What measures need to be taken for outdoor light pole LED display?
What measures need to be taken for outdoor light pole LED display? In the process of use, due to different environments, it is often affected by severe weather such as high temperature, typhoon, rainstorm, thunder and lightning. To make the display screen safe in severe weather, what precautions should we take?
1. Anti-high temperature
Outdoor light pole LED display usually has a large area, consumes a lot of power during the application process, and the corresponding heat dissipation is also large. In addition, the outside temperature is high. If the heat dissipation problem cannot be solved in time, it is likely to cause the circuit board. Problems such as heating and short circuit. In production, ensure that the display circuit board is in good condition, and try to choose a hollow design when designing the casing to help dissipate heat. When installing, according to the installation situation, keep the light pole LED display in a good ventilation condition, and add cooling equipment to the display when necessary, such as installing an air conditioner or fan inside to help the display dissipate heat.
2. Anti-typhoon
The installation position and installation method of outdoor light pole LED display are different, such as mosaic type, column type, hanging type, etc. Then in the typhoon season, in order to keep the screen of the outdoor light pole LED display from falling, there are strict requirements on the load-bearing steel frame structure of the display. The engineering unit must design and install in strict accordance with the standard of anti-typhoon level, and at the same time have a certain anti-seismic ability to ensure that the LED display of the light pole will not fall and cause casualties and other hazards.
3. Rainstorm protection
There is a lot of rain in the south, so the light pole LED display itself must have a high waterproof protection level to avoid rain erosion. In the outdoor use environment, the outdoor light pole LED display should reach the IP65 protection level, the module should be encapsulated by glue, the waterproof box should be selected, and the module and the box should be connected with a waterproof rubber ring.
4. Lightning protection
If the outdoor light pole LED display is not within the direct lightning protection range of nearby tall buildings, a lightning rod should be installed on or near the top of the steel structure of the display; The line is equipped with a signal lightning protection device. At the same time, the power supply system of the computer room is provided with 3-level lightning protection protection.
