Outdoor LED display anti-freezing rain solution

"Solutions against Freezing Rain for Outdoor LED Displays" In the cold winter, outdoor LED displays will encounter freezing rain caused by severe cold. As the freezing rain drips into ice, it will shrink the epoxy resin part of the LED display mask and lamp beads. The most direct impact is cracking and deformation. The circuit boards, connectors, and wires inside the LED display box will also be affected by low temperature and form water drops on the surface. If not handled in time, it will corrode the related materials and cause old damage. . How to effectively prevent condensation and waterproof, improve the life of LED display circuit boards, and save repair costs has become a major problem in the quality of outdoor LED displays. Therefore, in view of the problems that outdoor LED displays are prone to condensation and short life in harsh environments, we Let’s take a look at the related solutions: Method 1: To solve the problem of condensation on the outdoor LED display, you can use heating, electric heating, and add an anti-condensation device inside the LED display to make the inside of the LED display The temperature is always kept higher than the ambient temperature outside the LED screen, and the relative humidity inside the LED screen is reduced as much as possible, which can completely prevent condensation in the LED screen. Method 2: To deal with the anti-condensation problem of outdoor LED displays, the effect of three-proof paint can be used. According to the analysis of this situation, the anti-condensation three-proof paint solution is used. On the one hand, it solves the problem of condensation on the circuit board, and on the other hand Aspects can improve product life.

In view of the condensation problem of outdoor LED displays, many outdoor LED display applications in my country do not protect circuit board products, so the problem is widespread. The principle of the anti-condensation solution for anti-condensation conformal paint removal is mainly to attach a layer of micron-level anti-condensation conformal paint to the surface of the circuit board through low-concentration micron coating technology. It has extremely low surface tension, so that If not, the condensation on the circuit board will automatically slide off, thus achieving the anti-condensation effect. Outdoor LED display screens are extremely prone to condensation and water droplets on the circuit board under such uncertain conditions as wind, rain, lightning and snow, high and low temperature changes, which will affect the LED display screen. In this case, the product life is only indoor LED display. About 40% of the screen.

As we all know, condensation is a potential hidden danger of outdoor LED display screens, especially for components such as LED module connectors that do not have three waterproof coatings. Condensation is very likely to corrode the metal materials of the components, thus affecting The performance of plugging will affect the display effect of outdoor LED display. .
