style="text-indent:25px">接下來，我們聊聊為什么LED燈在關(guān)閉開關(guān)后還是發(fā)光:一、首先的原因就是我們的電路中火線直接進LED驅(qū)動器了，零線進開關(guān)，在關(guān)閉開關(guān)之后，致使切斷了零線，火線還一直和驅(qū)動器鏈接，加上了的燈工作的環(huán)境，LED在感應(yīng)微弱的電流之后，安徽投光燈廠家，就會觸發(fā)驅(qū)動器，也就是能使燈珠發(fā)光。二、在我們生活的空間內(nèi)，到處都是微弱的電波，我們只是習(xí)慣了這種電波，所以對人也沒有太大的影響，安徽投光燈廠家，但是這對我們的LED驅(qū)動就不一樣了。三、再有就是可能存在燈具漏電的原因，經(jīng)個人多年來的經(jīng)驗判斷，有一些LED燈具在關(guān)閉電源開關(guān)之后，即使火線進開關(guān)，安徽投光燈廠家，依然會亮，而且特別的亮，零線和火線顛倒順序之后，仍然會亮，這種原因的可能就很大。使用LED制造的**后置高位剎車燈已成為汽車的標(biāo)準(zhǔn)件.安徽投光燈廠家</p><div

投光燈是指定被照面上的照度高于周圍環(huán)境的燈具。又稱聚光燈。通常，它能夠瞄準(zhǔn)任何方向，并具備不受氣候條件影響的結(jié)構(gòu)。主要用于大面積作業(yè)場礦、建筑物輪廓、體育場、立交橋、紀(jì)念碑、公園和花壇等。因此，幾乎所有室外使用的大面積照明燈具都可看作投光燈。投光燈的出射光束角度有寬有窄，變化范圍在0°～180°之間，其中光束特別窄的稱為探照燈。投光燈由光學(xué)部件、機械部件和電氣部件3部分組成。光學(xué)部件主要是反射器和限制光線投光燈的遮光格片。機械部件主要是外殼，以及固定和調(diào)整光源位置的調(diào)焦機構(gòu)，固定燈具的支架、基座和帶有角度指示的調(diào)整燈具光束投射方向的零件。對絕大部分為密閉式的投光燈，機械部件還有保護玻璃及各種密封圈。根據(jù)使用環(huán)境的需要，有的還帶有金屬網(wǎng)罩。性能良好的投光燈還配有空氣過濾器。電氣部件主要是鎮(zhèn)流器、電容器、觸發(fā)器（根據(jù)光源需要而設(shè)）等。河北投光燈鎮(zhèn)流器視角的圓形LED就夠了。</p><div

解決方法2:在燈具進線部位并聯(lián)500K電阻。但是此方法對技術(shù)要求高，非專業(yè)人員不容易操作。并且對零線帶電，或者貼片漏電引起的發(fā)微光無效。4、非隔離驅(qū)動，光源貼片和基板漏電很多燈具出于成本考慮都是用劣質(zhì)阻容降壓驅(qū)動，或者光源貼片質(zhì)量差，存在貼片和基板漏電?；甯层~和基板電容效應(yīng)，也會引起漏光。這就是為什么一個房間里里，燈具有的亮有的不亮的原因。解決辦法:換燈具，拼運氣。 5、零線帶電了，其實零線帶電才是關(guān)燈后發(fā)光的zui根本原因。如果開關(guān)控制的是火線，使用的是普通墻壁開關(guān)，還是發(fā)光，就是零線帶電了。零線帶電是很普遍的現(xiàn)象。如零線接地不好，變壓器三相負載不平衡，線路太長，線徑細，或者零線電流過大，都會造成零線帶電。解決辦法:重新進行零線接地或進行低壓改造。</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(dǎo)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。這樣進行正確的解決就可以了，希望我們的介紹可以幫助大家。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="安徽投光燈廠家,投光燈"

style="text-indent:25px">隔離/非隔離:一般隔離電源如做成15W，放在LED燈管內(nèi)，其變壓器體積很大，很難放進去。尤其對T6/T8燈管，幾乎不可能的，所以隔離的一般只能做到10W,超過10W的很少，并且價格很貴。所以，隔離的性價比不高，一般是非隔離的占主流較多，體積可以做得更小，zui小可以做到高8毫米，實際上，非隔離的安全措施做好了，是不存在問題的。電源效率與功率因素:功率因素是有功功率和總功率的比值(C，剩下的無功功率在電網(wǎng)中相互轉(zhuǎn)化，用戶的電表不會計量無功功率的，對用戶的電表沒任何影響，只是供電局收不到用戶無功功率的錢。LED燈珠對LED顯示屏的影響有哪些？湖北批發(fā)投光燈具</p><p
