Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of diffusion plates, in particular to a micro-prism anti-glare diffusion plate. Background Art
[0002] Anti-glare diffuser is a technology used to adjust the surface characteristics of optical devices to reduce or prevent light glare and achieve a more uniform light scattering effect. Common anti-glare diffusers use prism structures, which can effectively change the direction and scattering angle of incident light, so that the light can be evenly scattered and glare can be reduced. However, due to the prism structure, the surface of the diffuser is uneven, and dust and the like are easily trapped inside the concave surface. It is difficult to wipe off the dust when wiping, resulting in a decrease in light transmittance and poor light scattering effect. Utility Model Content

[0005] The connection mechanism includes a fixing column fixedly connected to the diffusion substrate, springs are arranged inside both ends of the fixing column, and a locking column is movably connected to the spring, one end of the locking column is inserted into a locking block, and the locking block is fixedly connected to the side wall of the mask plate.
[0006] Preferably, a plurality of rows of equally spaced refraction grooves are provided at the bottom of the diffusion substrate, and the inner walls of the refraction grooves are arc surfaces.
[0007] Preferably, a plurality of microstructure grooves are provided on the surface of the diffusion substrate, the microstructure grooves are arranged continuously with each other, the upper part of the microstructure groove is hexagonal and the lower part is a conical bottom.
[0008] Preferably, a protrusion is fixedly provided on the outer wall of the locking block, and the protrusion is slidably arranged in a through hole provided on the fixing column.
[0009] Preferably, the fixing frame is provided with two mounting holes at positions close to the two side walls.
[0010] Preferably, two grooves for accommodating the connecting mechanism are provided on the inner wall of the fixing frame.
[0011] By means of the above technical solution, the utility model provides a micro-prismatic anti-glare diffuser plate, which has at least the following beneficial effects:
[0012] 1. The micro-prismatic anti-glare diffuser plate is provided with a connecting mechanism and a mask plate, and the mask plate is fixed on the diffuser substrate by the connecting mechanism. Since the surface of the mask plate is smooth, dust on the mask plate can be directly wiped off, which can avoid the problem that dust adheres to the diffuser substrate and is difficult to clean, thereby ensuring its light transmittance and light scattering efficiency. The setting of the connecting mechanism can facilitate the disassembly and assembly of the mask plate, and the mask plate can be replaced separately when it is damaged.
[0013] 2. The micro-prismatic anti-glare diffuser plate is provided with a refraction groove and a micro-structure groove. The light first enters the refraction groove.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Micro-prismatic anti-glare diffuser uses microstructured surface technology to add micron-level concave-convex structures on the crystal facets, thereby achieving more uniform light reflection and diffusion effects. Compared with traditional prismatic anti-glare diffuser, the micro-prismatic structure can achieve more uniform light reflection and diffusion effects, and improve the consistency of visual effects. With superior optical performance and reliability, it has gradually become one of the hot technology applications in the field of optical display.
[0025] Based on the technical defects of the existing technology that it is difficult to clean the dust on the diffusion plate, resulting in a decrease in light transmittance, please refer to Figure 1-Figure 6 The utility model provides a micro-prismatic anti-glare diffusion plate, which uses a connecting mechanism 3 to fix a mask plate 2 on a diffusion substrate 1. Since the surface of the mask plate 2 is smooth, dust on the mask plate 2 can be directly wiped off, which can avoid the problem that dust adheres to the diffusion substrate 1 and is difficult to clean, thereby ensuring its light transmittance and light scattering efficiency. The utility model comprises a diffusion substrate 1, and a mask plate 2 and a fixing frame 4 are provided on the diffusion substrate 1. Connecting mechanisms 3 are provided on both sides of the mask plate 2. The connecting mechanism 3 is fixed to the diffusion substrate 1, and the fixing frame 4 is attached to the outer side of the mask plate 2. The mask plate 2 is first fixed to the diffusion substrate 1 by using the connecting mechanism 3, and then the diffusion substrate 1 and the mask plate 2 are fixed to the lamp together by the fixing frame 4.
[0026] To facilitate the disassembly and assembly of the mask plate 2, please refer to Figure 4 The connecting mechanism 3 includes a fixing column 31 fixedly connected to the diffusion substrate 1, springs 32 are provided inside both ends of the fixing column 31, and a locking column 33 is movably connected through the spring 32, one end of the locking column 33 is inserted into a locking block 34, and the locking block 34 is fixedly connected to the side wall of the mask plate 2; when the mask plate 2 is installed, the locking column 33 is inserted into the locking block 34 by the elastic force of the spring 32, so that the connection and fixation of the mask plate 2 can be achieved.
[0027] In order to make the light refract and diffuse initially, a plurality of rows of equally spaced refraction grooves 11 are provided at the bottom of the diffusion substrate 1 , and the inner wall of the refraction groove 11 is an arc surface; when the light enters the refraction groove 11 , it can be diffusely reflected along the inner wall of the refraction groove 11 .
[0028] In order to achieve a more uniform light reflection and diffusion effect, a plurality of microstructure grooves 12 are provided on the surface of the diffusion substrate 1. The microstructure grooves 12 are arranged continuously with each other, and the upper part of the microstructure grooves 12 is hexagonal and the lower part is a conical bottom. After the light is initially refracted, it enters the microstructure grooves 12. The microstructure grooves 12 can effectively change the direction and scattering angle of the incident light, so that the light can be evenly scattered and glare can be reduced.
[0029] To facilitate the disassembly and assembly of the mask plate 2, a protrusion 35 is fixed on the outer wall of the locking block 34, and the protrusion 35 is slidably set in a through hole 36 opened on the fixing column 31; when disassembling, the locking column 33 is pulled to move by the protrusion 35, and after the locking column 33 is separated from the locking block 34, the mask plate 2 can be removed.
[0030] To facilitate the fixing of the whole, two mounting holes 41 are provided at positions of the fixing frame 4 close to the two side walls; the fixing frame 4 can be installed and fixed through the mounting holes 41, thereby forming the installation and fixation of the whole.
[0031] In order to facilitate the operation of the connecting mechanism 3 , two grooves 42 for accommodating the connecting mechanism 3 are provided on the inner wall of the fixing frame 4 ; the arrangement of the grooves 42 can expose the connecting mechanism 3 for easy operation.
[0032] Through the above embodiments, it can be known that: first, the mask plate 2 is covered on the diffusion substrate 1, and then the protrusion 35 is pulled to move the lock column 33 into the fixing column 31. After the mask plate 2 is installed, the protrusion 35 is released, and the lock column 33 is inserted into the lock block 34 under the elastic force of the spring 32, so that the mask plate 2 can be fixed, and then the fixing frame 4 is installed to the outside of the mask plate 2. When in use, the light first enters the refraction groove 11. Since the inner wall of the refraction groove 11 is a curved surface, it is first refracted and then enters the microstructure groove 12. After double refraction, the light has a better diffusion effect. And since the surface of the mask plate 2 is smooth, dust on the mask plate 2 can be directly wiped off.
