[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0025] Example 1
[0026] This embodiment provides a luminescent decorative composite panel, primarily but not limited to applications as a concealable starry sky decorative composite panel based on fiber optic light emission. It is suitable for dynamic starry sky ceilings, smart background walls, cabinet back panels, space partitions, furniture, and other scenarios, achieving seamless switching between light effects and decorative surfaces. Figure 1 and Figure 2 As shown, the system includes a substrate 1, an optical transmission intermediate layer 2, and a surface decoration film layer 3, which are fixedly arranged from top to bottom. The substrate 1 has multiple through-holes for light transmission. The number and position of the through-holes are set according to the desired light-emitting pattern, and each through-hole contains a light-emitting element. The optical transmission intermediate layer 2 is a transparent layer, and the upper surface of the optical transmission intermediate layer 2 can block the lower opening of each through-hole. The surface decoration film layer 3 covers the lower surface of the optical transmission intermediate layer 2, and the light emitted by each light-emitting element can pass through the optical transmission intermediate layer 2 and the surface decoration film layer 3 in sequence. When the light-emitting element is powered off and does not emit light, the surface decoration film layer 3 can visually cover each through-hole.
[0027] A composite panel structure is formed by sequentially fixing a substrate 1, an optically conductive intermediate layer 2, and a surface decorative film layer 3. The materials of each layer work together to give the composite panel a certain strength and stability, making it suitable for various applications such as wall decoration, ceiling decoration, and furniture surface decoration. The surface decorative film layer 3 not only allows light to pass through but also visually covers the light-transmitting holes when the light-emitting element is powered off, keeping the decorative panel surface intact and aesthetically pleasing. Whether the lights are on or off, it blends seamlessly with the surrounding environment, enhancing the overall decorative effect. The decorative film also serves as a protective layer, preventing... The optical transmission intermediate layer 2 and the light-emitting element are protected from external physical damage, such as scratches and collisions. It also reduces the erosion of dust and moisture, extending the service life of the luminous decorative composite board. The optical transmission intermediate layer 2 is a transparent layer, which can effectively conduct and uniformly scatter the light emitted by the light-emitting element, so that the light presents a soft and uniform luminous effect after passing through the surface decorative film layer 3, enhancing the visual experience. The number and position of the light-transmitting holes on the substrate 1 can be set according to the required luminous pattern, which can meet the diverse luminous design needs in different scenarios and achieve various unique and personalized luminous effects.
[0028] The following are the settings for substrate 1:
[0029] In the optional solutions of this embodiment, the substrate 1 is preferably a PVC foam board, a carbon crystal board, or a high-density fiberboard. Compared with traditional gypsum board, sound-absorbing board, or honeycomb board, the use of PVC foam board, carbon crystal board, or high-density fiberboard provides better strength and stability, better waterproof and moisture-proof performance, and simpler and more convenient processing and installation.
[0030] In the optional solutions of this embodiment, the preferred choice is an optical fiber as the light-emitting element. When the light-emitting element is an optical fiber, the resulting decorative composite panel is based on optical fiber light emission, which is existing technology. Optical fibers have excellent light transmission characteristics, enabling efficient transmission of light emitted by the light source to various parts of the composite panel, achieving a uniform light emission effect. The light emitted by optical fibers is relatively soft and does not produce glare, creating a comfortable and warm lighting environment. This soft light has unique advantages in the decoration field and is suitable for various places that require creating a specific atmosphere. Optical fibers have low loss during light transmission, achieving high luminous efficiency with low energy consumption. Compared with some traditional light-emitting elements, such as incandescent lamps and fluorescent lamps, they have significant energy-saving advantages, helping to reduce energy consumption and operating costs. Optical fibers do not contain harmful substances such as mercury and lead, and will not cause environmental pollution during production, use, and disposal, meeting the requirements of modern society for environmentally friendly materials.
[0031] In the optional solutions of this embodiment, it is more preferred that each light-transmitting hole on the substrate 1 can form a dotted, pentagonal, or linear pattern. The pattern formed by each light-transmitting hole on the substrate 1 can be set as needed. For example, when it is used as a starry sky decorative composite panel, the dotted pattern can create a simple and exquisite effect, like twinkling stars, adding a touch of delicacy and dynamism to the space; the pentagonal pattern has unique decorative and symbolic meaning, which can give the space a unique atmosphere, such as enhancing the theme atmosphere in some places with a specific theme style; the linear pattern can be a smooth curve or a straight line. Curves can bring a soft and elegant feeling, while straight lines reflect a simple and modern style. Through different combinations and arrangements of lines, a visual effect with rhythm and cadence can also be created.
[0032] The following are the specifications for the optical transmission intermediate layer 2:
[0033] In the optional solutions of this embodiment, the optical transmission intermediate layer 2 is preferably an acrylic sheet or a polycarbonate sheet. Acrylic sheets have high transparency, with a light transmittance of over 92%, which can effectively transmit light, making the luminous decorative composite panel's luminous effect uniform, soft, and brightly colored, accurately presenting the color and brightness of the light emitted by the optical fiber. Polycarbonate sheets have several times the impact resistance of acrylic sheets, good toughness, and are not easily broken or damaged, effectively protecting the internal optical fibers and other structures, making the luminous decorative composite panel more impact-resistant during installation and use. Moreover, compared to the traditional single-material substrate 1, its bending strength is improved, making it suitable for ceilings, background walls, cabinet back panels, space partitions, furniture, and other scenarios. It can also be applied to curved walls to create various irregular shapes.
[0034] In the optional solutions of this embodiment, the preferred option is that the light transmittance of the optical transmission interlayer 2 is ≥91%. High light transmittance allows light emitted from the optical fiber to pass through the interlayer to the maximum extent, reducing light loss during transmission and thus improving the overall luminous efficiency of the composite board. This makes the surface luminous effect brighter and clearer, better meeting decorative and lighting needs. It also ensures uniform light propagation within the interlayer, resulting in more uniform luminous emission from the composite board surface, avoiding uneven brightness and improving the quality of the visual effect, creating a comfortable and soft lighting atmosphere for the space. Furthermore, it allows various color components in the light to pass through smoothly, reducing color distortion or deviation caused by insufficient light transmittance, making the luminous color of the composite board purer and more vibrant, better showcasing the desired color effect and enhancing the aesthetics and attractiveness of the decoration.
[0035] The following are the relevant settings for the surface decorative film layer 3:
[0036] In the optional solutions of this embodiment, the more preferred option is that the surface decorative film layer 3 is a decorative film with a solid color, wood grain, stone, metallic texture, or mirror finish. It can achieve a soft, non-glaring starry sky effect. The decorative film can be customized according to the specific needs of the customer, including color, pattern, and size, meeting the personalized decoration requirements of different customers and achieving unique design effects. Compared with using real wood, stone, or metal to achieve the same decorative effect, the cost of using decorative film is much lower. Furthermore, it can be assembled through thermoforming, making installation simpler and faster, thus reducing decoration costs and construction difficulty while ensuring the decorative effect.
[0037] Regarding other related settings:
[0038] In the optional solutions of this embodiment, it is more preferred that the thickness of the substrate 1 is 8mm to 18mm; the thickness of the optical transmission intermediate layer 2 is 1.5mm to 3mm; and the thickness of the surface decorative film layer 3 is about 20 mils (about 0.2mm). The substrate 1, with a thickness between 8mm and 18mm, provides a robust support structure for the composite panel, ensuring it is not easily deformed during installation and use. A thicker substrate 1 can withstand greater external forces, reducing the risk of damage caused by external pressure, collisions, etc., making it suitable for various installation environments, whether on walls or ceilings, ensuring the integrity and stability of the composite panel. The appropriate thickness gives the substrate 1 a certain strength and toughness, better protecting the internal optical transmission intermediate layer 2 and light-emitting elements in the event of accidents such as earthquakes or object impacts, reducing safety hazards and ensuring safe use. The optical transmission intermediate layer 2, with a thickness between 1.5mm and 3mm, can reduce light scattering and loss during transmission while ensuring light transmission. This thickness range allows light to propagate efficiently in the intermediate layer, uniformly transmitting the light emitted by the light-emitting elements to the surface of the composite panel, achieving good light emission effects and improving light utilization. The surface decorative film layer 3, with a thickness of about 20 mils (0.2mm), can present various decorative effects well.
[0039] In the optional embodiments of this example, a preferred method is to bond the substrate 1 to the optically conductive intermediate layer 2 via an adhesive layer. The adhesive layer provides reliable bonding force, ensuring a tight bond between the substrate 1 and the optically conductive intermediate layer 2, preventing relative displacement or separation. The bonding process is relatively simple, easy to operate and control, and can adapt to the connection requirements of substrates 1 and optically conductive intermediate layers 2 of different shapes and sizes. Whether it is a planar or curved composite board, a good connection can be achieved through a suitable bonding process, which can improve production efficiency and reduce production costs during the production process. High-quality adhesive layers typically have good optical properties, with minimal absorption and scattering of light.
[0040] In the optional embodiments of this example, the adhesive layer is preferably formed by curing PET adhesive. PET adhesive has high light transmittance and low haze, which can effectively reduce the absorption and scattering of light, thus contributing to a high-quality luminescence effect.
[0041] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
