Outdoor led advertising screens are much harsher than the indoor environment. First of all, it is exposed to wind and rain outside, and it has to withstand the risk of sun exposure. Therefore, outdoor led advertising screens have strict requirements for waterproof and high temperature resistance. Outdoor led advertising screens Protective measures must be taken to achieve the desired lifespan.
Outdoor scenes are the earliest and most common application areas of LED advertising screens, with areas ranging from tens to hundreds of square meters. In order to expand the audience's vision and strengthen the effect of outdoor advertising, they are usually installed in open areas such as the roof. The so-called "big tree attracts the wind", the LED advertising screen with a large area and a high position is dazzling, but at the same time it has to face the test of harsh scenes such as wind, frost and lightning.
Lightning protection and grounding to prevent leakage accidents, good lightning protection, LED main body and shell should have good grounding measures, and the grounding form should be considered according to whether the display screen is set independently or attached to the outer wall of the building. At the same time, the integration of electronic components in outdoor LED advertising screens is high, and its sensitivity to interference is also getting higher and higher. In order to minimize electromagnetic interference, lightning protection devices should be installed on the display screen and buildings.
Severe storms test the protection level of LED advertising screens. Usually, outdoor LED advertising screens have a large installation area, and most of them are installed in places with denser people. Therefore, special attention should be paid to the protection level of the display screen, especially in the southeast coastal areas where typhoons often hit. Its design should consider the solid foundation of the steel structure, wind load, waterproof, dust-proof, moisture-proof and many other factors, and the protection level should be IP65 and above to prolong the service life of the display screen and enhance the reliability. Do a good job of ventilation and heat dissipation to resist high temperature. Outdoor led billboards will generate a certain amount of heat when working. If the scene 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, so that the LED display system cannot be Work normally, so usually outdoor LED advertising screens need to be equipped with cooling fans or air conditioners, especially for screens that need to work in subtropical and tropical areas with high temperatures for a long time.
