style="text-indent:25px">一般的LED支架是經(jīng)過(guò)金屬?zèng)_壓再注塑所形成。LED作為發(fā)光二極管，需要對(duì)金屬內(nèi)表面進(jìn)行電鍍處理，銀作為良好的光反射材料，所以一般LED為電鍍銀表面處理。各種不同功率的LED采用的支架材料也不相同，小功率一般采用PPA、**率一般采用PCT、目前有一些大功率采用EMC材料制作。所有的塑膠材料都有吸水性，所以在LED燈珠生產(chǎn)過(guò)程中對(duì)支架需要進(jìn)行烘烤的除濕處理。電鍍層的處理是支架的關(guān)鍵點(diǎn)，鍍層厚度和質(zhì)量關(guān)系著后面的光通量、焊接性能。浙江三防燈服務(wù)至上大量外商都在求購(gòu)品質(zhì)好、服務(wù)好、價(jià)格好的面板燈產(chǎn)品和供應(yīng)商。</p><div

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?5、無(wú)紫外線(xiàn)，沒(méi)有蚊蟲(chóng)LED燈具不會(huì)產(chǎn)生紫外線(xiàn)，因此不會(huì)象傳統(tǒng)的燈具那樣，有很多蚊蟲(chóng)圍繞在燈源旁。室內(nèi)會(huì)變得更加干凈衛(wèi)生整潔。6、電壓可調(diào)80V- 245V 傳統(tǒng)的日光燈是通過(guò)整流器釋放的高電壓來(lái)點(diǎn)亮的，當(dāng)電壓降低時(shí)則無(wú)法點(diǎn)亮。而LED燈具在一定范圍的電壓之內(nèi)都能點(diǎn)亮，還能調(diào)整光亮度.7、節(jié)省能源，壽命更長(zhǎng)LED日光燈的耗電量是傳統(tǒng)日光燈的三分之一以下，壽命也是傳統(tǒng)日光燈的10倍，可以長(zhǎng)期使用而無(wú)需更換，減少人工費(fèi)用。更適合于難于更換的場(chǎng)合。</p><p style="text-indent:25px">通常把亮度(光通量)降到一半的時(shí)間稱(chēng)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(wàn)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(shuō)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(yú)”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(guò)以下的計(jì)算可以看出采用銅及鋼支架的不同。LED面板燈由于光線(xiàn)柔和、外形美觀，已經(jīng)廣為歐美客商青睞。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

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。一般LED面板燈的安裝可鑲嵌于天花板、墻壁和安裝體表面。浙江三防燈服務(wù)至上</p><p
