Abstract

PURPOSE:To emanate a high chroma color by adjusting a beam to reflect from a surface, transmitting the internal part of a substance and injecting the colored beam with a priority to an external part. CONSTITUTION:A colored decoration 1 formed in a jewel shape has a surface 2 exposed to a surface and a surface (pedestal side) 3 not exposed to the surface, a surface side is covered with a reflection preventing coating layer 4 and a mirror surface 5 to reflect the light is provided on a rear surface side. The internal part of the decoration 1 is an artificially formed transparent substance 6 such as synthetic resin, glass and artificial jewels. The color of the transmission beam of a light transmission body 6 has a hue H, a reflection preventing film 4 reflects the remaining reflection beam having a hue (h), and the hue H and the hue (h) are provided so as to be the same or approximate. Thus, the beautiful color beam to exceed the jewel manufactured from a natural raw material is injected while it is an artificially constituted jewel-shaped colored decoration.

Description

[Detailed description of the invention]

The present invention is an artificially constructed jewel-shaped colored ornament,
Beautiful colored rays that surpass those of jewels made from natural materials are emitted.

[Prior art]

Natural gemstone materials are expensive, but even if they could be obtained in large quantities at low cost, the color of gemstones is due to the absorption of a portion of the light rays when they pass through the interior of the gemstone. However, other than that, it is not absorbed from the surface of the gemstone (
(4 colors not reflected) white light rays are reflected. There is no problem with white gemstones like diamonds, but problems arise with colored gemstones like rubies. That is, the light rays transmitted through the inside of the gemstone and emitted appear to shine as colored bright spots, and the light rays reflected from the surface appear to shine as white bright spots. This current dispute is particularly noticeable when the chroma of a gemstone is high and the lightness is low (dark).For example, in the case of deep red, the lightness is about 3.5 in the Munsell color system, and the amount of light does not fall to 10% culm, and it becomes white. The beautiful colors are disrupted by the light reflected from the surface. The presence of such interfering light rays due to surface reflected light (white light) has been thought to be an unavoidable phenomenon for colored gemstones processed from natural materials. Colored rays and white rays on gemstones
Up until now, people have not thought it strange that there is a seed ray and both of them shine brightly together.

[Issue to be solved]

In the field of "gems," those made from natural materials were considered high-class, while those artificially imitated were considered low-class. If it were possible to artificially create colors that were more beautiful than those produced from natural materials, people might prefer the artificial island.

[Means to solve the problem]

Going against the old wisdom that jewelry is meant to sparkle and sparkle, by adjusting the light rays reflected from the surface, we prioritize colored rays that are less likely to penetrate the interior of the material and be partially absorbed. By injecting it to the outside,
This makes it possible to emit extremely pure (highly saturated) colors. This is a beautiful ``artificial'' ray of light that humanity has never encountered before. The present invention is configured as follows. In other words, an artificial colored transparent material with a shape similar to a jewel is formed with a reflective mirror surface on the surface that is not exposed to the surface (the pedestal side), and an anti-reflection film is formed on the surface that is exposed to the surface. The color of the transmitted light beam has a hue H, and the antireflection film reflects the residual reflected light beam having a tint, and is provided so that the hue H and the hue are the same or similar.

[Example 1] In Figures 1 and 2, 1 is a jewel-shaped decoration, 2 is a surface exposed to the surface, 3 is a surface not exposed to the surface (pedestal side), and 0 surface side is reflective. The layer 4 covered with the protective coating layer 4 is a thin film, for example, one quarter of the wavelength of light, and the thickness is exaggerated in the figure. A mirror surface 5 that reflects light is provided on the back side. The bi-plane structure is formed by any known method, such as metal vapor deposition, sputtering, amalgam, or the like. The interior 6 of the decorative body 1 is an artificially made transparent body such as synthetic resin, glass, or artificial jewelry. The means for coloring the transparent body may be such that the entire transparent body is colored, or only a part of the transparent body may be colored. For example, when the upper surface of 6 (membrane 4 side) is colored and transparent,
For example, if the lower surface of 6 (mirror surface 5 side) is colored and transparent, for example, a colored body can be placed inside 6 like a sandwich filter).
Even if a colored portion is provided anywhere on the transparent body 6, it will be visible because the transparent body 6 is transparent, and as a result, the entire transparent body 6 will be seen as a colored object. Since such an artificial transparent body cannot have a high refractive index like diamond, it cannot rely solely on total internal reflection, and the amount of reflected light is increased by the reflecting mirror 5. The amount of colored light rays (hereinafter referred to as colored rays) that pass through a transparent object and emerge onto the surface increases due to the reflective mirror, and overcomes the white light rays reflected from the two surfaces, maintaining the beauty of the colors. can. At the current state of the art, anti-reflection coatings cannot prevent 100% of light rays from being reflected, and some light rays are reflected without being prevented from being reflected. Generally, when designing an antireflection film, an arbitrary wavelength λ is selected from among the target light beams as a reference light beam, and the film is designed to produce the best antireflection effect for that wavelength formula. Therefore, at wavelengths far from the wavelength λ, reflected rays remain on the surface (hereinafter referred to as residual reflected rays). The present invention utilizes residual reflected light of wavelengths that cannot be prevented from being reflected, contrary to general antireflection films. For example, if the hue (hue) H of the light beam transmitted through the transparent body is deep red (near the wavelength 620 nm) as shown in Figure 7, the anti-reflection film will prevent the reflection of the blue light and the residual reflected light It.
Design so that ilh appears in red. When the transmitted light is blue (for example, around a wavelength of 470 nn), the design is such that red light is prevented from being reflected and residual reflection appears in blue, as shown in FIG. The transmitted light is reddish-purple (e.g. wavelength 47
In the case of a mixture of wavelengths of 0 nm and 620 nm, the design is such that the green light is prevented from being reflected and the remaining reflected light appears reddish-purple as shown in FIG. 5 Anti-reflection involves complex elements such as when the anti-reflection film is multi-layered, so it may not be as simple as shown in Figures 7 to 9, but the residual reflected light will always have a color and the hue will change. The hue is designed to be close to the hue H of the transmitted light. There is no problem if H and h completely match, but even if they do not match, an approximation suffices. In this case, approximations include, for example, deep red (λ620nm), orange (590n+*), dark blue (includes 470nm), blue-green (490nm), reddish-purple (λ6
This is a case where the wavelengths are similar, such as 20 nm and 470 r+m) and deep blue (470 nm). With such similar hues, it is possible to significantly reduce the unpleasant reflection of white light that affects human perception, compared to conventional jewel-like decorations such as natural material processed products. In addition, if you sacrifice the effect (aesthetic sense), you can use hues that are farther away from H and H than the above values, such as blue and green, red and yellow, magenta and red, magenta and blue, etc. It is acceptable to choose colors that are close to each other on the chromaticity diagram of the CIE color system. Generally speaking, an anti-reflection film is something that prevents the reflection of specific wavelengths (for example, visible light), but it may not be called an "anti-reflection film" when light rays that are not prevented from being reflected are used, as in the present invention. . However, even in such a case, it must prevent unnecessary reflection of light, so it is expressed as an anti-reflection film in the present invention. In the present invention, in order to prevent the reflection of "white light rays", the reflection of light rays having wavelengths that are complementary to one hue H is prevented. However, the negative expression of the word 'prevention' may lead to misunderstanding, so I will provide an additional explanation. It is necessary to prevent reflection of incident visible light rays and light rays whose hue is similar to that of the colored transparent material. If there is a "selective reflection film" that can reflect only the rays of hue H among the incident rays at a high rate, it may be tolerant to rays of hues other than Even without antireflection, the hue may be perceived as H.
Even if the description is changed to "selective reflection film," the content remains the same.

[Embodiment 2] In the above embodiment, a reflective mirror 5 was deposited on a transparent body 6. However, as long as the effect is maintained, it is not necessary to optically integrate the transparent body 6 and the reflecting mirror 5 in this way, and the reflecting mirror may be provided as an optically separate body. For example, a support such as a pedestal (not shown) and a back cover may be formed into a reflecting mirror.

[Embodiment 3] It is easy to make the transparent body 6 colored, and there is no reason to avoid it, but one real M! As an i-form. The transparent body may be uncolored or have no color, and the antireflection coating may instead be colored.

[Embodiment 4] As described above, in the present invention, a reflecting mirror is provided on the side that is not exposed to the surface, but if the amount of reflected light is tolerable, the reflecting mirror may be omitted. When a transparent body is made directly or indirectly from a substance, a natural or artificial transparent body with a high refractive index may be used and the reflecting mirror may be omitted. In each of the embodiments, the shape of the exposed side 2 of the light-transmitting body 1 is multifaceted as shown in FIG. 1 and 2, a single surface as shown in FIG. It can be made into any shape suitable for jewelry or ornaments, such as those composed of curved surfaces. The mirror surface provided on the non-exposed side may be multifaceted as shown in FIG. 1, 3, or may be a single mirror-shaped mirror surface as shown in FIG. 5, 3, or may be a curved surface as shown in FIG. 6, 3. It is often made into an arbitrary reflective surface shape, such as a surface with many irregularities. Further, throughout each embodiment, in order to prevent the anti-reflective film from being charged with static electricity, it is recommended that the film 4 and a support such as a pedestal (not shown) be electrically connected and grounded. It is advantageous if 4 itself has antistatic properties. In addition to accessories such as pendants, brooches, and rings, they can also be used for items used in other fields, such as toys,
It may also be used as a decorative component to add beauty to stationery, personal items, clothing, etc.
