(heng)流驅(qu)動電路的故(gu)障 LED恒(heng)流驅(qu)動器(qi)。

現在(zai)的(de)(de)LED燈(deng)(deng)泡一般(ban)都采用專用的(de)(de)恒流(liu)(liu)(liu)IC構成恒流(liu)(liu)(liu)驅動電(dian)(dian)(dian)(dian)路。這(zhe)類恒流(liu)(liu)(liu)驅動電(dian)(dian)(dian)(dian)路中的(de)(de)恒流(liu)(liu)(liu)IC、電(dian)(dian)(dian)(dian)感線圈及整(zheng)流(liu)(liu)(liu)管(guan)一般(ban)很少損(sun)壞(huai)，容(rong)(rong)易(yi)損(sun)壞(huai)的(de)(de)元(yuan)件就(jiu)是(shi)那個高(gao)壓濾(lv)波(bo)電(dian)(dian)(dian)(dian)容(rong)(rong)。這(zhe)類電(dian)(dian)(dian)(dian)容(rong)(rong)皆為電(dian)(dian)(dian)(dian)解(jie)電(dian)(dian)(dian)(dian)容(rong)(rong)，有些燈(deng)(deng)泡濾(lv)波(bo)電(dian)(dian)(dian)(dian)容(rong)(rong)的(de)(de)耐壓值(zhi)選的(de)(de)較(jiao)低，若交(jiao)流(liu)(liu)(liu)220V電(dian)(dian)(dian)(dian)壓偏高(gao)，可(ke)能會導致(zhi)該(gai)電(dian)(dian)(dian)(dian)容(rong)(rong)擊穿損(sun)壞(huai)，這(zhe)樣恒流(liu)(liu)(liu)驅動電(dian)(dian)(dian)(dian)路無法正常工作，燈(deng)(deng)也就(jiu)不會點亮(liang)了(le)。遇到電(dian)(dian)(dian)(dian)源濾(lv)波(bo)電(dian)(dian)(dian)(dian)容(rong)(rong)損(sun)壞(huai)，可(ke)以選用相同容(rong)(rong)量，耐壓值(zhi)不低于(yu)原(yuan)電(dian)(dian)(dian)(dian)容(rong)(rong)的(de)(de)電(dian)(dian)(dian)(dian)解(jie)電(dian)(dian)(dian)(dian)容(rong)(rong)代換。

若想(xiang)了解(jie)更多的電子電路及(ji)元器件知識，請關(guan)注我，謝謝。

led燈故障與維修

1、LED燈常見故障及維修方法

2、1.LED燈(deng)珠(zhu)損壞。這(zhe)是一個很常見的(de)(de)(de)錯誤(wu)。一般LED燈(deng)珠(zhu)燒壞時，表(biao)面會有黑點，仔細觀察就能分辨出來(lai)。對于這(zhe)種故(gu)障維修，需要配備(bei)烙鐵來(lai)清除燒壞的(de)(de)(de)燈(deng)珠(zhu)并更換。沒(mei)有LED燈(deng)珠(zhu)怎(zen)么(me)辦它可以由(you)一個約150的(de)(de)(de)電阻代替，如果由(you)恒流源驅(qu)動，該電阻可以直接短路。

3、2.濾波電(dian)容(rong)(rong)(rong)失效。簡單的(de)(de)LED燈通(tong)常是通(tong)過(guo)電(dian)容(rong)(rong)(rong)電(dian)阻降壓(ya)(ya)(ya)后直接對交流電(dian)源進行(xing)整流，再通(tong)過(guo)電(dian)容(rong)(rong)(rong)濾波給LED燈珠供電(dian)。如(ru)果(guo)濾波電(dian)容(rong)(rong)(rong)失效，電(dian)壓(ya)(ya)(ya)會(hui)不穩定，DC電(dian)壓(ya)(ya)(ya)會(hui)很低，會(hui)使LED燈變(bian)暗。用萬用表的(de)(de)電(dian)容(rong)(rong)(rong)文件測量濾波電(dian)容(rong)(rong)(rong)的(de)(de)容(rong)(rong)(rong)量。如(ru)果(guo)誤差(cha)大(da)于(yu)30%，則意味著(zhu)電(dian)容(rong)(rong)(rong)已經退化。只(zhi)需找一個耐壓(ya)(ya)(ya)和容(rong)(rong)(rong)量大(da)于(yu)等于(yu)電(dian)容(rong)(rong)(rong)參(can)數的(de)(de)電(dian)容(rong)(rong)(rong)，更換(huan)即可(ke)。

4、3.電(dian)(dian)(dian)(dian)容(rong)(rong)電(dian)(dian)(dian)(dian)阻(zu)降壓(ya)模塊(kuai)損壞。電(dian)(dian)(dian)(dian)容(rong)(rong)電(dian)(dian)(dian)(dian)阻(zu)降壓(ya)模塊(kuai)由并聯的電(dian)(dian)(dian)(dian)容(rong)(rong)和電(dian)(dian)(dian)(dian)阻(zu)組成。萬用(yong)表可以用(yong)來測(ce)量(liang)電(dian)(dian)(dian)(dian)容(rong)(rong)器和電(dian)(dian)(dian)(dian)阻(zu)器是否損壞。如果損壞，找一個(ge)等效參(can)數的電(dian)(dian)(dian)(dian)容(rong)(rong)和電(dian)(dian)(dian)(dian)阻(zu)來更換。

5、4.線路斷開了。拆開LED燈，檢查內部輸入(ru)輸出(chu)接線有(you)無斷線，如果有(you)，用(yong)電烙鐵焊(han)接固定。

6、5.整流二極(ji)管(guan)(guan)故障(zhang)。整流二極(ji)管(guan)(guan)有開路(lu)、短路(lu)等(deng)(deng)故障(zhang)，可能是(shi)過(guo)電(dian)壓、過(guo)電(dian)流引起的(de)(de)，也可能是(shi)長期(qi)使(shi)用故障(zhang)引起的(de)(de)。隨便找(zhao)一(yi)個反向耐(nai)壓大于(yu)350V，工作(zuo)電(dian)流大于(yu)0.5A的(de)(de)整流二極(ji)管(guan)(guan)，比如1N4004~1N4007等(deng)(deng)。

7、6.LED恒流驅動電(dian)路(lu)故障。對于這種故障，需要有一定電(dian)子經(jing)驗的專業人員進行維修。對于普通(tong)用戶來說，在以上簡(jian)單故障查不出來后，不如更(geng)換一個(ge)新的LED燈(deng)。

8、以(yi)上是關于(yu)LED燈常見故障及(ji)維修方法的(de)知識。希望你能有所收獲。
