Description

Technical Field

[0001] The utility model relates to the technical field of lenses, in particular to a point cloud diffusion technology lens. Background Art

[0002] Glare is a common phenomenon in visual experience. It usually refers to the situation when the light is too strong or the light source is improperly positioned, causing visual discomfort or reduced visual quality.

[0003] The effects of glare on people include visual fatigue, blurred vision, headaches, and decreased concentration. If you are in this kind of environment for a long time, the harm will increase dramatically.

[0004] At present, in some environments with high light intensity and frequent flicker, since the outer protective lenses of some lighting equipment are ordinary plane mirrors or lens structures, the light is relatively concentrated after the lighting equipment emits the optical fiber. In this way, when the light hits the eyes, glare is very likely to occur. Therefore, it is necessary to design a lens that can diffuse the light to solve the glare problem caused by the lighting equipment.

[0005] The more common one is the point cloud diffusion technology. The lens is an advanced optical element, which is mainly used to improve the beam diffusion characteristics in the optical system.

[0006] This technology forms tiny dot structures on the surface or inside of the lens so that the light passing through the lens can be diffused according to the design requirements.

[0007] However, most point cloud diffusion technology lenses are single-layer diffusion structures. It is difficult to achieve optimal light diffusion in environments with high light concentration and high light intensity. Therefore, it is necessary to further improve them and increase their light structure to reduce the harm caused by glare. Utility Model Content

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Reference Figure 1-Figure 4 A point cloud diffusion technology lens, comprising a lens body 10, the lens body 10 comprises a base layer 11, a first anti-glare layer 12, a first diffusion layer 13, a filling layer 14, a first protective layer 15, a second anti-glare layer 16, a second diffusion layer 17, a second protective layer 18, and an anti-fog layer 19, the edge of the base layer 11 is bonded with the first anti-glare layer 12 by transparent resin glue, the two sides of the filling layer 14 are respectively bonded and fixed to the base layer 11 and the first anti-glare layer 12 by transparent resin glue, a plurality of first diffusion layers 13 are provided, and the first diffusion layers 13 are embedded On the first anti-glare layer 12 and the two are an integrally formed structure, the other side of the first anti-glare layer 12 and the other side of the first diffusion layer 13 are bonded with a first protective layer 15 by transparent resin glue, the other side of the base layer 11 is bonded with a second anti-glare layer 16 by transparent resin glue, a plurality of second diffusion layers 17 are provided and evenly distributed on the second anti-glare layer 16, the other side of the second diffusion layer 17 is bonded with a second protective layer 18 by transparent resin glue, and the other side of the first protective layer 15 and the other side of the second protective layer 18 are coated with an anti-fog layer 19.

[0028] It should be further explained that the base layer 11, the first anti-glare layer 12 and the first diffusion layer 13 are all made of synthetic resin materials. Synthetic resin lenses are much lighter than glass lenses and more comfortable to wear. They are especially suitable for users who wear glasses for a long time. Resin lenses have high impact resistance and are not easy to break, which greatly reduces the risk of injury due to lens breakage. They are especially suitable for children and people engaged in sports. Resin lenses are easier to cut, polish and otherwise process, and can produce more complex shapes and designs to meet different needs. Compared with glass lenses, resin lenses have lower production costs while still providing excellent optical performance.

[0029] It should be further explained that the first diffusion layer 13 is a quadrangular prism structure, and a plurality of first diffusion layers 13 are evenly diffused and distributed along the center point of the first anti-glare layer 12. By making a series of prism structures on the surface of the lens, the refraction and reflection characteristics of the prisms are used to achieve light diffusion. The prism structures can be regularly arranged or randomly arranged.

[0030] It should be further explained that the filling layer 14 is made of polycarbonate material. Polycarbonate has excellent impact resistance and toughness, and can maintain good impact performance even in low temperature environments. Polycarbonate has similar transparency and glossiness to glass, but is lighter and less prone to breakage. Polycarbonate has a lower coefficient of thermal expansion and good dimensional stability, and can maintain precise size and shape during processing and use.

[0031] It should be further explained that the first protective layer 15 and the second protective layer 18 are both made of polyvinyl chloride film material. The transparent PVC film has good transparency and can provide a clear line of sight. It is suitable for occasions requiring visual transparency, such as packaging, medical supplies, and building windows. The PVC material has excellent weather resistance and can resist the influence of ultraviolet rays, temperature changes, and humidity. It is suitable for outdoor use. The transparent PVC film has good wear resistance and chemical resistance, and can resist the erosion of a variety of chemicals and extend its service life. The PVC material has good waterproof and moisture-proof properties and is suitable for applications in humid environments, such as bathroom partitions, raincoats, and waterproof packaging.

[0032] It should be further explained that the second anti-glare layer 16 is made of nano-scale silica material. Silica exhibits excellent stability in most chemical environments and is not easily corroded by acids or alkalis. In the visible light range, the silica film is transparent, which makes it have important applications in optical devices and display technology. Silica has a low thermal expansion coefficient and is suitable for applications that require thermal stability.

[0033] It should be further explained that the second diffusion layer 17 is a hemispherical groove structure, and a plurality of second diffusion layers 17 are diffusely distributed along the center of the second anti-glare layer 16 to form randomly arranged microstructures (such as protrusions or depressions), which diffuse light by scattering.

[0034] It should be further explained that the anti-fog layer 19 is made of polyvinyl alcohol coating material, which has good film-forming and adhesion properties. In the application of anti-fog coating, PVA is often used as a base material, and the anti-fog effect is achieved by adding other functional ingredients. The main purpose of the anti-fog coating is to prevent surface condensation, thereby maintaining transparency and clarity.

[0035] Working method: The first anti-glare layer 12 and the second anti-glare layer 16 arranged on the lens body can achieve a double diffusion effect on the optical fiber, which can avoid glare to the greatest extent when the light intensity is high and the light is concentrated. The quadrangular prism structure arranged on the first diffusion layer 13 can diffuse and reflect the light. The dense distribution of the second diffusion layer 17 can further diffuse the light emitted through the first diffusion layer 13 to the greatest extent.

[0036] The first anti-glare layer 12 can be protected from scratches by the first protective layer 15, and the second anti-glare layer 16 can be protected from scratches by the second protective layer 18. In combination with the anti-fog layer 19 outside the first protective layer 15 and the second protective layer 18, external fog can be prevented from gathering on the lens body and affecting the normal passage of light.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
