TECHNICAL FIELD
[0001] The utility model belongs to light guide panel material technical field especially relates to a hollow light guide core layer and light guide type composite panel. BACKGROUND
[0002] In the field of lighting and display technology, the uniform distribution and efficient utilization of light sources have always been a hot and difficult point of research. In order to realize the uniform distribution of light, the traditional lighting or display device usually adopts the scheme of combining point light source or line light source with light guide plate. As an important optical element, the core function of light guide plate is to guide and diffuse the light emitted by the light source, thereby forming a uniform area light source. However, this traditional light guide method faces many challenges in actual application, especially in cost control and light guide effect, which is difficult to achieve the ideal balance.
[0003] The traditional light guide plate technology often needs to be punched on the surface or inside of the light guide plate. Dotting, that is, by making small concave-convex or holes on the light guide plate to change the propagation path of light, to realize the diffusion and uniform distribution of light. However, this dotting method not only increases the complexity of the production process, but also significantly increases the production cost. The position, size and density of the dotting need to be accurately controlled during the dotting process to ensure the uniformity of the light guide effect, which undoubtedly puts forward very high requirements for the precision of the production equipment and the skill of the operator. At the same time, the dotting process may have a negative impact on the light transmittance and durability of the light guide plate, reducing the overall performance of the product.
[0004] In addition, the combination scheme of traditional light guide plate and light diffusion plate, although it realizes the uniform distribution of light to a certain extent, the combination between the two often needs additional bonding or fixing process, which not only increases the weight and thickness of the product, but also may introduce additional optical interface, causing loss and scattering of light during propagation, further affecting the light guide effect and energy efficiency ratio.
[0005] In view of the limitations of the above-mentioned traditional technology, the industry has been exploring more efficient and low-cost light guide and light diffusion solutions. Especially in the background of the increasing popularity of LED and other solid-state lighting technologies, the demand for optical elements that can realize efficient light guide and uniform light distribution is increasingly urgent. Therefore, developing a new type of light guide material or structure that can save the traditional dotting method while having good light guide effect and cost benefit has become a technical problem to be solved in the current lighting and display technology field.

[0024] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the following will be further described in detail by combining with the embodiment. It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the utility model.
[0025] Embodiment 1, please refer to Figure 1 A hollow light guide core layer, comprising a light guide honeycomb plate 1 made of transparent or translucent material, the light guide honeycomb plate comprises a double-layer honeycomb layer integrally injection molded, and the honeycomb chambers of the double-layer honeycomb layer are staggered, the light guide honeycomb plate is provided with a light emitting element 2, and the parallel light emitted by the light emitting element enters the light guide honeycomb plate.
[0026] The above-mentioned light guide honeycomb plate can be injection molded into a large plate, or can be formed by splicing a plurality of double-layer honeycomb monomers.
[0027] The core of the utility model lies in that the light guide honeycomb plate made of transparent or translucent material realizes efficient light guide and uniform distribution of light source through precise geometric structure design. The following is a detailed analysis of the light guide principle of the utility model:
[0028] Hollow light guide core layer design:
[0029] The light guide honeycomb plate of the utility model adopts a hollow design, that is, there are cavities or honeycomb chambers in the honeycomb layer, and these honeycomb chambers constitute the channel for light propagation.
[0030] The honeycomb chamber is preferably hexagonal, which not only has good structural stability, but also effectively guides the light to reflect and refract multiple times within the honeycomb chamber.
[0031] The honeycomb chambers of the double-layer honeycomb layer are staggered, which further increases the propagation path of light within the honeycomb panel, allowing the light to be more fully diffused and uniformized.
[0032] Propagation of light within the core layer:
[0033] When the parallel light emitted by the light-emitting element enters the light guide honeycomb panel, the light first enters the entrance end of the honeycomb chamber.
[0034] Due to the hollow design of the honeycomb chamber, the light reflects and refracts on the continuous inner wall of the honeycomb chamber. Reflection allows the light to continue to propagate along the wall of the honeycomb chamber, while refraction changes the direction of the light, allowing the light to diffuse in all directions of the honeycomb panel. Through multiple reflections and refractions, the light forms a complex light path within the honeycomb panel, which interweaves with each other, and finally realizes the uniform distribution of light.
[0035] Consideration of the scattering properties of light:
[0036] The structure design of the honeycomb panel of the utility model fully considers the scattering properties of light, and the staggered double-layer honeycomb layer allows the light to intersect with other honeycomb chambers more during propagation, thereby increasing the diffusion opportunity and uniformity of the light. It can make the light form a uniform light field inside the honeycomb panel.
[0037] The hollow light guide honeycomb panel design of the utility model brings significant technical effects, mainly in the following aspects:
[0038] Efficient light guiding and uniform distribution:
[0039] Through precise geometric structure design, the utility model realizes efficient light guiding of the light source. The light propagates in the honeycomb panel through multiple reflections and refractions, and can fully utilize the space of the honeycomb chamber.
[0040] At the same time, the utility model also realizes the uniform distribution of light. Due to the hollow design of the honeycomb panel and the optimized size, shape and arrangement of the honeycomb unit, the light forms a uniform light field inside the honeycomb panel, avoiding the bright spots or dark areas that may occur in traditional light guiding methods.
[0041] Simplify production process and reduce cost:
[0042] The light guide honeycomb panel of the utility model is manufactured by integral injection molding technology, which simplifies the production process. Compared with the traditional dotting method, the hollow design does not require additional processing steps or materials, thereby reducing production costs.
[0043] One-piece injection molding also ensures the structural stability and consistency of the honeycomb plate, improving the quality and reliability of the product.
[0044] Good mechanical strength and durability:
[0045] Due to the double-layer honeycomb design of the honeycomb plate, and the staggered arrangement of the honeycomb chambers, this structure gives the product good mechanical strength. Even under external force, the honeycomb plate can maintain the integrity of the structure and is not easy to deform or break.
[0046] At the same time, the transparent or translucent material is selected from any one of PMMA (polymethyl methacrylate), PC (polycarbonate), PS (polystyrene) and PP (polypropylene) with good haze (not limited to this) as the light guide honeycomb plate of the transparent or translucent material. The technical effects mainly reflect in the following aspects: first, these materials have good light transmission, which can ensure the effective propagation of light in the light guide honeycomb plate. At the same time, their excellent haze characteristics make the light scattering moderate during transmission, which helps to achieve uniform distribution of light and avoid the appearance of bright spots or dark areas, improving the uniformity and consistency of the lighting or display effect. Secondly, these materials have good processing performance and can be integrally formed into a light guide honeycomb plate through injection molding and other processes, simplifying the production process and reducing production costs. In addition, PMMA, PC and other materials also have good weather resistance and mechanical strength, which can ensure that the light guide honeycomb plate maintains stable performance in various environments and prolongs the service life. In summary, the selection of these materials to make light guide honeycomb plates can achieve efficient and uniform light guide effect while ensuring the economy and durability of the product.
[0047] In summary, the hollow light guide honeycomb plate of the present utility model realizes efficient light guide and uniform distribution of light sources through precise geometric structure design, simplifies the production process, reduces production costs, and gives the product good mechanical strength and durability. These technical effects make the light guide honeycomb plate of the present utility model have wide application prospects in the field of lighting and display technology, and inject new vitality into the upgrading and development of related industries.
[0048] Preferably, the light emitting element is arranged on any one side or adjacent two sides or opposite two sides of the light guide honeycomb plate. By flexibly arranging the light emitting element on any one side or adjacent two sides or opposite two sides of the light guide honeycomb plate, light input in different directions can be realized, meeting diversified lighting or display needs. This design improves the applicability and flexibility of the light guide honeycomb plate, making the light more evenly distributed inside the honeycomb plate, further improving the light guide effect and visual experience. This embodiment arranges one side.
[0049] Embodiment 2, please refer to Figure 2The light guide honeycomb plate is provided with a groove 1-1, and a light emitting element 2 is installed in the groove. The design of the groove provides a flexible light emitting element installation mode for the large plate light guide honeycomb plate. When the side light source cannot meet the lighting requirements, the light emitting element installed through the groove can effectively supplement the light source. This design improves the flexibility and practicability of light source arrangement, ensures that the light can uniformly and fully irradiate the inside of the light guide honeycomb plate, and improves the light guide effect.
[0050] Preferably, two light emitting elements 2 with opposite irradiation directions are installed in the groove. The design of the bidirectional irradiation light emitting element further enhances the uniform distribution of light, avoiding the uneven light phenomenon that may be caused by unilateral irradiation. At the same time, this design also improves the light energy utilization rate, so that the light guide honeycomb plate performs better in lighting or display applications.
[0051] Please refer to Figure 3 The utility model also relates to a light guide type composite panel, including base plate, the base plate adopts the above hollow light guide core layer, and the at least one surface of the light guide honeycomb plate of hollow light guide core layer is compounded with the light -transmitting adhesive layer, and the light -transmitting decorative surface layer 5 is compounded and bonded on the light -transmitting adhesive layer side. First, by adopting the hollow light guide core layer as the base plate, the composite panel has good light guide performance. The hollow design not only reduces the weight of the panel, but also improves the light transmittance and uniformity, so that the light can effectively propagate inside the panel.
[0052] Secondly, the at least one surface of the light guide honeycomb plate is compounded with the light -transmitting adhesive layer, which enhances the adhesion between the light guide core layer and the decorative surface layer, and ensures the structural stability of the composite panel. At the same time, the light -transmitting adhesive layer can also maintain the light transmittance of the panel, without affecting the propagation effect of the light.
[0053] Finally, the light -transmitting decorative surface layer is compounded and bonded on the light -transmitting adhesive layer side, which not only gives the light guide type composite panel an attractive appearance, but also realizes multiple improvements in function. When the light is input into the hollow light guide core layer, the light -transmitting decorative surface layer becomes the stage for the light to show.
[0054] The light -transmitting decorative surface layer can clearly show the propagation trajectory of the light in the light guide core layer, so that the panel presents a unique visual effect. If the surface of the decorative surface layer is printed with exquisite patterns or textures, these patterns or textures will be more vivid and stereoscopic under the reflection of the light, bringing visual enjoyment to the observer. The perfect combination of light and patterns not only enhances the decorative nature of the panel, but also improves its artistic value.
[0055] More importantly, the light-transmitting decorative surface layer and the light-guiding core layer cooperate with each other to form an even better light-guiding effect. The decorative surface layer can guide the light to be evenly distributed on the surface of the panel, avoiding the situation of too concentrated or scattered light, so that the entire panel presents a soft and uniform light effect. This light distribution not only improves the lighting performance of the panel, but also makes it perform well in display applications, and can clearly display image or text information.
[0056] In addition, the light-transmitting decorative surface layer also plays a role in protecting the light-guiding core layer. As the outermost layer of the panel, it can effectively isolate harmful substances such as dust and moisture in the external environment, preventing them from damaging the light-guiding core layer, thereby prolonging the service life of the composite panel.
[0057] Preferably, the other side of the light-guiding honeycomb panel is composite bonded with a non-light-transmitting backing surface layer 6. This technical feature effectively blocks the light leakage, enhances the light-guiding effect, and protects the internal light-guiding structure from external influences, improving the overall stability and durability of the composite panel.
[0058] Preferably, the upper surface of the light-guiding honeycomb panel is composite with a light-transmitting non-woven fabric 3, and the surface of the light-transmitting non-woven fabric is bonded with a decorative surface layer through a light-transmitting adhesive layer. The light-transmitting non-woven fabric serves as a bonding link, not only has good light-transmitting property to ensure smooth transmission of light between the light-guiding honeycomb panel and the decorative surface layer, but also exhibits excellent compatibility, which is conducive to the composite of decorative surface layers of different materials. The light-transmitting non-woven fabric is tightly welded with the light-guiding honeycomb panel by using ultrasonic welding technology, which not only improves the firmness of the composite structure, but also retains the original characteristics of the light-transmitting non-woven fabric, such as softness and air permeability. This welding method avoids the light loss and pollution problems that may be caused by traditional adhesives, ensuring the overall optical performance of the composite panel.
[0059] At the same time, the surface of the light-transmitting non-woven fabric is bonded with a decorative surface layer through a light-transmitting adhesive layer, further enhancing the aesthetics and practicality of the panel. The decorative surface layer can be customized with different colors, patterns and textures according to requirements, perfectly integrated with the light-transmitting non-woven fabric and the light-guiding honeycomb panel, and exhibits a unique visual effect. In addition, the presence of the light-transmitting non-woven fabric also increases the level and three-dimensionality of the panel, enhancing the overall design and quality
[0060] Preferably, the bottom surface of the light-guiding honeycomb panel is composite with a non-woven fabric 4, and the surface of the non-woven fabric is bonded with a backing surface layer. The non-woven fabric serves as a buffer layer between the light-guiding honeycomb panel and the backing surface layer, has good air permeability and flexibility, and can effectively alleviate the panel deformation caused by temperature changes or external forces, protecting the light-guiding honeycomb panel from damage. The bonding of the backing surface layer further enhances the structural stability of the composite panel, improving its impact resistance and compression resistance.
[0061] Preferably, the upper surface of the backing layer is a light-reflecting surface. The light-reflecting surface can effectively reflect the light transmitted from the light guide honeycomb panel, so that the light reenters the light guide structure and is used again. This design not only improves the utilization rate of light, but also enhances the light guide effect of the composite panel, so that the light is more evenly distributed inside the panel, avoiding light leakage and waste.
[0062] Preferably, the decorative surface layer is a roll material with a decorative pattern or a light-transmitting panel.
[0063] This design greatly enriches the visual effect and decoration of the lightweight light guide type composite panel.
[0064] The decorative surface layer is the outermost layer of the composite panel, and directly determines the overall appearance of the panel. Using a roll material with a decorative pattern, such as PVC roll material with exquisite patterns or PET roll material with artistic patterns, can easily achieve personalized customization and meet the aesthetic needs of different customers. These roll materials not only have rich colors and various patterns, but also have good flexibility and processability, which is convenient for cutting and fitting, making the appearance of the composite panel more beautiful and unique.
[0065] On the other hand, light-transmitting panels such as light-transmitting stone, acrylic panels or glass panels, not only provide a more transparent and bright visual effect for the composite panel, but also form a good light interaction with the light guide honeycomb panel, so that the light is refracted and reflected inside the panel, forming a unique light and shadow effect. For example, light-transmitting stone not only has the texture and texture of natural stone, but also can transmit light, so that the panel exhibits fascinating light and shadow changes under light irradiation; acrylic panels have good light transmission and plasticity, providing more design possibilities for the composite panel.
[0066] In summary, the diversified selection of the decorative surface layer not only improves the decoration of the composite panel, but also enhances its visual effect and practicality, making the lightweight light guide type composite panel have a wider application prospect in lighting, decoration, display and other fields.
[0067] The above description is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
