Do you know the bad weather prevention measures of outdoor LED display?outdoor led display screen wholesaler

　　The LED display used for outdoor advertising is much higher than ordinary displays. The outdoor LED display will be affected by high temperature, typhoon, heavy rain, and thunderstorm during use. Therefore, safety measures must be taken to maintain the safety of the display screen in severe weather. The following is the preventive measures for the bad weather of outdoor LED display screens.

　　First of all, high temperature prevention, outdoor LED display general area is generally large, the power consumption is large during the application process, and the corresponding heat value is also large. In addition, the external temperature is high, and the heat dissipation problem cannot be solved in time. Essence It is confirmed that the circuit board is in good condition during production. Choose a punch design when designing the shell design can help cool the calories. During installation, according to the display situation, the display situation is well ventilated. When needed, add cooling equipment to the display, just like installing an air conditioner or a blower internally, so that the display is cooling down.

　　Secondly, the installation position of typhoons and outdoor LED displays is different, and the installation methods are different. Then the typhoon season has strict requirements on the load -bearing steel frame structure of the display screen to prevent the screen of the outdoor LED display. While the engineering unit is designed and installed strictly in accordance with the typhoon level standards, it should also have a certain seismic resistance to prevent losses such as outdoor LED display and cause casualties.

　　Third, prevent heavy rain from heavy rain, so the LED display itself can only be eroded by rainwater only when the waterproof protection level is high. In the outdoor use environment, the outdoor LED display must reach the IP65 protection level, the module must be packaged and packaged, the waterproof shell is selected, and the module and the box are connected with the waterproof rubber ring. The lightning protection of the outdoor LED display is mainly composed of four parts.

　　1. Direct lightning protection: The outdoor LED display is not within the direct lightning protection range of nearby high -rise buildings, so a lightning rod needle is needed to set the top or nearby of the display steel structure.

　　2. Sensing lightning protection: Outdoor LED display power supply system performs 1-2 power supply lightning protection, signal line setting signal lightning protection, at the same time, the power supply system is set to level 3 lightning protection, signal output/indoor device side setting signal lightning protection Instrument.

　　3. All LED display lines (power and signals) must be shielded and paved.

　　4. The front and floor -to -room grounding system of the outdoor LED display should meet the system requirements. Generally, the positive ground resistance should be less than or equal to 4oHM, and the floor resistance of the machine room should be less than or equal to 1oHM. Take these protection measures, even in the worst environment, outdoor LED display can work safely. Recently, it has been raining, understanding and mastering the above -mentioned LED display protection measures, even if it is harsh weather, it can make the outdoor LED display safe!
