Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a display 8 for displaying characters, figures, etc. on the surface of a non-transparent plate 6.
is engraved so as to penetrate through the back surface, and a light-transmitting board 7 is superimposed on the back surface of the non-light-transmitting board 6 to form the display board 2. The display board 2 is attached to the front opening of the box body 1, and the display board is formed. A light passing section 3 is provided in a portion extending from the front surface to the rear surface around the box body 1, and the light from a lighting fixture 5 arranged inside the box body 1 passes through the light passing section 3 and is irradiated onto the front surface of the display board 2. This invention relates to a lighting device, and its purpose is to provide a display board lighting device that can illuminate a display board regardless of the material of the display board surface, and that does not have the risk of the illumination affecting the surroundings. .

The invention will be explained in detail below using one example.

1 to 3 show a display board illumination device according to the present invention, in which a display 8 such as characters or figures is engraved on the surface of a non-transparent board 6 so as to penetrate through the back surface of the non-transparent board. A transparent plate 7 is superimposed on the back surface of the body 6 to form a display plate 2, and the display plate 2 is attached to the box 1.
A light passing section 3 is provided around the display board 2 from the front to the rear, and a light shielding reflector 4 is arranged around the outer periphery of the light passing section 3, which is arranged inside the box 1. It is shaped so that the light from the lighting fixture 5 is transmitted and reflected by the light passing section 3 and the light shielding reflection plate 4, and is irradiated onto the front surface of the display panel 2.

As the non-translucent plate 6, a plastic plate, an artificial stone plate,
Metal plates, wooden plates, etc. are used.

As the transparent plate 7, a glass plate, a plastic plate, etc. are used.

As shown in FIG. 3, the markings 8 are carved from the non-transparent plate 6 to the surface of the transparent plate 7.

In the figure, reference numeral 3 denotes a light passage section formed from a rod-like body, which is made of acrylic resin with good translucency, and has a fitting groove 20 on the bottom surface for fitting into the upper part of the display panel 2. is provided.

Furthermore, a light shielding reflector 4 made of an aluminum vapor-deposited film is provided on the upper surface and the peripheral surface of the side surface of the light-transmitting part 3 by vapor-depositing aluminum.

The rear part of the light shielding reflector 4 is an inwardly inclined surface 1 that slopes inwardly.
5, the light from the light source is allowed to enter, and the front part of the light reflector 4 has an outward inclined surface 16 that slopes downward to further reflect the light reflected from the inner inclined surface 15 to form a display panel 2.
It is designed so that the light is shining on it.

In addition, the rear lower surface of the light passage section 3 is an outwardly downwardly sloped surface so that the light from the light source enters the light passage section 3 perpendicularly, and the front lower surface is formed so that the light reflected from the outwardly inclined surface 16 is sloped downward. is an outwardly sloping downward surface that exits perpendicularly from the light passage section 3.

Reference numeral 5 denotes a lighting device, in which a tube 21 serving as a light source is provided in front of a lighting device body 22, and a reflecting plate 9 is provided between the lighting device body 22 and the tube 21.

Reference numeral 10 denotes a storage box, and the wall surface of the box 1 extends into the inside of the box 1 from the upper and lower ends of the front opening of the box 1, and is shaped in a concave shape. Place the upper and lower ends of storage box 1
0, and a lighting fixture 5 is attached.

The display board 2 is fitted with a light passage part 3 at its upper end and is covered with an adhesive tape 13.
After attaching the lower end to the recess 11 at the front lower part of the storage box 10, attach the light reflector 4 on the outer periphery of the light passage section 3 to the F-shaped mounting section 12 at the top of the storage box 10 using the adhesive tape 13. The display board 2 is fixed by covering the front opening of the box body 1 with a front board 14 having a notch in the center.

When the tube 21 is lit with the display board illumination device constructed as described above, a portion of the light emitted from the tube 21 passes through the light-transmitting plate 7 and the display 8 on the non-light-transmitting plate 2 The other part of the light oozes out in the same shape as the display 8, and some of the other light passes through the light passing section 3, is reflected by the light reflector 4, and travels as shown by the arrow in FIG. It is something that irradiates.

In the present invention, the light passing section 3 is shaped like a prism or made of acrylic resin that makes the refraction of light good, so that the light can be guided to the front of the display panel 2 well, but such a structure is not necessarily required. For example, the light passing section 3 may be made into a space and a light shielding reflection plate 4 that reflects the light may be provided as described above, or the light passing section 3 may be simply shaped into a prism 4 as mentioned above. The display panel 2 can be irradiated in the same way.

Conventionally, to illuminate a display board, the display board 2 was made of a translucent material such as milky white plastic or frosted glass, and light was irradiated onto the back surface of the display board 2, as shown in FIG.

Therefore, the light that passes through the semi-transparent display board is scattered and emitted in all directions, making it possible to see the characters on the display board, but the surrounding area is blinded and cannot be seen. It was limited and lacked a sense of luxury.

However, in the present invention, the light emitted from the lighting equipment oozes out onto the display on the non-light-transmitting board in the same shape as the display, making the display clearly bulge, and spreading over the area around the display board from the front to the rear. Since the light from the lighting equipment is irradiated onto the front of the display board through the provided light passage section, the display on the display board is always clear and reliable.Moreover, the display board is illuminated with indirect lighting, which is different from conventional methods. This has the advantage that all the light is not emitted from the display board, as in the case of the display board, and there is no risk of the display board being visible but the surroundings being blinded.

In addition, since the front surface of the display board is illuminated, the display board is not limited to semi-transparent materials as in the past, and is especially suitable for high-quality materials such as nameplates. In some cases, opaque materials such as marble, metal plates, and wood can be used to provide lighting.

Furthermore, since a display board is provided at the front opening of the box and lighting equipment is arranged inside the box, the lighting equipment can be completely hidden by the display board.
