怎么判斷LED燈珠的好壞

區分LED燈珠(zhu)的優劣(lie)方法：

一、看整體“燈(deng)具(ju)的(de)功率因數(shu)”：功率因數(shu)低，說明使(shi)用(yong)(yong)的(de)驅動電(dian)源、電(dian)路設計不好，會(hui)大大降低燈(deng)具(ju)的(de)使(shi)用(yong)(yong)壽命(ming)，功率因數(shu)低，使(shi)用(yong)(yong)再(zai)好燈(deng)珠(zhu)的(de)燈(deng)具(ju)壽命(ming)也不會(hui)長。

二(er)、看(kan)“燈(deng)(deng)具(ju)散熱條(tiao)件(jian)--材料、結構”：LED燈(deng)(deng)具(ju)散熱也是很(hen)重要的(de)，同樣功率因數(shu)的(de)燈(deng)(deng)具(ju)和(he)同品質的(de)燈(deng)(deng)珠(zhu)，如果(guo)散熱條(tiao)件(jian)不好，燈(deng)(deng)珠(zhu)在高溫(wen)下工(gong)作，光衰會(hui)很(hen)大，燈(deng)(deng)具(ju)壽(shou)命會(hui)減少。

三(san)、看“燈珠(zhu)品質(zhi)”：燈珠(zhu)品質(zhi)決定于芯(xin)片(pian)品質(zhi)和封(feng)裝技術。

四(si)、看燈(deng)具使(shi)(shi)用的(de)(de)(de)驅(qu)動電(dian)源，電(dian)源的(de)(de)(de)使(shi)(shi)用壽(shou)命(ming)(ming)相對燈(deng)具的(de)(de)(de)其他部分來說(shuo)，壽(shou)命(ming)(ming)要短很多(duo)，電(dian)源的(de)(de)(de)壽(shou)命(ming)(ming)影(ying)響燈(deng)具的(de)(de)(de)整體壽(shou)命(ming)(ming)，燈(deng)珠的(de)(de)(de)理論壽(shou)命(ming)(ming)在5-10萬小(xiao)時，而電(dian)源的(de)(de)(de)壽(shou)命(ming)(ming)在0.2-3萬小(xiao)時，電(dian)源的(de)(de)(de)設計與材料(liao)選擇會決定(ding)電(dian)源的(de)(de)(de)使(shi)(shi)用壽(shou)命(ming)(ming)。

五、看光(guang)(guang)效(xiao)：同樣(yang)的燈珠功率，光(guang)(guang)效(xiao)越高，亮(liang)度越高，同樣(yang)的照明亮(liang)度，耗電越小，越節能。

六、看電(dian)源效率，電(dian)源效率越(yue)(yue)高越(yue)(yue)好，越(yue)(yue)高，說(shuo)明(ming)電(dian)源本身的(de)功(gong)耗越(yue)(yue)小，輸(shu)出的(de)功(gong)率越(yue)(yue)大。

七、看是(shi)否符合(he)安全(quan)標準，我國LED燈具安全(quan)標準已經出臺，請按(an)國家規定(ding)的安全(quan)標準選擇LED燈具。

八(ba)、看(kan)做工是否精細(xi)。

一個(ge)品(pin)質好的(de)LED燈具，除上面提(ti)到的(de)幾個(ge)主要(yao)方面外，還要(yao)根(gen)據不(bu)同的(de)使用環境，有不(bu)同的(de)技術(shu)要(yao)求，如(ru)防潮、防塵、防磁、防雷(lei)擊等。--【OFweek半導體照明網(wang)】
