Luminous sign using LED {DISPLAY DEVICE USING LED MODULE}

The present invention relates to a light-emitting sign using the LED; More specifically, the present invention relates to a light-emitting sign using an LED capable of realizing a high brightness advertisement through a light emitting device, that is, an LED.

In general, the luminous signs used for advertising indoors or outdoors are installed in restaurants, shopping malls, or building walls to express necessary characters, symbols, or images. There are neon signs using neon gas so that they can be easily recognized. However, the production cost of Panaplex-type advertisements has a considerable disadvantage, and in the case of a display device using neon signs, the brightness is high, so the naked eye is easy to identify, but the neon tube is exposed, which may cause damage. The disadvantages are high consumption and significant heat generation.

In order to solve this problem, a display apparatus using R (Red), G (Green), and B (Blue) light emitting diodes (hereinafter, referred to as LEDs) has been disclosed in Korean Patent Registration No. 10-0365307.

As shown in FIG. 1, the indoor / outdoor advertising apparatus disclosed in the prior patent No. 10-0365307 is shown; The paint 1 having a predetermined thickness is applied to the mold 1 having a predetermined shape on the inner surface and the paint 2 on the inner surface of the mold 1 to reflect the light of the light emitting element 3. A secondary transparent epoxy (5) is applied to bury the primary epoxy and acrylic material (4) and the light emitting element (3) installed above the primary epoxy and acrylic material (4) to disperse the light of the light emitting element (3) (5). ) And a tertiary epoxy (6) applied to the upper surface of the secondary transparent epoxy (5) to facilitate light emission.

Therefore, in the indoor / outdoor advertising device; Light emitted from the light emitting element 3 is diffusely reflected by the primary transparent epoxy and acrylic material 4, and the reflected light is applied to the upper surface of the primary transparent epoxy and acrylic material 4 and the secondary transparent epoxy 5 is applied. Distributed through. Subsequently, light dispersed through the secondary transparent epoxy 5 emits light through the tertiary epoxy 6 in which the translucent fluorescent pigment and the light dispersant are mixed. This enables not only detailed and diverse fonts, color and image expressions, but also excellent advertising effects at night as well as during the day.

However, in the case of the above-described indoor / outdoor advertising apparatus of Patent No. 10-0365307, there is a disadvantage in that it is manufactured through a complicated process of filling transparent epoxy in the mold 1 three times, and the embedded light emitting device 3 The focus of the eye is recognized by the naked eye, the surface brightness is uneven, of course, there is a problem of eye fatigue when looking for a long time. In addition, there is a disadvantage that the light emitting surface is uneven due to shrinkage deformation as the epoxy filled to a considerable thickness is cured, and a yellowing phenomenon occurs in the epoxy layer in which the light emitting device 3 is embedded, and thus the brightness of the light emitting device is increased. It causes dropping. In addition, in the case of the light emitting device 3 composed of LED, considerable heat is generated, and since the light emitting device 3 is completely embedded through the epoxy, the heat dissipation effect is remarkably dropped, and its life is shortened.

The present invention is to solve this problem; An object of the present invention is to provide a light-signal using the LED that can be manufactured through a simple process, as well as to implement a high-brightness advertisement by improving the structure of the light-emitting sign that the LED module is accommodated.

A space for accommodating the module 30 is formed. 3 and 4, a white reflective sheet 13 is attached to the bottom 11 and side 12 of the advertising frame 10, which emits light emitted from the LED module 30. This is to maximize the advertising effect by diverging to the outside only through the translucent color epoxy 50 of the front cover 40 to be described later.

3 and 4, the partition walls 20 are made of an opaque material to partition the interior space of the advertisement frame 10 into a plurality of LED arrangement spaces 20a and a reflective sheet along the wall thereof. (21) is attached. This is to prevent the light emitted from the LED module 30 from leaking to the neighboring LED arrangement space (20a). That is, the LED arrangement spaces 20a are partitioned in a manner similar to the shape of the advertisement text to be advertised through the partition wall 20, and the reflective sheet 21 attached to the partition wall 20 also emits light from the LED module 30. This is to diverge to the outside only through the translucent color epoxy 50 of the front cover 40.

On the other hand, the LED module 30 is disposed similar to the form of the ad text in the interior of the LED placement space (20a) partitioned by the partition wall 20, in the embodiment of the present invention in conjunction with the LED chip (CHIP LED) The bottom surface of the arrangement spaces 20a was disposed. In addition, as shown in FIG. 4, the light emitting focus of the chip LEDs is directed toward the bottom of the LED arrangement spaces 20a so that the light emitting light is emitted in a backlight form. For sake. In the present invention, by placing the LED module 30 (chip LED) in the form similar to the form of the advertising text in the LED placement space (20a), it was possible to maximize the advertising effect through the light emission. In addition, the LED modules 30 are operated and controlled by a controller (not shown) in which a power supply is programmed. The LED modules 30 may be turned on / off at regular intervals through power relays (not shown). Of course, it can be controlled by various types such as turning on / off in the form of panorama with time difference.

3 and 4, the front cover 40 is made of an opaque panel and is disposed to cover the front surface of the advertisement frame 10 in which the LED modules 30 are disposed. An editorial projection window 41 is punctured in a portion corresponding to 20a, and the editorial projection window 41 is filled with a translucent color epoxy 50 to form an advertisement text. Accordingly, the light emitted from the LED module 30 exits to the outside only through the translucent color epoxy 50 of the front cover 40 and appears to surface-emit from the front cover 40.

The front cover 40 is manufactured through a projection window drilling step S1, a sheet attaching step S2, and a color epoxy filling step S3, as shown in FIG.

And the sheet attaching step (S2) is a process of attaching the light-transmitting sheet 60 to the bottom surface of the front cover 40 perforated advertising copy projection window 41, which puts the front cover 40 on the workbench This is to pour a colored epoxy in the form of gel on the text projection window 41. In addition, the color epoxy filling step (S3) is, as described above, by putting the front cover 40 attached to the light-transmitting sheet 60 on the workbench and then molding by pouring a gel-type translucent color epoxy 50, Its color can be set by the operator according to the ad text. At this time, as the transparent color epoxy 50 is cured, the light-transmitting sheet 60 of the corresponding portion is also integrated, whereby the light emitted from the LED module 30 can only be emitted to the outside through this.

<Description of the operation and effect of the light-emitting object according to the embodiment of the present invention>

Next, a description will be given of the operating state of the light-emitting sign using the LED configured as described above.

When power is supplied to the LED module 30 of the light emitting sign according to the present invention, it emits light. As shown in FIG. 6, the light is reflected inside the partitioned LED arrangement spaces 20a and radiates to the outside only through the editorial projection window 41 of the front cover 40, that is, the translucent color epoxy 50. Advertising effect can be obtained.

In addition, as shown in FIG. 4, since the internal space of the advertising frame 10 is partitioned into the opaque partition walls 20 to which the reflective sheet 21 is attached, light from the LED modules 30 is reduced. Not only the contrast between the on and off of the LEDs that are not diffused into the neighboring LED arrangement space 20a is clearly displayed, but the contrast is clearly expressed according to the color of the translucent color epoxy 50.

That is, the light emitted from the LED modules 30 is reflected by the reflective sheets 13 and 21 and finally emits light through the transmissive color epoxy 50 of the front cover 40. This is done.

In other words, the light emitted from the LED modules 30 accommodated in the advertisement frame 10 may implement a clear lighting advertisement by the translucent color epoxy 50, and the LED disposed inside the advertisement frame 10. The modules 30 are made invisible to the naked eye by the translucent color epoxy 50.

In particular, since the LED module 30 to which the chip LED is applied is disposed so that the light emitting focus is directed toward the bottom 11 (bottom) of the advertising frame 10, the light emitting focus thereof is also not visible from the outside. Due to this configuration, the thickness of the advertising frame 10 may be made thinner, but the light emitting focus of the LED modules 30 may be invisible from the outside.

On the other hand, in the embodiment of the present invention has been described as implementing the advertising effect only through the front of the advertising frame 10, it is not limited to this can be implemented simultaneously through the front / rear of the advertising frame 10, even in this case chip By arranging LED modules 30 to which LEDs are applied in the reverse direction, the thickness of the advertising frame 10 may be configured to be thin.
