Outdoor environment is the earliest and most common application area of LED display screens, with an area ranging from tens to hundreds of square meters.
In order to expand the audience’s field of vision and enhance the effect of outdoor advertising, they usually install in open areas such as rooftops.
LED displays with large areas and high positions are dazzling, but at the same time they have to face the test of harsh environments such as wind, frost, lightning, etc.
Strong winds and heavy rains test the protection level of LED displays
Generally, outdoor LED displays have a large installation area, and are mostly install in places with densely populated areas.
Therefore, should pay special attention to the protection level of the display. Especially in the southeastern coastal areas where typhoons often log in.
Its design must consider many factors such as the solid foundation of the steel structure, wind load, waterproof, dustproof, moisture-proof, etc.
The protection level must be IP65 or above to extend the service life of the display and enhance reliability.
Lightning protection and grounding to prevent leakage accidents
To provide lightning protection, the LED body and shell must have good grounding measures. And must consider the grounding form based on whether the display screen is set up independently or attached to the exterior wall of the building.
At the same time, the electronic components in outdoor LED displays are highly integrated. And their sensitivity requirements against interference are also getting higher and higher.
In order to minimize electromagnetic interference, lightning arresters should usually install on displays and buildings.
Provide ventilation and heat dissipation to resist high temperatures
Outdoor LED displays will generate a certain amount of heat when working.
If the ambient temperature is too high and the heat dissipation is poor, the LED chips and related integrated circuits may not work properly or even burn. It will make the LED display system unable to work properly.
Therefore, usually outdoor LED displays The label display screen should need a cooling fan or air conditioner. Especially for screens that need to work in high-temperature subtropical and tropical areas for a long time.
