その拡散層は、複数個の拡散粒子及び粘着物質を含み、拡散粒子は粘着物質に埋め込むか、粘着物質に突出設置させる。そのため、拡散粒子が突出する、もしくは粘着物に埋め込むかに係わらず、どちらもその拡散層は目の粗い表面を形成し、光線が拡散層を経て外に射出した時、光線が拡散する。そのうち、この拡散粒子は透明の自然成形の球状物で、レンズの原理に基づき焦点を合わせると、光線を拡散させる。上述の公知技術において、拡散部品の原理は、主に細かな表面の粗度、もしくはレンズの原理を形成することに基づき、光線の拡散を均一にする機能を具える。また光学プラスチック、例としてポリスチレン、ポリメタクリル酸メチルエステル、ポリカーボネート等の材料は、その光学屈折率がおよそ１．４５〜１．６２前後で、高屈折率微粒状を上述の光学プラスチックに充填し、その分散が光学プラスチック内において、屈折率を高め、特定の波長の下、ゼロ反射を具えた抗反射物件となる。公知に技術に於いて、光学プラスチックに高屈折率の微粒を運用するのは、下記のもので、ナノ微頼粒を光学プラスチックに加えて抗反射の物件を改善する。
The diffusion layer includes a plurality of diffusion particles and an adhesive substance, and the diffusion particles are embedded in the adhesive substance or protruded from the adhesive substance. Therefore, regardless of whether the diffusing particles protrude or are embedded in an adhesive, the diffusion layer forms a rough surface, and when the light beam exits through the diffusion layer, the light beam diffuses. Among them, these diffusing particles are transparent, naturally shaped spheres that diffuse light when focused on the lens principle. In the above-described known technology, the principle of the diffusing component mainly has a function of making the light diffusion uniform based on forming a fine surface roughness or a lens principle. Moreover, optical plastics, such as polystyrene, polymethacrylic acid methyl ester, polycarbonate, and the like have an optical refractive index of about 1.45 to 1.62, and the above optical plastic is filled with the high refractive index fine particles, The dispersion increases the refractive index in the optical plastic, resulting in an anti-reflective article having zero reflection under a specific wavelength. In the known technology, high refractive index fine particles are used in optical plastics as follows, and nano fine particles are added to optical plastics to improve anti-reflection properties.
解決しようとする問題点は、光線が通過した屈折変化を更に高め、拡散をより平均化する点である。 The problem to be solved is that the change in refraction through which the light beam passes is further enhanced and the diffusion is more averaged.
本発明は、光を通す基板の一面上に一層もしくは複数層の相対屈折拡散層を設置し、また基板の別の一面には抗静電気密着層を設置する。この相対屈折拡散層は、一種以上の屈折率が異なる物質で構成され、形成された相対屈折拡散層は範囲のある相対屈折係数を具える。またこの相対屈折拡散層は一層もしくは多層で、多層の相対屈折拡散層は相互の屈折係数が一定の比例であることを最も主要な特徴とする。 In the present invention, one or a plurality of relative refractive diffusion layers are provided on one surface of a substrate through which light passes, and an anti-electrostatic adhesion layer is provided on another surface of the substrate. The relative refractive diffusion layer is made of one or more materials having different refractive indexes, and the formed relative refractive diffusion layer has a relative refractive index having a range. The relative refractive diffusion layer is a single layer or a multilayer, and the multilayer relative refractive diffusion layer is characterized in that the mutual refractive coefficient is a constant proportion.
本発明の光を屈折拡散する光学部品は、拡散層によって任意形状外形に形成された微粒子が光線通過の屈折変化を高め、光線が通過した時拡散がより均等になるという利点がある。 The optical component that refracts and diffuses light according to the present invention has the advantage that the fine particles formed into an arbitrary shape by the diffusion layer enhance the refractive change of the passage of light and the diffusion becomes more uniform when the light passes.
本発明の主な目的は、光を屈折拡散する光学部品を提供することで、拡散層によって任意形状外形に形成された微粒子が光線通過の屈折変化を高め、光線が通過した時拡散がより均等になる。 The main object of the present invention is to provide an optical component that refracts and diffuses light, so that fine particles formed into an arbitrary shape by the diffusion layer enhance the refractive change of light passage, and the diffusion is more uniform when the light passes. become.
本発明の次の目的は、複数の拡散層が輝度を高め、更に複数個の拡散層を使用して輝度効果を更に高める。 The next object of the present invention is to increase the luminance by the plurality of diffusion layers and further increase the luminance effect by using the plurality of diffusion layers.
上述の目的のため、光を屈折拡散する光学部品は、光を通す基板、一層もしくは複数層の相対屈折拡散層及び抗静電気密着層を含む。この基板の一面は相対屈折拡散層を設置し、基板の別一面には抗静電気密着層を設置する。相対屈折拡散層は一種以上の屈折率が異なる物質から構成され、形成された相対屈折拡散層は範囲のある屈折係数を具え、相対屈折拡散層は一層もしくは多層とし、その多層の相対屈折拡散層が相互に相対屈折係数一定の比例にする。そのため、光線が屈折係数の異なる材料を通過する時、その光線屈折角度は材料による屈折係数と異なった屈折が発生し、その屈折現象によって、通過した光線を拡散させ、少なくとも光線屈折角度の管理機能を具える。 For the above purpose, an optical component that refracts and diffuses light includes a substrate through which light passes, one or more layers of a relative refractive diffusion layer, and an anti-electrostatic adhesion layer. One surface of the substrate is provided with a relative refractive diffusion layer, and another surface of the substrate is provided with an anti-electrostatic adhesion layer. The relative refractive diffusion layer is composed of one or more substances having different refractive indexes, the formed relative refractive diffusion layer has a refractive index having a range, and the relative refractive diffusion layer is one layer or multiple layers. Are proportional to each other with a constant relative refraction coefficient. Therefore, when a light beam passes through a material having a different refraction coefficient, the refraction angle of the light beam is different from the refraction coefficient of the material, and the refraction phenomenon diffuses the light beam passing through, and at least the light refraction angle management function. With
図1は、本発明の光を屈折拡散する光学部品の第一実施例の指示図である。この光を屈折して拡散する光学部品1は、光を通す基板11、一もしくは複数の相対屈折拡散層12及び抗静電気密着層13を含む。この基板11の一面には相対屈折拡散層12を設置し、その基板11の別一面には抗静電気密着層13を設置する。相対屈折拡散層12は、少なくとも一種類以上の屈折率の異なる微粒子12a、及び光学材12bを混合して構成する。この微粒子12a任意の形状にすることができ、且つ微粒子12aの平均直径は２００μm〜２０ｎｍとする。良好なものとして、微粒子12aがこの相対拡散層12内に分布し、形成した相対屈折拡散層12が少なくとも０．２〜４．５の範囲の相対屈折係数を具えるものである。そのうち、この基板11はポリスチレン、ポリメタクリル酸メチルエステル、ポリカーボネート、ポリエチレン、ポリプロピレン、ポリ塩化ビニール、エポキシ樹脂、またはポリパラベンゼンカーボン酸工チルダイエステル等光学プラスチックとする。この基板11表面は粗度処理を行い、表面に一定の粗度を発生させ、拡散効果を高める。また微粒子12aは、光を通す有機の合成樹脂、もしくはその他の材料、例として金属、空気、化合物などを含む。光学材12bは光を通す有機の合成樹脂、例として熱塑性光学プラスチックもしくはＵＶ硬化の光固化式プラスチックを含む。 FIG. 1 is an instruction diagram of a first embodiment of an optical component that refracts and diffuses light according to the present invention. The optical component 1 that refracts and diffuses light includes a substrate 11 that transmits light, one or a plurality of relative refractive diffusion layers 12 and an anti-electrostatic adhesion layer 13. A relative refractive diffusion layer 12 is provided on one surface of the substrate 11, and an anti-electrostatic adhesion layer 13 is provided on another surface of the substrate 11. The relative refractive diffusion layer 12 is configured by mixing at least one kind of fine particles 12a having different refractive indexes and an optical material 12b. The fine particles 12a can have any shape, and the average diameter of the fine particles 12a is 200 μm to 20 nm. As a good example, the fine particles 12a are distributed in the relative diffusion layer 12, and the formed relative refractive diffusion layer 12 has a relative refractive index in the range of at least 0.2 to 4.5. Of these, the substrate 11 is an optical plastic such as polystyrene, polymethacrylic acid methyl ester, polycarbonate, polyethylene, polypropylene, polyvinyl chloride, epoxy resin, or polyparabenzene carbonic acid chilled diester. The surface of the substrate 11 is subjected to a roughness treatment to generate a certain roughness on the surface and enhance the diffusion effect. The fine particles 12a include an organic synthetic resin that transmits light, or other materials such as metal, air, and compounds. The optical material 12b includes an organic synthetic resin that transmits light, for example, a thermoplastic optical plastic or a UV-cured light-solidifying plastic.
この光学材12bと微粒子12aの間の総相対屈折係数は、以下の方程式でわかる。
この微粒子12aの屈折率は、光学材12bの屈折率より大きいか、もしくは小さいので、光の屈折拡散に面からみると、光線の光媒体が密か、そうでないかに係わらず、屈折現象が発生し、そのため絶対値によってその屈折率を計算する。 Since the refractive index of the fine particles 12a is larger or smaller than the refractive index of the optical material 12b, a refraction phenomenon occurs regardless of whether the optical medium of the light beam is dense or not. Therefore, the refractive index is calculated by the absolute value.
この光学材１２ｂが必要とする各微粒子１２ａの重量混合比例は、以下の公式で計算できる。
図2は、本発明の光を屈折拡散する光学部品の第二実施例指示図である。この光を屈折拡散する光学部品2は、光を通す基板11、複数層の相対屈折拡散層14、15及び抗静電気密着層13を含む。この墓板11の一面に多層の相対屈折拡散層14、15を設置し、基板11の別一面に抗静電気密着層13を設置する。この第一層の相対屈折拡散層14は、一種類以上の屈折率の異なる微粒子14aを含み、そのうち、この微粒子14aは任意の形状にできる。この微粒子14aの平均直径は２００μm〜２０ｎｍとし、形成する相対屈折拡散層14は０．２〜４．５の範囲の相対屈折係数を具える。第二層の相対屈折拡散層15は、一種類以上の屈折率を持つ異なる微粒子15a及び光学材料l5bを含む。そのうち、この微粒子l5aは任意の形状にできる。
この微粒子15aの平均直径は２００μｍ〜２０ｎｍで形成する相対屈折拡散層15は０．２〜５４．５の範囲の相対屈折係数を具える。本発明の第三層、第四層．．．等多層以上の相対屈折拡散層を含むが、重複するので詳述しない。この光学材14aと光学材15bの屈折係数は異なり、また微粒子14aと微粒子15aの屈折係数もまた異なる。そのため、第二実施例の光学部品は二層の相対屈折拡散層は二片の拡散片を使用して代替することができ、材料コストを大幅に下げることができる。
FIG. 2 is an instruction diagram of a second embodiment of an optical component that refracts and diffuses light according to the present invention. The optical component 2 that refracts and diffuses light includes a substrate 11 that transmits light, a plurality of relative refractive diffusion layers 14 and 15, and an anti-electrostatic adhesion layer 13. Multi-layered relative refractive diffusion layers 14 and 15 are installed on one surface of the grave board 11, and an anti-electrostatic adhesion layer 13 is installed on another surface of the substrate 11. The relative refractive diffusion layer 14 of the first layer includes one or more kinds of fine particles 14a having different refractive indexes, and of these, the fine particles 14a can have an arbitrary shape. The average diameter of the fine particles 14a is 200 μm to 20 nm, and the formed relative refractive diffusion layer 14 has a relative refractive coefficient in the range of 0.2 to 4.5. The relative refractive diffusion layer 15 of the second layer includes different fine particles 15a having one or more kinds of refractive indexes and the optical material l5b. Of these, the fine particles l5a can be in any shape.
The relative refractive diffusion layer 15 formed with an average diameter of the fine particles 15a of 200 μm to 20 nm has a relative refractive index in the range of 0.2 to 54.5. Third layer, fourth layer of the present invention. . . Although it includes a plurality of equal refractive layers or more, it overlaps and will not be described in detail. The optical material 14a and the optical material 15b have different refraction coefficients, and the fine particles 14a and the fine particles 15a also have different refraction coefficients. Therefore, in the optical component of the second embodiment, the two relative refractive diffusion layers can be replaced by using two pieces of diffusion pieces, and the material cost can be greatly reduced.
