How to deal with the harsh environment for outdoor LED display.advertising digital led screen wholesale

　　The LED display used as an outdoor advertisement is much higher than the general display environment. During the use of outdoor LED display, due to the different environment, it is often affected by high temperature, typhoon, heavy rain, and thunder and lightning. To make the display screen safe in bad weather, what preventive measures should we take?

　　1. Prevent high temperature

　　The outdoor LED display is usually large in area, consumes large power in the application process, and the corresponding heat emission heat is also high. In addition, if the external temperature is high, if the heat dissipation problem cannot be solved in time, it may cause the circuit board to heat the short circuit. And other issues. In the production, the state of the display screen is in good condition. Try to choose a hollow design when designing it as much as possible, which helps heat dissipation. When installing, the situation of the display of the display should be good according to the installation situation. When needed, the display screen is added to add heat dissipation equipment. It is like an air -conditioning machine or a fan to help the display heat dissipation.

　　Typhoon

　　The installation position of the outdoor LED display is different, and the installation method is different. Then in the typhoon season, in order to make the screen body of the outdoor LED display not drop, there are strict requirements for the load -bearing steel frame structure of the display screen. The engineering unit must be designed and installed strictly in accordance with the standards of the typhoon level. At the same time, it must also have a certain seismic resistance to ensure that the outdoor LED display will not drop the harm of casualties caused by personnel.

　　Third, anti -rainstorm

　　There are many rainwater weather in the south, so the LED display itself must have a high waterproof protection level in order not to encounter rainwater erosion. In the outdoor use environment, the outdoor LED display should reach the IP65 protection level. The module must be packaged by glue, selects a waterproof box, and connects the module to the box with a waterproof rubber ring.

　　Fourth, lightning protection

　　(1) Direct lightning protection: If the outdoor LED large screen is not in the scope of direct lightning protection of tall buildings nearby, a lightning rod is set on the top or nearby of the display steel structure;

　　(2) Induction lightning protection: Outdoor LED display power system does 1-2 level power supply lightning protection, signal lines installed signal lightning protection, at the same time, the power supply system of the machine room as a level 3 lightning protection protection, the signal out/entering room equipment side Add signal lightning protection;

　　(3) All LED display lines (power and signals) should be covered with buried land;

　　(4) The front end of the outdoor LED display screen and the floor -to -room grounding system shall meet the system requirements. Generally, the front -end ground resistance shall be less than 4 ohm, and the floor resistance of the computer room shall be less than or equal to 1 ohm.
