1. The fan dissipates heat, and the inside of the lamp housing uses a long-life and high-efficiency fan to enhance heat dissipation. The commonly used method has low cost and good effect.


2, the use of aluminum fins, this is the most common way to dissipate heat, using aluminum fins as part of the shell to increase the heat dissipation area.

3, air fluid mechanics, using the shape of the lamp housing to create convective air, which is the lowest cost to enhance the heat dissipation method.

4, surface radiation heat treatment, the surface of the lamp shell to do radiation heat treatment, the simpler is to apply radiation heat sink paint, you can take the heat away from the surface of the lamp shell.

5, heat conduction and heat dissipation integration - the use of high thermal conductivity ceramics, the purpose of heat dissipation of the lamp housing is to reduce the working temperature of the LED high-definition display chip, because the LED chip expansion coefficient and our common metal heat conduction, heat dissipation material expansion coefficient is very different, The LED chip cannot be directly soldered to prevent high and low temperature thermal stress from damaging the chip of the LED display.www.ledbillboardadvertising.com/Products/

6, the heat pipe heat dissipation, using the heat pipe technology, the heat is led from the LED display chip to the shell heat sink fins.

7. The heat-conducting plastic shell is filled with the heat-conducting material during the injection molding of the plastic shell, thereby increasing the heat-conducting and heat-dissipating ability of the plastic shell.
