Description

Technical Field

[0001] This utility model relates to the field of lighting structure technology, and in particular to a three-sided anti-glare grille and its in-ground lamp. Background Technology

[0002] Recessed lighting fixtures such as in-ground lights and wall lights are widely used in landscape lighting, architectural decoration, and road guidance. One of their core functions is to provide necessary lighting while avoiding glare interference to pedestrians, drivers, or residents, ensuring visual comfort and public safety. Currently, these types of lights generally use a grille structure to achieve anti-glare. Traditional grilles aim to achieve uniform light diffusion or shielding in a 360-degree direction, but their anti-glare effect has significant limitations. In many specific applications, such as illuminating only specific areas of walls or floors, or where it is necessary to strictly prevent light from shining towards sensitive areas such as roads and windows, existing grille technology cannot achieve highly directional light path control. Utility Model Content

[0003] The purpose of this invention is to propose a three-sided anti-glare grille and its in-ground light, which can guide and constrain light to be output mainly in a preset direction, effectively blocking glare light in a specific direction, thereby achieving three-sided anti-glare.

[0004] To achieve this objective, the present invention adopts the following technical solution: A three-sided anti-glare grille includes a grille body and a frame. The grille body includes a plurality of horizontal and vertical blades arranged in a crisscross pattern on the inner wall of the frame. The horizontal blades are perpendicular to the horizontal plane A, and the vertical blades are inclined to the horizontal plane A. The vertical blades form an angle B with the vertical direction.

[0005] To further clarify, the included angle B is in the range of 3-30 degrees.

[0006] To further explain, the top periphery of the frame is provided with an outwardly extending mounting ring.

[0007] An in-ground light includes the aforementioned grille, embedded parts, lamp body, light source, optical elements, and light-emitting plate; The lamp body is disposed within the embedded part, and the lamp body has a mounting cavity. The light source and optical element are both fixed within the mounting cavity, and the optical element is located above the light source. The grille is located above the optical element, and the light-emitting plate is fixed above the lamp body. The light-emitting plate is located above the grille.

[0008] To further explain, it also includes a face ring, the outer periphery of which abuts against the face ring, and the face ring covers the opening of the embedded part.

[0009] To further explain, the inner wall of the lamp body is provided with an annular mounting step, and the mounting ring of the frame is fixed on the mounting step.

[0010] To further explain, the lamp body has an annular glue groove inside, the glue groove is filled with glue, and the light-emitting plate is fixed above the glue groove by the glue.

[0011] To further explain, the bottom of the lamp body is provided with a first through hole that communicates with its mounting cavity, and a fastener is provided in the first through hole.

[0012] To further explain, the bottom of the lamp body is provided with a second through hole that communicates with its mounting cavity, and a waterproof connector is provided in the second through hole.

[0013] To further explain, the outer wall of the lamp body is provided with several convex ring structures, the convex ring structures are arranged horizontally, and the several convex ring structures are arranged at intervals in the vertical direction.

[0014] The technical solution provided by this utility model can include the following beneficial effects: With the above configuration, the grille has a three-sided anti-glare effect. Specifically, the first anti-glare surface is formed by the front surfaces of all the vertical horizontal blades, mainly blocking direct and scattered glare from the horizontal direction parallel to the blade plane, such as an axial direction. The second and third anti-glare surfaces are formed by the front surfaces of all the inclined vertical blades and the side surfaces formed by their intersection with the horizontal blades. Because the vertical blades have an angle B with the vertical direction, their front surfaces are specifically designed to intercept incident light from a specific inclined direction (such as at a low angle to the horizontal plane); while the local triangles formed by their intersection with the vertical horizontal blades 111 block the path of light leakage from the intersecting gaps from the sides.

[0015] Applying the aforementioned grille to specific lighting fixtures provides excellent three-sided anti-glare effects. For example, for in-ground lights: light is directed at a high proportion to the wall or target object, scattering almost without waste into the pedestrian's line of sight. For wall lights: light is strictly directed towards the surface or area requiring illumination, effectively avoiding light pollution from the sky or windows. The result is the complete elimination of interfering light to non-target areas, achieving the ideal optical effect of precise illumination of the target area and effective shielding of non-target areas.

[0016] In addition, structurally, the interlacing of the horizontal blades 111 and the vertical blades 112 forms a dense grid support, which greatly enhances the overall structural rigidity and resistance to pressure and deformation of the grid body 11, making it particularly suitable for harsh environments such as underground lights that need to withstand external loads.

Detailed Implementation

[0019] 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.

[0020] like Figure 1-10 As shown, a three-sided anti-glare grille includes a grille body 11 and a frame 12. The grille body 11 includes a plurality of horizontal blades 111 and vertical blades 112 arranged in a crisscross pattern on the inner wall of the frame 12. The horizontal blades 111 are perpendicular to the horizontal plane A, and the vertical blades 112 are inclined to the horizontal plane A. The vertical blades 112 form an angle B with the vertical direction.

[0021] Through the above configuration, the grille has a three-sided anti-glare effect. Specifically, the first anti-glare surface is formed by the front surfaces of all the vertical horizontal blades 111, mainly blocking direct and scattered glare from the horizontal direction parallel to the blade plane, such as an axial direction. The second and third anti-glare surfaces are formed by the front surfaces of all the inclined vertical blades 112 and the side surfaces formed by their intersection with the horizontal blades 111. Because the vertical blades 112 have an angle B with the vertical direction, their front surfaces are specifically designed to intercept incident light from a specific inclined direction (such as at a low angle to the horizontal plane); while the local triangles formed by their intersection with the vertical horizontal blades 111 block the path of light leakage from the intersecting gaps from the sides.

[0022] Applying the aforementioned grille to specific lighting fixtures provides excellent three-sided anti-glare effects. For example, for in-ground lights: light is directed at a high proportion to the wall or target object, scattering almost without waste into the pedestrian's line of sight. For wall lights: light is strictly directed towards the surface or area requiring illumination, effectively avoiding light pollution from the sky or windows. The result is the complete elimination of interfering light to non-target areas, achieving the ideal optical effect of precise illumination of the target area and effective shielding of non-target areas.

[0023] In addition, structurally, the interlacing of the horizontal blades 111 and the vertical blades 112 forms a dense grid support, which greatly enhances the overall structural rigidity and resistance to pressure and deformation of the grid body 11, making it particularly suitable for harsh environments such as underground lights that need to withstand external loads.

[0024] To further explain, the included angle B is in the range of 3-30 degrees. Through the above settings, the optimal anti-glare angle control range is provided, achieving precise optical shielding.

[0025] When the included angle B is near its lower limit (e.g., 3-10 degrees), the tilt of the longitudinal blades is relatively small, minimizing their obstruction of vertically upward light, thus ensuring the basic axial light output efficiency of the luminaire. Simultaneously, it effectively filters out low-angle stray light that deviates slightly from the vertical direction and is most likely to cause direct glare. This range is particularly suitable for scenarios with extremely high vertical illuminance requirements and a long glare control zone.

[0026] When the included angle B is near its upper limit (e.g., 20-30 degrees), the tilting shielding effect of the longitudinal blades is more significant, effectively blocking a larger horizontal component of light. This provides near-absolute lateral glare protection for luminaires installed near eye level (e.g., low-level wall lights, stair tread lights) or where absolute protection of light from sensitive areas (e.g., residential windows, driveways) is required. This preferred range (3-30 degrees) encompasses a continuous range of technologies from "high efficiency" to "high shielding," enabling designers to perform precise parametric design based on specific installation height, target illumination surface, and the direction of vision requiring protection, thereby finding the optimal engineering solution between "light output" and "anti-glare level."

[0027] To further explain, the top periphery of the frame 12 is provided with an outwardly extending mounting ring 121.

[0028] By providing the mounting ring 121, the entire grille can be easily fixed to the lighting fixture for a specific application. For example, in one embodiment, it is applied to an in-ground light, which has a mounting step 32. The grille can be fixed simply by attaching the mounting ring 121 to the mounting step 32 with adhesive.

[0029] An in-ground light includes a grille, an embedded part 2, a light body 3, a light source 4, an optical element 5, and a light-emitting plate 6. The light body 3 is disposed within the embedded part 2, and the light body 3 has a mounting cavity 31. The light source 4 and the optical element 5 are both fixed within the mounting cavity 31, and the optical element 5 is located above the light source 4. The grille is located above the optical element 5. The light-emitting plate 6 is fixed above the light body 3, and the light-emitting plate 6 is located above the grille.

[0030] When the in-ground light is in use, the light emitted by the light source 4 first passes through the optical element 5 (in this embodiment, the optical element 5 is a lens) for initial light distribution and collection, and then through the core grille for final orientation and purification, before being output by the light-emitting plate 6. The in-ground light in this embodiment uses the grille, resulting in excellent three-sided anti-glare effects. For example, with the in-ground light, the light is directed to the wall or target object at a high proportion, scattering almost without waste into the pedestrian's line of sight, while completely eliminating interference light in non-target areas, achieving the ideal optical effect of precise illumination of the target area and effective shielding of non-target areas. Furthermore, structurally, the crisscrossing of the horizontal blades 111 and the vertical blades 112 forms a dense grid support, greatly enhancing the overall structural rigidity and resistance to pressure and deformation of the grille body 11, making it particularly suitable for harsh environments such as in-ground lights that need to withstand external loads. In this embodiment, the light source 4 is an LED light source. The mounting cavity 31 is also equipped with a power driver, which is electrically connected to the light source 4. The function of the power driver is to convert the mains power into the current required by the LED light source. The power driver and related circuit connections are existing technologies, so they are not shown in the figure or described in the text.

[0031] To further explain, it also includes a face ring 7, which abuts against the periphery of the light-emitting plate 6, and the face ring 7 covers the opening of the embedded part 2.

[0032] The outer wall of the face ring 7 is provided with external threads, and the inner wall of the top of the lamp body 3 is provided with internal threads. Through the cooperation of the internal and external threads, the face ring 7 is fixed to the top of the lamp body 3, thereby covering the opening of the embedded part 2. Specifically, the function of the face ring 7 is to seal the opening when the top opening accuracy of the lamp body 3 is insufficient, thus filling the deficiency of the top opening accuracy of the lamp body 3 and the embedded part 2.

[0033] To further explain, the inner wall of the lamp body 3 is provided with an annular mounting step 32, and the mounting ring 121 of the frame 12 is fixed on the mounting step 32.

[0034] Specifically, the mounting ring 121 is fixed to the mounting step 32 with adhesive. Unlike the point-concentration pressure generated by screw fixing, the adhesive can form a uniform and continuous bonding layer on the entire annular contact surface between the mounting ring 121 and the mounting step 32, achieving a highly reliable connection with full circumferential continuity and no stress concentration. This also simplifies assembly, improves efficiency, and eliminates the tedious steps of machining threaded holes and aligning and tightening multiple screws on the lamp body 3 and the mounting ring 121.

[0035] To further explain, the lamp body 3 has an annular glue groove 33 inside, the glue groove 33 is filled with glue, and the light-emitting plate 6 is fixed above the glue groove 33 by the glue.

[0036] By setting up a dedicated glue tank 33, a preset and sufficient space is provided for the glue, which ensures the accuracy and consistency of the glue application amount. The glue cures in the glue tank 33, which can completely fill and seal the assembly gap between the light-emitting plate 6 and the lamp body 3, forming a continuous and dense annular sealing ring. This effectively reduces the possibility of moisture, dust and corrosive gases seeping into the core area of ​​the lamp body 3 from the top.

[0037] To further explain, the bottom of the lamp body 3 is provided with a first through hole 311 that communicates with its mounting cavity 31, and a fastener 3111 is provided in the first through hole 311.

[0038] During assembly, the light-emitting plate 6 and the lamp body 3 are sealed with glue in the glue tank 33. The first through hole 311 allows the interior of the lamp body 3 to communicate with the outside. After the light-emitting plate 6 is fixed with glue, the first through hole 311 is sealed with fastener 3111. This effectively prevents the gas inside the lamp body 3 from expanding and breaking through the not-yet-dried glue, thus damaging the sealing of the underground lamp. In this embodiment, the fastener 3111 can be a screw.

[0039] To further explain, the bottom of the lamp body 3 is provided with a second through hole that communicates with its mounting cavity 31, and a waterproof connector 3121 is provided in the second through hole.

[0040] The waterproof connector 331 is used to introduce an external power cord, enabling the in-ground light to be used in outdoor and humid environments.

[0041] To further explain, the outer wall of the lamp body 3 is provided with a plurality of convex ring structures 34, the convex ring structures 34 are arranged horizontally, and the plurality of convex ring structures 34 are arranged at intervals in the vertical direction.

[0042] Specifically, the aforementioned convex ring structures 34 can increase the outer surface of the lamp body 3, that is, increase the heat dissipation area of ​​the lamp body 3, avoid local heat accumulation, and at the same time, they can also serve as reinforcing ribs to improve the compressive strength of the lamp body 3 and enhance the stability of the structure.
