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，則產(chǎn)生高色溫的白光;相反，如果黃光占比多一點，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：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。LED，就選上海先盛照明電器有限公司，讓您滿意，期待您的光臨！</p><div

等于單位時間內(nèi)某一波段的輻射能量和該波段的相對視見率的乘積。由于人眼對不同波長光的相對視見率不同，所以不同波長光的輻射功率相等時，其光通量并不相等。光通量的單位為“流明”。光通量通常用Φ來表示，在理論上其單位相當(dāng)于電學(xué)單位瓦特，因視覺對此尚與光色有關(guān)。所以依標(biāo)準(zhǔn)光源及正常視力度量單位采用“流明”，符號：lm。由于人眼對不同波長的光的視見函數(shù)不同，所以不同的波長的光的輻射功率即使相等，其光通量并不相等。例如當(dāng)波長為5500的綠光與波長為6500?的紅光輻射功率相同時，前者的光通量為后者的10倍。光通量是每單位時間到達(dá)、離開或通過曲面的光強度；光通量是燈泡發(fā)出亮光的比率。簡單來說：是衡量光源輸出光多少的指標(biāo)。一個普通的燈泡，它輸出的所有光全部算在一起后就是這個燈泡光通量的具體數(shù)值?？梢园阉斫鉃椋阂粋€噴頭噴出了水，用一個氣球?qū)姵龅拿恳坏嗡佳b在里面，有多少裝多少，這就是光通量的含義。照度：照度的單位是勒克斯，符號表示為lx。它的定義是落在單位面積上光通量的大小，換而言之，也就是1平方米得到1流明的光叫做1個勒克斯。lx=lm/m^2同樣也可以用水來作一個比方：噴頭會噴很多水出來。北京正規(guī)LED功率</p></p><br
