led燈珠如何檢查好壞

4種簡易測(ce)試好壞的方法：

1、用眼睛(jing)觀(guan)察，如果(guo)LED燈珠外(wai)觀(guan)燒(shao)傷，或內部芯片發黑，那是對(dui)LED燈珠的物(wu)理損(sun)害，即LED燈珠物(wu)理損(sun)壞(huai)。

2、如果(guo)手(shou)頭有干(gan)電(dian)池，可(ke)采(cai)用(yong)2顆1.5V的(de)電(dian)池串(chuan)聯成(cheng)3V的(de)一個電(dian)池組(zu)，正反兩端接(jie)上，不亮(liang)說明可(ke)能燈珠壞了。

3、采用(yong)(yong)(yong)萬(wan)用(yong)(yong)(yong)表的(de)測量(liang)方(fang)法(fa)。如何用(yong)(yong)(yong)簡易方(fang)法(fa)判(pan)斷led燈(deng)(deng)(deng)珠(zhu)(zhu)(zhu)好壞led燈(deng)(deng)(deng)珠(zhu)(zhu)(zhu)怎么測試(shi)好壞萬(wan)用(yong)(yong)(yong)表判(pan)斷led燈(deng)(deng)(deng)珠(zhu)(zhu)(zhu)質量(liang)的(de)方(fang)法(fa)主要有：a、用(yong)(yong)(yong)萬(wan)用(yong)(yong)(yong)表紅筆(bi)連(lian)接LED燈(deng)(deng)(deng)珠(zhu)(zhu)(zhu)的(de)正極觸(chu)點，用(yong)(yong)(yong)萬(wan)用(yong)(yong)(yong)表黑筆(bi)連(lian)接負極觸(chu)點，當LED燈(deng)(deng)(deng)珠(zhu)(zhu)(zhu)出現微小亮度時，就是(shi)(shi)好的(de)，否則可能(neng)已(yi)經損壞。b、用(yong)(yong)(yong)數(shu)字萬(wan)用(yong)(yong)(yong)表測量(liang)LED燈(deng)(deng)(deng)珠(zhu)(zhu)(zhu)的(de)正負極通(tong)斷情況(kuang)，如果(guo)用(yong)(yong)(yong)指針萬(wan)用(yong)(yong)(yong)表測量(liang)，用(yong)(yong)(yong)10KΩ檔，導通(tong)時能(neng)直觀地看到LED燈(deng)(deng)(deng)珠(zhu)(zhu)(zhu)的(de)亮度，就是(shi)(shi)好的(de)LED燈(deng)(deng)(deng)珠(zhu)(zhu)(zhu)。

led燈亮度測試方法

LED顏色及亮(liang)度的測試方(fang)法有如(ru)下幾種：

1、 人(ren)眼識別： 依靠作業(ye)人(ren)員的眼睛觀察判斷LED顏(yan)色及亮度(du)是(shi)否(fou)正確，該方法的優點(dian)是(shi)簡(jian)單，缺點(dian)是(shi)完全依賴人(ren)來判斷，容易產生由于人(ren)員的紀(ji)律(lv)不佳(jia)導(dao)致產品品質(zhi)無法把(ba)控(kong)，同時無法做(zuo)到自動化。

2、 專業(ye)的(de)(de)LED自動(dong)化(hua)(hua)測(ce)試(shi)儀(yi)(yi)： 該(gai)種(zhong)(zhong)方法是通過光纖到(dao)LED的(de)(de)光導入(ru)到(dao)LED自動(dong)化(hua)(hua)測(ce)試(shi)儀(yi)(yi)中，LED自動(dong)化(hua)(hua)測(ce)試(shi)儀(yi)(yi)中對光進行分析后，一般會返回多種(zhong)(zhong)格(ge)式(shi)的(de)(de)顏色及(ji)亮(liang)度(du)的(de)(de)值，如RGB, Hue, 飽(bao)和度(du)，亮(liang)度(du)，xy值等(deng)等(deng)。該(gai)種(zhong)(zhong)方法是準確性高，自動(dong)化(hua)(hua)程度(du)高。缺點(dian)是需要額外的(de)(de)成本。主流的(de)(de)LED測(ce)試(shi)儀(yi)(yi)有Feasa LED測(ce)試(shi)儀(yi)(yi)和iCAT LED自動(dong)化(hua)(hua)測(ce)試(shi)儀(yi)(yi)。Feasa LED 測(ce)試(shi)儀(yi)(yi)的(de)(de)長處是輸出格(ge)式(shi)多，缺點(dian)是價格(ge)過高。 iCAT LED測(ce)試(shi)儀(yi)(yi)功(gong)能和Feasa相當，但價格(ge)優勢明(ming)顯，很適合(he)自動(dong)化(hua)(hua)測(ce)試(shi)的(de)(de)運用。

3、 工(gong)業(ye)攝(she)像頭：用工(gong)業(ye)攝(she)像頭對LED進行拍(pai)照(zhao)，然后分析圖像來判斷(duan)LED的顏(yan)色及亮度。這種(zhong)方式在一(yi)次(ci)測試很多數量的LED時有優勢，但同(tong)樣有精確度不夠等問題。

怎樣檢測單個led燈珠是否亮的手段

用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)和(he)電(dian)(dian)(dian)(dian)(dian)(dian)阻檔測(ce)。5730燈(deng)(deng)(deng)(deng)珠正(zheng)向(xiang)(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)是(shi)(shi)約0.5至(zhi)0.1nF、反向(xiang)(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)比正(zheng)向(xiang)(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)稍小、不(bu)同品牌和(he)型號測(ce)出(chu)(chu)(chu)的不(bu)一(yi)樣、有(you)的正(zheng)反向(xiang)(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)(rong)都(dou)可(ke)低(di)至(zhi)約0.07nF。是(shi)(shi)以上(shang)(shang)值(zhi)的、能用(yong)3.3伏(fu)(fu)(fu)電(dian)(dian)(dian)(dian)(dian)(dian)點(dian)亮且亮度正(zheng)常(chang)、都(dou)算正(zheng)常(chang)。用(yong)3.3伏(fu)(fu)(fu)電(dian)(dian)(dian)(dian)(dian)(dian)試(shi)纔(cai)是(shi)(shi)關鍵。3.3伏(fu)(fu)(fu)電(dian)(dian)(dian)(dian)(dian)(dian)竝(bing)不(bu)難找、電(dian)(dian)(dian)(dian)(dian)(dian)腦上(shang)(shang)就有(you)、一(yi)般充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)上(shang)(shang)都(dou)有(you)、編程器(qi)上(shang)(shang)亦有(you)。沒辦法接出(chu)(chu)(chu)3.3伏(fu)(fu)(fu)電(dian)(dian)(dian)(dian)(dian)(dian)的話、用(yong)5伏(fu)(fu)(fu)電(dian)(dian)(dian)(dian)(dian)(dian)亦可(ke)。一(yi)般手機充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)輸出(chu)(chu)(chu)電(dian)(dian)(dian)(dian)(dian)(dian)壓是(shi)(shi)5伏(fu)(fu)(fu)、5伏(fu)(fu)(fu)電(dian)(dian)(dian)(dian)(dian)(dian)試(shi)一(yi)下竝(bing)不(bu)會燒壞燈(deng)(deng)(deng)(deng)珠。5730燈(deng)(deng)(deng)(deng)珠大(da)多可(ke)承受6.667伏(fu)(fu)(fu)電(dian)(dian)(dian)(dian)(dian)(dian)。正(zheng)常(chang)LED燈(deng)(deng)(deng)(deng)珠冷(leng)態(tai)正(zheng)反向(xiang)(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)阻都(dou)很大(da)、用(yong)一(yi)般萬用(yong)表(biao)測(ce)不(bu)出(chu)(chu)(chu)。壞LED燈(deng)(deng)(deng)(deng)珠有(you)的仍(reng)能亮、但亮度不(bu)足、能被一(yi)般萬用(yong)表(biao)測(ce)出(chu)(chu)(chu)冷(leng)態(tai)電(dian)(dian)(dian)(dian)(dian)(dian)阻。

怎么對比每個led燈珠的亮度

LED燈珠有(you)很多(duo)光(guang)學(xue)指標(biao)，比如(ru)光(guang)通(tong)量流明lm、光(guang)源發光(guang)強(qiang)度燭(zhu)光(guang)（英文縮寫Cd讀作(zuo)坎德拉(la)）、亮度Cd/m2等。

在這些指標(biao)中光(guang)(guang)通量(liang)和亮度(du)過于專業，測(ce)試也(ye)較(jiao)為復雜因此很少用。對于LED燈珠的生產(chan)廠(chang)家(jia)大(da)都(dou)用分光(guang)(guang)機(ji)去測(ce)每(mei)顆LED燈珠的發光(guang)(guang)強度(du)Cd值(zhi)，人們平時講的亮度(du)實際(ji)上就是指光(guang)(guang)源的發光(guang)(guang)強度(du)。

在沒(mei)有儀器設備的(de)情況下，直接用肉眼(yan)去鑒別燈(deng)珠的(de)發光強度是很困難的(de)，時間久了(le)還會傷(shang)到(dao)眼(yan)睛。下面介紹幾(ji)種土辦法可以來試一下:

①如分辨一個面光(guang)源(yuan)或燈條里的燈珠(zhu)亮度(du)，可(ke)以用(yong)一張白紙(zhi)覆(fu)蓋(gai)到光(guang)源(yuan)上，既可(ke)直接觀察(cha)出區別，

也可用(yong)電焊眼鏡或面罩來看，效(xiao)果也不(bu)錯(cuo)。

②如需(xu)單獨對每顆燈(deng)珠(zhu)進行比較，可花幾(ji)十元(yuan)買一個照度計，

把燈珠直接貼到感光頭上既可通(tong)過觀察(cha)讀數來進行鑒別(bie)了。

光(guang)源發光(guang)強度(du)(du)是(shi)對某一(yi)特定角(jiao)(jiao)度(du)(du)而言的(de)，所以在作比(bi)較時要注意角(jiao)(jiao)度(du)(du)一(yi)致，特別是(shi)小角(jiao)(jiao)度(du)(du)的(de)直挿形燈(deng)珠，角(jiao)(jiao)度(du)(du)稍有變化(hua)發光(guang)強度(du)(du)就會有較大變化(hua)，應(ying)做好掌控。以上(shang)是(shi)我的(de)回答。

怎么檢查led燈珠的好壞用數據線檢測

1、觀察燈珠的外觀

2、區(qu)分燈珠(zhu)的(de)陰(yin)極與(yu)陽極

3、萬用表檔(dang)位調至晶體管檔(dang)

4、萬用表紅(hong)筆與(yu)燈(deng)珠陽極(ji)接(jie)觸體(ti)接(jie)觸， 萬用表黑筆與(yu)陰(yin)極(ji)接(jie)觸體(ti)接(jie)觸。觀察(cha)是否亮燈(deng)。

5、若(ruo)燈(deng)(deng)(deng)亮(liang)，則表(biao)(biao)示燈(deng)(deng)(deng)珠(zhu)(zhu)功能上基本無礙，若(ruo)不亮(liang)燈(deng)(deng)(deng)，將(jiang)紅黑表(biao)(biao)筆(bi)交(jiao)換(huan)再測試一下。以免有些燈(deng)(deng)(deng)珠(zhu)(zhu)的(de)陰陽極與一般(ban)的(de)相(xiang)反。燈(deng)(deng)(deng)珠(zhu)(zhu)亮(liang)燈(deng)(deng)(deng)觀(guan)察燈(deng)(deng)(deng)珠(zhu)(zhu)顏色(se)，色(se)溫是否(fou)符合(he)要(yao)求。亮(liang)度是否(fou)合(he)適(shi)。選用(yong)合(he)適(shi)的(de)燈(deng)(deng)(deng)珠(zhu)(zhu)。 注意：一般(ban)LED燈(deng)(deng)(deng)珠(zhu)(zhu)正向壓降2.7-3.6V，請不要(yao)隨便給燈(deng)(deng)(deng)珠(zhu)(zhu)兩端(duan)加高于這個(ge)值(zhi)的(de)電(dian)壓。
