Outdoor LED Screen is now the most widely used field. The area is huge and the display effect is perfect. At the same time, in order to better publicize the effect, it is usually installed on the roof, road and other open areas. Due to the large area and the open air, LED Screens are facing huge environmental challenges. Often face extreme weather such as strong winds, heavy rains, and hail. Therefore, the various protective indicators and protective equipment of the display are very important. The following introduces the indicators that outdoor LED Screens should have.
1. LED Screen IP protection level requirements
Outdoor LED Screen screens have a large installation area and are mostly installed in densely populated places. Therefore, special attention should be paid to the protection level of the display screen, especially in the southeast coastal areas where typhoons often log. Its design should consider many factors such as the solid foundation of the steel structure, wind load, waterproof, bulletproof, moisture-proof and so on. The protection level should be IP65 and above to extend the service life of the display and enhance the reliability.
2. LED Screen lightning protection standard
For lightning protection, the LED main body and shell should have good grounding measures, and the grounding form should be considered separately according to whether the display screen is installed independently or attached to the outer wall of the building.
At the same time, the integration of electronic components in outdoor LED Screen screens is high, and its sensitivity to interference has become higher and higher. In order to minimize electromagnetic interference, lightning protection devices should usually be installed on the display screen and buildings.
3. LED Screen high temperature heat dissipation
Outdoor LED Screen will generate a certain amount of heat when it is working. If the ambient temperature is too high and the heat dissipation is poor, the LED chip and related integrated circuits may not work properly or even be burned, which will make the LED Screen system unable to work normally, so usually outdoor LED The label display should be equipped with a cooling fan, especially for the display that needs to work in the subtropical and tropical regions with high temperature for a long time.
