[0001] Cross-references to related applications
[0002] This application claims the benefit of Chinese Patent Application No. 202510378241.8, filed on March 28, 2025, the contents of which are incorporated herein by reference. Technical Field
[0003] This application relates to the technical field of automotive lighting, specifically to a lighting module and a lighting lamp. Background Technology
[0004] In recent years, with the development trend of automotive intelligence and the continuous improvement of regulatory requirements, the field of automotive lighting has also made many corresponding adjustments and progress.
[0005] Existing headlight modules typically use an ellipsoidal or ellipsoidal reflector to converge light emitted from a light source positioned near the focal point of the ellipsoidal or ellipsoidal surface to a far focal point on the same surface. The far focal point of this ellipsoidal or ellipsoidal surface is then located at the focal point of a convex lens, thus forming an image of the light spot at the lens's focal point. However, this results in a large longitudinal dimension for the headlight module, failing to meet the requirements for flattened headlights and reduced space occupation. Summary of the Invention
[0006] The purpose of this application is to overcome the problem of large space occupation of existing vehicle lighting modules and to provide a vehicle lighting module with the advantages of small space occupation and easy use.
[0007] To achieve the above objectives, this application provides a vehicle headlight module, including a low beam module, a high beam module, and a light-emitting lens. The low beam module and the high beam module are located on the same side of the light-emitting lens and are arranged vertically. The low beam module includes a low beam source and a low beam bending component, and the high beam module includes a high beam source and a high beam bending component. The low beam bending component and the high beam bending component are arranged vertically between the low beam source and the high beam source. The light emitted from the low beam source and the high beam source is reflected by the low beam bending component and the high beam bending component, respectively, and then enters the light-emitting lens through the same light-incident surface of the light-emitting lens. The light then exits from the same light-emitting surface of the light-emitting lens and is projected to form the desired low beam pattern and high beam pattern, respectively.
[0008] In some embodiments, the low beam bending assembly includes a low beam reflecting structure and a low beam bending structure disposed vertically. The low beam reflecting structure is disposed adjacent to the low beam source so that the light emitted from the low beam source can be reflected by the low beam reflecting structure and reflected towards the low beam bending structure, and then reflected again by the low beam bending structure and directed towards the light-emitting lens.
[0009] The high beam bending component includes a high beam reflecting structure and a high beam bending structure arranged vertically. The high beam reflecting structure is positioned adjacent to the high beam light source so that the light emitted from the high beam light source can be reflected by the high beam reflecting structure and then reflected towards the high beam bending structure. After being reflected again by the high beam bending structure, the light is then directed towards the light-emitting lens.
[0010] In some embodiments, the low beam reflection structure includes a low beam reflecting surface, and the low beam bending structure includes a low beam bending reflecting surface. The low beam reflecting surface and the low beam bending reflecting surface are arranged one above the other. The light emitted from the low beam source is reflected by the low beam reflecting surface and then directed towards the low beam bending reflecting surface, and after being reflected by the low beam bending reflecting surface, it is directed towards the light-emitting lens.
[0011] In some embodiments, the low beam bending structure further includes a low beam bending entrance surface and a low beam bending exit surface. The light reflected by the low beam reflecting structure enters the low beam bending structure from the low beam bending entrance surface, and after being reflected by the low beam bending reflecting surface, it is directed to the light exiting lens from the low beam bending exit surface.
[0012] In some embodiments, the low beam cutoff line structure of the low beam module is located at the boundary of the low beam reflection structure near the low beam source.
[0013] In some embodiments, the low beam reflection structure and the low beam bending structure are integrated into one piece.
[0014] In some embodiments, the high beam reflecting structure includes a high beam reflecting surface, and the high beam bending structure includes a high beam bending reflecting surface. The high beam reflecting surface and the high beam bending reflecting surface are arranged one above the other. The light emitted from the high beam source is reflected by the high beam reflecting surface and then directed towards the high beam bending reflecting surface, and after being reflected by the high beam bending reflecting surface, it is directed towards the light-emitting lens.
[0015] In some embodiments, the high beam bending structure further includes a high beam bending light-inlet surface and a high beam bending light-outlet surface. The light reflected by the high beam reflecting structure enters the high beam bending structure from the high beam bending light-inlet surface, and after being reflected by the high beam bending light-reflecting surface, it is directed to the light-outlet lens from the high beam bending light-outlet surface.
[0016] In some embodiments, the high beam reflection structure and the high beam bending structure are integrated into one piece.
[0017] In some embodiments, the circuit board is also included, which is disposed between the light-emitting lens and the low beam module and the high beam module. The low beam module and the high beam module are disposed on one side of the circuit board, and a heat dissipation structure is disposed on the other side.
[0018] In some embodiments, the middle area of the circuit board is configured as an opening, and the emitted light from the low beam module and the high beam module is adapted to pass through the opening and be emitted by the light-emitting lens.
[0019] A second aspect of this application provides a vehicle light, including the aforementioned vehicle light module.
[0020] Through the above technical solution, the light emitted from the low beam and high beam sources of this application ultimately enters and exits from the same light-emitting surface of the light-emitting lens, eliminating the need to distinguish between the high beam and low beam light-emitting surfaces of the light-emitting lens. For the integrated high and low beam module, in low beam mode, the entire light-emitting lens can be illuminated, eliminating the need for additional cost and structural design for the high beam accompanying illumination effect in low beam mode (the high beam accompanying illumination effect refers to the effect that the lens corresponding to the high beam module can also be illuminated in low beam mode), and achieving a better appearance when the headlights are illuminated. Meanwhile, during the process of light emission from the low beam module and high beam module, the low beam bending component and high beam bending component can deflect the transmission optical paths of the low beam and high beam light. Specifically, the original light paths of the low beam module and high beam module in the front-rear direction are deflected to other directions by the low beam bending component and high beam bending component, shortening the transmission optical paths of the low beam and high beam light in the front-rear direction while realizing the emission of low beam and high beam light. The low beam bending component and high beam bending component effectively reduce the front-rear size of the headlight module and realize the flattening of the headlight module.

It should also be understood that terms defined in general dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and not as idealized or highly formalized, unless expressly defined herein.
[0032] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.
[0033] Referring to Figures 1 and 4, this application discloses a vehicle headlight module, including a low beam module 1, a high beam module 2, and a light-emitting lens 3. The low beam module 1 and the high beam module 2 are located on the same side of the light-emitting lens 3 and are arranged vertically. The low beam module 1 includes a low beam light source 4 and a low beam bending component 5. The high beam module 2 includes a high beam light source 6 and a high beam bending component 7. The low beam bending component 5 and the high beam bending component 7 are arranged vertically between the low beam light source 4 and the high beam light source 6. The light emitted from the low beam light source 4 and the high beam light source 6 is reflected by the low beam bending component 5 and the high beam bending component 7, respectively, and then enters the light-emitting lens 3 through the same light-incident surface of the light-emitting lens 3. The light is emitted from the same light-emitting surface of the light-emitting lens 3 and projected to form the desired low beam and high beam light patterns, respectively.
[0034] This application discloses a vehicle headlight module including a light-emitting lens 3. A low beam module 1 and a high beam module 2 are arranged vertically on one side of the light-incident surface of the light-emitting lens 3. Light emitted from the low beam source 4 and the high beam source 6 ultimately enters the same light-incident surface of the light-emitting lens 3 and exits from the same light-emitting surface. The light-emitting lens 3 can be illuminated in both low beam and high beam modes. This application does not require distinguishing between the high beam and low beam light-incident surfaces of the light-emitting lens 3. For an integrated high / low beam module, the entire light-emitting lens 3 can be illuminated in low beam mode, eliminating the need for additional cost and structural design for a simultaneous high beam illumination effect in low beam mode (the simultaneous high beam illumination effect refers to the effect that the lens corresponding to the high beam module 2 can also be illuminated in low beam mode), while still achieving a good headlight illumination appearance.
[0035] The high beam module 2 has multiple sets in the left and right directions.
[0036] The low beam module 1 also has multiple sets in the left and right directions.
[0037] In the vertical direction, a low beam bending component 5 and a high beam bending component 7 are provided between the low beam light source 4 and the high beam light source 6. The light emitted from the low beam light source 4 and the high beam light source 6 first shines on the low beam bending component 5 and the high beam bending component 7 respectively, and is reflected by the low beam bending component 5 and the high beam bending component 7 respectively and enters the same light incident surface of the light exiting lens 3.
[0038] In the process of emitting light from the low beam module 1 and the high beam module 2, the low beam bending component 5 and the high beam bending component 7 of the disclosed vehicle headlight module can deflect the transmission optical paths of the low beam and high beam light. Specifically, the original light paths of the low beam module 1 and the high beam module 2 in the front-rear direction are deflected to other directions by the low beam bending component 5 and the high beam bending component 7, which shortens the transmission optical paths of the low beam and high beam light in the front-rear direction and realizes the emission of low beam and high beam light. The low beam bending component 5 and the high beam bending component 7 effectively reduce the front-rear size of the vehicle headlight module and realize the flattening of the vehicle headlight module.
[0039] Example 1:
[0040] Referring to Figures 1 and 2, the low beam bending component 5 and the high beam bending component 7 are arranged in the vertical direction.
[0041] Referring to Figures 1 and 2, the low beam bending component 5 and the high beam bending component 7 can be set separately or as a single piece. The single-piece low beam bending component 5 and the high beam bending component 7 can reduce the vertical spacing between the low beam module 1 and the high beam module 2, thereby reducing the size of the headlight module.
[0042] Referring to Figures 1 and 4, the low beam bending assembly 5 includes a low beam reflecting structure 51 and a low beam bending structure 52 arranged vertically. The low beam reflecting structure 51 is positioned adjacent to the low beam source 4 so that the light emitted from the low beam source 4 can be reflected by the low beam reflecting structure 51 and then reflected towards the low beam bending structure 52. After being reflected again by the low beam bending structure 52, the light is emitted towards the light-emitting lens 3. For example, as shown in Figures 1 and 4, in the vertical direction, the low beam reflecting structure 51 is located above the low beam bending structure 52. The side of the low beam reflecting structure 51 facing the low beam source 4 forms a low beam reflecting surface 511, and the low beam bending structure 52 forms a low beam bending reflecting surface 521. The low beam bending reflecting surface 521 can be a total reflection surface. The light emitted from the low beam source 4 is reflected by the low beam reflecting surface 511 and then towards the low beam bending structure 52. After being reflected by the low beam bending reflecting surface 521, the light is emitted towards the light-emitting lens 3. Of course, the low beam reflector 51 can also be located below the low beam bending structure 52 (not shown in the figure), without affecting the transmission of light. In this embodiment, the low beam bending reflector 521 of the low beam bending structure 52 can deflect the low beam light path, deflecting the original front-to-back light path of the low beam module 1 upwards. At the same time, the low beam light source 4 and the low beam reflector 51 are positioned above the low beam bending structure 52, ultimately achieving the low beam function. The combined arrangement of the low beam reflector 51 and the low beam bending structure 52 effectively shortens the front-to-back dimensions of the headlight module, achieving a flattened headlight module.
[0043] Referring to Figures 1 and 4, the near-light reflector 511 is a curved surface, and the direction of light reflection is towards the near-light bending structure 52.
[0044] Referring to Figures 1 and 4, the low beam cutoff line structure of the low beam module 1 is located at the boundary of the low beam reflection structure 51 near the low beam source 4.
[0045] Referring to Figures 1 and 4, the near beam bending structure 52 is a transparent part with an approximately triangular cross-section. The near beam bending structure 52 includes a near beam bending incident surface 522, a near beam bending reflective surface 521, and a near beam bending exit surface 523. The near beam bending incident surface 522 is one side of the near beam bending structure 52 facing the near beam reflective structure 51, and the near beam bending exit surface 523 is one side of the near beam bending structure 52 facing the light-emitting lens 3. The near beam bending reflective surface 521 is one side connecting the near beam bending incident surface 522 and the near beam bending exit surface 523. The light emitted from the near beam source 4 is collimated by the near beam reflective surface 511 and then shines on the near beam bending incident surface 522 and enters the near beam bending structure 52. After being reflected by the near beam bending reflective surface 521, it is emitted from the near beam bending exit surface 523 and shines on the light-emitting lens 3.
[0046] Referring to Figures 1 and 4, the angle between the cross section of the longitudinal section of the near beam bending reflector 521 and the optical axis of the light-emitting lens 3 is within the range of 45°±15°. By controlling the angle, the projection position of the near beam pattern can be adjusted. If the angle is less than 45°, the projection position of the near beam pattern moves downward; if the angle is greater than 45°, the projection position of the near beam pattern moves upward.
[0047] Referring to Figures 1 and 4, the near beam bending light-incident surface 522 and / or the near beam bending reflective surface 521 and / or the near beam bending light-outcident surface 523 can be a plane, a curved surface, or a focusing surface.
[0048] For example, the low beam bending reflector 521 is a focusing surface, preferably focusing the light in a horizontal direction. Its focal point is set at or within 10 mm of the low beam source 4, or on or within 10 mm of the low beam reflector 51, which can better control the convergence and diffusion of the low beam.
[0049] For example, the low beam bending light-in-the-light surface 522 is the focusing surface, and its focal point is set at or within 10 mm of the low beam light source 4, or at or within 10 mm of the low beam reflector structure 51.
[0050] For example, the near beam bending light-emitting surface 523 is the focusing surface, and its focal point is set at or within 10 mm of the near beam source virtual image 4', or at or within 10 mm of the near beam reflection structure virtual image 51'.
[0051] It should be noted that, referring to Figure 4, the position of the virtual image in the low beam portion is determined by the low beam bending and reflecting surface 521 of the low beam bending structure 52. The low beam source 4 and the virtual image 4' of the low beam source are symmetrical about the low beam bending and reflecting surface 521, and the low beam reflecting structure 51 and the virtual image 51' of the low beam reflecting structure are also symmetrical about the low beam bending and reflecting surface 521.
[0052] Referring to Figures 1 and 4, the high beam bending assembly 7 includes a high beam reflecting structure 71 and a high beam bending structure 72 arranged vertically. The high beam reflecting structure 71 is positioned adjacent to the high beam light source 6 so that the light emitted from the high beam light source 6 can be reflected by the high beam reflecting structure 71 and then reflected towards the high beam bending structure 72. After being reflected again by the high beam bending structure 72, the light then travels towards the light-emitting lens 3. For example, as shown in Figures 1 and 4, in the vertical direction, the high beam reflecting structure 71 is located below the high beam bending structure 72. The side of the high beam reflecting structure 71 facing the high beam light source 6 forms a high beam reflecting surface 711, and the high beam bending structure 72 forms a high beam bending reflecting surface 721. The high beam bending reflecting surface 721 can be a total reflection surface. The light emitted from the high beam light source 6 is reflected by the high beam reflecting surface 711 and then travels towards the high beam bending structure 72. After being reflected again by the high beam bending reflecting surface 721, the light then travels towards the light-emitting lens 3. Of course, the high beam reflector 71 can also be located above the high beam bending structure 72 (not shown in the figure) without affecting the transmission of light. In this embodiment, the high beam bending reflector 721 of the high beam bending structure 72 can deflect the high beam light path, deflecting the original front-to-back light path of the high beam module 2 downwards. At the same time, the high beam light source 6 and the high beam reflector 71 are located below the high beam bending structure 72, ultimately realizing the high beam function. The combined arrangement of the high beam reflector 71 and the high beam bending structure 72 effectively shortens the front-to-back dimensions of the headlight module, achieving a flattened headlight module.
[0053] Referring to Figures 1 and 4, the high beam reflector 711 is a curved surface, and the direction of light reflection is towards the high beam bending structure 72.
[0054] Referring to Figures 1 and 4, the high beam bending structure 72 is a transparent part with an approximately triangular cross-section. The high beam bending structure 72 includes a high beam bending light-incident surface 722, a high beam bending reflective surface 721, and a high beam bending light-outcrystal surface 723. The high beam bending light-incident surface 722 is one side of the high beam bending structure 72 facing the high beam reflective structure 71, and the high beam bending light-outcrystal surface 723 is one side of the high beam bending structure 72 facing the light-outcrystal lens 3. The high beam bending reflective surface 721 is one side connecting the high beam bending light-incident surface 722 and the high beam bending light-outcrystal surface 723. The light emitted from the high beam source 6 is collimated by the high beam reflective surface 711 and then shines on the high beam bending light-incident surface 722 and enters the high beam bending structure 72. After being reflected by the high beam bending reflective surface 721, it is emitted from the high beam bending light-outcrystal surface 723 and shines on the light-outcrystal lens 3.
[0055] Referring to Figures 1 and 4, the angle between the cross section of the longitudinal section of the high beam bending reflector 721 and the optical axis of the light-emitting lens 3 is within the range of 45°±15°. By controlling the angle, the projection position of the high beam pattern can be adjusted. If the angle is less than 45°, the projection position of the high beam pattern moves downward; if the angle is greater than 45°, the projection position of the high beam pattern moves upward.
[0056] Referring to Figures 1 and 4, the high beam bending light-increasing surface 722 and / or the high beam bending reflective surface 721 and / or the high beam bending light-exiting surface 723 can be a plane, a curved surface, or a focusing surface.
[0057] For example, the high beam bending reflector 721 is a focusing surface, preferably focusing the light in a horizontal direction. Its focal point is set at or within 10 mm of the high beam source 6, or on or within 10 mm of the high beam reflector structure 71, which can better control the convergence and diffusion of the high beam light.
[0058] For example, the high beam bending light-in-the-light surface 722 is the focusing surface, and its focal point is set at or within 10 mm of the high beam light source 6, or at or within 10 mm of the high beam reflecting structure 71.
[0059] For example, the high beam bending light-emitting surface 723 is the focusing surface, and its focal point is set at or within 10 mm of the near beam source virtual image 6', or at or within 10 mm of the high beam reflection structure virtual image 71'.
[0060] It should be noted that, referring to Figure 4, the position of the virtual image of the high beam is determined by the high beam bending reflection surface 721 of the high beam bending structure 72. The virtual images 6' of the high beam source 6 and the low beam source are symmetrical about the high beam bending reflection surface 721, and the virtual images 71' of the high beam reflection structure 71 are also symmetrical about the high beam bending reflection surface 721.
[0061] Referring to Figures 1 and 4, the light-emitting lens 3 is a single piece. The focal point of the light-emitting lens 3 is located at or within 10 mm of the near light source virtual image 4' and / or at or within 10 mm of the near light source virtual image 6'. The positions of the near light source virtual image 4' and the near light source virtual image 6' coincide or are close to each other.
[0062] Referring to Figures 1 and 3, the headlight module disclosed in this embodiment also includes a circuit board 8. The circuit board 8 is disposed between the light-emitting lens 3 and the low beam module 1 and the high beam module 2. The low beam module 1 and the high beam module 2 are disposed on one side of the circuit board 8, and a heat dissipation structure 81 is disposed on the other side. Specifically, the circuit board 8 is located on the side of the low beam module 1 and the high beam module 2 facing the light-emitting lens 3. To prevent the light emitted towards the light-emitting lens 3 from being blocked by the circuit board 8, the middle area of the circuit board 8 is set as an opening, so that the light emitted from the low beam module 1 and the high beam module 2 can pass through the opening and shine towards the light-emitting lens 3. Furthermore, to accommodate both the high beam light source 6 and the low beam light source 4 on the same circuit board 8, while the middle area of the circuit board 8 is designed as an opening, at least one side of the circuit board 8 remains connected. For example, as shown in Figure 3, the circuit board 8 has a C-shaped structure. Both the low beam light source 4 and the high beam light source 6 are located on the same side of the same circuit board 8, sharing the same circuit board 8, thus reducing costs. Moreover, the low beam light source 4 and the high beam light source 6 are spaced vertically on the circuit board 8, providing sufficient space to arrange the heat dissipation structure 81 on the other side of the circuit board 8, improving heat dissipation. The circuit board 8 and the heat dissipation structure 81 are positioned between the light-emitting lens 3 and the low beam module 1 and high beam module 2 without obstructing the low beam and high beam light, reducing the front-rear dimensions of the headlight module and facilitating its flattening. Furthermore, the heat dissipation structure 81 is a heat sink, and the low beam module 1 and high beam module 2 use the same heat sink for heat dissipation, reducing the number of parts, lowering costs, and saving space.
[0063] Through the above technical solution, the light path of the original front and rear parts of the low beam module 1 of this application is deflected to the vertical direction by the setting of the low beam bending structure 52, and the low beam is finally emitted by the setting of the low beam reflection structure 51. The combination of the low beam reflection structure 51 and the low beam bending structure 52 effectively shortens the front and rear size of the headlight module and realizes the flattening of the headlight module.
[0064] The original light paths of the front and rear parts of the high beam module 2 are partially deflected to the vertical direction by the setting of the high beam bending structure 72. At the same time, the high beam is finally emitted by the setting of the high beam reflection structure 71. The combination of the high beam reflection structure 71 and the high beam bending structure 72 effectively shortens the front and rear dimensions of the headlight module and realizes the flattening of the headlight module.
[0065] Meanwhile, the high beam module 2 and low beam module 1 arranged vertically share a light-incident surface of the light-emitting lens 3, so there is no need to distinguish between the high beam and low beam light-incident surfaces of the light-emitting lens 3, which can achieve the effect of simultaneous lighting and good lighting appearance.
[0066] In addition, the low beam light source 4 and the high beam light source 6 are set on the same side of the same circuit board 8, which reduces the cost of setting up the circuit board 8 and facilitates the arrangement of the heat dissipation structure 81, thereby improving the heat dissipation efficiency. The circuit board 8 and the heat dissipation structure 81 are set between the light-emitting lens 3 and the low beam module 1 and the high beam module 2, which further reduces the front and rear dimensions of the headlight module and realizes the flattening of the headlight module.
[0067] On the other hand, this application also discloses a vehicle light, including the aforementioned vehicle light module.
[0068] Example 2:
[0069] Referring to Figures 5 and 6, this embodiment discloses a vehicle headlight module based on Embodiment 1. The difference from Embodiment 1 is that the low beam reflector structure 51 and the low beam bending structure 52 are integrated into one piece. The low beam reflector surface 511 is connected to the low beam bending light-incident surface 522. The surface of the low beam reflector surface 511 can be aluminum-plated. The light emitted from the low beam source 4 is directly incident on the low beam bending reflector surface 521 from the low beam reflector surface 511. After being reflected by the low beam bending reflector surface 521, it is emitted from the low beam bending light-out surface 523 and transmitted to the light-incident surface of the light-out lens 3. The integrated design of the low beam reflector structure 51 and the low beam bending structure 52 reduces the distance between them, making the headlight module more compact vertically and smaller in size. It also reduces the number of parts and makes assembly more convenient.
[0070] The high beam reflector 61 and the high beam bending structure 62 are integrated into one unit. The high beam reflector 611 is connected to the high beam bending light-incident surface 722. The surface of the high beam reflector 711 can be plated with aluminum. The light emitted from the high beam source 6 is directly incident on the high beam bending reflector 721 by the high beam reflector 711. After being reflected by the high beam bending reflector 721, it is emitted by the high beam bending light-out surface 723 and transmitted to the light-incident surface of the light-out lens 3. The integrated design of the high beam reflector 71 and the high beam bending structure 72 reduces the distance between them, making the headlight module more compact and smaller in size.
