現在很多led線條燈廠家生產(chan)的(de)(de)(de)led燈(deng)類產(chan)品(比如護欄燈(deng)、燈(deng)杯(bei)、投射燈(deng))都采用(yong)阻容降(jiang)壓(ya)(ya)方(fang)(fang)式(shi)(shi)，然后加上(shang)一個穩(wen)壓(ya)(ya)二極管穩(wen)壓(ya)(ya)，向led供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)。這種驅(qu)(qu)(qu)動(dong)(dong)led的(de)(de)(de)方(fang)(fang)式(shi)(shi)存在(zai)極大(da)(da)的(de)(de)(de)缺(que)陷，首先效(xiao)率低(di)(di)(di)，在(zai)降(jiang)壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)(dian)阻上(shang)消(xiao)(xiao)耗(hao)大(da)(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)能(neng)(neng)，甚至有可能(neng)(neng)超過(guo)led所消(xiao)(xiao)耗(hao)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)能(neng)(neng)，且(qie)無法提供(gong)大(da)(da)電(dian)(dian)(dian)(dian)(dian)(dian)流驅(qu)(qu)(qu)動(dong)(dong)，因為電(dian)(dian)(dian)(dian)(dian)(dian)流越大(da)(da)，消(xiao)(xiao)耗(hao)在(zai)降(jiang)壓(ya)(ya)電(dian)(dian)(dian)(dian)(dian)(dian)阻上(shang)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)能(neng)(neng)就越多，所以(yi)很多產(chan)品中的(de)(de)(de)led不(bu)采用(yong)并聯(lian)方(fang)(fang)式(shi)(shi)，而采用(yong)串聯(lian)方(fang)(fang)式(shi)(shi)以(yi)減小電(dian)(dian)(dian)(dian)(dian)(dian)流。其次，穩(wen)定電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)的(de)(de)(de)能(neng)(neng)力極差，無法保證通(tong)過(guo)led的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流不(bu)超過(guo)其正常工作要求。設計時可通(tong)過(guo)降(jiang)低(di)(di)(di)led兩端的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)來供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)驅(qu)(qu)(qu)動(dong)(dong)，但這樣是以(yi)降(jiang)低(di)(di)(di)led的(de)(de)(de)亮(liang)度為代(dai)價的(de)(de)(de)。采用(yong)阻容降(jiang)壓(ya)(ya)方(fang)(fang)式(shi)(shi)驅(qu)(qu)(qu)動(dong)(dong)led時，led的(de)(de)(de)亮(liang)度不(bu)能(neng)(neng)穩(wen)定，當供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)較低(di)(di)(di)時，led的(de)(de)(de)亮(liang)度變暗：供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)源電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)較高(gao)時，led的(de)(de)(de)亮(liang)度變亮(liang)。以(yi)阻容降(jiang)壓(ya)(ya)方(fang)(fang)式(shi)(shi)驅(qu)(qu)(qu)動(dong)(dong)led的(de)(de)(de)一大(da)(da)優勢是成本低(di)(di)(di)。

    常規的貼片led線條燈灌膠在燈珠原件上面，達到防水效果，膠體覆蓋在燈珠上，燈珠的色溫就會發生改變，色溫會上漲， 沒有灌膠前的顏色好對比之前色溫會飄高，而且灌膠的話，用價格低廉的膠水，就會與燈珠膠體發生化學反應，燈珠會有死燈或者光衰的現象，用好的膠水也只會延緩燈珠光衰的 時間。而帶了透鏡的線條燈就完全沒有這些弊端，在燈珠上帶了透鏡后，就相當于給燈珠帶了一個保護罩。灌膠的膠水就不會接觸到燈珠，燈珠的色溫不會發生改 變，燈珠使用壽命更長。而且可以帶上玻璃和支架，同樣可以達到大功率led洗墻燈的效(xiao)果，看(kan)起來更(geng)加高端上檔(dang)次。
