Description

3D light emitting sign using LED {DISPLAY DEVICE USING LED MODULE}

The present invention relates to a light emitting sign using an LED, and more particularly, a light emitting device, that is, an LED (light emitting diode module) to emit light toward the front and the back of the sign to display an advertisement text more three-dimensionally. It relates to a stereoluminescence sign used.

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, Panaplex-type advertisements have significant disadvantages in manufacturing cost. In the case of display devices using neon signs, the brightness is high, so visual identification is easy, but neon tubes are exposed, which may cause damage, and power consumption is consumed because high voltage is used. Has a high disadvantage.

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. Accordingly, not only can it express delicate and various fonts, colors, and images, but also during the day, the ad text itself produced three-dimensionally as it is, advertises specific characters, and at night, the characters are illuminated by the light of the light emitting device 3 built-in. Will be displayed.

However, in the case of the above-mentioned indoor / outdoor advertising apparatus, the light emitting element embedded in the advertising text, ie, the LED, is a conventional method of surface-emitting the front surface of the ad text. There is a limit to maximizing the effect.

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 three-dimensional luminous sign using the LED that can be expressed more three-dimensionally by advertising the light from the LED module toward the front and rear of the luminous sign at the same time.

It consists of a halo-LED 23 emitting light. The LED module 20 is fixed to fill the transparent epoxy resin 13 so as to have a predetermined thickness on the inner bottom of the inner character channel 10, which causes the LED module 20 is buried and completely waterproof. . At this time, the front end of the LED-LED module 20 and the LED-LED 22 and the LED-LED 23 are filled with a transparent epoxy resin of a gel type so that the front end of the LED module 20 is exposed. To diverge. (For reference, since the upper surface of the chip-shaped LED is already waterproofed through the molding process in the production process, it is not required to waterproof to this part.) As such, the transparent epoxy for the fixed arrangement of the LED module 20 The use of the resin 13 is not only excellent in adhesive performance, but also because it can exhibit a perfect waterproof effect when cured.

The space which can accommodate this is formed. The member constituting the editorial frame 41 is preferably made of an opaque (light impermeable) material so that light does not leak to the outside, which is the light from the all-LED 22 of the LED module 20. This is mostly to diverge forward to maximize the advertising effect. In addition, an uneven portion 41a is formed inside the front portion of the editorial frame 41 along the edge of the colored epoxy surface emitting layer 42 so as not to be separated when the color epoxy surface emitting layer 42 is cured. That is, when the edge of the color epoxy surface light emitting layer 42 is hardened while contacting the uneven portion 41a, the epoxy surface at the front of the editorial frame 41 even if the epoxy surface light emitting layer 42 shrinks and deforms slightly with temperature change. The light emitting layer 42 does not fall. In the embodiment of the present invention, the ad text frame 41 is composed of a metal plate, but is not limited thereto, and may be made of an opaque synthetic resin (acryl), wood, or a plate made of various compounds. Meanwhile, in FIG. 3 and FIG. 5, reference numeral “41b” is a screw hole drilled in the editorial frame 41, which is drilled to coincide with the screw hole 12a of the side wall surface 12 of the inner character channel 10. . Further, reference numeral 43 is a reinforcement-bridge welded to the editorial frame 41, which is for reinforcement and text formation of the editorial frame 41.

On the other hand, the epoxy surface light emitting layer 42 constituting the outer character channel 40, as described above, the gel-type color epoxy to have a predetermined thickness inside the front portion to close the open front of the editorial frame 41 It is molded by filling the resin, through which the light emitted from the all-LED 22 of the LED module 20 is shining in front of the ad text frame (41). The color epoxy surface emitting layer 42 is disposed by inverting the open front of the editorial frame 41 to abut on a flat work surface (not shown), and the front gap of the work surface and the creative frame 41 by paraffin or glue gun. After sealing, the gel type color epoxy resin is filled to have a thickness. At this time, since the colored epoxy surface emitting layer 42 is integrally cured at the front of the editorial frame 41 having the uneven portion 41a formed along the edge, even if a slight shrinkage deformation occurs due to temperature change, the color epoxy surface emitting layer 42 is not separated. . The color epoxy surface emitting layer 42 is composed by applying a color epoxy resin having a variety of colors by mixing fluorescent pigments, which causes the interior of the ad text frame 41 of the outer character channel 40 formed air layer is visible from the outside Do not. Therefore, the light emitted from the electroluminescent LED 22 of the LED module 20 appears to surface-emit through the color epoxy surface emitting layer 42.
