Improve the heat dissipation of the LED display only eight points

1. Air hydrodynamics, using the shape of the lamp housing to create convective air, which is the lowest cost method to enhance heat dissipation.

2. 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.

3, 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.

4, the surface radiation heat treatment, the surface of the lamp shell is radiated and heat-dissipated, the simpler is to apply the radiation heat-dissipating paint, which can be carried away from the surface of the lamp shell by radiation.

5, 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. This method is also used on large luminaires such as LED street lights .

6. 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.

7. Using a liquid bulb encapsulation technique, a transparent liquid having a high thermal conductivity is filled into the bulb of the lamp body.

8, 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 operating temperature of the LED display chip, because the LED chip expansion coefficient and our common metal heat conduction, heat dissipation material expansion coefficient is very large, can not The LED chip is directly soldered to prevent high and low temperature thermal stress from damaging the chip of the LED display.

Effectively improve the heat dissipation of the LED display can save power and improve the service life of the LED display.
