Abstract

PROBLEM TO BE SOLVED: To provide an optical decoration body that artificially creates brightness existing in the nature such as twinkles of stars and diamond dust.SOLUTION: The optical decoration body 10 includes: a shading layer 12 of a light blocking property; a translucent layer 14 of light transmissivity; and a reflective layer located between the shading layer 12 and the translucent layer 14. The viewer appreciates the light reflected by multiple reflectors 24 provided on the reflective layer 14. The translucent layer 14 is treated as to reduce the light transmissivity and allows only the light of high brightness of the reflected lights to go through the translucent layer 14, while the other lights of low brightness do not go through or even if they go through, the light amount is extremely small. Thus the viewer sees something like lights of high brightness dotting through the translucent layer 14 and has an impression as if twinkles of stars and dimond dust are seen in front of him/her.SELECTED DRAWING: Figure 4

Description

The present invention relates to a light decorative body that artificially creates a natural sparkle such as star glitter or diamond dust.

Conventionally, a decorative body that expresses decorativeness using light is widely known. For example, the decorative body described in Patent Document 1 includes a transparent single-phase organic glass and closed cells present in the glass. Each closed cell does not overlap with each other in the thickness direction, and is dispersed in a plane and randomly along a two-dimensional plane in the plane direction. When illumination light such as LED light is irradiated on the end surface from the end surface side of the decorative body, the irradiation light is bent at the concave surface of the organic plate glass formed on the outer surface of the closed cell that was received first, and the presence of the closed cell was enhanced. There is a feature in the point. In addition, the decorative body described in Patent Document 2 includes a surface plate made of a light-transmitting material having a concavo-convex motif formed on the surface, and a colored light-transmitting material located inside the surface plate. The ornamental ornamental body composed of the colored plate made of is characterized in that a large number of bubbles are formed inside the front plate. When natural light or artificial light hits the decorative body, the light hits a large number of bubbles and is reflected and refracted, and subtle differences in reflection and refraction occur due to differences in the irregularities on the surface of the bubbles. It is characterized in that it changes the color and shade of the motif when viewed from the plate surface.

The conventional decorative object is for viewing the decorative object from the opposite direction of the light irradiation direction, so that not only the light reflected by the bubbles but also the direct light from the light source enters the field of view, and the whole is brightly illuminated. It gives a gorgeous impression. With conventional ornaments, it has been difficult to create vibrant sparkles that appear in the background, such as the glittering stars and diamond dust that exist in nature.

An object of the present invention is to provide a light decorative body that artificially creates a natural shine such as star glitter or diamond dust.

In order to solve the above-described problems, the present invention provides a light decorative body configured as follows.

The light decorative body of the present invention includes a light-shielding layer having a light-shielding property, a light-transmitting light-transmitting layer, and a reflective layer that reflects light irradiated between the light-shielding layer and the light-transmitting layer, The translucent layer has a translucency that allows the reflected light reflected by the reflective layer to selectively pass therethrough.

The light shielding layer has a function of making reflected light stand out by blocking light incident from the back surface. The light-transmitting layer has a function of allowing light with a clear outline to be visually recognized by transmitting light with relatively high luminance and transmitting light with low luminance other than that as much as possible.

The light decorative body can be configured such that the reflective layer encloses bubbles and reflects light at the outline of the bubbles. In this case, it is desirable that the translucent layer has a translucency that does not transmit the reflected light at the outline of the bubble. In addition, the reflective layer can be constituted by a plurality of bubble layers containing bubbles, and further can be constituted by a bubble layer containing bubbles and a non-bubble layer not containing bubbles.

Moreover, a light decoration body can be set as the structure provided with the reflector in which a reflection layer has a reflective surface. In this case, it is desirable that the translucent layer has a translucency that does not transmit the reflected light at the contour of the reflector. Further, the reflector may be embedded with only a part thereof exposed or may be a spherical body. Further, it may be fixed to the light shielding layer via a relatively low reflection rod-shaped body.

Further, it is desirable that the light decorative body is shielded so that light irradiated between the light shielding layer and the light transmitting layer does not pass through between the two layers.

According to the light decorative body of the present invention, direct light is blocked so that only relatively bright light among the reflected light can be visually recognized. It is possible to create a radiance that exists in the natural world. As a result, it is possible to obtain a soothing and healing effect that cannot be obtained with a conventional light decorative body.

Embodiments of the present invention will be described with reference to the drawings. First, the basic configuration and operation of the light decorative body will be described with reference to FIG. The light decoration body 10 is constituted by three layers including a light shielding layer 12, a light transmissive layer 14, and a reflective layer 16. The light blocking layer 12 is a layer for blocking the transmission of light from the back of the light decorative body 10, that is, the direction opposite to the viewing direction of the light decorative body 10. Although it is desirable to have a complete light-shielding property that does not transmit all light, light transmission that does not impair appreciation is acceptable. As the material of the light shielding layer 12, a veneer plate, a metal plate, a colored resin, or the like can be used, or a transparent resin or glass obtained by performing a coloring treatment with a dark pigment on a resin or glass can be used. The light transmissive layer 14 is a layer that transmits light for viewing. In order to reduce the light transmittance, it is colored with a dark pigment that easily absorbs light, etc., so that only the reflected light with relatively high brightness is selectively transmitted, and other light is blocked as much as possible. Is done. Note that the transmittance can be reduced by a method other than using a pigment. For example, a colored film or a polarizing film may be affixed or surface processing such as sanding the surface of the layer may be performed.

Next, the configuration and operation of the reflective layer 16 will be described. The reflective layer 16 is located between the light shielding layer 12 and the light transmissive layer 14 and has a function of reflecting light irradiated between the light shielding layer 12 and the light transmissive layer 14. The light emitted from the light source 18 is reflected by the reflecting layer 16 and travels in each direction. Of these, the reflected light that has passed through the light transmitting layer 14 becomes an object to be viewed on the light decorative body 10. The light source 18 uses sunlight or artificial light from a lighting fixture. There is no limitation on the type of lighting fixture, but if it is an LED, the light distribution can be easily controlled with high brightness and high directivity.

The reflective layer 16 can be implemented in various forms, but here, two typical forms will be described. In the first embodiment, as shown in FIG. 1, the reflective layer 16 is made of a transparent resin such as a polyester resin, an epoxy resin, or a UV resin, and a plurality of bubbles 20 are formed therein. As shown in FIG. 3, when light is irradiated between the light shielding layer 12 and the light transmissive layer 14, light is reflected at a boundary portion (bubble contour portion) between the bubble 20 and the transparent resin. Of these reflected lights, only the reflected light with particularly high brightness is transmitted through the light transmitting layer 14. The other low-brightness reflected light is absorbed by the light-transmitting layer 14, so that it cannot be transmitted, or even if it is transmitted, the amount of light is very small and hardly noticeable. As a result, only one point of the bubble 20 is shining strongly, and as shown in FIG. 8, it is possible to appreciate the brilliance like a star or diamond dust. In addition to the transparent resin, the reflective layer 16 can also be configured by generating bubbles in a glass containing bubbles or in a water tank filled with water.

The reflective layer 16 can also be composed of a plurality of layers. For example, when the reflective layer is composed of three layers and each encloses the bubbles 20, a greater sense of distance is created between each bubble 20 and the viewer, and thus the light-transmitting layer 14 is obtained. A three-dimensional perspective can be produced by sparkling. In addition, a bubble layer containing bubbles and a non-bubble layer not containing bubbles can be mixed.

The 2nd form of the reflection layer 16 is comprised by the reflector 24 arrange | positioned inside the frame 22, as shown in FIG. The reflector 24 can be arranged at an arbitrary position in the frame, but is fixed to the light shielding layer 12 here. The reflector 24 may be made of any material as long as it has a property of reflecting light, such as a glass piece, a metal piece, or a resin. Further, the light shielding layer 12 having water droplets attached thereto by spraying or the like can be used as the reflector 24.

As shown in FIG. 4, when light is irradiated between the light shielding layer 12 and the light transmitting layer 14, light is reflected on the surface of the reflector 24. Of these reflected lights, only the reflected light with particularly high brightness is transmitted through the light transmitting layer 14. The other low-brightness reflected light is absorbed by the light-transmitting layer 14, so that it cannot be transmitted, or even if it is transmitted, the amount of light is very small and hardly noticeable. As a result, only one point of the reflector 24 is shining strongly, and the brightness such as stars and diamond dust can be appreciated.

Note that the shape and size of the reflector 24 are not limited to a specific form, but it is necessary to consider the shadow generated in the light shielding layer 12 due to the irradiation light from the side. Since the shadow generated in the light shielding layer 12 may be visible depending on the transmittance of the light transmitting layer 14, it is ideal that the shadow is not generated, or even if it is generated, it is desirably small and inconspicuous. Therefore, it is preferable that the reflector 24 is as small as possible and low in height while ensuring an area of a reflecting surface for reflecting a sufficient amount of light.

Although FIG. 2 shows an example in which the reflector 24 is directly installed on the surface of the light shielding layer 12, the reflector 24 can also be installed by other methods. For example, as shown in FIG. 5, the support layer 26 may be installed at the boundary with the light shielding layer 12 so that the reflector 24 is surrounded by the support layer 26. According to this installation method, the height and area of the portion exposed on the surface of the support layer 26 can be freely adjusted, so that it is easy to secure the area of the reflecting surface and adjust the balance of the shadow size. Moreover, according to this installation method, even if it is a spherical thing difficult to fix to the light shielding layer 12, it can install easily. If the support layer 26 is made of a relatively flexible material such as clay, the reflector 24 can be installed by being pushed into the clay. Also, there is a method in which a molten resin or the like is poured into a mold in which the reflectors 24 are appropriately arranged and solidified around the reflectors 24.

In addition, as shown in FIG. 6, for example, there is a method in which the reflector 24 is attached to the tip of an elongated rod-like body such as the pin 28 and the pin 28 is inserted into the light shielding layer 12. In this case, a low-reflective material is used for the pin 28 or a low-reflective coating is applied to suppress reflection. Further, the pin 28 is made as thin and short as possible to suppress the occurrence of shadows. 5 and 6, the reflector 24 is represented as a spherical body. However, the reflector 24 has a function as a reflector as long as it includes a flat surface or a curved surface as at least a part of the reflecting surface. Therefore, even a shape that is not a perfect sphere, for example, a spherical notch (spherical crown) or a pedestal (spherical zone) can be used as the reflector 24.

In the manufacture of the light decorative body 10, the most labor and cost are required for the reflective layer 16, and therefore, when mass production is assumed, how to reduce the man-hours related to the reflective layer 16 becomes a problem. There are various methods for solving this, but the simplest method is to manufacture the light shielding layer 12 and the reflector 24 by integral molding. In the case of integral molding, it can be easily manufactured by pouring a resin or the like into a mold provided with depressions at appropriate intervals. Since the completed integrally molded product serves as the light shielding layer 12 and the reflector 24 as shown in FIG. 7, it is possible to reduce the required man-hours as compared with the case of individually manufacturing and assembling.

If the reflected light is an object of appreciation, it is possible to express a finer and finer glitter than when using direct light as in the past. For example, even very fine bubbles (bubbles having a diameter of about 0.1 mm) can be reflected by accurately reflecting light from the light source. If a similar sparkle is expressed by direct light, for example, when a pinhole is formed in the light shielding layer 12 and direct light that has passed through the pinhole is intended for viewing, a sparkle having a diameter of about 0.1 mm is created. Is extremely difficult. By using the reflected light in this way, a more delicate shine expression can be technically realized and a more realistic expression can be realized. When a water drop is used as a reflector, the permanent time is lost, but the production time is further shortened.

In addition, when using direct light, a plurality of light sources are installed in order to supply light evenly over the entire surface of the decorative body, or the light is diffused by extending the distance between the decorative body and the light source. Will increase the size and production costs. On the other hand, if the reflected light is used, it is possible to express sparkle that can sufficiently withstand viewing by installing at least one light source on the side of the decorative body.

If the outer periphery of the reflective layer 16, that is, between the light shielding layer 12 and the light transmitting layer 14, is shielded, the reflected light can be more clearly appreciated. By shielding this portion, it is possible to prevent light emitted from the light source 18 to the reflective layer 16 from leaking to the outside, and to prevent light other than the light source 18 from entering the reflective layer 16. The extra light will not hinder viewing.
