Description

Technical Field

[0001] This utility model belongs to the field of lighting fixture technology, and in particular relates to an anti-glare lens structure and arrangement structure. Background Technology

[0002] With increasing emphasis on glare reduction, most high-quality anti-glare lighting fixtures are equipped with anti-glare covers. However, most anti-glare covers are assembled in a non-removable manner, making it difficult to quickly replace them and adapt to different anti-glare requirements. Furthermore, many lighting fixtures suffer from poorly designed optical lenses, causing light to be partially blocked by the anti-glare cover, resulting in layering effects. Sometimes, the lenses themselves are flawed, leading to numerous layered light spots during illumination, severely impacting aesthetics, causing glare, and affecting the user experience. Utility Model Content

[0003] This invention provides an anti-glare lens structure and arrangement to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] An anti-glare lens structure and arrangement includes an anti-glare cover and a lens. The lens is designed with snap-fit ​​features, while the anti-glare cover has snap-fit ​​features; the two are installed together by snap-fit ​​assembly. The lens has a countersunk hole, within which a convex lens with an off-axis design is formed, meaning the incident surface of the convex lens is located within the countersunk hole, and the inner wall surface of the countersunk hole is designed as a refractive surface. The exit surface of the lens is designed with a Fermat spiral bead texture. The inner surface of the lens is designed as a polarizing total internal reflection surface. The lens has four or more countersunk holes, each with an aligned LED light source and a formed convex lens.

[0006] Preferably, the lens is formed with a surrounding edge, and the fastener is formed on the surrounding edge, with at least two fasteners.

[0007] Preferably, the LED light source uses 3030-2835SMD LED beads.

[0008] Preferably, the anti-glare shield is formed with a protective frame.

[0009] Preferably, the anti-glare cover is based on a hexagonal layout and is designed with seven identical cover bodies to accommodate seven lenses for fastening and assembly.

[0010] Preferably, each of the covers is formed with a buckle to fasten the lens for secure installation.

[0011] Preferably, each of the covers is formed based on the reverse curvature design of a circumscribed hexagon, and the inner surface in the light-emitting direction is treated with a diffuse reflection process.

[0012] Compared with existing technologies, the advantages of this utility model are:

[0013] 1. The light-emitting surface of the lens adopts a Fermat spiral array, and each small bead is an independent focusing convex lens. This structural texture design can not only improve the concentration of energy of the main lobe of the focal point to improve optical resolution and accuracy, but also reduce light waste and further enhance the anti-glare effect, making the light more evenly distributed.

[0014] 2. Up to four countersunk holes can be made in the lens, and each countersunk hole is designed with a convex lens with a polarizing convex lens structure. The four convex lenses can form a total internal reflection lens module. Each convex lens is equipped with an LED light source for operation. This design allows the four convex lenses to independently control the direction of their optical angles. Because of the law of independent propagation of light, the light emitted by each lens propagates independently without interference. Each convex lens needs to polarize the light towards the center during operation to reduce the light hitting the housing, thereby avoiding phenomena such as uneven light spots and aperture caused by triple reflection, reducing the efficiency loss of medium reflection. In addition, the four lenses can also be equipped with two different color temperature LED light sources. Subsequently, by grouping and controlling the circuit and loop, the switching of the three color temperatures can be realized. This design can also ensure that the light spot is uniform and does not layer.

[0015] 3. Each lens has four convex lenses, which is a set of total internal reflection lens modules and also a light outlet of an anti-glare shield. It can achieve polarization in four directions, so that the light spot is cross-shaped. The anti-glare shield of this utility model is arranged in a hexagonal array. After multiple shields emit light, light overlap can be achieved. The overlap of multiple light sources can achieve the mixed distribution of light in each direction, so that the light spot can be circular. While improving its use and visual effect, it can also increase the anti-glare effect, making the UGR of this utility model less than 19.

[0016] 4. The lens and anti-glare shield of this utility model have a simple and reasonable structure, which facilitates assembly and combination during production, as well as daily maintenance and disassembly. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 8 As shown, this utility model is an anti-glare lens structure and arrangement structure, mainly composed of an anti-glare cover (1) and a lens (2). The lens (2) is designed with a snap fastener (20), while the anti-glare cover (1) is formed with a buckle (10). The two are installed together by snap fastening.

[0026] It should be noted that the lens (2) has a countersunk hole (22) and a convex lens with a polarizing convex lens structure is formed in the countersunk hole (22). The basic design of the lens (2) has four countersunk holes (22), that is, the incident surface (21) of the convex lens is located in the countersunk hole (22), and the inner wall surface (23) of the countersunk hole (22) is designed as a refractive surface. The four convex lenses can form a total internal reflection lens module. Each convex lens is equipped with an LED light source (3) for operation. The LED light source (3) uses 3030-2835SMD LED beads. This design allows the four convex lenses to independently control the direction of the optical angle. According to the law of independent propagation of light, the light emitted by each lens propagates independently and will not interfere. Each convex lens needs to polarize the light towards the center during operation to reduce the light hitting the cover (12) to avoid the phenomenon of uneven light spot caused by the third reflection, and reduce the efficiency loss of medium reflection.

[0027] Regarding lens (2), there is also:

[0028] 1. The exit surface (25) of the lens (2) is designed with a Fermat spiral bead texture. This design enables each bead to be an independent focusing convex lens. This structural texture design not only enables super-diffraction-limited focusing of the incident light field and effectively reduces the influence of the side lobes on the focal energy, thereby improving the concentration of the focal main lobe energy, but also improves the optical resolution and accuracy. It also ensures that the light travels along the optimal path, reduces light waste, concentrates the illumination of key areas, and further enhances the anti-glare effect, making the light more evenly distributed and reducing glare.

[0029] 2. The inner surface (26) of the lens (2) is designed as a polarizing total reflection surface, which can be used in conjunction with a convex lens of a total internal reflection lens module to control the refraction of light and reduce glare and dazzling light.

[0030] 3. It is formed with a rim (24), and the fasteners (20) are opened on the rim (24). There are at least two fasteners (20) to align with the buckles (10) on each cover (12) of the anti-glare cover (1), thereby achieving fastening assembly.

[0031] The anti-glare cover (1) is formed with a protective frame (11), an internal threaded guide post and a buckle. The forming of the protective frame (11) can increase the overall strength of the anti-glare cover (1) and can protect the inner cover (12) to a certain extent. The internal threaded guide post and the buckle can play a role in auxiliary assembly and positioning for subsequent assembly.

[0032] Regarding the anti-glare shield (1), it can be noted that the anti-glare shield (1) is based on a hexagonal layout and is designed to have seven identical shield bodies (12) for the seven lenses (2) to be snapped together. It can be further explained that the number of shield bodies (12) corresponds to the number of lenses (2). Each shield body (12) is based on the inverse arc design of a circular circumscribed hexagon, and the inner surface (13) in the light-emitting direction is treated with a diffuse reflection process. The inverse arc structure design can prevent the light spot from being concentrated and reflected to a certain point, thus affecting the uniformity of the light spot. The circular opening with an inverse arc design can make the light spot reflect even in the hexagonal light-emitting opening. In addition, the overall hexagonal structure arrangement saves more space, and the light spot can also meet the requirement that it must be circular.

[0033] The assembly of this utility model adopts a snap-fit ​​method, which can greatly save the mold cost and product inventory cost of anti-glare cover (1) of different sizes and different lenses (2). Since each lens is the same optical, but the anti-glare cover has many sizes, this design is convenient for assembly and combination during production, and also convenient for daily disassembly and replacement.

[0034] The anti-glare shield (1) of this utility model is arranged in a hexagonal array. After multiple shields (12) emit light, light overlap can be achieved. The overlap of multiple light sources can achieve the mixed distribution of light in each direction, so that the light spot can be circular. While improving its use and visual effect, it can also increase the anti-glare effect, making the UGR of this utility model less than 19, which meets the anti-glare requirements, and the structure is reasonable and simple.
