Description

Technical Field

[0001] This application relates to the field of automotive lighting technology, and in particular to an automotive lighting fixture and a vehicle using the same lighting fixture. Background Technology

[0002] Vehicle lights provide illumination for vehicles, and their optical performance and structural design directly affect driving safety, energy efficiency, and overall vehicle aesthetics. With the increasing demand for lightweight and compact vehicles, optimizing the size and efficiency of vehicle lighting modules has become a key technological challenge.

[0003] In related technologies, the reflective lighting module of vehicle lights usually consists of a light source, a reflector and a baffle light. The baffle is usually located 40 to 50 millimeters in front of the light source to control stray light, while the reflector uses a curved surface to achieve directional light projection.

[0004] However, in the aforementioned headlights, the excessively long baffle distance makes it difficult for the module to fit into a small installation space, resulting in redundancy in the overall structure of the lighting module and increasing material and manufacturing costs; secondly, the insufficient coordination efficiency between the reflector and the baffle leads to some light loss and affects the uniformity of lighting. Utility Model Content

[0005] This application provides a vehicle lamp and a vehicle, which can reduce the space occupied by the vehicle lamp to reduce the manufacturing cost of the vehicle lamp; on the other hand, it can improve the illumination uniformity of the vehicle lamp.

[0006] In a first aspect, this application provides a vehicle lamp, which includes a lighting module, comprising a reflector, a light source, and a baffle; the reflector has a reflective surface, the longitudinal cross-sectional profile of the reflector is a quarter of an ellipse, and the cross-sectional profile of the reflector is a parabola with its opening facing forward; the light source is located below the reflector, and the projection area of ​​the light source on the reflective surface falls within the reflective surface; the baffle is located below the reflector and in front of the light source, and the projection area of ​​the baffle on the reflective surface falls within the reflective surface; wherein the baffle has a light-blocking surface facing the light source, and in the horizontal direction, the distance between the center of the light source and the light-blocking surface is greater than or equal to 3 mm and less than or equal to 8 mm.

[0007] In this way, while ensuring the directional projection function of light, the space utilization of the reflector is optimized, and the distance between the baffle and the light source is reduced compared to related technologies. This not only directly reduces the longitudinal dimension of the lighting module in the vehicle headlight provided in this application, making it more suitable for the needs of modern automobiles for compact lighting modules, but also reduces the energy loss of light during transmission by shortening the optical path.

[0008] Secondly, the combination of the elliptical longitudinal section and the parabolic cross section allows light to converge vertically while remaining collimated horizontally. The positioning of the baffle within the projection area of ​​the reflective surface effectively controls stray light and, to some extent, avoids the problem of excessive light blocking caused by excessive baffle distance in related technologies. The limited distance between the light source center and the light-blocking surface reduces ineffective optical path while ensuring effective light blocking, thus improving illumination uniformity and reducing the amount of material used in the reflector, thereby lowering costs.

[0009] As an optional implementation, the lighting module also includes an inner lens and an outer lens; the inner lens is located in front of the reflector; the outer lens is located in front of the inner lens, and the back cutoff point of the inner lens is located on the central axis plane of the outer lens.

[0010] This allows light rays to initially converge in the inner lens after exiting the reflective surface of the mirror, and then undergo secondary optimization in the central axis region of the outer lens. This not only compensates for the potential light diffusion problem caused by shortening the distance of baffle 3, but also improves the uniformity and edge sharpness of the emitted light pattern.

[0011] Furthermore, the arrangement of the inner lens in front of the reflecting mirror and the outer lens in front of it, together with the special curved surface of the reflecting mirror, forms a deep optical system. This arrangement not only ensures the space requirements for optical path turning but also minimizes the optical path by aligning the back intercept point of the inner lens with the central axis of the outer lens.

[0012] As an optional implementation, the inner lens has a first mirror surface and a second mirror surface arranged opposite to each other, with the first mirror surface facing the reflecting mirror and the second mirror surface facing the outer lens; the second mirror surface is a first arc-shaped surface, and the first arc-shaped surface is concave on the side facing the outer lens; wherein, the thickness of the inner lens first increases and then decreases in the direction from left to right.

[0013] This thickness distribution causes light rays at different positions to experience differentiated optical path changes when passing through the inner lens. The thicker central region enhances the converging ability of the light rays, while the gradually thinning transition areas on both sides ensure a smooth transition of the light field.

[0014] Furthermore, the combination of the concave first arc surface and the thickness variation effectively corrects the astigmatism problem from the mirror, making the focusing characteristics of light more consistent in both the horizontal and vertical dimensions. Moreover, the non-uniform thickness distribution achieves automatic balancing of light intensity, with thicker areas appropriately attenuating the central strong light and thinner areas enhancing the edge brightness. In addition, the aforementioned thickness limitation of the inner lens can also improve light energy utilization and increase the output of effective light flux by precisely controlling the refraction angle of each area.

[0015] Moreover, the distribution pattern of increasing thickness followed by decreasing thickness enhances the structural strength of the inner lens, making it exhibit better dimensional stability when subjected to temperature changes and mechanical vibrations, thereby improving the reliability of the headlight in complex operating environments.

[0016] As an optional implementation, the outer lens has a third mirror surface and a fourth mirror surface arranged opposite to each other, with the third mirror surface facing the inner lens; the fourth mirror surface is a second arc-shaped surface, and the second arc-shaped surface is recessed towards the side opposite to the inner lens; wherein, the thickness of the outer lens first increases and then decreases in the direction from top to bottom, and the thickness of the top end of the outer lens is greater than the thickness of the bottom end of the outer lens.

[0017] In this way, the fourth mirror can work in conjunction with the second mirror to further diffuse or converge the light after it has been refracted by the inner lens, thereby optimizing the beam shape of the overall lighting and making the light distribution more in line with actual lighting needs.

[0018] Secondly, the thickness of the outer lens increases and then decreases from top to bottom, with the thickness at the top being greater than that at the bottom. This thickness variation design, combined with its own curved mirror surface, can specifically adjust the refraction angle of light in different areas, thus avoiding the problem of uniform light refraction effect caused by uniform thickness to a certain extent.

[0019] Meanwhile, the thicker design at the top complements the thickness variation of the inner lens, which increases and then decreases from left to right. Combined with the reflective effect of the elliptical quarter-section and parabolic cross-section of the reflector, as well as the position of the light source and the baffle, the light emitted from the light source is reflected by the reflector, the baffle effectively blocks stray light, and the inner lens initially refracts the light. Then, through the differentiated thickness and curved mirror surface of the outer lens, a more uniform and suitable lighting effect is achieved, reducing glare or blind spots and improving the overall lighting performance of the headlights.

[0020] As an optional implementation, there are multiple reflectors, which are arranged side by side and connected together in the left-right direction, forming a reflector unit; there are multiple light sources, which are arranged one-to-one with the multiple reflectors; there are multiple baffles, which are arranged one-to-one with the multiple reflectors, and are arranged side by side and connected together in the left-right direction; there are multiple inner lenses, which are arranged one-to-one with the multiple reflectors, and are connected together, forming an inner lens unit; there are multiple outer lenses, which are arranged one-to-one with the multiple inner lenses, and are connected together, forming an outer lens unit.

[0021] In this way, each reflector, together with its corresponding light source and baffle, forms an independent basic lighting unit. The light is then adjusted by the corresponding inner and outer lenses, ensuring more precise light processing for each unit. This also avoids interference between different units to a certain extent and improves the lighting stability of a single unit.

[0022] Secondly, multiple reflectors, baffles, inner lenses, and outer lenses are connected side by side along the left and right directions, which can integrate multiple independent lighting units into a whole structure, enhance the structural stability of the lighting module, reduce installation errors or loosening problems caused by the scattered placement of various components, and facilitate the overall assembly and maintenance of the vehicle lights provided in this embodiment.

[0023] Furthermore, this layout of multiple lighting units side by side, combined with the connection design of each component, allows for wider illumination coverage in the left and right directions by adjusting the brightness of the light source of different lighting units, the angle of the reflector, or the curvature of the lens, and can form a gradual or zoned lighting effect according to actual needs.

[0024] As an optional implementation, the reflector unit includes a left reflector located on the left and a right reflector located on the right; wherein, the cross-sectional profile of the left reflector is a first parabola with the opening facing the right front; and the cross-sectional profile of the right reflector is a second parabola with the opening facing the left front.

[0025] First, the parabolic openings of the left and right reflectors face each other forward, so that the light reflected by the left reflector is mainly concentrated to the right front, and the light reflected by the right reflector is mainly concentrated to the left front. The two reflectors form a certain overlapping coverage area, which can effectively expand the illumination range of the headlights in the left and right directions and avoid the problem of insufficient illumination on both sides due to reflection in a single direction.

[0026] Secondly, this parabolic design with differentiated directions can work in conjunction with corresponding light sources and baffles to allow light emitted from the left light source to be reflected by the left reflector and form more precise illumination on the right front, and light emitted from the right light source to be reflected by the right reflector and form more precise illumination on the left front, reducing excessive superposition of light in the middle area. At the same time, by blocking stray light through the baffle, glare in the intersection area can be avoided to a certain extent.

[0027] Furthermore, with the structure of the inner and outer lenses, the light reflected by the left and right reflectors is initially refracted by the corresponding inner lenses, and then further adjusted by the curved surface and thickness variation of the outer lenses. This makes the light distribution in the overlapping coverage area more uniform, and creates a reasonable transition in lighting intensity between the middle area and the two side areas. This improves the lighting adaptability of the vehicle lamp provided in this embodiment under curves or complex road conditions, ensuring that the light in different positions can meet the actual lighting needs.

[0028] As an optional implementation, the multiple baffles include a left baffle and a right baffle, with the left baffle corresponding to the left reflector and the right baffle corresponding to the right reflector; the left baffle has a first light-blocking surface facing the corresponding light source and the right baffle has a second light-blocking surface facing the corresponding light source; wherein, the first light-blocking surface faces the left rear and the second light-blocking surface faces the right rear.

[0029] In this way, the first light-blocking surface of the left baffle faces the left rear, which can specifically block stray light emitted by the left light source towards the left rear area of ​​the left reflector, and to a certain extent avoid unnecessary scattering after these lights are reflected by the reflector; similarly, the second light-blocking surface of the right baffle faces the right rear, which can effectively block stray light emitted by the right light source towards the right rear area of ​​the right reflector, and reduce the interference of stray light on the effective beam.

[0030] Secondly, the directional restrictions of the first and second light-blocking surfaces mentioned above are compatible with the characteristics of the first parabolic opening of the cross-section of the left reflector facing to the right front and the second parabolic opening of the cross-section of the right reflector facing to the left front. The light-blocking direction of the left baffle is complementary to the light reflection direction of the left reflector, and the light-blocking direction of the right baffle is complementary to the light reflection direction of the right reflector. This can not only avoid the first and second light-blocking surfaces from excessively blocking the effective light to a certain extent, but also filter out stray light that deviates from the expected path, so that the light reflected by the left and right reflectors is more in line with the designed propagation trajectory, providing a more stable incident beam basis for the subsequent light adjustment of the inner and outer lenses.

[0031] Furthermore, the overall structure of multiple baffles connected side by side in the left and right directions, combined with the light-blocking surface design of the left and right baffles, can form a continuous light-blocking area in the left and right directions that is adapted to each of the reflectors. This reduces light crosstalk between adjacent reflectors, ensures that the beams of multiple lighting units maintain their independence and accuracy, and improves the lighting uniformity and effectiveness of the vehicle lights provided in this embodiment. Especially in the layout of multiple units side by side, it can avoid the problem of local over-brightness or dark areas caused by stray light interference to a certain extent.

[0032] As an alternative implementation, in the left-right direction, the length of the reflector unit is equal to the length of the inner lens unit, and the length of the outer lens unit is less than the length of the inner lens unit.

[0033] The design that the reflector unit and the inner lens unit maintain the same length in the left-right direction ensures the integrity and continuity of the light path transmission, so that the light emitted from the reflector surface can be completely received and processed by the inner lens, thus avoiding the problem of light energy loss caused by length mismatch to a certain extent.

[0034] Meanwhile, the moderate reduction in the size of the outer lens unit, without sacrificing the effective illumination area, leaves room for the installation of other structures around the illumination module. Furthermore, aligning the lengths of the reflector unit and the inner lens unit simplifies the assembly positioning reference, while the appropriate reduction in the size of the outer lens unit reduces tolerance sensitivity.

[0035] It should be noted that the reduction in the length of the outer lens unit does not affect the effective illumination range. On the contrary, the extension of the inner lens unit creates a natural optical transition zone, ensuring both the brightness uniformity of the core illumination area and achieving a halo effect. Thus, the headlight provided in this embodiment not only meets regulatory light pattern requirements but also better integrates into the overall vehicle styling.

[0036] As an optional implementation, the mirror unit has a first central axis extending in the front-back direction, the inner lens unit has a second central axis extending in the front-back direction, and the outer lens unit has a third central axis extending in the front-back direction. The projections of the first central axis, the second central axis, and the third central axis on the horizontal plane coincide.

[0037] This allows light rays emitted from the reflective surface of the mirror to pass sequentially through the inner and outer lenses along the designed path, reducing optical path deflection errors and improving optical efficiency. Moreover, the coincidence of the central axis projection not only optimizes light energy utilization but also creates a compact axial layout space.

[0038] Furthermore, the composite curved surface optical properties of the mirror can be fully inherited and optimized in both the inner and outer lenses, ensuring precise control of light in both horizontal and vertical dimensions. The special thickness gradient characteristics of the inner lens complement the elliptical-parabolic composite curved surface of the mirror, jointly correcting astigmatism and field curvature problems. The moderate shortening of the outer lens unit achieves optical trimming within the framework of central axis alignment, which not only meets regulatory light pattern requirements but also creates unique visual characteristics.

[0039] Furthermore, the coincidence of the projections of the first, second, and third center axes provides an intuitive alignment reference for the assembly process, improving assembly accuracy and reducing the adverse effects of tolerance accumulation. In particular, center axis alignment does not increase manufacturing costs; instead, it reduces the manufacturing cost of the headlights provided in this embodiment by simplifying positioning tooling and inspection processes. Simultaneously, the coincidence of center axis projections effectively disperses mechanical stress, keeping the optical axis offset under vibration conditions within a small angular range.

[0040] As an alternative implementation, the top of the inner lens unit is flush with the top of the outer lens unit, and the top of the reflecting mirror unit is higher than the top of the inner lens unit.

[0041] The top of the inner lens unit is flush with the top of the outer lens unit, allowing light modulated by the inner lens to smoothly transition to the outer lens, reducing light energy loss and improving the edge sharpness of the emitted light pattern. The arrangement of the top of the reflecting mirror unit being higher than the top of the inner lens unit provides ample space for the reflected light path, enabling the composite surface of the reflecting mirror to fully utilize its optical properties and increasing the effective reflective area.

[0042] Furthermore, the flush relationship between the top of the inner lens unit and the top of the outer lens unit ensures a seamless connection of the optical processing chain, avoiding light diffraction problems to a certain extent. In particular, the raised design of the top of the reflector unit cleverly utilizes the space above the headlight, allowing the reflector to adopt a larger radius of curvature. This not only increases the high beam illumination distance but also improves the uniformity of light intensity in the central area.

[0043] Furthermore, the flush top of the inner lens unit with the top of the outer lens unit simplifies the design of the front sealing structure and reduces the complexity of waterproofing; while the independent height setting of the reflector unit provides ample space for its connection mechanism and heat dissipation channel. The elevated layout of the reflector promotes natural air convection, which can reduce the operating temperature of critical components.

[0044] As an optional implementation, the vehicle lamp provided in this application also includes a circuit board assembly; wherein the light source is disposed on the circuit board assembly.

[0045] As an optional implementation, the vehicle light provided in this application also includes a radiator, which is disposed below the circuit board assembly and abuts against the circuit board assembly; wherein the baffle and the radiator are an integral structure.

[0046] The baffle, as an extension of the heat sink, not only performs optical control functions but also serves as a key component of the heat conduction path, increasing the heat dissipation area while reducing the number of parts. Heat generated by the light source is directly transferred to the heat sink below via the circuit board assembly, and the integrated design of the baffle and heat sink further shortens the heat conduction path, enabling rapid reduction of the operating temperature of critical components.

[0047] Furthermore, the one-piece molded baffle and heat sink eliminate connection gaps, which not only improves the overall structural rigidity and reduces displacement under vibration conditions, but also avoids connection stress problems caused by differences in the thermal expansion coefficients of materials to a certain extent. In particular, as an upper extension of the heat sink, the baffle's special position precisely enhances the heat dissipation of the light source area. This design reduces the peak junction temperature of the light source and extends its service life.

[0048] In addition, the baffle and radiator are formed in one piece by die casting or precision injection molding, which not only simplifies the production process, but also shortens the assembly time and improves the dimensional consistency between components.

[0049] Furthermore, the direct contact design between the heat sink and the circuit board assembly creates an efficient thermal path from the light source to the external environment. This ensures excellent optical performance of the headlights while meeting the reliability requirements of modern automotive electronics for high-power-density lighting systems, thus improving the operational stability of the headlights.

[0050] Secondly, this application also provides a vehicle, including a body and the aforementioned vehicle lights, the vehicle lights being mounted on the body.

[0051] The vehicle provided in this application, by adopting the aforementioned headlights, has low manufacturing costs and good performance. Attached Figure Description

[0054] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0055] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0056] Vehicle lights provide illumination for vehicles, and their optical performance and structural design directly affect driving safety, energy efficiency, and overall vehicle aesthetics. With the increasing demand for lightweight and compact vehicles, optimizing the size and efficiency of lighting modules has become a key technological challenge.

[0057] In related technologies, reflective lighting modules for automotive headlights typically consist of a light source, a reflector, and a baffle light. The baffle is usually located 40-50mm in front of the light source to control stray light, while the reflector uses a curved surface to direct light projection. In this design, the large distance between the light source and the baffle significantly increases the module's longitudinal dimensions. While the curved shape of the reflector can focus light, it sacrifices compactness due to the need to adapt to the distant baffle. Furthermore, the complex molding process of traditional reflectors further increases costs. Therefore, the structure of the aforementioned lighting module has the following drawbacks: First, the excessively long baffle distance makes the module difficult to fit into narrow installation spaces, resulting in redundant overall structure and increased material and manufacturing costs. Second, the insufficient coordination efficiency between the reflector and the baffle leads to some light loss, affecting lighting uniformity.

[0058] Based on this, this application provides a vehicle lamp and a vehicle, wherein the reflector in the vehicle lamp is formed by combining an elliptical contour line and a parabolic contour line to form the outer surface of the reflector, and the distance between the light-blocking surface of the baffle and the center of the light source is greater than or equal to 3 mm and less than or equal to 8 mm. This configuration, on the one hand, can reduce the space occupied by the vehicle lamp, thereby reducing the manufacturing cost of the vehicle lamp; on the other hand, it can improve the illumination uniformity of the vehicle lamp.

[0059] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific implementation details.

[0060] Please see Figures 1 to 3 , Figure 1 This is a three-dimensional structural diagram of the lighting module in the vehicle headlight provided in the embodiments of this application. Figure 2 This is a schematic diagram of the planar structure of the lighting module in the vehicle headlight provided in an embodiment of this application. Figure 3 for Figure 2 A schematic diagram of the planar structure from viewpoint A.

[0061] As shown in the figure, this embodiment provides a vehicle light, including a lighting module 10. The lighting module 10 includes a reflector 1, a light source 2, and a baffle 3. The reflector 1 has a reflective surface 11, and the longitudinal cross-sectional profile of the reflector 1 is a quarter of an ellipse. The cross-sectional profile of the reflector 1 is a parabola with its opening facing forward. The light source 2 is located below the reflector 1, and the projection area of ​​the light source 2 on the reflective surface 11 falls within the reflective surface 11. The baffle 3 is located below the reflector 1 and in front of the light source 2. The projection area of ​​the baffle 3 on the reflective surface 11 falls within the reflective surface 11. The baffle 3 has a light-blocking surface 31 facing the light source 2. In the horizontal direction, the distance between the center of the light source 2 and the light-blocking surface 31 is greater than or equal to 3 mm and less than or equal to 8 mm.

[0062] In this way, while ensuring the directional projection function of light, the space utilization of the reflector 1 is optimized, and the distance between the baffle 3 and the light source 2 is reduced compared with related technologies. This not only directly reduces the longitudinal dimension of the lighting module 10 in the vehicle headlight provided in this embodiment, making it more suitable for the needs of modern automobiles for compact lighting modules, but also reduces the energy loss of light during transmission by shortening the optical path.

[0063] Secondly, the combination of the elliptical longitudinal section and the parabolic cross section allows light to converge vertically while remaining collimated horizontally. The positioning of the baffle 3 within the projection area of ​​the reflecting surface 11 effectively controls stray light and, to some extent, avoids the problem of excessive light blocking caused by excessive distance between the baffle and other technologies. Furthermore, the limited distance between the center of the light source 2 and the light-blocking surface 31 reduces ineffective optical path while ensuring effective light blocking, thus improving illumination uniformity and reducing the material usage of the reflector 1, thereby lowering costs.

[0064] It should be noted that in some specific embodiments, the light source 2 described above can be an LED light panel. Here, there is no specific limitation on the type of light source 2.

[0065] It is understandable that a smaller distance between the light-blocking surface 31 and the center of the light source 2 is more in line with the design concept of small spaces. Therefore, the distance between the light-blocking surface 31 and the center of the light source 2 can be 3 mm, 3.1 mm, 3.2 mm, 3.3 mm, 3.4 mm, 3.5 mm, 3.6 mm, 3.7 mm, 3.8 mm, 3.9 mm, 4.0 mm, etc. Of course, the distance between the light-blocking surface 31 and the center of the light source 2 can be any value within the above range. Here, the distance between the light-blocking surface 31 and the center of the light source 2 is not specifically limited.

[0066] Furthermore, to improve the light emission uniformity of the illumination module 10, the illumination module 10 also includes an inner lens 4 and an outer lens 5; the inner lens 4 is located in front of the reflector 1; the outer lens 5 is located in front of the inner lens 4, and the back intercept of the inner lens 4 is located on the central axis plane of the outer lens 5. This allows light emitted from the reflecting surface 11 of the reflector 1 to undergo initial convergence in the inner lens 4, followed by secondary optimization in the central axis region of the outer lens 5. This not only compensates for the light diffusion problem that may be caused by shortening the distance of the baffle 3, but also improves the uniformity and edge sharpness of the emitted light pattern.

[0067] Furthermore, the arrangement of the inner lens 4 in front of the reflector 1 and the outer lens 5 in front of it, together with the special curved surface of the reflector 1, forms a deep optical system. This arrangement not only ensures the space requirements for optical path turning, but also minimizes the optical path by aligning the rear intercept point of the inner lens 4 with the central axis of the outer lens 5.

[0068] Please continue to combine Figure 4 and Figure 5 , Figure 4 for Figure 2 The light pattern of the lighting module from the shown viewpoint. Figure 5 for Figure 3 The diagram shows the light path of the illumination module from the indicated perspective. The arrows indicate the direction of the light. In some embodiments, to improve the illumination effect of the illumination module 10, the inner lens 4 has a first mirror surface 41 and a second mirror surface 42 arranged opposite to each other. The first mirror surface 41 faces the reflecting mirror 1, and the second mirror surface 42 faces the outer lens 5. The second mirror surface 42 is a first arc-shaped surface, and the side of the first arc-shaped surface facing the outer lens 5 is concave. The thickness of the inner lens 4 increases first and then decreases from left to right. This thickness distribution causes light rays at different positions to experience differentiated optical path changes when passing through the inner lens 4. The thicker central region enhances the converging ability of the light, while the gradually thinning transition areas on both sides ensure a smooth transition of the light field.

[0069] Furthermore, the combination of the concave first arc surface and the thickness variation effectively corrects the astigmatism problem from the reflector 1, making the focusing characteristics of light more consistent in both the horizontal and vertical dimensions; moreover, the non-uniform thickness distribution achieves automatic balancing of light intensity, with thicker areas appropriately attenuating the central strong light and thinner areas enhancing the edge brightness; in addition, the aforementioned thickness limitation of the inner lens 4 can also improve light energy utilization, and by precisely controlling the refraction angle of each area, the output of effective light flux can be increased.

[0070] Moreover, the distribution pattern of increasing thickness followed by decreasing thickness enhances the structural strength of the inner lens 4, making it exhibit better dimensional stability when subjected to temperature changes and mechanical vibrations, thereby improving the reliability of the headlight in complex operating environments.

[0071] It should be noted that the aforementioned forward / backward, up / down, and left / right directions can all be referenced. Figures 1 to 5 The direction in.

[0072] Regarding the shape of the outer lens 5, it can have a third mirror surface 51 and a fourth mirror surface 52 arranged opposite to each other. The third mirror surface 51 faces the inner lens 4; the fourth mirror surface 52 is a second arc-shaped surface, and the second arc-shaped surface is concave towards the side opposite to the inner lens 4. The thickness of the outer lens 5 first increases and then decreases from top to bottom, and the thickness at the top of the outer lens 5 is greater than the thickness at the bottom. In this way, the fourth mirror surface 52 can cooperate with the second mirror surface 42 to further diffuse or converge the light after it has been refracted by the inner lens 4, thereby optimizing the beam shape of the overall illumination and making the light distribution more in line with the actual illumination requirements.

[0073] Secondly, the thickness of the outer lens 5 increases and then decreases from top to bottom, with the thickness at the top being greater than that at the bottom. This thickness variation design, combined with its own curved mirror surface, can specifically adjust the refraction angle of light in different areas, thus avoiding the problem of uniform light refraction effect caused by uniform thickness to a certain extent.

[0074] Meanwhile, the thicker design at the top complements the thickness variation of the inner lens 4, which increases and then decreases from left to right. Combined with the reflective effect of the elliptical quarter-section and parabolic cross-section of the reflector 1, as well as the position of the light source 2 and the baffle 3, the light emitted from the light source 2 is reflected by the reflector 1, properly blocked by the baffle 3, initially refracted by the inner lens 4, and then passed through the differentiated thickness and curved mirror surface of the outer lens 5. This ultimately achieves a more uniform and suitable lighting effect, reduces glare or lighting dead angles, and improves the overall lighting performance of the lighting module 10.

[0075] To further enhance the lighting effect of the lighting module 10, in some optional embodiments, there are multiple reflectors 1, arranged side-by-side and connected together in the left-right direction, forming a reflector unit 20; multiple light sources 2, each corresponding to one of the multiple reflectors 1; multiple baffles 3, each corresponding to one of the multiple reflectors 1, arranged side-by-side and connected together in the left-right direction; multiple inner lenses 4, each corresponding to one of the multiple reflectors 1, connected together, forming an inner lens unit 30; and multiple outer lenses 5, each corresponding to one of the multiple inner lenses 4, connected together, forming an outer lens unit 40. This allows each reflector 1, in conjunction with its corresponding light source 2 and baffle 3, to form an independent basic lighting unit. The light is then adjusted by the corresponding inner lens 4 and outer lens 5, ensuring more precise light processing for each unit, minimizing interference between different units, and improving the lighting stability of a single unit.

[0076] Secondly, multiple reflectors 1, baffles 3, inner lenses 4 and outer lenses 5 are connected side by side along the left and right directions, which can integrate multiple independent lighting units into a whole structure, enhance the structural stability of the vehicle lamp provided in this embodiment, reduce installation errors or loosening problems caused by the scattered placement of various components, and facilitate the overall assembly and maintenance of the vehicle lamp.

[0077] Furthermore, this layout of multiple lighting units side by side, combined with the connection design of each component, can achieve a wider range of lighting coverage in the left and right directions by adjusting the brightness of the light source 2 of different lighting units, the angle of the reflector 1, or the curvature of the lens, and can form a gradual or zoned lighting effect according to actual needs.

[0078] To ensure the light-blocking effect of the baffle 3 while preventing interference between the connection of adjacent baffles 3 and the connection of adjacent reflectors 1, a clearance notch 32 can be formed on the baffle 3. The clearance notch 32 is opposite to the connection point of two adjacent reflectors 1. The arrangement of the clearance notch 32 first solves the most critical assembly interference problem of multiple reflectors 1, providing physical clearance space for the connection structure between adjacent reflectors 1, so that multiple reflectors 1 can be arranged closely with minimal gaps, improving the space utilization of the lighting module 10.

[0079] Furthermore, the relative position of the clearance notch 32 to the connection point of the reflector 1 ensures that the basic blocking function of the baffle 3 against stray light is not affected, while also avoiding excessive cutting of the effective reflected light to a certain extent. Moreover, the boundary of the clearance notch 32 is precisely aligned with the boundary of the effective reflection area of ​​the reflector 1, forming a natural optical transition zone, which makes the edge transition of the illumination light pattern more natural and soft.

[0080] Furthermore, the correspondence between the position of the clearance notch 32 and the connection point of the reflector 1 simplifies the assembly positioning process. By using the clearance notch 32 as a visual alignment mark, assembly accuracy can be improved. At the same time, this modular clearance design reduces the injection molding difficulty of the baffle 3 and improves production yield.

[0081] Furthermore, the introduction of the clearance notch 32 improves the heat dissipation performance of the lighting module 10, provides an additional airflow channel for the connection area of ​​the reflector 1, and enables the operating temperature of key parts to drop, effectively extending the service life of optical components.

[0082] It should be noted that in this embodiment, multiple inner lenses 4 are integrally formed, so that the first mirror surfaces 41 of multiple inner lenses 4 are connected to form a complete plane; similarly, multiple outer lenses 5 are integrally formed, so that the third mirror surfaces 51 of multiple outer lenses 5 are connected to form a complete plane, and the fourth mirror surfaces 52 of multiple outer lenses 5 are connected to form a complete plane.

[0083] Specifically, the reflector unit 20 includes a left reflector 1A located on the left and a right reflector 1B located on the right; wherein, the cross-sectional profile of the left reflector 1A is a first parabola with the opening facing the right front; the cross-sectional profile of the right reflector 1B is a second parabola with the opening facing the left front.

[0084] First, the parabolic openings of the left reflector 1A and the right reflector 1B face each other forward, so that the light reflected by the left reflector 1A is mainly concentrated to the right front, and the light reflected by the right reflector 1B is mainly concentrated to the left front. The two form a certain overlapping coverage area, which can effectively expand the illumination range of the vehicle headlights provided in this embodiment in the left and right directions and avoid the problem of insufficient illumination on both sides due to reflection in a single direction.

[0085] Secondly, this parabolic design with differentiated directions can work in conjunction with the corresponding light source 2 and baffle 3, so that the light emitted by the left light source 2 is reflected by the left reflector 1A and forms more precise illumination on the right front, and the light emitted by the right light source 2 is reflected by the right reflector 1B and forms more precise illumination on the left front, reducing the excessive superposition of light in the middle area. At the same time, by blocking stray light through the baffle 3, glare in the intersection area can be avoided to a certain extent.

[0086] Furthermore, with the structure of the inner lens 4 and the outer lens 5, the light reflected by the left reflector 1A and the right reflector 1B is initially refracted by the corresponding inner lens 4, and then further adjusted by the arc-shaped mirror surface and thickness variation of the outer lens 5. This makes the light distribution in the overlapping coverage area more uniform, and forms a reasonable transition in lighting intensity between the middle area and the two side areas. This improves the lighting adaptability of the vehicle lamp provided in this embodiment under curves or complex road conditions, and ensures that the light in different positions can meet the actual lighting needs.

[0087] More specifically, the multiple baffles 3 include a left baffle 3A and a right baffle 3B. The left baffle 3A corresponds to the left reflector 1A, and the right baffle 3B corresponds to the right reflector 1B. The left baffle 3A has a first light-blocking surface 31A facing the corresponding light source 2, and the right baffle 3B has a second light-blocking surface 31B facing the corresponding light source 2. The first light-blocking surface 31A faces the left rear, and the second light-blocking surface 31B faces the right rear.

[0088] In this way, the first light-blocking surface 31A of the left baffle 3A faces the left rear, which can specifically block the stray light emitted by the left light source 2 to the left rear area of ​​the left reflector 1A, and to a certain extent avoid unnecessary scattering of these lights after being reflected by the reflector 1A; similarly, the second light-blocking surface 31B of the right baffle 3B faces the right rear, which can effectively block the stray light emitted by the right light source 2 to the right rear area of ​​the right reflector 1B, and reduce the interference of stray light on the effective beam.

[0089] Secondly, the directional restrictions of the first light-blocking surface 31A and the second light-blocking surface 31B mentioned above are compatible with the characteristics of the first parabolic opening of the cross-section of the left reflector 1A facing to the right front and the second parabolic opening of the cross-section of the right reflector 1B facing to the left front. The light-blocking direction of the left baffle 3A is complementary to the light reflection direction of the left reflector 1A, and the light-blocking direction of the right baffle 3B is complementary to the light reflection direction of the right reflector 1B. This can not only avoid the first light-blocking surface 31A and the second light-blocking surface 31B from excessively blocking the effective light to a certain extent, but also filter out stray light that deviates from the expected path. This makes the light reflected by the left reflector 1A and the right reflector 1B more in line with the designed propagation trajectory, providing a more stable incident beam basis for the subsequent light adjustment of the inner lens 4 and the outer lens 5.

[0090] Furthermore, the overall structure of multiple baffles 3 connected side by side in the left and right directions, together with the light-blocking surface design of the left baffle 3A and the right baffle 3B, can form a continuous light-blocking area in the left and right directions that is adapted to each of the reflectors 1, reducing light crosstalk between adjacent reflectors 1, ensuring that the beams of multiple lighting units maintain their independence and accuracy, and improving the lighting uniformity and effectiveness of the vehicle lamp provided in this embodiment. Especially in the layout of multiple units side by side, it can avoid the problem of local over-brightness or dark areas caused by stray light interference to a certain extent.

[0091] like Figure 1 As shown, since the first light-blocking surface 31A and the second light-blocking surface 31B are not on the same plane as the other light-blocking surfaces 31, in order to connect multiple baffles 3 together, the left baffle 3A is connected to the adjacent baffle 3 by the first connecting plate 6; the right baffle 3B is connected to the adjacent baffle 3 by the second connecting plate 7. The arrangement of the first connecting plate 6 and the second connecting plate 7 can firmly connect the left baffle 3A, the right baffle 3B, and the adjacent baffles 3 into a whole, preventing individual baffles 3 from shifting due to vibration or other factors during the operation of the headlights. This ensures that the light-blocking surface of each baffle 3 always maintains the relative positional accuracy with the corresponding light source 2 and reflector 1, thus stably performing its light-blocking function. That is, it will not cause incomplete blocking of stray light due to positional displacement, nor will it excessively block effective light, thus ensuring the accuracy of light blocking.

[0092] Moreover, this connection method enables multiple baffles 3 to form a continuous integral structure, filling the gaps between adjacent baffles 3 and preventing light from leaking out of the gaps and forming stray light. Especially for components such as the left reflector 1A and the right reflector 1B with different reflection directions, it can prevent the reflected light from interfering with each other through the gaps in the baffles 3 to a certain extent, ensuring that the beams corresponding to each reflector 1 remain independent, and providing purer incident light for the subsequent light adjustment of the inner lens 4 and the outer lens 5.

[0093] In addition, the overall connected baffle structure facilitates the assembly and maintenance of the lighting module 10, eliminating the need for individual baffles 3 to be positioned and installed one by one, thus improving production efficiency and enhancing the structural strength of the baffles 3, thereby extending their service life.

[0094] like Figure 3 As shown in the specific implementation of this embodiment, in the left-right direction, the length of the reflector unit 20 is the same as the length of the inner lens unit 30, and the length of the outer lens unit 40 is less than the length of the inner lens unit 30. This design, where the reflector unit 20 and the inner lens unit 30 maintain the same length in the left-right direction, firstly ensures the integrity and continuity of the light path transmission, allowing the light emitted from the reflecting surface of the reflector 1 to be completely received and processed by the inner lens 4, thus avoiding light energy loss due to length mismatch to a certain extent.

[0095] Meanwhile, the moderate reduction in the size of the outer lens unit 40, without sacrificing the effective illumination area, leaves room for the installation of other structures around the illumination module 10. Furthermore, aligning the lengths of the reflector unit 20 and the inner lens unit 30 simplifies the assembly positioning reference, while the appropriate reduction in the size of the outer lens unit 40 reduces tolerance sensitivity.

[0096] It should be noted that the reduction in the length of the outer lens unit 40 does not affect the effective illumination range. On the contrary, the extension of the inner lens unit 30 forms a natural optical transition zone, ensuring both the brightness uniformity of the core illumination area and achieving a halo effect. Thus, the vehicle headlight provided in this embodiment not only meets regulatory light pattern requirements but also better integrates into the overall vehicle styling.

[0097] Furthermore, such as Figure 3 As shown, the mirror unit 20 has a first central axis L1 extending in the front-back direction, the inner lens unit 30 has a second central axis L2 extending in the front-back direction, and the outer lens unit 40 has a third central axis L3 extending in the front-back direction. The projections of the first central axis L1, the second central axis L2, and the third central axis L3 on the horizontal plane coincide.

[0098] In this way, the light rays emitted from the reflective surface of mirror 1 can pass through the inner lens 4 and the outer lens 5 sequentially along the designed path, reducing light path deflection errors and improving optical efficiency. Moreover, the coincidence of the central axis projection not only optimizes light energy utilization but also creates a compact axial layout space.

[0099] Furthermore, the composite curved surface optical characteristics of the mirror 1 can be fully inherited and optimized in the inner lens 4 and the outer lens 5, ensuring precise control of light in both horizontal and vertical dimensions; the special thickness gradient characteristics of the inner lens 4 complement the elliptical-parabolic composite curved surface of the mirror 1, jointly correcting astigmatism and field curvature problems; the moderate shortening of the outer lens unit 40 achieves optical trimming within the framework of central axis alignment, which not only meets the regulatory requirements for light patterns but also forms unique visual characteristics.

[0100] Furthermore, the coincidence of the projections of the first centerline L1, the second centerline L2, and the third centerline L3 provides an intuitive alignment reference for the assembly process, improving assembly accuracy and reducing the adverse effects of tolerance accumulation. In particular, centerline alignment does not increase manufacturing costs; instead, it reduces the manufacturing cost of the headlights provided in this embodiment by simplifying positioning tooling and inspection processes. Simultaneously, the coincidence of centerline projections effectively disperses mechanical stress, keeping the optical axis offset under vibration conditions within a small angular range.

[0101] like Figure 2As shown, in a specific embodiment of this invention, the top of the inner lens unit 30 is flush with the top of the outer lens unit 40, and the top of the reflector unit 20 is higher than the top of the inner lens unit 30.

[0102] The top of the inner lens unit 30 is flush with the top of the outer lens unit 40, allowing the light modulated by the inner lens 4 to smoothly transition to the outer lens 5, reducing light energy loss and improving the edge sharpness of the emitted light pattern. The arrangement where the top of the reflecting mirror unit 20 is higher than the top of the inner lens unit 30 provides ample space for the reflected light path, allowing the composite surface of the reflecting mirror 1 to fully utilize its optical characteristics and increase the effective reflective area.

[0103] Furthermore, the flush relationship between the top of the inner lens unit 30 and the top of the outer lens unit 40 ensures a seamless connection of the optical processing chain, thus avoiding light diffraction problems to a certain extent. In particular, the raised design of the top of the reflector unit 20 cleverly utilizes the space above the headlight, allowing the reflector 1 to adopt a larger radius of curvature. This not only increases the high beam illumination distance but also improves the uniformity of light intensity in the central area.

[0104] Furthermore, the flush top of the inner lens unit 30 with the top of the outer lens unit 40 simplifies the design of the front sealing structure and reduces the complexity of waterproofing; while the independent height setting of the reflector unit 20 provides ample space for its connection mechanism and heat dissipation channel. The elevated layout of the reflector unit 20 promotes natural air convection, which can reduce the operating temperature of critical components.

[0105] Please continue to combine Figure 6 , Figure 6 This is a light pattern diagram corresponding to the vehicle headlights provided in an embodiment of this application. For example... Figure 6 As shown in the figure, the spatial distribution of light intensity is presented in a two-dimensional coordinate system. The horizontal and vertical axes construct the planar dimensions for light intensity measurement. Different contour lines are contour lines with equal light intensity, and their density reflects the light intensity gradient. The contour lines are dense in the central area, corresponding to the main light-emitting area of ​​the light pattern. The light intensity gradually decreases as the contour lines extend outward.

[0106] The vehicle light provided in this embodiment also includes a circuit board assembly; wherein the light source 2 is disposed on the circuit board assembly. It is understood that the circuit board assembly may include a circuit board and electronic components disposed on the circuit board, and the light source 2 is disposed on the circuit board.

[0107] Furthermore, the vehicle light provided in this embodiment also includes a radiator, which is disposed below the circuit board assembly and abuts against the circuit board assembly; wherein, the baffle 3 and the radiator are an integral structure. That is to say, the baffle 3 can be integrally formed on the radiator body by, for example, injection molding.

[0108] Among them, the baffle 3, as an extension of the heat sink, not only undertakes optical control functions but also becomes a key component of the heat conduction path, increasing the heat dissipation area while reducing the number of parts. The heat generated by the light source 2 is directly transferred to the heat sink below through the circuit board assembly, and the integrated molding design of the baffle 3 and the heat sink further shortens the heat conduction path, enabling rapid reduction of the operating temperature of critical components.

[0109] Furthermore, the one-piece molded baffle 3 and the heat sink eliminate connection gaps, which not only improves the overall structural rigidity and reduces displacement under vibration conditions, but also avoids connection stress problems caused by differences in the thermal expansion coefficients of materials to a certain extent. In particular, as the upper extension of the heat sink, the baffle 3's special position precisely enhances the heat dissipation of the key area of ​​the light source 2. This design allows the junction temperature peak of the light source 2 to decrease, extending the service life of the light source 2.

[0110] Furthermore, the baffle 3 and the radiator are formed in one piece by die casting or precision injection molding, which not only simplifies the production process but also shortens the assembly time and improves the dimensional consistency between components.

[0111] Furthermore, the direct contact design between the heat sink and the circuit board assembly creates an efficient thermal path from the light source 2 to the external environment. This ensures excellent optical performance of the headlights while meeting the reliability requirements of modern automotive electronics for high-power-density lighting systems, thus improving the operational stability of the headlights.

[0112] It should be noted that multiple reflectors 1 can be equipped with one heat sink, and a baffle 3 can be integrally formed on the heat sink. One baffle 3 can block light from multiple reflectors 1. Of course, multiple reflectors 1 can also be equipped with multiple heat sinks, each with an integrally formed baffle 3. In this case, multiple baffles 3 can be connected together by welding or other methods. The structure of the heat sink will not be described in detail here.

[0113] This embodiment also provides a vehicle, including a body and the aforementioned headlights, with the headlights mounted on the body. The headlights should also include a lamp holder and / or lamp cover connected to the body; however, the structure of the headlights is not specifically limited here. Generally, to improve the overall assembly efficiency of the vehicle and to facilitate later maintenance of the headlights, a detachable connection method is used between the headlights and the body, such as through threaded fasteners like screws or clips. The connection method between the headlights and the body is not specifically limited here.

[0114] It should be noted that the vehicle provided in this embodiment should also include other modules or components that enable the vehicle to operate normally. Here, these other modules or components will not be described one by one.

[0115] The vehicle provided in this embodiment uses the aforementioned headlights, resulting in lower manufacturing costs and better performance.

[0116] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
