Problems solved by technology

However, the heat dissipation method of the LED light source in the prior art generally adopts the natural air-cooled radiator for heat dissipation. Although the natural air-cooled radiator has the advantages of simple structure and no energy consumption during heat dissipation, due to Its heat dissipation effect is poor, which often makes the LED light-emitting diode as a light source work at its own high temperature, especially the high-power integrated small-area LED light board will work at a temperature higher than 130 ° C, so that the LED light-emitting diode The luminous efficiency of the LED tube is aging ahead of time, which not only increases the energy consumption of the LED light-emitting diode, but also greatly shortens its service life and increases the cost of use.

In addition, the use of existing air-cooled radiators for heat dissipation still has problems such as large volume and heavy weight.

Due to the above-mentioned problems in the heat dissipation method of the existing LED light source, when making LED light source products, the power of the LED light source is usually controlled below 100 watts, which undoubtedly limits the use and promotion of the LED light source

Therefore, the heat dissipation method of the existing LED light source using LED light-emitting diodes as the light source is still not ideal, and the effect of the existing LED light source cannot be fully utilized.
