Description

  The present invention relates to a sculpture display device using light such as arts and crafts.

  In general, arts and crafts such as paintings and painting plates, or wall decorations such as ancient sculptures are based on the reflection of light. Arts and crafts are based on the direct or indirect use of transmitted light.

  For this reason, it is said that, apart from the color tone, the latter is more visible and has a higher sense of reality than the same work thickness, which can be said to be a feature.

  Similarly, in the field of moving image reproduction, a liquid crystal TV using transmitted light or a CRT or plasma TV using self-emission is more realistic than a front projection TV using reflected light on a screen. It is easy to obtain. However, on the other hand, it is difficult to obtain a black color such as darkness, which has the disadvantage that it limits the sense of reality.

  Therefore, video technology that uses transmitted light and self-light emission and enables black reproduction that symbolizes sufficient darkness is an important means to enhance the sense of reality. Is currently eagerly desired.

  It is already known that red light or other transmitted light can be obtained by irradiating the back of a very thin wooden board. In recent years, nameplates, lamp umbrellas, character display boards for digital clocks, and the like using this are commercially available as healing products.

  These healing products are derived from the fact that, in addition to the natural texture of wood, sunset colors that have a very high affinity with humans can appear due to the wavelength selectivity of the transmitted light of wood.

As a prior art, as a nameplate with a lighting device, “an illumination portion can be waterproofed properly and a separate nameplate portion is assembled in a form protruding to the outer surface side of the front surface of the illumination portion”. A box-like box that can be installed at a desired location of a structure such as a gate pillar is formed, and a printed circuit board and a storage battery in which a light-emitting diode is assembled are incorporated therein, and the cover of the box facing the light-emitting diode is translucent. Dispersion plate is provided, and an illumination part is formed by providing a nameplate assembling part on the outer surface side thereof, and the nameplate assembling part is provided with translucency such as an acrylic plate and can be engraved A nameplate base material made of material and a natural wood board, stone board, artificial marble board, etc. suitable for the nameplate, or a synthetic resin material board laminated with a sculptureable decoration material printed or painted with a pattern suitable for the nameplate The nameplate part that is glued The characters from the side of the decorative material Les carved in the middle to reach a depth of nameplate preform attached. Invention is disclosed that "(e.g., see Patent Document 1.).

  However, these known technologies have a fixed (constant) thickness of the light-transmitting plate material, so that the light intensity of a single light, a single color, is simply a clear light, which is essentially the same as conventional products using cloth, paper, or plastic thin plate. It is based on the principle, and is therefore almost limited to character display applications and simple lighting.

  The present invention has been made in view of the above situation, and an object of the present invention is to provide a sculpture display device that uses transmitted light to enhance a sense of reality and a three-dimensional effect, and is excellent in appreciation.

  This invention can solve the said subject by providing the following structure.

  (1) The thickness of the range in which the light of the plate material cut out parallel to the upward growth direction of the tree is transmitted is set to 7 mm or less, and the surface of the engraving base material and the both surfaces of the back surface or at least one surface thereof An image that is engraved and has one or more light sources at a desired distance from one surface, which allows light of an arbitrary wavelength to be transmitted through it, and an optical pattern added to the surface of the base material opposite to the light source Engraving display device that can express.

  (2) The engraving base material having a thickness of 15 mm or less for transmitting the light of the plate material cut out at right angles to the upward growth direction of the tree is formed on both or at least one of the front and back surfaces of the engraving base material. An image that is engraved and has one or more light sources at a desired distance from one surface, which allows light of an arbitrary wavelength to be transmitted through it, and an optical pattern added to the surface of the base material opposite to the light source Engraving display device that can express.

  (3) The engraving display device according to (1) or (2), wherein the engraving base material is formed into a curved body and the convex side is the surface.

  (4) The engraving display device according to (1) or (2), wherein the engraving base material is formed into a cylindrical body and the outer peripheral side is the surface.

  According to the present invention, it is possible to provide a sculpture display device that has a high degree of freedom in artistic expression by combining a sculptured base material that has been sculpted and transmitted light, and that is excellent in appreciation.

  Hereinafter, embodiments of the engraving display device according to the present invention will be described.

  1 is an explanatory diagram in the first embodiment, FIG. 2 is an explanatory diagram in the second embodiment, FIG. 3 is an explanatory diagram in the third embodiment, FIG. 4 is an explanatory diagram in the fourth embodiment, and FIG. FIG. 6 is a graph showing the light transmission characteristics of the wood board, FIG. 7 is a graph showing the human visual sensitivity characteristics, and FIG. 8 is a photograph 1 (before lighting), FIG. 9 is a photograph 2 showing an example of the effect of using transmitted light on the engraving screen (when FIG. 8 is turned on), FIG. 10 is a photograph 3 showing an example of the engraving screen (before lighting), and FIG. It is the photograph 4 (when FIG. 10 is lighted) which shows an example of the effect of using transmitted light.

  First, the gist of the present invention will be described. When light is irradiated onto a wooden board, the light entering the wooden board attenuates exponentially with respect to the depth direction, and this attenuation coefficient (also called a light absorption coefficient) It has wavelength dependence, and the longer the wavelength, the less the light attenuation. Although it varies depending on the wood, a thin plate having a thickness of a certain unit or less in mm unit sufficiently transmits visible light. This means that the amount of transmitted light can be increased or decreased exponentially if the thickness of the wood board that is the base material for engraving is cut linearly, and the color tone is not only a single red color but also green and even a blue component. It can be predicted theoretically. Furthermore, a further problem is whether or not it is possible to reproduce the design within the mechanical strength holding range of the wood board and within the easy processing range, and to see with enhanced gradation so that it can be compared to paintings, etc. This was an unknown area.

The present invention focuses on the synergistic effect of human visual sensitivity having logarithmic sensitivity characteristics and the light transmission characteristics of the wood. In the same woody sculpture base material, the visibility K is relative to the wood board thickness d of the sculpture base material.
K = A (exp α) exp (β / d)..., A, α, β have a constant relationship, and the pattern can be recognized especially in the visibility saturation region where the amount of transmitted light is strong and in the range below this saturation region. It was experimentally found that sufficient gradation was obtained, and this was proved.

  It has also been demonstrated that subtle color modulation occurs effectively at the same time, and the darkness of black can be expressed sufficiently if the ambient light is suppressed. Viewing with enhanced realism and three-dimensionality is possible, and it is possible to display something that has never been raised from the darkness (see FIGS. 9 and 11).

  That is, it is unprecedented to satisfy the above-mentioned relational expression and express the sense of reality and the three-dimensional effect by finely adjusting the visibility K and the thickness d of the sculpture base material, which is a feature of the engraving display device according to the present invention. Yes, the principle source of the claims.

  FIG. 6 is a graph showing the light transmission characteristics of a wood board. In the drawing, when the thicknesses d1, d2, and d3 of the wood board increase (become larger) from the back irradiation surface on the right side to the viewing surface on the left side. , The transmitted light attenuates exponentially, and decreases with an exponential curve as the thickness of the wooden board increases from the normalized light intensity 1, from 820 nm red light to 620 nm green light, 450 nm blue light. It shows a state where the attenuation of the transmitted light amount shifts from small to large in order. That is, the longer the wavelength, the harder it is to attenuate, and the shorter the wavelength, the easier it is to attenuate.

  In other words, when the engraving depth is increased and the thickness d of the base material wooden board is decreased, the amount of transmitted light increases exponentially, and only red transmitted light, green light, and further blue light can be mixed.

  FIG. 7 is a graph showing the human visual sensitivity characteristics, showing that the visual sensitivity rapidly increases to the upper right with a slight increase in brightness from the dark region. The possible gradation range and the displayable gradation range in the present invention are conceptually indicated by straight lines with double-ended arrows in the drawing.

  Hereinafter, Example 1 is demonstrated with reference to FIG. 1 (a), (b).

  In FIG. 1 (a), the thicknesses d1 and d2 in the range through which the light of a sculpture base material 2 created from a plate material 1 or a checkerboard pattern 1 cut out parallel to the upward growth direction of the tree T is 7 mm or less. The engraving base materials 2a and 2b are engraved on the front surface 3 (3a and 3b) of the engraving base material 2 (2a and 2b), and one or more light sources are located at a desired distance from the back surface 4 (4a and 4b). 5, and the light source 5 transmits light of an arbitrary wavelength from the back surface 4 (4a, 4b) and transmits the image by adding a light pattern to the engraved surface (engraved surface) 3 (3a, 3b). Engraving display device De that can be expressed.

  In the case of Example 1, there is a strong tendency for the densely grown annual rings to overlap due to the plate or grid, so in consideration of the light transmittance, in this example, the average plate thickness in the desired range of the engraved surface d1 and d2 were 7 mm or less. As shown in FIG. 1A, in consideration of the sculpture pattern and the effect of transmitted light, the plate or grid pattern is freely selected and determined in both the vertical and horizontal directions.

  FIG.1 (b) is principal part structure sectional drawing of the engraving display apparatus De.

  Reference numeral 5 a denotes a support base for supporting the light source 5, 5 b denotes a light source code, 6 denotes a frame for the engraving display device De, and RE denotes visible light emitted from the light source 5.

  A second embodiment will be described below with reference to FIG.

  Example 2 is a sculpture base material 20 having a thickness d3 of 15 mm or less in a range through which light of the sculpture base material 20 created from the plate material 10 having a horizontal pattern cut out at right angles to the upward growth direction of the tree T, The surface 30 of the engraving base material 20 is engraved, and one or more light sources 5 are provided at a position separated from the back surface 40 by a desired distance. A sculpture display device De that can express an image in which a light pattern is added to the applied surface 30.

  In the case of Example 2, as compared with the case of Example 1, there is a tendency that the amount of transmitted light increases due to the decrease in the light absorption coefficient due to the anisotropy of the wood tissue, and that there are many parts where light easily passes through the annual rings. Therefore, the average plate thickness d3 in the desired range of the surface to be engraved is set to 15 mm or less, as compared with the case of Example 1. The configuration of the main part of the engraving display device De is the same as in the case of the first embodiment, and a description thereof will be omitted.

  In Example 3, the engraving base materials 2a, 2b, and 20 comprising the plate material 1 or the plate material 10 of the horizontal pattern and the plate material 10 of the horizontal pattern used in Examples 1 and 2 are formed into curved bodies as shown in FIG. And it is an example of the engraving display apparatus which has the convex side as the surface.

  In Example 4, the engraving base materials 2a, 2b, and 20 formed of the plate material 1 or the cross-patterned plate material 1 and the horizontal-patterned plate material 10 used in Examples 1 and 2 are respectively formed into a cylindrical body as shown in FIG. And it is an example of the engraving display apparatus which made the outer peripheral side the surface.

  Hereinafter, a sculpture photograph of the example will be displayed and described.

  FIG. 8 is a photograph of an example of a sculpture, in which a state of “Yokohama Port” is cut and engraved, and shows a state before the light source is incorporated (not lit).

  FIG. 9 shows the state of the ship and the building in the background that are visible through the light (lighted) from the back of the sculpture of FIG. 8 and appear in the dark.

  Compared with the case where the engraving surface is viewed with reflected light of external light (environmental light), when the external light is blocked and the transmitted light is used for viewing, it is shown that the sense of reality and stereoscopic effect can be greatly enhanced.

  FIG. 10 is a photograph of an example of a sculpture, in which the figure of “Nio” is cut and engraved, and shows the state before the light source is installed (not lit).

  FIG. 11 shows a state in which light is transmitted (lighted) from the back of the engraving object in FIG. 10 and appears in the dark.

  It should be noted that by engraving on both sides of the base material, it is also possible to realize a tasteful viewing surface with a light source transmitted from one side.

[Other Examples]
The other embodiment is an example in which two or more engraved base materials are combined at an arbitrary angle as shown in FIG. 5, and in the case of FIG. the Aitonaru sculpture angles phi _1, a case in combination with phi _2, engraving the number, combination angle phi _1, phi ₂ may be selected freely, and the position of the light source 5 in the center as shown in FIG. 5 It may not be necessary, and can be determined in consideration of the effect of transmitted light.

  Further, the engraving object engraved on the engraving base material can be configured to be rotatable around the light source 5.

  Moreover, it is good also as a structure which affixes the paper (especially Japanese paper is preferable) for reinforcement on at least one surface of the both sides of the sculptured wooden board.

  Moreover, it is good also as a structure formed by sticking the flame-retardant resin or glass for fire prevention to at least one surface of the both sides of the sculptured wooden board.

  In addition, a so-called “red cut filter” that blocks long-wavelength light longer than 750 nm is added to all or part of at least one of the front and back surfaces of the sculptured wooden board, and the green component is enhanced in the transmitted light color tone It is also good.

  In addition, a filter that blocks long-wavelength light having a wavelength longer than 600 nm is provided on all or a part of at least one of the front and back surfaces of the sculptured wooden board, and the blue color tone is partially or partially enhanced in the transmitted light color tone. Also good.

  In addition, a configuration having a mechanism capable of modulating (fluctuating) irradiation from a light source in time, space, or intensity, or a configuration in which two or more types of modulation are combined may be employed.

  Further, a system configuration in which music equipment such as a music box is combined with the engraving display device of the present invention may be adopted.

  Further, the engraving base material may be composed of a pulp raw material, a resin raw material, and a glass material.

  It should be noted that, as an art and craft, any design is possible as well as a picture including a hanging shaft, and it becomes a wall hanging and shelf placing product. In a display device in which the engraved wooden board is attached to one or both sides of a wall thickness of about 10 cm and a back light source such as a fluorescent lamp or a light-emitting diode is inserted therein, it is particularly useful to use this as a mural. Furthermore, ceiling murals embedded in the ceiling are also highly effective in creating healing spaces as products that also serve as indirect lighting.

  For crafts, the display device is incorporated into the back of the music box lid, and the product is a product that doubles the healing effect of a compact light source switch synchronized with the opening and closing of the lid.

  In addition, for example, in the case of figurines such as Kamakura and Nikko, the sculpture plates and other objects are not limited to being transparent, but can be painted with varnishes such as mahogany, etc. If it is applied to the product, it becomes a product with a favorite color tone.

  As an illumination or decorative article, it is particularly effective to use it for an indoor or outdoor fluorescent lamp, an umbrella for an incandescent lamp, an umbrella for a stand lamp, etc. in that the light source can be shared among the inventive devices.

  In addition, application to nameplates with symbols, billboards for advertisements, and illuminations is an effective product group for beautification of the town.

  As furniture and architectural products, for example, tempered glass or the like can be mounted on the side of the ornamental surface of the apparatus, and this can be used horizontally for a table, desk, or kotatsu top plate. In addition, attachment of the engraving display device to the front door or back plate of the sideboard or the display shelf can add added value that is not found in existing products.

  As the building supplies, all are useful, such as a space, a shoji, a bag replacement, a room partition, a door, and the like. Furthermore, if it is used as a substitute for stained glass, it will be warm, it will have a high affinity with surrounding building materials, and it will be a product that has the characteristics that it cannot be seen from the outside.

  In addition, for example, when used as a Buddhist altar or a godshelf, it is excellent as a soothing soul because the effect of revealing the remains is unparalleled. Regardless of sect or religion, it will be accepted by young people.

  In addition, the “sculpture processing method” is as follows: (1) Fleas, engraving swords, electric engraving swords, while irradiating the back side of the surface to be engraved with a normal fluorescent lamp, etc. (2) In machining using a cutting machine, the amount of transmitted light is measured with a light detector, and the depth of machining is displayed on a monitor (CRT). (3) In optical cutting using the laser sublimation method, there is also a method of feeding back the detected transmitted light amount and cutting and engraving according to the pre-programmed pattern shading. If information such as a digital photograph is input to a computer and cutting is performed in accordance with this information, it is possible to automatically manufacture a product having a feeling of tightness exceeding that of a photographic image.

  In this embodiment, a single light source has been described. However, the number of light sources is not limited, and any number of light sources can be freely selected and installed.
