也谈电子灯箱的防水问题

室外安装的电子灯箱可能遇到最严峻的问题不外乎是防水了，这个问题普遍被认为是一件费力又很难处理好的难题。我是这样做的，用热熔胶对灯逐个进行密封（也用过其他密封胶，因其成本高（是热熔胶的两倍）而最终放弃，边框接缝及与铝塑板间的缝隙用玻璃整体注一遍，并且在灯箱的底部钻几个孔，以防万一进水后可以从此处流出，不会因积满水致使原件产生短路，同时也起到一定的散热作用。只要做好外部防水，由于灯箱里面的温度较高，一般是不会出现潮湿现象的，喷漆这道工序可以免除（喷漆后形成的绝缘层会給将来检察坏灯造成很大困难的），防水做的好，灯角一般不会生锈。因此，防水这道工序一定要仔细认真，为了我们的质量，为了我们的信誉，为了我们自己少一点麻烦，一定要做好防水！

我跟二楼的做法差不多

学习了顶一下{:1_137:}

打胶维修不方便 用密封压条的话 估计要好的多  不过成本高了

热熔胶在夏天气温高就晒化了

厉害，学习了！！！好技术！！！

学习了。。。。。。。。。。。。。。。。。。。。。。

开眼界了！！！！！！！！！！！！！！！！！！！！！

好方法！发扬！！！！！！！！！！！！！

热熔胶不太妥当吧？用705 704好点。不过成本是点高
