DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light-emitting hard substrate which makes effective use of the light-emitting function of a transparent optical fiber having an outer surface as a light-emitting surface. It is suitable as.

[0002]

2. Description of the Related Art Conventionally, a transparent optical fiber having an outer surface (a surface in the longitudinal direction) as a light emitting surface is known, and the present inventors have used a nonwoven fabric mat or plastic cut out of characters or figures using this transparent optical fiber. A large number of the transparent optical fibers are arranged in parallel between the transparent vinyl chloride sheet and the base plate of the laminate made by sequentially laminating the tiles, the transparent vinyl chloride sheet and the base plate, and the cutout portion is colored or non-colored. Filling and curing a colored transparent methacrylic resin, and proposing a laminate having a light emitting decoration effect in which the converging end of each transparent optical fiber is made to correspond to a light source (Jpn.
No. 61496).

[0003]

However, in a laminate in which the transparent optical fiber having an outer surface as a light emitting surface is covered with a methacrylic resin, heating at about 80 ° C. or more is required to cure the methacrylic resin. Therefore, it is necessary to take measures to avoid the damage of the transparent optical fiber at the time of curing, so there is a problem that the production is troublesome, and when it is used on a road with a large frictional force, the cured methacrylic resin There was a problem that the layer was damaged and the light emitting decoration effect was lost.

Further, when a large number of transparent optical fibers are arranged in parallel and the outer surface is used as a light emitting surface,
There has been a problem that light brightness on the outer surface is low due to the straightness of light.

[0005]

SUMMARY OF THE INVENTION The present invention provides a transparent optical fiber which is hard to obtain a high brightness on the outer surface when it is linear.
Using at least three or more, those that were significantly improves light intensity of the outer surface by a string-like product of braid and string-like material disposed in the recessed groove formed on the surface of the rigid base The structure is such that its light emitting effect is not impaired even under severe use conditions by covering the upper part with a transparent ultraviolet curable resin.

That is, according to the present invention, in the groove 3 of the hard base 1 selected from a stone, a tile, a brick, a glass block, a hard plastic and a wood, on the surface of which the character or the pattern 2 is formed by the groove 3, transparent optical fiber 4 to a plurality of outer surfaces and the light emitting surface of the three knitting Misa the strands of material 40, string-like material 40 is a transparent composite state is inserted into the resin tube 8 or the cord-like material 40 It is arranged in a state where the transparent synthetic resin coating layer 8 ′ is provided on the surface,
Transparent ultraviolet curable resin 5 so as to cover the upper part of
And a hardened light emitting substrate, wherein the transparent optical fiber 4 has a converging end corresponding to the light source 10.

In practicing the present invention, it is desirable that each transparent optical fiber 4 be focused so that both end faces of the transparent optical fiber 4 correspond to the same light source, and the light source 10 be disposed at the focusing end.

In the present invention, if necessary, a large number of transparent glass beads 6 are scattered, or a plate-shaped or rod-shaped transparent glass 7 is fitted on the upper surface of the transparent ultraviolet curable resin 5 in the hard base of the above-described embodiment. Further, these glass beads 6 and glass 7 can be provided in combination.

Various means can be cited as means for exhibiting the light emitting decoration effect in the present invention.
When always giving a constant color, the light source 10 of a specific color is used.
When the light source 10 of a specific color is used, the transparent ultraviolet curable resin 5 filled in each groove 3 is colored with a dye, or the colors of the transparent glass beads 6 and the transparent glass 7 are selected. By doing so, various color effects can be obtained.

Further, when it is desired to change the color emitted from each part of each character or pattern 2, a plurality of transparent colored plates are provided concentrically between the converging end of each transparent optical fiber 4 and the light source 10. By interposing a rotating plate (not shown), a change in color can be enjoyed on the character or design 2.

[0011]

In the present invention, since the plurality of transparent optical fibers 4 arranged inside the groove 3 to form characters and patterns 2 are formed on the three knitting Misa is by strands of material 40, a transparent optical fiber The outer surface of 4 becomes wavy in an uneven shape, and the brightness of light emitted from the outer surface increases by about 50% or more compared to the conventional linear arrangement in parallel, and is clearly visible. Can be. Further, by making both end faces of the transparent optical fiber 4 correspond to the same light source, light circulates in the transparent optical fiber 4 endlessly, so that luminous efficiency is improved.

In the case where the transparent glass beads 6 are scattered, the light is irregularly reflected by the transparent glass beads, so that the transparent glass beads 6 can be seen in a glittering state. Even when the light enters, since the light is irregularly reflected by the rod-shaped transparent glass, it can be seen in a glittering state.

When the transparent ultraviolet curable resin 5 is colored with a dye, or when the transparent glass beads 6 and the transparent glass rod 7 are colored, the light emitted from the light source 10 is colored, and the color is sequentially changed. If it is changed, a luminous decorative effect rich in variety of colors can be obtained.

In the present invention, strands of material 40 a plurality of transparent optical fibers disposed inside the grooves 3 are three knitted Misa is harsh use because they are covered by a transparent UV curable resin 5 It will not be impaired under the conditions.

Further, the transparent glass beads 6 are formed on the uppermost layer of the groove 3.
In the case where the transparent glass 7 is provided, the transparent ultraviolet-curable resin 5 is protected by these components, so that the transparent ultraviolet-curable resin 5 is disposed inside even under severe operating conditions that cannot be tolerated by the hardness of the transparent ultraviolet-curable resin. The string 40 is not damaged.

Since the string-like material 40 is protected by the transparent synthetic resin tube 8 or the transparent synthetic resin coating layer 8 ', it is not damaged when the transparent ultraviolet curable resin 5 is cured.
