Abstract

PURPOSE:To obtain an effect which is excellent in display characteristic and visibility even if the background is bright or dark by forming white characters on the rear surface of a fluorescent material contg. resin plate and forming characters of a metallic tone on the front surface smaller than the characters on the rear surface, thereby increasing the brightness of light emission. CONSTITUTION:The rear side characters 12 consisting of a coating material or film having light reflectivity is formed on the rear surface of the transparent resin plate 11 formed of a resin into which the fluorescent material is incorporated and the front side characters 13 consisting of a coating material or film of the metallic tone are formed on the front surface to the shape slightly smaller than the shape of the rear side characters 12 and in superposition thereon. The stereoscopic characters having the excellent visibility are then displayed by the overlap of the rear side characters 12 displayed with the high brightness by receiving the light emitted from the transparent fluorescent resin plate and the front side characters 13 of the low brightness formed smaller than the rear side characters 12 if the background of the sign board is dark. The front side characters 13 are displayed in a slightly silhouette tone if the background of the signboard is bright. The characters having the display quality are thus displayed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a signboard using a fluorescent resin plate made of a transparent resin mixed with a fluorescent substance.

[0002]

2. Description of the Related Art As a conventional signboard of this type, there is a signboard as shown in FIG.

That is, in the conventional example shown in FIG. 1, a signboard character 2 having a reflective white color is formed on the back surface of a fluorescent resin plate 1 made of a transparent acrylic resin mixed with a fluorescent substance of an appropriate color.
It is a signboard with.

[0004]

Since this signboard leaves the parts other than the signboard character 2 as the cloth of the transparent fluorescent resin plate 1, for example, in the daytime reflected light, it becomes a signboard of good quality. Although visible, for example, at dusk, the viewer side of the signboard is darker than the opposite side and the opposite side (background) is the white wall 3, and the brightness of the white wall 3 and the brightness of the signboard character 2 are similar. If so, the entire surface of the signboard shines and visibility is very poor.

When the black wall 4 is arranged in place of the white wall 3, the fluorescent brightness of the acrylic resin plate 1 is due to the reflected light only from the surface of the acrylic resin plate 1, so that the acrylic resin Since the light-collecting ability of the plate 1 is halved and there is no sense of transparency, it looks like a normal signboard.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of such a conventional problem, in which white letters are formed on the back surface of a fluorescent substance mixed resin plate, and the surface of the resin plate is also formed. The metallic letters such as gold, silver, etc. are formed with letters that are slightly smaller than the back side to absorb outside light sufficiently to increase the emission brightness, and while the resin plate is transparent, depending on the lighting conditions. An object of the present invention is to provide a signboard that can solve the problem that the display disappears.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on the embodiments shown in the drawings.

First, the structure thereof will be described. Reference numeral 11 is a transparent fluorescent resin plate made of a resin in which a highly light-resistant fluorescent substance of an appropriate color is mixed in a transparent acrylic resin. Has a backside character 12 written in white paint or a white film. Further, on the surface of the fluorescent resin plate 11, a front side character 13 which is smaller than the shape of the back side character 12 and which is superposed on the signboard character 12 is applied by a paint or film having metallic luster. And constitutes the signboard 14.

The structure of this embodiment is as described above. Next, its operation will be described. In the signboard 14 having the above structure,
From the front and back sides of the transparent fluorescent resin plate 11 in the signboard,
When the outside light is incident, the reflection brightness of the back side character 12 is increased by the emission of the fluorescent dye. Therefore, the signboard 14,
That is, when there is no bright white wall on the back side of the transparent fluorescent resin plate 11 (when the background is dark), the back side characters 12 are displayed with excellent contrast to the background due to the high brightness of the back side characters 12 themselves. .

When a bright white wall is provided on the back side of the signboard 14 (when the background is bright), a metallic tone character 13 is superimposed on the front side of the back side character 12 which is reflected and displayed by the emission of the fluorescent dye. Since it looks like a silhouette, the back side letters 1
The peripheral edge (character outline) of 2 is reflected and displayed with high brightness. In other words, the front side characters 13 that are seen in a silhouette and the back side characters 12 that are reflected and displayed at high brightness are overlapped with each other, and the signboard characters are three-dimensionally and contourly displayed. It is a thing.

As described above, according to the signboard of this embodiment, when the background of the signboard 14 is dark, the backside characters 12 which are displayed with high brightness by receiving light emitted by the transparent fluorescent resin plate and have no translucency, and When the background character of the signboard is bright, the above-mentioned front character 13 is formed by overlapping with the front character 13 which is formed smaller than the back character 12 and has a low brightness. Since the sign is displayed in a slightly silhouette tone, it is possible to obtain a sign with excellent displayability and visibility regardless of whether the background of the sign 14 is bright or dark.

[0012]

As described above, according to the present invention, the back side characters 12 made of a highly light-reflecting paint or film are applied to the back surface of the transparent resin plate 11 formed of a resin mixed with a fluorescent substance, and the transparent resin plate is used. According to this, the sign 11 is formed to be slightly smaller than the shape of the back-side character 12 and is overlapped with the back-side character 12, and the front-side character 13 is applied with a metallic paint or film. When the background of the signboard 14 is dark, the backside characters 12 which are displayed with high brightness by receiving light emitted from the transparent fluorescent resin plate and the frontside characters which have no transmissive property and are formed smaller than the backside characters 12 and have low brightness By overlapping with 13, it is a three-dimensional display of characters with excellent visibility,
Also, when the background of the signboard is bright, the above-mentioned front side characters 13 are displayed in a slightly silhouette tone, so that the signboard 14
The effect that a signboard excellent in displayability and visibility can be obtained regardless of whether the background is bright or dark.
