Outdoor LED display is the earliest application environment is the most widely application scope, area from dozens to hundreds or even thousands of square meters.Large area, let its display effect have unparalleled shock and advantage.But at the same time, why get better show general LED display is installed on high.Such words will face bad weather such as wind, thunderstorms, sand and dust test.So we must provide for LED display a variety of preventive measures, in order to ensure its normal operation.

1. LED display protection grade

Are typically installed outdoor LED display area is larger, and mostly installed in personnel intensive place, so it is important to pay special attention to the screen protection grade, especially typhoon often log in the southeast coastal areas.It want to consider the solid foundation of steel structure design, wind load, waterproof, dustproof, moisture, and many other factors, protection grade to IP65 and above, prolong the service life of display, enhancing reliability.

2. The lightning protection grounding, prevent leakage accidents

Lighting protection done, LED the main body and the shell to have good grounding measures, and according to the display screen is independent setting, or attached in building external wall considering its grounding form respectively.
At the same time, in the outdoor LED display electronic integration is high, the sensitivity against interference requirements also more and more high, in order to try to weaken the electromagnetic interference usually should be installed on the screen and building lightning protection devices.

3. Good ventilation cooling to resist high temperature

  Outdoor LED display work will produce a certain quantity of heat, if the environment temperature and heat dissipation, the LED chip and integrated circuit may not work properly, and even destroyed, so that the LED display system cannot work normally, so usually outdoor LED display screen to add a cooling fan or air conditioning label, especially for the need for a long time work in the high temperature of subtropical and tropical areas for screen.
