4W，也就是鐵芯電感損耗了6.4W,效率降低為85%，大多數國產的鐵芯電感功耗在10W以上功率因素低于0.512，安徽led戶外投光燈led。而LED的電源效率通常高達90%，--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，安徽led戶外投光燈led。在點間距不變的前提下，LED器件尺寸增大，能夠增加顯示面積，減少顆粒感。安徽led戶外投光燈led</p><div

style="text-indent:25px">而熒光燈都是采用易碎的玻璃作為外殼，一旦玻璃破碎，其中的汞就會馬上就會蒸發(fā)到空氣中，瞬間可使周圍空氣中的汞濃度達到10-20毫克/立方米，超過國家規(guī)定的1000- 2000倍。而汞是一種對人體十分有害的有毒物質，汞蒸氣達0. 04至3毫克時會使人在2至3月內慢性中毒，達1. 2至8.5毫克時會誘發(fā)急性汞中毒，如若其量達到20毫克，會直接導致動物死亡。而1mg的汞就足以污染5454.5公斤的飲用水，使之達不到飲用標準。而LED日光燈中不含任何有毒物質，是一種完全綠色環(huán)保無污染光源。<span style="display:none;"><span style="display:none;"><span

style="text-indent:25px">色溫范圍廣，幾乎可以提供任意色溫，而且還可以提供紅綠藍以至任何一種顏色的燈光。顯指高，白熾燈的顯色指數為95，熒光燈為65-80，而LED日光燈則可以>80。沒有紫外線輻射。非玻璃制品，不易破損，耐沖擊，耐振動。10.外置隔離電源的LED日光燈，在燈管兩端都接觸不到市電高壓，只有低于36V的直流安全電壓，不存在觸電的危險，完全是一種安全的燈具。目前LED日光燈***的缺點就是價格高。不過盡管目前LED日光燈的價格大約是熒光燈的十倍左右，如果聯(lián)系到它的壽命、節(jié)電和無污染來看，仍然是合算的。因為如果和壽命為5,000小時的熒光燈相比，那么壽命為5萬小時的LED日光燈就已經值得.</p><p style="text-indent:25px">靜電是一種危害極大的魔鬼，全世界因為靜電損壞的電子元器件不計其數，造成數千萬美元的經濟損失。所以防止靜電損壞電子元器件，是電子行業(yè)一項很重要的工作，LED封裝、應用的企業(yè)千萬不要掉以輕心。任何一個環(huán)節(jié)出問題，都將造成對LED的損害，使LED性能變壞甚至失效。我們知道人體（ESD）靜電可以達到三千伏左右，足可以將LED芯片擊穿損壞，在LED封裝生產線，各類設備的接地電阻是否符合要求，這也是很重要的，一般要求接地電阻為4歐姆，有些要求高的場合其接地電阻甚至要達到≤2歐姆。LED在顯示屏整體成本中所占比例比較大，從30%至70%不等。</p><div

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
