In practical applications, increasing the heat dissipation of the LED display not only effectively improves the efficiency of the heat dissipation of the LED display, but also saves power, and is more conducive to improving the life of the LED display.

1. Fan heat dissipation, use long-life and high-efficiency fans inside the lamp housing to enhance heat dissipation. This is a common method with low cost and good effect.
2. Use aluminum fins, which is the most common way to dissipate heat. Use aluminum fins as a part of the shell to increase the heat dissipation area.
3. Air fluid mechanics uses the shape of the lamp housing to create convective air, which is the lowest cost method of enhancing heat dissipation.
4. Surface radiation heat dissipation treatment. The surface of the lamp housing is treated with radiation heat dissipation. The simpler is to apply radiation heat dissipation paint, which can take the heat away from the surface of the lamp housing by radiation.

5. Integration of heat conduction and heat dissipation-the use of high thermal conductivity ceramics, the purpose of heat dissipation of the lamp shell is to reduce the working temperature of the LED high-definition display chip. Because the expansion coefficient of the LED chip and our usual metal heat conduction and heat dissipation materials have a large gap, It is not possible to solder the LED chip directly to avoid damage to the LED display chip due to high and low temperature thermal stress.
6. Heat pipe heat dissipation, use heat pipe technology to guide the heat from the LED display chip to the heat dissipation fins of the shell.
7. The thermally conductive plastic shell is filled with thermally conductive material when the plastic shell is injection molded, so as to increase the thermal conductivity and heat dissipation capacity of the plastic shell.
It can be seen that the maturity and progress of LED display heat dissipation technology will be beneficial to its saving and environmental protection concept. LED electronic display manufacturers have a variety of methods to improve the heat dissipation of LED display in the production of LED display. Depending on the power and the place of use, there will be different considerations for heat dissipation.
