Description

Technical Field

[0001] This utility model relates to the field of vehicle lighting technology, and in particular to a vehicle lighting assembly and a vehicle. Background Technology

[0002] With the widespread application of pixel headlights and the increasing demand for lighting, the phenomenon of using some pixels of pixel headlights as cutoff lines to form dynamic cornering lighting is becoming more and more common. The cutoff line function can improve the driver's visibility and safety when driving on curves. However, the overlap of the cutoff line and the horizontal widening of the light can easily create a light-dark dividing line, affecting the driver's subjective perception. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of this invention is to provide a vehicle headlight assembly. According to this invention, the vehicle headlight assembly, by setting a light-diffusing element in the low-light zone of the optical components, can effectively weaken the bright-dark boundary line formed by the low-light cutoff line, making the light distribution emitted by the headlight assembly more reasonable and uniform, providing the driver with a more comfortable visual experience, reducing eye fatigue, and improving the subjective comfort and enjoyment of driving.

[0004] This utility model also proposes a vehicle including the above-mentioned headlight assembly.

[0005] The vehicle headlight assembly according to this utility model includes: a housing, an optical component, and a light source. A limiting part is provided on the housing. The optical component is disposed on the housing and cooperates with the limiting part to restrict the movement of the optical component relative to the housing. A light-inlet surface is formed on one side of the optical component, and a light-outlet surface is formed on the other side of the optical component. The light source is disposed on one side of the light-inlet surface of the optical component and emits light toward the optical component. The optical component forms a low beam area and a high beam area on the light-outlet surface, respectively. The light rays in the low beam area form a cutoff line. The cutoff line and the horizontal broadening of the light rays superimpose to form a bright-dark boundary line. A light-uniforming component for weakening the bright-dark boundary line is provided in the low beam area.

[0006] The vehicle headlight assembly according to this utility model has a housing that is connected to the vehicle body. A limiting part is provided on the housing. Optical components (such as lenses) can be assembled on the housing. During processing, a limiting structure that cooperates with the limiting part can be provided on the optical components to improve the stability of the assembly between the optical components and the housing. A light-inlet surface and a light-outlet surface are formed on the optical components. A light source is set on the light-inlet surface of the optical components and emits light towards the light-inlet surface. A low beam area and a high beam area are formed on the light-outlet surface of the optical components. The low beam area can refract the light emitted by the light source to form the low beam of the vehicle headlight, and the high beam area can refract the light emitted by the light source to form the high beam of the vehicle headlight. While existing pixel headlights can create a dynamic cutoff line through some pixels that shifts with the curve angle during vehicle cornering, thus widening the driver's field of vision to some extent, the overlap of the cutoff line with the horizontal widening creates a light-dark boundary on the ground, affecting the driver's subjective perception. The headlight assembly of this invention, however, incorporates a light-dark equalizer in the low beam area, effectively weakening this light-dark boundary. This allows the driver to obtain a more uniform and clear illumination field of vision when cornering, reducing visual interference and blind spots caused by the light-dark boundary, enabling more accurate observation of road conditions, early detection of potential hazards, and improved safety when cornering. Ultimately, this enhances the driver's subjective comfort and enjoyment.

[0010] According to one embodiment of the present invention, the surface of the light-diffusing component is formed with a textured surface.

[0011] According to one embodiment of the present invention, the light-diffusing element further includes: a light-diffusing sheet, the light-diffusing sheet being spaced apart on the light-emitting surface of the optical element, and the light-diffusing sheet being disposed opposite to at least a portion of the near-light region.

[0016] The vehicle according to this utility model includes the headlight assembly in the above embodiments. Since the vehicle according to this utility model is equipped with the headlight assembly in the above embodiments, the headlight assembly can effectively weaken the bright and dark boundary line formed by the low beam cutoff line by setting a light-diffusing element in the low beam area of ​​the optical element, making the light distribution emitted by the headlight assembly more reasonable and uniform, which can bring a more comfortable visual experience to the driver, reduce eye fatigue, and improve the subjective comfort and pleasure of driving.

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0028] With the widespread application of pixel headlights and the increasing demand for lighting, the phenomenon of using some pixels of pixel headlights as cutoff lines to form dynamic cornering lighting is becoming more and more common. The cutoff line function can improve the driver's visibility and safety when driving on curves. However, the overlap of the cutoff line and the horizontal widening of the light can easily create a light-dark dividing line, affecting the driver's subjective perception.

[0029] The following is for reference. Figures 1-2 Description of a vehicle lighting assembly according to an embodiment of the present utility model.

[0030] The vehicle lamp assembly 1 according to this utility model includes: a housing 11, an optical element 12, and a light source 13. A limiting part 111 is provided on the housing 11. The optical element 12 is disposed on the housing 11 and cooperates with the limiting part 111 to restrict the movement of the optical element 12 relative to the housing 11. A light-inlet surface is formed on one side of the optical element 12, and a light-outlet surface is formed on the other side of the optical element 12. The light source 13 is disposed on one side of the light-inlet surface of the optical element 12 and emits light toward the optical element 12. The optical element 12 forms a low beam area and a high beam area on the light-outlet surface. The light in the low beam area forms a cutoff line. The cutoff line and the horizontal broadening of the light form a bright-dark boundary line. A light-dampening element 14 for weakening the bright-dark boundary line is provided in the low beam area.

[0031] According to the present invention, the vehicle lamp assembly 1 is provided with a housing 11, which is connected to the vehicle body. A limiting part 111 is provided on the housing 11. An optical component 12 (e.g., a lens) can be assembled on the housing 11. During processing, a limiting structure that cooperates with the limiting part 111 can be provided on the optical component 12 to improve the stability of the assembly between the optical component 12 and the housing 11. A light-inlet surface and a light-outlet surface are formed on the optical component 12. A light source 13 is provided on the light-inlet surface of the optical component 12 and emits light towards the light-inlet surface. A low beam area and a high beam area are formed on the light-outlet surface of the optical component 12. The low beam area can refract the light emitted by the light source 13 to form the low beam of the vehicle lamp, and the high beam area can refract the light emitted by the light source 13 to form the high beam of the vehicle lamp. While existing pixel headlights can create a dynamic cutoff line through some pixels and shift with the curve angle during vehicle turning, thus widening the driver's field of vision to some extent, the cutoff line, when superimposed with the horizontal widening, creates a light-dark boundary line on the ground, which can affect the driver's subjective perception. However, the headlight assembly 1 of this invention has a light-dark equalizer 14 in the low beam area, which can effectively weaken this light-dark boundary line. As a result, the driver can obtain a more uniform and clear illumination field of vision when driving on curves, reducing visual interference and blind spots caused by the light-dark boundary line, thereby more accurately observing road conditions, detecting potential dangers in advance, and significantly improving the safety of driving on curves.

[0032] Because the headlight assembly 1 incorporates a light-diffusing element 14 in the low beam zone, it weakens the boundary between bright and dark areas, resulting in a more reasonable and uniform distribution of light emitted by the headlight assembly 1. This ensures sufficient illumination for its own lane while preventing excessively concentrated or improperly distributed light from illuminating oncoming lanes. This effectively prevents glare for drivers in oncoming lanes due to strong light, reducing the risk of traffic accidents and ensuring their safety. The light-diffusing element 14 alters the light propagation characteristics, making the light softer and more uniform. Compared to light with a clear boundary between bright and dark areas, this softer and more uniform light provides a more comfortable visual experience for the driver, reducing eye fatigue. Drivers will not experience discomfort due to headlight illumination issues during long drives, thus improving subjective comfort and driving pleasure.

[0033] In addition, the optical component 12 cooperates with the limiting part 111 to ensure the stability of the optical component 12 during vehicle operation, and avoid the optical component 12 from shifting due to factors such as vehicle bumps and vibrations, thereby ensuring that the optical performance of the headlight assembly 1 is always in the best state, so that the light equalizer 14 can continuously and effectively play the role of weakening the bright and dark dividing line.

[0034] In some embodiments, the limiting part 111 can be configured as a snap-fit ​​protrusion, and a slot can be provided on the optical component 12. The snap-fit ​​cooperation between the slot and the snap-fit ​​protrusion can improve the stability of the assembly of the optical component 12.

[0035] According to one embodiment of this utility model, the light-diffusing element 14 is constructed as a protrusion or groove disposed in the near-light zone. The structure of the protrusion or groove can break the linear propagation law of light in the near-light zone. When light shines on the surface of these protrusions or grooves, reflection and refraction occur, causing the originally concentrated light to scatter in different directions. This scattering effect makes the distribution of light in the near-light zone more uniform, thereby effectively weakening the light-dark boundary formed by the overlap of the cutoff line and the horizontal broadening of the light, making the ground lighting softer and more natural, and reducing visual discomfort to drivers caused by excessive differences in brightness. Moreover, through the scattering of light by the protrusion or groove, the light can cover a wider area. Compared to the case without this structure, the light is no longer limited to a specific direction and range, but can more fully fill every corner of the near-light zone, further blurring the light-dark boundary, improving the overall lighting effect, and providing drivers with a clearer road view.

[0036] The light scattering caused by protrusions or grooves reduces the intensity difference of light at different locations within the low beam area. Areas that might otherwise be locally bright become less so due to light scattering, while lower-brightness areas receive some light supplementation. This results in a more uniform light intensity across the entire low beam area, reducing contrast and making the road lighting softer for the driver, thus reducing eye fatigue. During vehicle operation, strong glare can severely interfere with the driver's vision, affecting driving safety. The light scattering effect of protrusions or grooves effectively prevents light from concentrating too much in the driver's eyes, reducing the likelihood of glare. Even at night or under complex lighting conditions, the driver can maintain clear vision, improving driving comfort and safety.

[0037] Furthermore, constructing the light-diffusing element 14 as a protrusion or groove is relatively simple and easy to implement during the design and manufacturing process of the optical element 12. It does not require complex processes or additional materials, reducing production costs and manufacturing difficulty, while also improving production efficiency and product quality consistency. Moreover, by changing parameters such as the shape, size, and spacing of the protrusions or grooves, the light scattering effect and distribution can be flexibly adjusted, allowing the headlight assembly 1 to be optimized according to different usage scenarios and needs. For example, the lighting effect of the low beam zone can be adjusted for different vehicle models, road conditions, or driving habits to provide the best driving visual experience.

[0038] According to one embodiment of this utility model, the light-diffusing element 14 forms multiple spaced stripe textures 141 in the near-light zone. The stripe textures 141 have specific shapes and orientations, enabling directional scattering of light. Compared to ordinary protrusions or grooves in the above embodiments, the stripe textures 141 can more precisely control the direction of light scattering, allowing light to diffuse according to a predetermined angle and range. For example, by rationally designing the tilt angle of the stripe textures 141, light can be scattered in a targeted manner in the horizontal or vertical direction, thereby better filling the bright and dark areas formed by the overlap of the cutoff line and horizontal widening in the near-light zone, further weakening the light-dark boundary line, and making the ground lighting more uniform. The multiple spaced stripe textures 141 form a complex optical structure. Light undergoes multiple reflections and refractions when passing through these textures. This multiple optical effect allows light to form a multi-layered distribution in the near-light zone. The light from different layers overlaps and complements each other, further improving the uniformity of light distribution. Compared to single-layer scattering, multi-layered distribution can more effectively eliminate differences in brightness and darkness, providing the driver with a clearer and more comfortable visual environment.

[0039] According to one embodiment of the present invention, striped textures 141 are spaced apart in the height directions of the optical element 12 and extend in the width direction of the near-light zone. The spaced striped textures 141 in the height directions of the optical element 12 allow light to be scattered and redistributed multiple times in the vertical direction. When light is emitted from the light source 13 and passes through these striped textures 141, textures at different heights will scatter the light to different degrees, thereby eliminating the problem of uneven brightness that may exist in the vertical direction. For example, areas that might have excessively high or low brightness at the top or bottom of the headlight assembly 1 can be made more uniformly distributed in the vertical direction by these spaced striped textures 141, reducing the difference in brightness in the vertical direction and providing the driver with a clearer and more consistent vertical field of vision.

[0040] During vehicle operation, objects of varying heights, such as pedestrians, traffic signs, and obstacles, exist on the road. This striped pattern 141, spaced apart in the vertical direction and extending in the width direction, allows for wider and more efficient distribution of light in the vertical direction. For lower-height objects, such as potholes or small obstacles, the light can fully illuminate their surfaces, allowing the driver to spot them promptly. For higher-height objects, such as traffic lights or roadside billboards, sufficient light ensures clear visibility, improving the vehicle headlights' adaptability to objects of different heights.

[0041] The striped texture 141 extends in the width direction of the near-light zone, guiding light to spread more widely in the horizontal direction. The texture extending in the width direction also creates a lateral scattering effect, allowing the light to cover a wider road area and providing more sufficient illumination in the horizontal direction. This reduces blind spots on both sides of the road, enabling drivers to spot roadside situations, such as suddenly appearing pedestrians or vehicles, earlier, thus improving driving safety. Furthermore, multiple striped textures 141 spaced apart in the height direction and extending in the width direction work together to form a continuous lighting band in the horizontal direction, avoiding gaps or areas of excessive brightness or darkness, resulting in a smoother and more natural road lighting for the driver. At night or under complex lighting conditions, continuous horizontal lighting provides the driver with a more stable visual reference, helping to maintain the vehicle's direction of travel and judge road direction.

[0042] According to one embodiment of the present invention, the surface of the light-diffusing element 14 is formed with a textured surface. The texture has a complex and irregular microscopic surface structure. When light shines on the textured surface of the light-diffusing element 14, reflection and refraction occur at various tiny undulations in the texture. Compared to a smooth surface, this irregular structure allows light to scatter at more different angles, rather than concentrating in a few specific directions. This makes the light distribution in the near-light zone more uniform, effectively weakening the light cutoff line and the horizontal broadening of the light beam to form a bright-dark boundary, making ground lighting softer and more natural, and reducing visual discomfort for drivers caused by excessively bright or dark areas. The microscopic texture of the texture increases the contact area and interaction opportunities between light and the surface of the light-diffusing element 14. When light passes through the textured surface, scattering occurs over a wider area, thereby expanding the scattering range of light. Compared to a light-diffusing element 14 without a texture, the textured light-diffusing element 14 can more fully disperse light to all corners of the near-light zone, further improving the uniformity of light distribution and enhancing the overall lighting effect.

[0043] By scattering light at multiple angles and expanding the scattering range through the textured surface, the difference in light intensity at different locations within the low beam area is reduced. Areas that might otherwise have high brightness are dimmed due to light scattering, while low-brightness areas receive some light supplementation, resulting in a more uniform light intensity across the entire low beam area. This reduces the contrast of light intensity, providing the driver with a more comfortable visual environment and reducing eye fatigue caused by frequent adjustments in areas of alternating light and dark. This is especially beneficial during long nighttime driving, effectively improving driving comfort and safety. During vehicle operation, strong glare can severely interfere with the driver's vision and affect driving safety. The textured surface diffuses light, preventing it from being concentrated too much in the driver's eyes, thus reducing the likelihood of glare. Even when there are oncoming vehicles or other strong light sources, the headlights with textured light-diffusing elements can reduce the impact of reflected glare on the driver, allowing them to maintain clear vision and more accurately observe road conditions.

[0044] According to one embodiment of the present invention, the light-diffusing element 14 further includes a light-diffusing plate 142, which is spaced apart on the light-emitting surface of the optical element 12 and faces at least a portion of the near-light area. The light-diffusing plates 142, spaced apart on the light-emitting surface of the optical element 12 and facing a portion of the near-light area, can perform secondary adjustment on the light after the initial processing by the optical element 12. In the near-light area, there may be some areas with uneven light distribution, such as bright spots or dark areas caused by the structure of the optical element 12 itself or the characteristics of the light source 13. The light-diffusing plates 142 can scatter and redistribute these local light rays, making the light more evenly distributed in these areas, further weakening the difference between bright and dark areas, improving the light uniformity of the entire near-light area, and providing the driver with a clearer and more comfortable visual environment. The light-diffusing plates 142, facing at least a portion of the near-light area, can guide and expand the direction of light propagation to a certain extent, allowing the light to scatter to a wider area, thereby expanding the effective illumination range of the vehicle headlight. During vehicle operation, especially when turning or in complex road conditions, the expanded lighting range allows drivers to detect potential hazards on the road in advance, such as pedestrians and obstacles, thereby improving driving safety.

[0045] In addition, the edge of the low beam zone is often a region with weak light distribution, which is prone to blind spots. The setting of the light diffuser 142 can also enhance and optimize the light in the edge area. Through the scattering effect, more light can reach the edge area, improving the brightness and quality of the edge area lighting. This allows drivers to have a clearer field of vision when observing the sides of the road and turning, reducing the risk of accidents caused by insufficient edge lighting.

[0046] In some embodiments, the light-diffusing plate 142 can be selected according to actual needs. For example, when there is a high demand for weakening the light-dark boundary line, the light-diffusing plate 142 can be set.

[0047] According to one embodiment of this utility model, the light-diffusing element 14 is constructed of plastic. Plastic materials exhibit good dimensional stability and optical performance stability within a certain temperature and humidity range. During vehicle operation, the headlights are affected by factors such as changes in ambient temperature and vibration. The plastic light-diffusing element 14 can maintain a relatively stable shape and optical characteristics under these conditions, and is not prone to deformation or attenuation of optical performance. This ensures that the headlights provide a stable and good lighting effect over a long period, reducing problems such as abnormal light distribution caused by changes in material properties.

[0048] Plastics have excellent plasticity, enabling the manufacture of light-diffusing components 14 with various complex shapes through molding processes such as injection molding and compression molding. For example, light-diffusing components 14 with specific curvatures, concave and convex structures, or textures can be designed. These complex structures can precisely control the scattering, refraction, and reflection of light. Compared to some traditional materials, plastics can more flexibly optimize light distribution, making the light in the low beam area more uniform, reducing differences in brightness and darkness, improving lighting quality, and providing drivers with a clearer and more comfortable field of vision.

[0049] Furthermore, plastic is a relatively inexpensive material with low raw material costs. Moreover, plastic molding technology is mature, production efficiency is high, and large-scale automated production is possible. Compared to materials such as glass, using plastic to manufacture the light-diffusing component 14 can significantly reduce the manufacturing cost of the vehicle lamp assembly 1, which is beneficial for the large-scale production and widespread application of the vehicle lamp assembly 1. It can also reduce the overall cost of the vehicle and improve the product's market competitiveness.

[0050] According to one embodiment of this utility model, the light-diffusing element 14 is constructed of plexiglass. Plexiglass has extremely high light transmittance, typically exceeding 92%. When light passes through the plexiglass serving as the light-diffusing element 14, only a very small portion of the light is absorbed or reflected, while most of the light can pass through smoothly and reach the illumination area. Compared to some ordinary plastics, plexiglass can transmit the light emitted by the light source 13 more efficiently, providing the low beam area of ​​the headlights with sufficient brightness and offering the driver a clear and bright field of vision. This is especially beneficial at night or in low-light conditions, effectively improving driving safety. Furthermore, plexiglass can achieve uniform light scattering through specific processing techniques, such as forming tiny textures on its surface or adding scattering particles internally. This allows for a more even distribution of light in the low beam area, avoiding areas that are too bright or too dark. It effectively weakens the boundary between light and dark formed by the cutoff line and the horizontal expansion of the light beam, making ground lighting softer and more natural, and reducing eye fatigue caused by uneven light.

[0051] In addition, acrylic glass has high strength and good impact resistance. During vehicle operation, headlights may be subjected to impacts from flying stones, collisions, and other external forces. Compared with some ordinary glass or brittle plastics, acrylic glass light-diffusing components 14 can better withstand these impacts and are less prone to breakage or damage. This protects the optical components and light source 13 inside the headlight, extends the lifespan of the headlight, and reduces maintenance costs and safety hazards caused by headlight damage.

[0052] In some embodiments, the acrylic glass may be made of PMMA-DF23.

[0053] According to one embodiment of this utility model, the light-diffusing element 14 is constructed of polycarbonate and has a textured surface. Polycarbonate itself has good optical properties, and the textured surface design further enhances its ability to scatter light. When light passes through the polycarbonate light-diffusing element 14, the texture causes multiple irregular scattering and reflections of the light, dispersing the concentrated light to a wider area, thereby effectively reducing the brightness difference in the low beam zone, making the light distribution more uniform, helping to eliminate bright spots and dark areas caused by concentrated light, and providing the driver with a clearer and more comfortable field of vision, especially at night or in low light conditions, significantly improving driving safety. The shape, depth, and distribution density of the texture can be precisely designed according to actual needs, thereby achieving effective control of the light propagation direction. By reasonably designing the texture parameters, light can be scattered at specific angles and ranges to meet the needs of different lighting areas of the vehicle headlight. For example, near the cutoff line of the low beam zone, the boundary of the light can be precisely controlled by adjusting the texture, making the cutoff line clearer and sharper, and avoiding upward scattering of light that causes glare interference to other vehicle drivers. The high light transmittance of polycarbonate combined with the scattering effect of the leather texture can maximize the utilization of light while ensuring uniform light distribution. Compared with traditional light-diffusing materials, this combination can reduce the absorption and reflection loss of light during propagation, allowing more light to reach the illuminated area, thereby achieving a brighter lighting effect with the same light source power, or reducing energy consumption without increasing the power of the light source.

[0054] Furthermore, during prolonged vehicle operation, the headlights generate heat. Polycarbonate possesses excellent heat resistance, maintaining stable physical and optical properties at high temperatures. It also exhibits good dimensional stability, resisting deformation under temperature changes and prolonged use, ensuring the shape and dimensions of the light-diffusing element 14 consistently meet design requirements, thus guaranteeing unaffected headlight illumination. Moreover, polycarbonate has a relatively low density and is lightweight. Using polycarbonate as the light-diffusing element 14 reduces the overall weight of the headlight assembly 1, contributing to a lower vehicle curb weight, improved fuel economy or driving range, and enhanced handling and stability. Additionally, the lighter light-diffusing element 14 facilitates easier and faster installation, increasing production efficiency.

[0055] The textured surface design also gives the headlights a unique appearance. During processing, the texture can present a variety of delicate and rich texture effects, making the headlights look more upscale and refined, improving the overall aesthetics of the vehicle and brand recognition. Different shapes and arrangements of the texture can also create different visual effects, meeting the personalized needs of different car models and user groups.

[0056] In some embodiments, the light-diffusing element 14 may be made of high-temperature resistant PC material.

Since the vehicle according to this utility model is equipped with the headlight assembly 1 in the above embodiments, the headlight assembly 1 can effectively weaken the bright and dark dividing line formed by the low beam cutoff line by setting the light-dark dividing line in the low beam area of ​​the optical element 12, so that the light distribution emitted by the headlight assembly 1 is more reasonable and uniform, which can bring a more comfortable visual experience to the driver, reduce eye fatigue, and improve the subjective comfort and pleasure of driving.
