First Embodiment
FIG. 1 shows a front view and a side view of a decorative wall material 1 according to a first embodiment of the present invention. 2 is a sectional view taken along the line AA of the decorative wall material 1 of FIG. 1, FIG. 3 is an enlarged view of a part of the relief 21 in FIG. 3, and FIG. Examples of circuits are shown respectively.

  In FIG. 1, a decorative wall material 1 is used as a wall member of a building, and includes a relief plate 11 and a lighting device 12.

  The relief plate 11 has a concave relief 21 formed by three-dimensionally engraving an image on the back side of a transparent plate having a rectangular front view. For a method of forming the relief 21, for example, Patent Document 3 described above can be referred to.

  The relief plate 11 is made of a synthetic resin such as transparent acrylic resin or polycarbonate resin, or glass, and has a size of, for example, about 200 cm long, 84 cm wide, and about 1 cm thick.

  In the example shown in FIG. 1, the relief 21 is obtained by engraving an abstract curve image on a plate of acrylic resin. However, the relief 21 is not limited to this, and is based on a photograph, an illustration, a picture, etc., using any natural objects such as plants or animals, natural landscapes, artefacts, artificial landscapes, people, or maps as drawing materials. You may form. Alternatively, the relief 21 may be formed based on an original image produced by computer graphics or animation.

  The illumination device 12 is provided in contact with the end face of the relief plate 11 and illuminates the relief 21 with the transparent portion of the relief plate 11 as a light guide plate.

  In FIG. 2, the relief 21 is engraved to a depth of up to about 50 to 90 percent of the thickness of the relief plate 11, and the engraved portion is a space KK. That is, the range of about 0 to 90 percent of the thickness of the relief plate 11 is a space KK by engraving.

  The engraving depth of the relief 21 may be changed depending on whether it is near the end or near the center of the relief plate 11.

  That is, for example, the relief 21 of a portion close to the end of the relief plate 11 and close to the lighting device 12 makes the engraving depth shallow (small), and the relief 21 of a portion close to the center of the relief plate 11 and far from the lighting device 12 Make the carving depth deeper (larger). In this way, appropriate illumination light also reaches the relief 21 in a portion near the center of the relief plate 11 and far from the illumination device 12, and necessary illumination is performed.

  In this case, as the engraving depth of the relief 21, an average of the engraving depth, a median of the engraving depth, or a maximum of the engraving depth may be used.

  The relief 21 is cut by, for example, a router using a router that performs cutting by rotating a cutting tool having a conical tip. As a result, the cut surface is in the form of ground glass (polished glass or polished glass). The frosted portion is a cloudy and opaque state or translucent state, and since the diffuse reflection of light occurs in this portion, the light transmittance is lower than that of the transparent case.

  In addition, by applying the solvent to a part of the cut surface, the applied surface is dissolved to reduce the surface roughness (smoothly), and a high transparency portion KT with improved transparency is formed. . The high transparency portion KT has high transparency to light because the cloudiness is eliminated and the transparency is increased.

  When applying the solvent (solvent), coating with a brush, spraying with a spray, or the like is performed. As the solvent, an organic solvent (organic solvent) such as thinner, alcohol or dichloromethane (methylene dichloride) or an adhesive is used. Also, instead of the application of the solvent, a fine cutting tool with a cutting edge may be rotated at high speed, or buffing (buffing) may be performed.

  The relief 21 includes a plurality of partial reliefs corresponding to a plurality of partial images, and for one partial relief (the outer relief 21a), the one is located closer to the center of the relief plate 11 than that. When there is another partial relief (inner relief 21b) in a relation in which the illumination light from the illumination light source 12 is blocked by the partial relief, the high transparency portion KT is formed for the one partial relief.

  The plurality of partial reliefs are formed such that, for at least a part of each, the illumination light from the illumination device 12 directly reaches or reaches via the high transparency portion KT.

  That is, the relief 21 in FIG. 1 includes an outer relief 21a provided in a frame shape in a portion close to the periphery, and an inner relief 21b provided separately inside the outer relief 21a. The light from the illumination device 12 directly reaches the outer relief 21a and sufficient illumination is performed. However, the light from the illumination device 12 is blocked by the outer relief 21a and sufficient illumination is performed in the inner relief 21b. It may not be Therefore, by setting the outer relief 21a as the high transparency portion KT, the light transmittance of that portion is increased, and sufficient illumination light reaches the inner relief 21b.

  The outer relief 21a shown in FIG. 3 is a high transparency portion KT, and a transparent pattern is visually recognized by illumination.

  As the plurality of partial reliefs, in addition to the frame-like outer relief 21a and the inner relief 21b shown in FIG. 1, a plurality of partial reliefs based on various independently arranged images, other partial reliefs, etc. It is also good.

  As shown in FIG. 4, the lighting device 12 comprises a flexible printed circuit board 31, a large number of light emitting diodes 32, and a frame member 33.

  The flexible printed circuit board 31 is in the form of a strip having substantially the same width as the thickness of the relief plate 11 and has a length surrounding the outer periphery of the end face of the relief plate 11. A lead wire is drawn out from the one end portion, and power is supplied via the lead wire. When the frame member 33 is made of a metal material, or when necessary, an insulating film is formed on the surface of the flexible printed board 31 opposite to the side on which the light emitting diode 32 is attached, or for insulation. The belt-like sheet of is pasted.

  The light emitting diodes 32 are white light emitting diodes, arranged in a line at a pitch of about 8 to 10 mm on the substrate 31 and attached to the flexible printed circuit board 31 by soldering or the like.

  The flexible printed circuit board 31 is disposed so as to surround the end face of the relief plate 11 in a state where the light emitting diode 32 is in contact with the end face of the relief plate 11. At this time, temporary bonding may be performed with a suitable adhesive or double-sided tape.

  When the light emitting diode 32 is turned on, the light emitted from the light emitting diode 32 enters the inside from the end face of the relief plate 11 and repeats reflection inside the relief plate 11 to reach the other end face. That is, the relief plate 11 functions as a light guide plate. The light incident on the relief plate 11 is irregularly reflected at the portion of the relief 21 in the middle thereof and is emitted from the surface of the relief plate 11. Thereby, the pattern of the relief 21 is viewed from the outside in a brightly illuminated state.

  The light propagating inside the relief plate 11 is diffusely reflected at the portion of the relief 21, so it is difficult to transmit the light farther than the relief 21. At this time, when the relief 21 is in a cloudy and translucent state, the light striking the cloudy relief 21 is hardly transmitted to a further distance. In this case, light is transmitted only by the portion of the thickness of the relief plate 11 where the relief 21 is not formed. Therefore, the outer relief 21a on the front side as viewed from the illumination device 12 is illuminated brightly, but if the outer relief 21a is cloudy, the light amount of the inner relief 21b on the far side which is shaded by it is Decreases and the lightness decreases. Therefore, by setting the outer relief 21a as the high transparency portion KT, the light quantity is maintained with an appropriate amount of light also for the inner relief 21b.

  When the outer relief 21a is a high transparency portion KT, the entire outer relief 21a may be a high transparency portion KT, or a part thereof may be a high transparency portion KT.

  The frame member 33 is a belt made of a metal material such as aluminum or stainless steel or a synthetic resin material and formed in a substantially U-shaped cross section, and surrounds the outer periphery of the flexible printed circuit 31 and is an end of the relief plate 11. It is attached so as to sandwich the edge.

  In addition, in order to fix the illuminating device 12 to the relief board 11, you may use a suitable screw member or a stop member.

  As shown in FIG. 4, in the lighting device 12, for example, a plurality of light emitting diodes 32 are connected in series, and a plurality of such serial connections are connected in parallel. Leads LA and LB are connected to both ends of each series connected body and connected to the power supply DG. The power supply device DG supplies a constant current to each light emitting diode, and operates as a constant current source for the light emitting diode. As the power supply device DG, it is possible to use a stabilized switching power supply, a battery, or the like.

  The connection method and number of the light emitting diodes 32 can be various other than this. Other DC power supplies may be used for the power supply device DG. In addition, the power supply device DG may be incorporated inside the decorative wall material 1. In this case, a cord and a plug for connection to a commercial power supply may be provided.

  Since the relief plate 11 is transparent, the decorative wall material 1 configured in this way is transparent because the relief plate 11 is transparent, and the portion of the relief 21 looks as a three-dimensional pattern. The portion without relief 21 is illuminated (illuminated) by the illumination device 12 because the illumination light is not emitted to the outside, but the portion with the relief 21 diffusely reflects the light by the relief 21. , The pattern of the relief 21 is visually recognized bright from the outside in the illuminated state.

  The decorative wall material 1 shown here can be used as a wall material to be attached to a wall surface, a ceiling surface, or a floor surface of a building. Moreover, it can use for a window or a door etc. by attaching a suitable attachment etc.

  Since the relief 21 is provided which is three-dimensionally illuminated by illumination, the decorative effect is high and it is suitable as a decorative wall material such as an interior. In addition, since indirect lighting is performed by the lighting device 12 around the decorative wall material 1, the decorative wall material 1 may be used as a lighting device for the entire room by arranging the decorative wall material 1 at an appropriate position of the room. It is possible.

Moreover, since the illuminating device 12 is provided in the outer periphery of the end surface of the relief board 11, thickness does not become large for the illuminating device 12, and it can be set as a structure strong in intensity.
Second Embodiment

  Similar to the first embodiment, the relief plate 11B is made of an acrylic resin or the like, and the size is about 180 cm long, 90 cm wide, and 1.2 cm thick.

  In the example shown in FIG. 5, the relief 22 consists of a plurality of partial reliefs 22a, b, c. Each of the partial reliefs 22a, 22b, 22c,... Is obtained by engraving an individual object on a plate of acrylic resin. As an object, for example, a rose flower, vegetables, birds, rocks, vehicles, clouds, celestial objects, abstracts, and other images may be used.

  The illumination device 12B is provided along the outer periphery of the end face of the relief plate 11B as in the first embodiment, and illuminates the partial reliefs 22a, 22b,.

  In FIG. 5, when viewed from the lower portion 12Bd of the illumination device 12B, the partial relief 22p is shaded by the partial relief 22p, so the partial relief 22p is a high transparency portion KT. Although the partial relief 22n is shaded by the partial reliefs 22d and m, an appropriate light quantity can be obtained by making the partial relief 22p a high transparency portion KT. However, the partial relief 22 d or the partial relief 22 m may be the high transparency portion KT.

  Further, when viewed from the right side portion 12Bb of the illumination device 12B, the partial relief 22f is shaded by the partial relief 22j, so the partial relief 22j is made the high transparency portion KT. Although the partial relief 22f is partly shaded by the partial relief 22b, an appropriate light quantity can be obtained by making the partial relief 22j a high transparency portion KT. However, the partial relief 22b may be the high transparency portion KT.

  The other portion of the partial relief 22 does not become a shade for the entire peripheral portions 12Ba to d of the illumination device 12B, so that an appropriate amount of light can be obtained without using the high transparency portion KT. However, other appropriate partial reliefs 22 or all partial reliefs 22 may be the high transparency portion KT.

As described above, by selectively setting any of the partial reliefs 22a, 22b, 22c,... As the high transparency portion KT, it is possible to adjust the lightness of each and enhance the decoration effect.
