2. Description of the Related Art Conventionally, electronic devices have been used for advertising boards and the like. As this lightning device, for example, a desired character or figure is formed by bending a neon tube or irradiating a billboard with light from a fluorescent lamp.

[0003]

By the way, in the case of the advertising board using the neon tube as described above, since the characters and figures are formed by bending the neon tube, small characters and delicate figures, etc. are formed. Is not possible, and it is impossible to integrally form one character or graphic even if the character or graphic becomes large in size, and there is a problem that only a very crude advertisement effect can be expected. In addition to the above problems, the advertising board using the neon tube consumes a large amount of energy, the gas in the neon tube has an adverse effect on the environment, it is bulky, the manufacturing time is long, and the expensive voltage transformer is used. There are a number of disadvantages such as having to use a large number of. On the other hand, the method of illuminating the advertising board with fluorescent light such as fluorescent lamps to enhance the advertising effect of the advertising board is too monotonous, and it does not feel visually beautiful. There was also the problem of not being able to bring about an effect.

However, it requires a lot of installation time and cost due to the arrangement and wiring of a large number of light emitting diodes, and if some of them are broken, it is difficult to repair them. There was a problem in terms of aesthetics as it had to be left alone as a defective advertising board. In addition to the above-mentioned light emitting diode, an advertising board using optical fibers capable of emitting various colors is also used, but it requires a lot of manufacturing time for arranging the optical fibers, which results in a large cost. Since this optical fiber is represented by a dot,
It is difficult to draw letters and figures, which are a collection of continuous dots, and there is a drawback that it cannot be used especially for large advertising boards.

The present invention has been made in view of the above circumstances, and has a completely new structure without using a conventional light emitting means such as a neon tube, a fluorescent lamp, and an optical fiber, and is complicated as an advertisement. An object of the present invention is to provide a lightning device capable of expressing characters and figures of various shapes in various colors and obtaining a high advertising effect.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. In the following, a case where the present embodiment is used as an advertising board will be described. FIG. 1 is a cross-sectional view, in which a plurality of transparent plastic plates 1 formed in the same quadrangular shape, for example, plastic plates 1 formed of an inexpensive acrylic resin plate, are stacked to form a plastic plate laminate 2 Is formed.

On the back surface, that is, the lower surface of the plastic plate 1, letters or figures as an arbitrary advertisement bill are reversed and engraved, and a light reflecting portion 3 for reflecting the light when receiving the light is formed. Has been done. Also, this plastic plate 1
The surface opposite to the light reflecting portion 3, that is, the upper surface, is thinly coated with a polymer substance, for example, a substance such as silicone by the plastic plate 1, and a part of the light transmitted through the plastic plate 1 is reflected. The coating layer 4 is formed.

This coating layer 4 is a plastic plate 1
It is a polymer material having a larger light refractive index, has high light reflectivity for reflecting light incident at a certain angle or more, and when light is irradiated from the light irradiation means 10 described later, an adjacent upper layer or It plays a role as a blocking film that blocks light from leaking to the lower plastic plate 1, so that the light from the light irradiating means 10 is concentrated on the light reflecting portion 3. That is, the coating layer 4 prevents the light irradiated in the plastic plate 1 from being dispersed to the outside and collects the light on the light reflecting portion 3, whereby the light reflecting portion 3 This makes it possible to display advertisements consisting of letters and figures more clearly and effectively.

On the other hand, reference numeral 6 in FIG. 1 is a support frame for accommodating and fixing the plastic plate laminate 2, and in this support frame 6, a light irradiation means 10 comprising a liquid crystal device is provided. There is. As shown in FIG. 2, the light irradiation means 10 includes a light source 11, a spectroscope 12 that disperses the light emitted from the light source 11 into blue light (B), red light (R), and green light (G). X (upper and lower in FIG. 2) -Y (horizontal in FIG. 2)
Three liquid crystal shutter panels 13 to 15 that have a large number of picture elements arranged in a direction and selectively transmit the blue light, the red light, and the green light respectively by these picture elements, and a liquid crystal shutter. Bending means 16 and 17 that bend and collect the blue light and the green light that have passed through the panels 13 and 15, respectively.
An output lens 18 for enlarging the condensed blue light, red light, and green light and then enlarging the mixture to a predetermined size;
And a guide lens 19 for guiding the light that has passed through to the side surface of the plastic plate laminate 2, and in each of the liquid crystal shutter panels 13 to 15 described above,
Light is selectively passed through the picture elements based on a command from the controller 20.

Then, in the light irradiating means 10 configured as described above, the picture element for transmitting the blue light, the red light and the green light is set to the liquid crystal shutter panels 13 to 15 by the command from the controller 20. For example, each plastic plate 1 can be irradiated with light of a different color, and
Even with the same plastic plate 1, if the colors to be irradiated are made different along the Y direction (horizontal direction), it is possible to display more various colors in the light reflecting section 3.

FIG. 3 is an example of a cross-sectional view of a plastic plate 1 on which an advertising draft is engraved. The plastic plate 1 is cut on the lower surface of the plastic plate 1 into a chevron shape, a curved surface shape, a low wavy shape, or the like. By doing so, the light reflecting portion 3 is formed, and the degree of light reflection differs according to the cutting shape of the light reflecting portion 3, and it is possible to produce various atmospheres depending on the cutting form. In addition, in the light reflecting portion 3, generally, a mountain shape (inverted V-shaped type, or a type in which a bent portion is directed upward) is often used.
In the case of cutting into a letter-shaped type or a type in which the bent portion is directed upward, the inclination angle (θ) of the boundary surface is preferably about 15 ° to 45 °. At this time, since the inclined cutting surface is in a semitransparent state, a part of the light is bent toward the outside (upward in the drawing) as shown in FIG. 3, and the rest of the light is made to go straight without being reflected.

The above-mentioned light irradiating means 10 is provided on each of the four side portions of the plastic plate laminated body 2 as shown in FIG. 5, and from each of these side portions toward the center of the plastic plate laminated body 2. Light is emitted so that even if the light from one light emitting means 10 is blocked by the other light reflecting means 3, the light reflecting means 3 emits light from the other three light emitting means 10. The light is surely irradiated by 10 and, as a result, the light reflection part 3 is not irradiated with the light, that is, the blind spot of the light does not occur.

FIG. 4 is an exploded perspective view of a plastic plate laminated body 2 in which characters and figures are engraved. Light is reflected on the lower surface of each plastic plate 1 constituting the plastic plate laminated body 2. A plurality of characters and figures forming the part 3 are dispersed and engraved, and these characters and figures are engraved on the plastic plate 1 so as to be opposite to the characters and figures when displayed. In this example, the English character "C
"OKE" and the shape of a seagull flying over the sea are engraved as an example. Therefore, when displaying the four alphabets "COKE", four are used for convenience. Further, the plastic plate 1 used at this time varies depending on characters and figures, but it is generally preferable that about 2 to 6 sheets are used.
