Description

Technical Field

[0001] This disclosure relates to the technical field of linear in-ground lights, and in particular to an anti-glare linear in-ground light. Background Technology

[0002] In-ground lights, widely used in urban landscape lighting, architectural outlining, and garden walkway embellishment, occupy an important position in the modern lighting field due to their unique installation method and diverse light and shadow effects. They are typically buried underground, with only the luminous surface exposed, providing necessary functional lighting while seamlessly blending with the surrounding environment to create a unique and captivating nighttime atmosphere.

[0003] Currently available in-ground lights generally have relatively simple anti-glare structures. Most products only use basic anti-glare methods such as simple light shields or frosted glass. Although light shields can block some direct light to a certain extent and reduce the possibility of light directly hitting the eyes, their shape and angle design often lacks specificity and fails to meet the anti-glare requirements of the installation environment. As a result, in actual applications, a large amount of light still passes through the light shield and scatters, thus causing obvious glare to the eyes. Utility Model Content

[0004] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide an anti-glare linear in-ground light with improved anti-glare effect.

[0005] The purpose of this disclosure is achieved through the following technical solution: An anti-glare linear in-ground light includes a cover plate, an anti-glare structure, and a lamp housing.

[0008] In one embodiment, the grille assembly further includes a first fixing clip and a second fixing clip, which are symmetrically arranged on the top of the trapezoidal grille along the length extension direction of the lamp housing, and the optical diffusion film abuts against the first fixing clip and the second fixing clip respectively.

[0009] In one embodiment, the lamp housing further includes a third limiting member and a fourth limiting member, and the light-transmitting sub-assembly further includes a first snap-fit ​​member and a second snap-fit ​​member. One end of the first snap-fit ​​member is snapped into the third limiting member, and the other end of the first snap-fit ​​member is connected to the light-transmitting member. One end of the second snap-fit ​​member is snapped into the fourth limiting member, and the other end of the second snap-fit ​​member is connected to the light-transmitting member.

[0010] In one embodiment, the light-transmitting sub-assembly further includes a first fixing member and a second fixing member, and the light source assembly further includes a light source substrate, the light source substrate having a first fixing through hole and a second fixing through hole, the first fixing member passing through the first fixing through hole, and the second fixing member passing through the second fixing through hole.

[0011] In one embodiment, a plurality of light-emitting elements are spaced apart on the light source substrate along the length extension direction of the light source substrate.

[0012] In one embodiment, the lamp housing further includes a fifth limiting member and a sixth limiting member.

However, this disclosure can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments: like Figures 1 to 8 As shown, an embodiment of the anti-glare linear in-ground light 10 disclosed herein includes a cover plate 100, an anti-glare structure 200, and a light fixture housing 300. The anti-glare structure 200 is disposed inside the light fixture housing 300, and the cover plate 100 covers the light fixture housing 300. The anti-glare structure 200 includes a light source assembly 210, a light transmission assembly 220, a grid assembly 230, and an optical diffusion film 240 arranged in sequence. The light source assembly 210 is disposed near the bottom of the light fixture housing 300, and the optical diffusion film 240 is disposed near the bottom of the light fixture housing 300. Near the cover plate 100, the light-transmitting component 220 includes multiple light-transmitting sub-components 221, each light-transmitting sub-component 221 includes multiple light-transmitting elements 2211, each light-transmitting element 2211 includes a curved reflective element 2211A and a conical light-incident element 2211B, the curved reflective element 2211A is disposed above the conical light-incident element 2211B, the conical light-incident element 2211B has a light-transmitting through hole 2201, the light-transmitting through hole 2201 is connected to the interior of the curved reflective element 2211A.

[0023] The grille assembly 230 includes multiple grille sub-assemblies 231, each grille assembly 231 includes multiple trapezoidal grilles 2311, each trapezoidal grille 2311 has a light-transmitting slot 2301, the light-emitting surface of the curved reflector 2211A abuts against the trapezoidal grille 2311, the optical diffusion film 240 is disposed above the grille assembly 230, and the light source assembly 210 is disposed below the conical light-incident element 2211B. The light source assembly 210 includes multiple light-emitting elements 211, each light-emitting element 211 corresponding to a light-transmitting hole 2201.

[0024] In this embodiment, when the light source assembly 210 is powered on, multiple light-emitting elements 211 begin to emit light. Since each light-emitting element 211 corresponds to a light-transmitting aperture 2201, the light first precisely enters the conical photosensitive element 2211B. The conical structure of the conical photosensitive element 2211B effectively guides the light to the light-transmitting aperture 2201, avoiding significant light loss during transmission and improving light utilization. Moreover, the conical structure itself further focuses the light, making the light emitted from the light-transmitting aperture 2201 more concentrated. After emitting from the light-transmitting aperture 2201, the light enters the interior of the curved reflective element 2211A. Because the curved shape of the curved reflective element 2211A increases the light reflection area, the light can be reflected and propagated over a larger spatial range, thus allowing the light to be distributed more evenly. Specifically, the curved reflective element 2211A also performs preliminary light diffusion processing. By changing the direction of light propagation, the originally concentrated light is dispersed, effectively reducing the glare effect that direct light may produce, making the light felt by the user softer and more comfortable, and avoiding visual discomfort caused by glare.

[0025] Furthermore, the light, after being processed by the curved reflector 2211A, continues to propagate forward and reaches the grille assembly 230. The light-transmitting slots 2301 in each trapezoidal grille 2311 of the grille assembly 230 become channels for further light propagation. The light-transmitting slots 2301 not only allow light to pass smoothly but also, through the trapezoidal shape of the grille 2311, perform secondary diffusion and distribution of the light. The special trapezoidal structure causes the light to be reflected and refracted at different angles as it passes through, further diffusing the light and making the light emitted from the grille assembly 230 softer and more evenly distributed. Then, the light emitted from the grille assembly 230 passes through the optical diffusion film 240, which redistributes the light in various directions by scattering it, thereby achieving a uniform light distribution effect. This makes the light output from the cover plate 100 for the anti-glare linear in-ground light 10 more uniform.

[0026] The aforementioned anti-glare linear in-ground light 10 features a tapered light-incident element 2211B whose tapered structure effectively guides light into the light-transmitting aperture 2201, preventing significant light loss during transmission and improving light utilization. The curved reflector element 2211A initially diffuses the light, the grille assembly 230 further diffuses and distributes the light, and the optical diffusion film 240 ultimately redistributes the light in all directions. Through multiple processes, the light output becomes more uniform. The curved reflector element 2211A initially reduces glare by changing the direction of light propagation, while the grille assembly 230 and optical diffusion film 240 further diffuse the light, making it softer and the light spot more uniform and continuous, thereby effectively reducing glare for the user.

[0027] like Figure 6 As shown, in one embodiment, the lamp housing 300 includes a first limiting member 310 and a second limiting member 320. The first limiting member 310 has a first limiting through groove 3101, and the second limiting member 320 has a second limiting through groove 3201. Please refer to the following: Figure 5 The grille assembly 231 also includes a first limiting boss 2312 and a second limiting boss 2313. The first limiting boss 2312 and the second limiting boss 2313 are symmetrically arranged on the side wall of the trapezoidal grille 2311 along the length extension direction of the lamp housing 300. One end of the first limiting boss 2312 is engaged in the first limiting through groove 3101, and the other end of the first limiting boss 2312 is connected to the trapezoidal grille 2311. One end of the second limiting boss 2313 is engaged in the second limiting through groove 3201, and the other end of the second limiting boss 2313 is connected to the trapezoidal grille 2311. In this embodiment, during the assembly of the anti-glare linear in-ground light 10, simply aligning the first limiting boss 2312 with the first limiting through groove 3101 and the second limiting boss 2313 with the second limiting through groove 3201 and pushing them in achieves rapid positioning of the grille assembly 231, avoiding uneven light distribution caused by installation position deviations. Simultaneously, this improves the assembly efficiency of the anti-glare linear in-ground light 10, reduces installation and debugging time and costs, and enhances the structural stability of the anti-glare linear in-ground light 10.

[0028] like Figure 2 and Figure 5As shown, in one embodiment, the grille assembly 231 further includes a first fixing clip 2314 and a second fixing clip 2315. The first fixing clip 2314 and the second fixing clip 2315 are symmetrically arranged on the top of the trapezoidal grille 2311 along the length extension direction of the lamp housing 300, and the optical diffusion film 240 abuts against the first fixing clip 2314 and the second fixing clip 2315 respectively. In this embodiment, the first fixing clip 2314 and the second fixing clip 2315 provide a stable and precise fixing position for the optical diffusion film 240. When the optical diffusion film 240 is placed above the grille assembly 230, its edges only need to abut against the first fixing clip 2314 and the second fixing clip 2315 respectively to achieve quick and accurate positioning and installation, thereby ensuring that the optical diffusion film 240 will not shift or loosen during the operation of the lamp, and thus ensuring that the light can be emitted uniformly and stably from the cover plate 100 after passing through the optical diffusion film 240.

[0029] like Figure 2 , Figure 4 and Figure 6 As shown, in one embodiment, the lamp housing 300 further includes a third limiting member 330 and a fourth limiting member 340, and the light-transmitting sub-assembly 221 further includes a first snap-fit ​​member 2214 and a second snap-fit ​​member 2215. One end of the first snap-fit ​​member 2214 is snapped into the third limiting member 330, and the other end of the first snap-fit ​​member 2214 is connected to the light-transmitting member 2211. One end of the second snap-fit ​​member 2215 is snapped into the fourth limiting member 340, and the other end of the second snap-fit ​​member 2215 is connected to the light-transmitting member 2211. In this embodiment, the snap-fit ​​cooperation between the first snap-fit ​​member 2214 and the third limiting member 330, and between the second snap-fit ​​member 2215 and the fourth limiting member 340, provides precise positioning of the light-transmitting sub-assembly 221 within the lamp housing 300. Specifically, during the assembly of the anti-glare linear in-ground light 10, simply aligning the first snap-fit ​​component 2214 with the third limiting component 330 and the second snap-fit ​​component 2215 with the fourth limiting component 340 and completing the snap-fit ​​action allows for quick and accurate determination of the installation position of the light-transmitting component 221. This avoids changes in the light propagation path caused by installation position deviations, thus preventing any impact on the uniform distribution of light and the anti-glare effect. Furthermore, the above snap-fit ​​method ensures that the light-transmitting component 221 will not shift or loosen during the operation of the light fixture, maintaining its relative positional stability with other components such as the light source component 210 and the grille component 230, thereby ensuring that the anti-glare structure 200 can achieve its anti-glare effect.

[0030] like Figures 2 to 4As shown, in one embodiment, the light-transmitting sub-assembly 221 further includes a first fixing member 2212 and a second fixing member 2213, and the light source assembly 210 further includes a light source substrate 212. The light source substrate 212 has a first fixing through hole 2101 and a second fixing through hole 2102. The first fixing member 2212 passes through the first fixing through hole 2101, and the second fixing member 2213 passes through the second fixing through hole 2102. In this embodiment, during the assembly process of the anti-glare linear in-ground light 10, by accurately inserting the first fixing member 2212 and the second fixing member 2213 into the corresponding fixing through holes, the relative positions between the two can be quickly and accurately determined, avoiding changes in the light propagation path caused by installation position deviations, and ensuring that the light can accurately enter the light-transmitting sub-assembly 221. Since the first fixing member 2212 and the second fixing member 2213 accurately position and securely connect the light-transmitting sub-assembly 221 and the light source assembly 210, the light emitted from the light source assembly 210 can accurately propagate according to the designed light path.

[0031] like Figure 2 and Figure 3 As shown, in one embodiment, multiple light-emitting elements 211 are spaced apart on the light source substrate 212 along its length. In this embodiment, the spaced-apart light-emitting elements 211 optimize the light coverage of the entire illumination area in terms of light distribution uniformity. Specifically, since the light-emitting elements 211 are not concentrated but evenly spaced along the length of the light source substrate 212, light can be emitted simultaneously from multiple different positions. After the light is controlled by the light-transmitting component 220, the grille component 230, and the optical diffusion film 240, it can be more evenly distributed throughout the illumination space. Compared with a concentrated light source, this avoids the situation where the light is too strong in some areas and too weak in others, effectively eliminating lighting dead zones and providing users with a more comfortable and uniform visual environment.

[0032] like Figure 3 and Figure 6As shown, in one embodiment, the lamp housing 300 further includes a fifth limiting member 350 and a sixth limiting member 360. The fifth limiting member 350 and the lamp housing 300 form a third limiting through groove 3501, and the sixth limiting member 360 and the lamp housing 300 form a fourth limiting through groove 3601. The light source substrate 212 passes through the third limiting through groove 3501 and the fourth limiting through groove 3601 respectively. In this embodiment, the light source substrate 212 passes through the third limiting through groove 3501 and the fourth limiting through groove 3601 respectively, providing a precise installation position for the light source assembly 210 within the lamp housing 300. During assembly, simply inserting the light source substrate 212 accurately into these two limiting through grooves quickly completes the positioning of the light source assembly 210, avoiding the installation position deviation problem that may occur in traditional installation methods. This ensures that the light emitted from the light source can accurately enter the subsequent optical control structure, guaranteeing the accuracy of the light propagation path and maintaining good anti-glare effect and lighting quality.

[0033] like Figure 5 and Figure 6 As shown, in one embodiment, the first limiting member 310 is further provided with a fifth limiting through groove 3102, and the second limiting member 320 is further provided with a sixth limiting through groove 3202. A portion of the grille assembly 231 is respectively housed in the fifth limiting through groove 3102 and the sixth limiting through groove 3202. In this embodiment, the trapezoidal grille 2311 is partially housed in the fifth limiting through groove 3102 and the sixth limiting through groove 3202, providing a more precise and stable positioning for the grille assembly 231 within the lamp housing 300. During assembly, the operator only needs to align the corresponding portion of the grille assembly 231 with the fifth limiting through groove 3102 and the sixth limiting through groove 3202 to quickly and accurately complete the installation of the grille assembly 231. Compared to traditional fuzzy positioning or non-positioning installation methods, this greatly reduces potential errors during installation and avoids inaccurate relative positions between the grille assembly 231 and other components due to installation position deviations, thereby affecting the light propagation path and lighting effect.

[0034] like Figure 4 , Figure 5 and Figure 7As shown, in one embodiment, the bottom contour of the trapezoidal grille 2311 is adapted to the light-emitting surface of the curved reflective element 2211A. In this embodiment, the bottom contour of the trapezoidal grille 2311 is adapted to the light-emitting surface of the curved reflective element 2211A. In this embodiment, when light is emitted from the curved reflective element 2211A, because its bottom contour perfectly matches the bottom of the grille, the light can enter the light-transmitting slot 2301 of the trapezoidal grille 2311 without obstruction and with precision. This avoids scattering or reflection loss of light in the transition area between the two, thereby optimizing the propagation of light, ensuring that the light can propagate according to the designed light path, and thus improving the utilization rate of light.

[0035] like Figure 5 and Figure 8 As shown, in one embodiment, the cover plate 100 has a light-emitting slot 1001, which extends along the length of the cover plate 100. In this embodiment, the light-emitting slot 1001 extends along the length of the cover plate 100, thus providing a clear guiding channel for the light emitted from the grille assembly 230. After secondary diffusion and distribution in the light-emitting slot 2301 of the grille assembly 230, the light can continue to propagate in a preset direction after entering the light-emitting slot 1001. Since the length extension direction of the light-emitting slot 1001 is consistent with that of the cover plate 100, the light can be emitted more evenly along this direction, further optimizing the distribution of light in the entire lighting area. Compared with the case without the light-emitting slot 1001, the light can cover the lighting space more orderly, avoiding the phenomenon of excessive concentration or uneven dispersion of light after exiting the lamp, making the light distribution in the entire lighting area more uniform and soft, thereby providing users with a better visual experience.

[0036] Compared with the prior art, this disclosure has at least the following advantages: The aforementioned anti-glare linear in-ground light 10 features a tapered light-incident element 2211B whose tapered structure effectively guides light into the light-transmitting aperture 2201, preventing significant light loss during transmission and improving light utilization. The curved reflector element 2211A initially diffuses the light, the grille assembly 230 further diffuses and distributes the light, and the optical diffusion film 240 ultimately redistributes the light in all directions. Through multiple processes, the light output becomes more uniform. The curved reflector element 2211A initially reduces glare by changing the direction of light propagation, while the grille assembly 230 and optical diffusion film 240 further diffuse the light, making it softer and the light spot more uniform and continuous, thus effectively reducing glare for the user.

[0037] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
