Cooling LED video wall is the work of using high-power LED display primary solution of big problems. The main measures to solve the heat problem of LED video wall is to use the new packaging structure and packaging materials, adhesive materials, such as light shell surface for heat radiation processing. Especially in summer, when outdoor led display work itself to produce large amount of heat, heat is not good, the chip temperature is too Gao, it will accelerate the aging of the device and the phosphor, and is likely to cause a short-circuit and so on led display. But also make LED generated light fades, color drift, shorten lifetime, even when serious burn chips. If the temperature rises, the blue LED wavelength becomes longer, so that the white LED color temperature. As blue wavelength deviate too much, it will reduce the phosphor conversion efficiency and light extraction efficiency, while also changing the LED radiation, the wavelength of light, eventually leading LED video wall color temperature, color changes, affecting the quality of luminescence. In short, if the cooling effect of LED video wall is good, you can mention Gao efficiency outdoor led display light. Increased power output, improves optical performance and reliability for outdoor led display. At this stage, when you install the LED video wall is mainly taken by fans or air conditioning to heat, which is the LED display common fault and handling method. LED video wall must have good heat dissipation design, can extend the life of the LED display, to a large extent reduce the loss of the display, so manufacturers must pay attention to Shenzhen LED display cooling.
