How can outdoor LED display operate safely in harsh environm
When we talk about LED displays, There are many kinds of them. As far as Shenzhen is concerned, there are many LED display manufacturers.Considering this, anyone must choose the best-LED supplier to get the maximum productive outcome with the LED display they buy.
1. High temperature protection.
Outdoor LED display screen usually has a large area, which consumes a lot of power in the application process, and the corresponding heat dissipation is also large. In addition, the external temperature is relatively high. If the heat dissipation problem cannot be solved in time, it may lead to problems such as circuit board heating and short circuit. In production, to ensure that the display circuit board in a good state, as far as possible in the shell design, choose hollow design, is conducive to heat dissipation. When installing, according to the equipment situation, insist that the display screen is well ventilated, when necessary, add heat dissipation equipment on the display screen, just like installing air conditioner or fan inside to help the display screen heat dissipation.
2. Typhoon prevention
Outdoor LED display installation location, installation methods are different, wall-mounted, Mosaic, column, suspension, and so on. Therefore, in typhoon season, in order to prevent outdoor led display screen from falling off, the load-bearing steel structure of the display screen has strict requirements. The engineering unit must design and install in strict accordance with the typhoon resistance grade standards, and have a certain seismic capacity, to ensure that outdoor LED display will not fall and cause casualties and other hazards.
Due to the rainy weather in the south, the LED display itself must have a high level of waterproof protection against rain erosion. Outdoor LED display should reach IP65 protection level in outdoor environment. The module should be sealed by filling with glue. Waterproof case is selected, and waterproof rubber ring is used between the module and the case.
Outdoor led display lightning protection has four main parts.
1. Direct lightning protection: when the outdoor LED display screen is not within the direct lightning protection range of nearby high-rise buildings, lightning rods shall be installed on the top of the display screen or near the steel structure;
2. Induction lightning protection: the outdoor LED display power system shall be lightning protection of level 1-2, signal line installation signal shall be lightning protection, and the power system in the machine room shall be lightning protection of level 3, signal out/in equipment T installation signal lightning protection terminal;
3. All LED display circuits (power supply and signals) should be shielded and buried.
