Description

Technical Field

[0001] This utility model belongs to the field of anti-glare lens technology, specifically a deep-cover anti-glare lens. Background Technology

[0002] In the development of modern lighting technology, effectively improving light utilization efficiency and optimizing visual experience has always been a core focus of the industry. Whether it's indoor commercial lighting, home lighting, or outdoor road lighting and landscape lighting, there are increasingly stringent requirements for directional light projection and glare control. To better adapt to the lighting needs of different scenarios and achieve precise light control and comfortable presentation, a deep-cover anti-glare lens has emerged.

[0003] Meanwhile, the patent specification with application number CN218409784U discloses an anti-glare lens and lens module. "The aforementioned anti-glare lens has a light-emitting surface formed on the side facing away from the light source. A pre-refracting portion is provided at the center of the light-emitting surface, and a deep hole is opened in the pre-refracting portion. An incident portion is provided inside the anti-glare lens, and an incident hole corresponding to the deep hole is formed in the incident portion. The incident portion has a bottom arc surface located between the incident hole and the deep hole. A first light-emitting refractive surface is formed on the side of the pre-refracting portion adjacent to the incident hole. A second light-emitting refractive surface is provided on the light-emitting surface, and the second light-emitting refractive surface is arranged around the opening of the pre-refracting portion. Through the built-in deep hole, a large light-blocking angle is formed between the first and second light-emitting refractive surfaces, allowing light passing through the second light-emitting refractive surface to be directly emitted from the opening of the pre-refracting portion, thereby reducing the diffusion of residual light and achieving the effect of preventing glare."

[0004] Existing anti-glare lens devices have poor anti-glare performance on the reflective surface during use, and the angle between the light output angle and the viewing angle is small, which easily causes glare problems. Secondly, the relative position of the lens and the deep cover is fixed, and the distance between the two cannot be adjusted according to the lighting requirements, which makes it difficult to adapt the light output range and light spot shape to different scenarios, and the adjustment structure is inconvenient to operate.

[0005] Therefore, a deep-coverage anti-glare lens is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a deep-mask anti-glare lens, which effectively increases the angle between the lens's light output angle and the viewing angle, significantly optimizing the anti-glare effect. At the same time, the PMMA lens body and the aluminum alloy deep-mask body work together to balance optical transmission efficiency and structural stability, and to achieve flexible adjustment of the distance between the lens and the deep-mask, thus adapting to the light output range and light spot shape requirements of different scenarios.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a deep-cover anti-glare lens, comprising a deep-cover body, a mounting base installed at the top of the deep-cover body for connecting and fixing to an external support structure, a lamp body installed at the bottom of the mounting base, a mounting groove for use with the lamp body at the top of the deep-cover body, the deep-cover body having a cup-shaped structure, a reflective surface provided on the inner sidewall of the deep-cover body, a regularly distributed texture on the inner surface of the reflective surface, and a lens mounting bracket fitted onto the outer surface of the deep-cover body, with the lens body fixedly mounted on the inner surface of the lens mounting bracket.

[0008] Preferably, the lens body is made of PMMA material, and the deep cover body is made of aluminum alloy material.

[0009] Preferably, the reflective surface of the deep cover body has a deepened design, and by combining the reflective surface with regularly distributed textured patterns, the angle between the light emission angle and the viewing angle of the lens body reaches more than 30 degrees.

[0010] Preferably, the lens mounting bracket includes two threaded holes formed on the lens mounting bracket, and locking bolts are threaded onto the inner surfaces of the two threaded holes. Two receiving grooves are formed on the outer surface of the deep cover body, and locking blocks are slidably connected to the inner surfaces of the two receiving grooves. The two locking blocks are rotatably connected to the two locking bolts respectively.

[0011] Preferably, the depth of the receiving groove is greater than the thickness of the locking block.

[0012] Preferably, the locking block has a silicone anti-slip pad at one end near the inner wall of the receiving groove.

[0013] Preferably, an adjusting handwheel is installed at one end of each of the two locking bolts.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model adopts a deep design for the reflective surface of the deep cover body, and is combined with the regular distribution of texture on the inner surface. Under the synergistic effect of the two, the angle between the light output angle of the lens and the viewing angle can be effectively increased, significantly optimizing the anti-glare effect. At the same time, the PMMA lens body and the aluminum alloy deep cover body are combined to take into account both optical transmission efficiency and structural stability.

[0016] 2. This utility model uses a lens mounting bracket and a deep cover body to form a sleeve structure, along with a threaded locking bolt and a sliding locking block. When the locking bolt is loosened, the lens mounting bracket can slide smoothly along the deep cover body. Under the operation of the adjustment handwheel, the distance between the lens and the deep cover can be flexibly adjusted, thereby adapting to the light output range and light spot shape requirements of different scenarios.

[0025] 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.

[0026] like Figures 1 to 5 As shown, this utility model provides a deep-cover anti-glare lens, including a deep-cover body 1, a mounting base 2 installed at the top of the deep-cover body 1 for connecting and fixing to an external support structure, a lamp body 21 installed at the bottom of the mounting base 2, and a mounting groove 12 for use with the lamp body 21 at the top of the deep-cover body 1. The deep-cover body 1 has a cup-shaped structure, and a reflective surface 13 is provided on the inner side wall of the deep-cover body 1. The inner surface of the reflective surface 13 has regularly distributed textures, and a lens mounting bracket 3 is sleeved on the outer surface of the deep-cover body 1. The lens body 31 is fixedly installed on the inner surface of the lens mounting bracket 3. By integrating the deep-cover body 1, the mounting base 2, the lamp body 21 and the lens mounting bracket 3, a complete anti-glare optical system is formed. The mounting base 2 realizes a stable connection between the overall structure and the outside, ensuring the accurate position of each component and providing basic structural support for the anti-glare function.

[0027] Specifically, the lens body 31 is made of PMMA material, and the deep cover body 1 is made of aluminum alloy material. The PMMA material ensures the high light transmittance of the lens, while the aluminum alloy material enhances the heat dissipation and structural strength of the deep cover body 1. The combination of the two takes into account both optical performance and structural stability, and extends the service life of the device.

[0028] like Figures 1 to 5 As shown, the reflective surface 13 of the deep cover body 1 has a deepened design. By combining the reflective surface 13 with the regularly distributed textured surface, the angle between the light output angle and the viewing angle of the lens body 31 reaches more than 30 degrees. The synergistic effect of the deepened reflective surface 13 and the textured surface effectively increases the angle between the light output angle and the viewing angle, reduces the stimulation of glare to the human eye, and improves the comfort of lighting.

[0029] Furthermore, the lens mounting bracket 3 includes two threaded holes 36 formed on the lens mounting bracket 3. The inner surfaces of the two threaded holes 36 are threaded with locking bolts 35. The outer surface of the deep cover body 1 has two receiving grooves 11. The inner surfaces of the two receiving grooves 11 are slidably connected with locking blocks 32. The two locking blocks 32 are rotatably connected to the two locking bolts 35 respectively. The cooperation of the threaded holes 36, locking bolts 35, receiving grooves 11 and locking blocks 32 realizes the sliding adjustment and stable locking of the lens mounting bracket 3, which makes it easy to flexibly change the lens position according to the needs and adapt to different lighting scenarios.

[0030] like Figures 1 to 5 As shown, the depth of the receiving groove 11 is greater than the thickness of the locking block 32, ensuring that the lens mounting bracket 3 slides smoothly without jamming or obstruction, thus improving the smoothness of the adjustment operation.

[0031] It is worth noting that the locking block 32 is provided with a silicone anti-slip pad 34 at one end near the inner wall of the receiving groove 11. The anti-slip pad 34 increases the friction, making it less likely for the lens mounting bracket 3 to loosen after locking, and preventing position displacement due to vibration.

[0032] like Figures 1 to 5 As shown, an adjusting handwheel 33 is installed at one end of each of the two locking bolts 35. The adjusting handwheel 33 is easy to operate manually, and locking and loosening can be completed without tools, simplifying the adjustment process and improving the ease of use of the device.

[0033] Working principle and process: After the lamp body 21 emits light, the light is reflected by the texture of the reflective surface 13 of the deep cover body 1 and emitted through the lens body 31. The deepened design of the reflective surface 13, combined with the texture, increases the angle between the light output angle and the viewing angle, thus achieving anti-glare. During adjustment, turn the adjusting handwheel 33 to loosen the locking bolt 35, slide the lens mounting bracket 3 to the appropriate position, and then tighten the locking bolt 35 by adjusting the handwheel 33, so that the locking block 32 is pressed against the receiving groove 11 by the anti-slip soft pad 34 to complete the locking, so as to adapt to different lighting needs.

[0034] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
