For the installation of outdoor LED electronic large screen, to withstand high temperature, strong wind, heavy rain, thunder and other bad weather, if you do not take protective measures, may bring irreparable losses to end users. The following is a brief introduction about how to prevent the leakage of outdoor LED electronic large screen in Shenzhen rainstorm.
How to prevent leakage of outdoor LED electronic large screen during rainstorm in Shenzhen
With the technology development of LED electronic large screen industry is more and more mature, the LED outdoor display produced by LED display manufacturers has the protection level of IP65, IP67 and IP68. And the mini photoelectric LED display manufacturers will test the products before they leave the factory. In the process of production and packaging, the PCB board should be protected, such as brushing three anti paint, at the same time, the module should be filled with glue, and the waterproof sink should be installed on the module kit. The box is waterproof, and the connection between the module and the box is sealed with glue, and a waterproof groove is reserved to prevent water vapor from entering the inside of the screen.
When installing the LED electronic large screen, add the back plate and apply sealant to avoid water vapor entering into the electronic components. If the water vapor enters into the electronic components, it may cause short circuit or fire, and then fire the whole screen, causing irreparable impact. And to apply a waterproof coating on the back panel, you need to pay attention to the waterproof performance of the aluminum-plastic panel of the small strip display on the back. You can use an electric drill to design a row of drainage outlets under the aluminum-plastic panel to prevent ponding.
If the LED electronic large screen is closely combined with the backplane, the bottom must be leaky. The so-called leak is used to leak. No matter how tightly the front and back of the LED electronic large screen are combined, over time, there will be more or less water in it. If there is no water leakage hole in the lower opening, the water will accumulate more and more over time, causing losses to the screen. If a leak hole is made, the water will flow towards the leak hole until it has a good waterproof effect.
When installing the LED electronic large screen, the plug wiring must select the appropriate wire, and generally abide by the principle of rather large than small. That is to say, under the total power of LED electronic large screen, choose the wire which is a little higher than the total power, and do not choose the wire which is just right or with low power, so it is easy to lead to line burn and irreparable loss.
In addition, it should be noted that in the specific construction site, the structure design should be combined with the above. After the structure is determined, according to the characteristics of the structure, the sealing strip material with hollow foam tube structure, low compression set rate and high elongation at break is considered. Then, according to the characteristics of the sealing strip material, the appropriate contact surface and contact force are designed to make the sealing strip extruded to a dense state.
If the LED electronic large screen is flooded, the solution is as follows:
Use fan or other tools to dry the LED display completely with the fastest speed.
The above is the mini photoelectric LED display manufacturers briefly introduce how to prevent the leakage of LED electronic large screen in Shenzhen. Before the LED display manufacturers leave the factory, they will brush the PCB with three proofing paint, glue the module, and select the waterproof and sealed box. In the installation, the back plate should be added, the sealant should be applied, the drainage port should be reserved, the appropriate wire and the appropriate structure should be selected for installation, so as to avoid the water vapor entering into the screen body and causing irreparable losses.
