[0002] PC board material is also called board material, Kapron board material, is a kind of excellent comprehensive performance, with outstanding physical, mechanical, electrical and thermal performance, and is called "transparent plastic king".

[0003] Through the retrieval, patent application No. CN202320037489.4 discloses a kind of anti -dazzle type PC board material, although the device is when using by being coated with anti -dazzle modifier on the outside of dazzle PC board body, to realize certain anti -dazzle effect, but the device when using, its anti -dazzle means is relatively single, only rely on surface coating, it is difficult to carry out multi-angle, deep regulation and control to light. And neither can effectively enhance light scattering, nor can optimize structural strength and heat insulation performance. UTILITY MODEL CONTENT

[0004] In view of the deficiencies of the prior art, the utility model provides a PC sunlight board with anti -dazzle function, solves the problems raised in the background art.

[0005] The technical problem solved by the utility model is as follows:

[0006] A kind of PC sunlight board with anti -dazzle function, including shell;

[0007] The inside of the shell is provided with substrate, the substrate is provided with hollow honeycomb layer, the hollow honeycomb layer is provided with gradient refractive index composite layer, the gradient refractive index composite layer is provided with PC board;

[0008] The PC board is provided with microprism array, and the microprism array is evenly distributed on PC board, the height of microprism array is 0.2mm, and the pitch is 0.5mm.

[0009] On the basis of the above technical scheme, the utility model can also be improved as follows.

[0010] Further, the honeycomb axis of the hollow honeycomb layer is inclined at an angle of 15° to the substrate, and the inner wall of the honeycomb is coated with a 1 μm thick titanium dioxide scattering layer.

[0011] The beneficial effects of the above further scheme are:

[0012] Compared with the vertical arrangement, the 15° inclination angle of the honeycomb axis design changes the propagation path of the light in the hollow honeycomb layer, so that the light in the honeycomb structure experiences more reflections and refractions, further disrupting the propagation direction of the light and enhancing the scattering effect of the light. The 1 μm thick titanium dioxide scattering layer coated on the inner wall of the honeycomb utilizes the good light scattering performance of titanium dioxide. When light shines on this layer, it will be scattered in all directions, homogenizing the concentrated light and greatly reducing the intensity of the light, thereby effectively reducing the generation of glare. At the same time, the tilted honeycomb structure and the titanium dioxide scattering layer work together to increase the structural strength of the panel to some extent, and the hollow structure itself also helps to insulate and reduce heat transfer, improving the thermal comfort of the indoor environment.

[0013] Further, the outer layer of the gradient refractive index composite layer is a PC substrate plate containing 2wt% benzotriazole UV absorber, the middle layer is a PC substrate plate containing gradient-doped silica nanoparticles with a content increasing from 5wt% to 12wt%, and the inner layer is an antistatic modified PC substrate plate.

[0014] The beneficial effects of adopting the above further scheme are:

[0015] The PC substrate plate containing 2wt% benzotriazole UV absorber in the outer layer can effectively absorb ultraviolet rays. The benzotriazole UV absorber molecules can interact with ultraviolet photons, converting the ultraviolet energy into other forms such as heat energy, thereby blocking the ultraviolet rays from entering the interior of the solar panel and preventing the internal structure and other functional layers from being damaged by ultraviolet rays, prolonging the service life of the solar panel. The PC substrate plate containing gradient-doped silica nanoparticles in the middle layer has a refractive index that changes in a gradient manner due to the increasing content of nanoparticles from 5wt% to 12wt%. When light propagates in this medium, it will constantly change its propagation direction, gradually bending along the direction of refractive index change, further scattering and regulating the light, making the light more evenly distributed within the panel and reducing the probability of glare, while optimizing the light transmission efficiency. The antistatic modified PC substrate plate in the inner layer forms a conductive structure on the surface through special processes or the addition of antistatic agents, which can quickly dissipate accumulated static electricity, avoid the accumulation of dust and other impurities due to static electricity, maintain the cleanliness of the panel surface, and maintain the good optical performance of the solar panel.

[0016] Further, the micro-prism array is an isosceles triangle with a top angle α = 45° ± 2°.

[0017] The beneficial effects of adopting the above further scheme are:

[0018] The micro-prism array with an isosceles triangle and a top angle of 45°±2° can accurately refract and reflect light rays. When the light rays strike the micro-prism, according to the law of refraction and reflection of light, the micro-prism with the specific top angle can reflect or refract the direct light rays that may cause glare to other directions at a suitable angle, so that the light rays are more evenly dispersed. Compared with other top angle angles, this angle range can more effectively change the light propagation path, reduce the strong light directly entering the human eye, greatly enhance the anti-glare effect, provide a more comfortable visual experience for the user, and at the same time ensure that there is enough light transmission to maintain good lighting performance.

[0019] Further, the bottom of the substrate is provided with support ribs, and the support ribs are distributed in a grid shape.

[0020] The beneficial effects of the above further scheme are:

[0021] The support ribs distributed in a grid shape at the bottom of the substrate significantly enhance the structural strength and stability of the substrate. The grid-shaped design can provide support to the substrate in multiple directions, so that the solar panel is not prone to deformation, cracking and other damage when subjected to external forces such as wind force, snow pressure or acting force during installation. This stable structure not only prolongs the service life of the solar panel, but also ensures that it can normally play the functions of anti-glare, lighting and the like under various environmental conditions, and provides a reliable support basis for the entire solar panel system.

[0022] Further, the PC plate and the micro-prism array are bonded through an optical transparent adhesive layer, and the refractive index of the optical transparent adhesive layer is 1.50±0.05.

[0023] The beneficial effects of the above further scheme are:

[0024] The optical transparent adhesive layer plays a good bridging role. The refractive index thereof is 1.50±0.05, which matches the refractive indexes of the PC plate and the micro-prism array. When the light rays propagate from the PC plate to the micro-prism array, due to the matching of the refractive index of the optical transparent adhesive layer with the materials on both sides, at different medium interfaces, the light rays are less reflected and scattered due to the small difference in refractive index, so that the light rays can smoothly pass through, and the efficiency of light propagation is maintained. This enables the micro-prism array to fully play the role of refraction and reflection of light rays, and thus better realize the anti-glare function, while ensuring that the overall light transmission performance of the solar panel is not affected, so as to provide sufficient and soft light for the indoor.

[0025] The utility model provides a PC solar panel with anti -glare function. Possess following

[0026] Beneficial effects:

[0027] The base plate is arranged inside the shell, and a grid-shaped supporting rib design at the bottom of the base plate enhances the overall structural strength of the sunlight plate, so that the sunlight plate is more stable during use and is not easy to deform and damage, and can withstand certain external force and pressure.

[0028] The honeycomb axis of the hollow honeycomb layer is inclined at an angle of 15° to the base plate, and the inclined angle optimizes the structural performance of the plate, and the inner wall of the honeycomb is coated with a 1μm-thick titanium dioxide scattering layer, which can scatter light and reduce direct light, thereby achieving an anti-glare effect, and the hollow structure itself can also insulate and soundproof to some extent, thereby improving the use performance of the sunlight plate.

[0029] The outer layer of the gradient refractive index composite layer contains a PC base plate with 2wt% of a benzotriazole UV absorber, which can effectively absorb ultraviolet rays, protect the plate and the internal structure, and prolong the service life of the sunlight plate; the middle layer is a PC base plate with gradient-doped silicon dioxide nanoparticles (content increasing from 5wt% to 12wt%), which can change the propagation path of light in the plate, further achieve an anti-glare effect, and possibly optimize the optical and mechanical properties of the plate; and the inner layer is an antistatic modified PC base plate, which can prevent static electricity from accumulating on the surface of the plate, reduce dust adsorption, keep the surface of the plate clean, and help maintain its light transmission performance.

The grid-shaped supporting ribs on the bottom of the base plate 3 can significantly enhance the structural strength and stability of the base plate 3. The grid-shaped design can provide support for the base plate 3 in multiple directions, so that the sunlight plate is not easy to be damaged, such as deformation and cracking, when bearing external forces, such as wind force, snow pressure or acting force in the installation process. The stable structure not only prolongs the service life of the sunlight plate, but also ensures that the sunlight plate can normally play the functions of anti-dazzling and daylighting under various environmental conditions, provides a reliable support basis for the whole sunlight plate system, and is provided with a hollow honeycomb layer 5 on the base plate 3. The honeycomb axis of the hollow honeycomb layer 5 is inclined at an angle of 15 DEG with the base plate 3, and the inner wall of the honeycomb is coated with a 1 mu m-thick titanium dioxide scattering layer. Compared with the vertical setting, the honeycomb axis with the 15 DEG inclination can change the propagation path of light in the hollow honeycomb layer 5, so that the light in the honeycomb structure experiences more times of reflection and refraction, further disrupts the propagation direction of the light, and enhances the scattering effect of the light. The 1 mu m-thick titanium dioxide scattering layer coated on the inner wall of the honeycomb utilizes the good light scattering performance of titanium dioxide. When the light irradiates on the layer, the light can be scattered in all directions, the concentrated light is homogenized, the intensity of the light is greatly reduced, and the generation of glare is effectively reduced. Meanwhile, the inclined honeycomb structure and the titanium dioxide scattering layer synergistically act to increase the structural strength of the plate to a certain extent, and the hollow structure itself is also helpful for heat insulation, reduces heat transfer, improves the thermal comfort of an indoor space, the hollow honeycomb layer 5 is provided with a gradient refractive index composite layer 6, the outer layer of the gradient refractive index composite layer 6 is a PC base plate containing 2 wt% benzotriazole UV absorber, the middle layer is a PC base plate gradiently doped with silica nanoparticles, the content of the silica nanoparticles increases from 5 wt% to 12 wt%, and the inner layer is an antistatic modified PC base plate, and the outer layer of the PC base plate contains 2 wt% benzotriazole UV absorber and can effectively absorb ultraviolet rays.

The PC base plate of the middle layer gradiently doped with silica nanoparticles has a gradient change in refractive index due to the content of the nanoparticles increasing from 5 wt% to 12 wt%.

The gradient refractive index composite layer 6 is provided with a PC plate 4.

[0041] Example 2

[0042] To increase the incident light diffusion angle, for example, such as Figs. 1-2 As shown, this utility model also includes: a microprism array 1 disposed on a PC board 4, and the PC board 4 and the microprism array 1 are bonded together by an optically transparent adhesive layer. The refractive index of the optically transparent adhesive layer is 1.50±0.05, which plays a good connecting role. Its refractive index of 1.50±0.05 matches the refractive index of the PC board 4 and the microprism array 1. When light propagates from the PC board 4 to the microprism array 1, because the refractive index of the optically transparent adhesive layer is compatible with the materials on both sides, the light has little difference in refractive index at the interface of different media, reducing reflection and scattering losses, ensuring that the light can pass smoothly and maintaining the high efficiency of light propagation. This allows the microprism array 1 to fully utilize its refraction and reflection capabilities, thereby better achieving the anti-glare function while ensuring that the overall light transmission performance of the polycarbonate sheet remains unaffected, providing ample and soft light indoors. The microprism array 1 is an isosceles triangle with a vertex angle α = 45° ± 2°. This isosceles triangle shape allows for precise refraction and reflection of light. When light shines on the microprisms, according to the laws of refraction and reflection, the microprisms at this specific vertex angle can reflect or refract potentially glaring direct light rays at an appropriate angle to other directions, dispersing the light more evenly. Compared to other vertex angles, this angle range more effectively alters the light propagation path, reducing the amount of strong light directly entering the eyes, greatly enhancing the anti-glare effect, providing users with a more comfortable visual experience, while ensuring sufficient light transmission to maintain good lighting performance. Furthermore, the microprism array 1 is evenly distributed on the PC board 4, with a height of 0.2 mm and a spacing of 0.5 mm.

[0043] Working principle:

[0044] The light first reaches the PC sheet 4 layer of the PC sun sheet, which has a microprism array 1. As the light propagates through air, it encounters the PC sheet 4. Due to the difference in refractive index between air and PC sheet 4, the light changes its direction of propagation at a specific angle according to the law of refraction, and enters the PC sheet 4. The law of refraction states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the refractive indices of the two media.

[0045] Light rays are incident on the microprism array 1, which is composed of a large number of isosceles triangular microprisms with an apex angle a = 45° ± 2° and uniformly distributed on the surface of the PC plate 4. The microprisms use the refraction and reflection properties of light to regulate light. When light shines on the microprism, due to the special geometric shape of the microprism, the light is refracted and reflected on its surface. For direct light that can produce glare, the microprism will reflect or refract it in other directions. For example, according to the law of reflection of light, the reflected light and the incident light, the normal are in the same plane, and the reflection angle is equal to the incidence angle. By changing the propagation path of the light through reflection and refraction, the light is scattered in different directions, reducing the strong light directly entering the human eye, and achieving the initial anti-glare effect.

[0046] The light processed by the microprism passes through the optical transparent adhesive layer with a refractive index of 1.50 ± 0.05 and enters the gradient refractive index composite layer 6. The optical transparent adhesive layer plays a role in connecting the PC plate 4 and the gradient refractive index composite layer 6. When light propagates in different media, if the refractive index difference between the media is large, there will be more reflection and scattering at the interface, resulting in light loss. The refractive index of this optical transparent adhesive layer is adapted to the PC plate 4 and the gradient refractive index composite layer 6, so that when the light enters the optical transparent adhesive layer from the PC plate 4 and enters the gradient refractive index composite layer 6 from the optical transparent adhesive layer, the refractive index difference is small, reducing the reflection and scattering loss at the interface, ensuring that the light can pass smoothly and maintaining the effectiveness of light propagation.

[0047] The light enters the gradient refractive index composite layer 6 composed of an outer layer, a middle layer and an inner layer. The outer layer is a PC substrate plate containing 2wt% benzotriazole UV absorber. The molecular structure of the benzotriazole UV absorber can interact with the photons of ultraviolet light. Ultraviolet photons have high energy, and when they shine on the PC substrate plate containing benzotriazole UV absorber, the absorber molecules absorb the energy of ultraviolet light and convert it into other forms of energy, such as heat energy, thereby blocking ultraviolet light from entering the inside of the solar panel and preventing ultraviolet light from damaging the internal structure and other functional layers of the solar panel, playing a protective role for the panel.

[0048] The middle layer is a PC substrate plate doped with gradient silica nanoparticles, with a silica nanoparticle content increasing from 5wt% to 12wt%. Due to the doping of nanoparticles, the refractive index of this layer shows a gradient change. When light propagates in this gradient refractive index medium, it will constantly change the propagation direction. This is because light propagates in media with different refractive indices, and will be deflected towards the direction with a larger refractive index. In this layer, as the light propagates, the light will gradually bend and propagate along the direction of the change in refractive index due to the gradual change in refractive index, further scattering and regulating the light, making the light more uniformly distributed in the layer, reducing the possibility of glare, and optimizing the transmission efficiency of light inside the panel.

[0049] The inner layer is an antistatic modified PC base plate. The antistatic modification is realized by adding special antistatic agent or using specific modification process. The principle is to form a layer with certain conductive property on the surface of the PC base plate, which can quickly conduct the static electricity accumulated on the surface. Static electricity is easy to adsorb dust and other impurities, and the antistatic layer can avoid the dust adsorbed on the surface of the plate due to static electricity accumulation, keep the surface of the plate clean, and is conducive to the normal propagation of light, maintaining the optical performance of the solar panel.

[0050] After the light passes through the gradient refractive index composite layer 6, it enters the hollow honeycomb layer 5. The honeycomb axis of the hollow honeycomb layer 5 is inclined at an angle of 15° to the substrate 3, and the inner wall of the honeycomb is coated with a 1 μm thick titanium dioxide scattering layer. Titanium dioxide has good light scattering performance, and when light shines on the titanium dioxide scattering layer on the inner wall of the honeycomb, the light will be scattered in all directions. This scattering effect is based on the principle of light-matter interaction, and the microstructure of titanium dioxide causes the light to be reflected and refracted multiple times on its surface, thereby homogenizing the light and reducing the degree of light concentration, further reducing glare. At the same time, the hollow structure of the hollow honeycomb layer 5 can prevent heat transfer to some extent, thereby playing a role in heat insulation. Heat transfer has three ways of conduction, convection and radiation, and the poor thermal conductivity of air in the hollow structure can reduce heat conduction; and the closed hollow space is not conducive to air convection, thereby reducing the exchange of heat between the indoor and outdoor, and improving the thermal comfort of the indoor.

[0051] After the light passes through the hollow honeycomb layer 5, it reaches the substrate 3, which is provided with support ribs distributed in a grid pattern at the bottom. The substrate 3 plays a key role in supporting the entire solar panel structure. The grid-shaped support ribs enhance the strength and stability of the substrate 3, enabling the solar panel to withstand certain external forces such as wind, snow pressure, etc. When the light propagates in the substrate 3, due to the characteristics of the substrate 3 material, the light can continue to propagate, but there may be a small amount of absorption and scattering during the propagation process. However, overall, it can still ensure a certain light transmittance, and finally propagate the light that has been processed and adjusted multiple times to the other side of the solar panel, providing soft and comfortable light for the indoor.

For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and the present application can be realized in other specific forms without departing from the spirit or basic characteristics of the present application.
