發(fā)光二極管簡稱為LED。由含鎵（Ga）、砷（As）、磷（P）、氮（N）等的化合物制成。當(dāng)電子與空穴復(fù)合時(shí)能輻射出可見光，因而可以用來制成發(fā)光二極管。在電路及儀器中作為指示燈，或者組成文字或數(shù)字顯示。砷化鎵二極管發(fā)紅光，磷化鎵二極管發(fā)綠光，碳化硅二極管發(fā)黃光，氮化鎵二極管發(fā)藍(lán)光。因化學(xué)性質(zhì)又分有機(jī)發(fā)光二極管OLED和無機(jī)發(fā)光二極管LED發(fā)光二極管是一種常用的發(fā)光器件，通過電子與空穴復(fù)合釋放能量發(fā)光，它在照明領(lǐng)域應(yīng)用。[1]發(fā)光二極管可高效地將電能轉(zhuǎn)化為光能，在現(xiàn)代社會具有的用途，如照明、平板顯示、醫(yī)療器件等。[2]這種電子元件早在1962年出現(xiàn)，早期只能發(fā)出低光度的紅光，之后發(fā)展出其他單色光的版本，時(shí)至能發(fā)出的光已遍及可見光、紅外線及紫外線，光度也提高到相當(dāng)?shù)墓舛?。而用途也由初時(shí)作為指示燈、顯示板等；隨著技術(shù)的不斷進(jìn)步，發(fā)光二極管已被地應(yīng)用于顯示器和照明。上海先盛照明電器有限公司供應(yīng)led平面燈。 </p><p>跟著LED工業(yè)技能的進(jìn)步，LED軟燈帶環(huán)保，體積小，高可靠性的功能逐步從其它特性中凸顯出來。燈帶，是LED燈帶的簡稱，大部分人說的時(shí)分不習(xí)慣名詞太長，所以把前面的LED給省掉了，直接就叫燈帶。這樣燈帶的叫法也包含了曾經(jīng)許多大二線、大三線、圓二線等等的直接用線材聯(lián)接LED而不必FPC或PCB的老式燈帶，當(dāng)然也就包含了柔性燈帶和硬燈帶。現(xiàn)在在我國，LED照明工業(yè)有了快速展開，LED軟燈帶更是獲得了高度的注重，與傳統(tǒng)照明燈具相比較，LED軟燈帶以下幾個(gè)方面的長處相當(dāng)超卓：1.樸實(shí)的色彩LED軟燈條選用高亮度貼片LED為發(fā)光元件，因此具有了LED發(fā)光元件的長處，光色樸實(shí)、柔軟、無眩光。既可以作為裝飾用處，又可以兼做照明用處。2.柔軟性LED軟燈條選用十分柔軟的FPC為基板，可以任意彎折而不會折斷，易于成型，適宜各種廣告造型需求。3.發(fā)熱量小LED軟燈條的發(fā)光元件是LED，因?yàn)閱晤wLED的功率很低，一般為，因此發(fā)熱量不高?？梢宰鳛轸~缸里的裝飾照明，而不會產(chǎn)生許多熱量構(gòu)成水溫升高，影響觀賞魚的成長。4.超節(jié)能LED軟燈條1210的功率每米只有，5050的LED軟燈條每米功率為，相對于傳統(tǒng)照明及裝飾燈具而言，功率低了好幾倍，而作用卻好許多。LED，就選上海先盛照明電器有限公司，讓您滿意，歡迎您的來電！</p><div

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(shí)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(dòng)轉(zhuǎn)向頭燈、自動(dòng)遠(yuǎn)近光燈、LED流水轉(zhuǎn)向燈、主動(dòng)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(gè)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(dòng)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為您提供LED。河南官方LED現(xiàn)貨</p><p
