Description

  The present invention relates to a light-transmitting or semi-light-transmitting plate-like body including a light guide light emitting element, and is suitable for application to, for example, a window glass for buildings or automobiles.

  As this type of plate-like body, Patent Document 1 discloses that a panel body is formed by sintering and integrating a fabric woven from a plurality of side-emitting optical fibers between two transparent glass plates.

U.S. Pat. No. 4,234,907 Japanese Utility Model Publication No. 6-79599 JP-A-4-56806

By the way, in the surface emitting panel described in Patent Document 1, a long optical fiber that does not contribute to aesthetics is unfavorable because it protrudes to the outside, and when the panel is installed or transported, it protrudes. Is bothersome and inconvenient. In addition, the protruding optical fiber may be damaged by careless handling.
Moreover, since the light decoration panel apparatus of patent document 2 is an idea of adding the function to let light pass to the inherently opaque concrete panel board, the glass plate etc. which already have the function to let light pass through The transparent panel board has an unrelated idea.

  Further, the fluorescent optical fiber embedded in the transparent panel described in Patent Document 3 is a side-receiving optical fiber, and a side-emitting type that emits colored fluorescence from all sides along the length direction of the optical fiber. Since it is also an optical fiber, it is substantially a panel plate with a fluorescent pattern, and the colorless transparency of the transparent panel plate is lost accordingly. In addition, if the length of the fluorescent optical fiber exceeds 10 cm, the light incident on the light incident end side (or the generated fluorescence) is emitted on the side surface in the middle, so that it does not reach the light emitting end side. There are also drawbacks.

    The present invention has been made in view of the above circumstances, and is a plate-like body provided with a light guide light emitting element that can enhance the function and aesthetics of the transparent plate-like body without impairing the original transparency of the transparent plate-like body. And an object of the present invention is to provide a manufacturing method thereof.

    In order to solve the above-described problems, the configuration of the present invention relates to a translucent or semi-transparent plate-like body having a front surface and a back surface that face each other with a thick portion interposed therebetween, and the front surface side or the back surface side. From the front surface side or the back surface side, as the functional light or the impression light that propagates the light incident on the thick part from along the predetermined path that crawls through the thick part and enhances the function or aesthetics of the plate-like body One or more light guide members for emitting light to the outside are embedded in the plate-like body.

  According to the configuration of the present invention, since the light guide member is embedded in the plate-like body, the appearance beauty of the transparent plate-like body is not impaired, and the handling becomes easy. Further, even if a dedicated light source is not used, external light is picked up and shines, which is suitable for power saving. In addition, with a simple configuration, it is possible to emit impression light (design light) that enhances the appearance of the transparent plate without losing the original transparency of the transparent plate, or the function of the transparent plate Functional light such as enhanced display light can be emitted to the outside.

It is a perspective view which shows the structure of the window glass (transparent plate-shaped object) provided with the aesthetic light emitting element or functional light emitting element of the light guide structure which is 1st Example of this invention. It is a figure which shows the structure of the window glass (transparent plate-shaped object) provided with the aesthetic light emitting element or functional light emitting element of the light guide structure which is 2nd Example of this invention. It is a figure which shows operation | movement of the window glass. In the window glass, it is a figure which shows the structure by which the LED light source unit is mounted | worn with the LED mounting part. It is a perspective view which shows the structure of the window glass (transparent plate-shaped object) provided with the aesthetic light emitting element or functional light emitting element of the light guide structure which is the 3rd Example of this invention. It is a figure which shows operation | movement of the window glass.

    The plate-like body of the present invention can be applied to a window glass for buildings and automobiles, and can also be applied to, for example, a door glass for a shelf / cupboard, a table glass, and the like. Furthermore, the present invention can be widely applied to partition plates, interior plates, and decorative plates.

Embodiment 1

Hereinafter, a preferred embodiment of the present invention will be described.
A plate-like body according to an embodiment of the present invention is a translucent or semi-transparent window plate (hereinafter simply referred to as a transparent plate) having a front surface and a back surface facing each other across a thick portion. One or a plurality of light guides comprising a light incident end face for entering light, a light guide part for forming a predetermined path over the thick part, and a light emitting part for emitting the light. The member is embedded and configured as a aesthetic light-emitting element or a functional light-emitting element without protruding from any of the front surface, the back surface, and each side surface of the transparent plate-like body.

Here, even if a part of the light guide member is exposed or protrudes from the surface of the transparent plate-like body, the exposed or protruded portion is not an extraneous object that impairs the beauty, and is necessary for beauty or function. In such cases, such a transparent plate is within the scope of the present invention.
In the transparent plate-shaped body, the light incident end face of the light guide member is disposed at a part where external light is easily taken in, the light emitting part is disposed as a component of a predetermined characteristic part, and the light guide part is light incident. The length and the curve shape are determined along the position of the end face and the light emitting portion and the desired pattern.

  In the above configuration, the light incident on the light incident end surface from the front surface side or the back surface side of the transparent plate-like body is guided to the light guide portion, and the function of the transparent plate-like body (for example, the display function) ) Or functional light or impression light (design light) that enhances aesthetic appearance. Here, the light emitting portion is not limited to the end face from which light is emitted, but also includes a side surface that emits desired light (having a predetermined length) according to a demand for aesthetic functions. In this specification, among the portions of the transparent plate-like body, the portion where the light emitting portion is arranged or wired is also referred to as “predetermined characteristic portion” expressed on the transparent plate-like body.

The light incident on the light incident end surface from the front surface side or the back surface side of the transparent plate-shaped body includes, for example, natural light and illumination light from various illumination light sources including indoor illumination lamps, but is not limited thereto, for example, In addition, reflected light from a secondary light source such as a mirror body is also included. Also included is output light based on a control signal from a dedicated light source.
Also, depending on the aesthetic expression you want to realize, you can change the structure and arrangement of the light guide member, especially the light incident end face and light emitting part, so that, for example, the outline has a clear glow, Various shines (impression light, functional light) such as shine, dazzling shine, intensity or color changing shine, and undulating shine can be realized, and radiance can be diverged or gradation can be given gradation. .

  It is preferable that the light incident end face of the light guide member be arranged in the direction of arrival of external light as much as possible. Similarly, it is preferable that the light emitting end face is arranged toward the viewer side in consideration of the viewer's line of sight and viewing direction. In short, the directions of the light incident end face and the light exit end face can be arbitrarily set in principle. In general, since the direction of arrival of external light is different from the direction visually recognized by the viewer, in principle, the optical axis direction of the light incident end face of the light guide member does not match the optical axis direction of the light exit end face. If the light incident end face and the light exit end face of the light guide member are arranged as described above, the article color of the transparent plate-shaped body (stimulates the human retina by the light reflected and scattered from the surface of the received external light) Compared with the back transmitted light that enters from the back side of the transparent plate and enters the front side, the impression light or display light that is much brighter can be emitted from a predetermined characteristic part (light emitting part), so it is dim A predetermined characteristic portion provided on the transparent plate-like body can be shined both indoors and in a bright room.

  Here, if the transparent plate-like body and the light guide member are both transparent, the light guide member embedded in the transparent plate-like body cannot be easily distinguished from the transparent plate-like body. Will not be damaged. However, for example, the difference in refractive index between the transparent plate-shaped body and the light guide member is made as small as possible, the surface of the transparent plate-shaped body is made a frosted surface, an uneven surface, a lens surface, or a wave surface, or is colored or patterned. If the device is devised, the transparent aesthetics of the transparent plate-like body can be further enhanced. In this way, the isolated shine of the feature portion, which is different from the shine due to light reflection at the feature portion, causes a mysterious aesthetic to the viewer. The refractive index difference between the transparent plate-like body and the light guide member (core portion) is arbitrary, but is preferably set to 0.4 or less, and more preferably 0.2 or less. . Further, an antireflection film may be applied to the light guide member.

  Further, as a preferable light guide member, a step index type optical fiber or a graded index type optical fiber, or a side emission type optical fiber having one or a plurality of light emitting portions (light emitting side surfaces) on the side surface is used. It can mention, but it is not limited to these. For example, instead of a normal optical fiber consisting of a core part and a clad part, an optical fiber consisting only of a core part having a refractive index higher than that of the molded material may be used. Moreover, as long as it functions as an aesthetic light guide member, instead of the optical fiber, for example, a flat waveguide may be used, and a wave plate or various curved plate waveguides may be used.

  Examples of the material for the transparent plate-like body include, but are not limited to, known various glass materials and various plastic materials including low melting point glass and crystal glass. Similarly, as the light guide member (optical fiber), well-known various glass materials and various plastic materials can be preferably exemplified, but not limited thereto. Here, the combination of the material of the transparent plate-like body and the light guide member is not limited to the combination of the same quality materials, but may be the combination of different materials. However, in any combination, the light guide member has a high melting point or softening point (at least in the core portion) relative to the material of the transparent plate so that the light guide member does not melt and break in the molten transparent plate. It is preferable to use a guide member.

  Here, if a glass optical fiber is used as the light guide member, for example, an optical fiber having a thickness of 10 μm to 10 mm may be bundled in a predetermined cross-sectional shape to obtain a light emitting end face. A single line may be used. On the other hand, if a plastic optical fiber is used as the light guide member, for example, a single wire having a thickness of 50 μm to 20 mm can be preferably used, but if necessary, it is bundled into a predetermined cross-sectional shape. You can also In addition, in order to realize various aesthetic expressions, the light exit end face of the light guide member (optical fiber) is dotted, granular, true circular, semicircular, elliptical, semielliptical, rectangular, triangular, cylindrical, The shape may be a star shape or a three-month shape, and the shape may be irregular and disordered. Further, the cross-sectional shape of the light emitting end face and the cross-sectional shape of the light incident end face may be different.

Note that the core diameter may be reduced for a transparent plate-like body that wants to achieve fine or delicate shine as an impression point or a design point, or a transparent plate-like body that wants to realize a display point or identification point with high resolution. Of course, it is desirable. If a plurality of optical fibers are bundled, a large-diameter impression point, design point, display point, or identification point can be obtained.
The transparent plate-like body of the present invention can be suitably applied not only to a single-layer plate-like body but also to a laminated plate-like body and a multilayer plate-like body (for example, multilayer glass). Further, since the transparent plate-like body of the present invention includes a semi-transparent plate-like body, the frosted glass is also a transparent plate-like body. The transparent plate-like body is not limited to a flat plate-like body, and includes a curved plate-like body.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view showing a configuration of a window glass (transparent plate-like body) provided with an aesthetic light emitting element or functional light emitting element having a light guide structure according to a first embodiment of the present invention.
The window glass 77 of this example is schematically constituted by a transparent plate-like glass 78 and a plurality of side-emitting optical fibers 79 embedded in the plate-like glass 78. A plurality of optical fibers 79 are embedded in a thick portion of the plate-like glass 78 (without protruding from the front surface, back surface, and each side surface of the window glass) in a vegetation pattern that blows in the wind. In this example, the base end portion of the optical fiber 79 is focused on the lower end portion of the window glass 77 as a light receiving portion, and as shown in FIG. Are arranged side by side.

  In this example, since the side-emitting optical fiber 79 is used, external light Li such as room illumination light that has entered from the light incident end surface 79a is reflected from the side surface (light emitting portion) of the light guide portion 79b bent into an arcuate shape. ), The linear or scattered impression light (design light) Lo is emitted to the outside. Therefore, the window glass 77 displays a variety of linear beauty (vegetation that blows in the wind). On the other hand, if the light incident end face 79a is shielded, the external light Li is not incident, so that the vegetation scattered in the wind disappears and returns to the normal transparent window glass 77.

Next, when an LED illumination lamp or a desk lamp (not shown) is brought close to the row of light incident end faces 79a of the optical fiber 79, for example, as an external illumination light source, or when a spotlight is applied, these output lights Li are Since it enters from the light incident end face 79a and is emitted from the arcuate side surface while propagating through the light guide part 79b, the light guide part 79b looks as if it is shining like a plant stalk.
In addition, in order to prevent light from leaking to the outside, a light shielding sheet or the like is attached to the outdoor side of the window glass 77 on the side opposite to the indoor side to which the output light (external light Li) of the external illumination light source is applied. You may do it. Moreover, you may make it contact | abut or stick an LED chip board | substrate to the window glass surface corresponding to the arrangement | sequence site | part of the light-incidence part 79a. Note that if the plurality of light incident portions 79a and the LED elements are associated one-to-one and blinking is changed in time series, the vegetation appears to wind.

In this configuration, if the light emitting end surface 79c, which is the front end surface of the optical fiber 79, is also arranged so as to face the indoor side, for example, the front end portion of the plant (flower core, fruit or seed) appears to shine brightly. The beauty can be expressed with glass 77.
Further, if the optical fiber 79 of this embodiment is associated with various patterns and shapes, for example, in association with a print pattern or a cutting pattern by baking, it is embedded in the window glass 77 with excellent light decoration. Can be obtained.

  The number of optical fibers to be embedded can be increased or decreased as necessary. Of course, a plastic material may be used instead of the glass material if necessary. In addition, if the light incident end face 79a is arranged toward the outdoor side, natural light can be taken in, so that the impression light emitted from the light emitting part such as the light guide part 79b and the light emitting end face 79c of the optical fiber 79 is not generated. Because it changes in the morning and evening, you can enjoy the change of aesthetics according to the movement of the sun.

The window glass 77 of this example is made as follows.
First, each of the optical fibers 79 is preliminarily provided with, for example, a wind-curved curved shape by heat and pressure treatment, and then, among the constituent materials of the optical fiber 79, at least a temperature condition lower than the softening point of the core material. Below, an optical fiber 79 having a curved shape is embedded in the glass sheet in process, which is melted or softened, and then the glass sheet is cooled to complete the window glass 77. When embedding the optical fiber 79 in the molten or softened sheet glass, the optical fiber 79 is preheated to the temperature at the time of melting or softening the sheet glass or to the vicinity thereof. Is preferred. The above configuration and manufacturing method can also be applied to a transparent plate-like body such as a translucent or semi-translucent plastic. It should be noted that it is not easy to bend the light incident end face 79a (light emitting end face 79c) with respect to the guide portion 79b in a manner that fits in a thin transparent plate-like body. In order to overcome this, the curved region between the guide portion 79b and the light incident end surface 79a (light emitting end surface 79c) can be solved by making the diameter smaller than other linear regions. This is because it is relatively easy to bend the small-diameter region, and light does not interfere with propagation within the small-diameter optical fiber. As another solution, a method may be employed in which the thickness of the window glass (transparent plate-like body) 77 at the portion where the light incident end face 79c is arranged is made somewhat thick.

FIG. 2 is a diagram showing a configuration of a window glass (plate-like body) having an aesthetic light emitting element or a functional light emitting element having a light guide structure according to a second embodiment of the present invention, and FIG. FIG.
The window glass 80 of this example is functionally attached to the first and second main surfaces (front and back surfaces) opposed to each other, the thick part 81, and the thick part 81 as shown in FIG. And a plurality of optical fibers 82 embedded as elements or aesthetic light emitting elements. The optical fiber 82 is embedded in such a manner that the light guide portion 82b extends in the vertical direction along the front and back surfaces, and the incident end face 82a faces the surface or is flush with the surface, and the light emitting end face. 82c desires the front or back surface (FIG. (C), (d)), or desires the upper side surface in the figure ((b)), or is arranged in a manner flush with the front or back surface, respectively. Note that the light emitted from the light emitting end face 82c having the configuration shown in FIG. 5B is not used for the aesthetic formation of this example.

In this example, an optical fiber 82 that can output impression light with high luminance only from the light emitting end face 82c may be used. Instead of this, or in addition to this, linear impression light from a side surface having a length. A side-emitting optical fiber that can output the above may be used. If necessary, a side-emitting optical fiber that emits impression light only in a desired length region can be used, or a side-emitting optical fiber that emits impression light in a scattered manner at a predetermined interval. Can also be used. For example, if only the upper straight portion in FIG. 2A of the light guide portion 82b of the optical fiber 82 has a side radiation function, for example, a transparent window glass 80 as shown in FIG. A linear aurora LL can be expressed inside.
If the plurality of light incident portions 82a and the LED elements are associated one-to-one and blinking is changed in time series or in order by program control, the inside of the transparent window glass 80 A linear aurora LL that changes from moment to moment can be expressed (FIG. 3).

  As a means of associating the plurality of light incident portions 82a and the LED elements on a one-to-one basis, for example, as shown in FIG. 4, on the lower end portion of the window glass 80 where the incident end surfaces (light receiving surfaces) 82a of the optical fibers 82 are gathered. An example is a method in which an LED mounting portion 83 is provided, and the LED light source unit 84 is detachably attached to the LED mounting portion 83 with an adhesive tape or the like. When mounting by the sticking method, a positioning convex part (or concave part) is provided on the window glass (LED mounting part 83) side so that the row of each incident end face can receive LED light at a suitable position, It is preferable to provide a positioning concave portion (or convex portion) on the LED light source unit 84 side.

  Here, the LED light source unit 84 is desirably thin and light, and in a state where the LED light source unit 84 is attached to the LED mounting portion 83, each incident end face 82a, each LED of the LED light source unit 84, and However, it is comprised so that it may become the arrangement | positioning state which opposes one to one. In this way, each incident end face 82a is positioned at a suitable position where it can receive LED light. The LED light source unit 84 includes a detachable battery or a solar cell.

  The LED light source unit 84 may include one or a plurality of color LEDs or a full color LED set. Further, the combination of the incident end face (light receiving surface) of the optical fiber 82 and the LED may be one-to-one, M-to-one, or one-to-N (M and N are natural numbers of 2 or more). Further, the LED light source unit 84 includes an LED or a color LED set arranged corresponding to each optical fiber 82, and a drive circuit that dynamically controls light emission (flashing, color) of each LED or color LED set. If it is set as the structure provided, the impression light or display light radiate | emitted from the optical fiber 82 can be controlled dynamically. As this type of suitable drive circuit, a computer circuit with a built-in program that dynamically produces light emission under program control can be cited.

  In addition, the LED light source unit 84 or the LED mounting unit 83 includes a timer, and functions as a clock if the LED or the full color LED set is controlled to be turned on / off or changed in color based on an output signal from the timer. You can also That is, it is possible to realize a window clock in which a clock pattern of characters and patterns is embedded in the window glass. Further, due to the characteristics of the optical fiber described above, the impression light Lo can be configured to be emitted only to the indoor side and not to the outside of the room. Although the pattern can be seen, it can be configured so that it is not visible from the outdoor side and only a sense of transparency is felt. In addition, due to the above characteristics of the optical fiber, it is possible to display different characters and patterns to be displayed to those who are indoors and characters and patterns to be displayed to those who are outdoors.

  With such a circuit configuration, it is possible to produce a moving image in accordance with the music title and time. Further, if light is emitted only from the light emitting part at the tip of the optical fiber, dot display is possible, and not only images such as symbols and patterns but also character numerical value information can be displayed. In the above-described embodiment, the LED light source unit 84 and the LED mounting portion 83 are attached as means for mounting the LED light source unit 84 to the LED mounting portion 83. However, the present invention is not limited to this. Screwing, pinching or fitting may be used. The number of optical fibers 82 to be embedded is not limited to a plurality, and may be one.

Embedded as a aesthetic or aesthetic light emitting element. The optical fiber 86 is embedded in such a manner that the light guide portion 86b extends upward while undulating along the front and back surfaces. The incident end face 86a faces the surface or is flush with the surface, and the light exit end face 86c desires the front or back face, or is placed so as to be flush with the front or back face.

In this example, for example, if only the upper wavy line portion in FIG. 5A of the light guide portion 86b of the optical fiber 86 is provided with a side radiation function, for example, as shown in FIG. Aurora LL that undulates in the window glass 85 can be expressed.
In addition, if the row | line | column of several light-incidence end surface 86a and LED element are matched on a one-to-one basis, and blinking is changed in time series or in order by program control, a transparent window glass Aurora LC that undulates within 85 can be expressed (FIG. 6).
