Description

Technical Field

[0001] This utility model belongs to the technical field of automotive lighting modules, and specifically relates to an automotive lighting module. Background Technology

[0002] The Automotive Headlight ADB (Adaptive Driving Beam) system is an advanced lighting system that uses advanced sensors, control units, and actuators to automatically adjust the beam range, brightness, and angle of the headlights based on factors such as vehicle driving status, road conditions, and weather conditions to adapt to different driving environments. The main components of an ADB system include sensors, control units, actuators, and the lighting system itself. A crucial component of the ADB lighting system is the lens module, which internally consists of a lens, a driver board, and LED chips. The core of the ADB module is an LED chip assembly composed of multiple LED arrays, externally equipped with multiple circuit control chips, with all commands implemented by the driver board.

[0003] Currently, most lamp lenses are installed using fasteners, which is very cumbersome, and the diffusion and focusing effects of the lenses are not good. Therefore, it is very important to obtain an automotive lighting module that overcomes the above defects. Utility Model Content

[0004] To solve at least one of the above-mentioned technical problems, this utility model provides an automotive lighting module, comprising:

[0005] The lamp driver board is provided with at least one light-emitting component;

[0006] The lens holder has at least one first through hole that mates with the light-emitting component;

[0007] The lens has at least one light diverging or converging portion, which is at least partially located in or passes through the first perforation to cooperate with the light-emitting component. The light diverging or converging portion forms a light incident surface on one side of the light-emitting component and a light exiting surface on the other side.

[0008] With the above technical solution, the light diverging or converging part of the lens passes through the first perforation and directly approaches the light-emitting component, that is, it is set close to the lamp bead, which can increase the light transmission effect.

[0009] The longitudinal section of the light diverging or converging part decreases from the light emitting surface to the light incident surface. The light emitting surface is a convex arc surface. The light diverging or converging part is truncated pyramidal in shape. There is a small gap between the light incident surface and the light-emitting component. This gap allows for thermal expansion and contraction and reduces light loss.

[0010] The lens and the lens holder are connected by a snap-fit ​​structure, which includes snap-fit ​​grooves and snap-fit ​​protrusions respectively disposed on the lens and the lens holder.

[0011] The above technical solution uses a snap-fit ​​connection for easy installation, simplifies installation steps and time, and increases the efficiency of mass production.

[0012] The lens holder is fixed to the lamp driver plate by fasteners, and at least one side of the lens holder has a heat dissipation notch between it and the lamp driver plate. A positioning block is provided on the lens holder, and a positioning notch that mates with the positioning block is provided on the lens. A heat sink is also included, fixedly connected to the lamp driver plate by fasteners, with the lens holder and the heat sink located on opposite sides of the lamp driver plate. A housing is also included, fixedly connected to the heat sink by fasteners, with at least one heat dissipation notch provided on the housing at the lamp driver plate location. A fan is also included, fixedly connected to the heat sink, with the fan and the lamp driver plate located on opposite sides of the heat sink.

[0013] The above settings can increase the heat dissipation effect. The light driver board of this utility model adopts an ADB module, which can control the brightness, turn off or on of each light-emitting component individually. Since the light diverging or converging part of the lens is close to the light-emitting component, the overall illumination range can be made more accurate and clearer.

[0014] It also includes an outer lens, which is connected to the housing via a second snap-fit ​​structure. The second snap-fit ​​structure includes snap-fit ​​spring arms located on the housing and the outer lens, and snap-fit ​​positions that cooperate with the snap-fit ​​spring arms. A limiting groove is formed on the outer wall of the outer lens, and a limiting block that cooperates with the limiting groove is formed on the inner wall of the housing.

[0015] Compared with the prior art, the advantages of this utility model are: the utility model has a simple structure, strong heat dissipation effect, and good light illumination effect. Attached Figure Description

[0031] To enable those skilled in the art to better understand this utility model and to more clearly define the scope of protection claimed by this utility model, the present utility model is described in detail below with reference to certain specific embodiments. It should be noted that the following are only some specific embodiments of the present utility model concept, and are only a part of the embodiments of this utility model. The specific and direct description of related structures is only for the convenience of understanding this utility model, and the specific features do not necessarily or directly limit the scope of implementation of this utility model.

[0032] Referring to the accompanying drawings, this utility model adopts the following technical solution: This utility model provides an automotive lighting module, comprising:

[0033] The lamp driver board 1 is provided with at least one light-emitting component 101;

[0034] The lens holder 2 has at least one first through hole that mates with the light-emitting component 101;

[0035] Lens 3 is provided with at least one light diverging or converging part 301. The light diverging or converging part 301 is at least partially located in or passes through the first perforation to cooperate with the light-emitting component 101. The light diverging or converging part 301 forms a light incident surface 303 on one side of the light-emitting component 101 and a light exiting surface 302 on the other side.

[0036] Through the above technical solution, the light diverging or converging part 301 of the lens 3 passes through the first perforation and directly approaches the light-emitting component 101, that is, it is set close to the lamp bead, which can increase the light transmission effect.

[0037] The longitudinal section of the light diverging or converging portion 301 decreases from the light emitting surface 302 to the light incident surface 303. The light emitting surface 302 is a convex arc surface 304. The light diverging or converging portion 301 is frustum-shaped. There is a gap 4 between the light incident surface 303 and the light-emitting component 101. The gap 4 is small, which can accommodate thermal expansion and contraction, and the small gap 4 can reduce light loss.

[0038] The lens 3 and the lens support 2 are connected by a snap-fit ​​structure, which includes a snap-fit ​​groove 501 and a snap-fit ​​protrusion 502 respectively disposed on the lens 3 and the lens support 2.

[0039] The above technical solution uses a snap-fit ​​connection for the lens 3, which facilitates installation, simplifies installation steps and time, and increases the efficiency of mass production.

[0040] The lens bracket 2 is fixed to the lamp driver board 1 by fasteners, and at least one side of the lens bracket 2 has a heat dissipation notch 6 between it and the lamp driver board 1. A positioning block 701 is provided on the lens bracket 2, and a positioning notch 702 that mates with the positioning block 701 is provided on the lens 3. A fan 9 is also included, which is fixedly connected to the lamp driver board 1 by fasteners. The lens bracket 2 and the fan 9 are respectively located on opposite sides of the lamp driver board 1. A housing 8 is also included, which is fixedly connected to the fan 9 by fasteners. At least one heat dissipation notch 801 is provided on the housing 8 at the lamp driver board 1. The fan 9 is also included, which is fixedly connected to itself. The fan 9 and the lamp driver board 1 are respectively located on opposite sides of the fan 9.

[0041] The above settings can increase the heat dissipation effect. The light driver board of this utility model adopts an ADB module, which can control the brightness, turn off or on of each light-emitting component 101 individually. Since the light diverging or converging part 301 of the lens 3 is close to the light-emitting component 101, the overall illumination range can be made more accurate and clearer.

[0042] It also includes an outer lens 11, which is connected to the outer casing 8 via a second snap-fit ​​structure. The second snap-fit ​​structure includes a snap-fit ​​spring arm 1201 disposed on the outer casing 8 and the outer lens 11, and a snap-fit ​​position 1202 that cooperates with the snap-fit ​​spring arm 1201. A limiting groove 1301 is formed on the outer wall of the outer lens 11, and a limiting block 1302 that cooperates with the limiting groove 1301 is formed on the inner wall of the outer casing 8.

[0043] Compared with the prior art, the advantages of this utility model are: the utility model has a simple structure, strong heat dissipation effect, and good light illumination effect.

However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
