Technical Field

[0001] This utility model relates to the field of metal technology, specifically to a metal ornament. Background Technology

[0002] Traditional metal jewelry is typically decorated only through surface engraving and gemstone inlay, resulting in relatively simple patterns and visual effects that fail to meet consumers' growing demands for personalized and diverse aesthetics. With the application of optical technology in the jewelry industry, some jewelry with optical effects has gradually emerged. However, most existing optical jewelry can only achieve a single optical effect, such as producing fixed patterns solely through optical reflection or diffraction. They lack the design and innovation of combining multiple optical effects, thus failing to provide consumers with a rich visual experience. Utility Model Content

In the detailed description of the present application below, certain specific details are described in detail. Those skilled in the art can fully understand the present application without these details. To avoid obscuring the substance of the present application, well-known methods, processes, flows, elements, and circuits are not described in detail.

[0018] Furthermore, those skilled in the art should understand that the accompanying drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale.

[0019] Unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0020] Unless the context explicitly requires it, words such as "including" or "contains" throughout the application should be interpreted as including rather than exclusive or exhaustive; that is, meaning "including but not limited to".

[0021] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0022] The metal ornament of this application includes a body 10, on which a first optical microstructure and a visible structure are provided. The first optical microstructure includes micro-nano uneven units, which can form a first pattern 11 through optical effects under the illumination of incident light. The visible structure forms a second pattern 12 through optical effects under the illumination of incident light.

[0023] Specifically, the first optical microstructure can be formed by die stamping or by laser engraving to form micro-nano uneven units with a predetermined arrangement and depth. The characteristic size of the micro-nano uneven units is usually between tens of nanometers and several micrometers, which is much smaller than or close to the wavelength of visible light. The first optical microstructure on the surface of the metal ornament 10 cannot be directly distinguished by the naked eye. Therefore, the overall appearance of the first optical microstructure is smooth or mirror-like.

[0024] Under incident light, micro- and nano-scale concave- and convex units, by controlling the propagation behavior of light, form a first pattern 11 with a specific contour and light-dark distribution on a receiving plane (such as a wall or observation screen) away from the metal surface. The visible structure can be prepared on the surface of the metal ornament's body 10 using at least one of the following processes: screen printing, pad printing, relief engraving, laser marking, or inlay, forming a second pattern 12 with a specific shape and visible to the naked eye. The second pattern 12 is then formed on the receiving plane through optical effects. The formation of the first pattern 11 and the second pattern 12 can be achieved through the synergistic effect of one or more optical effects, such as directional reflection, diffraction, interference, and scattering and diffuse reflection.

[0025] Understandably, the surface of metal jewelry can be treated to achieve a surface roughness within a predetermined range to meet the conditions for optical effects to occur. For example, the surface of metal jewelry can be polished to achieve a surface roughness of less than or equal to 0.1 micrometers, creating a smooth mirror-like area that produces strong specular reflection under incident light, projecting a bright outline.

[0026] When the first optical microstructure is illuminated by incident light, its micro- and nano-convex / concave units generate specific optical effects by modulating the light. The protruding parts, through their smooth surfaces, can directionally reflect or phase-modulate the light, causing it to concentrate and form a light spot on the receiving plane. The concave parts, due to their different shapes and depths, cause the light propagation path to be shifted or diffused, thus forming a patterned area on the receiving plane. Through this contrast of light and dark, the first optical microstructure can present a clear first pattern 11 on the receiving plane (such as a wall).

[0027] Furthermore, the visible structure has a lower surface roughness than the first optical microstructure, enabling it to form a second pattern 12 with higher brightness and clearer outline on the receiving plane. During the polishing process of the first optical microstructure, the polishing depth must be controlled to be less than the depth of the micro / nano-level concave-convex units to maintain the integrity and optical function of the first optical microstructure. The synergistic imaging of the visible structure and the first optical microstructure not only enhances the three-dimensionality and gloss of the jewelry but also produces rich visual layers.

[0028] In the first embodiment, the outline of the first optical microstructure is set within the outline of the visible structure, and the first pattern 11 and the second pattern 12 overlap to form a third pattern 13. The outline of the first optical microstructure is completely located within the outline of the visible structure, or the first optical microstructure is completely set on the surface of the visible structure. When illuminated by incident light, the visible structure can form a complete second pattern 12 on the receiving plane. Simultaneously, the first optical microstructure on its surface, by controlling local light, selectively blocks or weakens a portion of the second pattern 12, forming a shadow or dark area with the shape of the first pattern 11. The superposition of these two optical effects ultimately projects a composite third pattern 13 onto the receiving plane. The metal ornament in this embodiment can simultaneously possess high-precision details of the microstructure and clear outlines of the macrostructure, presenting a unique sense of visual depth and layering, significantly enhancing the artistic expression and anti-counterfeiting characteristics of the ornament.

[0029] For example, refer to Figure 1 The visible structure is a raised, engraved five-pointed star, which can form a clear five-pointed star-shaped light spot on the receiving plane (i.e., the second pattern 12). The first optical microstructure is set in the shape of the letter "A" (i.e., the first pattern 11), which is invisible to the naked eye. When a beam of parallel incident light shines on the surface of the metal ornament, the overall outline of the five-pointed star acts as a reflective surface, directing most of the light to the receiving plane, forming a complete five-pointed star bright spot (the second pattern 12). The "A"-shaped first optical microstructure located on the surface of the five-pointed star modulates the local light that shines on it, making it form an "A"-shaped shadow area, i.e., the first pattern 11. Figure 1 (Represented by dashed lines). The bright outline of the five-pointed star and the dark shadow of the letter "A" inside overlap to form a five-pointed star with the shadow of the letter "A" embedded inside, namely the third pattern 13.

[0030] In the second embodiment, the first optical microstructure and the visible structure are at least partially overlapped, and the first pattern 11 and the second pattern 12 are superimposed to form the fourth pattern 14. A portion of the first optical microstructure is disposed on the surface of the body 10 of the metal ornament, and a portion of the structure overlaps with the visible structure. When incident light shines, the first optical microstructure modulates the incident light through micro-nano concave-convex units, forming the first pattern 11 on the receiving plane through light-dark contrast. Simultaneously, the visible structure and the first optical microstructure physically overlap, and the shadows or dark areas formed by the first pattern 11 with specific shapes obscure or weaken a portion of the second pattern 12, thereby creating bright light spots on the receiving plane that are not obscured by the second pattern 12. These bright light spots merge with the dark areas of the first pattern 11 to generate the fourth pattern 14. This embodiment is designed based on the composite optical effect of light and shadow interlacing and lines interweaving, which can present a visual performance with a sense of depth interference and dynamic change characteristics.

[0031] For example, refer to Figure 2 The visible structure is a raised, engraved ring (second pattern 11), and the first optical microstructure consists of four invisible ring structures that partially overlap with the visible structure. When a beam of parallel incident light shines on the surface of the metal ornament, the visible structure should form a complete ring-shaped light spot on the receiving plane. However, at the same time, the four ring structures of the first optical microstructure scatter or diffract the incident light to other directions, forming four dark rings on the receiving plane, namely the first pattern 11. Figure 2 (Represented by dashed lines in the image). Therefore, the circular light spot (second pattern 12) formed by the visible structure and the four dark-colored rings (first pattern 11) formed by the first optical microstructure overlap and superimpose on the receiving plane to display a five-ring pattern.

[0032] In the third embodiment, the first optical microstructure and the visible structure are arranged adjacent to each other, and the first pattern 11 and the second pattern 12 are combined to form the fifth pattern 15. The first optical microstructure and the visible structure are arranged adjacent to each other on the surface of the metal body 10, and they do not overlap in space, but are adjacent to each other. When incident light shines on them, the first optical microstructure forms the first pattern 11 on the receiving plane. The visible structure forms the second pattern 12 on the receiving plane. The first pattern 11 and the second pattern 12 are adjacent to each other on the projection plane, together constituting the fifth pattern 15.

[0033] For example, refer to Figure 3 The visible structure is a raised, etched outline of the letter "S," with a first optical microstructure positioned on either side of the "S"-shaped outline. When light shines on it, the visible structure forms an "S" shape on the receiving plane, i.e., the second pattern 12. The first optical microstructure forms a first pattern 11 on the receiving plane. Figure 3 (Represented by dashed lines). The second pattern 12 and the first pattern 11 form an alternating light and dark "8" shape outline, which is the fifth pattern 15. The shape of the pattern changes as the observer's understanding progresses, and the cognitive transformation from "S" to "8" brings a unique visual interactive experience and fun.

[0034] Furthermore, a second optical microstructure is provided on the surface of the metal ornament's body 10. At least a portion of the second optical microstructure forms a dynamic color pattern 16 through optical effects under incident light. The second optical microstructure can be formed by die stamping or laser engraving on the surface of the metal ornament's body 10, and is invisible to the naked eye. Under incident light, the second optical microstructure can form a dynamic color pattern 16 on the receiving plane through optical effects, achieving a visual effect from static monochrome to dynamic color, further enhancing the uniqueness and attractiveness of the metal ornament.

[0035] Optionally, the second optical microstructure can be a micro / nano grating structure. When illuminated by white light, the grating disperses light of different wavelengths into different directions through diffraction, and as the observer moves, a rainbow-like effect of alternating red, green, and blue colors can be observed. For example, by surrounding the pentagram in the first embodiment with this grating, a dynamically changing colored halo can be added outside the pentagram on the receiving plane, making the overall optical effect more complex and unique.

[0036] Furthermore, the second optical microstructure can also be at least one of a photonic crystal structure, a microlens array structure, or a blazed grating structure. These structures, when illuminated by white light, can all produce dynamic color patterns 16 that vary with the viewing angle through optical diffraction or interference effects, thereby further enriching the optical expressiveness of the metal ornaments.

[0037] Based on the first to third embodiments described above, the second optical microstructure can be arranged around the first optical microstructure and / or the visible structure, and the dynamic color pattern 16 forms a colored border or halo effect around the first pattern 11 and / or the second pattern 12. When incident light shines on it, the second optical microstructure can generate a dynamic color pattern 16 on the receiving plane that changes with the viewing angle. The dynamic color pattern 16 is spatially distributed around the first pattern 11 formed by the first optical microstructure and / or the second pattern 12 formed by the visible structure on the receiving plane, presenting a surrounding colored border or halo effect, thereby significantly enhancing the visual appeal and three-dimensionality of the central pattern.

[0038] For example, based on the five-ring pattern in the second embodiment described above, the second optical microstructure can be arranged around the visible structure and the first optical microstructure. When incident light shines on the surface of the metal ornament, a bright and dark five-ring pattern appears on the receiving plane, and the pattern is surrounded by a colored halo or border, greatly enhancing its visual appeal.

[0039] Based on the first to third embodiments described above, the second optical microstructure may at least partially overlap with the first optical microstructure and / or the visible structure. The dynamic color pattern 16 is superimposed on the first pattern 11 and / or the second pattern 12 to form a first pattern 11 and / or a second pattern 12 with dynamic color changes. The second optical microstructure is at least partially overlapped with the first optical microstructure and / or the visible structure. When incident light illuminates the surface, the second optical microstructure generates a dynamic color pattern 16 that changes with the viewing angle on the receiving plane, while the first optical microstructure and the visible structure respectively form the first pattern 11 and the second pattern 12 on the receiving plane. Due to the structural overlap, the dynamic color pattern 16 and the first pattern 11 and / or the second pattern 12 are correspondingly superimposed on the projection plane to form a first pattern 11 and / or a second pattern 12 with dynamic color changes.

[0040] For example, based on the five-pointed star pattern in the first embodiment described above, a second optical microstructure can be disposed around the first optical microstructure on the surface of the visible structure. When incident light shines on it, the five-pointed star area on the receiving plane can produce a dynamic color effect, while the internal "A"-shaped dark area remains visible. This embodiment can directly impart dynamic color to the main body of the pattern, achieving "body 10 color change," significantly enhancing the visual effect of the metal ornament.

[0041] In the fourth embodiment, a second optical microstructure is disposed between the first optical microstructure and the visible structure, and a dynamic color pattern 16 is located between the first pattern 11 and the second pattern 12, forming a connecting region with a color transition effect. The second optical microstructure is disposed in the region between the first optical microstructure and the visible structure. When incident light shines, the first optical microstructure forms the first pattern 11 on one side of the receiving plane, the visible structure forms the second pattern 12 on the other side of the receiving plane, and the second optical microstructure located between the two generates a dynamic color pattern 16 on the receiving plane. This dynamic color pattern 16 is located in the spatial position between the first pattern 11 and the second pattern 12, thereby forming a visual connecting region with color gradient and dynamic change effects between the two relatively independent patterns.

[0042] For example, refer to Figure 4 The visible structure is a large, raised square, i.e., the second pattern 12. A first optical microstructure is located on one side of the visible structure, and its shape is a small square proportional to the visible structure. When incident light shines, the visible structure forms a bright, large square light spot on the receiving plane, i.e., the second pattern 12, while the first optical microstructure forms a dark, small square on the receiving plane, i.e., the first pattern 11. Figure 4 (Represented by dashed lines). The second optical microstructure is precisely fabricated within the gap between the visible structure and the first optical microstructure, and extends and connects the corresponding adjacent sides of the large and small squares. The second optical microstructure generates a dynamic color pattern 16 on the receiving plane that varies with the viewing angle. Figure 4 (Represented by multiple dashed lines), it presents a visual size gradient effect from dark small squares to bright large squares, realizing a complex dynamic optical effect from a static surface.

[0043] Furthermore, in all the above embodiments, the surface of the body 10 can be any one of a plane, an arc surface, a polygonal surface, or a wavy surface. For example, when the surface of the body 10 is a polygonal surface, the first optical microstructure and the second optical microstructure can be set on different facets, and through the spatial angle between different facets, the first pattern 11 and the dynamic color pattern 16 intersect, overlap, or separate at a specific angle on the receiving plane, forming a complex optical performance with a sense of space and interactive effects. In addition, the body 10 of the metal ornament can also be set to the same shape as the outline of the first pattern 11, the second pattern 12, the third pattern 13, the fourth pattern 14, or the fifth pattern 15, increasing its interest and aesthetics. The various shapes of the body 10 and its surface of the metal ornament not only enrich the ways of presenting optical effects, but also adapt to different wearing scenarios and consumers' personalized needs, broadening the product's application range over time. The metal ornaments in this application can be widely used in jewelry products such as necklaces, rings, and bracelets, and can also be used in the field of collectibles such as medals and commemorative coins, enhancing the added value and artistic beauty of the products through their unique optical effects.

[0044] It should be noted that, for ease of understanding, the specific application structures listed in the above embodiments are all relatively simple. However, in practical applications, the first pattern 11 and the second pattern 12 can also be set as various complex patterns, such as trees, animals, flowers, silhouettes of people, mythological totems, architectural outlines, calligraphic strokes, etc., to reflect the aesthetics and practicality of the metal ornaments. Furthermore, all the above embodiments can be combined to achieve richer and more diverse artistic expression, and to make the metal ornaments have complex visual effects while also possessing extremely high anti-counterfeiting security.

[0045] This application achieves a multi-layered combination of macroscopic and microscopic optical patterns through the coordination of a first optical microstructure, a second optical microstructure, and a visible structure, significantly enhancing the visual artistic effect and interactive appeal of the jewelry. This structure can present a dynamic and static visual fusion under different lighting conditions, while the high-precision processing characteristics of the micro-nano raised and recessed units effectively improve anti-counterfeiting performance. Furthermore, the surface of the metal jewelry can accommodate various shapes, expanding design freedom and application scenarios, and enhancing the product's technological content and aesthetics.

[0046] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
