基本的發(fā)光原理并沒有太大的變化：在兩層半導(dǎo)體之間，電子和與空穴碰撞復(fù)合并于發(fā)光層產(chǎn)生了藍(lán)色的光子。所產(chǎn)生的藍(lán)光有一部分會直接穿過熒光涂層直接發(fā)射出去;剩下的一部分會打在熒光涂層上并與之作用產(chǎn)生黃色光子。藍(lán)色光子與黃色光子共同作用（混合）就產(chǎn)生了白光。上圖是一個LED的光譜曲線：可以看到藍(lán)光峰值位于波長450納米處，而之后稍微低矮一點(diǎn)的峰值是由熒光粉吸收藍(lán)光后所產(chǎn)生的黃光的峰值。如果藍(lán)光的占比多一點(diǎn)，則產(chǎn)生高色溫的白光;相反，如果黃光占比多一點(diǎn)，則產(chǎn)生色溫較低的白光。所以：白光的熒光粉偏淺黃，中性光的熒光粉偏黃，而暖光的熒光粉橙色，高顯色的暖光更偏紅。LED燈的發(fā)光原理baijiahao./s?id=68700610&wfr=spider&for=pcLED燈珠的封裝形式引腳插入行（DIP)俗稱：草帽燈珠，有兩個插件腳。是簡單，也便宜的燈珠形式。特點(diǎn)：安全性好，性能穩(wěn)定，在低電壓的情況下就可以發(fā)光，并且低損耗、效能高、壽命長。不過一般功率偏低，而且應(yīng)用范圍一般在于車燈，指示燈，顯示屏里面。這些功率一般在。中小功率表面貼裝性（SMD)這種燈珠光源是將發(fā)光二極管焊接在電路板表面，而不是穿過電路板。它的體積小，這類燈珠的型號有很多，常用的有2835。四川官方LED用途上海先盛照明電器有限公司致力于提供LED，竭誠為您服務(wù)。</p><div
