Abstract
Description
本発明は、透明基材の表面に貼着される装飾用光透過性フィルム、該フィルムが透明基材の表面に貼着された光透過性装飾材および該装飾材を用いた照明器具に関する。 The present invention relates to a decorative light-transmitting film attached to the surface of a transparent substrate, a light-transmitting decorative material in which the film is attached to the surface of a transparent substrate, and a lighting device using the decorative material.
ガラス等の透明基材に装飾性を付与するために、透明基材の表面に装飾用フィルムを貼着したり、透明基材の表面に転写箔を転写したりすることが行われる。
装飾用フィルムとしては、例えば、下記のものが提案されている。
（１）多数の凹凸条からなるエンボスが設けられ、幅方向に一方から他方にかけて凹凸条のピッチおよび／または振幅がしだいに変化したガラス装飾用粘着フィルム（特許文献１）。
また、透明基材の表面に転写箔を転写した装飾材としては、例えば、下記のものが提案されている。
（２）エンボス層、隠蔽層、接着層を順次積層した構成で、該エンボス層に隣り合う単位模様の条模様の向きが異なるように複数の単位模様を組み合わせてなる凸模様を設けた転写箔を用いて、透明基材上に、周囲に透明部を存在させて多数の微細パターンを形成した装飾材（特許文献２）。
In order to impart a decorative property to a transparent substrate such as glass, a decorative film is attached to the surface of the transparent substrate, or a transfer foil is transferred to the surface of the transparent substrate.
For example, the following film has been proposed as a decorative film.
(1) An adhesive film for glass decoration in which embosses composed of a large number of concavo-convex strips are provided, and the pitch and / or amplitude of the concavo-convex strips gradually change from one to the other in the width direction (Patent Document 1).
Moreover, as a decorative material obtained by transferring a transfer foil onto the surface of a transparent substrate, for example, the following materials have been proposed.
(2) A transfer foil having a structure in which an emboss layer, a concealing layer, and an adhesive layer are sequentially laminated, and a convex pattern formed by combining a plurality of unit patterns so that the direction of the stripe pattern of the unit patterns adjacent to the emboss layer is different. A decorative material in which a large number of fine patterns are formed on a transparent base material with transparent portions in the periphery (Patent Document 2).
しかし、（１）のガラス装飾用粘着フィルムは、凹凸条のピッチおよび／または振幅の変化に応じて明るさが単純に変化するだけであり、意匠性に欠けるものである。
（２）の装飾材は、条模様の向きが異なるように複数の単位模様を組み合わせているため、意匠性は（１）のフィルムより高い。しかし、表裏面の絵柄を異ならせるために凸模様部に隠蔽層を設けているため、全体的に光透過性に乏しく、装飾材を設置している空間に閉塞感を与え、また、透過光による演出効果にも欠ける。
However, the pressure-sensitive adhesive film for glass decoration (1) simply changes in brightness according to changes in the pitch and / or amplitude of the ridges, and lacks design.
Since the decorative material of (2) combines a plurality of unit patterns so that the direction of the stripe pattern is different, the design property is higher than that of the film of (1). However, a concealing layer is provided on the convex pattern part to make the patterns on the front and back sides different, so the overall light transmission is poor, giving a feeling of blockage to the space where the decorative material is installed, and transmitted light It lacks the production effect.
本発明は、意匠性が高く、空間に開放感を与え、透過光による演出効果も有する装飾用光透過性フィルム、光透過性装飾材および照明器具を提供する。 The present invention provides a decorative light-transmitting film, a light-transmitting decorative material, and a lighting fixture that have high design properties, give a feeling of openness to a space, and also have an effect of transmitting light.
本発明の装飾用光透過性フィルムは、透明基材の表面に貼着される装飾用光透過性フィルムであって、複数の凸条およびまたは凹条が平行に形成された、光透過性を有する領域を複数有し、隣り合う領域で凸条およびまたは凹条の方向がそれぞれ異なることを特徴とする。 The decorative light-transmitting film of the present invention is a decorative light-transmitting film adhered to the surface of a transparent substrate, and has a plurality of convex stripes and / or concave stripes formed in parallel. There are a plurality of regions, and the direction of the ridges and / or the grooves is different between adjacent regions.
凸条およびまたは凹条の方向が同じ領域からなるグループの数は、２〜１２であることが好ましい。
本発明の光透過性装飾材は、透明基材と、該透明基材の表面に貼着された本発明の装飾用光透過性フィルムとを有することを特徴とする。
本発明の照明器具は、本発明の光透過性装飾材と、１つ以上の点光源とを具備することを特徴とする。

＜装飾用光透過性フィルム＞
本発明の装飾用光透過性フィルムは、透明基材の表面に貼着される装飾用光透過性フィルムであって、複数の凸条およびまたは凹条が平行に形成された、光透過性を有する領域を複数有し、隣り合う領域で凸条およびまたは凹条の方向がそれぞれ異なることを特徴とする。なお、隣り合う領域で凸条およびまたは凹条の方向が同じ場合、本発明においては、これら隣り合う２つの領域を１つの領域とみなす。
<Light transmissive film for decoration>
The decorative light-transmitting film of the present invention is a decorative light-transmitting film adhered to the surface of a transparent substrate, and has a plurality of convex stripes and / or concave stripes formed in parallel. There are a plurality of regions, and the direction of the ridges and / or the grooves is different between adjacent regions. In the case where the directions of the ridges and / or the ridges are the same in adjacent regions, in the present invention, these two adjacent regions are regarded as one region.
隣り合う領域で凸条およびまたは凹条の方向がそれぞれ異なることによって、凸条およびまたは凹条の方向が装飾用光透過性フィルム上に２種以上存在することになるため、装飾用光透過性フィルムの裏面側に点光源を配置し、装飾用光透過性フィルムの表面側から点光源を見た場合、点光源を中心にして、ここから放射状に延びる、凸条およびまたは凹条の方向の種類の数に対応した複数の光条（十字形、星形等）が現れる。以下、複数の光条が現れる効果を、光条効果と記す。 Since the directions of the ridges and / or grooves in the adjacent areas are different, two or more directions of the ridges and / or grooves are present on the decorative light-transmitting film. When a point light source is arranged on the back side of the film and the point light source is viewed from the front side of the decorative light-transmitting film, the point light source is the center, and the direction of the ridges and / or grooves extends radially from here. Multiple stripes (cross shape, star shape, etc.) corresponding to the number of types appear. Hereinafter, an effect in which a plurality of stripes appear is referred to as a stripe effect.
凸条およびまたは凹条の方向が同じ領域を１つのグループとすると、該グループの数は、２〜１２が好ましく、２〜８がより好ましい。隣り合う領域で凸条およびまたは凹条の方向がそれぞれ異なるようにするためには、該グループの数は最低でも２つ必要である。該グループの数が１２を超えると、隣接する光条間の角度が小さくなり、光条をはっきりと認識しにくくなる。 When the area | region where the direction of a protruding item | strip and / or a concave strip is the same is made into one group, 2-12 are preferable and, as for the number of this group, 2-8 are more preferable. In order to make the directions of the ridges and / or ridges different in adjacent regions, the number of the groups is at least two. If the number of the groups exceeds 12, the angle between adjacent light stripes becomes small, and it becomes difficult to clearly recognize the light stripes.
各グループ間での凸条およびまたは凹条の方向の角度差の最小値は、１０度以上が好ましく、１５度以上がより好ましい。角度差の最小値が１０度未満では、隣接する光条が重なって見える場合がある。 The minimum value of the angle difference in the direction of the ridges and / or ridges between the groups is preferably 10 degrees or more, and more preferably 15 degrees or more. If the minimum value of the angle difference is less than 10 degrees, adjacent light stripes may appear to overlap each other.
各領域の面積は、０．１〜５００ｍｍ２が好ましく、１〜３００ｍｍ２がより好ましい。領域の面積が０．１ｍｍ２以上であれば、光条が明確に現れる。領域の面積が５００ｍｍ２以下であれば、光条効果が現れやすくなる。 The area of each region is preferably 0.1~500mm 2, 1~300mm 2 is more preferable. If the area of the region is 0.1 mm 2 or more, the light stripe appears clearly. If the area of the region is 500 mm 2 or less, the light stripe effect tends to appear.
凸条間（または凹条間）の間隔は、０．１〜２００μｍが好ましく、１〜１００μｍがより好ましい。凸条間（または凹条間）の間隔が０．１μｍ以上であれば、凸条（または凹条）の成形において欠陥が発生しにくい。凸条間（または凹条間）の間隔が２００μｍ以下であれば、光条が明確に現れる。 The interval between the protrusions (or the recesses) is preferably 0.1 to 200 μm, and more preferably 1 to 100 μm. If the distance between the ridges (or between the ridges) is 0.1 μm or more, defects are not likely to occur in the formation of the ridges (or ridges). If the distance between the ridges (or between the ridges) is 200 μm or less, the light stripes appear clearly.
凸条（または凹条）と平坦部の幅の比は、４：１〜１：３が好ましく、３：１〜１：２がより好ましい。凸条（または凹条）と平坦部の幅の比が該範囲内であれば、透光率を十分確保でき、かつ、目隠し効果を付与することが可能である。 The ratio of the width of the ridge (or ridge) to the flat portion is preferably 4: 1 to 1: 3, and more preferably 3: 1 to 1: 2. If the ratio of the width of the ridges (or ridges) to the flat portion is within this range, it is possible to sufficiently ensure the light transmittance and to impart a blinding effect.
凸条の高さ（または凹条の深さ）は、凸条（または凹条）の幅とほぼ同程度であることが好ましい。凸条の高さ（または凹条の深さ）が凸条（または凹条）の幅とほぼ同程度であれば、凸条（または凹条）成形において欠陥が発生しにくい。 It is preferable that the height of the ridge (or the depth of the ridge) is approximately the same as the width of the ridge (or the ridge). If the height of the ridges (or the depth of the ridges) is approximately the same as the width of the ridges (or ridges), defects are less likely to occur in the formation of the ridges (or grooves).
凸条およびまたは凹条の形成方法としては、凸条およびまたは凹条に対応した凹条およびまたは凸条が表面に形成された精密エンボス版（特開平０５−０２７４０８号公報等参照）を用い、ベースフィルムの表面をエンボス加工する方法；凸条に対応した凹条が表面に形成されたグラビア印刷版を用い、透明インキからなる凸条をベースフィルムの表面に形成する方法；インクジェット印刷機により透明インキからなる凸条をベースフィルムの表面に形成する方法；電離放射線硬化樹脂からなる凸条をベースフィルムの表面に形成した後、紫外線、電子線等の電離放射線を照射して硬化させる方法；別にあらかじめ形成した凸条を熱転写によりベースフィルムの表面に形成する方法等が挙げられる。 As a method for forming the ridges and / or ridges, a precise embossed plate (see Japanese Patent Application Laid-Open No. 05-027408 etc.) in which ridges and / or ridges corresponding to the ridges are formed on the surface, A method of embossing the surface of the base film; a method of forming ridges made of transparent ink on the surface of the base film using a gravure printing plate having ridges corresponding to the ridges formed on the surface; transparent by an ink jet printer Method of forming ridges made of ink on the surface of the base film; Method of forming ridges made of ionizing radiation curable resin on the surface of the base film and then curing by irradiating with ionizing radiation such as ultraviolet rays and electron beams; Examples thereof include a method of forming a pre-formed protrusion on the surface of the base film by thermal transfer.

図５は、本発明の装飾用光透過性フィルムの第３の実施形態を示す平面図である。

(Third embodiment)
FIG. 5 is a plan view showing a third embodiment of the decorative light-transmitting film of the present invention.
Note that in the third embodiment, the same components as those in the first embodiment are denoted by the same reference numerals as in FIG. 1 and description thereof is omitted.
第３の実施形態においては、凸条１２の方向が同じ領域からなるグループの数は６つである。

When the direction of the ridges 12 in the region A belonging to the first group is 0 degree, the direction of the ridges 12 in the region B belonging to the second group is 30 degrees in the clockwise direction, and the third The direction of the ridges 12 in the region C belonging to the group is 30 degrees in the counterclockwise direction, the direction of the ridges 12 in the region D belonging to the fourth group is 60 degrees in the clockwise direction, The direction of the ridges 12 in the region E belonging to the fifth group is 60 degrees counterclockwise, and the direction of the ridges 12 in the region F belonging to the sixth group is 90 degrees.
第３の実施形態においては、装飾用光透過性フィルム１０の裏面側に点光源を配置し、装飾用光透過性フィルム１０の表面側から点光源を見た場合、図６に示すような、点光源を中心にしてここから放射状に延びる１２本の光条が現れる。隣接する光条間の角度は、それぞれ約３０度となる。 In the third embodiment, when a point light source is disposed on the back side of the decorative light transmissive film 10 and the point light source is viewed from the front surface side of the decorative light transmissive film 10, as shown in FIG. Twelve light strips appear radially extending from here around the point light source. The angle between adjacent light strips is about 30 degrees.
なお、本発明の装飾用光透過性フィルムは、第３の実施形態に示すように、各領域間に凸条およびまたは凹条が形成されていない間隙を有していてもよい。各領域間に凸条およびまたは凹条が形成されていない間隙を形成することにより、各領域の形状がよりはっきりと浮かび上がり、装飾用光透過性フィルムの意匠性が向上する。 In addition, as shown in 3rd Embodiment, the light-transmitting film for a decoration of this invention may have the clearance gap in which the protruding item | line and / or the concave item | line are not formed between each area | region. By forming a gap in which no ridges and / or ridges are formed between the regions, the shape of each region emerges more clearly and the design of the decorative light-transmitting film is improved.
以上説明した本発明の装飾用光透過性フィルムにあっては、複数の凸条およびまたは凹条が平行に形成された、光透過性を有する領域を複数有し、隣り合う領域で凸条およびまたは凹条の方向がそれぞれ異なるため、領域ごとに光の反射や光の透過の具合が異なる。そのため、光の入射角によって、領域ごとのさまざまな形状が浮かび上がったり、領域ごとに濃淡が現れたりするため、意匠性が高い。
また、凸条およびまたは凹条が形成された領域が光透過性を有しているため、フィルムの向こう側が透けて見え、空間に明るい開放感を与えることができる。
また、上述したような光条効果が現れるため、透過光による幻想的な空間の演出も可能である。
In the decorative light-transmitting film of the present invention described above, a plurality of ridges and / or ridges are formed in parallel, each having a plurality of light-transmitting regions, Alternatively, since the direction of the concave stripes is different, the degree of light reflection and light transmission is different for each region. For this reason, depending on the incident angle of light, various shapes appear for each region, and shading appears for each region, so that the design is high.
Moreover, since the area | region in which the protruding item | line and / or the recessed item | line were formed has a light transmittance, the other side of a film can be seen through, and a bright open feeling can be given to space.
In addition, since the streak effect as described above appears, it is possible to produce a fantastic space by transmitted light.
＜装飾材＞
本発明の光透過性装飾材は、透明基材と、該透明基材の表面に貼着された本発明の装飾用光透過性フィルムとを有することを特徴とする。
<Decoration materials>
The light-transmitting decorative material of the present invention is characterized by having a transparent substrate and the decorative light-transmitting film of the present invention attached to the surface of the transparent substrate.
透明基材の材料としては、ガラス、ポリカーボネート、アクリル樹脂、塩化ビニル樹脂、ポリエチレンテレフタレート等が挙げられる。
透明基材は、既設のものであってもよい。既設の透明基材としては、窓ガラス、ショウウインドウ、ショーケースのガラス、透明パーティション、照明器具の前面カバー等が挙げられる。

The transparent substrate may be an existing one. Examples of the existing transparent substrate include window glass, show window, showcase glass, transparent partition, and front cover of a lighting fixture.
以上説明した本発明の光透過性装飾材にあっては、透明基材の表面に本発明の装飾用光透過性フィルムを貼着しているため、意匠性が高く、空間に開放感を与え、透過光による演出効果（光条効果）も有する。 In the light-transmitting decorative material of the present invention described above, the decorative light-transmitting film of the present invention is stuck on the surface of the transparent substrate, so that the design is high and the space is given a sense of openness. There is also a production effect (light stripe effect) by transmitted light.
＜照明器具＞
本発明の照明器具は、本発明の光透過性装飾材と、１つ以上の点光源とを具備するからなることを特徴とする。
<Lighting equipment>
The lighting fixture of the present invention comprises the light-transmitting decorative material of the present invention and one or more point light sources.
点光源としては、白熱電球、ハロゲンランプ、ＨＩＤランプ、キセノンランプ、ＬＥＤ（発光ダイオード）等が挙げられる。消費電力に対する発光効率が高く、かつ、発熱量が比較的小さい点から、ＬＥＤが好ましい。 Examples of the point light source include an incandescent lamp, a halogen lamp, an HID lamp, a xenon lamp, and an LED (light emitting diode). An LED is preferable because of its high luminous efficiency with respect to power consumption and relatively small amount of heat generation.
本発明の照明器具においては、点光源から放出された光が本発明の光透過性装飾材を介することによって、点光源を中心にしてここから放射状に延びる光条が現れる。
点光源の数は、照明器具の用途と大きさにより、１つでもあってもよく、２つ以上であってもよい。また、照明器具が、例えば壁面等の大面積にわたるものであれば、透明基材の表面の点光源を覆う部分のみに光条効果を発現する本発明の装飾用光透過性フィルムを設けてもよいし、光条効果を発現する凸条（または凹条）を装飾用光透過性フィルムの一部に設け、対応する部分に点光源を設置してもよい。
In the luminaire of the present invention, the light emitted from the point light source passes through the light-transmitting decorative material of the present invention, so that a light strip extending radially from the point light source appears.
The number of point light sources may be one or may be two or more depending on the use and size of the lighting fixture. Further, if the lighting fixture covers a large area such as a wall surface, the decorative light-transmitting film of the present invention that exhibits the streak effect only on the portion covering the point light source on the surface of the transparent substrate may be provided. Alternatively, protrusions (or recesses) that exhibit a light stripe effect may be provided in a part of the decorative light-transmitting film, and a point light source may be provided in the corresponding part.
