Outdoor LED display is the most widely used field of LED display. The area is huge and the display effect is shocking. At the same time, in order to better publicize the effect, usually the top of Yu building, road and other empty and unobstructed areas are installed. Due to its large area and open-air conditions, LED displays face huge environmental challenges. Often face extreme weather such as strong winds, heavy rain and hail. Therefore, the display indicators and protective equipment are very important. The following introduces the indicators that outdoor LED module should have.
LED Display IP Protection Level Requirements
Outdoor LED display screens usually have a large installation area, and most of them are installed in densely populated places, so pay special attention to the protection level of the display screens, especially in the southeast coastal areas where typhoons often log in. Its design should consider the solid foundation of the steel structure, wind load, waterproof, dustproof, moisture-proof and many other factors, and the protection level should be IP6IP5 or above, to extend the service life of the display and enhance reliability.
LED Display Lightning Protection Standards
For lightning protection, the LED main body and the housing must have good grounding measures, and the grounding forms should be considered separately according to whether the display screen is independently installed or attached to the exterior wall of the building. At the same time, the outdoor LED display has a high degree of integration of electronic components, and its sensitivity to anti-interference is also increasing. In order to minimize electromagnetic interference, LED lightning protection devices should usually be installed on the display and buildings.
LED Display Heat Dissipation
Outdoor LED display will generate some heat when working. If the ambient temperature is too high and the heat dissipation is not good, the LED chip and related integrated circuits may work abnormally or even be burned, so that the Novastar LED display system cannot work normally. The label display should be equipped with a cooling fan or air conditioner, especially for screens that need to work in high temperature subtropical and tropical regions for a long time.
