Description

Technical Field

[0001] This utility model relates to the field of automotive headlight technology, and in particular to an automotive front lighting headlight. Background Technology

[0002] Headlights are the lighting devices mounted on both sides of a car's front, used for driving in low-light conditions. The effectiveness of headlights directly impacts driving maneuverability and traffic safety in low-light environments. Therefore, traffic management departments worldwide generally regulate headlight lighting standards by law to ensure driving safety. Currently, to achieve greater illumination distances, vehicle headlights are becoming increasingly powerful. Simultaneously, to maintain the same headlight size, the density of LEDs on the headlight assembly is increasing, making heat dissipation a critical issue.

[0003] In the prior art, there is a Chinese utility model patent with publication number CN220728003U entitled "An Automobile Headlight, an Automobile Headlight System and an Automobile". In order to extend the lighting distance, multiple lamp beads are concentrated on the lamp plate, and then heat dissipation holes are opened on the headlight. However, this natural heat dissipation method is not very effective, and the heat dissipation path from the heat-generating area of ​​the lamp bead to the heat dissipation hole is long, resulting in slower heat dissipation. Utility Model Content

[0004] The purpose of this invention is to provide an automotive headlight that solves the problems of poor heat dissipation in existing headlights and the long and slow heat dissipation path from the heat-generating area of ​​the LED to the heat dissipation hole.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A car headlight includes a housing, a heat dissipation bracket, a heat dissipation ring, a solenoid valve, a lamp bead copper plate, and a heat dissipation chamber. The heat dissipation bracket is disposed between the housing and the heat dissipation chamber. The heat dissipation ring is mounted on the head end face of the housing. The solenoid valve and the lamp bead copper plate are both disposed on the heat dissipation bracket.

[0006] A further technical solution is that an air inlet is provided on the heat dissipation bracket.

[0007] A further technical solution is: the heat dissipation chamber includes a heat dissipation shell and a fan, the heat dissipation shell is disposed on the heat dissipation bracket, and the fan is disposed on the air outlet of the heat dissipation shell.

[0008] A further technical solution is that the fan and air outlet are provided at both the tail end and the top of the heat sink.

[0009] A further technical solution is that an air inlet channel is provided at the bottom of the heat dissipation bracket, and the air outlet of the air inlet channel corresponds to the fan.

[0010] A further technical solution is that the tail end of the heat dissipation bracket is provided with heat dissipation fins close to the heat dissipation chamber.

[0011] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: This invention proposes an automotive headlight with more LEDs concentrated on a copper plate, which also generates more heat. The headlight's heat dissipation bracket can more quickly conduct the heat generated at the front of the headlight to the heat dissipation chamber, which then rapidly expels the heat outside the headlight. A heat dissipation ring also assists in heat dissipation. This headlight exhibits stable and reliable heat dissipation efficiency, ensuring its normal operating performance.

[0023] This implementation example Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an automotive headlight includes a housing 1, a heat dissipation bracket 2, a heat dissipation surface ring 3, a solenoid valve 4, a lamp bead copper plate 5, and a heat dissipation chamber 6. The heat dissipation bracket 2 is disposed between the housing 1 and the heat dissipation chamber 6. The heat dissipation surface ring 3 is mounted on the head end face of the housing 1. The solenoid valve 4 and the lamp bead copper plate 5 are both disposed on the heat dissipation bracket 2.

[0024] The housing 1, heat sink bracket 2, and heat sink chamber 6 are connected by screws. The LED copper plate 5 is then mounted on the heat sink bracket 2 at the head of the housing 1. The lens is then mounted on the outer end of the housing 1. The solenoid valve 4, when energized, handles the switching between low and high beams. The heat sink bracket 2 and heat sink ring 3 serve a dual function of fixing and dissipating heat: on one hand, they provide reliable mounting and fixing for the solenoid valve 4 and LED copper plate 5, preventing component displacement; on the other hand, they accelerate heat conduction and dissipation, creating a good thermal environment for the solenoid valve 4 and LED copper plate 5, ensuring stable performance. The heat sink bracket 2 can more quickly conduct the heat generated at the front of the headlight to the heat sink chamber 6, and then the heat sink chamber 6 quickly dissipates the heat outside the headlight. Simultaneously, the heat sink ring 3 also assists in heat dissipation. The headlight's heat dissipation efficiency is stable and reliable, ensuring the normal operating efficiency of the headlight.

[0025] Preferably, the heat dissipation bracket 2 is provided with an air inlet 7.

[0026] Air intake 7 can draw cool air from the outside environment into the headlight for heat dissipation.

[0027] Preferably, the heat dissipation chamber 6 includes a heat dissipation shell 8 and a fan 9. The heat dissipation shell 8 is mounted on the heat dissipation bracket 2, and the fan 9 is mounted on the air outlet of the heat dissipation shell 8.

[0028] The heat dissipation bracket 2 can direct the heat generated by the headlight bulb to the heat dissipation chamber 6, and the fan 9 starts to exhaust air outward to remove the heat from the heat dissipation chamber 6, thus promoting heat dissipation.

[0029] Fan 9 can also dissipate heat from heat sink 2.

[0030] Preferably, a fan 9 and an air outlet are provided at both the tail end and the top of the heat sink 8.

[0031] When the fan 9 at the top exhaust port of the heat sink 8 is drawing air, it can create a deflection effect, working together with the fan 9 at the rear of the heat sink 8 to improve heat dissipation efficiency.

[0032] Preferably, the bottom of the heat dissipation bracket 2 is provided with an air inlet channel, and the air outlet of the air inlet channel corresponds to the fan 9.

[0033] Airflow flows out through the air intake channel at the bottom of the heat sink bracket 2, and the fan 9 at the top air outlet of the heat sink 8 can form a deflection when drawing air.

[0034] Preferably, the tail of the heat dissipation bracket 2 is provided with heat dissipation fins 10 near the heat dissipation chamber 6.

[0035] The heat dissipation fins 10 can improve the heat dissipation effect of the heat dissipation bracket 10.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
