Description

Technical Field

[0001] This utility model relates to the field of automotive lighting technology, and in particular to an LED automotive light with good heat dissipation performance. Background Technology

[0002] Vehicle lights refer to the lights on a vehicle. Chinese patent CN117605975A discloses a headlight module and vehicle light assembly, which uses a radiator, cooling fan, and water-cooling circulation component to cool the LED light circuit board. However, the water-cooling pipes on the water-cooling circulation component are only arranged around the side of the LED light circuit board. The heat from the side of the LED light circuit board is transferred to the water-cooling pipes and the internal liquid, resulting in limited cooling effect. Therefore, how to design an LED automotive light with better cooling effect has become an urgent technical problem to be solved. Utility Model Content

[0003] In order to overcome the existing technical defects, the purpose of this utility model is to provide an LED automotive lamp with better heat dissipation performance to solve the above-mentioned technical problems.

[0004] The technical solution adopted by this utility model to solve the technical problem is as follows:

[0005] According to one aspect of this utility model, an LED automotive light with good heat dissipation performance is designed, comprising:

[0006] LED light panel, with LED beads set on the top and bottom, and a mounting bracket connected to the right end;

[0007] A radiator is connected to the right side of the mounting base. The radiator includes a heat sink and several heat sink fins disposed on the right side of the heat sink. The liquid storage chamber inside the heat sink stores coolant.

[0008] The outer casing is connected to the right side of the heat sink. The outer casing is hollow, with an air inlet on the right side and an air outlet on the left side. The heat sink is located inside the outer casing, and a cooling fan for blowing air onto the heat sink is provided on the right side inside the outer casing.

[0009] A control circuit board is located between the mounting base and the heat sink, and the cooling fan and the LED beads on the LED light board are electrically connected to the control circuit board respectively.

[0010] A circulating pump, the inlet end of which is connected to and communicates with the outlet on the heat sink;

[0011] The LED light panel has a first metal tube in contact with its side, a second metal tube in contact with its top surface, and a third metal tube in contact with its bottom surface. The outlet of the circulation pump is connected to and communicates with the inlet of the first metal tube, the inlet of the second metal tube, and the inlet of the third metal tube. The outlets of the three tubes are connected to and communicate with the return port on the heat sink. The circulation pump is used to drive the coolant in the storage chamber into the first metal tube, the second metal tube, and the third metal tube and back to the storage chamber.

[0012] By adopting the above technical solution, metal tubes are respectively installed on the side, top, and bottom of the LED light panel. The heat generated by the LED light panel illumination can be transferred from its side, top, and bottom to the three metal tubes and the coolant inside the metal tubes, which quickly realizes the heat transfer of the LED light panel and improves the heat dissipation effect of the LED automotive light. By setting a liquid storage chamber in the heat sink, the contact surface between the coolant and the heat sink can be increased, which facilitates the rapid transfer of heat from the coolant to the heat sink and heat sink fins. When the cooling fan is activated, it blows air onto the heat sink fins to carry away the heat, thereby further improving the heat dissipation effect.

[0013] To better address the aforementioned technical deficiencies, this utility model also offers a superior technical solution:

[0014] In some embodiments, a groove is provided on the left side of the heat sink, and the control circuit board is located in the groove. The right end of the LED light panel contacts and is fixed to the control circuit board. The left side of the control circuit board contacts the mounting bracket, and the right side contacts the heat sink. The LED light panel illumination allows the generated heat to be directly transferred to the control circuit board, and the heat on the control circuit board is then transferred to the heat sink and heat sink fins, further improving the heat dissipation effect.

[0015] In some embodiments, insulating and thermally conductive silicone is provided between the left side of the control circuit board and the mounting bracket, and between the right side and the heat sink. This improves heat transfer and facilitates heat dissipation.

[0016] In some embodiments, the first, second, and third metal tubes are all square tubes, and the overall structure is U-shaped. Using a square tube structure increases the contact area between the metal tubes and the LED panel, facilitating heat transfer and improving heat dissipation performance.

[0017] In some embodiments, the mounting base is made of metal, with at least two snap-fit ​​blocks distributed around its left circumference, and a silicone sealing ring fitted onto the left end of the mounting base. The silicone sealing ring enables a sealed installation. Attached Figure Description
