Description

  The present invention is a method for creating a variety of optical designs by transmitting natural rays or artificial rays to create various optical designs by spectral dispersion, refraction, and lens action, and complexly changing depending on the viewing distance and viewing angle. And the creation substrate.

  In Japan, the economic scale has further expanded through the period of economic growth, and along with this, the standard of living has improved remarkably, and so consumer behavior has become extremely diversified. In other words, starting with eating and eating out in the diet, increased outdoor life by using cars, working housewives with increased leisure time, learning at paintings, music, theater or culture school, and health-oriented background As such, there are a wide variety of consumption behaviors such as increasing use of hot springs, hot bath facilities, or resort facilities.

For this reason, there are a huge number of restaurants in the suburbs, not only in urban areas, but also in the suburbs, hot-bath facilities, health lands, beauty salon facilities, etc. that deal with health orientation, and even leisure facilities and resort facilities. It has come to stand.
In addition, in recent years, since foreign capital and foreign companies have entered the market one after another in anticipation of an increase in consumption behavior, fierce competition has been developed among these companies. Many lost companies have also occurred.

Many of these lost companies are the result of attracting customers with low prices for goods and services they provide, but current consumers and users have sufficient purchasing power. And because it is possible to know information on various goods and services on the background of computerization, the environment and atmosphere to be consumed or used rather than the cheap price and quality, that is, the fun and fun to use, the fun and the comfort. Consumption or use behaviors are being sought in the pursuit of goodness, novelty, wackiness, safety and security, and this is the key to attracting customers and maintaining business.
There are also cases where bold interior and exterior renovations are being made to improve the facility environment, but in addition to the enormous renovation costs, long-term closures are also required, and even if the tentatively innovative interior and exterior are made However, it is merely a change in the structure, and on the other hand, consumption or users are of both young and old, so it is indispensable to create a wide range of consumption or environment and atmosphere that satisfy users.

  Thus, in recent years, attempts have been made to improve the environment and atmosphere by arranging lighting in the facility directly and indirectly, or by using colored light, but the feeling of calmness and softness are weighted. Eventually, it does not lead to improvement of the fixed environment, atmosphere, etc., and requires large electric power in addition to the equipment cost for the lighting device.

In view of this situation, the inventors have conducted extensive research, and as a result, the inventors have made a retroreflective process on one side of a synthetic resin film that has already been developed and put on the market. In addition to the light-reflecting function of the light retroreflective film to ensure the safety of dangerous objects at long distances and thus ensure safety, further research on the light-transmitting function results in a translucent sheet. If light transmission is applied to the creation base material formed by subjecting one side of the entire surface to regular and pyramid-shaped fine and numerous prism processing, spectral dispersion action, refraction action, lens action, and transmission light The present inventors have determined that an optical design pattern that is extremely diverse and multicolored can be created depending on the incident angle and the viewing angle.
Japanese Patent Publication No. 8-11874

  The present invention is arranged at an appropriate position on the outer surface or inner surface of a facility for consumption or use, and directly or indirectly transmits natural light or artificial light to create and change various optical designs. The purpose is to provide a method for creating a variety of optical designs that can improve the environment and atmosphere into a new space full of fun, fun, and excitement, and a creation substrate.

  The technical means adopted by the present invention in order to solve the above-mentioned problems are excellent in the translucency of natural light and artificial light, and deteriorated by light, in particular, long-term light resistance from natural light containing a large amount of ultraviolet rays. In order to form a fine and uniform prism on one side, it is preferable that the one side has a lower hardness than the other side. Different polycarbonate resins and methacrylic resins are co-extruded to form a sheet base material with the integral two-layer structure to a required thickness, and a regular triangular pyramid is formed over the entire low-side surface of the sheet base material. A large number of prisms are pressure-molded in a shape or an isosceles triangular pyramid shape and connected to form a base material for creating various optical designs.

  Furthermore, the creation of various optical designs The substrate is excellent in light transmission and light resistance, and has two layers with different hardnesses. Since it is possible, it is a film material made of nitrocellulose, cellulose triacetate, cellulose tributyrate, polyester, polyamide, or polystyrene film material having excellent translucency and different hardness, other than the integral two-layer structure by coextrusion. Can also be used in which a prism is pressure-molded on the surface of the low hardness laminated film.

  Furthermore, when such a substrate for creating a variety of optical designs is put into practical use, a huge number of fine irregularities are formed on the prism surface to prevent light transmission from being hindered by dust adhering to long-term use. Therefore, the protective layer is made of an ultrathin film made of a material that forms the creation base material, and the prism layer is laminated with a protective layer.

Creation of various optical designs created using such a substrate The method of creating a variety of optical designs using a base material is directly irradiated or indirectly irradiated with natural light such as facilities used by consumers or users. In addition, by stretching or sticking to a place where light is transmitted, a six-radial spectrum pattern is created which is spectrally dispersed by direct incident light transmission of natural light, and depending on the incident angle depending on indirect incident light transmission Refracted light creates irregular spectral spots everywhere.
In addition, creating a variety of optical designs If a substrate is stretched or pasted over a wide area, the six radial spectral patterns will be created over the entire surface, and the spectral patterns may be deformed and lost depending on the viewing angle. Furthermore, if the base material for creating a variety of optical designs is divided and stretched or stuck, six radial spectral patterns or irregular spectral spots are created.

  Furthermore, in the case of artificial light, it is arranged as a shade, cover, or cover that transmits the light emitted from the light source, that is, the illuminator, so that if the emitted light approximates white light, it is a spectrally dispersed six-radial pattern. Spectral patterns are created, and the irregular spectral spots are created everywhere by irradiating the white light indirectly, and the spectral spots are variously changed depending on the viewing angle. Is issued.

  As described above, the present invention uses a sheet base material having a two-layer structure by co-extrusion using synthetic resin materials having excellent translucency and different hardness as described above or a laminated structure of sheet materials made of the respective synthetic resin materials. In addition, when a large number of prisms with a regular triangular pyramid shape or an isosceles triangular pyramid shape are uniformly pressure-formed on the entire low-side surface, highly accurate pressure forming can be achieved efficiently and homogeneously. Because the creation base material with high-precision prisms is formed, natural and artificial rays that are transmitted through the incident light are satisfactorily spectrally dispersed and refracted, creating clear and diverse optical design patterns. Will be.

In addition, since different synthetic resin materials are used for the creation base material, mutual complementation can be achieved by a synthetic resin material that also selects weather resistance, light resistance, heat resistance, tensile strength, bending strength, and the like required for practical use.
Furthermore, various optical design creation methods of the present invention can be applied to natural light directly or indirectly by extending or pasting a large area or a small area on a lighting ceiling, exterior wall, window or door of a facility, etc. It can be implemented by transmitting light incident on or transmitting white light of artificial light directly or indirectly, so there is not only the burden of installation cost and the cost of installing a new power supply device and light source, but also the burden of power cost. It becomes useless.
In the case where the protective layer is formed on the prism surface of the substrate of the present invention, the protective layer surface is smooth even if dust or the like is adhered due to long-term use, so that cleaning and removal can be easily performed.

  A coextruded polycarbonate resin and methacrylic resin are used to form a monolithic pyramid shape or isosceles triangular pyramid shape on the entire low-side surface of a sheet base material that has been integrally extruded with a thickness of 0.5 mm. These prisms are pressure-molded to form a creation base material, and are directly stretched over the daylighting ceiling of an all-weather leisure facility with a required area or attached to the inner surface of a glass roof.

An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1A is an explanatory view of a sheet base material 1A by coextrusion molding for forming the base material 1 for creating various optical designs of the present invention. Of course, the sheet base material 1A has not only excellent translucency, but also toughness such as weather resistance, light resistance, heat resistance, tensile strength and bending strength that can be adapted for long-term use. One of the side surfaces is desired to have low hardness in the pressure molding.
Synthetic resin materials having excellent translucency here include polyester resin, polyamide resin, polystyrene resin, polyvinyl chloride resin, nitrocellulose resin, cellulose triacetate resin or cellulose trioxide resin in addition to polycarbonate resin and methacrylic resin. Butyrate resins and the like can be mentioned, but in order to cope with the performance in practical use, it is advantageous to effectively complement and combine the performance of each synthetic resin material.

  In addition, it is important that a synthetic resin material selected from these materials be molded into an integral two-layer structure by coextrusion molding in order not to impede translucency and to exhibit uniform physical performance. However, in co-extrusion of such synthetic resins, the compatibility of the synthetic resin materials is indispensable. For this reason, in the present invention, a sheet base material 1A coextruded with a polycarbonate resin and a methacrylic resin is selected as one of them. Of course, in addition to the synthetic resin material, it can be adopted if co-extrusion molding is possible depending on mutual compatibility and molding conditions.

  On the other hand, nitrocellulose resin, cellulose triacetate resin, or cellulose tributyrate resin, etc., which are excellent in translucency, are difficult to co-extrusion molding. In addition, it is possible to use a sheet substrate 1B obtained by laminating a light-transmitting film material 11B having a low hardness and an integral two-layer structure using a light-transmitting binder 11C. The thickness of the sheet base material 1A or the sheet base material 1B varies depending on the purpose of use, but is approximately 0.3 to 1.0 mm.

As shown in FIG. 2, the sheet base material 1A thus formed in an integral two-layer structure has a fine and enormous number of prisms 1C in the shape of an equilateral triangular pyramid or isosceles triangular pyramid over the entire low-side surface 11A. Are uniformly and uniformly formed by pressure molding.
The size of the prism 1C depends on the thickness of the sheet substrate 1A or the sheet substrate 1B, but in the present invention, a prism of approximately 0.3 to 1.0 mm is used. Alternatively, in the case of an isosceles triangular pyramid, the length of the bottom three sides is about 160 to 450 μm, and the length of the three sides from the bottom to the top is about 170 to 400 μm. In the regular triangular pyramid shape, the apex angle from the top to the bottom three sides of the prism 1C involved in the spectral dispersion and refraction of light rays upon the transmission of natural rays or artificial rays is formed at 60 degrees. Also in the shape, it is desirable to form within 90 degrees as the maximum apex angle.

The prism 1C is press-molded with a prism forming roll previously formed in a desired size and shape, and the prism base and the size of the prism forming roll are faithfully pressure-formed. The low hardness side of the material 1A is advantageous.
That is, the sheet base material 1A formed by coextrusion molding in the present invention is formed of a polycarbonate resin and a methacrylic resin, and the polycarbonate resin has a standard grade hardness (Rockwell M) of 75. On the other hand, the hardness (Rockwell M) in the standard grade of methacrylic resin is 90. Accordingly, the sheet base material 1A according to the present invention is formed on the side surface of the low-hardness polycarbonate, and the prism 1C is pressure-molded to form the various optical design creation base material 1 of the present invention.

Next, if the creation method of a variety of optical designs is explained together with the principle of creation using the various optical design creation substrates 1 of the present invention, facilities that consume or use the various optical design creation substrates 1 of the present invention In 2, natural light is directly or indirectly incident or artificial light is directly or indirectly incident and transmitted, whereby the various optical design creation substrates 1 are obtained by spectral dispersion, refraction, or lens action by the prism 1 </ b> C. It is to create various optical designs on the top.
Thus, since one side of the various optical design creation base material 1 is formed with a fine and enormous number of prisms 1C, when dust or the like adheres in practical use, it is the same for easy cleaning. It is desirable to laminate a protective layer 1D made of an extremely thin film of material.

Therefore, when natural light is used, the various optical design creation substrate 1 of the present invention is directly or indirectly incident and translucent at a facility where it is consumed or used, and thus created. For example, it can be placed on a place where a variety of optical designs appearing, that is, the daylighting ceiling 2A, the outer wall, the window 2B, or a door, can be stretched or attached to a translucent glass plate.
On the other hand, when using artificial light, it is processed into an umbrella 3A, a cover 3B, or a cover around the light source of the illuminating device 3 in the facility, and the artificial light is directly incident and transmitted, or inside the facility 2. The various optical design creation base materials 1 arranged in appropriate shapes and sizes in the appropriate positions are indirectly incident and transmitted to create various optical designs.

That is, FIG. 3 shows a specific example of a method for creating a variety of optical designs by incident light transmission of natural light 30, and FIG. 3A shows a variety of optical design creation base materials 1 on the daylighting ceiling portion 2 </ b> A of the facility 2. FIG. 3B shows a state in which various optical design creation base materials 1 are attached to the inner surface of the window 2B of the facility 2.
On the other hand, FIG. 4 shows a specific example of a method for creating a variety of optical designs using artificial light. FIG. 4A shows a method for creating artificial light 31 from the illuminator 3 using a variety of optical design creation substrates 1. FIG. 4B shows a state in which the artificial light beam 31 is used as the umbrella 3 </ b> A by the various optical design creation substrates 1.

Thus, the principle of creation and emergence of various optical designs that are created when natural light is directly or indirectly incident or transmitted when artificial light is directly or indirectly incident upon such use. On the low hardness side surface of the sheet base material 1A having excellent translucency and different hardness, a regular triangular pyramid shape or an isosceles triangle shape, and the length of each of the bottom three sides is approximately 160 to 450 μm, and from the bottom 4 to the top 4A. The height of the three sides is approximately 170 to 400 μm, and the extremely fine prism 1C is uniformly and uniformly pressed over the entire surface, so that the incident side of natural rays and artificial rays is 6 shows a planar state shown in FIG.
And the creation base material 1 of the various optical designs of the present invention is such that the natural light or artificial light that is transmitted through the incident light is spectrally dispersed, refracted and lensed by the prism 1C, and the creation of the various optical design creation base material 1 of the optical design. Since the surface is created, the length of the base 4 of the prism 1C, the height to the top 4A, etc. are formed within a maximum of 40% of the thickness with respect to the entire thickness. It is in.

And the expanded sectional explanatory drawing of 1 A of sheet base materials in which the prism 1C formed in such a huge number was formed is as showing in FIG.
That is, in FIG. 6, the normal incident light 40 </ b> A by natural light or artificial light is refracted into the prism 1 </ b> C according to the apex angle α of the prism 1 </ b> C and forms an optical design pattern 40 at an appropriate position on the sheet substrate 1 </ b> A. When natural light or artificial light is white light, spectral dispersion is also caused by the action of the prism 1C. Therefore, the image 4 has six radial spectra shown in FIG. A pattern 5A is created.
Furthermore, once natural light rays are once reflected and incident obliquely on various nearby objects such as 40B and 40C, the incident angles also vary, and the image 40 is separated and deformed into an indefinite shape and includes spectrally dispersed colored light. It is created as a pattern optical design pattern 5B.

  The emergence of the hexa-radial spectral pattern 5A by the normal incident light transmission of the natural ray is that the prism 1C formed as in the present invention has an equilateral triangular pyramid shape or an isosceles triangular pyramid, and the length of the base triangular length is respectively. By forming a large number of uniform and uniform prisms 1C having a length of 160 to 450 μm and a length from the base 4 to the top 4A of 170 to 400 μm, the characteristics of radiation in six directions are maintained. .

On the other hand, in the case of artificial light, when the incident light transmitted through it is white light and perpendicularly incident, a hexa-radial spectral pattern 5A is created as in the case of natural light direct incident light transmission.
However, a diffusion means for diffusing the artificial light into the light source is provided, and since the light source is close, the incident light to the substrate 1 for creating the various optical designs of the present invention is incident at multiple angles and is close to normal incidence. With the light beam and the lens action of the prism 1C, as shown in FIG.

Furthermore, since indirect rays by natural rays and artificial rays are reflected and transmitted through multiple angles, the light of the reflecting object is created together with the color-dispersed color light. The image created by light is created by creating a variety of optical designs. The reflected light is indirectly transmitted through the substrate 1 by reflecting the object at approximately 45 to 90 degrees with respect to the surface. Therefore, the creation of various optical designs is also a virtual imaging in which an imaging of a reflective object at a position of approximately 45 to 90 degrees is created.
Such a six-radial spectrum pattern 5A also changes to four radials when the incident angle changes greatly due to the movement of the natural light source, that is, the sun, and in particular in the case of artificial rays, it contains colored light depending on consumption or the viewing distance and angle of the user. The speckled pattern changes in a complex manner, and the fun, fun, novelty, and excitement are fully demonstrated.
