style="text-indent:25px">一般金的導(dǎo)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(dǎo)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(dǎo)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(dǎo)電率不同)、接觸壓力、實際接觸面結(jié)。關(guān)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(dǎo)體做的，對接觸不良的影響不大。安徽防水投光燈批發(fā)廠家***的LED器件能夠很好地控制亮度衰減幅度。</p><div

style="text-indent:25px">一般都要用串、并聯(lián)來聯(lián)接，來適應(yīng)不同的工作電壓，串聯(lián)的LED燈越多影響越大，只要其中有一個LED燈內(nèi)部連線開路，將造成該串聯(lián)電路的整串LED燈不亮，可見這種情況比第一種情況要嚴(yán)重的多。LED死燈是影響產(chǎn)品質(zhì)量、可靠性的關(guān)健，如何減少和杜絕死燈，提高產(chǎn)品質(zhì)量和可靠性，是封裝、應(yīng)用企業(yè)需要解決的關(guān)鍵問題。下面是對造成死燈的一些原因作一些分析探討1、靜電對LED芯片造成損傷，使LED芯片的PN結(jié)失效，漏電流增大，變成一個電阻</p><p style="text-indent:25px">LED日光燈優(yōu)缺點點評 zui近以來，led日光燈成為zui早進(jìn)入室內(nèi)的LED燈具之一，因為它相對于熒光燈來說具有很多優(yōu)點。一．優(yōu)點相對于熒光燈來說，led日光燈具有**優(yōu)點:1.發(fā)光效率高:熒光燈的發(fā)光效率大約是55-80 lm/W (Philips公司T8熒光燈的發(fā)光效率為72lm/W)，而LED的發(fā)光效率在100 lm/W以上，zui近Cree公司的XLampXP-G的發(fā)光效率已經(jīng)到130流明/W，而且以后還會不斷提升。二者之差現(xiàn)在已經(jīng)將近一倍。而以后有可能達(dá)到3倍以上。2.燈具效率高:燈具的效率主要是指有效光效，因為熒光燈是360對于LED顯示屏的品質(zhì)影響起著主導(dǎo)作用。</p><div
