Description

Technical Field

[0002] High-power LED light source (COB) refers to the chip directly bound and packaged on the entire substrate, that is, N chips are integrated together on the inner substrate for packaging. It is mainly used to solve the problem of low-power chips manufacturing high-power LED lamps. It can disperse the heat dissipation of the chip, improve the light efficiency, and improve the glare effect of LED lamps. High-power LED light source (COB) is a popular light source in the market. Since COB light source is integrated, it generates much more heat than low-power LED. The light efficiency of LED is closely related to the junction temperature. If there is no good heat dissipation or cooling device, the light efficiency of LED will be seriously affected.

[0003] In the prior art, there is a portable high-power LED light source lamp bead cooling device with patent announcement number CN205782751U. The dual-fan cooling of the above patent ensures a better cooling effect on the cooling side. The large cooling aluminum block stores more cold air, which ensures that the lamp bead temperature rises too quickly. However, in actual use, there are still the following shortcomings: only dual-fan cooling can be used for cooling. When the dual fans suddenly lose power, the temperature inside the high-power LED light source lamp bead cannot be maintained.

[0004] Therefore, a portable high-power LED light source lamp bead heat dissipation device is needed to solve the problem that the existing technology only has dual fans for heat dissipation and cannot maintain the temperature inside the high-power LED light source lamp bead when the dual fans suddenly lose power.
