style="text-indent:2em;"> led灯现在非常流行,慢慢的代替了白炽灯。亮度高低消耗,而且非常漂亮Ƒּ也多Q深的用L喜爱?</p> <p style="text-indent:2em;"> 但是随之而来的问题也不少Q比如LED用一D|间后变暗或者是灯光闪烁。今天我们就来分析一下造成q些故障的原因,Z教大家自己动手修复?</p> <p style="text-indent:2em;"> LED </p> <p style="text-indent:2em;"> LED灯现在市面上行的就2U,一U是恒流的一U是d的,相对来说恒流的比较稳定,有一个控制器Q电是E_输出的。阻容的相对来说l构单,只是做了降压处理Q得LED灯珠在正常的工作甉|内工作?</p> <p style="text-indent:2em;"> LED吊灯 </p> <p style="text-indent:2em;"> LED节能?</p> <p style="text-indent:2em;"> LED灯里面其实是很多个小灯珠Q它们一般是多个串联Q然后几个串联组合再q联?</p> <p style="text-indent:2em;"> q个是控制器 </p> <p style="text-indent:2em;"> 我们看一下上面的说明Q输入的?20伏的交流电,输出20--30伏的直流电,LED灯珠都是直供c?</p> <p style="text-indent:2em;"> 一QLED不亮 </p> <p style="text-indent:2em;"> 1Q根据上图控制器的介l,首先我们要检查控制器的输入端Q?20伏的供电甉|是否正常。然后再查输出端20--30伏的直流甉|是否输出正常。电源正常的情况下,我们再检查LED灯?</p> <p style="text-indent:2em;"> 用电W就可以?</p> <p style="text-indent:2em;"> 2Q?灯不亮大多都是控制器的问题Q所以如果检查输出端异常Q就更换控制器,如果动手能力强,也可以拆开自己查找原因自己动手修复?</p> <p style="text-indent:2em;"> 控制?</p> <p style="text-indent:2em;"> 二,LED发暗 </p> <p style="text-indent:2em;"> LED灯发暗一般是部分灯珠坏掉的情况,所以我们可以用万用表挨个检查灯珠的好坏Q当然也有可能是一l灯珠坏掉了。找出坏掉的灯珠Ҏ型号买对应的换上卛_Q这也需要一定的动手能力?</p> <p style="text-indent:2em;"> 万用?</p> <p style="text-indent:2em;"> 万用表的二极档位,用万用表的红黑表W接触灯珠的正负极,如果灯珠亮就是好的,不亮是坏掉了?</p> <p style="text-indent:2em;"> 三,LED灯微?</p> <p style="text-indent:2em;"> 一般质量差的LED灯有q种情况Q还有就是家里接灯不注意Q把开关灯C零线上。LED灯非常灵敏有微弱的电就可以点亮Q所有有的家庭用电子开关也会关了灯微亮Q不是哪一U情况引L微亮Q我们都可以用一个电器完美解决Q因为电器控制火线零线同时通断?</p> <p style="text-indent:2em;"> 用电器?l常开Ҏ制LED?</p></div><div class="meneame"><span
