Description

Quantum light panel This invention relates to a quantum light decorative panel, and more particularly to a quantum light decorative panel in which, when illuminated by a light source, the quantum dot material and any one or a combination of the constituent structures present a decorative pattern that differs from the original visual effect of the quantum light decorative panel. Illuminated decorative panels have a wide range of applications, including architectural lighting, commercial applications, interior decoration, traffic signs, and industrial or commercial uses in art and design. These decorative materials with light effects bring creativity and visual appeal to various occasions. In existing decorative panels, light-emitting diodes (LEDs) are commonly used as the light source. While LEDs offer advantages such as small size, low power consumption, long lifespan, high brightness, and active light emission, the color of the emitted light is often limited by the color of the light source. Therefore, many technologies attempt to alter the color by adding translucent color films, but this significantly reduces the light intensity. Consequently, the development of LEDs for decorative panel applications is relatively limited. Using light-emitting diodes (LEDs) as the light source for decorative panels, the range of colors that can be displayed is often limited by the LED or the filter layer, and they can mostly only display high color temperatures. However, when decorative panels are applied to art, high-end architecture (such as luxury homes or hotels), futuristic vehicles, or religious settings, they cannot achieve the desired visual effect, making them unsuitable for luxurious, sophisticated, futuristic, or solemn products. In other words, traditional decorative panels have certain limitations in their expressiveness and are relatively limited in their application to specific occasions. The present invention provides a quantum light decorative panel, comprising a substrate, at least one decorative layer, at least one pattern, at least one quantum dot material, and a light source. The at least one decorative layer is disposed on the substrate. The at least one pattern is included in each of the at least one decorative layer, and the at least one quantum dot material is doped or coated in any one or a combination of the substrate, the at least one decorative layer, and the at least one pattern. The light source illuminates the at least one quantum dot material, so that the at least one quantum dot material, together with any one or a combination of the substrate, the at least one decorative layer, and the at least one pattern, together present a decorative pattern. The above brief description of the present invention is intended to provide a basic explanation of several aspects and technical features of the invention. This brief description is not a detailed account of the invention, and therefore its purpose is not to specifically list the key or important elements of the invention, nor to define the scope of the invention, but merely to present several concepts of the invention in a concise manner. 10: Quantum Light Panel 100:Substrate 200a: Decorative layer 200b: Decorative layer 300: Pattern 300a: Drawing 300b: Pattern 400:Quantum dot materials 400a: Quantum dot material 400b: Quantum dot materials 400c: Quantum dot materials 500: Light source 600: Bridge Layer 700: Protective layer D: Decorative patterns Figure 1 is a structural schematic diagram of an embodiment of the quantum light decorative panel of the present invention.

To understand the technical features and practical effects of the present invention, and to implement it according to the contents of the specification, the preferred embodiments shown in the figures are further described in detail below: Please refer to Figure 1, which is a structural schematic diagram of an embodiment of the quantum light decorative panel of the present invention. As shown in Figure 1, the quantum light decorative panel 10 includes a substrate 100, a decorative layer 200a, a decorative layer 200b, a pattern 300a, a pattern 300b, a quantum dot material 400a and a quantum dot material 400b, and a light source 500. Decorative layers 200a and 200b are sequentially formed and disposed on the substrate 100. Patterns 300a and 300b are sequentially contained within decorative layers 200a and 200b. Quantum dot materials 400a and 400b can be doped or coated onto any one or a combination of the substrate 100, decorative layers 200a and 200b, and patterns 300a or 300b. In the embodiment of FIG. 1, quantum dot materials 400a and 400b are sequentially coated onto patterns 300a and 300b and contained within decorative layers 200a and 200b. In this embodiment, the light source 500 can emit light to illuminate the quantum dot materials 400a and 400b, causing the quantum dot materials 400a and 400b to emit their own excitation light. Finally, the decorative pattern D is presented together with any one or a combination of the substrate 100, decorative layer 200a, decorative layer 200b, pattern 300a or pattern 300b (refer to Figures 5, 7 or 9 first). In this embodiment, the substrate 100 is composed of, but is not limited to, transparent materials, metallic materials, and combinations thereof. Specifically, when the substrate 100 is made of a transparent material, the relevant transparent material may include sapphire, glass (SiO2), etc. 2) Materials include quartz, ceramic, epoxy resin, acrylate, polyimide, polymethylmethacrylate (PMMA), polyethylene terephthalate (PET), polycarbonate (PC), polydimethylsilicon (PDMS), zinc oxide (ZnO), aluminum nitride (AlN), or silicon carbide (SiC). The metal substrate 100 can be selected from metals, alloys, or other materials that exhibit light-reflecting effects; this invention is not limited in these categories. Furthermore, the decorative layer 200a or decorative layer 200b in this embodiment can also be composed of transparent material, metallic material, or a combination thereof. Specifically, the decorative layer 200a and decorative layer 200b used in the embodiment of FIG1 are made of transparent material (which may be the same as or different from the substrate 100), and the patterns 300a and 300b are suspended and embedded therein. Next, quantum dot materials 400a and 400b are partially / completely doped or coated on patterns 300a and 300b, and are contained in the decorative layer 200a or decorative layer 200b. In this embodiment, although patterns 300a and 300b are depicted as flat, they can actually be made into relief patterns through various processes, including but not limited to printing, inkjet printing, overlaying, engraving, and 3D printing, giving patterns 300a or 300b a three-dimensional visual effect. Furthermore, patterns 300a and 300b in this embodiment can also be mixed with or added with inks, dyes, fluorescent powders, metallic powders, and combinations thereof to meet various application requirements, and this invention does not impose any limitations. Finally, the purpose of the light source 500 in this embodiment is to excite the quantum dot material 400a or 400b to produce a corresponding optical visual effect. Accordingly, the light source 500 in this embodiment can be selected from any lighting or light-emitting device that includes an ultraviolet light source (such as a light-emitting diode containing an excitation wavelength). In this embodiment, the wavelength range of the ultraviolet light source selected for the light source 500 is preferably between 315 and 400 nanometers. Furthermore, in embodiments under the concept of the present invention, the number of light sources 500 is not limited, but only needs to be selected according to the visual requirements or the type of excitation conditions (such as brightness or color wavelength) required for the quantum dot material 400a or 400b. Furthermore, in addition to ultraviolet light sources, the light source 500 can also be equipped with infrared light sources or visible light sources. Depending on whether the quantum dot material 400a or 400b is used, different light sources 500 can be selected to meet different situational needs, allowing the quantum light decorative panel 10 to have various visual or optical effects. In this embodiment, quantum dot material 400a or quantum dot material 400b is selected from the chemical formula MAX. 3. Perovskite quantum dots. When quantum dot material 400a or quantum dot material 400b is selected from the chemical formula MAX When using 3 perovskite quantum dots, M is a cation, A is a metal ion, and X is a halide ion. In other possible embodiments, the quantum dot material 400a or quantum dot material 400b may also be selected from cadmium sulfide (CdS), cadmium selenide (CdSe), cadmium telluride (CdTe), zinc sulfide (ZnS), zinc selenide (ZnSe), zinc telluride (ZnTe), mercuric sulfide (HgS), mercuric selenide (HgSe), mercuric telluride (HgTe), gallium nitride (GaN), gallium phosphide (GaP), gallium arsenide (GaAs), indium phosphide (InP), indium arsenide (InAs), and combinations thereof, selected only according to the actual optical or visual requirements of the quantum light decorative panel 10, and the present invention is not limited thereto. Accordingly, through the aforementioned mechanism, the light source 500 can adjust whether or not the quantum dot material 400a or quantum dot material 400b should be excited, and the intensity of that excitation, by adjusting parameters such as its quantity, type, or irradiation intensity (brightness). This mechanism allows the quantum light panel 10 to possess numerous means for manually adjusting visual or optical changes, facilitating its application in a wide variety of situations. Further, please refer to Figure 2, which is a structural schematic diagram of another embodiment of the quantum light decorative panel of the present invention. The difference between Figure 2 and the embodiment of Figure 1 is that the pattern 300b in the embodiment shown in Figure 2 is not embedded in the decorative layer 200b made of transparent material in the embodiment of Figure 1. In this embodiment, the decorative layer 200b is a rough regional functional concept; in fact, the decorative layer 200b is a three-dimensional printed relief simply by printing the pattern 300b directly onto the transparent decorative layer 200a. Furthermore, in the embodiment of Figure 2, to achieve a more stable bond between the transparent decorative layer 200a and the substrate 100, a cross-linking layer 600 is included between the substrate 100 and the decorative layer 200a. In this embodiment, the cross-linking layer 600 is a cross-linking agent. The cross-linking agent is a surface treatment agent, modifier, or primer. The cross-linking agent allows the main chain molecules of the material to bridge each other, enabling multiple linear molecules to bond together, forming covalent or ionic bonds and cross-linking into a network structure, which allows the decorative layer 200a to adhere more effectively to the substrate 100. The type of cross-linking agent selected in the embodiments of this invention is not particularly limited, and suitable or commonly used cross-linking agents can be appropriately selected. For example, the cross-linking agent may include polyisocyanate compounds, epoxy resins, melamine resins, urea resins, dialdehyde compounds, hydroxymethyl polymers, etc., but is not limited to these. Preferably, the use of polyisocyanate compounds is a preferred choice in this embodiment. Given that the embodiment in Figure 2 includes an additional bridging layer 600, in other possible embodiments of the present invention, the bridging layer 600 may be doped or coated with quantum dot material 400a or quantum dot material 400b, and the present invention does not impose any limitations on this. Please refer to Figure 3, which is a structural schematic diagram of another embodiment of the quantum light decorative panel of the present invention. As shown in Figure 3, the difference between the embodiment shown in Figure 3 and the embodiment shown in Figure 1 is that the embodiment in Figure 3 has a protective layer 700 formed outside the decorative layer 200a, decorative layer 200b, and substrate 100. In other possible embodiments under the concept of the present invention, the protective layer 700 may also cover only a portion of the decorative layer 200a, decorative layer 200b, or substrate 100 as needed, and the present invention is not limited thereto. Specifically, the protective layer 700 in this embodiment can also be additionally doped or coated with quantum dot material 400c, so that this embodiment can not only have additional optical or visual effects, but also achieve a protective function. In this embodiment, the material of quantum dot material 400c can be the same as or different from that of quantum dot material 400a and quantum dot material 400b. As for the material of the protective layer 700, the material of the protective layer 700 in this embodiment can be silicon dioxide, silicon nitride, polyurethane, natural lacquer, or epoxy resin, etc., selected only according to actual needs, and the present invention does not impose any limitations. Similarly, in possible embodiments of the present invention, the surface of the protective layer 700 can also be processed into various shapes with different undulations through grinding, engraving, or laser processing. For example, processing it into a surface treatment with a hairline texture can bring different visual effects. Furthermore, the protective layer 700 can also be processed into various structures or microstructures that can affect the optical light emission effect, such as reflective, scattering, or light guiding; and the same surface processing concept can also be applied to the decorative layer 200a or decorative layer 200b, and the present invention is not limited thereto. Next, please refer to Figures 4 and 5 simultaneously. Figure 4 is a schematic diagram of an embodiment of the quantum light decorative panel of the present invention when it is not illuminated by a light source; Figure 5 is a schematic diagram of a decorative pattern of an embodiment of the quantum light decorative panel of the present invention that exhibits shape differences after being illuminated by a light source. In Figure 4, the pattern 300 on the quantum light decorative panel 10 is in principle a black triangle. Once the quantum light decorative panel 10 is illuminated by the light source 500 as shown in Figure 5, the original pattern 300 and the excited quantum dot material 400 together form a six-pointed star-shaped decorative pattern D. Accordingly, in this embodiment, the decorative pattern D and the original pattern 300 have a visual difference in shape. Please refer to Figures 6 and 7 simultaneously. Figure 6 is a schematic diagram of another embodiment of the quantum light decorative panel of the present invention when it is not illuminated by a light source; Figure 7 is a schematic diagram of a decorative pattern of an embodiment of the quantum light decorative panel of the present invention that presents color differences after being illuminated by a light source. In Figure 6, the pattern 300 on the quantum light decorative panel 10 is in principle shaped like a five-petaled flower. Once the light source 500 is irradiated onto the quantum light decorative panel 10 as shown in Figure 7, the quantum dot material 400 originally doped or coated in the pattern 300 will collectively form a decorative pattern D with a new color. Accordingly, in this embodiment, the decorative pattern D and the original pattern 300 have a visual difference in color through this method. Finally, please refer to Figures 8 and 9 simultaneously. Figure 8 is a schematic diagram of another embodiment of the quantum light decorative panel of the present invention when it is not illuminated by a light source; Figure 9 is a schematic diagram of a decorative pattern of an embodiment of the quantum light decorative panel of the present invention that presents different patterns after being illuminated by a light source. In Figure 8, the pattern 300 on the quantum light decorative panel 10 is, in principle, in the form of white clothing. Once the light source 500 is irradiated onto the quantum light decorative panel 10 as shown in Figure 9, the quantum dot material 400, which is originally doped or coated within the pattern 300 and then excited, will display a special pattern, together forming a decorative pattern D with a new pattern. Accordingly, in this embodiment, the decorative pattern D and the original pattern 300 have a visual difference in pattern through this method. The differences in visual effects of the decorative pattern D presented in the embodiments shown in Figures 4 to 9 can be achieved by varying the type and quantity of the light source 500, as well as the type, quantity, and doping or coating of the quantum dot material 400 on the different layers or positions of the quantum light decorative panel 10. Through this method, users can adjust the optical or visual effects of the quantum light decorative panel 10 according to different needs or occasions, maximizing its practicality, aesthetics, and adjustability. However, the above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. Any simple changes and modifications made in accordance with the scope of the patent application and the description of the present invention shall still fall within the scope of the present invention. 10: Quantum Light Panel 100:Substrate 200a: Decorative layer 200b: Decorative layer 300a: Drawing 300b: Pattern 400a: Quantum dot material 400b: Quantum dot materials 500: Light source
