style="text-indent:25px">流明，而LED的發(fā)光效率已經(jīng)超過130lm/W，假定為100lm/W，那么18W就可以達到1800流明，也就是只要熒光燈一半的功率就可以有相同的亮度。而且LED的發(fā)光效率還在逐年升高。3.電源效率高因為所有燈具除白熾燈以外都是需要有專門的電源供電的，電源的效率也就影響了整個燈具的效率。下面以Philips公司的36WT8熒光燈為例。它的額定輸出功率為36W，但是由于接入了電感鎮(zhèn)流器，實測輸入功率為42. 4W，吉林1688投光燈led，也就是鐵芯電感損耗了6.4W,效率降低為85%，大多數(shù)國產(chǎn)的鐵芯電感功耗在10W以上功率因素低于0.512。而LED的電源效率通常高達90%，吉林1688投光燈led，--個18W的LED日光燈只要20W的輸入功率。功率因素也可以達到0.9以上。如果是，吉林1688投光燈led，可檢查電源線路，一般電源正常的話，led頂燈接上去上面的指標燈會亮的。吉林1688投光燈led</p><div

style="text-indent:25px">而效率(y則是輸出功率和輸入功率的比值，即輸出功率(輸出LED的電壓*輸出電流/輸入功率，這個參數(shù)尤為重要，涉及到產(chǎn)品和用戶的利益，如果效率低就意味著輸入功率有很大一部分轉化為熱量散發(fā)出來;如果是裝在燈管內(nèi)就會產(chǎn)生一個很高的溫度，再加.上我們LED的一個光效比所散發(fā)熱.量，就會疊加產(chǎn)生更高的溫度。而我們的電源內(nèi)部所有電子零件的壽命都會隨溫度的上升而縮短.效率高，轉化成光的效率就高，而且電源和燈管的發(fā)熱就會減少，相當于省電，產(chǎn)品性能和壽命會提高。所以說效率是決定電源壽命zui根本的因數(shù)，效率不能太低，否則消耗在電源上的熱量太大。一般在0.8-0.9以上就可以了。功率因素，效率這兩個指標有時會吉林白光投光燈鎮(zhèn)流器5mm

style="text-indent:25px">在1999年開始引入了可以在1瓦電力輸入下連續(xù)使用的商業(yè)品級LED。這些LED都以特大的半導體芯片來處理高電能輸入的問題，而那半導體芯片都是固定在金屬鐵片上，以助散熱。在2002年，在市場上開始有5瓦的LED的出現(xiàn)，而其效率大約是每瓦18至22流明。2003年九月，Cree,Inc. 公司展示了其新款的藍光LED，在20毫安下達到35%的照明效率。他們亦制造了一款達65流明每瓦的白光LED商品，這是當時市場上zui光的白光LED。在2005年他們展示了一款白光LED原型,在350毫安工作環(huán)境下，創(chuàng)下了每瓦70流明的記錄性效率。今<span

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。垂直視角50°;的橢圓LED，戶內(nèi)顯示屏則選用水平垂直均為120°;</p><div
