[0071] 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.

[0072] Figure 1 is a structural schematic diagram of a vehicle lighting module according to an embodiment of this application.

[0073] In this embodiment, the headlight module includes: a high / low beam module, an adaptive high beam (ADB) module, and a bracket module; the high / low beam module and the adaptive high beam (ADB) module are respectively fixedly connected to the bracket module. Thus, the high / low beam module and the adaptive high beam (ADB) module can be integrated into the same physical module via the bracket module. Compared to multiple independent physical modules, this approach integrates multiple functions, is more compact, and has a smaller size, thereby reducing the space occupied by the headlight module and providing greater design freedom for the headlight's styling.

[0074] For example, in the embodiments of this application, the high / low beam module typically includes low beam illumination and high beam illumination. The low beam illumination provides illumination for a shorter distance in front of the vehicle, while the high beam illumination provides illumination for a longer distance and with higher brightness, thereby expanding the driver's field of vision in darker environments. The adaptive high beam (ADB) module is an intelligent upgrade on top of the basic high beam, used to dynamically control certain areas of the basic high beam. While avoiding glare, it can intelligently enhance the illumination of certain areas, such as the inside of curves, areas with pedestrians or obstacles, etc.

[0075] In this embodiment, the bracket module provides a robust and precise mounting position and interface for the high and low beam modules and the ADB module, integrating them into a stable whole. This also ensures that the optical axes of the high and low beam modules and the ADB module, i.e. the center direction of light emission, have high relative positional accuracy and stability.

[0076] As shown in Figure 1, the vehicle headlight module may include: high and low beam lenses 1, ADB outer lens 2, light-blocking partition (the light-blocking partition is not shown in Figure 1, but will be shown in subsequent figures) and lens bracket 3.

[0077] The high / low beam lens 1 is an optical lens that integrates high beam and low beam. It should be noted that a baffle can be installed in the high / low beam lens 1. The baffle is an important component for switching between high and low beams. When in low beam mode, the baffle blocks part of the light, changing the reflection and refraction path of the light, so that the light is projected onto the road surface in a low beam illumination mode. This typically forms a light spot with a specific cutoff line, preventing the light from excessively diffusing upwards or into the oncoming lane, thus avoiding glare for drivers of oncoming vehicles. When in high beam mode, the baffle, in conjunction with the lens system, projects the light onto a specific area according to design requirements, achieving a good lighting effect.

[0078] 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.

[0079] 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 integrates the high / low beam lens 1 and the ADB external lens 2 into the same physical module, thus eliminating large gaps between them and 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 using any suitable method such as clips or screws.

[0080] 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.

[0081] In this embodiment, the high and low beam lenses and the ADB external lens can be integrated into the same physical module through the lens bracket. Compared with the combination of multiple independent physical modules, it integrates 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.

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 plate, used to protect the optical and electronic components inside the headlight module, while also having a certain degree of optical transparency to ensure that light can pass through normally. The glass plate 6, as an optical element, is used to reflect or refract light, helping to adjust the direction and distribution of light for better illumination. The module decorative frame 7 is used to decorate and beautify the appearance of the headlight module, and also provides structural support to ensure the stability of the internal components.

[0086] The headlight module may further include a high / low beam concentrator 8 and a high / low beam concentrator bracket 9. The high / low beam concentrator 8 is fixed to the high / low beam concentrator bracket 9, and the high / low beam concentrator bracket 9 is fixedly connected to the lens bracket 3. The high / low beam concentrator 8 is located at the rear end of the high / low beam lens 1. And / or, the headlight module may further include an ADB inner lens 10 and an ADB inner lens bracket 11. The ADB inner lens 10 is fixed to the ADB inner lens bracket 11, and the ADB inner lens bracket 11 is fixedly connected to the lens bracket 3. 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 is 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 is effectively concentrated before emission, thus improving the lighting effect. The ADB inner lens can be an ADB concentrator or an ADB silicone inner lens.

[0087] The headlight module may further include a high / low beam PCBA (Printed Circuit Board Assembly) 12, on which high / low beam light sources are disposed. The high / low beam PCBA 12 is fixedly connected to the high / low beam concentrator bracket 9 and is located at the rear end of the high / low beam concentrator 8. 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.

[0088] The headlight module may further include a high / low beam heat sink 14, to which the high / low beam PCBA 12 is fixed, with the high / low beam heat sink 14 located at the rear end of the high / low beam PCBA 12.

[0089] 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. The fan 17 and the air guide 18 are located at the rear end of the module bracket 16. The fan 17 is used for forced cooling, carrying away heat generated inside the headlight module through airflow. The air guide 18 is used to guide airflow, helping the radiator to dissipate heat more effectively.

[0090] Figure 2 also includes an ADB intermediate lens 19, which is located at the rear end of the ADB outer lens. It should be noted that, depending on the ADB implementation method, the ADB intermediate lens 19 can be optionally included or omitted.

Another cross-sectional view of the headlight module is shown in Figure 22. A cross-sectional schematic diagram of the headlight module is shown in Figure 23, which includes the high and low beam baffles 23. It should be noted that the rotation axis of the fan 17 on the air guide 18 and the Z-axis angle are between 10-30°, with 20.5° recommended.

[0121] 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.

[0122] 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.

[0123] 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.

[0124] 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 Emitting Diode) 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 light 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.

[0125] The large-angle light rays from the LEDs not received by the light guide teeth on the ADB inner lens 10 can cause light crosstalk. Therefore, a perforated baffle matching the light guide teeth can be installed around the light guide teeth. This is achieved by using the perforated baffle 24, as shown in Figure 24, to block and avoid light crosstalk. 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 its horizontal and vertical dimensions; for example, a horizontal dimension of 40–100 mm (47 mm recommended) and a vertical dimension of 5–50 mm (9.2 mm recommended) are acceptable. The recommended optical equivalent size is 47 mm * 6 mm.

[0126] 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), ranging from 0.3 to 1.5 mm (0.4*0.4 mm diamond patterns are recommended for high and low beam lenses, and for ADB outer lenses...). For lenses, a 1*1mm square pattern is recommended, and the radial dimensions of the pattern are acceptable. In addition, the combination of the light guide teeth and the light source (LED, bulb, etc.) can also control the energy distribution of the projected pixels of each unit composed of light sources and light guide teeth. The main adjustment items are: the angle (0~10°) between the light-incident surface of the light guide teeth and the light-emitting surface of the light source, and the design of the light-incident surface of the light guide teeth being larger, more matched, or smaller than the light-emitting surface of the light source (area deviation: ±20mm2). It is recommended that the light-incident surface of the silicone light guide teeth be a 1*1mm square.

[0127] 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 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.

[0128] 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.

[0129] 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.

[0130] In the production line dimming process, the system can be divided into a projection module consisting of two outer glass lenses (ADB outer lens and ADB intermediate lens), which is embedded in the 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 achieve 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 whether the image module is assembled in the correct position.

[0131] 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, with 2-5mm recommended), and the surface type (planar, curved) of the five surfaces of the optical guide teeth.

[0132] 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.

[0133] For example, the fan 17 may be an axial fan or a turbo fan, etc.

[0134] 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 60–100 mm.

[0135] Figure 1A is a structural schematic diagram of another vehicle light module according to an embodiment of this application.

[0136] As shown in Figure 1A, the vehicle headlight module may include: ADB projection module 1, ADB image module 2, and fine-tuning bracket 3.

[0137] The ADB projection module 1 is connected to the fine-tuning bracket 3 via a first locking component (not shown in Figure 1A).

[0138] The ADB image module 2 is connected to the fine-tuning bracket 3 via a second locking component (not shown in Figure 1A).

[0139] Both the first locking component and the second locking component are adjustable locking components.

[0140] In this embodiment, both the ADB projection module 1 and the ADB image module 2 are connected to the fine-tuning bracket 3 through an adjustable locking component. Based on the fine-tuning bracket 3, the relative positions of the ADB projection module 1 and the ADB image module 2 can be adjusted, thereby achieving precise dimming of the light signal and ensuring that the light signal emitted by the ADB image module 2 is accurately projected through the ADB projection module 1.

[0141] In one optional embodiment, the first locking component includes an X-axis locking component, and the second locking component includes Y-axis and Z-axis locking components. That is, the ADB projection module 1 is connected to the fine-tuning bracket 3 via the X-axis locking component, and the ADB image module 2 is connected to the fine-tuning bracket 3 via the Y-axis and Z-axis locking components. The adjustable locking components in the X, Y, and Z directions allow for dimming in all three directions. After dimming, the X, Y, and Z locking components can be locked. Each locking component can be a locking screw.

[0142] Among them, X direction refers to the length direction of the headlight module or the vehicle body, Y direction refers to the width direction of the headlight module or the vehicle body, and Z direction refers to the height direction of the headlight module or the vehicle body.

[0143] In one alternative embodiment, the X-axis locking component has hook structures on both sides, which cooperate with the dimming fixture to achieve rapid positioning and clamping.

[0144] In one alternative embodiment, the X-axis locking components are arranged on the side wall of the fine-tuning bracket. Specifically, four X-axis locking components may be provided, symmetrically arranged on the side wall of the fine-tuning bracket.

[0145] In one optional embodiment, the Y-axis and Z-axis locking components are arranged on the back side of the fine-tuning bracket. Specifically, four Y-axis and Z-axis locking components can be provided, symmetrically arranged on the back side of the fine-tuning bracket. The back side of the fine-tuning bracket refers to the side facing the ADB image module 2.

[0146] In one optional embodiment, the top of the fine-tuning bracket 3 is provided with fins, which can be Z-shaped fins. The fins can increase the strength of the fine-tuning bracket on the one hand, and do not block the airflow of the fan on the other hand. By increasing the heat dissipation area, the heat dissipation can be accelerated, which helps the vehicle light module to maintain a suitable operating temperature range and ensures the stable operation of the vehicle light module.

[0147] In one optional embodiment, the fine-tuning bracket 3 is provided with reinforcing ribs to improve the deformation resistance of the fine-tuning bracket 3 and prevent the fine-tuning bracket 3 from shifting due to force during the dimming process.

[0148] In one optional embodiment, the fine-tuning bracket 3 is provided with a positioning structure for mounting the ADB projection module 1, for achieving initial rapid and accurate positioning of the ADB projection module 1 during installation; and / or, the fine-tuning bracket 3 is provided with a positioning structure for mounting the ADB image module 2, for achieving initial rapid and accurate positioning of the ADB image module 2 during installation. The positioning structure can be a positioning hole, a positioning slot, etc.

[0149] Figure 2A is a structural schematic diagram of a fine-tuning bracket according to an embodiment of this application.

[0150] As shown in Figure 2A, the fine-tuning bracket has pre-drilled X-direction locking screw holes 301, Y-direction and Z-direction locking screw holes 302, and fins 303. Four of the X-direction locking screw holes 301 are located on the side wall of the fine-tuning bracket 3, while four of the Y-direction and Z-direction locking screw holes 302 are located on the back of the fine-tuning bracket 3. All four of the Y-direction and Z-direction locking screw holes 302 can achieve both Y-direction and Z-direction locking. The X-direction locking component is inserted into the X-direction locking screw hole for locking, and the Y-direction and Z-direction locking components are inserted into the Y-direction and Z-direction locking screw holes for locking.

[0151] In one optional embodiment, the ADB projection module 1 includes an ADB outer lens, an ADB intermediate lens, and a lens bracket. The ADB outer lens and the ADB intermediate lens are respectively fixed on the lens bracket. The distance between the ADB outer lens and the ADB light source is greater than the distance between the ADB intermediate lens and the ADB light source, that is, the light emitted from the ADB light source first passes through the ADB intermediate lens and then through the ADB outer lens.

[0152] In this approach, the ADB projection module 1, by incorporating two or more layers of lenses, can improve the precision of light convergence and / or divergence control, reduce aberrations, enhance optical efficiency, and increase design flexibility. For example, a single lens has limited refractive power, making it difficult to precisely shape the ADB high beam pattern. Two layers of lenses, however, can perform secondary refraction; by rationally designing the curvature, thickness, and relative position of the two lenses, the convergence and / or divergence of light can be controlled more accurately. A single lens can hardly correct multiple aberrations simultaneously; two layers of lenses can correct different types of aberrations separately through different material selections and optical designs. Two layers of lenses can better match the light characteristics output by the ADB image module, improving light utilization.

[0153] Figure 3A is a schematic diagram of the structure of an ADB projection module according to an embodiment of this application.

[0154] As shown in Figure 3A, the ADB projection module includes an ADB outer lens 101, an ADB intermediate lens 102, and a lens bracket 103. The ADB outer lens 101 and the ADB intermediate lens 102 are respectively fixed on the lens bracket 103.

[0155] In one alternative embodiment, the ADB outer lens 101 and / or the ADB intermediate lens 102 are coated with an anti-reflection film, thereby reducing the component of reflected light at the interface and increasing the system's light energy utilization rate.

[0156] The ADB outer lens 101 includes an outer surface and an inner surface. The outer surface of the ADB outer lens 101 refers to the light-emitting surface of the ADB outer lens 101, and the inner surface of the ADB outer lens 101 refers to the light-incident surface of the ADB outer lens 101.

[0157] For example, both the outer surface and the inner surface of the ADB outer lens 101 are coated with an anti-reflection film, thereby reducing reflection loss to a greater extent.

[0158] For example, the outer surface of the ADB outer lens 101 is provided with a pattern to achieve a uniform light pattern. In this case, the outer surface of the ADB outer lens 101 is uncoated, and the inner surface of the ADB outer lens 101 is coated with an anti-reflective film.

[0159] The ADB intermediate lens 102 includes an outer surface and an inner surface. The outer surface of the ADB intermediate lens 102 refers to the light-emitting surface of the ADB intermediate lens 102, and the inner surface of the ADB intermediate lens 102 refers to the light-incident surface of the ADB intermediate lens 102.

[0160] For example, both the outer surface and the inner surface of the ADB intermediate lens 102 are coated with an anti-reflection film, thereby reducing reflection loss to a greater extent.

[0161] For example, the anti-reflective coating on the inner surface of the ADB intermediate lens 102 can be removed to reduce the total light energy entering the ADB projection module in the first step, thereby reducing the light intensity of the converging ghost image. The outer surface of the ADB intermediate lens 102 is coated with an anti-reflective coating to ensure the total light energy utilization rate of the system.

[0162] For example, the antireflective film comprises at least two layers, wherein the refractive index of the layer in contact with air is lower than that of the other layers.

[0163] For example, the ADB outer lens 101 and / or the ADB intermediate lens 102 can be ellipsoidal lenses. The ellipsoidal shape helps to focus and reflect light, ensuring good illumination at both long and short distances. The ADB outer lens 101 and / or the ADB intermediate lens 102 can be made of high Abbe coefficient materials, such as K9 optical glass. PC (Polycarbonate) and PMMA (Polymethyl Methacrylate) materials can also be used.

[0164] In one optional embodiment, the ADB imaging module 2 includes an ADB inner lens, an ADB inner lens holder, an ADB printed circuit board assembly (PCBA), and an ADB heat sink. The ADB printed circuit board assembly is fixed to the ADB heat sink to form a first assembly; the ADB inner lens is fixed to the ADB inner lens holder to form a second assembly; the first assembly and the second assembly are fixedly connected to form the ADB imaging module.

[0165] The ADB printed circuit board assembly is equipped with an ADB light source, which can be an LED (Light Emitting Diode) light source. The LED is fixed on the corresponding ADB printed circuit board assembly by surface mount technology. The ADB printed circuit board assembly is equipped with an ADB heat sink, thereby enabling passive heat dissipation through heat conduction.

[0166] Figure 4A is a schematic diagram of a first assembly according to an embodiment of this application.

[0167] As shown in Figure 4A, the first assembly includes an ADB printed circuit board assembly 201 and an ADB heat sink 202, wherein the ADB printed circuit board assembly 201 is fixed to the ADB heat sink 202.

[0168] Figure 5A is a schematic diagram of an ADB image module according to an embodiment of this application.

[0169] As shown in Figure 5A, the ADB imaging module includes an ADB inner lens 203, an ADB inner lens support 204, an ADB printed circuit board assembly 201, and an ADB heat sink 202.

[0170] For example, the ADB inner lens 203 can be made of silicone, thereby improving the heat dissipation of the entire system and providing more flexible light source selection. Of course, other optical materials with high Abbe coefficients can also achieve the same function, such as materials with Abbe coefficients of 50 to 60.

[0171] For example, the inner surface of the ADB inner lens 203 can be connected to light guide teeth (which can be silicone light guide teeth). The inner surface of the ADB inner lens refers to its incident surface. The light is converged and modulated by the light guide teeth before being transmitted to the subsequent ADB projection module. Through total internal reflection within the light guide teeth, the large-angle light emitted by the ADB light source is coupled into the ADB inner lens 203 with a small divergence angle, serving as the object surface in the ADB projection module. This object surface is then projected to infinity on the image side through at least two glass lenses (such as the ADB outer lens and the ADB intermediate lens), producing an illumination effect that functions as the high beam of a car. 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.

[0172] For example, large-angle light rays not received by the light guide teeth on the ADB inner lens 203 can cause light leakage. Therefore, a perforated baffle matching the light guide teeth can be installed around the light guide teeth to block and avoid this. The perforated baffle 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, a horizontal dimension of 40–100 mm (47 mm recommended) and a vertical dimension of 5–50 mm (9.2 mm recommended) are acceptable. The recommended equivalent optical size is 47 mm * 6 mm.

[0173] For example, the ADB inner lens bracket 204 is connected to the ADB light-blocking plate, and the distance between the ADB inner lens 203 and the ADB light source is greater than the distance between the ADB light-blocking plate and the ADB light source. The ADB light-blocking plate is located near the light-incident surface of the ADB inner lens 203 (closer to the ADB light source side) and can be directly facing the edge light-emitting area of ​​the ADB light source. It can block stray light emitted by the ADB light source that has not been shaped by the light guide teeth or the ADB inner lens 203, preventing it from entering the ADB projection module, thereby achieving the effects of blocking stray light, constraining the light shape boundary, and avoiding glare.

[0174] For example, the headlight module may further include a fan and an air guide. The fan and the air guide are located at the rear end of the headlight module. The fan and the air guide are arranged at an angle relative to the ADB imaging module, forming a certain tilt angle with the ADB imaging module, that is, the fan and the air guide form a certain tilt angle with the vertical direction. The active cooling device formed by the tilted fan and the air guide can realize the convection exchange of heat between the ADB heat sink and the air, carrying away the heat from the ADB heat sink, thus achieving the effect of cooling the LED light source and other electronic components on the ADB printed circuit board assembly.

[0175] For example, the ADB radiator 202 is provided with fins, and the fins on the ADB radiator 202 are arranged at an angle. This method can increase the heat dissipation area, and the angled fins match the airflow direction of the angled fan, which can reduce wind resistance and improve convection efficiency.

[0176] Figure 6A is a schematic diagram of another vehicle light module according to an embodiment of this application.

[0177] As shown in Figure 6A, the components of the headlight module are as follows:

[0178] The vehicle headlight module includes an ADB outer lens 101, an ADB outer lens retainer 104, a baffle 105, an ADB intermediate lens 102, an ADB intermediate lens bracket 106, and a lens bracket 103. These components together form an ADB projection module.

[0179] The ADB outer lens 101 and the ADB intermediate lens 102 are respectively fixed to the lens bracket 103. The ADB outer lens retaining ring 104 is used to firmly fix the ADB outer lens 101 to the lens bracket 103. The baffle 105 is used to block stray light generated in the ADB imaging module, preventing this stray light from entering the ADB projection module (ADB outer lens part), thereby avoiding stray light from interfering with the final high beam shape. It can also constrain the propagation path of light to a certain extent, guiding the light to propagate in a predetermined direction. The ADB intermediate lens bracket 106 is used to support and accurately position the ADB intermediate lens 102, ensuring that the ADB intermediate lens 102 is accurately positioned in the headlight module.

[0180] The headlight module also includes an ADB inner lens 203, an ADB inner lens bracket 204, an ADB light-blocking plate 205 (specifically, a baffle), an ADB printed circuit board assembly 201, and an ADB heat sink 202. All these components together form an ADB image module.

[0181] The ADB printed circuit board assembly 201 is fixed to the ADB heat sink 202 to form a first assembly; the ADB inner lens 203 is fixed to the ADB inner lens bracket 204 to form a second assembly; the first assembly and the second assembly are fixedly connected to form the ADB imaging module. The ADB inner lens bracket 204 is connected to the ADB light-blocking plate 205, and the distance between the ADB inner lens 203 and the ADB light source is greater than the distance between the ADB light-blocking plate 205 and the ADB light source.

[0182] The headlight module also includes a fine-tuning bracket 3, an X-axis locking component 4, and Y-axis and Z-axis locking components 5. The ADB projection module is connected to the fine-tuning bracket 3 via the X-axis locking component 4. The ADB image module 2 is connected to the fine-tuning bracket 3 via the Y-axis and Z-axis locking components 5.

[0183] In the dimming process on the production line, the system can be divided into an ADB projection module and an ADB image module. The two are connected together by a fine-tuning bracket and screws, which can realize dimming in the X, Y and Z directions.

[0184] The functions of the headlight module can be further adjusted by adjusting the surface shape (spherical, second-order aspherical, high-order aspherical, etc.), thickness (5-45mm), spacing (3-80mm), inner lens surface shape (spherical, second-order aspherical, high-order aspherical, etc., with concentric curved surfaces recommended for the front and rear surfaces), thickness (1-10mm, with 2-5mm recommended), and the surface shape (planar, curved) of the five surfaces of the light guide teeth.

[0185] For example, the fan may be an axial fan or a turbo fan, etc.

[0186] Figure 1B is a schematic diagram of another vehicle light module according to an embodiment of this application.

[0187] As shown in Figure 1B, the vehicle headlight module may include an ADB outer lens 2 and an ADB intermediate lens 19. The light from the ADB light source passes sequentially through the ADB intermediate lens 19 and the ADB outer lens 2 before being emitted. The ADB outer lens 2 and / or the ADB intermediate lens 19 are coated with an anti-reflective coating.

[0188] The light from the ADB light source is projected externally using a projection lens assembly to achieve the ADB light pattern. The projection lens assembly includes two plano-convex glass lenses: the ADB outer lens 2 and the ADB intermediate lens 19. During this optical path, reflections at the interface between different media result in significant energy loss for the system. Therefore, the ADB outer lens 2 and / or the ADB intermediate lens 19 in the projection lens assembly are coated with an anti-reflection film to reduce the component of reflected light at the interface and increase the system's light energy utilization rate.

[0189] The ADB outer lens 2 includes an outer surface 201 and an inner surface 202. The outer surface 201 of the ADB outer lens refers to the light-emitting surface of the ADB outer lens 2, and the inner surface 202 of the ADB outer lens refers to the light-incident surface of the ADB outer lens 2.

[0190] For example, both the outer surface 201 and the inner surface 202 of the ADB outer lens are coated with an anti-reflection film, thereby reducing reflection loss to a greater extent.

[0191] For example, the outer surface 201 of the ADB outer lens is provided with a pattern to achieve a uniform light pattern. In this case, the outer surface 201 of the ADB outer lens is uncoated, and the inner surface 202 of the ADB outer lens is coated with an anti-reflective film.

[0192] The ADB intermediate lens 19 includes an outer surface 1901 and an inner surface 1902. The outer surface 1901 of the ADB intermediate lens refers to the light-emitting surface of the ADB intermediate lens 19, and the inner surface 1902 of the ADB intermediate lens refers to the light-incident surface of the ADB intermediate lens 19.

[0193] For example, both the outer surface 1901 and the inner surface 1902 of the ADB intermediate lens are coated with an anti-reflection film, thereby reducing reflection loss to a greater extent.

[0194] For example, the outer surface curvature of the ADB inner lens is relatively small, which easily leads to multiple reflections with the flat inner surface of the ADB intermediate lens before being projected through the projection lens group, resulting in a "ghosting" defect. This causes the dark areas where the adaptive high beam is turned off to still be illuminated by the "ghosting" of the un-turned pixels, causing glare and compromising driving safety. In addition to the flat inner surface of the ADB intermediate lens, the reflection of the curved outer surface of the ADB intermediate lens acts like a concave mirror for light incident from behind, resulting in a converging effect. The converged reflected light is then reflected again by the outer surface of the ADB inner lens and exits through the projection lens group, forming a converged "ghosting" with a stronger light intensity than the "ghosting" formed by the inner surface of the ADB intermediate lens, leading to greater road safety hazards. Therefore, the anti-reflection coating on the inner surface of the ADB intermediate lens can be removed to reduce the total light energy entering the projection lens group in the first step, thereby reducing the intensity of the converged "ghosting." The outer surface of the ADB intermediate lens is coated with an anti-reflection coating to ensure the overall light energy utilization rate of the system.

[0195] The ADB optical system operates in the visible light band. The reflection and refraction of light in a medium can be described by Fresnel's formula for the redistribution of the light field.

[0196] Figure 2B is a schematic diagram of a light reflection and refraction process according to an embodiment of this application.

[0197] When light is incident perpendicularly at the interface between the air and the antireflective coating, the reflectances at the two interfaces of the thin film are as follows:

[0198] Where r1 represents the reflection coefficient at the interface between air and the antireflection coating, r2 represents the reflection coefficient at the interface between the antireflection coating and the substrate (such as a lens), n0 represents the refractive index of air, n1 represents the refractive index of the antireflection coating, and n2 represents the refractive index of the substrate (such as a lens).

[0199] If we liken the antireflection coating to a parallel plate, the composite amplitude A of its reflected light field is... r for:

[0200] Where δ is the phase difference between the two reflected beams in the antireflection coating, θ is the angle of refraction of the light in the antireflection coating medium, h is the thickness of the antireflection coating, λ is the wavelength of the light, and i is the imaginary unit.

[0201] The composite reflection coefficient r is:

[0202] If the phase difference δ between the two reflected beams is π, then the total reflection coefficient of the reflected beam is r = |r1 - r2|. At this point, the reflected beam component is at its minimum, and the transmitted beam component is at its maximum. The optical path difference is n1h = λ0 / 4, where λ0 represents the target wavelength of the antireflection coating system. Furthermore, when the refractive index of the antireflection coating... When the reflectivity is 0, all light of that wavelength is transmitted. However, for a typical case of light entering the lens from air, n0 = 1, n2 = 1.5, and n1 ≈ 1.22 calculated from the above formula. But currently, there is no coating material with such a low refractive index. The transmitted light component can be increased by using double or multilayer coatings.

[0203] The double-layer antireflective coating has a refractive index of n g A thin film with a thickness of λ0 / 4 and a refractive index of n2 is deposited on a substrate. Then, for wavelength λ0, the equivalent refractive index of the combined thin film and substrate system becomes N = n2. 2 / n g . When n2>n g When N > n g In other words, after depositing a high-refractive-index film layer with a thickness of λ0 / 4 on the substrate, the refractive index of the substrate changes from n... g Increasing the refractive index (N) to λ0 / 4 and then depositing a low-refractive-index film can achieve a better antireflection effect, increasing transmittance compared to a single-layer antireflection film. However, this approach has a narrower wavelength bandwidth, with a rapid increase in reflectance in the wavelength ranges around λ0. The wavelength-reflectance curve is shaped like a "v", making it suitable for narrow-band applications. Alternatively, a coating scheme with n1h1 = λ0 / 4 and n2h2 = λ0 / 2 can be used. In this scheme, the wavelength-reflectance curve is shaped like a "w", and the film system has a good antireflection effect over a wider wavelength range, making it suitable for applications with a broad spectrum.

[0204] The principle of multilayer antireflective coatings is the same as that of double-layer antireflective coatings. The reflection coefficient is calculated starting from the layer adjacent to the substrate, and then recursively calculated up to the first layer adjacent to air to obtain the total reflectivity of the film system. Adjusting the thickness and refractive index of different layers can change the bandwidth and transmittance of the antireflective coating system. Multilayer films can be improved forms of the aforementioned "V-shaped film" and "W-shaped film".

[0205] For example, the antireflective film comprises at least two layers, wherein the refractive index of the layer in contact with air is lower than that of the other layers.

[0206] For example, the antireflective coating can be a double-layer film as shown in Table 1 below. In this film, film 1 is in contact with the lens, and film 2 is in contact with the air. The low-refractive-index film (film 2) can be made of magnesium fluoride, and the high-refractive-index film (film 1) can be made of zinc sulfide.

[0207] Table 1. Coefficient of Double-Layer Antireflection Coating

[0208] For example, the antireflective coating can be a three-layer coating as shown in Table 2 below. Among them, film 1 is in contact with the lens, film 2 is located between film 1 and film 3, film 3 is in contact with air, the low refractive index film layer (film 3) material can be magnesium fluoride, the high refractive index film layer (film 2) material can be zirconium sulfide, and the high refractive index film layer (film 1) material can be zinc sulfide.

[0210] Figure 3B is a structural schematic diagram of another vehicle light module according to an embodiment of this application.

[0211] As shown in Figure 3B, the vehicle headlight module may include: an ADB outer lens 2, an ADB intermediate lens 19, and an ADB inner lens 10. The light from the ADB light source passes through the ADB inner lens 10, the ADB intermediate lens 19, and the ADB outer lens 2 in sequence before being emitted.

[0212] The ADB inner lens 10 includes an outer surface 1001 and an inner surface 1002. The outer surface 1001 of the ADB inner lens refers to the light-emitting surface of the ADB inner lens 10, and the inner surface 1002 of the ADB inner lens refers to the light-incident surface of the ADB inner lens 10.

[0213] For example, to reduce ghost stray light, the non-light-emitting area on the outer surface 1001 of the ADB inner lens is a rough surface. By setting the surface of the non-light-emitting area to a rough surface, the reflectivity can be reduced. Here, the non-light-emitting area refers to the area where no light is emitted from the two ends of the outer surface 1001 of the ADB inner lens.

[0214] For example, the inner surface 1002 of the ADB inner lens is connected to the light guide teeth (which can be silicone light guide teeth), and the light is focused and modulated by the light guide teeth and then transmitted to the subsequent glass projection lens system.

[0215] In this embodiment, by redefining the optical coating positions and parameters of the two plano-convex lenses in the ADB lens group, the light transmittance / reflection ratio of the lens group is increased, the optical utilization rate is improved, and ghosting aberration is reduced. This reduces stray light in dark areas, lowers the risk of glare, and ensures the driving safety of the vehicle, oncoming vehicles, and following drivers.

[0216] Figure 1C is a schematic diagram of the structure of a heat sink according to an embodiment of this application.

[0217] As shown in Figure 1C, the heat sink includes a high beam / low beam heat sink 14 and an ADB heat sink 15, wherein the high beam / low beam heat sink 14 and the ADB heat sink 15 have a heat transfer end and a heat dissipation end, respectively.

[0218] 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.

[0219] The heat transfer end of the ADB heat sink 15 is used to contact the ADB printed circuit board assembly.

[0220] 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.

[0221] 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.

[0222] 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.

[0223] 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.

[0224] Figure 2C 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 in Figure 3C.

[0225] As shown in Figure 2C, the heat dissipation module may include: high beam PCBA12, ADB PCBA13, high beam heat sink 14, ADB heat sink 15, module bracket (not shown in Figure 2C), fan 17 and air guide shroud 18. The high beam heat sink 14 and the ADB heat sink 15 have heat transfer end and heat dissipation end, respectively.

[0226] 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.

[0227] The heat transfer end of the ADB heat sink 15 is used to contact the ADB printed circuit board assembly 13.

[0228] 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.

[0229] 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.

[0230] 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.

[0231] 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.

[0232] 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.

[0233] 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.

[0234] Figure 4C is a schematic diagram of a heat sink fin according to an embodiment of this application. The fins of the high beam / low beam heat sink 14 and / or the fins of the ADB heat sink 15 can both have the structure shown in Figure 4C.

[0235] As shown in Figure 4C, 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.

[0236] Figure 5C is a schematic diagram of another heat sink fin according to an embodiment of this application. The fins of the high beam / low beam heat sink 14 and / or the fins of the ADB heat sink 15 can both have the structure shown in Figure 5C.

[0237] As shown in Figure 5C, the fins 25 of the high and 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.

[0238] 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.

[0239] 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.

[0240] 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.

[0241] 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.

[0242] Optionally, the air guide shroud 18 can be made of PBT (polybutylene terephthalate), which is heat-resistant, flame-retardant, lightweight, and low-cost.

[0243] 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.

[0244] 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.
