Abstract
Description
Technical Field
[0001] The present application relates to the field of automotive lighting technology, and more specifically, to a vehicle lamp module and a vehicle lamp. Background Art
[0002] With the continuous advancement of industrialization, automobiles have become an indispensable means of transportation in people's daily lives. As a core component of the automotive lighting system, headlight modules play a vital role in improving vehicle performance and safety. With the continuous improvement of consumer demand, people not only place higher demands on the lighting effects of headlight modules, but also expect them to occupy less space to adapt to the compact design trend of modern vehicles while effectively controlling costs.
[0003] However, if Figure 1 As shown in the figure, most of the common high and low beam integrated headlight modules currently on the market adopt a longitudinal arrangement of "low beam on top + high beam on bottom". In this design, the light from the low beam module and the high beam module is projected through their respective primary optical elements, occupying the upper and lower halves of the lens respectively. Therefore, the upper and lower openings of the lens must be large enough to ensure that the light efficiency of the high and low beams meets the standards. This design makes the upper and lower openings of the lens of traditional high and low beam integrated headlight modules larger, which does not meet the market demand for narrow openings. In addition, due to the limitations of this longitudinal arrangement, the low beam module and the high beam module usually need to be installed separately on two circuit boards, and cannot be integrated on the same circuit board. This not only increases the overall longitudinal size of the module, but also leads to an increase in manufacturing costs, which is not conducive to optimizing the cost of the entire vehicle.

DETAILED DESCRIPTION
[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.
[0036] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application as claimed, but merely represents selected embodiments of the present application. It should be noted that, unless there is a conflict, the various features of the embodiments of the present application may be combined with each other, and the combined embodiments are still within the scope of protection of the present application.
[0037] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.
[0038] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the product of this application is typically placed when in use. These terms are intended only to facilitate the description of this application and simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0039] Furthermore, terms such as "horizontal" and "vertical" do not necessarily mean that a component must be absolutely horizontal or overhanging, but rather that it 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 rather that it can be slightly tilted.
[0040] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.
[0041] like Figure 1 As shown, most of the prior art high and low beam integrated headlight modules adopt a longitudinal arrangement of "upper low beam + lower high beam". In this design, the light emitted by the first low beam light source 1110 and the first high beam light source 1210 are respectively reflected by the low beam reflection element 1120 and the high beam reflection element 1220 to the first lens 200 and then emitted. The low beam light and the high beam light occupy the upper and lower halves of the first lens 200. Therefore, the upper and lower openings of the first lens 200 must be large enough to ensure that the light efficiency of the high and low beams meets the standards. This design makes the upper and lower openings of the first lens 200 of the traditional high and low beam integrated headlight module relatively large, which does not meet the market demand for narrow openings.
[0042] In order to solve the above problems, one aspect of the embodiments of the present application provides a vehicle lamp module, which is intended to improve the performance and space utilization efficiency of the vehicle lighting system. Figures 2 to 12As shown, the headlight module includes a low-beam module and a high-beam module arranged horizontally. The low-beam module and the high-beam module share a light-emitting element 20. The low-beam module includes a low-beam light source 111, a first low-beam reflector 112, and the light-emitting element 20, which are arranged in sequence along the light path. Light emitted by the low-beam light source 111 is reflected by the first low-beam reflector 112 to the light-emitting element 20, and then emitted and projected to form a low-beam light pattern. This layout effectively focuses and guides the light beam, forming a clear and wide illumination area, thereby improving the lighting quality of the low beam.
[0043] like Figures 2 to 5 As shown, the high-beam module includes a high-beam light source 121, and a first high-beam reflector 122, a second high-beam reflector 123, and a light-emitting element 20, arranged sequentially along the light path. Light emitted from the high-beam light source 121 is initially reflected by the first high-beam reflector 122 and then further regulated by the second high-beam reflector 123, ensuring that the light effectively reaches the light-emitting element 20 before exiting and projecting into the high-beam light pattern. The provision of the second high-beam reflector 123 fully utilizes the high-beam light and enhances the intensity of the high-beam illumination, providing the driver with a wide field of vision and ensuring driving safety during nighttime driving.
[0044] In addition, by setting the second high-beam reflection element 123, the propagation path of the high-beam light can be changed, the low-beam module and the high-beam module can be arranged horizontally, and the light of the two horizontally arranged modules can be emitted from the same light-emitting element 20, thereby realizing a compact design of the module, reducing the size of the headlight opening along the vehicle height direction, and meeting the demand of the headlight market for a narrow opening shape.
[0045] Alternatively, as Figure 5 As shown, the first high-beam reflector 122, through precise optical design, focuses light emitted by the high-beam light source 121 at its focal point after reflection, coinciding with or being within 2 mm of the focal point 20a of the light-emitting element 20. This design, in which the focal point of the first high-beam reflector 122 coincides with or nearly coincides with the focal point 20a of the light-emitting element 20, allows light to be efficiently emitted through the light-emitting element 20, reducing light dispersion and loss, thereby improving the intensity and illumination distance of the high-beam lighting.
[0046] At the same time, the reflective surface of the second high-beam reflective element 123 coincides or approximately coincides with the horizontal plane where the coincidence point is located. This design can further optimize the propagation path of the light. The main function of the second high-beam reflective element 123 is to perform secondary reflection and guidance on the light initially reflected by the first high-beam reflective element 122. By aligning or approximately aligning the reflective surface of the second high-beam reflective element 123 with the horizontal plane where the coincidence point of the focus 20a is located, the light can maintain a relatively smooth and consistent propagation path after reflection, ensuring that the high-beam light can still maintain a high light efficiency after two reflections. Such a layout allows the light to maintain the brightness and intensity of the high-beam lighting when it forms a high-beam light pattern after being emitted through the light-emitting element 20, while ensuring that the lighting area of the high-beam module is more uniform and extensive. It should be noted that approximately coinciding means that the focus 20a is located within 2 mm of the reflective surface of the second high-beam reflective element 123.
[0047] Alternatively, as Figure 3 As shown, the low beam module also includes a second low beam reflecting element 113 arranged along the light path between the first low beam reflecting element 112 and the light emitting element 20. Part of the light emitted by the low beam light source 111 is reflected by the first low beam reflecting element 112 and the second low beam reflecting element 113 in sequence to the light emitting element 20 and then emitted, so that the light emitted by the low beam light source 111 can be fully utilized, thereby improving the overall light effect of the low beam module.
[0048] Specifically, the light emitted by the low-beam light source 111 is divided into two parts. The first part of the light is reflected directly by the first low-beam reflector 112 to the light-emitting element 20, creating the basic low-beam lighting effect. The second part of the light is initially reflected by the first low-beam reflector 112, then reflected again by the second low-beam reflector 113, and finally reaches the light-emitting element 20. This design not only fully utilizes the light but also ensures effective coverage at different angles, thereby improving the low-beam lighting effect.
[0049] Furthermore, the introduction of the second low-beam reflector 113 alters the propagation path of a portion of the light emitted by the low-beam light source 111, allowing more light to be effectively utilized. By optimizing the shape and arrangement of the reflector elements, the focusing power and directionality of the light can be further enhanced, ensuring a broad and uniform light pattern. This process not only improves the quality of low-beam lighting but also reduces energy loss caused by light scattering, resulting in higher light efficiency for the low-beam module in practical applications.
[0050] Optionally, the second low-beam reflecting element 113 and the second high-beam reflecting element 123 are integrally formed, or the second low-beam reflecting element 113 and the second high-beam reflecting element 123 are independently provided.
[0051] Specifically, the one-piece design has a significant stability advantage. By integrating the second low-beam reflector element 113 and the second high-beam reflector element 123 into one whole, the complexity of the components can be reduced, the assembly process can be simplified, and assembly errors can be effectively reduced.
[0052] On the other hand, a separate design approach offers greater flexibility. Because low-beam and high-beam lighting requirements differ significantly, the independent second low-beam reflector element 113 and second high-beam reflector element 123 can be individually adjusted based on specific application scenarios. For example, in city driving, low-beam lighting requires a wider coverage area, while on highways, high-beam lighting emphasizes beam penetration and long-range illumination. With independent settings, designers can independently adjust the angle, size, and position of the second low-beam reflector element 113 and second high-beam reflector element 123 to achieve the optimal lighting effect for different driving environments.
[0053] Optionally, the second low-beam reflecting element 113 and the second high-beam reflecting element 123 are metal plates, or the second low-beam reflecting element 113 and the second high-beam reflecting element 123 are plate-shaped structures with metal films coated on their surfaces.
[0054] Specifically, highly reflective metal plates, due to their superior optical properties, effectively reflect a large portion of incident light. They are typically made of aluminum or aluminum-plated alloys, which offer excellent reflective properties and corrosion resistance. During operation, when light passes through the first reflective element and enters the second reflective element, the highly reflective metal plates minimize light loss, thereby improving the overall lighting efficiency of both the low and high beam modules. This reflective mechanism not only enhances lighting brightness but also expands lighting coverage, ensuring a good field of view for the driver in all conditions.
[0055] Furthermore, coating the substrate with a highly reflective metal film can also achieve better light reflection and scattering control. This design approach not only improves reflection efficiency but also reduces material costs to a certain extent while maintaining excellent optical performance. The application of the metal film enables the reflective element to maintain a lightweight design while providing strong reflective capabilities, thus achieving overall lightweight and high performance for the module.
[0056] Alternatively, as Figures 3 to 10As shown, the low-beam light source 111 includes multiple low-beam sub-light sources, and the first low-beam reflective element 112 has multiple low-beam reflective surfaces arranged in parallel along the horizontal direction. The low-beam sub-light sources and low-beam reflective surfaces can correspond one-to-one. This correspondence effectively improves the focusing ability of light, resulting in a wider and more uniform illumination range. After light from each low-beam sub-light source is reflected by the corresponding low-beam reflective surface, it can produce a clear and concentrated lighting effect, avoiding light scattering and loss, thereby improving lighting efficiency.
[0057] In some cases, the number of low-beam light sources may exceed the number of low-beam reflective surfaces. In this case, light from at least two low-beam light sources can be reflected by the same low-beam reflective surface to the light emitting element 20. This design enhances light source utilization efficiency, maintaining efficient lighting even with a large number of low-beam light sources. This mechanism enables the module to provide a more flexible lighting solution when dealing with complex driving environments.
[0058] In specific applications, the arrangement and combination of low-beam light sources and low-beam reflectors can be adjusted to achieve the optimal lighting effect based on different lighting requirements. For example, when higher lighting intensity is required, the number of low-beam light sources can be increased; when pursuing economy and efficiency, the number of low-beam light sources can be reduced while optimizing the configuration of low-beam reflectors. This flexible design strategy enables the lighting module to adapt to different market demands and user preferences, enhancing product competitiveness.
[0059] Alternatively, as Figures 3 to 10 As shown, the high-beam light source 121 includes a plurality of high-beam sub-light sources, and the first high-beam reflecting element 122 has a plurality of high-beam reflecting surfaces arranged in parallel along the horizontal direction. The correspondence between the high-beam sub-light sources and the high-beam reflecting surfaces can be achieved in two ways. The first way is that each high-beam reflecting surface corresponds one-to-one with one high-beam sub-light source. Under this configuration, the light emitted by each high-beam sub-light source is reflected by the corresponding high-beam reflecting surface, and then reflected to the light-emitting element 20 through the second high-beam reflecting element 123. This one-to-one correspondence design ensures maximum utilization of light, allowing each high-beam sub-light source to independently exert its lighting capability, thereby forming a strong and concentrated high-beam lighting effect, greatly improving the safety of night driving.
[0060] The second correspondence allows for a greater number of high-beam sub-light sources than high-beam reflective surfaces. In this case, light from at least two high-beam sub-light sources can be reflected by the same high-beam reflective surface, then reflected by the second high-beam reflective element 123 to the light-emitting element 20. This design not only improves light source utilization efficiency but also provides greater design flexibility. By properly balancing the number of high-beam sub-light sources with the number of high-beam reflective surfaces, the number of components can be reduced, lowering production costs while maintaining the desired lighting intensity.
[0061] In practical applications, the combination of high-beam light sources and high-beam reflectors can be flexibly adjusted based on lighting needs. For example, in environments requiring stronger lighting, the number of high-beam light sources can be increased, while for cost-effectiveness, fewer high-beam light sources and high-beam reflectors can be used. This flexibility not only meets diverse market needs but also provides users with a superior lighting experience.
[0062] Alternatively, as Figure 11 and Figure 12 As shown, the light emitting element 20 has a light entrance surface 21 and a light exit surface 22 to efficiently direct light to the external environment. The light entrance surface 21 includes at least one low-beam light entrance surface 211 and at least one high-beam light entrance surface 212 arranged in a transverse direction. The low-beam light entrance surface 211 is arranged corresponding to the low-beam reflective surface, and the high-beam light entrance surface 212 is arranged corresponding to the high-beam reflective surface, thereby forming a precise lighting pattern.
[0063] Specifically, light emitted by the low-beam light source 111 first strikes these low-beam reflective surfaces. These surfaces are optimized to effectively reflect light toward the corresponding low-beam light-entering surfaces 211. After being reflected by the multiple low-beam reflective surfaces, the light enters the low-beam light-entering surfaces 211 and ultimately exits through the light-emitting surface 22, forming the desired low-beam light pattern. This process ensures uniformity and intensity of low-beam illumination, providing the driver with a good field of vision and enhancing driving safety during nighttime driving.
[0064] Similar to the design of low beam, the light emitted by the high beam light source 121 will also be reflected by multiple high beam reflection surfaces, and finally enter the high beam light incident surface 212, and be emitted through the light emitting surface 22 to form a high beam light pattern, so as to maximize the utilization efficiency of light and ensure the brightness and range of high beam lighting.
[0065] Alternatively, as Figures 9 to 12 As shown, the lighting module includes multiple low-beam modules and high-beam modules arranged in parallel along the horizontal direction. Correspondingly, the light-entering surface 21 of the light-emitting element 20 also includes multiple low-beam light-entering surfaces 211 and high-beam light-entering surfaces 212 arranged in parallel along the horizontal direction to accurately receive and guide light.
[0066] Specifically, light from each low-beam light source 111 ultimately strikes its corresponding low-beam light entrance surface 211 and exits through the light exit surface 22, forming a low-beam sub-beam pattern. The superposition of multiple low-beam sub-beam patterns ultimately forms the overall low-beam pattern. This superposition effect not only enhances lighting intensity but also ensures wide coverage of low-beam illumination, greatly enhancing driving safety.
[0067] Light from each high-beam light source 121 ultimately strikes its corresponding high-beam incident surface 212 and exits through the light-emitting surface 22, forming a high-beam sub-pattern. By superimposing multiple high-beam sub-patterns, an overall high-beam pattern is formed, achieving a powerful and focused high-beam illumination effect. This design ensures a clear field of view for drivers when long-range illumination is required, enhancing safety during high-speed driving.
[0068] Optionally, the light-emitting element 20 is a lens, which can be made of transparent plastic, commonly PMMA or PC, and is relatively thin overall; the light incident surface 21 of the lens is a convex surface, the light emitting surface 22 is a plane, and the multiple low-beam light incident surfaces 211 and the multiple high-beam light incident surfaces 212 of the lens should be an integrated structure, the light incident side of this integrated structure includes multiple convex surfaces arranged in parallel, and the light emitting side includes a plane.
[0069] Optionally, the lens is set in the lens holder 30, thereby providing certain support and protection for the lens, and realizing the combined installation of the lens and the lens holder 30 with the other components, thereby improving the connection stability of the headlight module, and also making the installation process simpler and improving the installation efficiency.
[0070] Optionally, a first pattern structure is provided on the light incident surface 21 , and / or a second pattern structure is provided on the light exit surface 22 .
[0071] Specifically, if Figure 11 and Figure 12 As shown, the light incident surface 21 of the lens can be provided with a first pattern structure, or it can remain smooth. The first pattern structure can be a grid pattern, and the size and height of the grid pattern can be flexibly adjusted according to needs. Providing the first pattern structure on the low beam light incident surface 211 can reduce the gradient of the low beam cutoff line. This design can reduce the visual sharpness of the low beam cutoff line by changing the light distribution pattern, thereby enhancing the driver's comfort. At the same time, the soft transition of light makes the low beam lighting more natural, avoiding glare on other drivers, thereby improving overall road safety.
[0072] The first patterned structure on the high-beam incident surface 212 evens out and diffuses the light. This design, by forming a microstructure on the high-beam incident surface 212, effectively expands the light coverage, making the high-beam pattern wider and more uniform. This light distribution ensures a wider field of view for drivers when long-range illumination is required, enhancing safety at high speeds and in adverse weather conditions. Furthermore, the diffuse nature of the light helps reduce glare from the high-beam illumination on other road users, maintaining a favorable driving environment.
[0073] Furthermore, a second pattern structure can be provided on the light-exiting surface 22 of the lens, or the surface can remain smooth. The second pattern structure can be transverse stripes, and the spacing and height of the transverse stripes can be flexibly adjusted based on the specific vehicle model and market demand. Providing a second pattern structure on the light-exiting surface 22 can ensure a smoother and more uniform transition between multiple sub-light patterns when superimposed.
[0074] Alternatively, as Figure 9 and Figure 10 As shown, the first low-beam reflector element 112 and the first high-beam reflector element 122 form an integrated structure. Since the low-beam reflective surface and the high-beam reflective surface are clean surfaces, a pick-up structure 40 is provided on this integrated structure to prevent contamination of the low-beam reflective surface and the high-beam reflective surface when removing or installing the first low-beam reflector element 112 and the first high-beam reflector element 122. The pick-up structure 40 is located between the first low-beam reflector element 112 and the first high-beam reflector element 122, making it easy to remove without affecting the function of the low-beam reflective surface and the high-beam reflective surface. The pick-up structure 40 has a length range of 10-30 mm and a width range of 5-10 mm, and its shape includes but is not limited to a rectangle and a triangle.
[0075] Alternatively, as Figure 6 As shown, the headlight module also includes a circuit board 50 and a heat sink 60. The low-beam light source 111 and the high-beam light source 121 are mounted on the same circuit board 50, which not only enables the low-beam light source 111 and the high-beam light source 121 to emit light, but also saves costs. The heat sink 60 is used to achieve the heat dissipation function of the headlight module. By fixing the circuit board 50 to the heat sink 60, the light source of the lighting module is fixed to the heat sink 60. Then, the multiple first low-beam reflective elements 112 and the first high-beam reflective elements 122 in an integrated structure are fixed to the heat sink 60. By connecting the lens bracket 30 to the heat sink 60, the lens is also connected to the heat sink 60. This improves the connection stability of the headlight module. The structure is simple, the installation process is simple, and the installation efficiency can be improved, reducing structural and installation costs.
