FIG. 1 is an exploded perspective view of a double-sided light emitting type signboard according to an embodiment of the present invention, FIG. 2 is a view showing a double-direction illumination body of FIG. 1, FIG. 3 is a perspective view of the attachment / FIG. 4 is a view showing a coupling relation between the first cover and the attaching / detaching member shown in FIG. 1;

A double-sided LED signboard 100 according to an embodiment of the present invention includes a first cover 10, a bi-directional illuminator 20, and a second cover 30.

The first cover 10 may be coupled to the left side or the right side of the bidirectional illuminator 20. Here, the left side can be called the front side and the right side can be called the rear side. Of course, the opposite can also be true. In the embodiment of the present invention, the first cover 10 may have a rectangular shape.

The first cover 10 includes an opaque hollow body 13 formed at a predetermined position on the inner side surface of the cover 10 along the inner side at an equal height and having a locking protrusion 12 directed inward, 13 and a translucent window 11 covering one opening of the body 13.

Here, the body 13 may be formed of a metal such as aluminum or the like and may have a rectangular ring shape.

The semitransparent window 11 may have a rectangular shape.

The translucent window 11 is formed of a translucent resin material having a predetermined thickness, and a diffusion sheet (not shown) or a diffusion plate (not shown) may be formed on one surface. That is, the translucent window 11 diffuses the light emitted from the illuminating means 22 formed on the opposite surface of the bidirectional illuminator 20, as it includes the diffusing sheet or the diffuser plate, and externally diffuses the emitted light.

The width of the engaging portion 14 of the body 13 coupled with the translucent window 11 is made as narrow as possible in order to display the displayable characters or symbols through the semitransparent window 11 as much as possible. Conventionally, when the body 13 and the semitransparent window 11 are coupled to each other, the coupling portion of the body is joined to the edge of the translucent window 11 with a width of about 1 cm. In this manner, characters or symbols can not be displayed in the area of the semi-transparent window 11 by the width of the coupling portion of the body. Therefore, in the embodiment of the present invention, the width of the engaging portion 14 of the body 13 is minimized to maximize the displayable characters or symbols through the translucent window 11. At this time, the coupling portion 14 of the translucent window 11 and the body 13 can be coupled using a tackle.

The second cover 30 may be coupled to the right side or the left side of the bidirectional illuminator 20. In the embodiment of the present invention, the second cover 30 may have a rectangular shape.

The second cover 30 is configured similarly to the first cover 10 described above. That is, the second cover 30 includes the body 33 and the translucent window 31 in the same manner as the first cover 10 described above. Here, the body 33 is formed of the same material and construction as the body 13, and the semitransparent window 31 is formed of the same material and construction as the semitransparent window 11 described above. Therefore, the person skilled in the art will be able to fully understand the body 33 and the semitransparent window 31 based on the description of the body 13 and the semitransparent window 11, A detailed description of the semitransparent window 31 will be omitted.

The bidirectional illuminator 20 is interposed between the first cover 10 and the second cover 30 and irradiates light in both directions (for example, front and rear, leftward and rightward, upward and downward, etc.). The bidirectional illuminator 20 includes a substrate 21, light emitting means 22, and a removable member 23.

The substrate 21 may be formed in a rectangular shape.

For example, the attachment / detachment member 23 may be composed of a plurality of attachment / detachment members 23, and the plurality of attachment / detachment members 23 may be fixed with a transparent tape or the like after being fitted to the rim of the substrate 21 at predetermined intervals so as to be spaced apart from each other .

The attaching / detaching member 23 has a first fitting portion 23a to be engaged with the rim of the substrate 21, a second fitting portion 23a to be fitted to the engaging protrusions 12 of the first cover 10 or the second cover 30, 23c and 23d which are in close contact with the upper and lower portions of the inner surface of the body 13 and 33 of the first cover 10 or the second cover 30, respectively. The contact portions 23c and 23d serve to push the inner sides of the bodies 13 and 33 of the first cover 10 or the second cover 30 in the outward direction, 2 cover 30 and the bidirectional illuminator 20 are strengthened.

Here, it is preferable that the attaching / detaching members 23 are alternately disposed opposite to each other along the rim of the substrate 21 as shown in Fig. In this case, it is easy to attach the first cover 10 to the left side of the bidirectional illuminator 20 and attach the second cover 30 to the right side of the bi-directional illuminator 20.

Although the first cover 10, the bidirectional illuminator 20 and the second cover 30 are rectangular in shape, the first cover 10 and the bi-directional illuminator 20 may have different shapes depending on the shape of the signboard to be made. The shape of the second cover 20 and the shape of the second cover 30 may be different.
