Outdoor led advertising screens are much harsher than indoor environments. First of all, outdoor led advertising screens are exposed to wind and rain, and they have 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 must be done Good protection measures can achieve the ideal life. Outdoor scenes are the earliest and most common application fields of LED advertising screens. The area ranges from tens to hundreds of square meters. In order to expand the audience's field of vision and enhance the effect of outdoor advertising, it is usually installed in high open areas such as roofs. The so-called "big tree attracts the wind", the LED advertising screen with large area and high position is dazzling, but at the same time it has to face the test of harsh scenes such as wind, frost, lightning and so on.
Lightning protection grounding, to prevent leakage accidents, good lightning protection, LED main body and shell should have good grounding measures, and consider the grounding form according to whether the display screen is installed independently or attached to the outer wall of the building. At the same time, the electronic components in outdoor LED advertising screens are highly integrated, and their anti-interference sensitivity requirements are getting higher and higher. In order to minimize electromagnetic interference, lightning protection devices should usually be installed on the display screen and buildings. Storms are raging to test the protection level of LED advertising screens. Usually, outdoor LED advertising screens are installed in a large area, and most of them are 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 land.
Its design should consider many factors such as solid foundation of the steel structure, wind load, waterproof, dustproof, moisture-proof, etc., and the protection level should be IP65 or above to prolong the service life of the display screen and enhance reliability. Do a good job of ventilation and heat dissipation to resist high temperatures. Outdoor LED billboards will generate a certain amount of heat when they work. 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 used. Normal work, so usually outdoor LED advertising screens should be equipped with cooling fans or air conditioners, especially for screens that need to work in subtropical and tropical areas with high temperature for a long time.
