LED靠電子在能帶間的躍遷來發(fā)光，它光譜單一，不含紅外部分，不同于傳統(tǒng)的固體熱致發(fā)光光源的白熾燈。因此將LED稱作“冷”光源，其實(shí)LED芯片*能將不到10%的電能轉(zhuǎn)化為光能，其余90%轉(zhuǎn)化為熱能。而且這些熱能的大部分只能靠傳導(dǎo)散發(fā)出去。因此，良好的散熱設(shè)計(jì)對(duì)LED的正常使用非常重要。2、LED對(duì)工作溫度要求嚴(yán) LED的芯片對(duì)溫度異常敏感，這也是半導(dǎo)體的共性。從下列的圖及表格中可以看出LED的使用壽命與結(jié)溫(Tj)關(guān)系。福建三防燈批發(fā)廠家經(jīng)過幾年對(duì)市場(chǎng)的調(diào)研和觀察，楊遇維認(rèn)為，現(xiàn)在的樓層高度決定了光線柔和度。</p><div style="width:100%;text-align:

style="text-indent:25px">LED日光燈相對(duì)傳統(tǒng)日光有那些優(yōu)化點(diǎn)呢?2、高效轉(zhuǎn)換，減少發(fā)熱傳統(tǒng)燈具會(huì)產(chǎn)生大量的熱能，而LED燈具則是把電能全都轉(zhuǎn)換為光能，不會(huì)造成能源的浪費(fèi)。而且對(duì)文件，衣物也不會(huì)產(chǎn)生退色現(xiàn)象。3、清靜舒適，沒有噪音LED燈具不會(huì)產(chǎn)生噪音，對(duì)于使用精密電子儀器的場(chǎng)合為上佳之<span style="display:none;"></span><span style="display:none;"></span>選。適合于圖書館，辦公室之類的場(chǎng)合。4、光線柔和，保護(hù)眼睛傳統(tǒng)的日光燈使用的是交流電，所以每秒鐘會(huì)產(chǎn)生100-120次的頻閃。LED 燈具是把交流電直接轉(zhuǎn)換為直流電，不會(huì)產(chǎn)生閃爍現(xiàn)象，保護(hù)眼睛。飛利浦LED燈帶LS155 G2低壓燈帶低壓工作，**發(fā)熱，安全無憂，長效使用。批發(fā)三防燈客戶至上</p><p style="text-indent:25px">一般公司沒有完整的開發(fā)團(tuán)隊(duì)和足夠的開發(fā)經(jīng)驗(yàn)以及后續(xù)的供應(yīng)鏈管理能力，很難真正開發(fā)成功。批發(fā)三防燈客戶至上</p><p style="text-indent:25px">通常把亮度(光通量)降到一半的時(shí)間稱為半衰期，行業(yè)內(nèi)將LED的使用壽命定義為它的半衰期。LED的半衰期同P-N結(jié)(Tj點(diǎn))結(jié)點(diǎn)的溫度有如下函數(shù)關(guān)系。通常講的LED的使用壽命十萬小時(shí)是指P-N結(jié)溫在25°C時(shí)的半衰期。目前市面上絕大部分LED的使用結(jié)溫(Tj)都在95°C以上。也就是說它的使用壽命只有780小時(shí)左右。3、散熱經(jīng)實(shí)際測(cè)試及經(jīng)濟(jì)性等全方面的衡量，建議LED的結(jié)溫應(yīng)控制在55°C以下，假設(shè)天氣溫度為35°C要達(dá)到結(jié)溫55°C以下，則在自然對(duì)流的情況下，每1W需要100cm2的外殼散熱.面積，且芯片與散熱板間熱阻每瓦Re< 10k/w。4、用鋼支架取代銅支架的不利影響現(xiàn)在市面.上99%的LED為節(jié)省制造成本使用了鋼支架，采用鋼支架LED的壽命只有使用銅支架壽命約1/4，因此建議一定要采用銅支架，采用銅支架的“食人魚”顆粒就是很好例子。LED的結(jié)構(gòu)，LED 結(jié)點(diǎn)的熱量主要依靠陰極腳導(dǎo)出、陰極腳的尺寸。通過以下的計(jì)算可以看出采用銅及鋼支架的不同。批發(fā)三防燈客戶至上</p><p
