Because of this, even in the case of a large signboard is an effect that is easy to manufacture the signboard.

In addition, almost all light rays incident to the inside of the transparent acrylic panel can be refracted and reflected by the V-shaped grooves formed on the rear surface thereof, as well as the protrusions formed on the transparent acrylic panel. There is an effect to increase.

Furthermore, by applying a sheet of reflective material to the V-shaped grooves on the rear side, the efficiency of light can be maximized by refracting and reflecting the rear light incident to the inside of the transparent acrylic panel and emitting to the rear side.

Hereinafter, with reference to the accompanying drawings will be described in detail the prefabricated transparent acrylic panel and LED lighting signage using the same according to an embodiment of the present invention.

First, a look at the prefabricated transparent acrylic panel according to an embodiment of the present invention.

FIG. 2 is a diagram illustrating a structure of a transparent acrylic panel according to an exemplary embodiment of the present invention, and FIGS. 3 to 6 are enlarged views of regions A, B, C, and D of FIG. 2.

As shown in Figure 2, the transparent acrylic panel 100 according to an embodiment of the present invention is provided with a square plate shape 110, to maximize the refraction and reflection of the light rays on the border surface of the plate shape 110 A plurality of protrusions 120 are formed adjacent to each other and integrally with the plate 110.

The transparent acrylic panel 100 according to the present embodiment may include at least one of methyl methacrylate (MMA) and polycarbonate.

The plurality of protrusions 120 has a thread structure in a triangular shape, and the vertices of the triangles (ie, the inner angle of the triangle pitch) have 90 degrees. The plurality of protrusions 120 are provided in the same size and shape.

The plurality of protrusions 120 preferably have a distance d between pitches of two triangles adjacent to each other about 5 mm to 15 mm. This can be determined as a range that can maximize the light transmission efficiency while the minimum space that is easy to place the LED chip for the lighting signboard between the two triangles. That is, since the size of the LED chip to be disposed between the two triangles is about 5mm, the distance (d) between the pitches of the two triangles should be larger than this. Since the transmission efficiency of the emitted light may be reduced, it is preferable to maintain a proper distance to maximize the efficiency.

The reason why the plurality of protrusions 120 are provided in the same size and shape is to make it possible to easily assemble two or more acrylic panels 100 when producing a signboard. That is, when assembling a plurality of acrylic panels 100 and applying them to a lighting signboard, it is not necessary to provide different types of acrylic panels, and if a plurality of only one type of acrylic panel is provided, the lighting signage is assembled by up, down, left and right assembly. Since it can be manufactured, it is easy to assemble, in particular to uniformize the parts to efficiently produce and production costs.

In addition, the four corners (A, B, C, D) of the plate 110 has a shape as follows in order to facilitate assembly.

As shown in an enlarged view of FIG. 3, the first corner A is formed at a corner of the first horizontal plane 110a perpendicular to each other and the first vertical plane 110d (hereinafter, referred to as a first corner A). Triangular protrusions 120a-1 and 120d-1 having the hypotenuses 110a and the first vertical plane 110d, respectively, are formed adjacent to each other at the ends of the first horizontal plane 110a and the first vertical plane 110d. . Thus, the outer edge of the first corner A is seen as a rectangular shape. The long side of the rectangle is the sum of the lengths of the two right sides.

As shown in FIG. 4, the second corner B is an edge formed by the first horizontal plane 110a and the second vertical plane 110b, and protrusions 120a-k are formed at the end of the first horizontal plane 110a. The second vertical plane 110b, which is formed and is perpendicular to the end of the first horizontal plane 110a, is formed by being dug by the protrusion 120b-1. Thus, the outer edges of the second corners B have a square shape. The sides of the square are half of the two right angles.

As enlarged in FIG. 5, the third corner C is a region that is origin symmetric with the first corner A, and has the same structure as the first corner A. FIG.

That is, each triangular protrusion 120b-k, 120c having the second vertical plane 110b and the second horizontal plane 110c as the hypotenuse at the corner formed by the second vertical plane 110b and the second horizontal plane 110c perpendicular to each other. -1) are formed adjacent to each other. Thus, the overall shape looks like a rectangular shape like the first edge A. FIG.

As shown in FIG. 6, the fourth corner D is an area that is originally symmetric with the second corner B, and has the same structure as the second corner B. As shown in FIG.

That is, the protrusion 120c-k is formed at the end of the second horizontal plane 110c and the protrusion 120d-k is formed at the end of the first vertical plane 110d perpendicular to the end of the second horizontal plane 110c. It has a square shape, formed by digging.

The plate 110 thus formed is cut as shown in FIGS. 7 and 8.

For reference, FIG. 7 is a cross-sectional view of the cut line ′ of FIG. 2. As illustrated, the transparent acrylic panel 100 has a plurality of V-shaped grooves 130 formed on the rear of the square plate 110. have.

The V-shaped groove 130 prevents back light by refracting and reflecting light rays incident into the transparent acrylic panel 100 and emitted to the back surface. Therefore, the efficiency of light is increased.

The V-shaped groove 130 is about the scratch (scratch), the degree of pitting is relatively small, the diameter and depth is usually about 1 to 2mm. This value may vary depending on the thickness of the transparent acrylic panel 100, for example, may correspond to a case where the thickness of the transparent acrylic panel 100 is 5 to 10 mm.

In addition, the V-shaped groove 130 may be spaced at regular intervals between the grooves adjacent to the upper, lower, left, and right, but is not limited to this, but may be spaced irregularly.

In addition, the V-shaped groove 130 is generally provided in the same size, but is not limited to this may be provided in various sizes. For example, the V-shaped groove 130 closer to the illumination source may have a smaller size, and may have a larger height and size of the V-shaped groove 130 toward the other side away from the illumination source. According to this structure, the efficiency of light may be further improved by refracting and reflecting all light rays incident from the illumination source and spreading far.

When formed in the V-shape, there is no blind spot that is not refracted and reflected when the light is incident into the groove, it can be more efficient than the structure formed by the square or semicircle.

In addition, as shown in FIG. 8, by additionally applying the sheet 140 of reflective material to the rear surface of the V-shaped groove 130, all the rays incident from the illumination source and emitted to the rear surface may be refracted and reflected. As a result, the back light may be reduced to maximize the light efficiency.

Therefore, the transparent acrylic panel 100 according to the embodiment of the present invention is formed with a rectangular triangular protrusion 120 on the edge of the plate 110, it is easy to assemble by fitting between a plurality of transparent acrylic panel, protrusion ( As well as 120, the light rays incident into the transparent acrylic panel 100 may be refracted and reflected by the V-shaped grooves 130 formed on the rear surface thereof. Thus, there is an advantage that the efficiency of the light can be increased even when assembled for a large signboard having a large size.
