Outdoor led advertising screen for environmental factors
The outdoor led advertising screen is much worse than the indoor environment. The first is the outdoor wind and rain, and the risk of sun exposure. Therefore, the outdoor led advertising screen has strict requirements for waterproofing and high temperature protection. The outdoor led advertising screen must be done. Good protection measures can achieve the desired life.
The outdoor scene is the earliest and most common application area of led advertising screens, ranging from tens to hundreds of square meters. In order to expand the audience's vision and enhance the effect of outdoor advertising, it is usually installed in the open space of the top of the building. The so-called "big tree", 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 and lightning.
Lightning protection grounding, to prevent leakage accidents, lightning protection, LED body and housing should have good grounding measures, and according to the display is independent, or attached to the building's outer wall to consider the grounding form. At the same time, the electronic components in the outdoor led advertising screen have high integration, and the sensitivity requirements for anti-interference are also higher and higher. In order to minimize electromagnetic interference, lightning protection devices should usually be installed on the display screen and buildings.
The violent storms have ravaged the LED advertising screen protection level. Usually, the outdoor LED advertising screens have a large installation area, and most of them are installed in places with dense personnel. Therefore, special attention should be paid to the display protection level, especially the southeast coastal areas where typhoons frequently log in. The design should consider the solid foundation of the steel structure, wind load, waterproof, dustproof, moisture-proof and many other factors, the protection level should be IP65 and above, extend the service life of the display and enhance the reliability.
Do a good job of ventilation and heat dissipation to resist high temperature. When the outdoor led billboard works, it will generate a certain amount of heat. If the temperature of the scene is too high and the heat dissipation is poor, the LED chip and related integrated circuits may not work properly or even be burned, thus making the LED display system impossible. Normal work, so usually the outdoor led advertising screen should be equipped with cooling fans or air conditioners, especially for screens that need to work in high temperature subtropical and tropical regions for a long time.
