Description

Technical Field

[0001] This utility model relates to the field of optical diffusion film technology, and specifically to an optical diffusion film surface diffusion structure. Background Technology

[0002] Optical diffusion film is an optical material with light diffusion function, mainly used to improve the distribution and uniformity of light, thereby enhancing the visual effect and energy efficiency of products. It is typically made from polyethylene terephthalate (PET) as the substrate through a special processing technology, resulting in excellent mechanical and optical properties. The surface diffusion structure of optical diffusion film is the core technology for achieving uniform light diffusion through specific microstructure design.

[0003] This invention discloses an optical diffusion film surface diffusion structure (publication number CN211979248U). The technical problem this invention aims to solve is to provide an optical diffusion film surface diffusion structure that replicates the structure on a diffusion film, achieving the same effect of uniform light distribution, effectively increasing luminous efficiency, reducing the proportion of added diffusion particles, lowering costs, and being environmentally friendly and energy-saving. The optical diffusion film surface diffusion structure comprises multiple diffusion grooves arranged on the surface of the diffusion film body. The shapes of the diffusion grooves are hemispherical, semi-ellipsoidal, or short cylindrical. This invention, by arranging hemispherical, semi-ellipsoidal, or short cylindrical diffusion grooves on the surface of the diffusion film, achieves the same effect of uniform light distribution, effectively increasing luminous efficiency, reducing the proportion of added diffusion particles, lowering costs, and being environmentally friendly and energy-saving.

[0004] The existing technology has the following shortcomings: the surface diffusion structure of the existing optical diffusion film is unevenly distributed, which makes it easy for the optical diffusion film to diffuse light unevenly when it diffuses light. This makes it impossible for the optical diffusion film to diffuse light evenly in different directions stably. At the same time, the surface of the optical diffusion film is prone to scratches, which will affect the working effect of the optical diffusion film. Utility Model Content

[0005] The purpose of this invention is to provide a surface diffusion structure for an optical diffusion film. By combining optical protrusions and diffusion grooves, the diffusion mechanism can scatter light more fully. The equally spaced optical protrusions and diffusion grooves can diffuse light more uniformly, avoiding uneven light diffusion in the optical diffusion film. This effectively increases the optical diffusion effect of the optical diffusion film and solves the above-mentioned shortcomings in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an optical diffusion film surface diffusion structure, comprising a diffusion film body, and further comprising:

[0007] The diffusion mechanism, located inside the main body of the diffusion membrane, is used to scatter the core light.

[0008] The diffusion mechanism includes a diffusion layer, with multiple optical protrusions adhered to the top of the diffusion layer, and multiple diffusion grooves formed on the top surface of the diffusion layer, the diffusion grooves being disposed in the gaps between four adjacent optical protrusions.

[0009] Preferably, the diffusion film body includes a substrate and a protective layer, and an adhesive layer is disposed on the top of the substrate, wherein the top of the adhesive layer is adhered to the bottom of the diffusion layer.

[0010] Preferably, the protective layer is adhered to the top of the diffusion layer and is disposed on the outside of the optical protrusion.

[0011] Preferably, the front vertical cross-section of the optical protrusions and the diffusion grooves are all set as semi-circular structures, and the plurality of optical protrusions and diffusion grooves are arranged at equal intervals.

[0012] Preferably, the diameter of the optical protrusion is the same as the diameter of the diffusion groove, and the optical protrusion is made of resin material.

[0013] Preferably, the protective layer is made of acrylic resin and the diffusion layer is made of polyethylene terephthalate.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] Multiple optical protrusions arranged at equal intervals effectively diffuse light. Diffusion grooves between four adjacent protrusions further enhance light diffusion. Both the optical protrusions and diffusion grooves are hemispherical to prevent uneven light diffusion, effectively increasing the light diffusion effect of the optical diffusion film and improving its performance. An adhesive layer strengthens the connection between the diffusion mechanism and the main body of the diffusion film, ensuring stable optical diffusion. A protective layer protects the diffusion mechanism from external damage and scratches, guaranteeing its light diffusion effect and extending its lifespan. This ensures stable light diffusion.

[0024] This utility model provides, for example Figure 1 The optical diffusion film surface diffusion structure shown includes a diffusion film body 1, and further includes:

[0025] The diffusion mechanism 2, located inside the diffusion film body 1, is used to scatter the core light. The diffusion mechanism 2 enables the optical diffusion film to effectively diffuse the light.

[0026] In order to diffuse the light evenly, such as Figures 1-4 As shown, the diffusion mechanism 2 includes a diffusion layer 201. Multiple optical protrusions 202 are adhered to the top of the diffusion layer 201, and multiple diffusion grooves 203 are formed on the top surface of the diffusion layer 201. The diffusion grooves 203 are disposed in the gaps between four adjacent optical protrusions 202. The multiple optical protrusions 202 can diffuse the optical fiber, and the diffusion grooves 203 formed in the gaps between four adjacent optical protrusions 202 can further diffuse the light. The multiple optical protrusions 202 and diffusion grooves 203 arranged at equal intervals make the light diffusion more uniform, which can effectively improve the light diffusion effect of the optical diffusion film, and thus enable the optical diffusion film to diffuse the light more fully and uniformly. The arrangement of the hemispherical optical protrusions 202 and diffusion grooves 203 enables the optical diffusion film to diffuse the light stably, so that the optical diffusion film has a good optical diffusion effect.

[0027] In order to ensure a tight connection between the diffusion mechanism 2 and the diffusion membrane body 1, such as Figures 1-3As shown, the diffusion film body 1 includes a substrate 101 and a protective layer 103. An adhesive layer 102 is disposed on the top of the substrate 101, and the top of the adhesive layer 102 is adhered to the bottom of the diffusion layer 201. The protective layer 103 is adhered to the top of the diffusion layer 201 and is disposed on the outer side of the optical protrusion 202. The protective layer 103 is made of acrylic resin, and the diffusion layer 201 is made of polyethylene terephthalate. The adhesive layer 102 ensures a tight connection between the diffusion mechanism 2 and the substrate 101, making the connection between the diffusion mechanism 2 and the diffusion film body 101 more secure. The connection between the diffusion mechanism 2 and the diffusion film body 101 is strengthened to prevent loosening during use, thus ensuring that the diffusion mechanism 2 can stably diffuse light. At the same time, the protective layer 103 protects the surface of the diffusion mechanism 2, preventing damage to the surface of the diffusion mechanism 2 from external exposure. This also prevents the surface of the optical diffusion film from being scratched by external forces, thus ensuring the light diffusion effect of the diffusion mechanism 2 and enabling the optical diffusion film to stably diffuse the optical fiber, thereby extending the service life of the optical diffusion film.

[0028] To make the light diffusion more uniform, such as Figures 2-4 As shown, the front vertical section of the optical protrusions 202 and the diffusion grooves 203 are both set as semi-circular structures. Multiple optical protrusions 202 and diffusion grooves 203 are arranged at equal intervals. The diameter of the optical protrusions 202 is the same as the diameter of the diffusion grooves 203. The optical protrusions 202 are made of resin material. The equally spaced optical protrusions 202 can fully diffuse the light. At the same time, the diffusion grooves 203 opened in the gaps between four adjacent optical protrusions 202 can further diffuse the light, making the light diffusion more uniform. The hemispherical optical protrusions 202 and diffusion grooves 203 can diffuse the light more uniformly, so that the diffusion mechanism 2 can diffuse the light uniformly, which can avoid the uneven dispersion of light during the diffusion process, and thus effectively increase the light diffusion effect of the optical diffusion film.

[0029] In the production of the optical diffusion film, an adhesive layer 102 is coated on the surface of the substrate 101. Then, UV-curable resin is transferred onto the surface of the diffusion layer 201 made of polyethylene terephthalate, forming hemispherical optical protrusions 202 arranged at equal intervals on the surface of the diffusion layer 201. Diffusion grooves 203 are then formed in the gaps between four adjacent optical protrusions 202 on the surface of the diffusion layer 201, with the same diameter as the optical protrusions 202. Next, a protective layer 103 made of acrylic resin is coated onto the top surface of the diffusion mechanism 2. Finally, the composite diffusion mechanism 2 is bonded to the top of the adhesive layer 102, thus completing the optical diffusion film composite. This allows the film to diffuse light. During diffusion, the light can be uniformly diffused by the hemispherical optical protrusions 202 arranged at equal intervals. The light can be further diffused by the multiple diffusion grooves 203 opened in the gaps between four adjacent optical protrusions 202, so that the light diffusion is more uniform and sufficient, which can effectively increase the light diffusion effect of the optical diffusion film. At the same time, the protective layer 103 on the surface of the diffusion mechanism 2 can protect the diffusion mechanism 2 and prevent damage and scratches. It can ensure the light diffusion effect of the diffusion mechanism 2 and extend the service life of the optical diffusion film. This embodiment specifically solves the problem of uneven light diffusion of optical diffusion films in the prior art.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
