大家好我(wo)是(shi)小(xiao)編一(yi)夢今天我(wo)們來(lai)介紹辨別led燈珠(zhu) 怎樣區分led燈珠(zhu)型號的問題(ti)，以下(xia)就是(shi)一(yi)夢對(dui)此問題(ti)和相關問題(ti)的歸納整理(li),一(yi)起(qi)來(lai)看看吧。 文章目錄導航: 怎么檢查led燈珠好壞 區分LED燈(deng)(deng)(deng)(deng)珠的(de)(de)(de)(de)(de)(de)(de)優劣方法：一、看整(zheng)體燈(deng)(deng)(deng)(deng)具的(de)(de)(de)(de)(de)(de)(de)功(gong)率(lv)因數(shu)：功(gong)率(lv)因數(shu)低，說明使(shi)用(yong)(yong)(yong)(yong)的(de)(de)(de)(de)(de)(de)(de)驅(qu)動電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)、電(dian)(dian)(dian)(dian)路(lu)設(she)計(ji)不好(hao)(hao)，會(hui)大(da)大(da)降低燈(deng)(deng)(deng)(deng)具的(de)(de)(de)(de)(de)(de)(de)使(shi)用(yong)(yong)(yong)(yong)壽(shou)(shou)(shou)命(ming)(ming)(ming)，功(gong)率(lv)因數(shu)低，使(shi)用(yong)(yong)(yong)(yong)再好(hao)(hao)燈(deng)(deng)(deng)(deng)珠的(de)(de)(de)(de)(de)(de)(de)燈(deng)(deng)(deng)(deng)具壽(shou)(shou)(shou)命(ming)(ming)(ming)也(ye)不會(hui)長(chang)。二(er)、看燈(deng)(deng)(deng)(deng)具散熱條件--材(cai)料(liao)、結構(gou)：LED燈(deng)(deng)(deng)(deng)具散熱也(ye)是很重要(yao)的(de)(de)(de)(de)(de)(de)(de)，同(tong)樣功(gong)率(lv)因數(shu)的(de)(de)(de)(de)(de)(de)(de)燈(deng)(deng)(deng)(deng)具和(he)同(tong)品(pin)質(zhi)(zhi)的(de)(de)(de)(de)(de)(de)(de)燈(deng)(deng)(deng)(deng)珠，如果散熱條件不好(hao)(hao)，燈(deng)(deng)(deng)(deng)珠在高(gao)(gao)(gao)(gao)溫下工作，光衰會(hui)很大(da)，燈(deng)(deng)(deng)(deng)具壽(shou)(shou)(shou)命(ming)(ming)(ming)會(hui)減(jian)少。三(san)、看燈(deng)(deng)(deng)(deng)珠品(pin)質(zhi)(zhi)：燈(deng)(deng)(deng)(deng)珠品(pin)質(zhi)(zhi)決定(ding)(ding)(ding)于芯片品(pin)質(zhi)(zhi)和(he)封裝技術。四、看燈(deng)(deng)(deng)(deng)具使(shi)用(yong)(yong)(yong)(yong)的(de)(de)(de)(de)(de)(de)(de)驅(qu)動電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)，電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)的(de)(de)(de)(de)(de)(de)(de)使(shi)用(yong)(yong)(yong)(yong)壽(shou)(shou)(shou)命(ming)(ming)(ming)相對燈(deng)(deng)(deng)(deng)具的(de)(de)(de)(de)(de)(de)(de)其(qi)他部分來說，壽(shou)(shou)(shou)命(ming)(ming)(ming)要(yao)短很多，電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)的(de)(de)(de)(de)(de)(de)(de)壽(shou)(shou)(shou)命(ming)(ming)(ming)影響燈(deng)(deng)(deng)(deng)具的(de)(de)(de)(de)(de)(de)(de)整(zheng)體壽(shou)(shou)(shou)命(ming)(ming)(ming)，燈(deng)(deng)(deng)(deng)珠的(de)(de)(de)(de)(de)(de)(de)理論壽(shou)(shou)(shou)命(ming)(ming)(ming)在5-10萬(wan)小時，而電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)的(de)(de)(de)(de)(de)(de)(de)壽(shou)(shou)(shou)命(ming)(ming)(ming)在0.2-3萬(wan)小時，電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)的(de)(de)(de)(de)(de)(de)(de)設(she)計(ji)與材(cai)料(liao)選(xuan)擇會(hui)決定(ding)(ding)(ding)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)的(de)(de)(de)(de)(de)(de)(de)使(shi)用(yong)(yong)(yong)(yong)壽(shou)(shou)(shou)命(ming)(ming)(ming)。五、看光效(xiao)(xiao)：同(tong)樣的(de)(de)(de)(de)(de)(de)(de)燈(deng)(deng)(deng)(deng)珠功(gong)率(lv)，光效(xiao)(xiao)越高(gao)(gao)(gao)(gao)，亮(liang)度越高(gao)(gao)(gao)(gao)，同(tong)樣的(de)(de)(de)(de)(de)(de)(de)照明亮(liang)度，耗電(dian)(dian)(dian)(dian)越小，越節能。六、看電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)效(xiao)(xiao)率(lv)，電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)效(xiao)(xiao)率(lv)越高(gao)(gao)(gao)(gao)越好(hao)(hao)，越高(gao)(gao)(gao)(gao)，說明電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)本身的(de)(de)(de)(de)(de)(de)(de)功(gong)耗越小，輸(shu)出的(de)(de)(de)(de)(de)(de)(de)功(gong)率(lv)越大(da)。七(qi)、看是否(fou)符合安(an)全(quan)標準，我國LED燈(deng)(deng)(deng)(deng)具安(an)全(quan)標準已(yi)經出臺，請按國家規定(ding)(ding)(ding)的(de)(de)(de)(de)(de)(de)(de)安(an)全(quan)標準選(xuan)擇LED燈(deng)(deng)(deng)(deng)具。八(ba)、看做工是否(fou)精細。一個品(pin)質(zhi)(zhi)好(hao)(hao)的(de)(de)(de)(de)(de)(de)(de)LED燈(deng)(deng)(deng)(deng)具，除上面(mian)提到的(de)(de)(de)(de)(de)(de)(de)幾個主要(yao)方面(mian)外，還(huan)要(yao)根據不同(tong)的(de)(de)(de)(de)(de)(de)(de)使(shi)用(yong)(yong)(yong)(yong)環(huan)境，有不同(tong)的(de)(de)(de)(de)(de)(de)(de)技術要(yao)求，如防(fang)潮、防(fang)塵、防(fang)磁、防(fang)雷擊(ji)等。
led燈珠型號很多種如何快速區分 我們(men)先(xian)看(kan)一(yi)下LED燈(deng)珠的分(fen)類。 LED燈(deng)珠(zhu)(zhu)(zhu)按封(feng)裝(zhuang)類型主要(yao)可以(yi)分為貼片led燈(deng)珠(zhu)(zhu)(zhu)，插件led燈(deng)珠(zhu)(zhu)(zhu)，大(da)功率led燈(deng)珠(zhu)(zhu)(zhu)和(he)COB led燈(deng)珠(zhu)(zhu)(zhu)幾種(zhong)。 貼(tie)(tie)(tie)(tie)片(pian)led燈(deng)(deng)珠(zhu)可以又(you)分(fen)別小功(gong)率(lv)，中功(gong)率(lv)和大功(gong)率(lv)貼(tie)(tie)(tie)(tie)片(pian)led燈(deng)(deng)珠(zhu)。如果，你(ni)(ni)是找指示類的(de)LED燈(deng)(deng)珠(zhu)，一般來說，你(ni)(ni)就需(xu)要找小功(gong)率(lv)的(de)LED燈(deng)(deng)珠(zhu)。比(bi)如，0.06w的(de)貼(tie)(tie)(tie)(tie)片(pian)led燈(deng)(deng)珠(zhu)，比(bi)如0201貼(tie)(tie)(tie)(tie)片(pian)燈(deng)(deng)珠(zhu)，0402貼(tie)(tie)(tie)(tie)片(pian)燈(deng)(deng)珠(zhu)，0603貼(tie)(tie)(tie)(tie)片(pian)燈(deng)(deng)珠(zhu)，0805貼(tie)(tie)(tie)(tie)片(pian)燈(deng)(deng)珠(zhu)和1206貼(tie)(tie)(tie)(tie)片(pian)燈(deng)(deng)珠(zhu)等(deng)。或者3mm直插(cha)(cha)led燈(deng)(deng)珠(zhu)，5mm直插(cha)(cha)led燈(deng)(deng)珠(zhu)，8mm 直插(cha)(cha)led燈(deng)(deng)珠(zhu)和10mm 直插(cha)(cha)led燈(deng)(deng)珠(zhu)等(deng)。 當然，也有一些異形的插件燈(deng)珠(zhu)，比如 2mm奶嘴型，4mm平頭(tou)型，234方形，557方形，食人魚插件燈(deng)珠(zhu)，小(xiao)蝴蝶燈(deng)珠(zhu)等。led燈(deng)珠(zhu)型號怎么區(qu)分這樣的話，你按封裝類型結合(he)功率大小(xiao)來區(qu)分，其(qi)實就比較容易(yi)了。 led燈珠判斷方法
萬(wan)用表測試(shi)：用萬(wan)用表來(lai)測試(shi)燈珠(zhu)的好(hao)壞，若萬(wan)用表不亮表明燈珠(zhu)已經損壞。 遙控(kong)器測試：拿兩根(gen)線卡在遙控(kong)器的電池上(shang)，再用兩根(gen)線的另一端(duan)放(fang)在燈(deng)珠的兩邊，若(ruo)燈(deng)亮(liang)則表示(shi)未損壞，燈(deng)未亮(liang)則表示(shi)已損壞。 LED燈珠怎么辨別好壞和真偽 燈(deng)珠(zhu)的質(zhi)量首先(xian)看(kan)芯片，目前國內的SMD燈(deng)珠(zhu)基本上都是山(shan)寨(zhai)的也就是廠家自己搞的，好一點(dian)的有晶元等(deng)。另外一個角度上來(lai)說，燈(deng)珠(zhu)的質(zhi)量看(kan)燈(deng)珠(zhu)測試過程中的光(guang)衰情況。成品的SMD貼片，看(kan)一致性，也就是說亮度的均勻。 LED燈珠怎么分好壞 區分LED燈(deng)珠的(de)好壞很簡(jian)單，首先(xian)用(yong)萬用(yong)表電阻(zu)檔測(ce)量LED燈(deng)兩端值數，它和普通二極(ji)管(guan)的(de)測(ce)量方法相同，因為(wei)LED本身就是(shi)(shi)發光(guang)二極(ji)管(guan)，正反向阻(zu)值相差很大，一般(ban)反向阻(zu)值無(wu)窮(qiong)大，正向阻(zu)值一般(ban)幾(ji)十歐(ou)姆為(wei)正常(chang)，反之就是(shi)(shi)有問題(ti)的(de)二機管(guan)，再用(yong)額定電壓通電看(kan)看(kan)是(shi)(shi)否發光(guang)即(ji)可辨認LED二極(ji)管(guan)好壞 以(yi)上(shang)就(jiu)是天(tian)成小編對(dui)于(yu)辨別led燈珠 怎樣區(qu)分led燈珠型號問題和相關問題的(de)解答(da)了，希(xi)望對(dui)你有用 【責任編輯：一夢】 |
