Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and more particularly to optical devices. Background Technology

[0002] In the existing field of optical lighting, common optical devices mainly consist of a light source, a reflector, and a lens. The light source emits light, which is reflected by the reflector and then shines into the lens, and finally shines out through the lens to achieve the lighting function.

[0003] Currently, while reflectors can enhance the directionality of light, their excessive control over the direction of light means that the light reflected from the reflector cannot evenly cover the entire lens surface. When people look directly at the lens surface, they will clearly notice uneven brightness. Furthermore, since each reflector is independent, when illuminating an object, it's like multiple lights shining on the same object from different positions; the resulting shadows cannot overlap, causing ghosting. Simultaneously, there are areas between adjacent reflectors that are not illuminated, leading to dark areas and gaps on the lens surface, while some areas are excessively bright, easily causing glare and severely impacting lighting performance and user experience.

[0004] Therefore, optical devices are urgently needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an optical device that can optimize light distribution, effectively eliminate dark area breaks between adjacent reflectors, make the light distribution on the lens surface more uniform, avoid the glare caused by concentrated light leading to localized overbrightness, and prevent the illuminated object from having a ghosting problem.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] Optical device, including:

[0008] A light source assembly includes a mounting member and a plurality of light source elements, wherein the plurality of light source elements are spaced apart on the mounting member along the length direction and / or width direction of the mounting member;

[0009] A reflective assembly includes a fixing member and a plurality of reflective cups disposed on the fixing member, each of the reflective cups correspondingly covering at least one light source element and configured to collect light from the corresponding light source element;

[0010] A lens is located on the side of the reflector away from the light source assembly, and a V-shaped groove is provided on the side of the lens facing the reflector at the interval between two adjacent reflectors, so that the light irradiated into the V-shaped groove can undergo total internal reflection under the action of the groove wall.

[0011] As an alternative solution for an optical device, the lens includes a lens body and multiple lens inner cells. The multiple lens inner cells are all disposed on the side of the lens body facing the reflector and are disposed one-to-one with the reflector. The circumferential side surface of each lens inner cell forms a first reflecting surface. The first reflecting surface gradually tilts towards the center of the lens inner cell in a direction away from the lens body, so that the two first reflecting surfaces of two adjacent lens inner cells sandwich the V-shaped groove.

[0012] As an alternative to the optical device, the outer contour of the inner frame of the lens completely covers the light outlet of the corresponding reflector on the side opposite to the lens body.

[0013] As an alternative to the optical device, the first reflective surface is provided with a plurality of first microstructures, and the plurality of first microstructures are arranged at intervals along a first preset direction on the first reflective surface; or, the first reflective surface is provided with an electroplated layer.

[0014] As an alternative solution for an optical device, a plurality of second microstructures are provided on the side of the lens grid opposite to the lens body, and the plurality of second microstructures are arranged at intervals along a second preset direction on the lens grid.

[0015] As an alternative solution for an optical device, the inner surface of the reflector cup is a second reflective surface, and a plurality of third microstructures are provided on the second reflective surface, with the plurality of third microstructures arranged at intervals along a third preset direction on the second reflective surface.

[0016] As an alternative optical device, the side of the lens facing away from the reflector is a smooth plane.

[0017] As an alternative to the optical device, the optical device also includes an anti-glare shield connected to the end of the lens away from the reflective assembly, the anti-glare shield being configured to increase the anti-glare angle of the light.

[0018] As an alternative to the optical device, the anti-glare shield has a fourth microstructure on its inner surface.

[0019] As an alternative optical device, the lens and the anti-glare shield are integrated into one unit.

[0020] Beneficial effects:

[0021] The optical device provided by this invention emits light from multiple light sources spaced apart on the mounting components of the light source assembly during actual operation. The light is collected by the reflectors of the reflector assembly and then reflected before being directed towards the lens. Because the lens has V-shaped grooves at intervals between adjacent reflectors on the side facing the reflector, the light entering the V-shaped grooves undergoes total internal reflection under the action of the groove walls. This optical device optimizes light distribution, effectively eliminates dark area breaks between adjacent reflectors, makes the light distribution on the lens surface more uniform, avoids glare caused by concentrated light leading to localized overbrightness, and prevents ghosting of the illuminated object.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, 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.

[0035] This embodiment provides an optical device, such as Figures 1-5As shown, the optical device includes a light source assembly 2, a reflector assembly 3, and a lens 4. The light source assembly 2 includes a mounting member 21 and multiple light sources 22. The multiple light sources 22 are spaced apart on the mounting member 21 along its length and / or width. The reflector assembly 3 includes a fixing member 31 and multiple reflector cups 32 disposed on the fixing member 31. Each reflector cup 32 is correspondingly covered with at least one light source 22 and is used to collect light from the corresponding light source 22. The lens 4 is located on the side of the reflector cup 32 away from the light source assembly 2, and a V-shaped groove 43 is provided on the side of the lens 4 facing the reflector cup 32 at the interval between two adjacent reflector cups 32, so that the light irradiated into the V-shaped groove 43 can undergo total internal reflection under the action of the groove wall of the V-shaped groove 43.

[0036] In actual operation, the optical device emits light from multiple light sources 22 spaced apart on the mounting component 21 of the light source assembly 2. The light is collected by the reflector cup 32 of the reflector assembly 3 and reflected before being directed towards the lens 4. Since the lens 4 has a V-shaped groove 43 at the interval between adjacent reflector cups 32 on the side facing the reflector cup 32, the light illuminating the V-shaped groove 43 undergoes total internal reflection under the action of the groove wall. This optical device can optimize the light distribution, effectively eliminate the dark area discontinuity between adjacent reflector cups 32, make the light distribution on the surface of the lens 4 more uniform, avoid the glare caused by concentrated light leading to localized overbrightness, and prevent the illuminated object from showing ghosting.

[0037] like Figures 1-4 As shown, the optical device also includes a housing 1, a mounting component 21 disposed within the housing 1, a fixing component 31 fixed within the housing 1, and multiple reflectors 32 whose first ends are connected to the fixing component 31. Each reflector 32 has at least one corresponding light source component 22 covering its second end. The housing 1 provides stable support and protection for the light source assembly 2 and the reflector assembly 3. The mounting component 21 and the fixing component 31 are rationally arranged within the housing 1, enabling the multiple reflectors 32 to accurately collect light from their corresponding light sources 22. This ensures a compact and orderly internal structure of the optical device, improves overall stability and reliability, effectively avoids interference from external factors on optical performance, guarantees light transmission and reflection effects, and optimizes lighting quality.

[0038] like Figures 2-3As shown, in this embodiment, multiple light sources 22 are spaced apart on the mounting member 21 along its length. The multiple light sources 22 are arranged in a single row on the mounting member 21, which makes the optical device structure more compact and simple. This is suitable for scenarios with high space requirements or those requiring linear illumination, effectively saving internal space in the housing 1 and meeting the design requirements of miniaturized and lightweight optical devices. Furthermore, the single-row layout of the multiple light sources 22 allows for precise control of the linear propagation direction of light, reducing interference between light rays. Through the rational design of the reflector cup 32 and the lens 4, the directional convergence and projection of light can be better achieved, forming a uniform and continuous strip lighting effect.

[0039] In other embodiments, multiple light sources 22 are spaced apart on the mounting member 21 along its length and width. That is, the light sources 22 are arranged in multiple rows and columns on the mounting member 21, such as two rows and two columns, two rows and three columns, or three rows and three columns. This design can significantly improve the light flux and illumination uniformity of the optical device. By adjusting the number and spacing of each row and column of light sources 22 and rationally designing the reflector cup 32 and lens 4, the light distribution can be precisely controlled, effectively eliminating dark areas and shadows. Furthermore, in practical applications, when a row of light sources 22 fails, the remaining rows of light sources 22 can still maintain basic illumination functions, ensuring the stable operation of the lighting system.

[0040] like Figure 2 As shown, in this embodiment, multiple light sources 22 are arranged continuously and at equal intervals on the mounting member 21. This continuous, equally spaced arrangement of light sources 22 achieves a uniform lighting effect, suitable for scenarios requiring high light uniformity. In this embodiment, the spacing between two adjacent light sources 22 is not limited; designers can adaptively adjust the spacing between adjacent light sources 22 according to actual lighting needs. In other embodiments, multiple light sources 22 are arranged continuously but at non-equal intervals on the mounting member 21, which can be flexibly adjusted according to actual needs and is not specifically limited here.

[0041] like Figure 3 As shown, in this embodiment, each reflector 32 is covered with a light source 22 corresponding to its position. In other embodiments, a reflector 32 can cover two, three, four, five, or other light sources 22. The light emitted from multiple light sources 22 undergoes a first mixing after passing through the same reflector 32, and then a second mixing occurs when passing through the lens 4. After the light is evenly mixed, it is emitted from the outer surface of the lens 4 with a high degree of uniformity. The number of light sources 22 covered by the reflector 32 is not specifically limited here.

[0042] like Figures 3-6As shown, lens 4 includes a lens body 41 and multiple lens inner cells 42. Each lens inner cell 42 is located on the side of the lens body 41 facing the reflector 32 and corresponds one-to-one with the reflector 32. A first reflecting surface 421 is formed on the circumferential side of each lens inner cell 42. The first reflecting surface 421 gradually tilts towards the center of its own lens inner cell 42 along a direction away from the lens body 41, so that the two first reflecting surfaces 421 of two adjacent lens inner cells 42 form a V-shaped groove 43. The V-shaped groove 43 guides light to undergo total internal reflection, reducing light loss, filling the light gaps between adjacent reflectors 32, effectively eliminating dark area breaks, making the light distribution on the surface of lens 4 more uniform, and improving the lighting effect and visual comfort.

[0043] For ease of description, one side surface of the lens body 41 with multiple lens inner cells 42 is the inner surface of the lens body 41, and the side surface away from the multiple lens inner cells 42 is the outer surface of the lens body 41. The light emitted from the light source 22 can be transmitted from the inner surface of the lens body 41 to the outer surface of the lens body 41.

[0044] It is worth noting that when the inner lens 42 is fastened to the corresponding reflector 32, the lens body 41 is tightly attached to the fixing member 31. The lens body 41, the fixing member 31, the reflector 32, and the mounting member 21 together form a sealed space, which isolates dust and powder from the outside, effectively preventing dust and powder from entering the reflector 32, providing comprehensive protection for the light source assembly 2, and ensuring the stable operation of the optical device.

[0045] In this embodiment, the first reflective surface 421 gradually tilts towards the center of the inner lens grid 42 along the direction away from the lens body 41. The tilt angle ranges from 45 degrees to 60 degrees. Within this angle range, light illuminating the V-shaped groove 43 formed by the two adjacent first reflective surfaces 421 can undergo efficient total internal reflection under the action of the groove wall, effectively improving the light distribution, filling the light gap between adjacent reflectors 32, making the light distribution on the lens 4 surface more uniform, and optimizing the overall illumination effect. This tilt angle can be 45 degrees, 47 degrees, 49 degrees, 51 degrees, 53 degrees, etc. In practical applications, this angle will also be flexibly adjusted according to the light source characteristics of the optical device, the material of the lens 4, and other design requirements, and is not specifically limited here.

[0046] In this embodiment, the reflector cup 32 is a hollow truncated square with a rectangular cross-section. Correspondingly, the lens inner grid 42 is a truncated square with a rectangular cross-section. The circumferential side surfaces of the lens inner grid 42 form a first reflecting surface 421. For the truncated square lens inner grid 42, all four circumferential side surfaces are first reflecting surfaces 421. Multiple reflector cups 32 are arranged continuously, and correspondingly, multiple truncated square lens inner grids 42 are arranged continuously. The first reflecting surface 421 of any truncated square lens inner grid 42 and the first reflecting surface 421 of the adjacent truncated square lens inner grid 42 are sandwiched to form a V-shaped groove 43.

[0047] In some embodiments, the reflector 32 can also be a hollow truncated triangular prism, and correspondingly, the lens inner grid 42 is a truncated triangular prism, with all three circumferential sides of the lens inner grid 42 of the truncated triangular prism serving as first reflecting surfaces 421. Multiple reflectors 32 are arranged consecutively, and correspondingly, multiple truncated triangular prism lens inner grids 42 are arranged consecutively, with the first reflecting surface 421 of any one truncated triangular prism lens inner grid 42 and the first reflecting surface 421 of the adjacent truncated triangular prism lens inner grid 42 forming a V-shaped groove 43.

[0048] In some embodiments, the reflector 32 can also be a hollow truncated square with a trapezoidal cross-section, and correspondingly, the lens inner grid 42 can also be a truncated square with a trapezoidal cross-section. The lens inner grids 42 can be arranged continuously, and the first reflecting surface 421 of any one lens inner grid 42 and the first reflecting surface 421 of the adjacent lens inner grid 42 can be sandwiched to form a V-shaped groove 43. The shapes of the reflector 32 and the lens inner grid 42 are not specifically limited here.

[0049] In some embodiments, the reflector 32 can be replaced with a total internal reflection lens. A total internal reflection lens can significantly reduce light loss, achieve efficient total internal reflection, precisely control the direction of light propagation, effectively improve light efficiency, and reduce glare interference. In still other embodiments, the reflector 32 can be replaced with a convex lens. A convex lens, through its refractive properties, converges diverging light rays into parallel light or a beam at a specific angle, enhancing light concentration and illumination distance.

[0050] In some embodiments, the lens body 41 can be replaced with a convex lens. A convex lens, by virtue of its light-convexity-convexity-convexity-convexity-convexity-light-convexity-light-convexity-light-convexity-light-convexity-light-convexity-light-convexity-light-convexity-light-convexity-light-reflection-accurately-reflect-light-at-multi-angles through a precise prism structure, effectively improving the uniformity of light distribution and reducing glare. In still other embodiments, the lens body 41 can be replaced with a diffuser plate. A diffuser plate utilizes the principle of diffuse reflection to evenly disperse concentrated light, eliminating glare and creating a soft and comfortable lighting environment.

[0051] like Figures 3-5As shown, the outer contour of the inner lens grid 42 on the side opposite to the lens body 41 completely covers the light outlet 322 of the corresponding reflector 32. This ensures that all light reflected from the reflector 32 enters the corresponding inner lens grid 42, preventing light scattering or escape, minimizing light loss, and improving light utilization. Simultaneously, this design makes the light transmission path more regular, helping the lens 4 to efficiently converge and control the light, resulting in a more uniform light distribution and effectively improving the illumination effect and performance of the optical device.

[0052] Specifically, the inner grid 42 of the lens has a groove 422 on the side facing the reflector 32, and the opening boundary of the groove 422 overlaps with the opening boundary of the corresponding reflector 32. This overlapping structure helps to eliminate gaps in light transmission, reduce dark area breaks between adjacent reflectors 32, and make the distribution of light on the surface of the lens 4 more coherent and uniform, thereby significantly improving the illumination quality of the optical device.

[0053] like Figures 2-5 As shown, in this embodiment, the fixing member 31 is provided with an annular support protrusion 311. The circumferential direction of the lens body 41 facing the reflector cup 32 can be engaged with the annular support protrusion 311. The annular support protrusion 311 provides stable support for the lens 4, ensuring that light can be accurately reflected by the reflector cup 32 to the corresponding area of ​​the lens 4, improving the overall stability and light transmission efficiency of the optical device, and optimizing the lighting effect.

[0054] In this embodiment, as Figure 6 As shown, a plurality of first microstructures 4211 are disposed on the first reflective surface 421, and the plurality of first microstructures 4211 are arranged at intervals along a first preset direction on the first reflective surface 421. On the one hand, the plurality of first microstructures 4211 arranged at intervals along the first preset direction on the first reflective surface 421 can reflect and refract light multiple times, effectively changing the direction of light propagation and making the light distribution more uniform. On the other hand, the plurality of first microstructures 4211 can also reduce light loss during the reflection process, improve light utilization, and further eliminate the unevenness of brightness on the surface of lens 4, avoid visual glare, and significantly optimize the illumination effect and user experience of the optical device.

[0055] In this embodiment, the first preset direction is defined as the extension direction of the first reflective surface 421 and / or the circumferential direction of the first reflective surface 421, so that the first microstructure 4211 covers the entire first reflective surface 421. This arrangement follows the initial reflection path of the light, guides the light to undergo multiple refractions and reflections along the direction away from the lens body 41, effectively fills the blank area of ​​the light, eliminates the dark area discontinuity, improves the uniformity of light distribution, reduces light loss, optimizes the overall illumination effect of the optical device, and brings a more comfortable visual experience.

[0056] In this embodiment, multiple first microstructures 4211 are arranged in a closely spaced array, seamlessly connected and continuously extended. By constructing a nearly complete optical control surface, dense and coherent reflection and refraction of light are achieved, maximizing the uniformity and coherence of light distribution, reducing light escape and loss, and optimizing the illumination performance of the optical device.

[0057] In this embodiment, the first microstructure 4211 is a raised structure. In other embodiments, the first microstructure 4211 may also be a recessed structure; or, among multiple first microstructures 4211, some are raised structures and the rest are recessed structures, which is not specifically limited here.

[0058] In some embodiments, multiple first microstructures 4211 are arranged in an array at intervals on the first reflective surface 421. The regular array layout allows the first reflective surface 421 to precisely control the direction of light, achieving a uniform and stable optical effect. In other embodiments, multiple first microstructures 4211 are arranged randomly on the first reflective surface 421, or multiple first microstructures 4211 are arranged in a gradient on the first reflective surface 421. The arrangement method is not specifically limited here.

[0059] In other embodiments, an electroplated layer is provided on the first reflective surface 421. On the one hand, the electroplated layer on the first reflective surface 421 can significantly improve the smoothness and reflectivity of the first reflective surface 421, effectively reducing light loss during the reflection process and enabling light to undergo total internal reflection with higher efficiency. On the other hand, the high-reflectivity electroplated layer helps to improve the concentration and uniformity of light, reduce glare and ghosting phenomena, optimize the light output effect of the optical device, and provide a brighter, more comfortable, and higher-quality lighting experience.

[0060] like Figure 6 As shown, a plurality of second microstructures 4221 are disposed on the side of the lens inner grid 42 opposite to the lens body 41, and the plurality of second microstructures 4221 are arranged at intervals along a second preset direction on the lens inner grid 42. On the one hand, the plurality of second microstructures 4221 convert direct strong light into soft diffused light by reflecting and scattering light multiple times, which can avoid the phenomenon of excessive brightness or glare caused by excessive focus of light, and effectively solve the glare problem. On the other hand, the second microstructures 4221 blur the light source 22, hide the light source 22, and the user cannot directly observe the internal light source 22, which significantly improves the light quality of the optical device.

[0061] In this embodiment, the second preset direction is defined as the length direction and / or width direction of the lens inner grid 42, so that the second microstructure 4221 fills the entire side of the lens inner grid 42 facing the reflector cup 32. This design can eliminate the brightness difference that may be caused by light transmission in the elongated lens inner grid 42, so that the light forms a continuous and soft illumination effect along the length direction, further improving the overall illumination quality and visual experience of the optical device.

[0062] Specifically, multiple second microstructures 4221 are densely and seamlessly distributed on the bottom wall of the recess 422 of the lens grid 42, forming a dense array structure that completely covers the bottom wall of the recess 422. Through the seamless connection of the boundaries of adjacent second microstructures 4221, it is ensured that every area of ​​the bottom wall of the recess 422 is equipped with a light control unit, thereby realizing full-area, no-dead-angle optical processing of light transmitted through the recess 422, providing a reliable structural basis for precise control of the light propagation path and distribution pattern.

[0063] In this embodiment, the second microstructure 4221 is a raised structure. In other embodiments, the second microstructure 4221 may also be a recessed structure; or, among multiple second microstructures 4221, some are raised structures and the rest are recessed structures, which is not specifically limited here.

[0064] In some embodiments, multiple second microstructures 4221 are arranged in an array at intervals on the bottom wall of the groove 422. The regular array layout allows the bottom wall of the groove 422 to precisely control the direction of light, achieving a uniform and stable optical effect. In other embodiments, multiple second microstructures 4221 are arranged randomly on the bottom wall of the groove 422, or multiple second microstructures 4221 are arranged in a gradient on the bottom wall of the groove 422. The specific arrangement method is not limited here.

[0065] like Figures 2-5 As shown, the inner surface of the reflector 32 is the second reflective surface 321. Multiple third microstructures 3211 are provided on the second reflective surface 321, and these microstructures are arranged at intervals along a third preset direction. On one hand, the multiple third microstructures 3211 arranged at intervals along the third preset direction on the second reflective surface 321 of the reflector 32 effectively disperse and redistribute light through multiple reflections and refractions, preventing light from concentrating in a certain area. This prevents localized over-brightness or dark area fragmentation on the outer surface of the lens body 41, ensuring uniform light distribution. On the other hand, the precise control of the light propagation trajectory by the third microstructures 3211 can eliminate excess light caused by differences in light reflection paths, reduce ghosting when illuminating objects, and improve the imaging clarity and illumination quality of the optical device.

[0066] In this embodiment, the third preset direction is defined as the extension direction of the inner surface of the reflector 32 and / or the circumferential direction of the reflector 32, so that the third microstructure 3211 covers the entire inner surface of the reflector 32. This effectively avoids the problem of local over-brightness or dark area discontinuity on the outer surface of the lens body 41 caused by light concentration, significantly reduces ghosting when illuminating objects, and greatly improves the illumination uniformity of the optical system.

[0067] In this embodiment, multiple third microstructures 3211 are closely arranged so that they fully cover the second reflective surface 321. This full-surface coverage design ensures that when light is incident at any position on the second reflective surface 321, it can interact with the third microstructures 3211, achieving precise control of the light propagation path across the entire area without dead angles, and providing comprehensive protection for optimizing light distribution and improving optical performance.

[0068] In this embodiment, the third microstructure 3211 is a protruding structure. In other embodiments, the third microstructure 3211 may also be a recessed structure; or, among multiple third microstructures 3211, some are protruding structures and the rest are recessed structures, which is not specifically limited here.

[0069] In some embodiments, multiple third microstructures 3211 are arranged in an array at intervals on the second reflective surface 321. The regular array layout allows the second reflective surface 321 to precisely control the direction of light, achieving a uniform and stable optical effect. In other embodiments, multiple third microstructures 3211 are arranged randomly on the second reflective surface 321, or multiple third microstructures 3211 are arranged in a gradient on the second reflective surface 321. The arrangement method is not specifically limited here.

[0070] In summary, as Figure 5 As shown, the light propagation process of the optical device is roughly as follows: Light emitted from the continuously and uniformly arranged light sources 22 on the mounting component 21, and reflected by the second reflecting surface 321 of the reflector 32, part of the light is projected onto the inner surface of the lens inner grid 42, forming a uniform base light layer; another part of the light undergoes total internal reflection at the first reflecting surface 421 of the lens inner grid 42, cleverly filling the illumination blind spot between two adjacent reflectors 32, ensuring uniform light coverage. In addition, light emitted directly from the light source 22 without contacting the reflector 32 and the second reflecting surface 321 can also uniformly illuminate the inner surface of the lens inner grid 42 with good angle and distribution characteristics. The multi-path light transmission mechanism works together to effectively eliminate dark areas and light intensity differences, bringing users a comfortable and uniform lighting experience.

[0071] like Figure 1As shown, the side of lens 4 facing away from reflector 32 is a smooth plane. On one hand, this smooth plane makes the light output more regular, improves the consistency of the overall light effect, ensures that the light uniformly covers the target area, and reduces ghosting when illuminating objects. On the other hand, the smooth surface design also facilitates cleaning and maintenance, reduces the impact of dust and stains on light propagation, and maintains the good lighting performance and visual effect of the optical device.

[0072] In other embodiments, a fifth microstructure may also be provided on the outer surface of the lens body 41. The fifth microstructure converts direct light into diffused light by changing the refraction angle and propagation path of the light, effectively reducing the glare and interference of glare with the human eye, and improving lighting comfort. Optionally, the fifth microstructure may be a raised structure or a recessed structure; no specific limitation is made here.

[0073] like Figure 5 As shown, in this embodiment, the bottom wall of the groove 422 facing the interior of the reflector cup 32 is a raised structure, causing the light to undergo multiple reflections and refractions within the groove 422, thus scattering and concentrating the light and preventing uneven brightness on the surface of the lens body 41. This results in a more uniform and higher-quality illumination effect after the light passes through the inner frame 42 of the lens and the lens body 41, optimizing the overall light efficiency and user experience of the optical device. In other embodiments, the outer surface of the lens body 41 may also be a raised structure, and the bottom wall of the groove 422 facing the interior of the reflector cup 32 may also be a flat surface; no specific limitations are made here.

[0074] Figure 1 , Figures 3-4 As shown, the optical device also includes an anti-glare shield 5, which is connected to the end of the lens 4 away from the reflective assembly 3. The anti-glare shield 5 is used to increase the anti-glare angle of the light. By subjecting the emitted light to secondary confinement and diffusion, the anti-glare shield 5 can suppress the direct emission of high-angle light, avoid the glare caused by direct strong light, significantly reduce the interference of light on the human eye, and improve visual comfort.

[0075] It is worth noting that the anti-glare angle is the angle measured outward from the central axis of the optical device, based on the surface area of ​​the light-emitting element 22. It is a specific range of angles defined to reduce or avoid discomfort and visual interference caused by glare to the human eye. Within this range, the light emitted by the light source 22 is specially designed or processed so that the human eye will not directly see the excessively bright light source 22 in the normal viewing direction, thereby reducing the impact of glare and providing a more comfortable and uniform lighting environment. There is no fixed standard for the anti-glare angle. Indoor lighting requires an anti-glare angle between 30 and 60 degrees, while road lighting requires an anti-glare angle between 45 and 70 degrees. The anti-glare shield 5 can be designed according to the actual lighting scenario and the requirements of relevant standards and specifications; no specific limitations are made here.

[0076] In this embodiment, the anti-glare shield 5 is a U-shaped shield. The inner ring of the U-shaped shield is circumferentially connected to the lens body 41, and the outer ring of the U-shaped shield is connected to the housing 1. On the one hand, the anti-glare shield 5 connects the lens body 41 and the housing 1 with a U-shaped structure. By increasing the anti-glare angle, it effectively blocks high-angle glare from directly hitting the eyes, significantly reduces the glare of strong light, optimizes the light distribution, makes the light more uniform and soft, and effectively relieves visual fatigue. On the other hand, the U-shaped anti-glare shield 5 can perform secondary reflection and refraction of the light emitted from the edge of the lens body 41, reducing light pollution and light loss, and improving the utilization rate of lighting light. In addition, the U-shaped shield can also effectively prevent dust from entering the interior of the housing 1, avoid dust from adhering to the light source component 2 or the reflector component 3, reduce the risk of failure caused by dust accumulation, and provide long-term dust protection for the internal components of the optical device.

[0077] In other embodiments, anti-glare shields 5 can be provided only on both sides of the lens body 41, which can specifically suppress stray light and glare in both directions. Compared with the full circumference setting, the anti-glare shields 5 on both sides can reduce material costs and assembly complexity.

[0078] Figure 4 , Figure 6 and Figure 8 As shown, a fourth microstructure 51 is provided on the inner surface of the anti-glare shield 5. The fourth microstructure 51 can refract and scatter light multiple times, further dispersing high-angle emitted light, effectively increasing the anti-glare angle, and reducing the intensity of glare caused by direct light. At the same time, by optimizing the light propagation path, it reduces concentrated reflection and diffuse reflection of light, making the light distribution more uniform and soft, avoiding visual discomfort caused by glare, and comprehensively improving the lighting comfort and user experience of the optical device.

[0079] Figure 4 , Figure 6 and Figure 8 As shown, in this embodiment, the inner surface of the anti-glare shield 5 faces the interior of the housing 1, and the fourth microstructure 51 provided on the inner surface of the anti-glare shield 5 is a diamond-cut structure. On the one hand, the diamond-cut structure suppresses glare leakage from the side of the anti-glare shield 5, significantly reducing glare intensity and avoiding the glare problem caused by concentrated light. On the other hand, the diamond-cut structure can accurately reflect and refract light from multiple angles, effectively adjusting the light propagation path through a prism-like beam splitting effect, dispersing direct light into soft diffused light, improving the uniformity of light distribution, and simultaneously increasing the high light transmittance of the lens body 41.

[0080] In some embodiments, the anti-glare shield 5 has a raised structure on its inner surface facing the inside of the housing 1, which can effectively disrupt the light propagation path and reduce the glare intensity. In other embodiments, the anti-glare shield 5 has a recessed structure on its inner surface facing the inside of the housing 1, which can effectively change the light propagation trajectory and significantly reduce the glare intensity. The microstructures provided on the inner surface of the anti-glare shield 5 facing the inside of the housing 1 are not specifically limited here.

[0081] In this embodiment, the lens 4 and the anti-glare shield 5 are an integrated structure. On the one hand, this simplifies the assembly process, effectively reduces assembly steps and gaps between components, enhances the stability of component connections, and improves the overall vibration resistance of the optical device. On the other hand, it eliminates the assembly errors of traditional split structures, resulting in better optical effects and reducing stray light problems caused by light refraction between different optical components, as well as the reduction in illumination efficiency.

[0082] In other embodiments, the lens 4 and the anti-glare cover 5 adopt a separate design. Their independent structure makes it easy to select appropriate materials, processes and shapes according to different lighting scenarios and functional requirements. At the same time, the separate design also makes component replacement and maintenance more convenient, reduces maintenance costs, and extends the overall service life of the optical device. Users can also match different styles of lens 4 and anti-glare cover 5 according to their preferences to achieve a personalized lighting experience.

[0083] like Figures 6-8 As shown, the lens body 41 is provided with a tongue 411, and the fixing member 31 is provided with a hole 312. The tongue 411 can be inserted into the hole 312 and engage with it. On the one hand, this ensures the positional accuracy of the lens inner grid 42 and the reflector cup 32, ensuring that light accurately enters the lens inner grid 42 after being reflected by the reflector cup 32, reducing light loss, improving light uniformity, and further optimizing the overall performance and reliability of the optical device. On the other hand, it simplifies the installation process, improves assembly efficiency, and enables precise positioning and stable connection between the lens 4 and the reflector assembly 3, effectively preventing relative displacement during the assembly, transportation, and use of the optical device.

[0084] In this embodiment, the anti-glare shield 5 is made of transparent material. On the one hand, the transparent material of the anti-glare shield 5 effectively increases the anti-glare angle and reduces glare, while minimizing light obstruction and avoiding light loss due to poor light transmittance, ensuring efficient light transmission. On the other hand, the transparent anti-glare shield 5 allows the light to maintain its original brightness and color characteristics, without affecting the overall lighting effect and light distribution uniformity of the optical device.

[0085] In addition, the transparent anti-glare cover 5, combined with its internal diamond-cut structure, not only gives the optical device a simple and smooth overall appearance, but also perfectly blends practical anti-glare function with artistic beauty with the unique dazzling and dynamic sparkling effect of the diamond-cut structure. This design effectively enhances the visual appeal of the optical device.

[0086] It is worth noting that some of the light will be reflected by mirrors on the light-incident surface of the transparent anti-glare shield 5 before being emitted; another part of the light will enter the interior of the anti-glare shield 5 from the light-incident surface and be reflected once or multiple times by the diamond-faceted structure, and then emitted a second time from the light-incident surface of the anti-glare shield 5, so that the outer surface of the anti-glare shield 5 also has a slightly bright effect. That is, the outer surface of the lens body 41, which emits light continuously and uniformly, serves as the main illumination area and is responsible for focusing the light, while the outer surface of the slightly luminous transparent anti-glare shield 5 serves as the auxiliary illumination area. The diamond-faceted structure reflects light to increase the luminous area and reduce the light intensity per unit area, thereby reducing visual glare.

[0087] In other embodiments, the anti-glare shield 5 can also be black, white, red, green, yellow, etc. The appropriate color of the anti-glare shield 5 can be selected according to the actual application, and no specific limitation is made here.
