Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, and more specifically to an LED light based on a superconducting heat pipe. Background Technology

[0002] Existing vehicles widely use LED lights as headlights, but in order to achieve high brightness, LED lights often have high power, resulting in a lot of heat generation. Most current LEDs are made of aluminum profiles and NC machining, which has poor heat dissipation. To improve heat dissipation, many heat dissipation structures are usually added, which makes the LED lights larger, the production process more complicated, and the production cost higher.

[0008] Two LED beads are provided, which are respectively attached to the two sides of the front part of the heat conductor.

[0009] The heat pipe has a capillary layer inside, which is a porous structure formed by sintering copper powder.

A VC (Vacuum Chamber) is a highly efficient heat conduction component with a capillary structure on its inner wall.

[0023] Furthermore, the PCB board containing the conductor is printed onto the surface of the insulating coating.

[0024] Furthermore, the outer surface of the PCB board 9 is coated with an insulating varnish layer.

[0025] Furthermore, two LED beads are provided, which are respectively attached to the two sides of the front part of the heat conductor.

[0026] Furthermore, the heat pipe has a capillary structure layer inside, which is a porous structure formed by sintering copper powder.

[0027] Furthermore, one end of the heat conductor 1 is embedded inside the heat sink 4, and a cooling fan 5 is installed at the end of the heat sink. The fan has a fan housing 7 on its outside, and the fan housing 7 has holes for the wires 8 to pass through.
