[0002] With the continuous development of the automotive industry, lens modules have become the mainstream solution for headlights and are being used more and more frequently in automobiles. However, current lens modules suffer from unreasonable layouts. Utility Model Content
[0003] This application provides a bi-xenon lens module, a headlight, and a vehicle to improve the problem of unreasonable lens module layout.
[0004] According to one aspect of this application, a dual-beam lens module is provided, including a light pattern baffle and a light-emitting assembly. The light pattern baffle has a first side and a second side opposite to each other along a first direction. The light-emitting assembly includes a first component and a second component. The first component includes a first light source, a first transmission surface, and a first reflection surface. Light emitted from the first light source passes sequentially through the first transmission surface and the first reflection surface before propagating to the first side. The second component includes a second light source, a second transmission surface, and a second reflection surface. Light emitted from the second light source passes sequentially through the second transmission surface and the second reflection surface before propagating to the second side. The light-emitting assembly and the light pattern baffle are arranged sequentially along a second direction, and the first component and the second component are arranged sequentially along the first direction, which intersects with the first direction. The optical axis direction of the first transmission surface is different from that of the second transmission surface.
[0005] In some embodiments, the optical axis direction of the first transmission surface is opposite to that of the second transmission surface.
[0006] In some embodiments, the optical axis direction of the first transmission surface is set at an angle to the optical axis direction of the second transmission surface.
[0007] In some embodiments, the first light source, the first transmissive surface, and the first reflective surface are arranged sequentially along the first direction, with the first light source located on the side of the first transmissive surface facing away from the light pattern baffle; the second light source, the second transmissive surface, and the second reflective surface are arranged sequentially along the first direction, with the second light source located on the side of the second transmissive surface facing away from the light pattern baffle.
[0008] In some embodiments, the light-emitting component includes a first lens and a second lens; a first transmission surface and a first reflection surface are disposed on the first lens, and a first light source is disposed on the side of the first transmission surface opposite to the first reflection surface; a second transmission surface and a second reflection surface are disposed on the second lens, and a second light source is disposed on the side of the second transmission surface opposite to the second reflection surface.
[0009] In some embodiments, the first lens and the second lens are an integral structure.
[0010] In some embodiments, the dual-lens module further includes a heat dissipation assembly, which includes a first heat dissipation section and a second heat dissipation section, the first heat dissipation section and the second heat dissipation section being located on opposite sides of the light-emitting assembly along the first direction.
[0011] In some embodiments, the heat dissipation assembly further includes a connecting portion, which connects the first heat dissipation portion and the second heat dissipation portion to its two ends along the first direction, respectively; the first heat dissipation portion, the connecting portion, and the second heat dissipation portion are an integral structure.
[0012] According to another aspect of this application, a vehicle lamp is provided, including a bi-xenon lens module as described above.
[0013] According to another aspect of this application, a vehicle is provided, including the aforementioned vehicle lights.
[0014] The dual-beam lens module of this application embodiment includes a light pattern baffle and a light-emitting component. The light-emitting component includes a first component and a second component. The first component includes a first light source, a first transmission surface, and a first reflection surface. Light emitted from the first light source passes sequentially through the first transmission surface and the first reflection surface before propagating to a first side of the light pattern baffle along a first direction. The second component includes a second light source, a second transmission surface, and a second reflection surface. Light emitted from the second light source passes sequentially through the second transmission surface and the second reflection surface before propagating to a second side of the light pattern baffle along the first direction. This effectively separates the two light patterns. Furthermore, the arrangement direction of the light pattern baffle and the light-emitting component intersects with the arrangement direction of the first component and the second component, and the optical axis direction of the first transmission surface is different from that of the second transmission surface. This ensures that the light-emitting path has components along at least two intersecting directions, reducing the overall depth space occupied, thus making the layout of the dual-beam lens module more reasonable. Moreover, since the first component and the second component are dispersed along the first direction, they can dissipate heat independently, thereby improving the heat dissipation effect.

[0032] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0033] In the following description, when referring to the accompanying drawings, the same numbers in different drawings denote the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0034] In related technologies, the dual-beam module sets the high beam and low beam on the same lamp panel, and separates the high beam and low beam by a light pattern baffle. Other related accessories, such as heat sinks, are arranged on the back of the lamp panel, which makes the overall lamp width larger and is not conducive to the overall lamp arrangement.
[0035] To address the aforementioned issues, this application provides a dual-beam lens module. By adjusting the arrangement of the light pattern baffle and the light-emitting component, the two light patterns are separated, and the light-emitting path has components along at least two intersecting directions, thereby reducing the overall depth space occupied. In other words, the layout of the dual-beam lens module is more reasonable.
[0036] See Figure 1 In some embodiments, the dual-beam lens module 1 includes a light pattern baffle 10 and a light-emitting assembly 20. The light-emitting assembly 20 is used to emit the desired light, and the light pattern baffle 10 is used to separate the different lights emitted by the light-emitting assembly 20, so that different types of light are obtained on both sides of the light pattern baffle 10, for example, near beam and far beam are obtained on both sides of the light pattern baffle 10 respectively.
[0037] Combined Figure 2 and Figure 3 The light pattern baffle 10 has a first side 11 and a second side 12 opposite to each other along a first direction X. The material of the light pattern baffle 10 is, for example, 304 stainless steel (SUS304). The surface of the light pattern baffle 10 can be aluminum-plated or non-aluminum-plated to improve reflectivity, thereby improving the overall lamp efficiency.
[0038] The light-emitting component 20 and the light-pattern baffle 10 are arranged sequentially along the second direction Y, which intersects the first direction X, for example, perpendicularly or at an acute angle. The light-emitting component 20 includes a first component 21 and a second component 22, which are arranged sequentially along the first direction X. In this way, the arrangement direction of the light-pattern baffle 10 and the light-emitting component 20 intersects with the arrangement direction of the first component 21 and the second component 22, making the space occupied in either arrangement direction relatively small.
[0039] Combined Figure 4 and Figure 5 The first component 21 includes a first light source 211, a first transmissive surface 2121, and a first reflective surface 2122. The first light source 211 is, for example, a light-emitting diode (LED). Light emitted from the first light source 211 passes sequentially through the first transmissive surface 2121 and the first reflective surface 2122 before propagating to the first side 11. The second component 22 includes a second light source 221, a second transmissive surface 2221, and a second reflective surface 2222. The second light source 221 is, for example, a light-emitting diode (LED). Light emitted from the second light source 221 passes sequentially through the second transmissive surface 2221 and the second reflective surface 2222 before propagating to the second side 12. The type of the first light source 211 may be the same as or different from the type of the second light source 221. The shape and size of the first transmissive surface 2121 may be the same as or different from the shape and size of the second transmissive surface 2221. The shape and size of the first reflective surface 2122 may be the same as or different from the shape and size of the second reflective surface 2222. The light from the first side 11 is either reflected by the light pattern baffle 10 or emitted directly without being reflected by the light pattern baffle 10. The light from the second side 12 is either reflected by the light pattern baffle 10 or emitted directly without being reflected by the light pattern baffle 10.
[0040] Furthermore, the optical axis direction of the first transmission surface 2121 is different from that of the second transmission surface 2221. Thus, the two light patterns are separated by the light pattern baffle 10, and each light pattern's output path has components along at least two intersecting directions, reducing the overall depth space occupied, making the layout of the dual-beam lens module 1 more rational. Moreover, since the first component 21 and the second component 22 are dispersed along the first direction X, they can dissipate heat independently, thereby improving the heat dissipation effect.
[0041] Optionally, the first reflecting surface 2122 is a total reflection surface, thereby improving the light output efficiency.
[0042] Optionally, the second reflecting surface 2222 is a total reflection surface, thereby improving the light extraction efficiency.
[0043] Optionally, the first component 21 further includes a first lamp panel 213, on which the first light source 211 is mounted. The second component 22 further includes a second lamp panel 223, on which the second light source 221 is mounted. Thus, the first lamp panel 213 provides a mounting reference for the first light source 211, and the second lamp panel 223 provides a mounting reference for the second light source 221.
[0044] Optionally, the first lamp panel 213 and the second lamp panel 223 are spaced apart along the first direction X. Further, the first lamp panel 213 and the second lamp panel 223 are parallel to each other, or there is an angle between them, such as an acute angle, a right angle, or an obtuse angle. This reduces the space occupied by the light-emitting assembly 20 along the second direction Y.
[0045] In some embodiments, the optical axis direction of the first transmission surface 2121 is opposite to that of the second transmission surface 2221. Optionally, the optical axes of the first transmission surface 2121 and the second transmission surface 2221 are parallel and offset from each other. This reduces the depth space occupied by the light-emitting component 20 while allowing for certain errors in the processing and installation of the light-emitting component 20, thereby improving efficiency. Optionally, the optical axes of the first transmission surface 2121 and the second transmission surface 2221 are located on the same straight line, which further reduces the depth space occupied by the light-emitting component 20.
[0046] In some embodiments, the optical axis of the first transmission surface 2121 is set at an angle to the optical axis of the second transmission surface 2221. For example, the angle between the optical axis of the first transmission surface 2121 and the optical axis of the second transmission surface 2221 is 30°, 45°, or 60°. This reduces the depth space occupied by the light-emitting component 20 while making its structural design more flexible.
[0047] In some embodiments, a first light source 211, a first transmissive surface 2121, and a first reflective surface 2122 are arranged sequentially along the first direction X, with the first light source 211 located on the side of the first transmissive surface 2121 facing away from the light-pattern baffle 10. A second light source 221, a second transmissive surface 2221, and a second reflective surface 2222 are arranged sequentially along the first direction X, with the second light source 221 located on the side of the second transmissive surface 2221 facing away from the light-pattern baffle 10. This allows for a more substantial reduction in the space occupied by the light-emitting assembly 20 along the second direction Y.
[0048] Optionally, the center of the first light source 211, the center of the first transmission surface 2121, and the center of the first reflection surface 2122 are located on the same virtual straight line, thereby further reducing the space occupied by the first component 21 along the second direction Y.
[0049] Optionally, the virtual straight line containing the center of the first light source 211, the center of the first transmission surface 2121, and the center of the first reflection surface 2122 extends along the first direction X, thereby further reducing the space occupied by the first component 21 along the second direction Y.
[0050] Optionally, the center of the second light source 221, the center of the second transmission surface 2221, and the center of the second reflection surface 2222 are located on the same virtual straight line, thereby further reducing the space occupied by the second component 22 along the second direction Y.
[0051] Optionally, the virtual straight line containing the center of the second light source 221, the center of the second transmission surface 2221, and the center of the second reflection surface 2222 extends along the second direction Y, thereby further reducing the space occupied by the second component 22 along the second direction Y.
[0052] See Figures 4-6 In some embodiments, the light-emitting assembly 20 includes a first lens 212 and a second lens 222. The first lens 212 and the second lens 222 may have the same or different shapes and materials. The first lens 212 and the second lens 222 may be separate structures or an integral structure. A first transmission surface 2121 and a first reflection surface 2122 are disposed on the first lens 212, and a first light source 211 is disposed on the side of the first transmission surface 2121 that is away from the first reflection surface 2122. A second transmission surface 2221 and a second reflection surface 2222 are disposed on the second lens 222, and a second light source 221 is disposed on the side of the second transmission surface 2221 that is away from the second reflection surface 2222. Thus, the light emitted by the first light source 211 is transmitted and reflected sequentially through the first lens 212 and propagates to the first side 11, for example, to obtain low beam; the light emitted by the second light source 221 is transmitted and reflected sequentially through the second lens 222 and propagates to the second side 12, for example, to obtain high beam.
[0053] In one exemplary embodiment, the first lens 212 and the second lens 222 are integrated into one structure. This makes the structure of the light-emitting assembly 20 more compact, reduces the space occupied by the light-emitting assembly 20, simplifies the overall structure of the light-emitting assembly 20, and reduces processing steps.
[0054] Optionally, the first lens 212 also has a first light-emitting surface 2123. The light emitted by the first light source 211 passes through the first transmission surface 2121 and the first reflection surface 2122 in sequence, and then exits through the first light-emitting surface 2123 and propagates to the first side 11.
[0055] Optionally, the second lens 222 also has a second light-emitting surface 2223. The light emitted by the second light source 221 passes through the second transmission surface 2221 and the second reflection surface 2222 in sequence, and then exits through the second light-emitting surface 2223 and propagates to the second side 12.
[0056] See Figure 1 , Figure 2 and Figure 7 In some embodiments, the dual-beam lens module 1 further includes a heat dissipation assembly 30, which includes a first heat dissipation part 31 and a second heat dissipation part 32. The first heat dissipation part 31 and the second heat dissipation part 32 are respectively located on opposite sides of the light-emitting assembly 20 along the first direction X. The first heat dissipation part 31 and the second heat dissipation part 32 are either separate structures or an integrated structure. Thus, because the first heat dissipation part 31 and the second heat dissipation part 32 are distributed on both sides along the first direction X, the overall space occupied by the dual-beam lens module 1 along the second direction Y is smaller. Simultaneously, because the first heat dissipation part 31 and the second heat dissipation part 32 are distributed on both sides along the first direction X, they can each independently dissipate heat from the first assembly 21 and the second assembly 22, resulting in higher heat dissipation efficiency for the first assembly 21 and the second assembly 22.
[0057] Optionally, the heat dissipation component 30 and the light emission component 20 are separate structures, that is, the heat dissipation component 30 is independent of the light emission component 20 and can be separated separately, thereby facilitating the overall structural layout.
[0058] Optionally, the heat dissipation assembly 30 further includes a connecting portion 33, which connects the first heat dissipation portion 31 and the second heat dissipation portion 32 at its two ends along the first direction X, respectively. Connecting the first heat dissipation portion 31 and the second heat dissipation portion 32 via the connecting portion 33 improves the stability of the overall structure. Furthermore, the first heat dissipation portion 31, the connecting portion 33, and the second heat dissipation portion 32 are integrated into a single structure. This further enhances the stability of the overall structure and improves heat dissipation performance.
[0059] Optionally, the first heat dissipation unit 31 includes a plurality of first heat dissipation fins 311, which are arranged sequentially along a third direction Z. The third direction Z, the first direction X, and the second direction Y intersect each other, for example, they are perpendicular to each other or the included angle is an acute angle. In this way, the heat dissipation efficiency can be improved.
[0060] Optionally, the forming process of the multiple first heat sinks 311 can be riveting, cold forging or die casting, depending on the material.
[0061] Optionally, the second heat dissipation unit 32 includes a plurality of second heat dissipation fins 321, which are arranged sequentially along a third direction Z. The third direction Z, the first direction X, and the second direction Y intersect each other, for example, they are perpendicular to each other or the included angle is an acute angle. In this way, the heat dissipation efficiency can be improved.
[0062] Optionally, the forming process of the multiple second heat sinks 321 can be riveting, cold forging or die casting, depending on the material.
[0063] In some embodiments, the dual-lens module 1 further includes an outer lens 40, which is made of, for example, plastic or glass. The outer lens 40, the light pattern baffle 10, and the light-emitting assembly 20 are arranged sequentially along the second direction Y. The light emitted by the first light source 211 passes sequentially through the first transmission surface 2121 and the first reflection surface 2122, then propagates to the first side 11, is reflected by the light pattern baffle 10, and is emitted through the outer lens 40, or it can be emitted directly through the outer lens 40 without being reflected by the light pattern baffle 10. The light emitted by the second light source 221 passes sequentially through the second transmission surface 2221 and the second reflection surface 2222, then propagates to the second side 12, is reflected by the light pattern baffle 10, and is emitted through the outer lens 40, or it can be emitted directly through the outer lens 40 without being reflected by the light pattern baffle 10.
[0064] In some embodiments, the dual-lens module 1 further includes a lens bracket 50, with an outer lens 40 mounted at one end of the lens bracket 50 along the second direction Y, thereby using the lens bracket 50 to support the outer lens 40.
[0065] Optionally, the outer lens 40 and the lens holder 50 are connected by a snap-fit mechanism, which facilitates assembly.
[0066] In some embodiments, the bi-xenon lens module 1 further includes an ablation plate 60, which is mounted within the lens bracket 50 and located on the side of the outer lens 40 facing the light-emitting assembly 20. It is understood that when the bi-xenon lens module 1 is used in automotive headlights, the strong focusing ability of the outer lens 40 may pose a risk of solar beam ablation. Therefore, this embodiment provides an ablation plate 60 in the solar beam focusing area, i.e., on the side of the outer lens 40 facing the light-emitting assembly 20, to achieve an ablation prevention effect. For example, a metal, such as aluminum, is provided in the solar beam focusing area to dissipate concentrated heat through the uniform heating of the metal, thereby mitigating the problem of solar beam ablation.
[0067] Optionally, the connection between the ablation plate 60 and the lens holder 50 is a snap-fit connection, which facilitates assembly.
[0068] Based on the same inventive concept, this application also provides a vehicle light, including a bi-xenon lens module as described in the above embodiments.
[0069] Based on the same inventive concept, this application also provides a vehicle, including the headlights as described in the above embodiments.
