Description

Technical Field

[0001] This utility model relates to the field of LED light source technology, specifically a high-performance LED light source for special purposes. Background Technology

[0002] In specialized lighting applications (such as UV curing and plant lighting), LED light sources need to operate at high temperatures and high current densities for extended periods, emitting light of specific wavelengths. Existing technologies for such LED light sources typically suffer from the following technical drawbacks: traditional metal substrates (such as aluminum substrates) or ceramic substrates have limited thermal conductivity, and their thermal expansion coefficients do not match those of the LED chip. Prolonged high-temperature operation can easily lead to cracking of the chip's solder layer and breakage of gold wires, significantly shortening the lifespan of the light source. To address these issues, we propose a high-performance LED light source for specialized applications. Utility Model Content

[0003] The purpose of this invention is to provide a high-performance LED light source for special purposes to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-performance special-purpose LED light source, comprising: A lamp holder has a circuit board fixedly mounted on its bottom wall, and multiple evenly distributed LED chips fixedly mounted on the bottom wall of the circuit board. A lamp cover is fixedly mounted on the bottom wall of the lamp holder, covering the circuit board and the multiple LED chips. The lamp holder is equipped with a heat dissipation mechanism, which includes a heat dissipation shroud and a heat-conducting plate. The heat dissipation shroud is fixedly mounted on the top wall of the lamp holder, and a serpentine heat-conducting pipe is fixedly mounted inside the heat dissipation shroud. The bottom wall of the lamp holder has a mounting groove adapted to the heat-conducting plate, and the heat-conducting plate is fixedly mounted in the mounting groove. The bottom wall of the heat-conducting plate is in contact with the top wall of the circuit board. Multiple sets of U-shaped heat-conducting sheets are fixedly welded to the top wall of the heat-conducting plate, and the multiple sets of U-shaped heat-conducting sheets are fixedly bonded to the outer wall of the serpentine heat-conducting pipe.

[0005] Preferably, both ends of the serpentine heat pipe are fixedly welded with connecting pipes, and threaded quick connectors are fixedly welded to both connecting pipes.

[0006] Preferably, a connecting column is fixedly welded to the top wall of the heat sink, and a mounting base is fixedly welded to the top of the connecting column. The mounting base has multiple annularly distributed mounting holes.

[0007] Preferably, both the heat-conducting plate and the U-shaped heat-conducting sheet are made of aluminum.

[0008] Preferably, the serpentine heat pipe is made of copper.

[0009] Compared with the prior art, the beneficial effects of this utility model are: In use, the threaded quick-connect fittings at both ends of the serpentine heat pipe are connected to an external cold liquid circulation and delivery device, allowing the cryogenic liquid to circulate within the serpentine heat pipe. The heat-conducting plates absorb the heat generated by the circuit board and LED chip, and transfer the heat to multiple U-shaped heat-conducting plates. As the cryogenic liquid flows through the serpentine heat pipe, it carries away the heat from the U-shaped heat-conducting plates, facilitating rapid heat dissipation of the LED light source during use. This ensures the stability and lifespan of the LED light source, giving it better heat dissipation performance when used in special environments. Attached Figure Description
