鹵素射燈發(fā)熱量雖低于220V的射燈，但又有因所配變壓器功率不足等原因，其亮度達不到標稱值。用LED射燈，不用變壓器也可以長時間工作缺點:開發(fā)成本較高。價格相對傳統(tǒng)燈來說價格較貴!但是LED作為--種新型的綠色光源產(chǎn)品，必然是未來發(fā)展的趨勢，21世紀將進入以LED為**的新型照明光源時代。</p><p

2)、支架的組成:支架由支架素材經(jīng)過電鍍而形成，由里到外是素材、銅、鎳、銅、銀這五層所組成;3)、支架的種類:帶杯支架做聚光型，平頭支架做大角度散光型的1、直插式A、2002 杯/平頭:此種支架一般做對角度、亮度要求不是很高的材料，比其他支架要短10mm左右。Pin 間距為2. 28mm;B、2003杯/平頭:一般用來做φ 5以上的Lamp , 外露pin長為+29mm、-27mm，Pin 間距為2.54mm;C、2004杯/平頭:用來做用來做φ 3左右的Lamp， Pin長及間距同2003支架;D、2006:兩極均為平頭型，用來做閃爍、兩極均為平頭型，用來做閃爍Lamp，固IC，焊多條線;F、2009:用來做雙色的Lamp,杯內(nèi)可固兩顆，三支pin腳控制極性;G、2009-8/3009:用來做三色的Lamp，杯內(nèi)可固三顆晶片，四支pin腳。這樣，紅、綠、藍三種顏色LED的角度一致性將影響不同角度白平衡一致性，直接影響顯示屏視頻顏色的保真度。甘肅批發(fā)投光燈廠家</p><p
