[0002] LED vehicle lamps refer to lamps that use LED technology for both external and internal light sources for external and internal lighting. As end consumers have higher and higher requirements for the appearance of vehicle lamps, and as the number of LEDs used in vehicle lamps increases, the probability of problems with LEDs also increases. Therefore, the requirements for the performance reliability of LED products are getting higher and higher. At the same time, vehicle manufacturers have increasingly stringent requirements for LED suppliers.
[0003] When traveling at night, lights need to be used for a long time for lighting. After the LED vehicle lamps are used for a long time, a large amount of heat will be generated. The existing lamp bases are relatively enclosed and do not have corresponding heat dissipation structures to dissipate heat, so the vehicle lamps are prone to failure. Summary of the Utility Model

An installation frame is arranged inside the lamp base, and the installation frame is used for installing the LED lamp. Installation glue is arranged on the installation frame. A high heat dissipation mechanism is arranged inside the lamp base, and the high heat dissipation mechanism is used for efficiently dissipating heat from the LED lamp. A first air box is arranged outside the lamp base, a first fan is arranged inside the first air box, and four second air boxes are arranged on the side of the first air box.
[0007] As a further scheme of the utility model, a light-transmitting plate is arranged on the lamp base, and the light-transmitting plate is detachable and installable on the lamp base.
[0008] As a further scheme of the utility model, a first filter screen is arranged inside the first air box, and a second filter screen is arranged outside the first air box.
[0009] As a further scheme of the utility model, the high heat dissipation mechanism includes a semiconductor refrigeration sheet. A heat conduction block is arranged on one side of the semiconductor refrigeration sheet. The side where the semiconductor refrigeration sheet is connected to the heat conduction block is for refrigeration. The heat conduction block is attached to the end of the LED lamp. A metal heat dissipation plate is arranged on the other side of the semiconductor refrigeration sheet, and heat dissipation fins are arranged on the metal heat dissipation plate, and the heat dissipation fins face the first air box.
[0010] As a further solution of the present utility model, a connecting piece is arranged outside the high heat dissipation mechanism, and the connecting piece wraps the high heat dissipation mechanism and one end of the first air box.
[0011] As a further solution of the present utility model, a second fan is arranged inside the second air box, and a third filter screen is arranged outside the second fan.
[0012] The beneficial effects of the present utility model are as follows:
[0013] 1. The LED lamp is fixed by the mounting glue, the second fan dissipates heat from the inside of the lamp holder and the LED lamp, reducing the internal temperature, and the third filter screen can block external impurities.
[0014] 2. When the temperature of the LED car lamp is too high, the side of the semiconductor refrigeration sheet connected to the heat conduction block refrigerates, the heat conduction block is attached to the end of the LED lamp, the semiconductor refrigeration sheet refrigerates the heat conduction block, and the temperature of the LED lamp is quickly reduced through the heat conduction block.
[0015] 3. After refrigeration, the other side of the semiconductor refrigeration sheet is in a high heat state.

Detailed implementation mode
[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0023] Refer to Figures 1-4 , an automotive LED headlight base of a high heat dissipation module, including a lamp holder 1 and an LED lamp 11. The lamp holder 1 is the base of the automotive LED headlight, which is installed on the vehicle, used for installing the automotive LED headlight, and dissipating heat through an internal device to avoid malfunction. The LED lamp 11 is the automotive LED headlight. An installation frame 13 is arranged inside the lamp holder 1. The installation frame 13 is used for installing the LED lamp 11. Mounting glue 14 is arranged on the installation frame 13, and the LED lamp 11 is fixed through the mounting glue 14. A light-transmitting plate 12 is arranged on the lamp holder 1. The light-transmitting plate 12 is the outer structure of the LED lamp 11, protecting the LED lamp 11, and the light-transmitting plate 12 is disassembled and assembled on the lamp holder 1.
[0024] A first air box 3 is arranged outside the lamp holder 1. A first fan 31 is arranged inside the first air box 3. A first filter screen 32 is arranged on the inner side of the first air box 3, and a second filter screen 33 is arranged on the outer side of the first air box 3. When the first fan 31 is started, dust and impurities are blocked by the first filter screen 32 and the second filter screen 33 on both the inside and outside to prevent dust and impurities from entering the first air box 3 or the lamp holder 1. Four second air boxes 4 are arranged on the side of the first air box 3. A second fan 41 is arranged inside the second air box 4. A third filter screen 42 is arranged outside the second fan 41. The second fan 41 dissipates heat from the inside of the lamp holder 1 and the LED lamp 11 to reduce the internal temperature, and the third filter screen 42 can block external impurities.
[0025] Inside the lamp holder 1, a high heat dissipation mechanism is provided. The high heat dissipation mechanism is used to efficiently dissipate heat from the LED lamp 11. The high heat dissipation mechanism includes a thermoelectric cooler 2. On one side of the thermoelectric cooler 2, there is a heat conduction block 21. The side of the thermoelectric cooler 2 connected to the heat conduction block 21 cools. The heat conduction block 21 is attached to the end of the LED lamp 11. When the LED lamp 11 inside the lamp holder 1 overheats, the thermoelectric cooler 2 cools the heat conduction block 21, and the temperature of the LED lamp 11 is quickly reduced through the heat conduction block 21. After cooling, the other side of the thermoelectric cooler 2 is in a high heat state. On the other side of the thermoelectric cooler 2, there is a metal heat dissipation plate 22. On the metal heat dissipation plate 22, there are heat dissipation fins 23. The heat on the other side of the thermoelectric cooler 2 is quickly absorbed by the metal heat dissipation plate 22, and then the heat is transferred to the multi-row heat dissipation fins 23. The heat dissipation fins 23 face the first air box 3. The heat dissipation fins 23 are cooled by the first fan 31 in the first air box 3, so that the LED lamp 11 can be quickly cooled. Outside the high heat dissipation mechanism, there is a connecting piece 24. The connecting piece 24 wraps the high heat dissipation mechanism and one end of the first air box 3, that is, the high heat dissipation mechanism and the first air box 3 are connected through the connecting piece 24, so that the heat dissipation is more stable.
[0026] Working principle: The base of the automotive LED headlight installs the LED headlight through the mounting frame 13 and then fixes the LED headlight through the mounting glue 14. When the LED headlight is in use, the second fan 41 cools the inside of the lamp holder 1 and the LED lamp 11 to reduce the internal temperature. The third filter screen 42 can block external impurities. When the temperature of the LED headlight is too high, the high heat dissipation mechanism is started. The thermoelectric cooler 2 cools the heat conduction block 21, and the temperature of the LED lamp 11 is quickly reduced through the heat conduction block 21. After cooling, the other side of the thermoelectric cooler 2 is in a high heat state. The heat on the other side of the thermoelectric cooler 2 is quickly absorbed by the metal heat dissipation plate 22, and then the heat is transferred to the multi-row heat dissipation fins 23. The heat dissipation fins 23 are cooled by the first fan 31. The first filter screen 32 and the second filter screen 33 on both sides block dust and impurities, preventing dust and impurities from entering the first air box 3 or the lamp holder 1, so that the LED lamp 11 can be quickly cooled.
