[Problems to be solved by the device]

 However, the structure in which the mask plate that cuts out the display characters such as letters and pictures is attached to the back side has a complicated structure, and the display characters such as letters and pictures are attached to the outer surface of the translucent acrylic plate. Since what is printed by silk screen printing is illuminated by the illumination lamp from the back of the acrylic plate, if the luminance of the illumination lamp is increased, the area where letters are not printed becomes too bright, and if the luminance of the illumination lamp is decreased, the letters are printed. There was a problem that the part where the kind was printed had a shadow and became dark.

The present invention solves the above-mentioned conventional problems, makes the entire light-transmitting plate surface-emit, and provides a sufficient brightness difference between the background and the displayed characters, thereby making the displayed characters clear. It is an object of the present invention to provide an inside-illumination type display plate having an easily visible structure, an inside-illumination type illumination lamp using the same, and an inside-illumination type illumination device.

[Embodiment of the invention]

 Embodiments of an internally-illuminated display plate, an internally-illuminated illumination lamp using the same, and an internally-illuminated illumination device according to the present invention will be described below with reference to the drawings. FIG. 1 is a view showing the principle of light emission display of display characters on the internal lighting display plate of the present invention, and FIG. 2 is a front view of an example of the internal lighting display plate.

This internally illuminated display plate 1 includes a transparent plate 2 made of an acrylic plate or the like as a front plate, a mirror plate 3 as a back plate, an inner surface 2 a of the transparent plate 2, and a mirror plate 3. The upper and lower joint end surfaces are transparent to facilitate transmission of light. The upper and lower joint end surfaces are transparent so as to face each other and the outer surface 2b of the light-transmissive plate 2 faces outward. Is forming. The two plates 2 and 3 may be joined to each other using a transparent adhesive, but may be polymerized and fixed by other means such as screws, or may be held in a joined state by using a stopper. Here, the translucent plate 2 has a light diffusing surface 4 formed on its outer surface 2b, and display characters 5 such as characters and pictures are printed on the inner surface 2a by silk screen printing or the like. The mirror plate 3 has a mirror surface 6 formed by vapor-depositing aluminum or silver on the back surface of a highly transparent acrylic plate or a polycarbonate plate.

The translucent plate 2 may be transparent, but it may be formed into a fine uneven surface, a satin-finished surface, or a thin opalescent surface by etching treatment or application of a light-diffusing paint. Forming on the diffusion surface is preferably adopted in order to make the entire surface emit light uniformly. Further, when the light diffusing surface 4 is formed as in the latter case, even if dust or the like is mixed in from the gap between the translucent plate 2 and the mirror plate 3, the outer surface of the display plate 2 It does not show through, and it looks good on the product.

The mirror plate 3 is formed by vapor-depositing silver, aluminum or the like on the back surface 3b of highly transparent acrylic or polycarbonate to form the mirror surface 6, or by using a normal glass mirror plate as it is. Alternatively, a protective film 8 may be applied to the back surface of the mirror surface 6 in order to prevent the evaporated silver or aluminum from peeling off. FIG. 2 shows an example of the internally illuminated display plate 1. On the inner surface 2a of the translucent plate 2, a white character "TOILET" 5a is marked. Of the male and female pictures, the male picture 5b is blue, the female picture 5c is red, and the surrounding frame 5d is drawn. It is written in white. With this color coding, when normal white light enters from the upper and lower joint end surfaces 7 of the display plate 1, the character 5a of "TOILET" is white, the boy's picture 5b is blue, and the girl's picture 5c is The surrounding frame 5d glows red, and the surrounding frame 5d glows white. However, since the diffusion surface 4 of the translucent plate 2 and the display characters 5 have different degrees of light absorption, the display characters 5 are different from each other. Light that uniformly emits light in the surface is used as a background, and light with different brightness is emitted. Therefore, when the translucent plate 2 is viewed from the outside, the displayed characters 5 are clearly contrasted in the background that emits surface light.

According to the display plate 1 of the present invention, since it has a simple structure in which the translucent plate 2 and the mirror plate 3 are joined together, the display plate 1 is lightweight, and the manufacturing cost is also low. Further, the display characters 5 can be easily written on the inner surface 2a of the translucent plate 2 by silk screen printing or the like, and the structure is simple and the cost is low as compared with the cutout plate or the mask plate.

Further, as compared with the case where the translucent plate 2 is directly illuminated from the back surface by an illumination lamp, light is received from the upper and lower joint end faces 7 of the translucent plate 2 and the mirror plate 3 and reflected by the mirror plate 3. By illuminating the translucent plate 1 from the back side with uniform illumination, there is no feeling of lighting of the illuminating lamp, and neither too bright nor too dark. Therefore, only the display characters 5 are clearly displayed on the translucent plate 2, which gives a good impression and enhances the advertising effect.

Such an internally illuminated display plate 1 can be suitably used as a display plate for an internally illuminated lighting fixture, an internally illuminated display, or the like. FIG. 3 shows an internally-illuminated illumination lamp 10 using the internally-illuminated display plate 1 having the above-mentioned configuration. The internally-illuminated illumination lamp 10 has a box body 11 to which the internally-illuminated display plate 1 is attached. The structure is such that the illumination lamp 12 is housed in the body 11 almost directly above the internally illuminated display plate 1.

The internally illuminated display plate 1 can be suitably used as a curtain plate lighting device, a guide light, a toilet, an interior plate for guiding a telephone, a name plate, various display lights, and the like. 4 and 5 show an internal illumination type illumination device 20 using the internal illumination type display plate 1 having the above-mentioned configuration. The internal illumination type illumination device 20 is an internal illumination type in which display characters 5 are written on the inner surface. The display plate 1 is arranged on the surface of the box body 21, and as shown in FIG. 4, the illuminated surface portion 22 made of a louver, a milky white or a transparent plate is arranged at the bottom of the box body 21 to define the illumination range. . The illuminated surface portion 22 illuminates a purpose different from the display plate, for example, a game board or an operator's hand. In the illustrated example, the illumination lamps 23 housed in the upper and lower positions in the box body 21 illuminate the internally illuminated display plate 1 and the illumination lamps 23 in the lower position illuminate the illuminated surface portion 22. However, the irradiated surface portion 22 may be provided on the upper portion of the box body 21 or on both the upper and lower portions. Further, if the illuminated surface portion 22 is only on the lower side, one illumination lamp 23 is arranged only at the lower position so that the internally illuminated display plate 1 and the illuminated surface portion 22 on the lower side are illuminated. May be

FIG. 5 shows the overall structure of the internal lighting system 20. The internally illuminated display plate 1 having the display characters 5 on its inner surface is attached to the left and right ends of a box body 21 arranged on the front surface by attaching mounting frame plates 25, 25 to each other. The butterfly plates 26, 26 attached to the rear end portions of the upper surfaces of the plates 25, 25 are mounted in a suspended state by inserting screws into the support portions 27, and the lighting device 20 is supported by the butterfly plates 26, 26.
