Description

Technical Field

[0001] This utility model belongs to the field of automotive lighting technology, and specifically relates to a high beam lighting module, a headlight, and a vehicle. Background Technology

[0002] In recent years, with the rapid improvement of automotive industrial design and intelligence, automotive lighting systems have gradually evolved from basic functional components into key units affecting the overall aesthetics, safety performance, and energy efficiency of vehicles. Especially in the field of headlights, to align with the trend towards compact and flattened front-end designs, optical modules need to achieve efficient, uniform, and regulatory-compliant lighting effects within a limited space. Against this backdrop, flattened headlight modules have emerged, typically referring to compact optical structures with significantly reduced vertical dimensions and relatively larger horizontal dimensions. This design not only meets the demands of new energy vehicles for lightweighting and low wind resistance but also better suits the market's need for personalized appearance.

[0003] In current automotive lighting technology, flat modules generally use lenses divided into multiple independent areas. Each area generates a specific light pattern (such as a converging or diffusing spot) through optical surface design. Multiple areas are superimposed to form a complete lighting effect, achieving a multi-functional light pattern. However, this strategy of "independent design of separate areas and superposition to synthesize light patterns" has led to a series of prominent contradictions in practice:

[0004] First, the surge in the number of zones directly constrains the module's spatial efficiency and optical performance. To achieve the high center illumination and wide field-of-view coverage required for high-beam functionality, 3–4 independent converging zones are often needed for long-distance illumination, along with 2–3 diffusion zones for horizontal widening. This increase in the number of zones inevitably leads to a significant increase in the lateral dimensions (length) of the lenses or optical elements, directly conflicting with the pursuit of compact space in flat modules. Furthermore, optical interference reduces overall light efficiency, and the sophisticated multi-zone structure significantly increases the difficulty and cost of lens manufacturing and assembly.

[0005] Secondly, it is difficult to balance the optical connection and aesthetic continuity between the zones. When multiple optical zones are arranged side by side or superimposed, optical breaks or dark areas that are visible to the human eye can easily appear at the boundaries of each zone, giving a "striped" appearance that disrupts the overall integrity and aesthetics of the lens. Especially when the headlights are not illuminated, the boundaries of the zones may be clearly visible, affecting the overall quality of the headlights.

[0006] Furthermore, under stringent power consumption constraints, traditional zoning schemes struggle to balance increased illuminance with energy control. While increasing the number of zones can improve lighting performance, it leads to a linear increase in system power consumption.

[0007] Therefore, how to provide an innovative optical architecture or module design concept that can fundamentally reduce the number of optical partitions, while maintaining or even improving illumination brightness and width, effectively reducing lens length and eliminating visible partition boundaries, is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0008] The purpose of this invention is to provide a high beam lighting module, a vehicle headlight, and a vehicle that can effectively reduce the number of optical zones and, while ensuring lighting brightness and width, effectively reduce the length of the lens.

[0009] To solve the above-mentioned technical problems, this utility model provides a high beam lighting module, which includes three sections, each of which includes a light source assembly, a reflector assembly, and a module lens;

[0010] The middle section is called the middle section. In the middle section, the reflector bowl assembly includes three continuously arranged reflective surfaces. The three reflective surfaces are located near the focal point of the module lens in the middle section. Each reflective surface is correspondingly provided with a light source assembly. The reflective surface located in the middle and the corresponding light source assembly form a central converging light pattern in the module lens, while the reflective surfaces located on both sides and the corresponding light source assemblies form a diffused light spot in the module lens.

[0011] The partitions adjacent to each other on both sides of the middle partition are both end partitions. In each end partition, the reflector bowl assembly includes a reflective surface. The reflective surface is located at the focal point of the module lens of the end partition. A light source assembly is correspondingly disposed on the reflective surface. The reflective surface and the corresponding light source assembly form a converging light spot in the module lens.

[0012] The middle partition and the two end partitions are separated by partition partitions.

[0013] Optionally, in the above-mentioned high beam lighting module, the reflective surface of each of the reflector bowl components is a parabolic surface or an ellipsoid.

[0014] Optionally, in the above-mentioned high beam lighting module, the focal point of the reflective curved surface of the two end partitions is the focal point of the corresponding module lens, and the focal point of the reflective curved surface of the middle partition is the focal point of the corresponding module lens.

[0015] Optionally, in the above-mentioned high beam lighting module, the module lenses of the three partitions are integrally formed.

[0016] Optionally, in the above-mentioned high beam lighting module, the reflector bowl assembly of the middle section is a one-piece molded structure.

[0017] Optionally, in the above-mentioned high beam lighting module, the light source component is an LED lamp.

[0018] Optionally, in the above-mentioned high beam lighting module, the three light source components of the middle section are arranged at equal intervals in a straight line on a circuit board.

[0019] Optionally, in the above-mentioned high beam lighting module, the distance between the reflector bowl assembly located at the two end partitions and the module lens is greater than the distance between the reflector bowl assembly located in the middle partition and the module lens.

[0020] This utility model provides a vehicle light, including the high beam lighting module as described above.

[0021] This utility model provides a vehicle, including the headlights as described above.

[0022] This utility model provides a high beam lighting module, the advantages of which are:

[0023] The system is divided into three zones. The two end zones each have independently distributed converging zones, each equipped with an independent reflector bowl assembly and light source assembly. The reflector bowl assembly is precisely positioned near the collimation focal point of the corresponding module lens. The superposition of the light spots from the reflector bowls in the two end zones creates a strong converging spot with enhanced central illumination, thus reducing the lateral size of the module lens. The middle zone employs a three-reflective surface confocal design. The light source assembly corresponding to the central reflector bowl directly generates the central converging spot, while the reflector bowls on both sides create a diffused spot through optical path deflection. This achieves dual-beam output in a single zone, enabling the middle zone to simultaneously possess converging and diffused functions. This configuration effectively reduces the number of optical zones, ensuring illumination brightness and width while significantly reducing lens length.

[0040] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0041] The core of this utility model is to provide a high beam lighting module, a vehicle headlight and a vehicle, which can effectively reduce the number of optical zones and effectively reduce the lens length while ensuring the brightness and width of the lighting.

[0042] To enable those skilled in the art to better understand the technical solutions provided by this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] For details, please refer to Figures 1-5This utility model provides a high-beam lighting module comprising three sections arranged horizontally, from left to right: a left section, a middle section, and a right section. The left and right sections are symmetrical in structure and have the same function, and can be collectively referred to as the two end sections. The middle section and the two end sections are separated by a partition 300. By physically separating these three sections, crosstalk between different sections is effectively prevented, ensuring the purity of the light pattern.

[0044] Each section includes a light source assembly 100, a reflector bowl assembly 200, and a module lens 400. The light emitted by the light source assembly 100 is reflected by the reflector bowl assembly 200 to the module lens 400, and then reflected by the module lens 400 to the outside of the vehicle.

[0045] In the middle section, the reflector bowl assembly 200 includes three consecutively arranged reflective surfaces located near the focal point of the module lens 400 in the middle section. Each reflective surface corresponds to a light source assembly 100. The three reflective surfaces have different optical functions. The middle reflective surface and its corresponding light source assembly 100 form a centrally converging light pattern in the module lens 400, ensuring that the reflected light forms a nearly parallel beam, efficiently converging the light. The reflective surfaces on both sides and their corresponding light source assemblies 100 form diffused light spots in the module lens 400 through optical path deflection, achieving single-section dual-beam output.

[0046] The central section is the key area for realizing the core lighting function, and its width accounts for approximately one-half to two-thirds of the width of the entire module lens 400. The central section is equipped with three independent light source components 100.

[0047] In each of the two end sections, the reflector bowl assembly 200 includes an independent reflective surface. The reflective surface is located at the focal point of the module lens 400 of the two end sections. A light source assembly 100 is correspondingly provided on the reflective surface. The reflective surface and the corresponding light source assembly 100 form a converging light spot on the module lens 400.

[0048] It should be noted that the light from the LED light source corresponding to the central reflective surface of the middle section, after reflection, forms a relatively concentrated beam. After passing through the module lens 400, it can form a high-brightness centrally converged light pattern, such as... Figure 6 As shown. Light rays from the two reflective surfaces, after being reflected and diffused, form a diffused light spot with relatively uniform brightness and a wide range after passing through the module lens 400, such as... Figure 7 As shown, these two diffused light spots are positioned precisely on either side of the central converging light pattern, serving to fill and widen the overall light spot, thus enhancing the width of the overall light pattern. Figure 8 As shown.

[0049] To further enhance nighttime driving safety, this utility model provides a high-beam lighting module divided into three zones. The two end zones each have independently distributed converging zones, each equipped with an independent reflector bowl assembly 200 and a light source assembly 100. The reflector bowl assembly 200 is precisely positioned near the collimation focal point of the corresponding module lens 400. The light spots from the reflector bowls in the two end zones are superimposed (the light paths are aligned, all pointing towards the center, thus creating a converging effect), forming a strong converging light spot with enhanced central illumination, thereby reducing the lateral size of the module lens 400. The middle zone innovatively employs a three-reflective curved surface confocal design. The light source assembly 100 corresponding to the central reflector bowl directly generates the central converging light spot, while the reflector bowls on both sides form diffused light spots through light path deflection, achieving dual-beam output in a single zone. This design enables the middle zone to simultaneously possess converging and diffused functions, eliminating the additional space required by traditional diffused zones while maintaining a 10° illumination width. This optical innovation reduces the number of optical zones from more than five in traditional solutions to three, compressing the lateral size of the high beam module to 70% of that of traditional solutions, significantly optimizing space efficiency and appearance. This design effectively reduces the number of optical zones, ensuring both brightness and width while minimizing lens length, resulting in a high beam module that combines high brightness with a compact, space-optimized design.

[0050] This solution achieves a high beam center illuminance of 120 lux (test distance 25m) with low power consumption using 5 light source components (100). This design fundamentally resolves the conflict between high brightness, compact space, and aesthetics, providing key technical support for the trend towards flattened and low-power automotive lighting.

[0051] In specific embodiments, the reflective surface of each reflector bowl assembly 200 is a parabola or an ellipsoid. The reflective surface of the reflector bowl assembly 200 includes, but is not limited to, a strictly parabolic surface, but may also be an ellipsoid, a hyperboloid, or other free-form surface (i.e., a parabolic-like surface) that can guide light in the desired direction.

[0052] Specifically, the focal points of the reflective curved surfaces at both ends are the focal points of the corresponding module lens 400, and the focal point of the reflective curved surface in the middle section is also the focal point of the corresponding module lens 400. Specifically, the middle section is typically designed as a standard paraboloid or paraboloid-like surface of revolution, with the corresponding light source assembly 100 precisely positioned at the focal point of this paraboloid. The curved surface design of the two end sections may be specially optimized (e.g., using aspherical or freeform surfaces) to not only reflect light but also to diffuse it laterally to a certain extent.

[0053] The layout of the middle and end sections outputting different light patterns cleverly combines direct convergence and lateral diffusion light paths, achieving efficient utilization of light energy and optimization of light spot quality. At the same time, the structure is compact, which is in line with the development trend of flattening and miniaturizing automotive lights.

[0054] In a specific embodiment, the three-part module lens 400 is a one-piece molded structure. The module lens 400 can be a single lens or a lens group composed of multiple lenses.

[0055] The three zones utilize a single, integrally molded module lens 400. The module lens 400 can be a single plano-convex or biconvex lens covering all three zones, providing final collimation and projection of the beams from each zone. In another embodiment, the module lens 400 can also be designed as a composite lens with different optical power in each corresponding area of ​​the zone to further optimize the beam pattern. The optical systems for the middle and end zones can be independently optimized for their specific beam pattern requirements.

[0056] In a specific embodiment, the reflective bowl assembly 200 of the middle section is a one-piece molded structure. The three reflective surfaces contained in the reflective bowl assembly 200 of the middle section are physically seamlessly connected, but are optically independent.

[0057] The above configuration, in which the module lens 400 and the reflector bowl assembly 200 are both integrally molded, can reduce problems caused by gaps and connections, and improve the stability of the structure.

[0058] In a specific embodiment, the light source component 100 is an LED lamp; in other embodiments, the light source component 100 may also be a laser diode or other high-brightness point light source.

[0059] Each light source component 100 preferably uses a high-brightness LED chip and can be independently lit or dimmed to support adaptive high beam functionality. The three independent light source components 100 can be arranged in a straight line at equal intervals on a common circuit board (such as a PCB).

[0060] When high beams are needed, all or some of the light source components 100 are illuminated. A high-brightness core light spot is generated in the central area of ​​the middle section, while the reflective surfaces on either side and the end sections together create a wide and uniform illumination area. By independently controlling the five light source components 100 (three in the middle section and one in each end section), the high beam lighting module in this case can easily achieve adaptive high beam functionality. For example, when a vehicle is detected ahead, the light source components 100 in the corresponding area can be turned off or dimmed, illuminating most of the road while creating a "dark zone" at the vehicle ahead, achieving precise illumination of the road ahead, effectively avoiding glare for oncoming vehicles, and maximizing the driver's field of vision.

[0061] like Figure 2 As shown, the distance between the reflector bowl assembly 200 located at both ends of the partition and the module lens 400 is greater than the distance between the reflector bowl assembly 200 located in the middle partition and the module lens 400. This arrangement optimizes the optical path to compensate for the optical path difference caused by the difference in partition positions, thereby ensuring that the light spots generated by all partitions can be clearly and accurately superimposed on the intended light distribution screen, ultimately forming a high-beam pattern that meets regulatory requirements and has excellent lighting effects.

[0062] In summary, this case provides an innovative optical architecture or module design concept that can fundamentally reduce the number of optical zones, effectively reduce the longitudinal size of the lens, eliminate visible zone boundaries, improve luminous efficiency, and meet the requirements of low power consumption and efficient heat dissipation while maintaining or even improving illumination brightness and width, thereby promoting the development of automotive lighting technology towards a flatter, more efficient, and more aesthetically pleasing direction.

[0063] Furthermore, this utility model also provides a vehicle headlight, including the high beam lighting module in the above-described specific embodiments. This utility model also provides a vehicle, including the vehicle headlight in the above-described specific embodiments.
