Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] Figure 1 This is a schematic diagram of the structure of a heat sink according to an embodiment of this application.

[0021] like Figure 1 As shown, the radiator includes a high beam / low beam radiator 14 and an ADB radiator 15, wherein the high beam / low beam radiator 14 and the ADB radiator 15 have a heat transfer end and a heat dissipation end, respectively.

[0022] The heat transfer end of the high and low beam heat sink 14 is used to contact the high and low beam printed circuit board assembly. The heat transfer end of the ADB heat sink 15 is used to contact the ADB printed circuit board assembly. The heat dissipation ends of the high beam / low beam radiator 14 and the ADB radiator 15 are staggered to form an inclined airflow path, which lengthens the airflow path and enhances the heat dissipation effect.

[0023] The heat dissipation ends of the high beam / low beam radiator 14 and the heat dissipation ends of the ADB radiator 15 are staggered in the horizontal and / or vertical directions.

[0024] The fact that the heat dissipation ends of the high beam / low beam radiator 14 and the ADB radiator 15 are arranged in a staggered manner in the horizontal direction means that the heat dissipation ends of the high beam / low beam radiator 14 and the ADB radiator 15 are not on the same horizontal line.

[0025] The fact that the heat dissipation ends of the high beam / low beam radiator 14 and the ADB radiator 15 are arranged in a vertically staggered manner means that the heat dissipation ends of the high beam / low beam radiator 14 and the ADB radiator 15 are not on the same vertical line.

[0026] Figure 2 This is a schematic diagram of a heat dissipation module according to an embodiment of this application. A side view of the heat dissipation module is shown below. Figure 3 As shown.

[0027] like Figure 2 As shown, the heat dissipation module may include: high and low beam PCBA 12, ADB PCBA 13, high and low beam heat sink 14, ADB heat sink 15, and module bracket ( Figure 2 (Not shown in the image), fan 17 and air guide shroud 18, the high beam and low beam radiator 14 and the ADB radiator 15 respectively have a heat transfer end and a heat dissipation end.

[0028] The heat transfer end of the high and low beam heat sink 14 is used to contact the high and low beam printed circuit board assembly 12.

[0029] The heat transfer end of the ADB heat sink 15 is used to contact the ADB printed circuit board assembly 13.

[0030] The high and low beam heat sink 14, the ADB heat sink 15, the fan 17, and the air guide shroud 18 are fixedly connected to the module bracket.

[0031] The heat dissipation ends of the high and low beam radiator 14 and the ADB radiator 15 are arranged in a staggered manner, and the fan 17 and the air guide shroud 18 are respectively arranged at an angle.

[0032] The inclined arrangement of the fan 17 means that the fan 17 is inclined relative to the heat dissipation ends of the high / low beam radiator 14 and the ADB radiator 15, that is, the fan 17 forms a certain tilt angle with the vertical direction. Similarly, the inclined arrangement of the air guide shroud 18 means that the air guide shroud 18 is inclined relative to the heat dissipation ends of the high / low beam radiator 14 and the ADB radiator 15, that is, the air guide shroud 18 forms a certain tilt angle with the vertical direction. This arrangement reduces the obstruction of airflow by the radiators and increases the airflow path length, thus improving the heat dissipation effect.

[0033] The fan 17 is located near the lower heatsink of the high and low beam radiator 14 and the ADB heatsink 15, and is used to blow air at an angle upward. Since the hot airflow itself also flows upward, the fan 17 can blow air in the direction of the hot airflow, so as to make the heat dissipation efficiency higher.

[0034] The high and low beam heat sink 14 and the high and low beam printed circuit board assembly 12 together form the high and low beam module, and the ADB heat sink 15 and the ADB printed circuit board assembly 13 together form the ADB module. The light source of both the high and low beam module and the ADB module is an LED (Light Emitting Diode). During the light emission process, the electrical energy that is not converted into light energy is dissipated in the form of heat energy. Therefore, the LED light source is the heat source of the system. The LED is fixed on the corresponding PCBA board by surface mount technology. The PCBA is equipped with a heat sink to achieve passive heat dissipation through heat conduction. In addition, the inclined fan 17 and the air guide shroud 18 together form an active heat dissipation device to achieve convection exchange of heat between the heat sink fins and the air, carrying away the heat on the heat sink, thereby achieving the effect of cooling the light source LED and other electronic components on the PCBA.

[0035] The heat dissipation end of the high beam / low beam radiator 14 has fins, and the fins of the high beam / low beam radiator 14 are arranged at an angle or flush. And / or, the heat dissipation end of the ADB radiator 15 has fins, and the fins of the ADB radiator 15 are arranged at an angle or flush.

[0036] Figure 4 This is a schematic diagram of a heat sink fin according to an embodiment of this application. The fins of the high / low beam heat sink 14 and / or the fins of the ADB heat sink 15 can both be... Figure 4 The structure shown.

[0037] like Figure 4As shown, the fins 25 of the high / low beam radiator 14 and / or the ADB radiator 15 extend in the z-direction (the height direction of the headlight module or the vehicle body) and are arranged at an angle. This arrangement increases the heat dissipation area, and the angled fins match the airflow direction of the angled fan, reducing wind resistance and improving convection efficiency.

[0038] Figure 5 This is a schematic diagram of another heat sink fin configuration according to an embodiment of this application. The fins of the high / low beam heat sink 14 and / or the fins of the ADB heat sink 15 can both be... Figure 5 The structure shown.

[0039] like Figure 5 As shown, the fins 25 of the high beam / low beam radiator 14 and / or the ADB radiator 15 extend in the z-direction and are arranged flush. This arrangement reduces wind resistance, is easy to maintain, and has high space adaptability.

[0040] For example, the angle between the rotation axis of the fan 17 on the air guide shroud 18 and the vertical direction is between 10 degrees and 30 degrees, thereby improving heat dissipation efficiency. The specific arrangement can be made according to the space inside the lamp.

[0041] For example, the rotation axis of the fan 17 on the air guide shroud 18 makes an angle of 20.5 degrees with the vertical direction. Experiments have verified that this angle can balance the airflow coverage and wind resistance, thereby improving heat dissipation efficiency to a greater extent.

[0042] For example, the fan 17 is either an axial fan or a turbine fan. Axial fans have a large air volume and are suitable for low-resistance scenarios. Turbine fans have high air pressure and are suitable for airflow in compact spaces. The specific choice can be made flexibly according to the space inside the lamp.

[0043] Optionally, the high and low beam heat sink 14 and / or the ADB heat sink 15 can be made of pure aluminum, aluminum alloy, or stainless steel, and the process can be die casting, stamping, forging, etc., which can be selected according to the overall lamp thermal simulation and weight budget requirements.

[0044] Optionally, the air guide shroud 18 can be made of PBT (polybutylene terephthalate), which is high temperature resistant, flame retardant, lightweight, and low cost.

[0045] Optionally, a guide plate is provided inside the air guide shroud 18 to optimize airflow distribution, reduce turbulence, and ensure that the airflow passes evenly through the heat sinks of each module, thus avoiding local overheating.

[0046] In this embodiment, the arrangement of the active heat dissipation device is optimized based on the multi-module structure. The arrangement of the fan and air guide is at a certain tilt angle with the module to reduce the obstruction of the lower module and increase the airflow path length, thereby improving the heat dissipation effect.

[0047] Figure 6 This is a schematic diagram of the structure of a vehicle lighting module according to an embodiment of this application.

[0048] like Figure 6 As shown, the headlight module may include: high and low beam lenses 1, ADB outer lens 2, and a light-blocking plate ( Figure 6 The light-blocking partition is not shown in the figure (it will be shown in the following figures) and the lens bracket 3.

[0049] The high / low beam lens 1 is an optical lens that integrates high beam and low beam functions. It should be noted that a baffle can be incorporated into the integrated high / low beam lens 1. The baffle is a crucial component for switching between high and low beams. When in low beam mode, the baffle blocks part of the light, altering the reflection and refraction paths, causing the light to be projected onto the road surface in a low beam illumination mode. This typically forms a light spot with a specific cutoff line, preventing excessive upward or oncoming lane dispersion and avoiding glare for drivers of oncoming vehicles. When in high beam mode, the baffle, in conjunction with the lens system, projects light onto a specific area according to design requirements, achieving a good lighting effect.

[0050] The ADB outer lens 2 is an optical lens that can automatically adjust the high beam illumination range based on vehicle sensor information to prevent glare from oncoming or same-direction vehicles and meet adaptive high beam requirements.

[0051] The high / low beam lens 1 and the ADB external lens 2 are respectively fixedly connected to the lens bracket 3. The lens bracket 3 is a one-piece structure, so there will be no large gap between the high / low beam lens 1 and the ADB external lens 2, making the space more compact. In implementation, the high / low beam lens 1 and the ADB external lens 2 can be fixedly connected to the lens bracket 3 by any suitable method such as clips or screws.

[0052] The light-blocking partition is located between the high / low beam lens 1 and the ADB outer lens 2, and is used to at least partially isolate the high / low beam lens 1 and the ADB outer lens 2. The light-blocking partition can prevent the light emitted by the high / low beam lens 1 from interfering with the light emitted by the ADB outer lens 2. In implementation, the light-blocking partition can be fixed to the lens bracket 3 by any suitable means such as clips or screws, or it can be fixed to other components (such as the module decorative frame below) by any suitable means such as clips or screws.

[0053] In this embodiment, the high and low beam lenses and the ADB external lens can be integrated into an integrated physical module through the lens bracket with an integrated structure. Compared with the combination of multiple independent physical modules, this integrated physical module has multiple functions, is compact, and has a smaller size, thus reducing the space occupied by the headlight module and providing greater design freedom for the headlight styling design.

[0056] The headlight module may also include a cover plate 5, a glass plate 6, and a module decorative frame 7, wherein the module decorative frame 7 is an integral structure. The glass plate 6 is disposed within the module decorative frame 7, and the cover plate 5 is fixed to the module decorative frame 7. The cover plate 5 and the module decorative frame 7 clamp the glass plate 6, and the module decorative frame 7 surrounds the high / low beam lens 1 and the ADB outer lens 2. The cover plate 5 can be a glass cover. The cover plate 5 protects the optical and electronic components inside the headlight module and has a certain degree of optical transparency to ensure that light can pass through normally. The glass plate 6, as an optical element, reflects or refracts light, helping to adjust the direction and distribution of light for better illumination. The module decorative frame 7 decorates and enhances the appearance of the headlight module and also provides structural support to ensure the stability of the internal components.

[0057] The headlight module may further include a high / low beam concentrator 8 and a high / low beam concentrator bracket 9.

The ADB inner lens 10 is located at the rear end of the ADB outer lens 2. The high / low beam concentrator 8 is used to focus and adjust the light in high / low beam states, ensuring that the light can be effectively concentrated before emission, thus improving the lighting effect. The ADB inner lens 10 is used to focus and adjust the light in ADB state, ensuring that the light can be effectively concentrated before emission, thus improving the lighting effect. The ADB inner lens can be an ADB concentrator or an ADB silicone inner lens.

[0058] The headlight module may further include a high / low beam PCBA 12, on which a high / low beam light source is disposed.

And / or, the headlight module may further include an ADB PCBA 13, on which an ADB light source is disposed. The ADB PCBA 13 is fixedly connected to the ADB inner lens bracket 11 and is located at the rear end of the ADB inner lens 10. The high / low beam PCBA 12 is used to control the switching of high and low beams and brightness adjustment, achieving light control through electronic components. The ADB PCBA 13 is used to control the operation of the ADB system, achieving adaptive light control through electronic components.

[0059] The headlight module may further include a high / low beam heat sink 14, with the high / low beam PCBA 12 fixed to the high / low beam heat sink 14, and the high / low beam heat sink 14 located at the rear end of the high / low beam PCBA 12. And / or, the headlight module may further include an ADB heat sink 15, with the ADB PCBA 13 fixed to the ADB heat sink 15, and the ADB heat sink 15 located at the rear end of the ADB PCBA 13.

[0060] The headlight module may also include a module bracket 16, a fan 17, and an air guide 18. The lens bracket 3, the fan 17, and the air guide 18 are respectively fixed to the module bracket 16.

It should be noted that, depending on the ADB implementation method, the ADB intermediate lens 19 can be set or not.

[0089] (7) Secure the third and fourth assemblies to the sixth assembly using any suitable method such as clips or screws to form the seventh assembly. A schematic diagram of the seventh assembly is shown below. Figure 24 As shown.

[0090] (8) The fifth assembly, the seventh assembly, the fan 17, and the air guide 18 are fixed to the module bracket 16 by any suitable method such as clips or screws to form the vehicle light module. A three-dimensional schematic diagram of the vehicle light module is shown below. Figure 25 As shown. A cross-sectional view of the vehicle headlight module is shown below. Figure 26 As shown. Another cross-sectional view of the headlight module is shown below. Figure 27 As shown in the diagram. A cross-sectional view of the headlight module is shown below. Figure 28 As shown, it includes high and low beam baffles 23. It should be noted that the rotation axis of the fan 17 on the air guide shroud 18 and the Z-axis angle are between 10-30°, with 20.5° recommended.

[0091] For example, the high and low beam lens 1 can be an ellipsoidal lens, the ellipsoidal shape of which helps to focus and reflect light, ensuring good illumination at both long and short distances. The high and low beam lens 1 integrates the high and low beams, separated by a baffle. The material of the high and low beam lens 1 can be selected to have a high Abbe coefficient, such as K9 optical glass. To improve optical efficiency, the high and low beam lens 1 can be coated with anti-reflection coatings on one or both sides to increase light transmittance. The surface of the high and low beam lens 1 can achieve a diffusion effect through an array of square or rhomboid patterns, and local protrusions can achieve three-zone illumination supplementation.

[0092] For example, the ADB outer lens 2 can be an ADB ellipsoidal lens. The ellipsoidal shape helps to focus and reflect light, ensuring good illumination at both long and short distances. The ADB outer lens 2 can employ a multi-layered (e.g., two or three layers) ellipsoidal structure, which are combined to form an external projection system. The surface can achieve a diffusion effect through an array of square or rhomboid patterns to achieve better uniformity. The material of the ADB outer lens 2 can be a high Abbe coefficient material, such as K9 optical glass. PC (Polycarbonate) and PMMA (Polymethyl Methacrylate) materials can also be used. To improve optical efficiency, one or both sides of the ADB outer lens 2 can be coated with an anti-reflective coating.

[0093] For example, to ensure good optical performance, the glass plate 6 can be made of a high Abbe coefficient material, such as K9 optical glass. To improve optical efficiency, the glass plate 6 can be coated with anti-reflective coatings on one or both sides. Anti-reflective coatings on both sides of the glass plate 6 can reduce ghosting caused by parallel surfaces during imaging. If the goal is to improve the effect of a deep lens when the lens is not illuminated, the glass plate 6 can also be coated with an anti-reflective coating.

[0094] For example, to improve the overall system's heat dissipation and provide more flexible light source selection, the ADB inner lens 10 can be made of silicone. Of course, other optical materials with high Abbe coefficients can also achieve the same function, such as materials with Abbe coefficients of 50-60. The ADB inner lens 10 can be connected to the light guide teeth. Through the modulation of total internal reflection within the light guide teeth, the large-angle light emitted by the LED light source is coupled into the ADB inner lens 10 with a small divergence angle, serving as the object plane in the projection system. This is then projected to infinity on the image side through two to three outer glass lenses (such as the ADB outer lens and the ADB intermediate lens), producing an illumination effect that functions as a car's high beam. The number of light guide teeth can be set according to actual needs; this embodiment does not limit this. Considering the anti-glare road illumination effect and cost, a total of 42 light guide teeth (2 rows * 21 columns) is recommended.

[0095] The large-angle light rays from the LED, which are not received by the light guide teeth on the ADB inner lens 10, will cause light leakage. Therefore, a perforated baffle matching the light guide teeth can be installed around the light guide teeth to prevent this. Figure 29 The perforated baffle 24 shown is used to block and avoid interference with the ADB optical guide teeth. The perforated baffle 24 can be made of metal, various other plastics or absorbing materials, and can be black or other colors. There are no restrictions on the horizontal and vertical dimensions. For example, the horizontal dimension can be 40~100mm (47mm recommended) and the vertical dimension can be 5~50mm (9.2mm recommended). The recommended equivalent size for optical effect is 47mm*6mm.

[0096] High and low beam lenses, as well as ADB outer lenses, ADB intermediate lenses, and ADB inner lenses (or flat glass), can achieve a uniform light pattern by creating diamond / square patterns on their outer surfaces. Furthermore, the uniformity of the headlight module can be achieved through defocusing (the surface connecting the silicone inner lens and the light guide teeth is not at the focal plane of the projection lens system) and shorter light guide tooth lengths (shorter light guide teeth result in less total internal reflection modulation of the light angle). Pattern radial dimensions of 0.3~1.5mm (0.4*0.4mm diamond pattern recommended for high and low beam lenses, 1*1mm square pattern recommended for ADB outer lenses) are all acceptable. In addition, the coordination between the light guide teeth and the light source (LED, bulb, etc.) can also control the energy distribution of the projected pixels in each unit composed of the light source and the light guide teeth. The main adjustment items are: the angle (0~10°) between the light guide tooth incident surface and the light source emitting surface, and whether the light guide tooth incident surface is larger, more matched, or smaller than the light source emitting surface (area deviation: ±20mm). 2 It is recommended that the light-incident surface of the silicone optical guide teeth be a 1*1mm square.

[0097] The arrangement length of each light guide tooth on the inner surface of the silicone inner lens of the ADB can be achieved by multiplying the sine value of the angle of the system diffusion angle (pattern diffusion angle + defocus diffusion angle) by the field of view angle of each illumination pixel by the focal length of the projection system. Focal lengths of 40~120mm are all acceptable, but 60-85mm is recommended.

[0098] Monochromatic aberrations of a lens system, such as spherical aberration, coma, and distortion, can be optimized through parameters such as lens shape, thickness, and spacing. Field curvature can be corrected through the surface design of the ADB inner lens (reverse image plane). System chromatic aberration can be optimized by using a combination of positive and negative dispersive materials in the lens.

[0099] Tolerances generated during the production of automotive lighting modules, such as lens surface machining errors, thickness errors, and installation eccentricity, can be considered in the design phase using Zemax software.

[0100] In the production line dimming process, the system can be divided into a projection module consisting of two outer glass lenses embedded in a lens holder, and an image module consisting of an ADB inner lens (integrated with the light guide teeth), a PCBA, and a heat sink. These three components are connected by a fine-tuning bracket and screws. The PCBA, heat sink, and lens holder are equipped with oval holes (7.5mm in length) to enable dimming in the X, Y, and Z directions. An industrial camera is used to identify the angular boundaries and edge sharpness of the central LED imaging pixels to determine if the image module is correctly assembled.

[0101] The module's functionality can be further adjusted by modifying the glass lens surface type (spherical, second-order aspherical, higher-order aspherical, etc.), thickness (5~45mm), spacing (3~80mm), inner lens surface type (spherical, second-order aspherical, higher-order aspherical, etc., with concentric curved surfaces recommended for the front and rear surfaces), thickness (1~10mm, 2-5mm recommended), and the surface type (planar, curved) of the five surfaces of the optical guide teeth.

[0102] For example, the light-blocking partition 4 can be made of a material with certain strength and light-blocking properties to ensure that it can stably play its light-blocking role and maintain stable performance in the high-temperature environment inside the vehicle headlight without deformation or damage.

[0103] For example, the fan 17 may be an axial fan or a turbo fan, etc.

[0104] In this embodiment, the vehicle headlight module integrates high beam, low beam, and adaptive high beam functions. The module is small in size, highly integrated, and facilitates platform-based promotion and miniaturized, refined design. The lateral and longitudinal dimensions of the lens can be limited to the range of 60-100mm.
