led燈燒燈珠什么原因

原(yuan)因:散熱不好就容易(yi)燒壞(huai)

LED燈(deng)與(yu)驅(qu)動(dong)(dong)器是配套(tao)使用的，驅(qu)動(dong)(dong)器直流(liu)輸出的電(dian)(dian)(dian)(dian)(dian)壓和電(dian)(dian)(dian)(dian)(dian)流(liu)與(yu)燈(deng)板需要的電(dian)(dian)(dian)(dian)(dian)壓和電(dian)(dian)(dian)(dian)(dian)流(liu)一致。LED燈(deng)珠(zhu)發光(guang)亮度(du)對(dui)電(dian)(dian)(dian)(dian)(dian)流(liu)很敏感(gan)，燈(deng)珠(zhu)通過的電(dian)(dian)(dian)(dian)(dian)流(liu)也(ye)有極限值。電(dian)(dian)(dian)(dian)(dian)流(liu)大時亮度(du)大但也(ye)發熱大，散熱不好就(jiu)容易燒壞。一般講(jiang)因(yin)驅(qu)動(dong)(dong)器電(dian)(dian)(dian)(dian)(dian)壓波(bo)動(dong)(dong)升高點而(er)擊穿(chuan)燈(deng)珠(zhu)的很少，但因(yin)電(dian)(dian)(dian)(dian)(dian)流(liu)波(bo)動(dong)(dong)加大燒壞燈(deng)珠(zhu)的多(duo)。可在驅(qu)動(dong)(dong)器輸出端串一小電(dian)(dian)(dian)(dian)(dian)阻限流(liu)保護燈(deng)珠(zhu)(亮度(du)稍減)。

led燈珠經常燒是怎么回事

可能是驅動電(dian)源不好(hao)(hao),電(dian)流較大,LED燈珠散熱不好(hao)(hao),廠(chang)家為了降低成本,采用質量差(cha)得(de)燈珠,所以經常會燒壞(huai)。

LED燈珠燒壞是什么情況

一般來說電(dian)(dian)壓過高的情況下燈(deng)珠(zhu)容(rong)易(yi)燒(shao)壞(huai)，led燈(deng)珠(zhu)實際上(shang)就是(shi)(shi)發光二(er)極管，根據二(er)極管的伏安特(te)性曲線可知它(ta)對電(dian)(dian)壓是(shi)(shi)比較(jiao)敏感的，特(te)別是(shi)(shi)在額定(ding)電(dian)(dian)壓附近，每當(dang)電(dian)(dian)壓增大(da)一點點通過燈(deng)珠(zhu)的電(dian)(dian)流就會增大(da)很多倍，因(yin)此如果燈(deng)珠(zhu)兩(liang)端的電(dian)(dian)壓波動比較(jiao)大(da)，超過了燈(deng)珠(zhu)的額定(ding)電(dian)(dian)壓時燈(deng)珠(zhu)就容(rong)易(yi)燒(shao)壞(huai)。

led燈珠總是燒是什么原因

led燈(deng)珠接在車上老(lao)是(shi)燒(shao)，是(shi)因為電(dian)(dian)壓(ya)高了，LED的工作電(dian)(dian)壓(ya)為3V左右(you)。應給LED燈(deng)珠串(chuan)接一個適當的電(dian)(dian)阻進行(xing)降壓(ya)，選擇(ze)大多的電(dian)(dian)阻，需要根(gen)據電(dian)(dian)壓(ya)及LED燈(deng)珠的個數來定。

LED：發(fa)光二極(ji)管簡稱為(wei)LED。由含鎵（Ga）、砷（As）、磷（P）、氮（N）等(deng)的化(hua)合物制成。

當電子與空穴復合時能(neng)輻射出可(ke)見光(guang)(guang)，因而可(ke)以用來(lai)制成發(fa)光(guang)(guang)二極管(guan)。在電路及儀(yi)器中(zhong)作為指示(shi)燈，或(huo)者組成文字(zi)或(huo)數字(zi)顯示(shi)。砷(shen)化鎵(jia)二極管(guan)發(fa)紅(hong)光(guang)(guang)，磷化鎵(jia)二極管(guan)發(fa)綠光(guang)(guang)，碳化硅二極管(guan)發(fa)黃光(guang)(guang)，氮化鎵(jia)二極管(guan)發(fa)藍光(guang)(guang)。因化學性質(zhi)又分有機(ji)發(fa)光(guang)(guang)二極管(guan)OLED和無機(ji)發(fa)光(guang)(guang)二極管(guan)LED。
