1、節(jié)能:同等功率的LED燈耗電*為白熾燈的10%，比日光燈還要節(jié)能，不發(fā)燙,防油,防塵.2、壽命長:LED燈珠的可以工作5萬小時，比日光燈和白熾燈都長。3、可調(diào)光:以前的調(diào)光器一直是針對白熾燈的，白熾燈調(diào)暗時光線.發(fā)紅;很難見到日光燈調(diào)光器，這是調(diào)光技術很多年沒有發(fā)展的主要原因;現(xiàn)在LED又可以調(diào)光了，并且無論是亮還是暗光都是同樣的顏**溫基本不變)，這一點明顯優(yōu)于白熾燈的調(diào)光。4可頻繁開關: LED的壽命是按點亮時算的，即便每秒鐘開關數(shù)千次也不影響LED壽命，在裝飾等需要頻繁亮滅的場合，LED燈有***優(yōu)勢。河南飛利浦led投光燈廠家一般來說，LED的人體靜電模式測試失效電壓不應低于2000V。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="text-indent:25px">在一些24小時連續(xù)工作的場地，例如地下停車場、24小時加班生產(chǎn)的工廠等地方。節(jié)電也是十分重要的。如上所述，- -根T8的LED日光燈大約可以節(jié)省20瓦電，一年下來就可以節(jié)省20x365x24/1000=175.2度電。假如以每度電0. 7元計算，那么一年下來，可以節(jié)省電費122.64元，兩年下來，就可以節(jié)省出這根LED日光燈的成本。以后所節(jié)省的電費就成為純收益了。所以現(xiàn)在國外有一種稱之為EMC (能源管理合同Energy ManagementContract)作法。就是由一家財團或銀行出資。替一個地下停車場或商場**安裝LED日光燈，但是要向業(yè)主收取所有節(jié)省下來的電費，協(xié)議有效期可能為5年。只要2年以后，就可以回收所有投資，第三年開始，所有節(jié)省下來的電費就變成是純收益了。這是一個十分有利的投資項目。國內(nèi)也開始有人這樣做了。更何況按照Haitz定律，LED的價格每十年將降低十倍!</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(shù)，造成數(shù)千萬美元的經(jīng)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(chǎn)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。首先我們可以先檢查一下，led燈珠是否因供電電源部分的原因而沒有正常工作導致燈珠不亮。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="福建防水投光燈批發(fā),投光燈"

style="text-indent:25px">一般金的導電率比較好，銀次之。在焊接工藝時，由于焊接實際上是形成合金的過程，這個合金本身就是良導體，所以焊接本身的可靠性是比較高的，除非是焊接不良。但是，連接器之間的連接，靠的是表面之間的接觸，所以容易導致接觸不良，更具體的原因分析如下。兩個金屬表面之間的接觸是否良好，主要取決于材料（不同金屬導電率不同)、接觸壓力、實際接觸面結(jié)。關于材料種類，上面已經(jīng)提到了，一般器件的鍍層材料，基本上都是由良導體做的，對接觸不良的影響不大。由于LED響應速度快,可以及早提醒司機剎車，減少汽車追尾事故，在發(fā)達國家。江西批發(fā)投光燈具批發(fā)</p><p
