Description

本発明は自然光線や人工光線を透光させて、スペクトルの分散並びに屈折及びレンズ作用による多彩な光学意匠の創出と、且視認距離並びに視認角度により複雑に変化する、多彩な光学意匠の創出方法及び創出基材に関する。  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.

我が国では経済成長期を経て経済規模も一段と拡大化し、これとともに生活水準も著しく向上したこととも相俟って、消費行動も極めて多様化している。即ち食生活における中食化や外食化を初め、車利用によるアウトドアライフの増大、余暇の増加に伴う主婦の就労化や絵画、音楽、観劇或いはカルチャースクールでの習学、更には健康指向を背景として温泉や温浴施設若しくはリゾート施設利用の増大等多岐多様な消費行動がなされている。  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.

これがため都市部はもとより、郊外においても外食化に対処する膨大数の外食店舗や、健康指向に対処する温浴施設や健康ランド、或いはエステサロン施設等が、更にはレジャー施設やリゾート施設等までも林立するに至っている。
加えて近年に至っては、これらの消費行動の増大化を見据えて外国資本や外国企業が続々と参入していることから、これら企業間では熾烈な競争が展開されており、新規参入の反面において多くの敗退企業も発生している。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.

そしてかかる敗退企業の多くは、ひたすら提供する財やサービスの低価格を以って集客を図った結果によるものとされているが、現状の消費者や利用者は十分な購買力を保有しており、且情報化を背景として多種の財やサービスの情報を知り得るものであるから、単に価格的安価さや品質よりも消費若しくは利用する環境や雰囲気、即ち消費や利用する楽しさ、面白さ、心地良さ、斬新さ、奇抜さと安全並びに安心さ等を求めて消費若しくは利用行動がなされており、これが集客性と且経営維持のための要点とされている。
そして施設環境の改善のために大胆な内外装の改修がなされるケースも散見されるが、莫大な改修費用に加えて長期の休業も余儀なくされ、而も仮令斬新的内外装がなされても施設の構造面での変更に過ぎず、反面消費若しくは利用者は老若男女に亘るものであるから、広範囲の消費若しくは利用者の満足する環境や雰囲気の創出が不可欠とされている。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.

而して近年に至り施設内の照明を直接的並びに間接的に配し若しくは色光の使用により環境や雰囲気の改善を図ることも試みられているが、落ち着き感や柔かさ等が加重されるものの、結局は固定された環境や雰囲気等を改善するまでには至らず、且照明装置のための設備コストに加え大きな電力も必要とする。  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.

かかる実情に鑑み発明者等は鋭意研究を重ねた結果、発明者等が既に開発上市している合成樹脂フィルムの一側面に光再帰加工を施し、車輛ヘッドライトの光線を全反射再帰せしめて、遠距離での危険物の確実な視認をなさしめ、以って安全確保を図る光再帰性反射フィルムの光反射機能に加えて、光透過機能について更なる研究を重ねた結果、透光性シートの一側面全体に正三角錐若しくは二等辺三角錐形の微細且多数のプリズム加工を施してなる創出基材に光線透光をなすと、スペクトル分散作用や屈折作用並びにレンズ作用と且透光光線の入射角度及び視認角度により極めて多彩で多色に亘る光学意匠模様が創出されることを究明し本発明に至った。
特公平８−１１８７４号公報 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

本発明は消費や利用に供する施設の外面若しくは内面の適宜位置に配置させ、自然光線若しくは人工光線を直接或いは間接的に透光せしめて、多彩な光学意匠を創出且変化させて、施設内の環境や雰囲気を楽しさ、面白さ、奇抜さに溢れる新規の空間に改善することの可能な、多彩な光学意匠の創出方法、及び創出基材の提供にある。  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.

上述の課題を解決するために本発明が採用した技術的手段は、自然光線や人工光線の透光性に優れ且光線による劣化、特には紫外線を多量に含む自然光線からの長期に亘る耐光性能を保持させること、及びその一側面全体に微細で且均等なプリズム加工を形成するうえで、該一側面が他側面より低硬度のものが好適であることから、透光性に優れ且硬度の異なるポリカーボネート樹脂及びメタクリル樹脂を共押出しにより、一体的二層構造で所要の厚さに成形させてシート基材となしたるうえ、該シート基材の低硬度な側面全体に亘って、正三角錐形状若しくは二等辺三角錐形状で微細且連接して多数のプリズムを加圧成形させて、多彩な光学意匠の創出基材となすものである。  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.

更に該多彩な光学意匠の創出基材は、透光性と耐光性に優れるとともに硬度の異なる二層で且その低硬度の側面にプリズムを加圧成形させたものでも多彩な光学意匠の創出がなしえるものであるから、前記共押出しによる一体的二層構造による以外、透光性に優れ且硬度の異なるニトロセルロース、セルローストリアセテート、セルローストリブチレートからなるフィルム材やポリエステル若しくはポリアミド或いはポリスチレンフィルム材を透光性バインダーにより二層に積層させたうえ、その低硬度の積層フィルム面にプリズムを加圧成形させたものも使用できる。  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.

更にかかる多彩な光学意匠の創出基材を実用使用に供する場合に、そのプリズム面には膨大数の微細凹凸が形成されてなり、長期使用に伴う塵埃の付着による光線透過の阻害を防止するうえから、該創出基材を形成する素材からなる極薄フィルムによる防護層をプリズム面に積層させた構成に存するものである。  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.

かかる如くして形成された多彩な光学意匠の創出基材を用いて多彩な光学意匠を創出させる方法は、消費者若しくは利用者が利用する施設等の自然光線が直接照射され若しくは間接的に照射され透光される場所に張設若しくは貼着させることにより、自然光線の直接入射透光によりスペクトル分散された六放射状のスペクトル模様が創出現出され、間接入射透光によってはその入射角に伴う屈折光により不定形のスペクトル斑模様が随所に創出現出される。
加えて多彩な光学意匠の創出基材を広面積で張設若しくは貼着させれば、前記六放射状のスペクトル模様等は全面に亘って創出現出され、且視認角度により該スペクトル模様は変形消失され、更に多彩な光学意匠の創出基材を分割して張設若しくは貼着させれば、それぞれに六放射状のスペクトル模様若しくは不定形スペクトル斑模様が創出現出される。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.

更に人工光線においては、その光源即ち照明具からの発光光線を透光させるような笠やカバー若しくは覆いとして配置させることにより、発光光線が白色光に近似するものであればスペクトル分散された六放射状のスペクトル模様が創出現出され、且該白色光線を間接的に照射させることにより不定形スペクトル斑模様が随所に創出現出されるとともに、視認角度により該スペクトル斑模様は多様に変化して創出現出される。  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.

本発明は上述の如く透光性に優れ且硬度の異なる合成樹脂素材を用いて共押出しによる一体的二層構造若しくはそれぞれの合成樹脂素材からなるシート材を積層構造となしたシート基材が用いられ、且その低硬度の側面全体に正三角錐形状若しくは二等辺三角錐形状の微細で多数のプリズムを均等に加圧成形させる場合に極めて精度の高い加圧成形が能率的になしえるとともに、均質且高精度のプリズムが形成された創出基材が形成されるため、入射透光される自然光線や人工光線が良好にスペクトル分散や屈折されて、鮮明で且多彩な光学意匠模様が創出現出されることとなる。  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.

加えて該創出基材は異なる合成樹脂素材が用いられるため、実用使用に際して要請される耐候性や耐光性、耐熱性或いは引張強力や曲げ強力等も選択する合成樹脂素材により相互補填がなしえる。
更に本発明の多彩な光学意匠の創出方法は、施設等の採光天井、外壁、窓若しくは扉等に広面積で若しくは小面積に分割のうえ張設若しくは貼着させて自然光線を直接若しくは間接的に入射透光させ、若しくは人工光線の白色光を直接若しくは間接的に入射透過させることで実施しえるため、設置コストの負担や新たな電源装置や光源の設置費用ばかりか、電力費用の負担も不用となる。
そして本発明創出基材のプリズム面に防護層が形成されたものでは、長期使用により塵埃等の付着がなされても、該防護層表面は平滑であるから、清掃除去も簡便になしえる。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.

ポリカーボネート樹脂及びメタクリル樹脂を共押出しにより、厚さ０．５ｍｍの一体的二層構造押出し成形されたシート基材の低硬度の側面全体に、正三角錐形状若しくは二等辺三角錐形状で微細且膨大数のプリズムを加圧成形させて創出基材となすとともに、全天候のレジャー施設の採光天井に所要の面積を以って直接張設し若しくはガラス屋根の内面に貼着される。  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.

以下に本発明実施例を図とともに詳細に説明すれば、図１のＡには本発明多彩な光学意匠の創出基材１を形成するための、共押出し成形によるシート基材１Ａの説明図であって、該シート基材１Ａは優れた透光性はもとより、長期使用に際しても適応できる耐候性や耐光性、耐熱性或いは引張り強力並びに曲げ強力等の強靭性を保持することは無論、プリズム１Ｃの加圧成形に際してはその一側面が低硬度のものが望まれる。
ここで優れた透光性を保持する合成樹脂素材としては、ポリカーボネート樹脂やメタクリル樹脂に加えてポリエステル樹脂、ポリアミド樹脂、ポリスチレン樹脂、ポリ塩化ビニル樹脂の他、ニトロセルロース樹脂、セルローストリアセテート樹脂或いはセルローストリブチレート樹脂等が挙げられるが、実用使用に際しての性能にも対処するうえからは、それぞれの合成樹脂素材の持つ性能を有効に選択組合せて相互補完を図ることが好都合である。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.

加えて肝要なことは、これらから選択された合成樹脂素材を共押出し成形により一体的二層構造に成形させることが、透光性を阻害させず且均質な物理的性能を発揮させるうえで望まれるが、かかる合成樹脂相互の共押出しに際しては相互の合成樹脂素材の相溶性が不可欠となる。これがため本発明においては、ポリカーボネート樹脂とメタクリル樹脂とにより共押出し成形させたシート基材１Ａが、その一つとして選択される。無論かかる合成樹脂素材以外にも、相互の相溶性や成形条件により共押出し成形が可能であれば採用できる。  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.

反面透光性に優れるニトロセルロール樹脂やセルローストリアセテート樹脂、或いはセルローストリブチレート樹脂等は、共押出し成形が至難であることから、一旦それぞれの合成樹脂素材で高硬度の透光性フィルム材１０Ｂを形成したうえ、使用性能を補完でき且低硬度の透光性フィルム材１１Ｂとを、透光性バインダー１１Ｃを用いて一体的二層構造に積層させたシート基材１Ｂも使用可能である。そしてかかるシート基材１Ａ若しくはシート基材１Ｂの厚さは、使用目的により異なるが略０．３乃至１．０ｍｍ程度に形成される。  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.

かくして一体的二層構造に形成されたシート基材１Ａは、図２に示すように、その硬度の低い側面１１Ａ全体に亘って正三角錐形状若しくは二等辺三角錐形状の微細且膨大数のプリズム１Ｃが均等且均質に加圧成形により形成される。
このプリズム１Ｃの大きさはシート基材１Ａ若しくはシート基材１Ｂの厚さにもよるが、本発明では略０．３乃至１．０ｍｍ程度のものが使用されるものであるから、正三角錐形状若しくは二等辺三角錐の場合では底三辺の長さは略１６０乃至４５０μｍ程度、底辺から頂部までの高さ三辺の長さとしては略１７０乃至４００μｍ程度の大きさで形成される。そして正三角錐形状では自然光線若しくは人工光線の入射透光に際しての光線のスペクトル分散や屈折に関与するプリズム１Ｃの頂部から底三辺に至る頂角は６０度で形成されるが、二等辺三角錐形状においても最大頂角として９０度程度以内に形成させることが望ましい。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.

そしてかかるプリズム１Ｃは、所望の寸法形状で予め形成されたプリズム成形ロールで加圧成形されるものであり、且該プリズム成形ロールのプリズム形状や寸法を忠実に加圧成形させるうえから、シート基材１Ａの低硬度の側面が好都合となる。
即ち本発明における共押出し成形により形成されるシート基材１Ａはポリカーボネート樹脂と、メタクリル樹脂とにより形成されるもので、ポリカーボネート樹脂は標準グレードでの硬度（ロックウエルＭ）は７５である。他方メタクリル樹脂の標準グレードにおける硬度（ロックウエルＭ）は９０である。従って本発明におけるシート基材１Ａにおいては低硬度なポリカーボネート側面に形成がなされるもので、かかるプリズム１Ｃが加圧成形されることにより、本発明多彩な光学意匠創出基材１が形成される。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.

次いでかかる本発明多彩な光学意匠創出基材１を用いて、多彩な光学意匠の創出方法をその創出原理とともに説明すれば、本発明多彩な光学意匠創出基材１を、消費若しくは利用される施設２において自然光線が直接的若しくは間接的に或いは人工光線を直接的若しくは間接的に入射透光させることにより、そのプリズム１Ｃによるスペクトル分散や屈折或いはレンズ作用により、該多彩な光学意匠創出基材１の上に多彩な光学意匠を創出現出させることにある。
而して該多彩な光学意匠創出基材１の一側面には微細且膨大数のプリズム１Ｃが形成されてなるため、実用使用に際して塵埃等が付着した場合に、洗浄を容易をするうえから同一素材の極薄フィルムからなる防護層１Ｄを積層させることが望ましい。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.

これがためには自然光線を利用する場合には、本発明多彩な光学意匠創出基材１を、消費若しくは利用される施設において自然光線が直接的若しくは間接的に入射透光され、且これにより創出現出される多彩な光学意匠を視認できる場所、即ち採光天井２Ａ、外壁、窓２Ｂ若しくは扉等に張設し或いは透光ガラス板に貼着させること等が挙げられる。
他方人工光線を利用する場合には、施設内の照明具３の光源の周りに傘３Ａやカバー３Ｂ若しくは覆い等に加工したうえ包被させて人工光線を直接入射透光させ、或いは施設２内の適宜位置に適宜の形状及び大きさに配設させた多彩な光学意匠創出基材１に間接的に入射透光させて、多彩な光学意匠を創出現出させるものである。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.

即ち図３には自然光線３０の入射透光による多彩な光学意匠の創出方法の具体例が示されてなり、図３のＡは施設２の採光天井部分２Ａに多彩な光学意匠創出基材１が使用された状況であり、図３のＢには施設２の窓２Ｂの内側面に多彩な光学意匠創出基材１が貼着された状態が示されている。
他方図４には人工光線による多彩な光学意匠の創出方法の具体例が示されてなるもので、図４のＡには照明具３からの人工光線３１を多彩な光学意匠創出基材１によるカバー３Ｂで包被させた場合が示されてなり、同図４のＢには人工光線３１を多彩な光学意匠創出基板１による傘３Ａとして使用する状態が示されている。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.

而してかかる使用に際して自然光線が直接的若しくは間接的に、或いは人工光線が直接的若しくは間接的に入射透光される場合に創出現出される多彩な光学意匠の創出現出原理を述べれば、透光性に優れ且硬度の異なるシート基材１Ａの低硬度側面に、正三角錐形状若しくは二等辺三角形状で且それぞれの底三辺の長さが略１６０乃至４５０μｍ、及び底辺４から頂部４Ａまでの高さ三辺の長さも略１７０乃至４００μｍと極めて微細なプリズム１Ｃが全面に亘って膨大数で均等且均質に加圧成形されてなるものであるから、自然光線や人工光線の入射側面は図５に示す平面状態を示している。
そして本発明多彩な光学意匠の創出基材１は、入射透光される自然光線や人工光線を、そのプリズム１Ｃによりスペクトル分散や屈折及びレンズ作用により、該多彩な光学意匠の創出基材１の面に創出現出させるものであるから、その全体の厚さに対してプリズム１Ｃの底辺４の長さ及び頂部４Ａまでの高さ等が、厚さに対して最大４０％以内に形成させることにある。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.

そしてかかる膨大数で形成されるプリズム１Ｃが形成されたシート基材１Ａの拡大断面説明図は図６に示す通りである。
即ち図６において自然光線や人工光線による垂直入射光線４０Ａはプリズム１Ｃの頂角αの角度に従いプリズム１Ｃ内に屈折しシート基材１Ａの適宜位置に光学意匠模様を結像４０することとなる。そして自然光線や人工光線が白色光線である場合にはプリズム１Ｃの作用によりスペクトル分散もなされるから、該結像４にはスペクトル分散された色光が包含された図７のＡに示す六放射状スペクトル模様５Ａが創出現出される。
更に４０Ｂや４０Ｃの如く自然光線が近傍の諸物体に一旦反射されて傾斜入射されると、その入射角も多様となり、結像４０が不定形状に分離変形されてスペクトル分散された色光を含む斑模様の光学意匠模様５Ｂとして創出現出される。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.

この自然光線の垂直入射透光により六放射状のスペクトル模様５Ａの創出現出は、本発明の如く形成されるプリズム１Ｃが正三角錐形状若しくは二等辺三角錐で、且底三角長の長さがそれぞれ１６０乃至４５０μｍ、底辺４から頂部４Ａまでの長さが１７０乃至４００μｍの微細なプリズム１Ｃとして膨大数で均等且均質に形成された場合には、六方向への放射をなす特質を保持することによる。  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. .

他方人工光線においては、その入射透光する光線が白色光で且垂直の入射の場合では自然光線の直接的入射透光と同様に六放射状スペクトル模様５Ａが創出現出される。
而しながら人工光線はその光源に光拡散させる拡散手段が講じられ、且光源も至近なため本発明多彩な光学意匠の創出基材１への入射光線は多角度で入射され、垂直入射に近い光線とプリズム１Ｃのレンズ作用とにより図７のＣに示すように六放射状方向に光源を六結像５Ｃに拡大して創出現出がなされる。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.

更に自然光線や人工光線による間接光線は多角度で反射されて入射透光されるため、該反射物体の光がスペクトル分散された色光とともに創出現出されるものであるが、これら間接光線が入射透光されて創出現出される結像は、該多彩な光学意匠の創出基材１には、その表面に対して略４５乃至９０度近くの反射物体も反射光線が間接的に入射透光されるため、多彩な光学意匠の創出基材１には略４５乃至９０度の位置の反射物体の結像が創出現出される仮想結像でもある。
そしてかかる六放射状スペクトル模様５Ａも自然光線の光源即ち太陽の移動により大きく入射角が変化すると４放射状に変化し、とりわけ人工光線による場合には、消費若しくは利用者の視認距離や角度により色光を含む斑模様が複雑に変化し、楽しさや面白さ、斬新さや奇抜さも十分に発揮される。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.
