大家好今天來介(jie)紹1w貼(tie)片led燈珠(zhu)(led燈珠(zhu)1w電(dian)流多大)的問題，以下是(shi)小(xiao)編對此問題的歸納整理，來看(kan)看(kan)吧。 文章目錄列表:led大功率燈珠1w貼片電壓是多少led燈(deng)珠(zhu)(zhu)功率大(da)(da)(da)小不僅是(shi)由使用(yong)電(dian)壓(ya)決定的，與其(qi)(qi)額定工(gong)(gong)作(zuo)(zuo)電(dian)流大(da)(da)(da)小也密切相關。led貼片燈(deng)珠(zhu)(zhu)功率的大(da)(da)(da)小，基本上取決于所(suo)使用(yong)的半導體材料和(he)制(zhi)作(zuo)(zuo)工(gong)(gong)藝。led燈(deng)珠(zhu)(zhu)規(gui)格型號很多，必(bi)須查參(can)數(shu)才可知(zhi)道1w的燈(deng)珠(zhu)(zhu)使用(yong)的電(dian)壓(ya)。也可以用(yong)恒(heng)流源為其(qi)(qi)供電(dian)時測(ce)其(qi)(qi)工(gong)(gong)作(zuo)(zuo)電(dian)壓(ya)。用(yong)專用(yong)的led燈(deng)檢測(ce)儀可以一次(ci)測(ce)出其(qi)(qi)使用(yong)的電(dian)壓(ya)和(he)實際(ji)工(gong)(gong)作(zuo)(zuo)電(dian)流。
led大功率燈珠1w貼片電壓是多少led燈珠(zhu)功率大(da)小不(bu)僅(jin)是由使(shi)用(yong)(yong)(yong)電(dian)壓(ya)(ya)決(jue)定的，與其(qi)(qi)額定工(gong)(gong)作(zuo)電(dian)流(liu)(liu)大(da)小也密切相(xiang)關。led貼片燈珠(zhu)功率的大(da)小，基本上取決(jue)于所使(shi)用(yong)(yong)(yong)的半導(dao)體材料和制作(zuo)工(gong)(gong)藝。led燈珠(zhu)規(gui)格型號很(hen)多，必須查參數才可(ke)(ke)知道1w的燈珠(zhu)使(shi)用(yong)(yong)(yong)的電(dian)壓(ya)(ya)。也可(ke)(ke)以用(yong)(yong)(yong)恒流(liu)(liu)源為其(qi)(qi)供電(dian)時測(ce)其(qi)(qi)工(gong)(gong)作(zuo)電(dian)壓(ya)(ya)。用(yong)(yong)(yong)專用(yong)(yong)(yong)的led燈檢(jian)測(ce)儀可(ke)(ke)以一次測(ce)出其(qi)(qi)使(shi)用(yong)(yong)(yong)的電(dian)壓(ya)(ya)和實際工(gong)(gong)作(zuo)電(dian)流(liu)(liu)。 1w的led燈珠必須要焊接嗎1w的led燈珠(zhu)沒(mei)有直插式的,不(bu)(bu)(bu)焊(han)接在鋁(lv)(lv)基板(ban)(ban)上就(jiu)不(bu)(bu)(bu)能很(hen)好地散熱,散熱好當然要(yao)涂(tu)導熱膠了(le),這些都是唯一的,無可(ke)商(shang)量. 不(bu)(bu)(bu)過你為(wei)了(le)經常換(huan),可(ke)以把(ba)燈珠(zhu)都分別焊(han)在鋁(lv)(lv)基板(ban)(ban)上,引線(xian)接好插頭插座,把(ba)鋁(lv)(lv)基板(ban)(ban)與燈珠(zhu)一起拔出換(huan)下也很(hen)方(fang)便,1w的鋁(lv)(lv)基板(ban)(ban)才(cai)1-2毛一個,浪費不(bu)(bu)(bu)了(le)多(duo)少,可(ke)問題都解(jie)決了(le),不(bu)(bu)(bu)是嗎 led燈珠05w和1w區分LED燈(deng)1w和0.5w亮度區別(bie)是: 一般講,用0.5W的(de)(de)貼片LED更(geng)好。0.5W燈(deng)(deng)珠(zhu)的(de)(de)發光效率通常要(yao)高于(yu)1W燈(deng)(deng)珠(zhu)。另外,相同功(gong)率的(de)(de)燈(deng)(deng)泡,0.5W的(de)(de)LED的(de)(de)數量2倍于(yu)1W的(de)(de),LED排列更(geng)分散,便于(yu)光學設計。 從字面上(shang)就可以(yi)看到在功(gong)率上(shang)的差別(bie)(bie)，另外一(yi)個在材料，特別(bie)(bie)是所使(shi)用的芯片，一(yi)般(ban)大(da)小都(dou)相(xiang)差挺(ting)大(da)，還有(you)一(yi)個使(shi)用環境等(deng)等(deng)， 1w的led燈珠是多少伏1W的(de)led燈(deng)珠，電壓是2.79-3.99V，電流是350mA 以上就是(shi)小編對于1w貼片led燈(deng)珠(led燈(deng)珠1w電流多大(da))問(wen)題(ti)和(he)相(xiang)關(guan)問(wen)題(ti)的解(jie)答了(le)，希望對你(ni)有用(yong) |
