大家好我(wo)是(shi)小編沁夢今(jin)天我(wo)們(men)來介紹(shao)led燈(deng)珠多好嗎 led車燈(deng)燈(deng)珠越(yue)(yue)多越(yue)(yue)好還是(shi)越(yue)(yue)少越(yue)(yue)好的問(wen)題，以下就是(shi)沁夢對(dui)此問(wen)題和(he)相關問(wen)題的歸納整理(li),一(yi)起來看(kan)看(kan)吧。 文章目錄導航: 相同瓦數時LED多的和LED少的燈哪個更亮為什么 這(zhe)個問題我來回答一(yi)下，本人覺得相同(tong)(tong)瓦(wa)數(shu)的話，燈(deng)(deng)珠(zhu)(zhu)少(shao)的會亮(liang)度(du)(du)高點(dian)。原(yuan)因推(tui)斷(duan)為(wei)(wei)，大(da)家(jia)知道，功(gong)率(lv)的計算方法為(wei)(wei)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)乘以電(dian)(dian)(dian)(dian)流，功(gong)率(lv)固(gu)定，可變的是電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)和電(dian)(dian)(dian)(dian)流，而(er)(er)(er)高清LED燈(deng)(deng)珠(zhu)(zhu)的工(gong)(gong)(gong)作(zuo)(zuo)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)一(yi)般(ban)為(wei)(wei)3.6到4.2V，工(gong)(gong)(gong)作(zuo)(zuo)電(dian)(dian)(dian)(dian)流一(yi)般(ban)為(wei)(wei)20到150ma，而(er)(er)(er)普(pu)通(tong)的LED燈(deng)(deng)珠(zhu)(zhu)工(gong)(gong)(gong)作(zuo)(zuo)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)為(wei)(wei)0.7到1.6V，工(gong)(gong)(gong)作(zuo)(zuo)電(dian)(dian)(dian)(dian)流一(yi)般(ban)為(wei)(wei)10到20MA，基(ji)本上裝亮(liang)度(du)(du)燈(deng)(deng)珠(zhu)(zhu)的工(gong)(gong)(gong)作(zuo)(zuo)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)戓(ge)電(dian)(dian)(dian)(dian)流是普(pu)通(tong)燈(deng)(deng)珠(zhu)(zhu)的兩倍(bei)戓(ge)以上，相同(tong)(tong)瓦(wa)數(shu)，只有電(dian)(dian)(dian)(dian)流戓(ge)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)高才(cai)能減少(shao)數(shu)量，所以推(tui)斷(duan)出燈(deng)(deng)珠(zhu)(zhu)少(shao)而(er)(er)(er)達到相同(tong)(tong)功(gong)率(lv)的都用高亮(liang)度(du)(du)燈(deng)(deng)珠(zhu)(zhu)，而(er)(er)(er)高亮(liang)度(du)(du)燈(deng)(deng)珠(zhu)(zhu)和普(pu)通(tong)燈(deng)(deng)珠(zhu)(zhu)對比起來亮(liang)度(du)(du)提高近(jin)百倍(bei)，光電(dian)(dian)(dian)(dian)轉換效率(lv)更高，穿透力更強，因此推(tui)斷(duan)出燈(deng)(deng)珠(zhu)(zhu)少(shao)的亮(liang)度(du)(du)會高一(yi)點(dian)。
led車燈燈珠越多越好嗎 并非(fei)越(yue)多(duo)越(yue)好，也不一定越(yue)少越(yue)好，需要根(gen)據具體狀況分(fen)析(xi)。 LED日光燈，需要較多數目的中小功率LED，才能保(bao)證(zheng)發光均勻。但是貼裝過(guo)程比較耗(hao)時。 LED射(she)燈通常都是用單顆(ke)(ke)大功率光源來做，顯然，多顆(ke)(ke)中小功率LED的配光無法實現。 led燈珠越多越好還是越少越好 肯定不(bu)(bu)是啊。首先要(yao)弄清楚燈(deng)(deng)(deng)(deng)珠(zhu)是什(shen)么(me)燈(deng)(deng)(deng)(deng)珠(zhu)，小功(gong)(gong)率的(de)(de)還(huan)是大(da)功(gong)(gong)率的(de)(de)，國產的(de)(de)還(huan)是進口的(de)(de)。還(huan)要(yao)看什(shen)么(me)燈(deng)(deng)(deng)(deng)具(ju)，照明類燈(deng)(deng)(deng)(deng)具(ju)都是用大(da)功(gong)(gong)率燈(deng)(deng)(deng)(deng)珠(zhu)，而大(da)功(gong)(gong)率燈(deng)(deng)(deng)(deng)珠(zhu)發熱(re)比較厲害(hai)，所以不(bu)(bu)是數(shu)量越(yue)多越(yue)好，如果(guo)大(da)功(gong)(gong)率燈(deng)(deng)(deng)(deng)珠(zhu)太多，發熱(re)超過(guo)了燈(deng)(deng)(deng)(deng)體的(de)(de)散熱(re)速度，那(nei)么(me)燈(deng)(deng)(deng)(deng)珠(zhu)就容易燒壞，壽(shou)命不(bu)(bu)長 LED路燈是單珠好還是多珠好了 多的好彈珠的壞(huai)了(le)就不亮了(le)多的壞(huai)一個無(wu)所(suo)謂啊反正我是這樣考慮(lv)的至于功耗什么的應該不用考慮(lv)LED本身(shen)就是節能產品 led射燈是單珠好還是多珠好 多(duo)燈(deng)(deng)珠(zhu)好(hao)，分析如下 單珠(zhu)一般(ban)為大(da)功率燈(deng)(deng)珠(zhu)或者(zhe)cob集成(cheng)燈(deng)(deng)珠(zhu)，這(zhe)類燈(deng)(deng)珠(zhu)發(fa)光面(mian)小，加透鏡后光分散(san)(san)的太利害，有(you)效(xiao)照明面(mian)積大(da)幅(fu)減小，且局(ju)部溫升大(da)影響(xiang)光源壽命，多(duo)燈(deng)(deng)珠(zhu)發(fa)光面(mian)大(da)，散(san)(san)熱性能好(hao)，有(you)效(xiao)照明面(mian)積大(da)，推(tui)薦(jian)采用(yong)多(duo)燈(deng)(deng)珠(zhu)方案 以上就是(shi)天成小編(bian)對于led燈(deng)珠多好嗎 led車(che)燈(deng)燈(deng)珠越(yue)多越(yue)好還是(shi)越(yue)少越(yue)好問(wen)題和(he)相關問(wen)題的解答了，希望對你有(you)用(yong) 【責任編(bian)輯：沁夢】 |
