[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to "glazed finished product", "method for producing glazed finished product" and "display device using the glazed finished product". Products with membrane members attached,
The present invention relates to a manufacturing method thereof and a display device using the product.

2. Description of the Related Art Generally, a fluorescent substance emits fluorescent light in the visible light region when excited by excitation light such as ultraviolet light or ultraviolet light located on the short wavelength side of the visible light region. Due to the difference in composition, red in the visible light range,
It is specific to fluorescence emission of different colors such as orange, yellow, and green. Among the various colors obtained by this fluorescence emission, there is a color having a strong stimulating property, and therefore it is very effective if the color is used for a signboard or the like. That is, since the highly stimulable color obtained by fluorescence emission is a color that is appealing and does not exist as a color of ordinary printing ink or various paints, it is used as a signboard or as a fluorescence emission display device. It is used.

Contrary to the above, among the various colors obtained by fluorescence emission, there are colors that are less irritating and have a feeling of softness, and these colors are incandescent lamps. , It is difficult to create with an artificial light source such as a fluorescent lamp, and it creates a unique atmosphere. Therefore, a fluorescent lamp (black light) that emits ultraviolet rays by applying paint mixed with a fluorescent substance on the floor surface, wall surface, ceiling surface, etc. It is possible to irradiate the coating surface with excitation light from an excitation light source such as a fluorescent light emission.

As an example thereof, there is a fluorescent light emitting display device provided on the wall surface for displaying guidance such as a menu in a restaurant where the indoor illuminance is relatively low. This fluorescent light emission display device is provided with a display surface (for example, paper), uses a paint or the like mixed with a fluorescent substance to write characters or a pattern on the display surface, and a fluorescent lamp (black light) that emits ultraviolet light or the like. By irradiating the excitation light from the excitation light source, the desired characters and patterns are fluorescently emitted on the display surface.

Further, as a member to which a fluorescent light emitting film for fluorescently emitting a pattern or the like is attached, not a member such as paper which fulfills only the function of causing fluorescent light emission as described above, but the inner and outer wall surfaces of the building structure or the ceiling. The decorative function of fluorescent emission is additionally provided on the surface of the fired product, which is made of ceramics such as tiles used for floors and floors and has the original function of forming part of a building. The advent of concrete means by which it is possible is desired.

[0006]

Conventionally, there is no specific example of causing the surface of the fired product to emit fluorescence, and a coating material mixed with a fluorescent pigment is applied to the surface of the fired product to form a fluorescent light emitting film. However, it is conceivable to irradiate the fluorescent light emitting film with excitation light such as ultraviolet rays, but applying a coating material has low durability, and in particular, the surface of the baked product has poor wettability of the coating material. Due to its nature, strong adhesion could not be expected.

Further, the paint applied to the fired product is extremely deteriorated (or faded) with respect to ultraviolet rays and cannot be used for a long period of time. It cannot be a practical realization means because it cannot withstand environmental changes, that is, changes in the outside air temperature, environmental changes such as exposure to wind and rain, etc., and it significantly deteriorates due to the ultraviolet rays of the excitation light. Further, instead of applying the paint, it is possible to mix a fluorescent light-emitting material with an adhesive having weather resistance and attach it to the surface of the fired product. However, the hygroscopic property and the coefficient of thermal expansion of the adhesive have the fired product. However, it could not be a practical realization means for the reason that it is significantly different from the above, or that the ultraviolet rays of the excitation light cause a remarkable deterioration.

The present invention has been made in view of the above circumstances, and an object of the present invention is to sufficiently withstand environmental changes such as wind and rain, temperature changes, and deterioration due to excitation light to perform stable fluorescent light emission. It is an object of the present invention to provide a glazed finished product, a manufacturing method thereof and a display device using the same.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. First, a glazed finished product according to claim 1 of the present invention will be described. First,
FIG. 1 shows a glazed finished product according to the first embodiment of the present invention.
This will be described with reference to FIG. FIG. 1 is a perspective view showing a part of the glazed finished product in a cutaway manner. As a material of the glazed finished product 1, a fired product 2 made of tiles fixed to an outer wall surface, which is a kind of building structure, is used. It is used. This baked product 2
The plurality of sheets are attached to the core material at a predetermined interval and fixed by a fixing material such as mortar to form a predetermined outer wall surface.

On the upper surface of the fired product 2, the fired product 2
Has a glazed layer 3 formed by well-known means for protecting the surface of the outer wall surface and for giving a predetermined color and a predetermined texture for improving the appearance of the outer wall surface. . The surface of the already-glazed layer 3 has a uniform texture, and the already-glazed layer 4 is attached to the surface thereof in a predetermined shape, for example, an irregularly distributed shape. The already-glazed layer 4 is a fluorescent film member attached by heating a glazed raw material obtained by mixing a frit glaze with a fluorescent pigment that emits fluorescence by irradiating light from an excitation light source such as ultraviolet rays,
It shows a very pale color when it is not irradiated with excitation light, and gives a uniform texture of the already-glazed layer 3, in other words, a monotonous and mediocre texture. It gives a feeling.

When the color of the fluorescent light emitted from the already-glazed layer 4 is set to be a color having a strong stimulating property, the already-glazed layer 4 is irradiated with excitation light such as ultraviolet rays. Only the portion where 4 is formed emits fluorescent light, and the color is a color that is appealing as it does not exist as a color of ordinary printing inks or various paints, and is therefore extremely effective when used for a signboard or the like. That is, if the already-applied glaze layer 4 is formed so as to correspond to a predetermined character or shape, a signboard can be obtained in which the character or shape is made to emit fluorescence.

On the other hand, when the color of the fluorescent light emission in the already-glazed layer 4 is set to a color which is less stimulating and has a sensationally soft feeling, the already-glazed layer 4 is irradiated with excitation light such as ultraviolet rays. Only the part where the layer 4 is formed emits fluorescent light, and it is possible to create a unique atmosphere that is difficult to create with an artificial light source such as an incandescent lamp or a fluorescent lamp.
If the pattern is formed to correspond to a predetermined pattern, the pattern can be made to emit a fantastic fluorescent light.

Next, a glazed finished product according to the second embodiment of the present invention will be described with reference to FIG. This FIG.
It is a perspective view which fractures and shows a part of glaze finish product, and as the material of the glaze finish product 5, it is the same burned material 6 as the above-mentioned example, and the surface of this burned material 6 is as mentioned above. The already-applied glaze layer 3 (see FIG. 1) is not formed, and the already-applied glaze layer 7 similar to the already-applied glaze layer 4 (see FIG. 1) is formed directly on the surface of the fired product 6.

In this example, since the surface of the fired product 6 is not already formed with the glaze layer and the background of the fired product 6 is exposed, a wall surface having a rough texture can be formed. The surface of the already-applied glaze layer 7 can be caused to emit fluorescence by irradiating light from an excitation light source such as ultraviolet rays. Next, a method for manufacturing the above-described glazed finished product according to the first embodiment of the present invention will be described. That is, the manufacturing steps are as listed in the following items (A) to (D).

(A) Prior to attaching a glaze layer to a glaze finished product in which an already-glazed layer is formed on the surface of the fired product,
Make glazed raw material. This glaze material consists of a fluorescent pigment component consisting of a fluorescent pigment and frit glaze, a clay component, and a diluting liquid component.
It has fluidity by mixing the components. (B) The above-mentioned glazed raw material is applied to the surface of the product to be glazed, and the applied glazed raw material is dried. this is,
A product to be glazed and finished is preheated and the glazed raw material is applied to it, and the applied glazed raw material is dried by that preheating. The finished glazed raw material may be dried in a furnace or the like.

(C) The dried glazed raw material is fired in a high temperature furnace, and the fired material of the glazed raw material is attached to the surface of the finished product. (D) The glazed finished product to which the fired material of the glazed raw material is thus attached is cooled to be a finished product. The glazed finished product is obtained as described above.

On the other hand, the first specific example of the coating method in (B) is a glazed finish placed on a belt conveyor (not shown) running in the direction of arrow A at a predetermined speed as shown in FIG. When the jetting device 9 is installed above the product 8 and the glazed raw material C is jetted from the nozzle 10 of the jetting device 9 in the direction of the arrow B, the glazed raw material C is irregularly distributed on the surface of the glazed finished product 8. The glazed layer 11 is deposited. The diameter φ of the nozzle 10 at this time is 1 to 4 mm, preferably 2 mm.

When performing such coating, as in the case of (B) described above, the glazed finished product 8 is preheated and the glazed raw material C is sprayed to be applied, and the glazed finished product is preheated. The raw material C may be dried, or the glazed raw material C may be applied without preheating the glazed finished product 8, and then the applied glaze raw material C may be dried in a furnace or the like. The preheating temperature or the drying temperature is preferably 60 to 100 degrees.

In the second concrete example of the coating method in (B), as shown in FIG. 4, the mask plate 14 is brought into close contact with the already-applied glaze layer 13 attached to the upper surface of the fired product 12. 1 having a desired shape provided on the mask plate 14.
5, the same as the spraying device 9 shown in FIG. 3 or the glaze material C is applied through the opening 16 by the principle of silk screen printing to form the glazed layer 17 and the glazed layer 18 on the surface of the already-glazed layer 13. May be. The openings 15 and 16 at this time are not limited to the rectangular shape shown in the drawing, and may have any shape and may be characters, and can be set completely freely.

In the third specific example of the coating method in (B), two kinds of compositions of the fluorescent pigment contained in the glaze material for causing the fluorescent emission, that is, the first visible light color is fluorescent A first glazed raw material that emits light and a second glazed raw material that emits fluorescent light of a second visible light color are prepared, and the first glazed material 13 is formed on the surface of the already-applied glaze layer 13 on the upper surface of the baked product 12 as shown in FIG. Mask plate 1
The glazed raw material C is applied using the first glazed raw material through the opening 20 of 9 to form the glazed layer 17, and the second glazed raw material is applied through the opening 22 of the second mask plate 21 to apply the glaze. Layer 18
May be formed. This example is a case of two colors, but a plurality of glazed raw materials having more colors than this may be prepared and applied by using a spraying device or through a mask plate as in the above example. Good.

Next, an example of a display device constituted by using the glaze finished product according to the first or second embodiment of the present invention will be described with reference to FIG. This example
The glazed finished product according to the present invention is used for a tile constituting an outer wall of a building forming a part of a building structure. As shown in FIG. 6, the display surface 32 forming the display device 30 is formed by regularly arranging a large number of pre-baked products 31 which are divided into a plurality of rectangles. In this case, the lily flower pattern is divided and formed, that is, the fluorescent film member corresponding to the pattern is attached as a glaze layer to the surface of the burned material 31 by using the above-described manufacturing method.

In this example, the fluorescent film member has one type of fluorescent light emission color. By regularly arranging a large number of such burned materials 31, the outer wall is configured and the display surface 32 is configured. Below the display surface 32, there is provided a long shield plate having an L-shaped cross section that forms a building lighting member 33 having an inner surface as a reflection surface, and an ultraviolet ray is provided inside the bent portion. An excitation light source 34, which is an elongated fluorescent lamp that emits excitation light in a region, is provided along the longitudinal direction of the building lighting member 33.

Further, an elongated shielding plate having an L-shaped cross section which forms the building lighting member 35 is also provided above the display surface 32, and excitation light in the ultraviolet region is emitted inside the bent portion. An excitation light source 36 formed of a long fluorescent lamp is provided along the longitudinal direction of the building lighting member 33. The excitation light source 34 and the excitation light source 36 emit excitation light in the ultraviolet region, but a very small amount of visible light component is also emitted at the same time, and the light of this component directly enters the eyes of the observer. In order to significantly impair the function of the display device 30, the building lighting member 33 and the building lighting member 35 are provided, and have a function as so-called hidden lighting.

When the excitation light source 34 and the excitation light source 36 are turned on, the excitation light is applied to the display surface 32, and the light applied to the front side is blocked by the building lighting member 33 and the building lighting member 35. Avoid direct contact with the eyes of the observer. Therefore, the observer can visually observe the picture (lily flower) that is fluorescently emitted by the fluorescent light emitting film members formed on the surfaces of the many burned materials 31.

Further, since the fluorescent light emitting film member attached to the surface of the pre-baked material 31 is formed by firing, it is firmly attached integrally to the surface of the pre-baked material 31, so that deterioration such as peeling occurs. It has the same weather resistance as the burned material 31 and can withstand severe environmental changes, that is, environmental temperature changes, such as exposure to wind and rain, etc. No deterioration occurs, and it is possible to withstand long-term use equivalent to that of the outer wall component, that is, the burned material 31.

Since the display surface 32 is also used as the outer wall structure, the display surface 32 is irradiated with strong natural light such as the summer sun in some places. Therefore, the fluorescent light emission in this state occurs. However, since it is canceled by strong natural light and cannot perform its original function, the display device 30 is particularly effective at night when the illuminance is low. In addition, in this example, the display surface 32 is formed by the outer wall, but if the display surface is the inner wall, the display function by fluorescence emission can be operated all day long, and the display device 3 can be operated.
0 is particularly effective when used in a place with low illuminance.

In the display device 30 as described above, the intensity of the excitation light from the excitation light source 34 and the excitation light source 36 is not uniform over the entire display surface 32, and the upper portion and the lower portion thereof have high intensity, and the center of each of them is at the center. Since the intensity becomes gradually lower as it goes, the fluorescence emission intensity is not uniform over the entire display surface 32. However, although some unnatural feeling does not occur depending on the pattern to be formed, in a certain specific pattern, the unnatural feeling due to the decrease in the fluorescence emission intensity becomes remarkable. In such a case, as shown in FIG. 7, above the excitation light source 34, the intensity of the excitation light emitted from the excitation light source 34 with respect to the display surface 32 is substantially uniform over the entire area of the display surface 32. The light irradiation amount control member 37 may be provided to control so that

As a specific example of the light irradiation amount control member 37, a long plastic member arranged along the long excitation light source 34 is provided with a Fresnel lens function on the entire display surface 32. It suffices to irradiate the excitation light with a substantially uniform intensity. 7 shows the display surface 3
Although only the excitation light source 34 near the bottom of 2 is shown, the same applies to the excitation light source 36 side shown in FIG. As an example in which the intensity of the excitation light is made substantially uniform over the entire display surface 32, in addition to the example in which the light irradiation amount control member 37 is configured to have the lens function as described above, as shown in FIG. A light irradiation amount control member 38, which is a long member having a function of a reflecting plate, is provided below the excitation light source 34, and the display surface 3
It suffices to irradiate the entire surface of 2 with excitation light of substantially uniform intensity.

The display surface 32 is formed by using the light irradiation amount control member 37 shown in FIG. 7 and the light irradiation amount control member 38 shown in FIG.
Instead of irradiating the entire surface of the substrate with excitation light of substantially uniform intensity, the intensity of each fluorescent light emission of the burned material 31 on the display surface 32 is substantially uniform over the entire display surface. The emission intensity control means for controlling the intensity of the fluorescence emission of the film member, that is, the thickness of the fluorescence film is gradually increased toward the center of the display surface 32, and the intensity of the fluorescence emission is spread over the entire surface of the display surface 32. You may make it substantially uniform.

On the other hand, the excitation light irradiation of the fluorescent light emitting film member by the excitation light source is made substantially uniform as described above, and conversely, the intensity of fluorescent light emission by the fluorescent light emitting film member is made substantially uniform, and in addition, it is decorative. In order to obtain such an effect, an excitation light irradiation site selecting means may be provided to control so that the excitation light from the excitation light source selectively irradiates a part of the display surface. As a specific example of the excitation light irradiation site selecting means, a light source for irradiating the display surface with excitation light is a movable type, and an irradiation area by the light source is, for example, a circular area, and the circular area is selectively moved to display the excitation light. By causing a part of the surface to fluoresce and moving the region to fluoresce, it is possible to perform a display with extremely high appeal.
