[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses a dustproof and heat-dissipating LED automotive headlight.

[0025] This utility model provides, for example Figure 1-3 The illustrated dustproof and heat-dissipating LED automotive headlight includes a headlight base 1. A mounting hole is provided on one side of the headlight base 1, and an LED headlight body 2 is fixedly connected inside the mounting hole. A square frame 3 is fixedly connected to one side of the headlight base 1. Two sealing grooves are provided on the outer surface of the square frame 3, and a first sealing ring 4 and a second sealing ring 5 are respectively fitted inside the two sealing grooves. A transparent protective cover 6 is provided on one side of the headlight base 1, and the inner wall of the transparent protective cover 6 is fitted with the two sealing rings. A heat dissipation mechanism is arranged around the outer surface of the LED headlight body 2.

[0026] The first sealing ring 4 and the second sealing ring 5 can be used to seal the interior of the transparent protective cover 6 during the operation of the car, so as to prevent dust from affecting the lighting effect of the LED headlight body.

[0027] To prevent the LED headlight body 2 from overheating during use, such as Figure 1-3 As shown, the heat dissipation mechanism includes a spiral tube 7, two serpentine tubes 8, and a miniature water pump 9. Two through holes are opened on one side of the headlight base 1. The two serpentine tubes 8 are respectively fixedly connected to the inside of the corresponding through holes. The spiral tube 7 is fixedly connected between the two serpentine tubes 8 and sleeved on the outer surface of the LED headlight body 2. The miniature water pump 9 is fixedly connected to one side of the headlight base 1. The ends of the two serpentine tubes 8 away from the serpentine tubes 8 are respectively fixedly connected to one end of the miniature water pump 9.

[0028] The spiral tube 7 and the two serpentine tubes 8 are both filled with condensate. When the LED headlight body 2 is in use, the micro water pump 9 is started, which allows the condensate to flow. When the condensate is inside the spiral tube 7, it can absorb the heat generated by the LED headlight body 2. Then, when the condensate is inside the two serpentine tubes 8, the heated condensate can exchange heat with the air, thereby cooling the condensate and achieving a circulation effect.

[0029] To prevent dust and moisture from entering, such as Figure 2 As shown, the first sealing ring 4 is made of rubber, and the second sealing ring 5 is made of waterproof rubber strip.

[0030] Rubber rings are used to prevent dust from entering the interior of the transparent protective cover 6, while waterproof strips are used to prevent moisture from entering the interior of the transparent protective cover 6.

[0031] In order to ensure a tight connection between the headlight base 1 and the transparent protective cover 6, such as Figure 1-2 As shown, a sealing adhesive 10 is provided between the headlight base 1 and the transparent protective cover 6.

[0032] The transparent protective cover 6 can be tightly bonded to one side of the headlight base 1 using the sealing adhesive 10, so that the headlight base 1 and the transparent protective cover 6 can be tightly connected.

[0033] To improve the heat dissipation efficiency of the condensate, such as Figure 1-2 As shown, a plurality of heat dissipation fins 11 are fixedly connected to one side of the headlight base 1. Each heat dissipation fin 11 has a square hole on its surface, and each square hole is matched with a corresponding serpentine tube 8.

[0034] Each heat dissipation fin 11 can improve the heat dissipation efficiency of the two serpentine tubes 8.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
