解決方法2:在燈具進(jìn)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(fù)載不平衡，線路太長，線徑細(xì)，或者零線電流過大，都會造成零線帶電。解決辦法:重新進(jìn)行零線接地或進(jìn)行低壓改造。如存在不正確操作引起燈珠不亮，則重新焊接led燈珠一般即可解決。</p><div
