After the production and use of LED billboards, the biggest problem with the LED display is that the LED display will produce heat, and the problem of heat dissipation needs to be solved. The reason for this is that the function of the LED display consumes a lot, which is equivalent to a part of the energy wasted on the heating. When you're hot, it can cause several problems.

The wavelength has a drift phenomenon, which will cause problems in color correction, and the wavelength drift of the LED will be relatively large when the temperature is relatively high or when the temperature is relatively low. According to the experimental data, it can be shown that every time the temperature changes by one degree, its wavelength will change.

The brightness of the output is reduced, and this change, especially on the red light, will be relatively large. Compared with the red light, the effect of the blue light and the green light on the temperature is not so obvious, especially for the blue light will not have much impact.
