總體來說我認(rèn)為LED大燈更好，當(dāng)然鹵素車燈也是有它的優(yōu)點(diǎn)的，但總的來說缺點(diǎn)大于優(yōu)點(diǎn)。LED大燈亮度更高，更加節(jié)能用過節(jié)能LED燈的小伙伴都知道，節(jié)能燈不光更省電，而且亮度也更高，發(fā)出的光也更加的白。當(dāng)然汽車的LED大燈也是這樣，它不光比鹵素大燈更亮，而且它的聚光性也更好。此外LED大燈的功率也比鹵素大燈更小，消耗的電量更少，耗電*相當(dāng)于傳統(tǒng)燈泡的1/10。LED大燈更好看LED燈珠較小，并可以根據(jù)造型的需要排列成不同的形狀，這也就給了汽車造型師更大的發(fā)揮空間，于是現(xiàn)在的車外形也越來越好看了。所以在買車的時候，大家還是更愿意選擇LED大燈。圓環(huán)形LED尾燈LED大燈更加智能化得益于LED的多顆燈珠的設(shè)計(jì)方式，LED頭燈可以實(shí)現(xiàn)各種智能功能。比如隨動轉(zhuǎn)向頭燈、自動遠(yuǎn)近光燈、LED流水轉(zhuǎn)向燈、主動LED大燈、可投射圖像大燈等等。更加智能和先進(jìn)的LED大燈使我們的用車更加方便，也更加安全。避免遠(yuǎn)光直射對象來車鹵素大燈：成本低、易維護(hù)是它大的優(yōu)點(diǎn)但LED的這些優(yōu)點(diǎn)是跟它成本成正比的，普通一輛20萬合資車，它的一個LED頭燈差不多要5千到1萬人民幣不等，一些豪華車的LED頭燈動則3萬以上。而一輛鹵素大燈多不過幾千塊錢，在維修更換方面，顯然鹵素大燈成本更低。上海先盛照明電器有限公司是一家專業(yè)提供LED的公司。北京工業(yè)LED量大從優(yōu)</p><p style="text-indent:25px">上海先盛照明電器有限公司致力于提供LED，有需求可以來電咨詢！重慶專業(yè)LED哪里買</p><p>平角的LED燈珠直插可以做到90-110度。角度越小，聚光性越好，光線越集中，光線射得更遠(yuǎn)。缺點(diǎn)是照射范圍有限。LED燈珠貼片，一般角度都是平面120度，因?yàn)榻嵌却?，發(fā)光均勻，通常在照常照明產(chǎn)品上大量使用。比如，日光燈管，球泡燈，面板燈，很多照明產(chǎn)品上用的都是SMDLED貼片燈珠。LED燈珠貼片可以上高速SMD，過回流焊的溫度可以達(dá)到260度，重要的是LED燈珠貼片可以批量上高速貼片燈，批量工業(yè)化生產(chǎn)，照明產(chǎn)品上的話，省人工，機(jī)器貼裝，效率更高，焊接不良率更低。而LED燈珠（LED燈珠直插式）因?yàn)榻嵌刃?，聚光性好，但是因?yàn)橹挥袃蓚€引腳散熱，所以，一般只能過波峰焊。或者，手工電烙鐵焊接，焊接要求焊接時間短，對焊接工人的焊接技術(shù)有要求，否則會產(chǎn)生較多的不良率。LED燈珠和LED貼片哪個更好？其實(shí)重要的，還是要看你是用在什么產(chǎn)品上的，如果是用在大功率，或者大瓦數(shù)的照明產(chǎn)品上，一般是建議使用LED燈珠貼片式的，成本更低，效率更高。而如果是用在指示燈上，或者要求聚光，高亮的，小功率的，一般可以選用上海先盛照明電器有限公司LED燈珠直插式的。因此，LED燈珠和LED貼片兩種發(fā)光二極管，本質(zhì)上就沒有太大的區(qū)別，都是LED燈珠的封裝方式。重慶專業(yè)LED哪里買</p></p><br
