C8 LED燈珠和T6 LED燈珠哪個亮

這兩款led燈珠不是一個概念，C8是一個手電(dian)筒的(de)(de)型號，T6是LED珠(zhu)的(de)(de)型號，以前C8用的(de)(de)大(da)部(bu)分是Q5珠(zhu)，現在T6的(de)(de)也有，T6在參數上比Q5強得多

LED燈珠(zhu)T6和U8哪一個(ge)更亮?T6在參數上比U8（Q5）更亮

燈珠一般能承受多少電壓和多少電流

電流應該最(zui)大(da)為(wei)3琥(hu)珀，它(ta)是大(da)功率燈(deng)珠最(zui)大(da)10瓦(wa)的(de)LED燈(deng)珠，實際上是發(fa)出白光(guang)(guang)的(de)發(fa)光(guang)(guang)二極(ji)管(guan)，發(fa)光(guang)(guang)二極(ji)管(guan)具有二極(ji)管(guan)的(de)所(suo)有特性(xing)，即單向導電性(xing)。

T6XML-U2LED的(de)正(zheng)向(xiang)導通(tong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)約(yue)為3.2V，最大(da)容許(xu)正(zheng)向(xiang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)為100mA。使用時不能(neng)直接(jie)(jie)連(lian)接(jie)(jie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)。必(bi)須(xu)串(chuan)聯限流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻。限流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻值(zhi)是(電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)-3.2)/珠(zhu)流(liu)(liu)(liu)，珠(zhu)流(liu)(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)一般(ban)取最大(da)值(zhi)的(de)80%。即(ji)，如(ru)果80mA例如(ru)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)為6V，則(ze)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)限制電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻值(zhi)為(6-3.2)/0.08)=35歐(ou)元(yuan)，將電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)限制電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻串(chuan)聯連(lian)接(jie)(jie)到LED上，與電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)連(lian)接(jie)(jie)即(ji)可。LED的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)不能(neng)反向(xiang)連(lian)接(jie)(jie)，相反連(lian)接(jie)(jie)的(de)話LED會關閉(bi)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)無法通(tong)過。也(ye)不能(neng)用于AC電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)。接(jie)(jie)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)3.5V，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)100mA左右!

CREE公司推出了XM-L系列珠和T6珠的區別

XML是(shi)包裝(zhuang)形(xing)式，美國CREE公司(si)開發(fa)的(de)(de)(de)下一(yi)代(dai)(dai)LED珠、U2、T6、U3等是(shi)XML的(de)(de)(de)種子(zi)類型(xing)，以3金線(xian)、6矩陣為特征，最高亮度都達到(dao)1000流明以上(shang)，現在(zai)出現了(le)XML 2代(dai)(dai)，比1代(dai)(dai)增加了(le)20%XML珠的(de)(de)(de)單位面(mian)積光效應只不過是(shi)XpE等以前(qian)幾種的(de)(de)(de)一(yi)半。但(dan)是(shi)，因(yin)為面(mian)積比XpE的(de)(de)(de)所有(you)類型(xing)都大(da)得多，所以有(you)比cree的(de)(de)(de)官方更明亮的(de)(de)(de)。
