大(da)家好今天來介紹(shao) 燈(deng)珠(zhu)和cob的區(qu)別的問題，以下(xia)是小(xiao)編對(dui)此問題的歸納(na)整(zheng)理(li)，來看看吧。

什么是COB燈珠？

COB光(guang)(guang)源是(shi)在LED芯片直接貼在高(gao)(gao)反(fan)光(guang)(guang)率(lv)的(de)鏡面金屬基板上的(de)高(gao)(gao)光(guang)(guang)效集成(cheng)面光(guang)(guang)源技術(shu)(shu)(shu)(shu)，此技術(shu)(shu)(shu)(shu)剔除了(le)支架概念(nian)，無電(dian)鍍、無回(hui)流(liu)焊、無貼片工序，因此工序減少(shao)近(jin)三分(fen)(fen)之(zhi)一，成(cheng)本也(ye)節約了(le)三分(fen)(fen)之(zhi)一。[1] COB光(guang)(guang)源可以簡單理解為高(gao)(gao)功率(lv)集成(cheng)面光(guang)(guang)源，可以根(gen)據(ju)產(chan)品(pin)外形結(jie)構設(she)(she)(she)計(ji)光(guang)(guang)源的(de)出光(guang)(guang)面積和(he)外形尺寸。產(chan)品(pin)特點：便(bian)(bian)宜，方(fang)便(bian)(bian)電(dian)性(xing)穩定(ding)，電(dian)路設(she)(she)(she)計(ji)、光(guang)(guang)學設(she)(she)(she)計(ji)、散熱設(she)(she)(she)計(ji)科學合理；采用(yong)(yong)熱沉工藝技術(shu)(shu)(shu)(shu)，保(bao)證 LED具有業界領先的(de)熱流(liu)明(ming)(ming)維(wei)持率(lv)(95%)。便(bian)(bian)于(yu)產(chan)品(pin)的(de)二(er)次光(guang)(guang)學配(pei)套，提(ti)高(gao)(gao)照明(ming)(ming)質量。；高(gao)(gao)顯(xian)色(se)、發光(guang)(guang)均勻(yun)、無光(guang)(guang)斑、健康環(huan)保(bao)。安裝(zhuang)簡單，使用(yong)(yong)方(fang)便(bian)(bian)，降低(di)燈具設(she)(she)(she)計(ji)難(nan)度，節約燈具加工及后續維(wei)護成(cheng)本。 我(wo)司代理的(de)東洋光(guang)(guang)電(dian)TOYONIA YOLL COB光(guang)(guang)源HR(high reliability)系(xi)列：YOLL COB光(guang)(guang)源之(zhi)HR系(xi)列產(chan)品(pin)應用(yong)(yong)自主(zhu)“New material struetare"(NMS)技術(shu)(shu)(shu)(shu)，YOLL COB光(guang)(guang)源結(jie)構物(wu)理強度提(ti)升30-50%應用(yong)(yong)“NMS”技術(shu)(shu)(shu)(shu)，高(gao)(gao)可靠性(xing)，高(gao)(gao)穩定(ding)性(xing)；亮度和(he)顏色(se)一致性(xing)最佳：統一和(he)清晰的(de)光(guang)(guang)束：較高(gao)(gao)的(de)抗沖擊(ji)，抗擠壓物(wu)理強度：耐(nai)(nai)溫耐(nai)(nai)濕耐(nai)(nai)候 應用(yong)(yong)范圍：射燈，par燈，軌(gui)道燈，室(shi)內、室(shi)外照明(ming)(ming)，筒燈，導(dao)軌(gui)燈

dob和cob燈珠哪個更好？

答：DOB是(shi)(shi)將(jiang)電(dian)(dian)源(yuan)和(he)光(guang)源(yuan)布置在一(yi)(yi)(yi)塊鋁基板上，做到(dao)了(le)“去電(dian)(dian)源(yuan)化”是(shi)(shi)一(yi)(yi)(yi)種(zhong)應(ying)用(yong)方(fang)式。而COB是(shi)(shi)一(yi)(yi)(yi)種(zhong)封(feng)裝方(fang)式，是(shi)(shi)將(jiang)N多(duo)的(de)芯(xin)片串(chuan)并聯到(dao)一(yi)(yi)(yi)個整體的(de)基板上進行(xing)封(feng)裝出來的(de)面光(guang)源(yuan)

如何知道cob燈珠芯片的好壞？

cob 燈(deng)(deng)珠芯(xin)片工作時候要目視 看起(qi)來比較炫搶眼，cob 筒(tong)燈(deng)(deng)相對柔和，天花燈(deng)(deng)可以使被罩物體的(de)亮(liang)(liang)度稍微亮(liang)(liang)點，同時注意墻面上的(de)光斑是不一(yi)樣的(de)。

cob燈珠如何測量維修？

用萬用表表筆測量燈(deng)珠正(zheng)負(fu)極看是否(fou)亮，不亮更換燈(deng)珠，加點導熱(re)膠

以上就是(shi)小編對(dui)于 燈珠和cob的(de)區別問(wen)題和相關問(wen)題的(de)解(jie)答了，希望對(dui)你(ni)有用
