Description

Technical Field

[0001] This utility model relates to the field of automotive lighting, specifically to an automotive LED marker light. Background Technology

[0002] In the automotive lighting field, LED marker lights have gradually replaced traditional halogen lamps as the mainstream configuration due to their advantages such as low energy consumption, long lifespan, and fast response speed. However, LED chips generate a lot of heat during operation. If heat cannot be dissipated effectively in time, the junction temperature of the LED chips will rise, leading to problems such as accelerated light decay, reduced luminous efficiency, and even component damage, seriously affecting the lifespan and lighting stability of the marker lights.

[0003] Currently, conventional automotive LED position lights rely solely on the heat sink fins on the surface of the lamp housing for passive heat dissipation. The heat sink fins have a simple structure, limited surface area, and poor air convection. Under conditions of long-term vehicle operation or high temperature, they are insufficient to meet the heat dissipation requirements of LED chips, thus requiring improvement. Utility Model Content

[0004] The purpose of this invention is to provide an automotive LED marker light to solve the problem of poor heat dissipation efficiency of conventional LED marker lights mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automotive LED marker light, comprising a connector, a lamp housing, a connecting sleeve, a lamp cover, and several aluminum substrates disposed within the connecting sleeve. The connecting sleeve contains a positioning frame for accommodating the aluminum substrates. A heat-conducting column is fixedly sleeved in the lamp housing, extending into the enclosed space of the several aluminum substrates to conduct heat generated by the aluminum substrates. A baffle is fixedly installed on the top of the respective heat-conducting column so that the baffle vibrates when the vehicle is moving, accelerating air convection and assisting in heat dissipation.

[0006] Preferably, the sidewall of the lamp housing is provided with a plurality of heat dissipation fins that are equidistantly distributed in a ring array.

[0007] Preferably, the outer wall of the spoiler is provided with an insulating layer.

[0008] Preferably, the positioning frame is a hollow frame that is adapted to the inner diameter of the connecting sleeve, and the periphery of the positioning frame is provided with a plurality of slots for accommodating the aluminum substrate.

[0009] Preferably, one end of the spoiler is fixedly connected to the lamp housing by spot welding, and the other end extends to be flush with the positioning frame.

[0010] Preferably, the heat-conducting column has an axial heat dissipation through hole inside, and the side wall of the heat-conducting column has a plurality of through holes.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention utilizes heat dissipation fins, heat-conducting columns, and baffles working together within the lamp body. The heat dissipation fins increase the surface area of ​​the lamp housing, while the heat-conducting columns, in conjunction with the baffles, accelerate air convection through vibration, rapidly dissipating the heat generated by the aluminum substrate. This reduces the operating temperature of the LED beads, minimizes light decay, and improves lighting stability. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4This utility model provides a technical solution: an automotive LED marker light, comprising a connector 1, a lamp housing 2, a connecting sleeve 3, a lamp cover 5, and several aluminum substrates 4 disposed within the connecting sleeve 3. The connector 1 is a standard automotive circuit interface, which can be directly connected to the power supply and control circuit of the vehicle body circuit. The side wall of the lamp housing 2 is provided with several heat dissipation fins 6 distributed in a circular array at equal intervals, effectively increasing the heat dissipation area and improving the heat dissipation efficiency of the marker light. The connecting sleeve 3 has a built-in positioning frame 9 for accommodating the aluminum substrates 4. The positioning frame 9 is a hollow frame adapted to the inner diameter of the connecting sleeve 3. The periphery of the positioning frame 9 is provided with several slots 10 for accommodating the aluminum substrates 4. The aluminum substrate 4, as the carrier of the LED lamp beads, is made of aluminum-based copper-clad laminate with a high thermal conductivity and its surface is treated with an immersion gold process to enhance the reliability of the electrical connection. Several aluminum substrates 4 are arranged in a circular and tightly packed manner in the slots 10 of the positioning frame 9 to form a high-efficiency light-emitting unit. The positioning frame 9 not only ensures stable support for the aluminum substrates 4 but also minimizes obstruction to airflow.

[0020] The connector 1 integrates a conductive metal sheet to ensure smooth current transmission to the lamp housing 2. Although the lamp housing 2 is made of aluminum alloy, it is connected to the heat-conducting column 7 through pre-embedded conductive lines. The heat-conducting column 7, made of copper with high thermal conductivity, also has a conductive function, further conducting the current to the positioning frame 9. Although the positioning frame 9 has a hollow frame structure, it has conductive contacts at the edge of the slot 10. When the aluminum substrate 4 is inserted into the slot 10, the circuit pads on the edge of the aluminum substrate 4 fit tightly with the conductive contacts of the positioning frame 9, thus forming a complete current transmission channel.

[0021] A heat-conducting column 7 is fixedly sleeved in the lamp housing 2. The heat-conducting column 7 extends into the enclosed space of several aluminum substrates 4. The heat-conducting column 7 has axial heat dissipation through holes inside and several through holes on the side wall of the heat-conducting column 7 to conduct heat generated by the aluminum substrates 4. A baffle 8 is fixedly installed on the top of the heat-conducting column 7. One end of the baffle 8 is fixedly connected to the lamp housing 2 by spot welding, and the other end extends to be flush with the positioning frame 9 so that the baffle 8 vibrates when the car is moving, accelerating air convection and assisting heat dissipation. The baffle 8 can be made of titanium foil, and the outer wall of the baffle 8 is provided with an insulating layer.

[0022] In this application, the heat dissipation fins 6, heat conduction pillars 7 and baffles 8 work together. The heat dissipation fins 6 increase the surface area of ​​the lamp housing 2, and the heat conduction pillars 7 and baffles 8 accelerate air convection through vibration, which quickly dissipates the heat generated by the aluminum substrate 4, thereby reducing the operating temperature of the LED beads, reducing light decay, and improving lighting stability.
