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(shù)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(guān): LED的壽命是按點亮時算的，即便每秒鐘開關(guān)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。飛利浦明欣LED投光燈G2 BVP150防腐蝕粉末涂層，確保產(chǎn)品可以在戶外應(yīng)用。更先進的LED科技。</p><div style="width:100%;text-align: center;"><img

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!飛利浦LED若欣吸頂燈新款與舊款相比同等瓦數(shù)更亮，光效更柔和和均勻，厚度更薄，節(jié)省空間簡約別致。浙江1688投光燈廠家</p><p

style="text-indent:25px">多路恒流輸出供電方式，在成本和性能方面會較好。也許是以后的主流方向。5.浪涌保護LED抗浪涌的能力是比較差的，特別是抗反向電壓能力。加強這方面的保護也很重要。有些LED燈裝在戶外，如LED路燈。由于電網(wǎng)負載的啟甩和雷擊的感應(yīng)，從電網(wǎng)系統(tǒng)會侵入各種浪涌，有些浪涌會導致LED的損壞。因此LED驅(qū)動電源要有抑制浪涌的侵入，保護LED不被損壞的能力。6. 保護功能電源除了常規(guī)的保護功能外，zui好在恒流輸出中增加LED溫度負反饋，防止LED溫度過高。福建戶外投光燈鎮(zhèn)流器</p><p
