How to solve the heat dissipation problem of LED display screen?
Compared with the LED display screen for timing and scoring, the large LED screen installed in the stadium is more visible to the audience. The whole course of the competition and the wonderful moments of the athletes can be displayed in high definition; Slow motion replay assists the referee to judge the score and maintain the fairness and justice of the game; The broadcast of commercial advertisements adds to the beauty of the competition site. The perfect picture quality and sound effect make the scene more competitive and shocking. The timeliness and viewing of the information presented by LED display screen is difficult to be compared with other display carriers in stadiums.
Qatar is an Arab country in southwest Asia, located on the Qatar peninsula on the southwest coast of the Persian Gulf. Qatar has hosted the 2006 Doha Asian Games and the 2011 Asian Cup football match, and won the right to host the 22nd World Cup football match in 2022.
As we all know, there are numerous types of LED screens, including: LED indoor and outdoor full-color advertising screens, led transparent screens, led stage rental screens, led stadium screens, etc. since LED screens are electronic equipment and have basic power supplies and components, the heat generated is naturally not small. So what control range is appropriate for the heat generated?What are the characteristics of outdoor LED screen?
In some daily LED strip screens, it is generally unnecessary to install additional heat dissipation equipment, because the LED strip screen is not high but long. In addition, most of the LED modules installed in daily life are semi outdoor modules. There is a space to dissipate the heat, so there is no need to install additional cooling equipment.
Another kind is the indoor monochrome LED screen. Like the above LED strip screen, this kind of screen does not need to be specially cooled. Because the module of this screen is magnetic attraction type, there is space between the two modules, and the heat will be directly dissipated. It is also unnecessary to install additional heat sink equipment. Teach you how to repair the LED display.
However, for outdoor LED large screen, it is necessary to install additional heat dissipation equipment. There are several matters needing attention for this screen:
1. Waterproof is the key. Usually, some of the large screens are installed on the column, some are hung on the outer wall of the building, and some are inlaid. Like the above placement methods, the sealing must be tightly controlled. Otherwise, if there is water or water vapor, the circuit of the LED screen will be in poor contact, causing short circuit and causing danger.
2. The outdoor LED large screen has high brightness, because the brightness must be greater than the light intensity to display a clear picture, so that is why the outdoor power is higher than the indoor power, and then the heat generated by the high power is also high. However, some people say it is unnecessary to install it. Here, I will talk about the possible consequences. If it is not installed, the biggest impact will be the temperature of the body inside the screen. High temperature inside the screen will lead to premature aging and damage of components, and the LED screen may have the risk of IC breakdown in the short term.
There are two main types of heat dissipation equipment:
1. If the LED screen area is less than 20 square meters, the convection fan can be used. The external louvers can prevent rain from entering the screen.
2. If the LED screen area is more than 20 square meters, a small air conditioner should be installed to cool down. Almost every 20 square meters of LED screen needs a 2p air conditioner.
