The LED display will generate heat during use, especially the outdoor LED display, because the environment in which it is used requires a very high brightness, which should be above 4000CD, so the heat generated is very large. In practical applications, improve the LED display The heat dissipation capacity of the led display not only effectively improves the efficiency of the heat dissipation of the led display, but also achieves the effect of saving power. It is more conducive to improving the service life of the led display and ensuring the display effect of the led display. So what are the good ways to To improve the heat dissipation effect of the led display screen, Topsun Optoelectronics will give a brief introduction here. How to do outdoor led display heat dissipation?

1. Fan heat dissipation, use a long-life and high-efficiency fan 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 part of the housing to increase the heat dissipation area.

  3. Integration of heat conduction and heat dissipation-the use of high thermal conductivity ceramics, the purpose of the lamp shell for heat dissipation is to reduce the working temperature of the LED display chip. Because the expansion coefficient of the LED chip is very different from the expansion coefficient of our usual metal heat conduction and heat dissipation materials, it cannot The LED chip is directly soldered to avoid high and low temperature thermal stress from damaging the LED display chip.

  4. Heat pipe heat dissipation, using heat pipe technology to conduct heat from the LED display chip to the heat dissipation fins of the shell.

  5. Air fluid mechanics uses the shape of the lamp housing to create convective air, which is a cost-effective method of enhancing heat dissipation.

  6. 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.

  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. Topsun Optoelectronics has a variety of methods to improve the heat dissipation of LED displays in the production of LED displays. Depending on the power level and the place of use, different considerations will be applied to the heat dissipation.
