大(da)家(jia)好今(jin)天(tian)來介(jie)紹led同功率燈珠多(為什么同樣(yang)(yang)瓦數的Led燈不一樣(yang)(yang)亮)的問題(ti)，以下是小(xiao)編對此問題(ti)的歸(gui)納整理，來看(kan)看(kan)吧。 文章目錄列表:
相同瓦數時LED多的和LED少的燈哪個更亮為什么這個(ge)問題我來回答(da)一下，本(ben)人覺得相(xiang)同(tong)(tong)(tong)瓦數的話，燈珠(zhu)(zhu)(zhu)(zhu)少(shao)(shao)的會亮(liang)(liang)度(du)高(gao)(gao)(gao)(gao)點。原因推(tui)斷(duan)為(wei)，大家(jia)知道，功(gong)率的計(ji)算方法為(wei)電(dian)(dian)(dian)(dian)(dian)壓(ya)乘以(yi)電(dian)(dian)(dian)(dian)(dian)流，功(gong)率固(gu)定，可變的是(shi)電(dian)(dian)(dian)(dian)(dian)壓(ya)和電(dian)(dian)(dian)(dian)(dian)流，而高(gao)(gao)(gao)(gao)清LED燈珠(zhu)(zhu)(zhu)(zhu)的工(gong)(gong)(gong)作電(dian)(dian)(dian)(dian)(dian)壓(ya)一般為(wei)3.6到(dao)4.2V，工(gong)(gong)(gong)作電(dian)(dian)(dian)(dian)(dian)流一般為(wei)20到(dao)150ma，而普(pu)通的LED燈珠(zhu)(zhu)(zhu)(zhu)工(gong)(gong)(gong)作電(dian)(dian)(dian)(dian)(dian)壓(ya)為(wei)0.7到(dao)1.6V，工(gong)(gong)(gong)作電(dian)(dian)(dian)(dian)(dian)流一般為(wei)10到(dao)20MA，基本(ben)上裝亮(liang)(liang)度(du)燈珠(zhu)(zhu)(zhu)(zhu)的工(gong)(gong)(gong)作電(dian)(dian)(dian)(dian)(dian)壓(ya)戓(ge)(ge)(ge)電(dian)(dian)(dian)(dian)(dian)流是(shi)普(pu)通燈珠(zhu)(zhu)(zhu)(zhu)的兩倍戓(ge)(ge)(ge)以(yi)上，相(xiang)同(tong)(tong)(tong)瓦數，只有(you)電(dian)(dian)(dian)(dian)(dian)流戓(ge)(ge)(ge)電(dian)(dian)(dian)(dian)(dian)壓(ya)高(gao)(gao)(gao)(gao)才能減(jian)少(shao)(shao)數量，所以(yi)推(tui)斷(duan)出燈珠(zhu)(zhu)(zhu)(zhu)少(shao)(shao)而達到(dao)相(xiang)同(tong)(tong)(tong)功(gong)率的都用(yong)高(gao)(gao)(gao)(gao)亮(liang)(liang)度(du)燈珠(zhu)(zhu)(zhu)(zhu)，而高(gao)(gao)(gao)(gao)亮(liang)(liang)度(du)燈珠(zhu)(zhu)(zhu)(zhu)和普(pu)通燈珠(zhu)(zhu)(zhu)(zhu)對比起(qi)來亮(liang)(liang)度(du)提高(gao)(gao)(gao)(gao)近百倍，光(guang)電(dian)(dian)(dian)(dian)(dian)轉換效率更(geng)高(gao)(gao)(gao)(gao)，穿(chuan)透力更(geng)強(qiang)，因此(ci)推(tui)斷(duan)出燈珠(zhu)(zhu)(zhu)(zhu)少(shao)(shao)的亮(liang)(liang)度(du)會高(gao)(gao)(gao)(gao)一點。
led燈一瓦是幾個燈珠照明用的(de)Led燈一瓦有1～2個燈珠。 Ied燈采用(yong)第四代綠色環保、大功率白光LED固(gu)態光源，光效高，使用(yong)壽命長(chang)達(da)10萬小(xiao)時(shi)，可(ke)實現長(chang)期(qi)免維護；人性化的(de)產品設(she)計(ji)，客戶可(ke)按不同的(de)照明場所選擇相適應的(de)工作電壓。 led燈同樣瓦數是不是燈珠越多亮度越好啊按原理來說只要(yao)w數相同的(de)led燈(deng)泡亮度都一樣,但實(shi)際上單粒led功率越(yue)(yue)小的(de)發光效率越(yue)(yue)高,也就是(shi)燈(deng)珠越(yue)(yue)多會越(yue)(yue)亮些,不過亮的(de)這點(dian)也有(you)限,不把二個(ge)放在一起(qi)比較(jiao)是(shi)基本感覺不到的(de). 汽車LED大燈相同瓦數燈珠多的好還是燈珠少的好（從聚光方面和耐用方面分別說說）燈的發光點多意味著制造難度低，發光二(er)極(ji)管小良品率高，在組(zu)成大燈時(shi)散熱也好處理，聚光都是靠(kao)透(tou)鏡(jing)。 led燈同一瓦數為什么燈有多有少led燈同一(yi)瓦數為什么燈有(you)多(duo)有(you)少： 你可以這么理解，12顆led燈(deng)珠那(nei)一款(kuan)，流過(guo)每(mei)個燈(deng)珠的電(dian)流只有額定電(dian)流的一半， 可是(shi)亮(liang)度(du)卻(que)能達到(dao)額定亮(liang)度(du)的70%，因此(ci)它的亮(liang)度(du)要(yao)比6顆燈(deng)珠那(nei)款(kuan)要(yao)高(gao)不少，功率卻(que)是(shi)一樣的。 廠家沒有(you)騙(pian)你。5730一(yi)個(ge)可以推0.5w。普通六(liu)個(ge)推三瓦(wa)。一(yi)般高端的(de)(de)就會用多一(yi)點，大材小用就會延(yan)長(chang)燈的(de)(de)壽(shou)命和提高亮度。 以上就是小(xiao)編對(dui)于(yu)led同(tong)功率燈珠多(為什么同(tong)樣(yang)瓦數(shu)的Led燈不一樣(yang)亮)問題和相關問題的解答了，希望對(dui)你有用 |
