style="text-indent:25px">LED發(fā)光強(qiáng)度是表征它在某個方向上的發(fā)光強(qiáng)弱，由于LED在不同的空間角度光強(qiáng)相差很多，隨之而來我們研究了LED的光強(qiáng)分布特性。這個參數(shù)實際意義很大，直接影響到LED顯示裝置的較小觀察角度。比如體育場館的LED大型彩色顯示屏，如果選用的LED單管分布范圍很窄，那么面對顯示屏處于較大角度的觀眾將看到失真的圖像。而且交通標(biāo)志燈也要求較大范圍的人能識別。對于LED的光譜特性我們主要看它的單色性是否優(yōu)良，而且要注意到紅、黃、藍(lán)、綠、白色LED等主要的顏色是否**。因為在許多場合下，比如交通信號燈對顏色就要求比較嚴(yán)格，不過據(jù)觀察我國的一些LED信號燈中綠色發(fā)藍(lán)，紅色的為深紅，從這個現(xiàn)象來看我們對LED的光譜特性進(jìn)行專門研究是非常必要而且很有意義的。四川光頭強(qiáng)LEDLED五大原物料分別是指：晶片，支架，銀膠，金線，環(huán)氧樹脂。</p><div
