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

style="text-indent:25px">接下來，我們聊聊為什么LED燈在關閉開關后還是發(fā)光:一、首先的原因就是我們的電路中火線直接進LED驅(qū)動器了，零線進開關，在關閉開關之后，致使切斷了零線，火線還一直和驅(qū)動器鏈接，加上了的燈工作的環(huán)境，LED在感應微弱的電流之后，就會觸發(fā)驅(qū)動器，也就是能使燈珠發(fā)光。二、在我們生活的空間內(nèi)，到處都是微弱的電波，我們只是習慣了這種電波，所以對人也沒有太大的影響，但是這對我們的LED驅(qū)動就不一樣了。三、再有就是可能存在燈具漏電的原因，經(jīng)個人多年來的經(jīng)驗判斷，有一些LED燈具在關閉電源開關之后，即使火線進開關，依然會亮，而且特別的亮，零線和火線顛倒順序之后，仍然會亮，這種原因的可能就很大。遼寧批發(fā)投光燈報價</p><p
