Description

Technical Field

[0001] This utility model belongs to the field of vehicle lighting technology, and specifically relates to a lighting device and vehicle for motor vehicles. Background Technology

[0002] The purpose of motor vehicle lighting is to provide wide and uniform road lighting at night and in conditions of insufficient ambient light during the day, so as to ensure the safety of motor vehicle driving.

[0003] In recent years, the design trend of automotive headlights has increasingly leaned towards a slimmer and more slanted shape. Headlight design is a complex process that requires consideration of various factors to achieve optimal lighting performance and a unique appearance. However, while this design is sophisticated, it presents several technical challenges. For example, the limited size of the headlight's light-emitting aperture reduces the light output efficiency of the lighting unit. Furthermore, the slanted design of the imaging lens can cause severe coma and chromatic aberration, resulting in uneven light distribution and inconsistent light color between the left and right lighting units.

[0004] To address the aforementioned technical issues, the current mainstream approach is to reduce the imaging range of the lens to a level where aberrations are not severe. However, this method reduces the illumination width and does not completely resolve the problem of inconsistent light color between the left and right illumination units.

[0005] Therefore, how to overcome the above-mentioned technical defects is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0028] This utility model provides a lighting device for motor vehicles, the advantages of which are:

[0029] For lighting devices with a slender and angled light-emitting surface, two types of light-emitting modules were specifically designed: a first light-emitting module for generating a converging beam and a second light-emitting module for generating a diffused beam. On one hand, the first light-emitting module emits collimated light, reducing refracted light from the front and rear surfaces of the projection lens assembly, thereby correcting imaging defects caused by the angled design of the projection lens assembly. On the other hand, the second light-emitting module emits diffused light, thus not affecting the lighting width and avoiding problems such as uneven light distribution and inconsistent light color between the left and right lighting units.

[0030] By combining the optical effects of the first and second light-emitting modules, the problems of coma and color difference caused by the tilted shape can be solved, ensuring the uniformity and width of the illumination.

[0051] 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.

[0052] The core of this utility model is to provide a lighting device and vehicle for motor vehicles. For lighting devices with a slender and inclined light-emitting surface, it can solve the problems of coma and color difference caused by the inclined shape, and ensure the uniformity and width of the lighting.

[0053] To enable those skilled in the art to better understand the technical solutions provided by this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0054] For details, please refer to Figures 1-11 The present invention provides a lighting device for motor vehicles, comprising: at least one first light-emitting module for generating a converging light beam and at least one second light-emitting module for generating a diffused light beam.

[0055] Both the first and second light-emitting modules include a light source assembly 1 and a reflector bowl assembly 2. The first light-emitting module also includes a reflector assembly 3, a corrective lens assembly 4, and a light-emitting lens, while the second light-emitting module also includes a light-blocking sheet assembly 6 and a diffuser lens. All the light-emitting lenses and diffuser lenses are connected in sequence to form an inclined projection lens assembly 5. This projection lens assembly 5 is a one-piece structure, and its inclined and slender appearance is to cater to current aesthetic demands.

[0056] It should be understood that this application only describes in detail the structure of the light source assembly 1, the reflector bowl assembly 2, the reflector sheet assembly 3, the corrective lens assembly 4, the light-blocking sheet assembly 6, and the projection lens assembly 5. Other structures of the lighting device in this solution, such as the housing, PCB board, wiring harness, heat sink, etc., are not shown in the figures and will not be described further.

[0057] The first light-emitting module includes a light source assembly 1, a reflector assembly 2, a reflector sheet assembly 3, a corrective lens assembly 4, and a light-emitting lens. One light source assembly 1 corresponds to one reflector assembly 2, one reflector sheet assembly 3, one corrective lens assembly 4, and one light-emitting lens. The light emitted from the light source assembly 1 is reflected by the reflector assembly 2 and then sequentially passes through the reflector assembly 3, the corrective lens assembly 4, and the light-emitting lens before being emitted outwards. The light emitted from the light-emitting lens is collimated light. Collimated light refers to light that has been adjusted from divergent to parallel beams after collimation. Collimation is a crucial process in optical systems, ensuring that light remains parallel during propagation. Collimated light features high beam collimation, easy achievement of optical path consistency, and excellent light emission.

[0058] It should be noted that the reflector assembly 3 of the vehicle headlight is typically made of a highly reflective material. It reflects the light emitted from the light source assembly 1 to the corrective lens assembly 4, which then converges the originally divergent light into a parallel beam that enters the light-emitting lens. The reflector assembly 3 acts as a light-focusing element, similar to the principle of a lampshade, concentrating the light to improve the headlight's illumination effect. This allows the light to be more focused in a specific direction, thereby enhancing lighting performance and ensuring driving safety. The corrective lens assembly 4 also has a light-focusing function, reducing light scattering and improving lighting efficiency.

[0059] The second light-emitting module includes a light source assembly 1, a reflector assembly 2, a light-blocking plate assembly 6, and a diffuser lens. One light source assembly 1 corresponds to one reflector assembly 2, one light-blocking plate assembly 6, and one diffuser lens. Light emitted from the light source assembly 1 is reflected by the reflector assembly 2 and then sequentially passes through the light-blocking plate assembly 6 and the diffuser lens before being emitted outwards. The emitted light from the diffuser lens is diffused light. The diffused light scatters outwards, widening the light range. Areas that were originally not illuminated are now illuminated after diffusion, resulting in better lighting uniformity and preventing the formation of dark areas.

[0060] It should be noted that the headlight's light-blocking component 6 can block some of the light from the reflector component 2, preventing excessive light concentration and also serving as an anti-glare device, while reflecting the remaining light to the diffuser lens.

[0061] It should also be noted that the aforementioned light source assembly 1 is used to provide initial light and can be an LED lamp, halogen lamp, or other suitable light source. The reflector bowl assembly 2 is mounted on the light source assembly 1 and located away from the projection lens assembly 5. The reflector bowl assembly 2 is mainly used to converge the light source, using the reflective surface of the reflector bowl to change the direction of the light source, allowing the light to converge in a specific direction. Each light source assembly 1 is located at the focal point of its corresponding reflector bowl assembly 2. The projection lens assembly 5 includes two areas: a light-emitting lens and a diffuser lens. The light-emitting lens area receives light from the corrective lens assembly 4, and the diffuser lens area receives light from the reflector bowl.

[0062] This application provides a lighting device for motor vehicles. For lighting devices with a slender and angled light-emitting surface (i.e., projection lens assembly 5), two types of light-emitting modules are specifically designed: a first light-emitting module for generating a converging light beam and a second light-emitting module for generating a diffused light beam. On one hand, the first light-emitting module emits collimated light, reducing the refracted light on the front and rear surfaces of the projection lens assembly 5, thereby correcting imaging defects caused by the angled imaging lens (i.e., projection lens assembly 5). On the other hand, the second light-emitting module emits diffused light, thus not affecting the illumination width and avoiding problems such as uneven light distribution and inconsistent light color between the left and right illumination units.

[0063] By combining the optical effects of the first and second light-emitting modules, the coma and chromatic aberration caused by the tilted design can be resolved, ensuring uniformity and width of illumination. This ensures that the light covers a wider area while avoiding glare for oncoming drivers. This design not only provides uniform and wide-area road lighting but also enhances nighttime driving safety.

[0064] In a specific embodiment, the reflector bowl assembly 2 is used to converge the light emitted from the light source assembly 1 to the edge or near the edge of the reflector assembly 3 and the light-blocking assembly 6, which can precisely control the distribution of light, concentrate the light on the area that needs illumination, and reduce unnecessary light scattering. The edge shape of the reflector assembly 3 and the light-blocking assembly 6 determines the emission direction and distribution range of the light.

[0065] Furthermore, the edge of the reflector assembly 3 includes a low beam cutoff line shape; correspondingly, the edge of the light-blocking assembly 6 includes a low beam cutoff line shape. This configuration creates a clear boundary between light and dark areas on the road, distinguishing illuminated and unilluminated areas and ensuring that light does not shine into the eyes of oncoming drivers, thus avoiding glare. By designing it to include a low beam cutoff line shape, a more uniform and reasonable lighting distribution can be achieved.

[0066] In a further specific embodiment, the edge shape of the reflector assembly 3 can be any shape, such as a straight line, a curve, or a broken line. The edge shape of the light-blocking assembly 6 can also be any shape, such as a straight line, a curve, or a broken line. The light-blocking assembly 6 can be fixed by a lens bracket.

[0067] In a specific embodiment, the number of first light-emitting modules can be one or more, and the number of second light-emitting modules can be one or more. Multiple first light-emitting modules are arranged adjacent to each other. Multiple second light-emitting modules are arranged on both sides of the first light-emitting modules. The positional relationship of the multiple second light-emitting modules can be adjusted according to different requirements, such as side-by-side arrangement, spaced-out arrangement, or staggered arrangement, but mutual interference of their light rays should be avoided.

[0068] By complementing the functions of the two modules, the light source at the center can be concentrated and evenly distributed, while the light on both sides diffuses outward, thus expanding the illumination range. The number of the first and second light-emitting modules can be adaptively selected according to actual lighting needs. The light sources of the two modules are structurally independent but complementary in optical effect.

[0069] In a specific embodiment, the light source assembly 1 includes multiple light source groups, the reflector bowl assembly 2 includes multiple reflector bowls, the reflector sheet assembly 3 includes at least one reflector sheet, the corrective lens assembly 4 includes at least one corrective lens, and the light-blocking sheet assembly 6 includes at least one light-blocking sheet.

[0070] like Figure 2As shown, five light-emitting modules are designed according to the light propagation path, including two first light-emitting modules and three second light-emitting modules. Multiple light source components 1 are the first light source group 101, the second light source group 102, the third light source group, the fourth light source group, and the fifth light source group 105. Multiple reflector bowl components 2 are the first reflector bowl 201, the second reflector bowl 202, the third reflector bowl 203, the fourth reflector bowl 204, and the fifth reflector bowl 205. Multiple reflector sheet components 3 are the first reflector sheet 301 and the second reflector sheet 302. Multiple corrective lens components 4 are the first corrective lens 401 and the second corrective lens 402. Multiple light-blocking sheet components 6 are the first light-blocking sheet 601, the second light-blocking sheet 602, and the third light-blocking sheet 603. Multiple projection lens components 5 are the first projection lens 501, the second projection lens 502, the third projection lens 503, the fourth projection lens 504, and the fifth projection lens 505.

[0071] Figures 3-5 One of the first light-emitting modules includes a first light source group 101, a first reflector bowl 201, a first reflector sheet 301, a first corrective lens 401, and a first projection lens 501, wherein the first projection lens 501 is the light-emitting lens.

[0072] Figures 6-8 Another first light-emitting module includes a second light source group 102, a second reflector bowl 202, a second reflector sheet 302, a second corrective lens 402, and a second projection lens 502, the second projection lens 502 being the light-emitting lens.

[0073] The two first light-emitting modules operate on the same principle of light transmission, and their structures may be identical or slightly different, such as... Figure 2 As shown, there are two first reflector bowls 201, and correspondingly, there are two first light source groups 101. The first reflector 301, the first corrective lens 401, and the first projection lens 501 can each be one. There are three second reflector bowls 202, and correspondingly, there are three second light source groups 102. The second reflector 302, the second corrective lens 402, and the second projection lens 502 can each be one. The reflector bowls and light source groups correspond one-to-one.

[0074] Figures 9-11One of the second light-emitting modules includes a fifth light source group 105, a fifth reflector bowl 205, a third light-blocking plate 603, and a fifth projection lens 505, which is also a diffuser lens. The other two second light-emitting modules are identical to the above-described modules. Similarly, another second light-emitting module includes a third light source group, a third reflector bowl 203, a first light-blocking plate 601, and a third projection lens 503, which is also a diffuser lens. The last second light-emitting module includes a fourth light source group, a fourth reflector bowl 204, a second light-blocking plate 602, and a fourth projection lens 504, which is also a diffuser lens.

[0075] Based on fundamental knowledge of geometric optics, the object point and image point of the above lens can be designed with the following parameters:

[0076] Each corrective lens assembly 4 uses a point on its corresponding reflector assembly 3 as its object point in both the horizontal and vertical planes. Specifically, a point on the near-light cutoff line of the reflector assembly 3 can be used as the object point.

[0077] The corrective lens assembly 4 forms two image points in the horizontal and vertical planes respectively: a horizontal image point and a vertical image point. The horizontal image point of each corrective lens assembly 4 in the horizontal plane is located at a predetermined infinity distance in front of the corrective lens assembly 4. The vertical image point of each corrective lens assembly 4 in the vertical plane is located at a predetermined infinity distance in front of the corrective lens assembly 4 or at a predetermined distance behind the corrective lens assembly 4.

[0078] Presetting the image point at infinity in front essentially utilizes the focal point characteristic to generate parallel light or optimize long-distance imaging. By using a point behind the corrective lens assembly 4 as the vertical image point, and correcting aberrations (such as astigmatism and field curvature) and optimizing the optical path, the vertical image point is preset at a specific distance. The core purpose is to achieve high-precision imaging at the target position, meeting the requirements of professional optical systems for sharpness and aberration control.

[0079] Of course, the horizontal and vertical image points of the corrective lens may or may not coincide. The position of the image point of the corrective lens can be anywhere behind or in front of the corrective lens.

[0080] Furthermore, the light-emitting lens uses the corresponding horizontal and vertical image points of the corrective lens assembly 4 as object points in the horizontal and vertical planes, respectively. Both the horizontal and vertical image points of the light-emitting lens are located at a predetermined infinity distance in front of the light-emitting lens; specifically, they can be set at a distance of 25 meters in front of the light-emitting lens. Setting the image point of the headlight's light-emitting lens at infinity in front, compared to setting it at infinity behind, significantly improves lighting performance, reduces glare risk, enhances light penetration, improves the flexibility and aesthetics of the optical system, and complies with regulatory requirements.

[0081] Of course, the horizontal and vertical image points of the aforementioned light-emitting lens may or may not coincide.

[0082] like Figure 4 The diagram shows the horizontal light propagation of the first light-emitting module. The first corrective lens 401 uses a point on the edge of the first reflector 301 as its object point and infinity as its horizontal image point. The first projection lens 501 (i.e., the light-emitting lens) uses the horizontal image point of the first corrective lens 401 as its object point, and the horizontal image point of the first projection lens 501 is located at infinity in front of the first projection lens 501.

[0083] like Figure 5 The diagram shows the vertical plane light propagation of the first light-emitting module. The first corrective lens 401 uses a point on the edge of the first reflector 301 as its object point and infinity as its vertical image point. The first projection lens 501 uses the vertical image point of the first corrective lens 401 as its object point, and the vertical image point of the first projection lens 501 is located at infinity in front of the first projection lens 501.

[0084] like Figure 7 The diagram shows the horizontal light propagation of another first light-emitting module. The second corrective lens 402 uses a point on the edge of the second reflector 302 as its object point, and a point 25m in front of the second corrective lens 402 as its horizontal image point. The second projection lens 502 uses the horizontal image point of the second corrective lens 402 as its object point, and the horizontal image point of the second projection lens 502 is located 25m in front of the second projection lens 502.

[0085] like Figure 8 The diagram shows the vertical plane light propagation of another first light-emitting module. The second corrective lens 402 uses a point on the edge of the second reflector 302 as its object point and a point behind the second corrective lens 402 as its vertical image point. The second projection lens 502 uses the vertical image point of the second corrective lens 402 as its object point, and the vertical image point of the second projection lens 502 is located 25m in front of the second projection lens 502.

[0086] The object point of the diffuser lens on the horizontal plane is located at an infinity distance behind the diffuser lens. The object point of the diffuser lens on the vertical plane is a point on the light-blocking plate assembly 6 corresponding to the diffuser lens. In particular, the object point of the diffuser lens on the vertical plane can be set at a point on the cutoff line of the corresponding light-blocking plate assembly 6.

[0087] The object point on the horizontal plane is positioned at infinity behind the diffuser lens, such as... Figure 10As shown, a light beam diffuses outward on a horizontal plane, similar to a high beam design, enabling illumination over longer distances, more uniform light distribution, and reduced glare risk. The object point of the diffuser lens on the vertical plane is set at a point on the light-blocking assembly 6 in front of the diffuser lens, such as... Figure 11 As shown, it generates parallel beams of light in a vertical plane, similar to the design of low beam headlights, which can form a clear cutoff line and avoid dazzling oncoming vehicles.

[0088] The horizontal image point of the diffuser lens in the horizontal plane is located at a point behind the diffuser lens, and the vertical image point of the diffuser lens in the vertical plane is located at a predetermined infinity distance in front of the diffuser lens. In particular, it can be located 25m in front of the diffuser lens.

[0089] like Figure 10 The diagram shows the horizontal plane light propagation of the second light-emitting module. The fifth projection lens 505 uses infinity behind it as the object point and a certain point behind it as the horizontal image point. Figure 11 The diagram shows the vertical plane light propagation of the second light-emitting module. The fifth projection lens 505 takes a point on the edge of the third light-blocking plate 603 as the object point and a point 25m in front of the fifth projection lens 505 as the vertical image point.

[0090] Furthermore, the corrective lens assembly 4 or the projection lens assembly 5 is provided with a patterned structure that can refract or totally reflect light into the near-light regulation zone 3 and its vicinity.

[0091] It should be noted that the horizontal plane referred to in this article is one that passes through the object point and is parallel to the ground; the vertical plane referred to in this article is one that passes through the object point and is formed by the normal of the horizontal plane and the vehicle's direction of travel. "In front of the lens" refers to the space in which light propagates before entering the lens; "behind the lens" refers to the space in which light propagates after exiting the lens.

[0092] It should also be noted that in optical lenses, "infinity" is an idealized concept used to describe situations where the distance to an object is much greater than the lens's focal length. In practical applications, when the distance to an object reaches tens, hundreds, or even thousands of times the lens's focal length, the object can be approximated as being at infinity. This design is widely used in microscopes and photographic lenses, improving image quality, facilitating the addition of optical components, and enabling standardized design. Therefore, the preset infinity distance referred to in this case can be a specific distance value that is more than ten times the corresponding lens's focal length, depending on the required illumination. For example, the preset infinity distance can be in the range of 10m-35m, specifically 20m, 25m, 26m, 27m, or 30m.

[0093] In a specific embodiment, to simplify installation, the reflector assembly 3 and the corresponding reflector bowl assembly 2 are integrated into one unit. Similarly, the light-blocking sheet assembly 6 and the corresponding reflector bowl assembly 2 are integrated into one unit.

[0094] In summary, the lighting device provided by this solution not only ensures the illumination brightness within the tilted light-emitting area but also widens the horizontal illumination area and improves the light output brightness of the LED lamps. By controlling the projection angle of the light from each light-emitting module, the light output effect is optimized, correcting the imaging defects caused by the tilted shape and avoiding glare for drivers of oncoming vehicles.

[0095] Furthermore, this utility model also provides a vehicle including a lighting device for a motor vehicle as described in the specific embodiments above. Obviously, a vehicle with the above-described lighting device has the same beneficial effects, which will not be elaborated upon here.
