  In the patent documents and actual application documents shown in the background art, the drawn characters, pictures, or sculptures are lit by the LEDs, so that a conspicuous effect is recognized, but they are not satisfactory in terms of flat and impressive display.

  The present invention provides a display means capable of embossing three-dimensionally engraving parts such as characters and pictures formed on a transparent plate and displaying them in an impressive manner.

  The display device of the present invention includes a transparent plate having a sculptured portion on the back surface, a light source that irradiates from an end surface of the transparent plate, and a reflective plate provided on the back surface of the transparent plate, between the reflective plate and the back surface. This is characterized in that a gap is provided in the display to illuminate the light and display the display in three dimensions.

  Further, the display device of the present invention includes a transparent plate having a sculptured portion on the back surface, a light source that irradiates from an end surface of the transparent plate, and a reflective plate provided on the back surface of the transparent plate, the transparent light source facing the light source A light diffusing portion is provided on the end face of the plate, and the display device irradiates the light of the light source equally over the entire display portion so that it can be clearly seen.

  Further, the display device of the present invention has a transparent plate with an engraved portion on the back surface, a light source that irradiates from an end surface of the transparent plate, and a reflective plate provided on the back surface of the transparent plate, It is characterized in that it is formed with irregularities that reflect light, and the details of the display section are more vividly and three-dimensionally raised.

  Furthermore, the display device according to the present invention includes a transparent plate having a sculptured portion on the back surface, a light source irradiated from an end surface of the transparent plate, and a reflective plate provided on the back surface of the transparent plate. An end face reflecting plate is provided on the end face other than the end face on which the light source faces, and the entire display unit is illuminated with no directivity by effectively using the light source to enhance the effect as a uniform image.

  Since the gap is provided between the transparent plate and the reflecting plate of the structure of the present invention, the light drawn by the engraving portion is overlapped with the light reflected by the engraving portion and the light of the engraving portion reflected on the reflecting plate. And the figure looks three-dimensional, so an effective display can be obtained. In addition, since there is a gap between the engraving surface and the reflecting plate, the three-dimensional appearance looks different depending on the viewing angle, which makes the display more impressive. That is, it is possible to make it look like a shadow character.

  Since the light diffusing part is provided on the end face of the transparent plate, the light from the light source is diffused and the sculpture part is uniformly irradiated, so that the entire area of the sculpture part can be seen to emerge. Depending on the position of the light source and the position of the engraving unit, the end of the engraving unit may not be irradiated. However, in the present invention, since the light is diffused, the arrangement and directivity of the light source and the positional relationship of the engraving unit Need not be strictly constrained.

  When a character is drawn in the engraving unit, since the character is a combination of vertical and horizontal lines or diagonal lines, the direction of reflection with respect to the light from the light source is not constant. For this reason, if the surface of the engraving portion is smooth, it may be difficult to see a line having an angle that does not accurately reflect light in the viewing direction. In the present invention, since the unevenness is formed on the engraving surface, a line engraved at any angle reflects light and can be easily visually recognized.

  In the present invention, when the end face other than the end face on which the light source faces is covered with the reflector, the light from the light source is not transmitted in a direction not related to the display, so that it becomes brighter and the direction of light irradiation to the engraving portion is various. Therefore, it is possible to make it appear as an equal image regardless of the direction of the drawn line.

    Embodiments of the present invention will be described below with reference to the drawings.

  An embodiment when the present invention is applied to a nameplate will be described with reference to FIGS. The engraving part 4 which carved the character was provided in the back surface 1b of the transparent plate 1, and the light source 2 in the direction orthogonal to the back surface 1b is disposed in a positional relationship in which the engraving unit 4 is irradiated from the end surface 1c direction of the transparent plate 1 Is done. The end face 1c of the transparent plate 1 facing the light source 2 is provided with a diffusing portion 6 for diffusing the light of the light source 2 in each direction, and FIG. 1 shows an example in which the end face 1c is formed in a lens shape. A reflective plate 3 is provided with a gap 5 at the back surface position of the back surface 1b, and reflects light emitted from the back surface 1c in the direction of the front surface 1a. A cover portion 7 that does not allow light to leak to the outside is provided at a position surrounding the end surface 1c of the transparent plate 1 and the diffusion portion 6 so that the diffused light cannot be seen from the surface 1a direction.

  In the above example, the engraving portion 4 is provided on the back surface 1b, but it can also be provided on the front surface 1a. Now, the transparent plate 1 is attached to the flat surface of a house or a gate with a mounting screw 12 as a nameplate. The power source of the light source 2 is an optical display means that uses electric energy generated by the solar unit 9 and stored in the charging unit 13 built in the storage unit 8 and does not require wiring work.

Characters are dug into the engraving portion 4 of the transparent plate 1 and the engraving portion 4 is illuminated with the light source 2 attached to the cover portion 7. At this time, by providing the gap 5 between the transparent plate 1 and the reflecting plate 3, it can be seen three-dimensionally as shown in FIG.
The transparent plate 1 uses a transparent material such as transparent plastic (transparent or translucent plastic such as acrylic, polycarbonate, vinyl chloride) or glass. The transparent plate 1 can be used either solid or hollow. Moreover, you may put a transparent substance in a cavity. Water and other liquids can be placed inside. The light source 2 may be a general light bulb, a fluorescent lamp, or an LED.
The reflection plate 3 can be used as long as it captures images and characters. Glass mirrors, stainless steel, plates, etc. that are mirrored can be used.

  As shown in FIG. 2, characters, pictures, etc. of the engraving portion 4 are projected on the reflecting plate 3 by the gap 5 between the transparent plate 1 and the reflecting plate 3 and appear three-dimensional. This is due to the fact that the light exiting from the engraving unit 4 and the image of the light reflected by the reflector 3 appear double. Various effects can be expected depending on the angle at which the three-dimensional appearance is viewed. Further, when the light source 2 is colored, the three-dimensionality of the characters and the shadow character effect become more prominent. When the depth of engraving of the sculpture part 4 is increased, a 3D effect is further produced.

Here, as shown in FIG. 3, by providing the gap adjusting portion 10 so that the gap 5 can be varied, the optimum distance can be adjusted according to the size of the character, the depth of engraving, and the like. If the distance between the reflecting plate and the engraving surface can be adjusted, it is possible to select a preferable level of solid according to the shape and size of the characters and figures of the engraving portion shown on the reflecting plate. Further, if a liquid such as water or a transparent substance is sealed in the gap 5, effective display is possible.
About the distance of the space | gap 5, when the engraving of the sculpture part 4 is deep, it changes with a large character or a thick character. This distance is about 0.1 mm to 10 mm, but in the case of a general nameplate, the gap 5 is optimally about 50% to 200% of the depth of the engraving portion 4.

The thickness of the transparent plate 1 is 3 mm to 50 mm in a general nameplate, but varies depending on the size of the character. A thickness of about 10% to 200% of the character size is optimal.
Further, as shown in FIG. 1, the mounting screw 12 of the display board 1 can be easily removed, so that when it is removed, it can be changed into an emergency lamp.

  As the light source 2, an ordinary light bulb, a bean bulb, a fluorescent lamp, an organic EL, an LED, or the like can be used. The power source for illuminating the light source 2 may be a 100V commercial power source, a DC power source, a battery, or the like, but can also be taken from natural energy. For example, a solar battery can be used for the solar part 9 as shown in FIG. In this case, a charging unit 13 such as a capacitor or a diode is provided in the storage unit 8. In the case of outdoor use, the solar part 9, the cover part 7 and the storage part 8 are preferably waterproof or drip-proof structures. It is also desirable to have a dustproof structure.

  As shown in FIG. 1, the mounting screw 12 can be easily mounted on a wall or the like. If the cover part 7, the storage part 8, and the solar part 9 are structured so that they can be easily removed with screws or the like, the cover part 7, the storage part 8 and the solar part 9 are left with only the nameplate part left when the electrical system fails. It is possible to send it for repair. In this case, only the transparent plate 1 can be attached and the nameplate part can be left.

Another embodiment of the present invention is shown in FIG. It is important to diffusely reflect the light from the light source 2 because the side of the sculpture part 4 that is perpendicular to the light source 2 tends to shine but the parallel side is less shining. Therefore, as shown in FIG. 4, a diffuser 6 for irregularly reflecting light is provided between the light source 2 and the transparent plate 1 on the end surface of the transparent plate 1, and this diffuser 6 is either concave or convex. Good or both. The pattern may be rough or fine. The point is to provide the end face with a shape that diffusely reflects light.
As a result, it is possible to reliably irradiate light even on the engraved character located outside the position of the light source.
The diffusion unit 6 provided on the end face of the transparent plate 1 can be provided with a separately created component as the diffusion unit 6a. In terms of design, providing the cover portion 7 and covering the diffusing portion improves the appearance and is refreshing.
Of course, the light source 2 may directly aim at the engraving part without providing the diffusion part 6.

  Another embodiment of the present invention is shown in FIG. FIG. 5 shows the fine irregularities 12 of the engraving portion when characters and the like are engraved in the engraving portion 4. When digging letters, the engraved part is made uneven by engraving so that it is easy to shine with light. The unevenness is easy to make even when the edge of the engraving blade is appropriately roughened. In addition, even if sandblasting is applied, fine irregularities can be formed, which may be used.

As shown in FIG. 5, in order to improve the visibility from the front, the light source 2 may be easily reflected on the front, and the engraved portion of the engraving portion 4 may be engraved obliquely to be tapered. When the taper is provided, the light from the light source 2 travels in the traveling direction 14 so that visibility from the front is improved.
The cross-sectional shape of the character can be U-shaped, V-shaped, trapezoidal, semi-circular, semi-elliptical, etc.
In addition, embedding a fine reflector such as glass beads in the engraving unit 4 can enhance the three-dimensionality.
In this case, even if there is no light source 2, characters can be clearly recognized with a slight amount of light.
Further, even if a color is given to the engraving portion or a translucent colored plate is used for the transparent plate 1, it becomes easy to visually recognize.

When the end face 1d, end face 1e, and end face 1f around the reflector 1 are surrounded by the end reflector 11 as shown in FIG. It is possible to illuminate the light evenly without making it possible to create an equal image. By encircling the surroundings, the light that escapes to the outside can be used effectively, and it shines brighter. In addition, the mounting screw 12 is not visible from the lateral direction of the transparent plate 1, so that there is an effect of refreshing visually.
In some cases, the enclosing end surface is not limited to three directions, but may be any one of the end surface 1c, the end surface 1e, and the end surface 1f, or two directions of any combination.

  Examples other than the nameplate can also be used for company signs, store advertisements and displays, restaurant menus and advertisements, and the like.
