The third transparent plate 400 is to prevent the first transparent plate 100 from being contaminated or damaged, and may be made of a material such as tempered glass.

The opaque plate 500 is disposed in parallel with the second transparent plate 200 in the third direction (z direction) so as to sandwich the second transparent plate 200 together with the first transparent plate 100. That is, the opaque plate 500 is disposed on the rear surface of the second transparent plate 200. The opaque plate 500 is made of an opaque acrylic material or other opaque plastic material. Accordingly, the opaque plate 500 hides the foreground of the rear of the second transparent plate 200 from being visible from the front of the first transparent plate 100.

The frame 300 is disposed side by side in the third direction (z direction) of the first transparent plate 100 side by side, 102, 104, side by side in the third direction (z direction) of the second transparent plate 200. The side surfaces 202 and 204, the side surfaces disposed side by side in the third direction (z direction) of the third transparent plate 400 and the side surfaces disposed side by side in the third direction (z direction) of the opaque plate 500. It is arranged to wrap. Frame 300 has a direction parallel to the first side (x direction) of both side surfaces 102 and the second transparent plate 200 facing the direction parallel to the first direction (x direction) of the first transparent plate 100. It is in close contact with both side surfaces 202 and is also in close contact with the projections 120 of the first transparent plate 100 and the projections 220 of the second transparent plate 200. Therefore, the first transparent plate 100 and The second transparent plate 200 is stably fixed to the inside of the frame 300.

The light emitting part 600 is configured such that light is incident through at least some of side surfaces 102, 104, 202, and 204 disposed side by side in the third direction (z direction) of the first transparent plate 100 and the second transparent plate 200. Disposed on at least some of the sides 102, 104, 202, 204. The light emitting unit 600 has side surfaces 104 and 204 formed to extend in a first direction (x direction) among the side surfaces 102, 104, 202 and 204 parallel to the third direction (z direction) of the first transparent plate 100 and the second transparent plate 200. ), And are arranged on the side located above.

The light emitting unit 600 includes a substrate 612 and a plurality of LED packages 610 mounted on the substrate 612. The LED package 610 is disposed on the upper side of the side (104,204) formed to extend in the first direction (x direction) of the first transparent plate 100 and the second transparent plate 200, so as to face the side Oriented. In the present exemplary embodiment, the light emitting part 600 has an upper side of the side surfaces 104 formed to extend in the first direction (x direction) of the first transparent plate 100, and the first direction (the second transparent plate 200). It is arranged in two rows and spaced apart at regular intervals along the first direction (x direction) so as to correspond to the upper side of the side 204 formed to extend in the x direction). Since the LED package 610 is used as the light emitting unit 600, the volume and weight of the light emitting unit 610 can be reduced, thereby effectively reducing the volume and weight of the entire LED signboard 1. In addition, there is an advantage to increase the luminous efficiency.

The reflective part 700 is positioned on the side opposite to the side where the light emitting part 600 is positioned such that the first transparent plate 100 and the second transparent plate 200 are disposed together with the light emitting part 600. The upper surface 710 facing the first transparent plate 100 and the second transparent plate 200 of the reflector 700 is formed of a mirror surface to reflect light. The reflector 700 is emitted from the light emitting part 600 to return the light passing through the first transparent plate 100 or the second transparent plate 200 to the center of the first transparent plate 100 and the second transparent plate 200 again. It serves to reenter it. Since the light emitted from the light emitting unit 600 by the reflector 700 stays on the first transparent plate 100 and the second transparent plate 200, it is possible to maintain the brightness of the LED signage 1 with little power. It can be effective. In addition, since the reflector 700 is cheaper than the LED package 610, it is advantageous in terms of cost.

Hereinafter, the operation form and effect of the LED signboard 1 according to the present embodiment will be described.

When power is applied to the light emitting unit 600, light is emitted. The light emitted from the light emitting part 600 is incident on the first transparent plate 100 and the second transparent plate 200, and the first transparent sphere 100 is disposed on the first transparent plate 100 and the second transparent plate 200. 110 and the second hollow sphere 210 is reached. The light reaching the first hollow sphere 110 is scattered in the colored paint painted on the first boundary surface 112 of the first transparent plate 100. Thus, the first boundary surface 112 emits light of the color of the paint. In addition, since the light reaching the second hollow sphere 210 is scattered at the roughened second boundary surface 212, light is emitted from the second boundary surface 212. Therefore, the first boundary surface 112 glows with the color of the paint, and the second boundary surface 212 glows with the color of light emitted from the light emitting unit 600.

As such, the first boundary surface 112 and the second boundary surface 212 constituting the outline of the character or the pattern are brightly shined so that the outline of the character or the pattern is clearly revealed, and the visibility is very good. In particular, even at night or in a room lacking light, characters or patterns are easily seen.

In addition, since the letters or patterns are displayed by being displayed on the first transparent plate 100 and the second transparent plate 200 which are arranged in parallel with each other, the three-dimensional sense is transmitted to the person looking at the letters or patterns.

Also, in the transparent first transparent plate 100 and the second transparent plate 200, only the first boundary surface 112 of the first transparent sphere 110 and the second boundary surface 212 of the second transparent sphere 210 are provided. Since light is scattered, the letters or patterns formed by the first boundary surface 112 and the second boundary surface 212 give a feeling of floating in the air. Therefore, it brings the mystery to the viewer, and has the effect of focusing the gaze.

Next, an LED signboard according to another embodiment of the present invention will be described with reference to the drawings.

That is, the outlines of 'A', 'B', and 'D' among the characters displayed on the LED signboard 2 according to the present embodiment are formed by the first boundary surface 112 and the two second boundary surfaces 212 and 812. , 'C', 'E' is formed by the first boundary surface 112 and one second boundary surface 212.

Since the second transparent plates 200 and 800 are formed in plural, the second boundary surfaces 212 and 812 of the plurality of second transparent plates 200 and 800 are contoured together with the first boundary surfaces 112 of the first transparent plate 100. In the form of contours. This makes the characters look deeper and convey a more three-dimensional sense. Therefore, it causes the viewer to feel more mysterious, and has the effect of focusing the gaze more.

On the other hand, in the above embodiment has been described as having an opaque plate 600, a transparent plate may be installed in place of the opaque plate 600. When the transparent plate is installed instead of the opaque plate 600, the foreground of the rear of the LED sign (1,2) can be seen from the front of the LED sign (1,2), the first transparent plate of the LED sign (1,2) Characters or patterns projected on the 100 and the second transparent plate 200 further doubles the visual effect as if floating in the air.

In addition, in the above embodiment, the first boundary surface 112 forms the outer contour of the letter or the pattern, and the second boundary surface 212 has been described as forming the inner contour. However, the first boundary surface 112 is different from the first boundary surface 112. The second boundary surface 212 may cooperate to form the outline of a character or a pattern. For example, when the character is Hangul, the first boundary surface 112 forms the contour of the consonant and the second boundary surface 212 forms the outline of the vowel of the characters. This may complete the outline.

As mentioned above, although some embodiments of the present invention have been described, the present invention is not limited thereto and may be embodied in various forms within the scope of the technical idea of the present invention.
