style="text-indent:25px">度發(fā)光的，而在反方向發(fā)出的光就沒(méi)有什么用處。所以熒光燈通常采用一個(gè)白色的燈罩，可以把相當(dāng)一部分的反向光反射回來(lái)，一般來(lái)說(shuō)，熒光燈的燈具效率大約只有70%。而LED日光燈則是120度發(fā)光的，所以全部光都是有效光。雖然有時(shí)候也會(huì)覺(jué)得120度發(fā)光角度窄了一點(diǎn)，不過(guò)大多數(shù)情況下還是夠用的。而且這個(gè)發(fā)光角度也是可以根據(jù)需要來(lái)加以調(diào)整的。前面提到Philips的T8熒光燈的發(fā)光效率為721m/W，36W的熒光燈一共發(fā)出2592流明，但是燈具效率只有70%，所以有效的流明數(shù)為1814.4浙江戶外投光燈具批發(fā)以防止LED因內(nèi)部芯片受潮造成漏電引起LED燈珠不亮。</p><div

style="text-indent:25px">接下來(lái)，我們聊聊為什么LED燈在關(guān)閉開(kāi)關(guān)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(jìn)LED驅(qū)動(dòng)器了，零線進(jìn)開(kāi)關(guān)，在關(guān)閉開(kāi)關(guān)之后，致使切斷了零線，火線還一直和驅(qū)動(dòng)器鏈接，加上了的燈工作的環(huán)境，LED在感應(yīng)微弱的電流之后，就會(huì)觸發(fā)驅(qū)動(dòng)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(xí)慣了這種電波，所以對(duì)人也沒(méi)有太大的影響，但是這對(duì)我們的LED驅(qū)動(dòng)就不一樣了。三、再有就是可能存在燈具漏電的原因，經(jīng)個(gè)人多年來(lái)的經(jīng)驗(yàn)判斷，有一些LED燈具在關(guān)閉電源開(kāi)關(guān)之后，即使火線進(jìn)開(kāi)關(guān)，依然會(huì)亮，而且特別的亮，零線和火線顛倒順序之后，仍然會(huì)亮，這種原因的可能就很大。</p><p 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(gè)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(zhuǎn)化為熱量散發(fā)出來(lái);如果是裝在燈管內(nèi)就會(huì)產(chǎn)生一個(gè)很高的溫度，再加.上我們LED的一個(gè)光效比所散發(fā)熱.量，就會(huì)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(huì)隨溫度的上升而縮短.效率高，轉(zhuǎn)化成光的效率就高，而且電源和燈管的發(fā)熱就會(huì)減少，相當(dāng)于省電，產(chǎn)品性能和壽命會(huì)提高。所以說(shuō)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(gè)指標(biāo)有時(shí)會(huì)故藍(lán)、綠色LED在顯示屏設(shè)計(jì)時(shí)盡量不要用到20mA電流，比較好只用70%至80%的額定電流。</p><div
