The present invention relates to a light display device, and to display various types of figures and characters in a color photosynthesized by light reflection, and is particularly invented to be applicable to billboards and decorative picture frames.

The lighting apparatus which is used a lot in the conventional advertisement board is comprised very simply.

That is, it was only to bend the neon board to display a desired letter shape or to illuminate the lighting device inside and outside the billboard.

However, in the case of a billboard using a neon board, the tube is bent and installed so that small characters or delicate figures cannot be represented. The energy consumption is high, the gas used in the neon device causes environmental problems, there is a disadvantage that the bulky, long production time, and expensive voltage transformer must be used a lot.

In addition, it is too monotonous to illuminate the surface of the billboard by installing a fluorescent lamp inside and outside the billboard so that it is difficult to obtain a desired advertisement effect and gives a visually messy feeling.

In order to solve such drawbacks, billboards have recently been generalized by arranging the light emitting diodes to obtain various advertisement effects through light emission control of the light emitting diodes. However, the installation time and the cost of arranging and wiring a large number of light emitting diodes are high. In case of disconnection, repair is inconvenient and is often left in a very ugly manner, causing the advertisement pollution.

In addition, billboards using optical fibers that can make delicate changes in various colors are used, but not only the arrangement of numerous optical fibers, but also a lot of production time and excessive costs, and the representation of the shapes in dots so that the continuity of shapes can be the same. Difficult to arrange the optical fiber has a disadvantage that can not be used in large billboards.

Recently, the advertisement board using the liquid crystal display panel has appeared, but the installation cost is too expensive, and the technical constraints on the size are too great to be generalized.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a light display device capable of changing colors without changing the size and complexity of figures and characters.

It is another object of the present invention to provide an advertisement device having a vivid color having a very simple and compact visual appearance with a very simple internal and external structure.

The present invention is a means for achieving the above object, the light reflecting portion formed by continuously engraving letters or figures on the back surface of the plate-shaped transparent plastic plate, and illuminating the illumination bulb from the side of the transparent plastic plate In the reflection light reflected and refracted by the light reflecting part to appear on the front of the transparent plastic plate, a plurality of the transparent plastic plate is laminated, a portion of the letters or figures engraved on the back of each of the transparent plastic plate A stacking member which is combined and stacked so as to be arranged in one completed word or sentence or completed figure; A coating layer formed by coating a polymer material having a refractive index greater than that of the plastic plate on the surfaces of the transparent plastic plates constituting the laminated member; A coloring portion to which a paint for selectively passing light of a specific color is selectively applied to all sides of each plastic plate forming the laminated member; Illumination in which at least one room is installed in each room separately partitioned by a plurality of partitions generally formed on a support frame for accommodating the stacking member, and a portion facing the side surface of the stacking member is composed of a condensing lens. With light bulbs; And a lighting control device for controlling the brightness and the lighting order of the lighting bulbs installed in each room. The lighting effect of the lighting bulbs can be changed by the photosynthetic color by the lighting control of the lighting bulbs. It is characteristic to make it.

Hereinafter, with reference to the accompanying drawings, an embodiment of the present invention will be described in detail.

1 is a cross-sectional view of the present invention is a transparent plastic plate 1 having a thin and large area, for example, a plurality of plastic plates (1) formed of an inexpensive and easily obtainable acrylic resin plate is stacked, such as advertising boards, decorative frames, etc. To form a laminated member (2) to play a role.

On the back surface, that is, the lower surface of the plastic plate 1, letters or figures as desired advertising text are engraved in the opposite shape, and the light reflecting portion 3 which reflects when the cut interface receives light is formed.

On at least one surface of the plastic plate 1, a coating layer 4 coated with a polymer material, for example, silicon is thinner than the plastic plate is formed. Since the coating layer 4 is a polymer material, since the refractive index of the light is high and the reflectivity of the light reflecting the light incident at a predetermined angle or higher is high, when the light is irradiated from the lighting bulb 5 to be described later, the light is moved to an adjacent plastic plate. It serves as a blocking film to block the leakage, so that the light is concentrated in the light reflecting portion (3) to have a more vivid color.

Reference numeral 6 is a support frame for receiving and fixing the laminated member 2, and a plurality of partitions 7 are integrally formed at regular intervals, and an end portion of the partition 7 is formed on the side surface of the laminated member 2. By contacting it, it is possible to have independent rooms 8 which are partitioned by partitions 7.

One or more lighting bulbs 5 are located in each of the rooms 8.

The lighting bulbs 5 irradiate light to the inside of the plate through the side portion of the plastic plate 1 and the part facing the side portion of the plastic plate 1 is formed of a convex lens 9 and the remaining portion is mercury. By applying such an impermeable material, the light is prevented from scattering to all sides of the lighting bulb 5 and the light is condensed by the convex lens 9, thereby increasing the concentration of light forward.

One of a variety of colors, for example red (R), green (G), yellow, on the side circumference of the plastic plate (1) facing each room (8) formed by the plurality of partitions (7) (I), blue (B), such as a light-transmissive paint is painted or a toothed portion 10 attached to a separate color plate having such a color is formed, the colored portion 10 is a plastic plate The passing color of light irradiated into (1) is determined.

FIG. 2 is a cross-sectional view of a plastic plate 1 in which an ad text is engraved, and shows that the plastic plate 1 is cut into a mountain, a curved shape, and a low wave shape to form a light reflection part 3. The degree of reflection of light is different according to the shape, so the atmosphere can be slightly different depending on the shape cut. Generally, the type of chamfer is used. ° ~ 45 ° is preferred, and the inclined surface is a semi-transparent state so that the light is reflected forward.

3 is a view showing the area of the light emitted from the light bulbs, each of the light bulbs (5) to send light only forward, so that only a portion of the plastic plate (1) will be revealed, but a plurality of bulbs on all four outer peripheral surface of the plate Because of their arrangement, no desert of light occurs.

4 is an exploded perspective view of the laminated member 2 in which letters and figures are engraved. The letters or figures are sculpted in opposite shapes by injecting a partial portion onto each plastic plate 1. I carved a seagull image, for example.

At this time, the number of plastic plates 1 to be used is preferably about 2 to 6 sheets according to letters or figures. In the embodiment of the present invention, since COKE is composed of four alphabets, four sheets are used for convenience. First, C is engraved on the first plate 11, which is the upper plastic plate, O is the second plate 12 at the position corresponding to the letter position, K and E are the third plate 13 and the fourth plate 14 In the same way, the figure is also carved into the arc, seagull and wave wave by separating the pieces into four plates, and then laminating the four plates. At this time, of course, characters and figures are carved into the opposite shape.

5 is a front view showing an embodiment of the present invention divided into four horizontal and horizontal sections of the plastic plate divided into four to each room and each side of the plastic plate 1 facing each room (8) specific The coloring part 10 or the color plate is attached to form the color part 10. For example, a green color plate G is attached to the first plate 11 where the A bulb is located, and the B bulb is attached. The red color plate R is attached to the second plate 12, and the yellow plate Y is attached to the third plate 13 on which the C bulb is located, and the fourth plate 14 on which the D bulb is located. The paint which lacks the blue coloring plate B or transmits the light of such a color is colored.

Each of the lighting bulbs 5 is connected to a lighting control device 15 that controls the lighting sequence, lighting time and brightness of the light, and operates according to the situation input to the lighting control device. According to the program, the lighting mode can be produced in various ways.

If all the A bulbs in each room are lit by the lighting controller 15, the light irradiated from each of the A bulbs passes through the green colored portion G of the first plate 11, and then is the boundary of the letter C. The green letter C is projected forward by hitting the reflector 3.

This phenomenon occurs because the boundary cut out from the plastic plate acts as an obstacle to the immediately before the light, so the light reflected from the A bulb passes through the green colored portion G and is formed by the letter C. This is because the letters are projected in the same color as the green colored part G by hitting the part and changing the direction of the light to proceed toward the laminated member.

On the other hand, if all the other B, C and D bulbs are lit at the same time, the letter C is green, the letter O is red, the letter K is yellow, and the letter E is blue, and each letter appears in a different color. When the reflecting unit 3 receives the light of a plurality of colors at the same time will have the color of the synthesized light.

That is, since light can express all colors by synthesis, depending on the color of the coloring part 10 and the lighting bulbs 5 which are colored on the side surface of the plastic plate 1 corresponding to each room 8. Characters and figures can be changed continuously in various colors over time.

In the above embodiment, a simple color is produced for the purpose of understanding the invention, but when configured as shown in FIG. 6, infinite color can be produced.

In FIG. 6, the side parts of all the plastic plates 1 are colored in different colors for each divided part, and at least one lighting bulb is installed in each room. When painting, it is possible to produce various colors such as color television images.

That is, the light of different colors irradiated from all sides of the plastic plate hits the light reflecting part of the character or figure, and then turns to the front of the plastic plate to produce the letters or figures of the synthesized color. If there are multiple lighting bulbs installed in the room, and the plastic plate and the lighting bulbs are all colored in different colors, the lighting combination of the plurality of lighting bulbs located in one room and the lighting combination of all the bulbs may not be described in detail. Colors can be revealed and all of this is possible only by the colored situation and lighting control of the lighting bulb.

Here, of course, it is not necessary to color all the parts, and when no specific part is painted, white light is irradiated, so that the brightness and the atmosphere can be adjusted by combining with light of different colors.

Referring to the effects of the present invention as described above are as follows.

Letters and figures are divided into parts on a plurality of prepared plastic plates, which are carved and stacked on different plates. When you look at the stacked boards from the front, you will appear to be carved into one complete letter and figure.

The lighting bulbs installed in each room are coated with an impervious substance of light on the side thereof, and the front side increases the light condensing and straightness of the light, thereby reducing the power consumption and increasing the clarity of the ad text.

If there is no piece inside the plastic plate through which light is projected, nothing is projected out and only the sculpted part appears outside. If the irradiated light is distributed to the outside through the adjacent plastic plate while advancing inside the plate, the ad text Although the sharpness of the film is remarkably degraded, the coating layer of the polymer material having a large refractive index prevents light from being diffused to the outside, so that light is concentrated on the light reflection part, and only the ad text is more clearly displayed to the outside. As such, the coating layer that prevents light dispersion is an important component that doubles the clarity that is the life of the advertisement together with the condenser lens of the lighting bulb.

The effects of the present invention as described above are listed in more detail as follows.

First, the present invention has a very high visual advertising effect because it can produce a variety of colors freely by photosynthesis only by controlling the lighting of the lighting bulb,

Secondly, since it is a simple laminated structure of transparent plastic sheeting, it does not cause visual pollution like conventional billboards.

Third, extremely delicate figures can be easily expressed on plastic sheet by computer engraver, which can produce various advertisements.

Fourth, because only ad texts such as letters or figures are revealed, power consumption is very low.

Fifth, since the installation space is small and there are no parts used to express characters or figures, the weight is light and the production cost is very low.

Sixth, because there is no part that can be broken, it has a long life and easy maintenance.

The present invention is not limited to the above embodiments, and various modifications possible from the inventions identified from the following claims are merely equivalents, and their uses may also be variously applied.
