户外LED显示屏安装六个主意事项：
Six considerations for outdoor LED display installation:
1、显示屏及建筑物上安装避雷装置。
1. Lightning protection devices are installed on the display screen and buildings.
显示屏主体和外壳保持良好接地，接地电阻小于3欧姆，使雷电引起的大电流及时泄放；显示屏可能会受到雷电引起的强电强磁袭击。
The main body and shell of the display screen shall be well grounded, and the grounding resistance shall be less than 3 ohm, so that the large current caused by lightning can be discharged in time; the display screen may be attacked by strong current and strong magnetic field caused by lightning.
2、LED显示屏本身的防水措施
2. Waterproof measures for LED display screen
屏体及屏体与建筑的结合部必须严格防水防框格护坡模具 箱体护坡模具 华尔街铜牛 电阻柜 接地电阻柜 电缆保护接地箱 隔离墩模具 化粪池模具漏；屏体要有良好的排水措施，一旦发生积水能顺利排放；注意防水、防潮。显示屏安装在户外，经常日晒雨淋，风吹尘盖，工作环境恶劣。电子设备被淋湿或严重受潮会引起短路甚至起火，引发故障甚至火灾，造成损失；
The screen body and the joint between the screen body and the building must be strictly waterproof and leak proof; the screen body must have good drainage measures, once the ponding occurs, it can be discharged smoothly; pay attention to waterproof and moisture-proof. The display screen is installed outdoors, often in the sun and rain, wind and dust cover, and the working environment is bad. If the electronic equipment is wet or seriously affected with damp, it will cause short circuit or even fire, cause failure or even fire, and cause loss;
