Description

Technical Field

[0001] This application relates to the field of automotive lighting technology, and more specifically, to a vehicle lamp module and a vehicle lamp. Background Technology

[0002] With the continuous advancement of industrialization, automobiles have become an indispensable means of transportation in people's daily lives. As an important component of the automotive lighting system, headlights play a crucial role in improving vehicle performance and safety. At the same time, consumer demand for automotive lighting functions is constantly growing. The core functions of automotive front combination lights include high beam and low beam illumination, and PES (Poly-Ellipsoid System) modules are one of the key technologies for achieving these functions.

[0003] PES modules primarily rely on ellipsoidal reflectors as primary optical elements and lenses as secondary optical elements to achieve high and low beam illumination. However, traditional PES modules typically only support a single function, such as providing only low or high beam illumination. This design requires the use of two modules simultaneously to meet the full functional requirements of the front combination light, resulting in a significant increase in module cost, structural complexity, and installation and commissioning time costs.

[0004] To address these issues, some PES modules have developed integrated high and low beam solutions by introducing mechanical solenoid valves. However, this design also has drawbacks, such as the high cost and poor durability of solenoid valves. Furthermore, these modules typically require large lens apertures, resulting in limited design options and difficulty in meeting aesthetic requirements. Utility Model Content

The low beam module includes a low beam light source and a low beam primary optical element, a low beam III zone forming structure, and a low beam light emitting element arranged sequentially along the optical path. Part of the light emitted from the low beam light source is converged by the low beam primary optical element and transmitted to the low beam III zone forming structure.

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. It should be noted that, unless otherwise specified, the various features in the embodiments of this application can be combined with each other, and the combined embodiments are still within the protection scope of this application.

[0039] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, if an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0040] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0041] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0042] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0043] One aspect of this application provides a vehicle headlight module designed to meet market demand for narrow-aperture headlight designs while improving nighttime driving safety. For example... Figures 1 to 5 As shown, the headlight module includes a low beam module and a high beam module arranged laterally. Its structural layout significantly reduces the size of the headlight opening in the vehicle's height direction, making it more suitable for the streamlined and compact exterior design requirements of modern automobiles. Through this layout, the headlights achieve functionality while also satisfying consumers' pursuit of aesthetics and personalization.

[0044] like Figures 1 to 3 As shown, the low beam module includes a low beam source 10, a primary low beam optical element, a low beam zone III forming structure 11, and a low beam output element 12, which are arranged sequentially along the optical path. A portion of the light generated by the low beam source 10 is first converged by the primary low beam optical element and then transmitted to the low beam zone III forming structure 11. After being reflected by the reflective surface of the low beam zone III forming structure 11, it is emitted through the low beam output element 12, forming a low beam zone III light pattern that meets regulatory requirements. The low beam zone III light pattern satisfies the requirements for light pattern illumination intensity distribution and regulations, providing sufficient illumination while minimizing interference with other road users.

[0045] like Figure 4 As shown, to further optimize the performance of the low beam pattern, a first dimming structure 111 is designed on the reflective surface of the low beam III formation structure 11. This dimming structure reduces the brightness of other local areas within the low beam pattern by precisely adjusting the reflection angle of some light rays. This design enables brightness control of different areas within the low beam pattern, effectively reducing glare for drivers or pedestrians and significantly improving nighttime driving safety.

[0046] Specifically, the first dimming structure 111 includes one or more of the following: curved dimming structure, planar dimming structure, convex dot dimming structure, striped dimming structure, and patterned dimming structure. Their combination can be specifically designed according to the desired lighting effect to precisely control the low beam pattern. The regulatory measurement points in the low beam pattern can be processed using different forms of the first dimming structure 111 to ensure the light pattern meets regulatory requirements. For example, in... Figure 15 The light pattern area corresponding to the B50L measuring point is identified, and the corresponding first dimming structure 111 is designed as multiple convex dimming structures. These convex dimming structures reduce the brightness of the light pattern area corresponding to the B50L measuring point by scattering light in all directions. Thus, within the final low-beam light pattern, a locally lower brightness area will form at the B50L measuring point, satisfying the illuminance limit for the B50L measuring point in Table 1. A similar method can be used to adjust the brightness values ​​of other measuring points requiring reduced brightness, such as the HV measuring point, to the range required by regulations. Furthermore, striped dimming structures and patterned dimming structures also reduce the brightness of local areas within the low-beam light pattern by scattering light in all directions, while planar dimming structures reduce the brightness of local areas within the low-beam light pattern because they do not converge light.

[0047] Optionally, such as Figure 4As shown, a second dimming structure 112 is also provided on the upper side of the reflective surface of structure 11 in the low beam III zone, near the low beam light source 10. The second dimming structure 112 is a raised structure, and its position and size can be rationally designed according to the desired lighting effect to block the corresponding light rays so that the corresponding light pattern area meets regulatory requirements. For example, in... Figure 15 Find the light pattern area corresponding to the 50L measurement point, and set the size-matching protrusion structure on the reflective surface of the near beam III forming structure 11 close to the upper side of the near beam light source 10, so that the protrusion structure blocks the light illuminating this area, thereby reducing the brightness of the light pattern area corresponding to the 50L measurement point, so as to meet the illuminance limit value of the 50L measurement point in Table 1.

[0048] Optionally, such as Figure 5 and Figure 7 As shown, the primary optical element for the low beam is the low beam reflector 13. A portion of the light emitted from the low beam source 10 is converged and reflected by the low beam reflector 13, ultimately incident on the low beam emitter 12, where it is converged and emitted to form the main low beam pattern. Thus, the low beam III zone pattern and the main low beam pattern are superimposed to form a complete low beam pattern, achieving high brightness, high uniformity, and a wide range of low beam illumination.

[0049] Furthermore, such as Figure 5 and Figure 6 As shown, the primary optical element for low beam also includes a low beam III zone reflector 15 disposed on the low beam reflector 13. Part of the light emitted from the low beam source 10 passes through the low beam III zone reflector 15 and the low beam III zone forming structure 11 in sequence for convergence and adjustment, and finally enters the low beam output element 12, which converges and outputs to form the low beam III zone light pattern.

[0050] The low beam source 10 can be a small, high-brightness, and long-life light source such as an LED or laser, resulting in a compact and long-lasting headlight module. The low beam III zone reflector 15 can be made of various forms and materials. For example, the reflective surface of the low beam III zone reflector 15 can be designed as an ellipsoid, freeform surface, etc., to adapt to different light pattern requirements. Its material is typically a high-reflectivity aluminum alloy or a high-temperature resistant plastic, coated with a metal film or nano-coating to further improve reflection efficiency. The low beam output element 12 can be a lens or mirror, further optimizing the emitted low beam pattern through optical refraction or reflection.

[0051] Optionally, such as Figure 5 and Figure 8As shown, the high beam module includes a high beam source 20 and a high beam reflector 21 and a high beam emitter 22 arranged sequentially along the optical path. The light emitted from the high beam source 20 is converged and adjusted by the high beam reflector 21, and finally incident on the high beam emitter 22, where it is converged and emitted to form a uniform, high-brightness, and directionally concentrated high beam pattern. The structural design and technical performance of the high beam source 20 are similar to those of the low beam source 10; the structural design and technical performance of the high beam reflector 21 are similar to those of the low beam reflector 13; and the structural design and technical performance of the high beam emitter 22 are similar to those of the low beam emitter 12. These details will not be elaborated further here.

[0052] Optionally, such as Figure 5 As shown, the high beam reflector 21 and the low beam reflector 13 are arranged laterally and integrally formed to constitute an integrated reflector element. Simultaneously, the low beam emitting element 12 and the high beam emitting element 22 are also arranged laterally and integrally formed to constitute an integrated emitting element. This integrated reflector and emitting element reduces assembly processes and errors between components, allowing for efficient light transmission during reflection and emission, ensuring consistent and reliable optical performance. Furthermore, the laterally arranged overall design gives the headlight a narrow and elongated opening, meeting the modern automotive requirements for a combination of aesthetics and functionality.

[0053] The low beam light source 10 and the high beam light source 20 can be distributed on different circuit boards 30 according to actual needs and connected by flexible printed circuit boards (FPCBs), or they can be concentrated on the same circuit board, fully balancing performance and cost. When the low beam light source 10 and the high beam light source 20 are installed on different circuit boards 30, the circuit boards 30 are connected by FPCBs, providing more flexibility in layout. Meanwhile, the low beam light-emitting element 12 and the high beam light-emitting element 22 adopt a small-angle inclined opening design. If the low beam light source 10 and the high beam light source 20 are arranged laterally on the same circuit board, the FPCB connection can be eliminated, thereby reducing manufacturing costs. In this case, the low beam light-emitting element 12 and the high beam light-emitting element 22 adopt a horizontal opening design. The flexible design of inclined and horizontal openings can adapt to the lighting needs and appearance styles of different vehicle models, achieving a high degree of unity between functionality and personalization.

[0054] Optionally, the headlight module consists of at least two high beam modules and at least one low beam module. The at least two high beam modules are arranged on opposite sides of the at least one low beam module along the lateral direction, forming a "sandwich" arrangement of "high beam module + low beam module + high beam module". This arrangement not only makes the functional distribution of the headlights compact and clear, but also achieves effective integration of the high beam and low beam functional modules, while also satisfying aesthetic appearance and overall coordination.

[0055] For example, such as Figure 5As shown, the headlight module consists of two high beam modules and one low beam module arranged symmetrically in the horizontal direction. The low beam module is located in the middle, and the high beam modules are located on both sides. The low beam module has two optical cavities. Specifically, the low beam light source 10 is located in the middle position, and the high beam light source 20 is located on both sides. Correspondingly, the two low beam reflectors 13 are also located in the middle position, while the two high beam reflectors 21 are located on both sides.

[0056] Two low-beam reflectors 13 and two high-beam reflectors 21 constitute four independent reflective cavities, each used to reflect light emitted from its corresponding light source. The shape and position of each reflective cavity should be precisely designed to maximize the light reflection efficiency and directional control. Through this partitioned design, each reflective cavity operates independently, avoiding cross-interference of light paths, thereby ensuring clear light patterns for both low and high beams and that the light paths do not interfere with each other.

[0057] The light-incident surfaces of the two low-beam reflectors 13 and the corresponding low-beam emitters 12 can be designed as a single smooth curved surface. The light-incident surfaces of the two high-beam emitters 22 are distributed on both sides, dividing the light-incident area into three light-incident areas: the middle area is used to receive the light reflected by the two low-beam reflectors 13 and the low-beam III zone forming structure 11, making the low-beam light pattern more uniform; the two side areas receive the light reflected by the corresponding high-beam reflectors 21 respectively.

[0058] Furthermore, the light-emitting surface of the low beam light-emitting element 12 and the light-emitting surfaces of the two high beam light-emitting elements 22 can be designed as a single smooth curved surface, forming a unified lighting area. This design not only improves the overall light uniformity of the headlight module but also achieves visual consistency and aesthetics.

[0059] Optionally, such as Figure 3 and Figure 4 As shown, the low beam module also includes a light shield 14. A cutoff line structure 141 is formed at the end of the light shield 14 near the low beam output element 12. The cutoff line structure 141 is used to form a main low beam pattern with a bright and dark cutoff line. It should be understood that by reasonably setting the positional relationship between the cutoff line structure 141 and the low beam source 10 or the positional relationship between the cutoff line structure 141 and the low beam reflector 13, the gradient of the bright and dark cutoff line of the formed main low beam pattern can be reduced to meet regulatory requirements, making the transition between bright and dark cutoff lines smoother, so as to provide the driver with a better driving experience. It should be noted that the surface of the light shield 14 can be set as a reflective surface, so that part of the light emitted from the low beam source 10 is directly reflected to the low beam output element 12 by the low beam reflector 13, and part of the light can be reflected to the light shield 14 by the low beam reflector 13 first, and then reflected a second time by the reflective surface of the light shield 14 to the low beam output element 12, thereby improving the utilization rate of light and the brightness value of the low beam pattern.

[0060] Optionally, such as Figure 4 As shown, a third dimming structure 142 is provided on the reflective surface of the light-shielding plate 14. The third dimming structure 142 can be a side-patterned structure. By setting precise textures or microstructures on the reflective surface, the side-patterned structure can change the reflection angle and direction of light, thereby reducing the influence of stray light, reducing bright stripe defects in road illumination, ensuring the overall uniformity of the lighting area, and providing drivers with a clearer and glare-free visual environment when driving at night. The geometry, arrangement, and distribution position of the third dimming structure 142 can be optimized according to the required optical effect.

[0061] Optionally, such as Figure 9 and Figure 10 As shown, at least one of the upper and lower sides of the light-emitting surface of the low beam light-emitting element 12 and / or at least one of the upper and lower sides of the light-emitting surface of the high beam light-emitting element 22 are also provided with a third dimming structure 142 to further reduce the influence of stray light.

[0062] Optionally, such as Figure 11 and Figure 12 As shown, a first pattern structure 131 is provided on the reflective surface of the low-beam reflective element 13. The first pattern structure 131 is one or more combinations of a rhomboid planar micro-pattern, a raindrop structure, a stripe structure, a leather texture structure, or a mesh pattern structure. These pattern structures can precisely control the scattering, refraction, or reflection characteristics of light, thereby reducing bright stripe defects in overlapping areas of corresponding light patterns from different low-beam optical cavities, making the low-beam illumination more uniform, and improving the overall luminous efficiency.

[0063] When there are multiple low beam modules, the light patterns of adjacent light modules may produce bright stripe defects in the overlapping area, that is, the brightness value of the overlapping area is too high, forming a glaring light band. By setting a first pattern structure 131 on at least one of two adjacent low beam reflectors 13, for example, a diamond-shaped planar micro-pattern can be set on one low beam reflector 13, while a raindrop structure can be set on the adjacent low beam reflectors 13. The superposition of these two different pattern structures can effectively reduce the overlapping light rays, optimize the light pattern in the overlapping area, and uniformly transition the boundary between adjacent light patterns, thereby eliminating the phenomenon of excessive brightness and unevenness in the light pattern superposition area. Similarly, when there are multiple high beam modules, the phenomenon of excessive brightness and unevenness in the light pattern superposition area can also be eliminated by setting a first pattern structure 131 on at least one of two adjacent high beam reflectors 21.

[0064] Optionally, such as Figure 11 As shown, a first pattern structure 131 is provided on the reflective surface of the reflective element 15 in the low beam III zone to further improve the uniformity of the light pattern in the low beam III zone.

[0065] Optionally, such as Figure 13and Figure 14 As shown, a second pattern structure 121 is provided on the light-emitting surface of the low beam emitting element 12 and / or the high beam emitting element 22. The second pattern structure 121 is one or more combinations of a rhomboid planar micro-pattern, a raindrop pattern, a stripe pattern, a leather texture pattern, or a mesh pattern pattern to increase the uniformity of the illumination pattern and further adjust the gradient of the near beam cutoff line to meet regulatory requirements.

[0066] Optionally, such as Figures 1 to 3 As shown, the headlight module also includes a heat sink 40, which is mainly responsible for conducting heat from the circuit board 30, preventing the circuit board 30 from overheating. In addition, the heat sink 40 also functions as a structural component, with various optical elements installed at different positions on the heat sink 40 according to optical requirements. The circuit board 30 is directly mounted on the heat sink 40, forming an efficient heat conduction path. The side of the heat sink 40 closest to the circuit board 30 is used to fix the low beam reflector 13, the low beam III zone reflector 15, and the high beam reflector 21, ensuring that these elements can complete primary light reflection in fixed positions. The light shield 14 and the low beam III zone forming structure 11 are installed in the middle of the heat sink 40. This design allows the light shield 14 to effectively block unnecessary light while also providing secondary light adjustment for some beams. The low beam emitting element 12 and the high beam emitting element 22 are installed on the front side of the heat sink 40, ensuring that the emitted light achieves high-quality illumination according to the optical design. Preferably, the light shield 14 and the low beam III zone form a structure 11 and a heat sink 40 are integrally molded, which reduces the number of parts, increases structural precision, and reduces cost and installation complexity.

[0067] Overall, the arrangement of the optical components, combined with the heat conduction capability of the heat sink 40, achieves a balance between the overall heat dissipation efficiency and optical performance of the headlight module. This also reduces the need for individual support components, thereby lowering assembly complexity and production costs. More importantly, this integrated design reduces the size of the headlight module, providing more possibilities for compact design and diverse headlight shapes.

[0068] In another aspect of this application, a vehicle lamp is provided, including any of the above-described vehicle lamp modules. Since the vehicle lamp uses the aforementioned vehicle lamp module, it also has the same beneficial effects as the vehicle lamp module, which will not be elaborated further here.

[0069] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
