  Further, the second means is characterized in that the LED or EL element light source is disposed inside or outside the transparent peripheral side surface, and the outermost surface of the peripheral side surface has a light blocking function.

  The third means is characterized in that the decorative plate has a curved shape.

  The fourth means is characterized in that the LED or EL element light source is disposed on the end face of the decorative plate.

  Further, the fifth means has a light blocking plate attached to a conventional signboard, the back surface having a light reflecting layer inside, a display surface having a transparent plate having a light reflecting sheet inside, A decorative plate having a design such as a figure is disposed in parallel between the light blocking plate and the transparent plate via a space, and an LED or EL element light source is disposed on a peripheral side surface.

  The display device of the present invention uses a reflective sheet having a mirror effect, so that light is reflected inside the display device and light can be led out without waste, enabling clear display with a small number of light sources, light and thin display Equipment can be provided. In addition, decorations such as letters can be displayed three-dimensionally as if they were floating in the air.

It is an example of a display of an illumination type display fixture. It is AA sectional drawing. It is BB sectional drawing. It is a part of different arrangement | positioning sectional drawing of a LED light source, (a) is a case where it arrange | positions to the outer peripheral edge part of a decoration board, (b) is an outer surface of a surrounding side board. This is an example in which a display device is constructed on a conventional signboard. It is CC sectional drawing.

The present invention will be described below with reference to the drawings.
FIG. 1 is a representative embodiment of the present invention. The display device 1 is configured by a display plate 12 in which two display surfaces on the front and back surfaces are each bonded with a mirror mirror sheet that transmits a part of light inside the transparent plate. In addition, a decorative board on which characters and figures are drawn is arranged in parallel so as to be sandwiched between the front and back display boards 12. A light source such as an LED element is disposed on the transparent side plate 10. As a result, it becomes possible to display the characters and figures three-dimensionally as if they were floating in the air. In addition, although the display instrument of this embodiment is a hexahedral box shape, the shape of the display surface may be any of a circle, a polygon, and the like. At this time, the display board 12 which hits the back surface can be confirmed by reversing the decoration of the decoration board.

  FIG. 2 is a cross-sectional view taken along the line AA in FIG. A display plate 12 having a mirror mirror sheet 4 bonded to the inner surface of a transparent plate 2 made of acrylic resin or the like is arranged on the front and back display surfaces, and a decorative plate 8 on which characters and figures are drawn is placed at an intermediate position through the space 7. Installed. It is desirable that the distance between the decorative plate 8 and the display plate 12 is equal on both the front and back sides. A light source 6 such as an LED element or an LED tape in which the light source is arranged on a tape is arranged on a transparent side plate 10 made of acrylic resin or the like arranged on the upper and lower surfaces and the left and right side surfaces of the display device 1. FIG. 3 is a cross-sectional view taken along the line BB in FIG. Here, the LED tape 13 is used as a light source. The LED tape 13 is bonded to the inside of the transparent side plate 10. The positions to be bonded are basically on both sides of the decorative plate 8. Basically, it is arranged on all four surfaces of the upper and lower surfaces and the left and right side surfaces.

  Light from the LED tape 13, which is a light source, is reflected by the mirror mirror sheet 4, and even if the light source has a small light quantity, it is possible to shine the decoration drawn on the decorative board 8 cleanly without unevenness. 2 and 3, the LED tape 13 is disposed on the inner side of the transparent side plate 10, but may be disposed on the outer side. In addition, it is desirable to apply light-blocking sheets or paint on the outer surface of the transparent side plate when placed inside, and further to the outer surface when placed outside to suppress the external leakage of light. . Moreover, when installing the LED tape 13 as a light source in the outer side of the transparent side plate 10, it is desired to waterproof. The color of the light source is arbitrary, but a narrow light source such as an LED tape or an EL tube is used. In the case of the embodiment here, the use of the LED tape as the light source can be cut at an arbitrary length and bendable, so that the construction cost can be reduced. At this time, it is better that the light source LED tape is waterproofed. It is possible to use not only LEDs dedicated to 100V but also LEDs such as car parts. In this case, it can be used by using an inverter that converts a 12V power source into 100V.

  Note that the decorative plate 8 may not be planar. For example, by bending and bending, a decorated character or the like will appear more three-dimensional and deep. Further, the surface may be engraved by etching or the like, or a substance capable of reflecting light such as a fluorescent sheet may be adhered. A plurality of decorative plates 8 may be used.

  Fig.4 (a) shows a part of AA sectional drawing of FIG. 1 which shows different arrangement | positioning of an LED light source. A processed side plate 11 in which a light source 6 such as an LED tape can be installed on the end surface of a decorative plate 8 in which scratches or engravings are made on transparent plastic or glass is used. The decoration applied to the decorative board 8 is highlighted by the light from the light source 6. At this time, by applying the LED tape to the outer periphery of the decorative plate 8, a display device that is thinner and lighter than the light source arrangement of FIG. 3 can be manufactured. A groove is formed in the processed side plate 11 so that the light source 6 can be attached. The decorative plate 8 is a transparent plate with scratches or engravings such as etching. In this case, when the light from the light source 6 enters through the interior of the decorative plate 8, the decoration appears more three-dimensionally. FIG. 2B shows an example in which the light source 6 is installed on the outer surface of the processed side plate 11. In any case, it is desirable to provide the light blocking layer 15 on the outer surface of the processed side plate 11.

  FIG. 5 is an example of the display device 1 of the present invention using a conventional signboard 13. FIG. 6 is a cross-sectional view taken along the line CC. In order to construct the present invention, the transparent plate 2 is manufactured in the same size as the conventional signboard 13, and the light blocking plate 3 disposed on the back surface of the display device 1 draws the size of the groove of the conventional signboard 13. The same size as the signboard surface. The transparent side plate 10 is made of a transparent plate such as acrylic, and the light source 6 is installed outside the transparent side plate 10. In this way, the replacement when the light source is damaged can be performed in the same manner as a conventional signboard. In this case as well, it is desirable to provide the light blocking layer 15 on the outermost surface of the transparent side plate 10.

  In the case where the light blocking plate 3 is an object that does not transmit light, such as iron, aluminum, and tin, for example, the reflective material 5 is adhered to the surface. When the light blocking plate 3 is used, the reflecting material 5 is preferably a mirror mirror sheet that reflects light almost completely. In the case of a transparent plate, a reflective film such as an aluminum foil that reflects light almost completely may be adhered. The decorative plate 8 can be replaced by processing a part of the transparent side plate 10. The construction procedure produces an outer frame so as to cover the outside of the transparent side plate 10 of the display device 1. A rail 9 is installed inside the transparent side plate 10 so that the decorative plate 8 can be easily taken out. The rail 9 is constructed on the inner side of the transparent side plate 8, and the decorative plate 8 can be replaced accurately and appropriately.

  Although not shown in the figure, it is possible to construct two decorative plates 8 in the display device 1 described above. By constructing two decorative plates, it becomes more three-dimensional than the construction examples described so far, and it is possible to make the decoration stand out even more. The light source or LED tape in this construction is the same as the explanation of the construction so far, but when two decorative boards 8 are constructed, a space 7 is provided between the decorative boards 8. In this case, the display surface of the display device may be circular or polygonal as described above.

  The present invention can also be applied to table decorations, wall hangings, stand signs for restaurants, etc., or ceilings.
