Description

Advertising appratus using acrylic plate

The present invention relates to an advertisement apparatus, and more particularly, to a double-sided light emitting advertisement apparatus using an acrylic plate capable of double-sided advertising by emitting both sides with one light source using a transparent acrylic plate.

In general, a billboard that guides a place is used after the opaque color sheet or translucent color sheet, which is different from the acrylic panel, is applied to the surface of the acrylic panel. A lighting lamp was installed inside the box-shaped case, and a color sheet or translucent color sheet different from this panel was advertised on the surface of the translucent panel formed on the front of the case, and then attached and used. .

However, it is difficult to expect an advertising effect at night when the advertisement signboard which simply attaches the color sheet to the surface of the acrylic panel, and the advertisement signboard is displayed at night by displaying the color sheet attached to the surface of the signage by the illumination lamp mounted therein. On the other hand, while the degree of advertising effect can be expected, there is a problem in that during the day the illumination of the light is weak so that it is not possible to obtain an advertisement effect that can be understood.

In addition, advertising signs using neon signs are also used a lot, but also the effect of advertising in the daytime is insignificant, it is inevitable to burden the maintenance costs because a lot of power is consumed to operate the neon sign, moreover, if you change the advertising content neon The replacement of the entire signage adds to the cost of a new installation, which limits the advertising content.

Due to the above problems, an advertisement apparatus using a liquid crystal display panel has been developed. As a conventional example (application number 20-2004-2312), a segment electrode for displaying letters, numbers, etc. is formed in a known liquid crystal display panel. A polarizing plate and a reflecting plate are attached to the rear side of the liquid crystal display panel, and a polarizing plate having a different direction from that of the polarizing plate is attached to the front side of the liquid crystal display panel.

Therefore, when an electric field is applied to the electrode of the liquid crystal display panel, the segment electrode to which the electric field is applied is displayed differently from other parts, thereby displaying a letter, a number, or the like to perform a predetermined advertisement.

However, in the case of using such a liquid crystal display panel for advertising, a complicated process of designing and manufacturing a segment electrode suitable for a new advertisement text in order to change the text such as letters or numbers requires a cost in case of purchasing a small amount for advertisement. Not only is this very expensive, it is virtually impossible to carry out the design and manufacturing process for one liquid crystal display panel.

As another example of the prior art (application number 10-2001-63194), there is provided a bus route guidance display apparatus using an LCD backlight, and the above configuration is a bus route number guidance display board or a destination guidance display board mounted on the front and rear of the bus. It emits light for easy identification at night, and the light source is made to emit light using the LCD backlight as its light source so that the surface light is emitted at high brightness.

More specifically, as shown in FIG. 1, a case is fixed to one side of the front and rear of the bus and has a built-in protection case for the bus guide display panel, an LCD backlight fixed inside the case and including a fluorescent lamp and a reflector. And at least one light diffusion film on the LCD backlight, a guide panel on which the bus guide or advertisement is designed on the light diffusion film, and a fixing frame integrally fixing the LCD backlight, the light diffusion film and the guide display panel. It is composed.

As described above, when the fluorescent lamp used as a light source emits light to a desired portion by a reflecting plate and distributes light through a plurality of diffusion films, various devices are installed to emit light of advertisement text.

In addition, while having such a complicated structure, only one side can emit light. The basic reason is that the light emitted from the fluorescent lamp is not used directly, but using the reflecting plate. Therefore, in order to double-sided advertisement, the fluorescent lamps emitting in opposite directions must be installed, and the reflecting plate reflecting the light emitted from the fluorescent lamp. This is because each must be provided. However, when installed in this way, the volume of the billboard itself is inevitably increased and the manufacturing cost is inevitably increased.

The present invention is to solve the problems as described above, while reducing the volume (thickness) of the billboard, and can emit light on both sides with a single light source, acrylic plate that can be configured by stacking a thin acrylic plate The purpose is to provide a double-sided light emitting advertising device using.

1 illustrates an example of a conventional advertising device.

2 is an exploded perspective view of the advertising device according to the present invention.

3 is a partially enlarged perspective view of a fluorescent lamp according to the present invention.

4 is a combined perspective view of the advertising device according to the present invention.

The present invention is a transparent acrylic plate in which several grooves in a diagonal direction are regularly zigzag formed on the whole of one side in order to achieve the above object; Fluorescent lamps installed horizontally at upper and lower ends of the transparent acrylic plate; A lamp fixing member to which the fluorescent lamp is fixed; A power supply unit supplying power to the fluorescent lamp; It is connected between the power supply and the fluorescent lamp to provide a double-sided light-emitting advertising device using an acrylic plate comprising an inverter for controlling the voltage and current applied to the fluorescent lamp constantly.

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

As shown in Figures 2 to 4, the advertising device 200 according to the present invention is largely composed of acrylic plates (210a, 210b, 210c), the fluorescent lamp 220.

The acrylic plates 210a, 210b, and 210c are rectangular transparent acrylic plates having a purity of 95% or more, having a thickness of about 1 mm to 3 mm, and a plurality of grooves are regularly formed on one side in a diagonal direction. It has a width and depth of μm and the gap between the grooves is 100 μm to 2000 μm.

The acrylic plate is stacked several times, the direction of the grooves formed in each acrylic plate are formed to be opposite to each other to overlap when stacked.

The fluorescent lamps 220 are formed to have substantially the same length as the acrylic plates 210a, 210b, and 210c, and the two fluorescent lamps 220 are 3mm, which is approximately 1/2 the thickness of the stacked acrylic plates, and the two fluorescent lamps 220 are arranged in parallel up and down (c) It is fixed to the inside of the lamp-shaped mounting member 230. The fluorescent lamp may increase or decrease its number depending on the thickness of the acrylic plate. The length of the lamp mounting member 230 is formed to be slightly shorter than the length of the fluorescent lamp 120 so that both ends of the fluorescent lamp 220 is fixed to the lamp mounting member 230 when the fluorescent lamp 220 is fixed to the lamp mounting member 230 A predetermined amount protrudes to the outside of both ends of the 230 to facilitate the electrical connection with the inverter to be described later.

The bent portion 232 of the lamp mounting member 230 is a part that is fixed while wrapping the acrylic plate to apply an adhesive to the acrylic plate 220 or to form a hole and then fixed by fixing a screw or the like in the acrylic plate through the hole Let's do it.

A color film 260 having an arbitrary color is attached between the transparent acrylic plate and the fluorescent lamp, that is, the front surface of the fluorescent lamp so that light emitted from the fluorescent lamp can be transmitted and have any color. Color films 260 of different colors may be attached at predetermined intervals to emit light.

The outer circumference of the acrylic plate 210 holds the stacked acrylic plates 210a, 210b, and 210c, and fixing frames 252, 254, 256, and 258 are provided to support the top, bottom, left and right sides of the acrylic plate so that they can be easily fixed in the field installation. The end is glued or bolted to fix the acrylic plate and at the same time complete as a product. Both sides of the acrylic plate may be formed by engraving or embossing the desired advertising phrases or designs, and attaches the advertising papers (270) engraved with advertising phrases or patterns (content to be advertised).

An inverter 240 that controls the amount of current is electrically connected to one end of the fluorescent lamp 230, and the inverter 240 supplies stable power of 12V and 3A to the fluorescent lamp 220. Although the inverter 240 may be installed at one end of the acrylic plate 210, it is preferable that the inverter 240 is configured to be suspended in a fluorescent lamp and installed in the advertisement device installation structure at the advertisement device installation site.

Referring to the operation according to the above configuration is as follows.

When the power source is connected to the advertisement device, the reduced pressure through the adapter (not shown) passes the inverter 240 to stably apply the set voltage and current to the fluorescent lamp 220.

When power is applied to the fluorescent lamp 220, the light is irradiated toward the center of each acrylic plate at the upper and lower ends of the acrylic plates 210a, 210b and 210c, and the irradiated light repeats the diffraction and reflection and the acrylic plates 210a and 210b. The light transmitted through the side surface is reflected along the diagonal grooves 212 of the stacked acrylic plates, and is reflected to both sides of the stacked acrylic plates 210a, 210b, and 210c. Therefore, the advertising text or advertising paper of the embossed or negative electrode formed on both sides of the acrylic plate is surface-emitting.

Although the transparent acrylic plate has a large difference in light transmittance depending on the purity, even if the high purity acripan 210, the light emitted from one light source is dispersed when passing through the acrylic plate (210a, 210b, 210c) cross section There is a limit to reach to a certain distance, and when the grooves 212 in the diagonal direction are formed in the acrylic plate, the light is reflected along the diagonal grooves to reflect the surface light over a predetermined distance, and the acrylic plates are laminated, respectively. Since light is irradiated onto the acrylic plates 210a, 210b, and 210c, the surface of the acrylic plates 210a, 210b, and 210c may be high in brightness by mutual interference. In addition, high purity and thick acrylic plates are expensive due to manufacturing difficulties, but if they are formed by laminating grooves on a thin acrylic plate, they can be surface-emitted with high brightness even at low cost.

In the above, the fluorescent lamp may be installed on only one of the upper and lower ends of the acrylic plates 210a, 210b, and 210c to emit light on both sides of the acrylic plates 210a, 210b, and 210c. It is desirable for advertising purposes. And by connecting a plurality of acrylic plates and adjust the length of the fluorescent lamp according to it can easily manufacture an advertising device having a large billboard.

As described above, according to the present invention, both surfaces of the acrylic plate can be surface-emitted with a single light source, and the structure can be simplified since there is no need for a reflecting plate such as a diffusing film or a polarizing plate to the outside of the acrylic plate as before. The thickness of the film can be formed thinner than the existing one, and since the acrylic plate is used by laminating, it is possible to surface-emitting both surfaces with high brightness even with a thin acrylic plate having low cost.
