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.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] The following is for reference. Figures 1-6 The optical structure 100 according to an embodiment of the present invention is described.

[0032] like Figures 1-6 As shown, the optical structure 100 according to an embodiment of the present invention includes a first light guide 1 and a second light guide 2 connected together. The second light guide 2 is located on the light-emitting side of the first light guide 1. The first light guide 1 has a first light-incident surface 11 and a first light-emitting surface 12. The second light guide 2 has a second light-incident surface 211 and a second light-emitting surface 212. The second light-incident surface 211 is located on the light-emitting side of the first light-emitting surface 12 and is spaced apart from the first light-emitting surface 12. The first light-emitting surface 12, the second light-incident surface 211 and the second light-emitting surface 212 are all provided with diffusion patterns to diffuse light in multiple directions.

[0033] In other words, when the light-emitting element emits light, the light enters the first light guide 1 from the first light-incident surface 11. If the first light-emitting surface 12 has a diffusion pattern, the light will undergo diffuse reflection and refraction due to the uneven surface structure when it is emitted, and the originally concentrated beam of light will be decomposed into multi-directional scattered light. Subsequently, these scattered lights will further diverge in the interval area between the first light guide 1 and the second light guide, and cross and overlap to form a complex light field. After entering the second light guide 2, if the second light-incident surface 211 and the second light-emitting surface 212 are patterned, the light will undergo secondary and tertiary scattering, and finally be emitted at multiple angles. When viewed from different perspectives, it presents a dazzling effect of alternating brightness and darkness. When the light-emitting element is not working, ambient light can also enable the optical structure 100 to achieve a dazzling effect. Specifically, when ambient light shines on the surface with a diffusion pattern, the uneven structure of the pattern reflects the light in multiple directions, forming a visual effect similar to frosted reflection. Meanwhile, the space between the first light guide 1 and the second light guide 2 causes light to interfere, producing alternating bright and dark interference fringes, further enhancing the visual flickering effect. Thus, even without an internal light source, the optical structure 100 can still exhibit a static and dazzling beauty by reflecting, scattering, and interfering with ambient light.

[0034] Therefore, the optical structure 100 according to the present invention is separated by a first light-emitting surface 12 and a second light-incident surface 211, and both the first light-emitting surface 12, the second light-incident surface 211 and the second light-emitting surface 212 are provided with diffusion patterns, so that the light emitted by the light-emitting element undergoes three scatterings, thereby enabling the optical structure 100 to have a brilliant aesthetic when the light-emitting element is emitting light or not.

[0035] In some embodiments of this utility model, such as Figures 1-6 As shown, the first light-incident surface 11 includes a central region and an outer ring region surrounding the outer periphery of the central region. At least a portion of the outer ring region extends curved toward the first light-emitting surface 12 along the direction from the central region to the outer ring region. At least a portion of the outer ring region is configured as a total reflection surface 112. At least a portion of the central region has a groove 111 recessed toward the first light-emitting surface 12. The bottom wall and peripheral wall of the groove 111 are respectively configured as a first optical surface 1111 and a second optical surface 1112. Both the first optical surface 1111 and the second optical surface 1112 are used to receive light emitted by the light-emitting element. The first optical surface 1111 is an arc surface recessed toward the direction away from the first light-emitting surface 12.

[0036] In other words, the first light-incident surface 11 of the optical structure 100, through the differentiated design of the central region and the outer ring region, combined with the construction of the first optical surface 1111 and the second optical surface 1112 and the total internal reflection principle of the total internal reflection surface 112, can achieve relatively efficient light focusing. Specifically, the first light-incident surface 11 is divided into a central region and an outer ring region. The outer ring region at least partially bends and extends towards the first light-emitting surface 12 to form the total internal reflection surface 112. The central region is provided with a groove 111 recessed towards the first light-emitting surface 12. The bottom wall and the peripheral wall of the groove 111 respectively serve as the first optical surface 11. The first optical surface 11 and the second optical surface 1112 receive light. When the light-emitting element emits light, the light projected toward the first optical surface 1111 (bottom wall) can directly enter the first light guide 1. The arc design of the first optical surface 1111 is conducive to the convergence of light. The second optical surface 1112 (peripheral wall) uses an inclined angle design to project light toward the total reflection surface 112. The curved and extended structure of the total reflection surface is like a "reflector bowl", which can reflect light toward the first light-emitting surface 12, so that the light emitted by the light-emitting element can be better focused toward the first light-emitting surface 12.

[0037] For example, when light is projected toward the total reflection surface 112, it can effectively force the light that might otherwise diverge back to the central region. For instance, oblique light from the edge of the light-emitting element, after being reflected by the total reflection surface 112, can be guided to the vicinity of the central optical axis and superimposed with the light from the central region. Thus, the central region and the outer ring region work together to guide the light axially within the first light guide 1, forming a concentrated beam with a small divergence angle when emitted from the first light-emitting surface 12, achieving a focusing effect.

[0038] In some embodiments of the present invention, at least a portion of the first optical surface 1111 and / or the total reflection surface 112 is provided with a diffusion pattern.

[0039] In other words, the first optical surface 1111 can have a diffusion pattern on a portion or all of it, and the total reflection surface 112 can have a diffusion pattern on a portion or all of it.

[0040] For example, if a portion of the first optical surface 1111 is provided with a diffusion pattern, it can reduce light intensity unevenness by scattering edge light through the diffusion pattern area while retaining the light-gathering ability of the central area; if the entire first optical surface 1111 is provided with a diffusion pattern, the light beam can be evenly dispersed, avoiding glare. When a portion of the total reflection surface 112 is provided with a diffusion pattern, the absence of a diffusion pattern area maintains the light-gathering effect, while the diffusion pattern area scatters the reflected light from multiple angles, enhancing the sense of layering in the light field; if the entire total reflection surface 112 is provided with a diffusion pattern, the reflected light can form soft diffused light. In addition, the diffuse reflection of ambient light by the diffusion pattern can improve the static aesthetics of the structural component, allowing the optical structural component 100 to achieve dynamic adjustment and balance in terms of light-gathering efficiency, light emission uniformity, and visual effect.

[0041] In some embodiments of this utility model, such as Figures 1-6 As shown, the diffusion pattern provided on the first optical surface 1111 is a corn kernel pattern that is recessed toward the inside of the first light guide 1, and / or, the diffusion pattern provided on the total reflection surface 112 is a corn kernel pattern that is recessed toward the inside of the first light guide 1.

[0042] In other words, the special raised structure of the corn kernel pattern resembles a corn kernel, and its surface curvature and arrangement can precisely control the light. On the first optical surface 1111, this diffused pattern can disperse the concentrated incident light into multiple angles, avoiding the problem of localized high brightness or glare caused by excessive light focusing, making the emitted light more uniform and softer; at the same time, its irregular raised distribution can disrupt the light propagation path, increase the interference and superposition between light rays, and make the optical effect more layered and dynamic.

[0043] The total reflection surface 112 features a corn kernel pattern. When light is reflected, the uneven surface of the pattern causes multiple reflections and refractions, breaking down the originally unidirectional reflected light into multiple beams, further enhancing the light diffusion effect after focusing. Furthermore, in the absence of a light source, the diffuse reflection of ambient light by the corn kernel pattern allows the surface of the optical component 100 to exhibit dynamic light and shadow changes, combining practicality and aesthetics. This significantly improves the overall quality of the optical component 100 in terms of both optical performance and visual appeal.

[0044] For example, the height of the raised pattern on each corn kernel is approximately 0.1 mm, or for example, it can be between 0.09 mm and 1.2 mm, and this application does not impose any limitation.

[0045] In some embodiments of this utility model, the distance H between the first light-emitting surface 12 and the second light-incident surface 211 satisfies: 0.5mm≤H≤2mm.

[0046] For example, when H is 0.5 mm, the propagation path of light between the first light guide 1 and the second light guide 2 is short, resulting in low light energy loss and ensuring high light transmission efficiency. The compact structure also facilitates the miniaturization and integration of the optical component 100. As H increases to 1 mm, the light has more space to diverge and interfere, and light rays from different angles superimpose, making the light distribution received by the second light guide 2 more uniform and reducing local brightness differences. When H approaches 2 mm, the spacing promotes complex diffuse reflection and refraction effects, significantly enhancing the brilliance and layering of the optical component 100. Especially when the light-emitting element is working, multi-angle scattered light creates a dazzling dynamic visual effect. Furthermore, this distance range effectively avoids problems such as poor light transmission due to excessively small spacing, or light energy loss and structural looseness due to excessively large spacing, achieving the optimal balance between optical performance and physical structure.

[0047] For example, H can also be 0.7mm, 0.9mm, 1.1mm, 1.3mm, 1.5mm, 1.7mm, or 1.9mm.

[0048] In some embodiments of this utility model, such as Figures 1-6 As shown, the diffusion pattern on the first light-emitting surface 12 is a corn kernel pattern, and it is arranged in multiple rows and columns on the first light-emitting surface 12. The corn kernel pattern between two adjacent rows is arranged in a stepped manner, and / or the corn kernel pattern between two adjacent columns is arranged in a stepped manner.

[0049] In other words, the stepped corn kernel pattern allows light to undergo multiple reflections and refractions at different heights within the pattern. Compared to a conventional flat arrangement, this results in a wider range of light scattering angles, preventing light from concentrating in a single direction and effectively eliminating bright spots and dark areas, leading to a more uniform light distribution. Simultaneously, this staggered structure disrupts the light propagation path, increasing interference between light rays and enhancing the sense of depth and three-dimensionality of the light field. Visually, when the light-emitting component is working, the stepped corn kernel pattern allows light to be emitted from multiple angles, creating a dynamic, shimmering effect that enhances its visual appeal. In its non-emitting state, its three-dimensional structure reflects ambient light, presenting a dynamic interplay of light and shadow textures, effectively improving the visual effect of the optical structure 100.

[0050] In some embodiments of this application, such as Figures 1-6 As shown, the second light-incident surface 211 and / or the second light-exit surface 212 are provided with irregular polyhedral patterns.

[0051] In other words, each facet of the irregular polyhedral pattern can act as an independent microprism. When light is incident, it is reflected and refracted on these surfaces of varying shapes and angles. When light enters from the second light-incident surface 211, the polyhedral pattern can disperse the light to different areas of the second light guide 2, avoiding localized over-brightness or darkness caused by concentrated light, thus achieving a more uniform light distribution. If the second light-emitting surface 212 is provided, the emitted light will be further dispersed, forming multi-angle scattered light, significantly enhancing the diffusion effect of the optical structure 100 and reducing glare. When the light-emitting element emits light, the light passing through the polyhedral pattern can present a dazzling and ever-changing light and shadow like a diamond. Observed from different angles, one can see light spots that are interlaced with light and dark, shimmering and flowing, with a good visual impact. When the light-emitting element does not emit light, ambient light shines on the surface of the polyhedral pattern, presenting a dazzling and ever-changing light and shadow like a diamond through diffuse reflection. Observed from different angles, one can see light spots that are interlaced with light and dark, shimmering and flowing, with a good visual impact.

[0052] Regarding the polyhedral and corn kernel patterns in this application, it should be noted that both are special designs used in the optical structural component 100 for modulating light. The polyhedral pattern simulates irregular polyhedral shapes, such as triangular pyramids and frustums, with irregular angles and side lengths on each face. The surface can be flat or slightly curved, and its distribution is random and dense, resembling a disordered combination of crushed diamonds. Each face of the polyhedral pattern acts like a miniature prism, refracting and reflecting light in multiple directions. It uniformly guides light onto the incident surface and enhances diffusion and reduces glare on the exiting surface, presenting a strong, dazzling sparkle like a diamond. The polyhedral and corn kernel patterns can achieve efficient control and visual optimization of light through their unique shapes and arrangements. The corn kernel pattern takes the shape of a corn kernel, with each pattern approximating an elliptical cylinder or frustum of a cone, rounded at the top and slightly wider at the bottom, with fine textures on the surface. They are arranged in multiple rows and columns on the optical surface, with adjacent rows and columns staggered in a stepped manner, similar to the arrangement of a corn cob. This design allows light to be reflected and refracted multiple times, increasing the scattering angle and improving the uniformity of light output.

[0053] In some embodiments of this application, such as Figures 1-6 As shown, the second light guide 2 is an integrally formed part. The second light guide 2 includes a body part 21 and a connecting part 22. The second light-incident surface 211 and the second light-outceasing surface 212 are both located on the body part 21. One end of the connecting part 22 is connected to one side of the body part 21, and the other end extends toward the first light guide 1 to connect with the first light guide 1.

[0054] In other words, the one-piece molding process can avoid light leakage and loss caused by splicing gaps, and improve the efficiency and stability of light transmission within the second light guide 2. At the same time, the one-piece molding process can reduce assembly steps, reduce production complexity and cost, and improve yield. One end of the connecting part 22 is connected to the main body 21, and the other end extends to connect with the first light guide 1. This not only enhances the mechanical connection strength between the first light guide 1 and the second light guide 2, preventing structural misalignment caused by external forces from affecting optical performance, but also allows for flexible adjustment of the distance between the two light guides, optimizing the propagation and interference effect of light in the interval area, and further improving the overall performance and reliability of the optical structure 100.

[0055] For example, the first light guide portion 1 and the connecting portion 22 can be connected by adhesive.

[0056] In some embodiments of this application, such as Figures 1-6 As shown, the first light guide part 1 is provided with a first positioning member 13, which is used to limit the relative position of the first light guide part 1 and the connecting part 22 in the first direction X, and / or the connecting part 22 is provided with a second positioning member 221, which is used to limit the relative position of the first light guide part 1 and the connecting part 22 in the second direction Y, wherein the first direction X and the second direction Y are perpendicular to each other.

[0057] In other words, the first light guide 1 and the connecting part 22 are positioned and restricted in mutually perpendicular directions by the first positioning member 13 and the second positioning member 221, which can effectively improve the assembly accuracy and performance stability of the optical structure 100. Specifically, the first positioning member 13 is disposed on the first light guide 1, which can better constrain the displacement of the connecting part 22 in the first direction X, ensuring that the second light-incident surface 211 and the first light-outceasing surface 12 maintain the designed distance, avoiding the decrease in light transmission efficiency or uneven light field distribution caused by misalignment; while the second positioning member 221 of the connecting part 22 further fixes the positions of the two parts in the perpendicular second direction Y, preventing lateral displacement from interfering with optical performance. The first positioning member 13 and the second positioning member 221 work together to construct a stable positioning system in two-dimensional space, reducing the risk of structural loosening caused by external force vibration, temperature changes and other factors. In addition, this positioning design can reduce assembly difficulty, help improve production efficiency and product yield, and at the same time ensure that the optical structure 100 maintains stable optical performance during long-term use.

[0058] For example, the first positioning member 13 may abut against one side of the connecting part 22 in the first direction X, and the second positioning member 221 may abut against one side of the first light guide part 1 in the second direction Y.

[0059] For example, the first positioning member 13 is a positioning rib, and the second positioning member 221 is a positioning rib. It is understood that the first positioning member 13 and the second positioning member 221 may also be other shapes, and this application does not limit them.

[0060] This utility model also proposes a vehicle having the optical structure 100 described in the above embodiments.

[0061] According to an embodiment of the present invention, the vehicle includes a headlight, which includes a light-emitting element and an optical structure 100 as described above. The optical structure 100 is located on the light-emitting side of the light-emitting element.

[0062] In other words, applying the aforementioned optical structural component 100 to vehicle headlights can significantly improve the headlights' lighting performance, safety, and aesthetics. Regarding lighting performance, the focusing and diffusion design of the optical structural component 100 allows for precise projection of light emitted from the light-emitting element, effectively improving the lighting range and brightness uniformity. Special structures such as polyhedral patterns and corn kernel patterns further enhance light scattering, reducing glare and providing the driver with a clear and comfortable field of vision, thus reducing nighttime driving fatigue.

[0063] Furthermore, the first positioning component 13, the second positioning component 221, and the integrally formed second light guide 2 ensure structural reliability. Even with vehicle vibrations and bumps, the optical structural component 100 maintains a precise light pattern, preventing lighting failure due to component displacement. Simultaneously, the dazzling optical effect creates dynamic light and shadow when the vehicle is moving or starting / stopping, enhancing not only the headlight's visibility but also improving driving safety through visual warnings. Moreover, its unique aesthetic design gives the headlight both a technological and decorative feel, making it beautiful both when illuminated and when not illuminated.

[0064] For example, the first light guide part 1 includes a plurality of light guide units 10, each of the light guide units 10 having a first light incident surface 11 and a first light emitting surface 12, and the plurality of light guide units 10 are arranged sequentially along a straight line.

[0065] According to the vehicle of the present utility model embodiment, by providing the optical structure 100 of the above embodiment, the vehicle headlights can have a better lighting effect, and the vehicle headlights have a dazzling aesthetic when they are emitting light or not, which can improve the user experience.

[0066] For example, the optical structure 100 of this application can also be applied to other fields, not limited to vehicles, which will not be elaborated upon in this application.
