The present invention relates to a signboard, and more particularly, to display advertisement contents having various colors and shapes to the outside by using light projected from a light source.

In general, a sign board using a light source mainly used at night is to install the light source inside the panel in which the advertisement contents are printed for mutual or other propaganda as is commonly seen in commercial areas, or to display the advertisement contents to the outside, or After mounting a number of light emitting devices on the panel, these devices are connected to each other in a circuit so that various types of advertisement contents stored in the program are displayed to the outside.

As an example of this kind, a display device as disclosed in Korean Utility Model Publication No. 93-4758 discloses a light source installed inside a triangular panel having a wing plate at each corner, such that the panel is rotated by wind power and at the same time. This is to be expressed outside.

However, in such a case, the advertising effect can be seen with a small installation cost, but it is limited by the size or installation according to the advertisement contents, and is produced by manual labor, so that mass production and advertisement contents cannot be changed. The problem is that it doesn't fit at all.

In addition, Korean Utility Model Publication No. 91-6624 or 91-8974 discloses a variety of advertisement contents through a display group consisting of a plurality of optical fiber bundles or a plurality of light emitting element groups connected in a circuit. Disclosed is to enable display. However, such a display device is not practically required because it does not meet many consumers because the manufacturing and assembly work of parts is very complicated and requires a separate energy source.

The present invention has been made in view of the above-described points, and can be adjusted in various colors and forms according to the contents of the advertisement, and can be used semi-permanently regardless of size or installation. The purpose is to provide a signboard that can easily replace the advertisement contents as needed.

A feature of the present invention for achieving this object is a transparent panel formed with a plurality of protrusions having a dot shape at the same interval on the front, rear and integrally, so as to prevent light from being transmitted between the protrusions on the transparent panel. The first and second blocking films, a color sheet attached to the rear surface of the second blocking film and having various inherent colors, and freely cutable, and a power supply is applied to the support frame in which the display media are assembled and assembled. A light source installed to provide light to the color sheet; Connection parts are formed at four ends of the transparent panel to be combined vertically and horizontally, and at least the length of the protrusion formed on the front surface is longer than the protrusion formed on the rear surface; The transparent panel is a sign board which is injection molded with acrylic resin or polycarbonate resin.

Hereinafter, a preferred embodiment of a sign board according to the present invention will be described in detail according to the accompanying drawings. 1 to 3 are diagrams for explaining the signboard of the present invention. In the rectangular flat transparent panel 10 constituting the signboard, a center distance L of about 7 to 10 mm on the front and rear surfaces thereof is shown. The protrusions 10a and 10b of the cylindrical body having a shape are arranged in a dot shape.

Connection portions 10c are formed at four edges of the transparent panel 10 so that the connecting portions 10c may be arranged in a row in a vertical direction. The protrusions 10a and 10b formed on the front surface of the transparent panel 10 may have diameters. This is about 5 ~ 6mm, the length is about 8 ~ 10mm, the protrusions (10a, 10b) formed on the back are the same diameter, but the length is formed about 0.1 ~ 0.3mm.

The transparent panel 10 is usually molded by an injection molding machine as an acrylic resin or a polycarbonate resin having excellent transmittance.

In addition, the first and second blocking films 11 and 12 having respective adhesive layers are attached to the front and rear surfaces of the transparent panel 10 to prevent light from being transmitted. In this case, the first and second blocking films 11 are provided. 12, insertion holes 11a and 12a are formed at positions corresponding to the protrusions 10a and 10b formed in the transparent panel 10 so that the first and second blocking films 11 and 12 may be formed in the protrusions 10a and 12b. Interposed between the 10b) is attached to the front, back of the transparent panel 10, the second blocking film 12 is attached to substantially match the end surfaces of the protrusions (10b) formed on the rear of the transparent panel (10).

The first and second blocking films 11 and 12 may preferably use a matte black sheet to completely block light transmission, and may be attached only to the front surface of the transparent panel 10, but the transparent panel 10 It is preferable to attach a double in between.

In the case of attaching the first and second blocking films 11 and 12 to the transparent panel 10, when the transparent panel 10 reaches the set position by using an automatic device such as an automatic inserter, the air ( It is possible to blow into the air and the like so that the insertion holes 11a and 12a of the first and second blocking films 11 and 12 are inserted between the protrusions 10a and 10b of the transparent panel 10.

On the other hand, the back of the second blocking film 12 is freely cut in various forms according to the advertising content, the color sheet 13 having its own color is attached to the projections 10a, 10b before the transparent panel 10 It can be displayed to the front through the screen.

The color sheet 13 is a vinyl chloride for color transmission (manufactured by 3M of the United States of America), which is commonly used for various purposes, and can be produced in a wide range of colors. It can also be replaced.

The display medium combined as described above is assembled and assembled in the supporting frame 14 as shown in FIGS. 2 and 3, and a light source (2) is applied to the rear of the display medium through a connector 15a. 15 may be installed to allow light to be transmitted to the color sheet 13 side of the display medium, and a reflection film 14a may be attached to an inner surface of the support frame 14 on one side of the light source 15 to further increase the internal illuminance. .

In the present invention configured as described above, the power is applied to the light source 15 in the support frame 14 containing the display medium, and the color sheet 13 in which the light projected from the light source 15 constitutes the display medium. Is delivered to.

At this time, since the color sheet 13 is already determined according to the advertisement content, the color of the color sheet 13 is transmitted through the protrusions 10a and 10b formed on the front and rear surfaces of the transparent panel 10 as they are. And, the protrusions (10a, 10b) of the remaining portion is the light of the light source 15 is transmitted as it is.

For example, assuming that the color sheet 13 is an English letter " Sign " as shown in FIG. 3, the text is displayed in a predetermined form, and other portions are not colored and light of the light source 15 As it is transmitted through, it is displayed on the rectangular flat plate with the letter "Sign" in the designated color.

In addition, the plurality of protrusions 10a formed on the front surface of the transparent panel 10 form a dot shape, but since the center distance L thereof is very dense as about 7 to 10 mm, it is continuously displayed when viewed from a long distance. Since the first and second blocking films 11 and 12 are attached to each other with the panel 10 interposed therebetween, the color of the color sheet 13 overlaps when passing through adjacent protrusions 10a and 10b. This prevents further increase in sharpness.

In addition, the first blocking layer 11 may prevent the fall of the focus by absorbing external light by using a matte black sheet, and may prevent the focus from falling. Of course, it is effective that the reflective film 14a blocks light projected from the light source 15 so that only the protrusions 10a and 10b of the transparent panel 10 are transmitted. 10c) can be used continuously arranged up and down and left and right regardless of the size.

In the above-described embodiment, a preferred embodiment of the present invention has been described, but the present invention may be easily deformed to the extent that the shapes of the transparent panel and the protrusions are possible.

According to the signboard according to the present invention as described above, by using the light projected from the light source to display the advertising content having a variety of colors and shapes to the outside through the dot-shaped protrusions formed on the transparent panel, the size or installation Regardless, it can be used semi-permanently, it can be mass-produced by automated equipment, and it can easily replace advertising contents.
