現(xiàn)在LED燈具的光效=。疑問：不同燈珠廠給出的參數(shù)表格不一致，難以按照以上公式計算；燈珠模組排列是否會導(dǎo)致光效衰減？如何知道燈具外殼溫度，推算出Tj溫度？LED燈具光效與LED光效的區(qū)別（精）-百度文庫在線互動式文檔分享平臺，在這里，您可以和千萬網(wǎng)友分享自己手中的文檔，全文閱讀其他用戶的文檔，同時，也可以利用分享文檔獲取的積分下載文檔wenku./view/LED燈珠的晶片大小與光效LED能承受的電流，取決于：晶片大小，一般用mil（1mil=1/1000inch=)稱呼大小，舉例：SMD2835的三安芯片，一般做做10x30mil或者17x34mil。LED的燈珠使用，需要留有余量，一般需要比額定電流低20%左右。LED燈珠的評價一般按光效來計算，光通量/功率=光效，越高越貴。現(xiàn)在的LED光效一般都能達(dá)到100-150lm/W,甚至達(dá)到190lm/W。LED燈珠的光效，其實是跟驅(qū)動電流一定程度上成反比，意思是驅(qū)動電流約靠近額定電流，其實光效是越低的。一般燈珠廠標(biāo)注的高光效，都是在比較低的額定電流下測定的。燈珠色溫.，相關(guān)色溫ColorTemperature:色溫是照明光學(xué)中用于定義光源顏色的一個物理量。即把某個黑體加熱到一個溫度，其發(fā)射的光的顏色與某個光源所發(fā)射的光的顏色相同時。</p><p> 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。上海先盛照明電器有限公司是一家專業(yè)提供LED的公司，歡迎新老客戶來電！</p><div
