Description

Technical Field

[0001] The utility model relates to an automobile lamp, in particular to an automobile headlamp with a heat dissipation structure. Background Art

[0002] Car lights are a type of traffic light device installed on a car for driving lighting and signaling. Car lights are generally divided into two categories: lighting lights and signal lights. Lighting lights are used for driving lighting and to enhance the driver's visual range, while signal lights are used for driving signal warnings.

[0003] Traditional halogen automotive headlights and LED headlights mostly use die-cast aluminum or drawn aluminum plus fans for heat dissipation. Due to the simple technical solutions, the heat dissipation method of die-cast aluminum or drawn aluminum plus fans alone cannot meet the current heat dissipation requirements of automotive headlights.

[0004] In existing technologies, when a vehicle headlamp is equipped with multiple or various light sources, the light sources are disposed on both sides of a heat dissipation substrate. However, the light sources on both sides of the heat dissipation substrate are positioned substantially overlapping or very close to each other, causing the heat conduction channels of the light sources to substantially overlap, which can easily lead to poor heat dissipation of the vehicle headlamp.

[0005] In addition, in the prior art, the light source is quickly connected to the power supply end through a cable, and the cable is in a high temperature environment, which poses a safety hazard.

[0006] Therefore, it is necessary to improve the traditional automobile headlights. Summary of the Invention

[0045] Description of the bracket 4: The bracket 4 is connected to the first end of the light source 1 and has a heat dissipation channel 5 leading to the light source 1. The bracket 4 is a circular structure, and the heat dissipation channel 5 is formed between the bracket 4 and the first end of the light source 1. The heat dissipation channel 5 extends to the light emitting point of the light source 1. Figure 2 、 Figure 7 As shown, the heat dissipation channel 5 starts from the inner hole of the bracket 4 and ends at Figure 1 The visual window ends at the visual window, and a protruding fin fish cover is provided at the visual window. When exhausting, the fin fish cover can let in more air, making the air flow rate of the heat dissipation channel 5 faster, thereby making the heat dissipation efficiency higher.

[0046] The plug 3 is installed at an angle to the heat dissipation module, and the plug 3 is electrically connected to the power supply circuit board. Preferably, the plug 3 is installed at a 90-degree angle to the heat dissipation module. The plug 3 has a plastic shell and two pins 36 provided on the plastic shell.

The outer end of the first waist cylinder 31 enters the interface 242 and is fixed. The outer surface of the first waist cylinder 31 and the second waist cylinder 32 form a step, and a single-opening socket cavity is formed inside. The closed end of the first waist cylinder 31 is installed and fixed with the two pins 36; the waisted surfaces on both sides of the second waist cylinder 32 are provided with a first undercut 33, and the flat surfaces on both sides are provided with a second undercut 34. The first undercut 33 is a triangular undercut, and its inclined surface faces the plug end. The second undercut 34 is a trapezoidal undercut with its slope facing the plug end. The plug 3 is stably connected to the power supply end of the vehicle body through the first undercut 33 and the second undercut 34, ensuring a stable electrical connection of the vehicle headlamp of the present invention and improving installation efficiency.
