Description

Technical Field

[0001] This utility model belongs to the field of commemorative medal technology, and in particular relates to a new type of colorful commemorative medal. Background Technology

[0002] Commemorative medals are badges with specific themes and commemorative significance, usually made of metal, alloy, or other materials, used to commemorate important figures, historical events, significant achievements, or special moments. Their designs often incorporate symbolic patterns, text, or dates, carrying cultural and emotional value while serving as symbols of honor, collectibles, or event souvenirs. Commemorative medals are widely used in national celebrations, military honors, sporting events, school anniversaries, and other fields, combining promotional, commemorative, and artistic functions; they are small yet profoundly meaningful.

[0003] In practical use, commemorative badges lack vibrant colors, resulting in a relatively simple visual appeal. Especially in dimly lit environments or with limited display conditions, they can easily appear flat and dull, failing to attract viewers' attention immediately. Furthermore, in the modern design trend that pursues personalization, artistry, and interactive experiences, commemorative badges lacking color variation and gloss may be less aesthetically pleasing and attractive, hindering the enhancement of collectible value and emotional resonance. This shortcoming, especially in the context of fierce competition among similar products, may affect their market performance and dissemination effectiveness, thus hindering user convenience. Therefore, we propose a new type of vibrant commemorative badge. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of colorful commemorative medal to solve the problems mentioned in the background art.

[0005] In view of the above, this utility model provides a novel colorful commemorative medal, comprising: A base, the top of which is fixedly connected to a circular plate, and the top of which is fixedly connected to the main body of the commemorative medal, the main body of the commemorative medal being located inside the circular plate; The top plate is fixedly connected to the top of the annular plate, and a microprism structure layer is provided at the bottom of the top plate, and an optical film layer is provided at the bottom of the microprism structure layer.

[0006] In this technical solution, when external natural light or artificial light shines on the commemorative medal, the light first penetrates the top acrylic glass plate. Due to the good light transmittance of acrylic glass, the light enters the microprism structure layer below without significant attenuation. The microprism structure layer is made of polycarbonate. The bottom of the microprism structure layer is processed with a dense array of microprisms. The microscopic triangular prism structure on its surface will refract and disperse the incident white light. Due to the difference in refractive index, light of different wavelengths (colors) is deflected to different degrees when passing through the microprisms, initially decomposing the mixed white light into monochromatic lights such as red, orange, yellow, green, blue, indigo, and violet, forming a basic color separation effect.

[0007] After being dispersed by the microprism structure layer, the monochromatic light continues to propagate downwards, passing through the optical adhesive between the microprism structure layer and the optical film layer, and reaching the optical film layer. The optical film layer is made of a diffraction grating film. The periodic micro-nano etched structure on the surface of the diffraction grating film will diffract monochromatic light of different wavelengths a second time. According to the grating equation (diffraction angle is positively correlated with wavelength), the monochromatic light is further separated in wavelength order and deflected to different angles, significantly enhancing the contrast and sense of layering of color separation. At the same time, the main body of the commemorative medal is located at the top of the base. The aluminum metal layer on its surface has high reflectivity, which will reflect the light that is not fully transmitted back to the microprism structure layer and the optical film layer, forming a cycle of multiple reflection-dispersion-diffraction. Through the above structure, the surface of the main body of the commemorative medal can present a dynamic flowing color effect that changes with the viewing angle, combining optical aesthetics and structural stability, thus making it convenient for users.

[0008] In the above technical solution, the material of the microprism structure layer is polycarbonate, and a microprism array is formed at the bottom of the microprism structure layer.

[0009] In this technical solution, the material of the microprism structure layer is polycarbonate. The bottom of the microprism structure layer is processed with a dense array of microprisms. The microscopic triangular prism structure on its surface will refract and disperse the incident white light. Due to the difference in refractive index, light of different wavelengths will be deflected to different degrees when passing through the microprisms, initially decomposing the mixed white light into monochromatic light such as red, orange, yellow, green, blue, indigo, and violet, forming a basic color separation effect.

[0010] In the above technical solution, the top plate is further made of plexiglass.

[0011] In this technical solution, a top plate is provided, which is made of plexiglass. Because plexiglass has good light transmittance, light enters the microprism structure layer below without significant attenuation.

[0012] In the above technical solution, the optical film layer is further described as a diffraction grating film.

[0013] In this technical solution, an optical film layer is set, the material of which is a diffraction grating film. The periodic micro-nano scribed structure on the surface of the diffraction grating film will diffract monochromatic light of different wavelengths twice. According to the grating equation, the diffraction angle is positively correlated with the wavelength, which further separates the monochromatic light in wavelength order and deflects it to different angles, significantly enhancing the contrast and sense of layering of color separation.

[0014] Furthermore, in the above technical solution, the main body of the commemorative medal is made of vacuum-plated aluminum.

[0015] In this technical solution, the main body of the commemorative medal is made of vacuum-plated aluminum, which has a high reflectivity. This reflects light that is not fully transmitted back to the microprism structure layer and the optical film layer, forming a cycle of multiple reflections, dispersions, and diffractions.

[0016] In the above technical solution, further, the plane of the microprism structure layer is close to the top plate, and the plane of the microprism structure layer with the microprism array is close to the optical film layer.

[0017] In this technical solution, the refraction effect can be improved by bringing the plane of the microprism structure layer close to the top plate, and by bringing the plane of the microprism structure layer with the microprism array close to the optical film layer.

[0018] In the above technical solution, the top plate and the microprism structure layer are further bonded together by optical adhesive, and the microprism structure layer and the optical film layer are bonded together by optical adhesive.

[0019] In this technical solution, the top plate, the microprism structure layer and the optical film layer can be fixedly connected by the optical adhesive.

[0020] The beneficial effects of this utility model are: When natural light or artificial light shines on the medal, the light first penetrates the top acrylic glass panel. Due to the excellent light transmittance of acrylic glass, the light enters the microprism structure layer below without significant attenuation. The microprism structure layer is made of polycarbonate, and a dense array of microprisms is processed at the bottom of the microprism structure layer. The microscopic triangular prism structure on its surface will refract and disperse the incident white light. Due to the difference in refractive index, light of different wavelengths (colors) is deflected to different degrees when passing through the microprisms, initially decomposing the mixed white light into monochromatic lights such as red, orange, yellow, green, blue, indigo, and violet, forming a basic color separation effect.

[0021] After being dispersed by the microprism structure layer, the monochromatic light continues to propagate downwards, passing through the optical adhesive between the microprism structure layer and the optical film layer, and reaching the optical film layer. The optical film layer is made of a diffraction grating film. The periodic micro-nano etched structure on the surface of the diffraction grating film will diffract monochromatic light of different wavelengths a second time. According to the grating equation (diffraction angle is positively correlated with wavelength), the monochromatic light is further separated in wavelength order and deflected to different angles, significantly enhancing the contrast and sense of layering of color separation. At the same time, the main body of the commemorative medal is located at the top of the base. The aluminum metal layer on its surface has high reflectivity, which will reflect the light that is not fully transmitted back to the microprism structure layer and the optical film layer, forming a cycle of multiple reflection-dispersion-diffraction. Through the above structure, the surface of the main body of the commemorative medal can present a dynamic flowing color effect that changes with the viewing angle, combining optical aesthetics and structural stability, thus making it convenient for users.
