種原因，電工接線時(shí)開(kāi)關(guān)控制了零線，或者電箱進(jìn)線時(shí)零火接反。開(kāi)關(guān)控制的是零線，火線依然和燈具連接著，就會(huì)發(fā)出微光。解決辦法:調(diào)整接線，讓開(kāi)關(guān)控制火線。2、雙控開(kāi)關(guān)出現(xiàn)錯(cuò)誤接法雙控開(kāi)關(guān)有好幾種接線方式，如果用了錯(cuò)誤的接法，也會(huì)關(guān)燈后微亮。解決方法:安裝正常的控制火線接法重新接線。3、開(kāi)關(guān)帶指示燈，用了電子類(lèi)開(kāi)關(guān) 開(kāi)關(guān)里面帶指示燈，關(guān)燈后會(huì)有輕微電流流過(guò)。如果燈具使用的是電子開(kāi)關(guān)，例如紅外，聲控，遙控開(kāi)關(guān)。也會(huì)出現(xiàn)關(guān)燈后發(fā)微光現(xiàn)象。<span style="display:none;"><span style="display:none;"><span
