Description: INDOOR/OUTDOOR ADVERTISING DEVICE AND METHOD FOR MANUFACTURING THE SAME Technical Field The present invention relates to an indoor/outdoor advertising device and a method for manufacturing the same, and in particular, to an indoor/outdoor advertising device used for indoor/outdoor advertisement materials or signboards (e.g., indoor decorations, outdoor signboards, clocks, guiding boards, scoreboards, displays on show windows, etc.) that can be easily manufactured due to a simple structure and can provide an outstanding advertisement effect not only at nights but also during the daytime by emitting lights from the light elements throughout surfaces thereof with less consumption of an electric power. Background Art In general, neon lamps are mainly used for advertisement materials or neon signs. However, neon lamps are apt to be damageable due to an exposure of neon tubes therefrom. Furthermore, neon lamps consume a considerable amount of electric power due to a use of high electric voltage. Moreover, neon lamps have a low durability and can hardly be used under water. A light emitting structure using a light emitting diode (LED) has been suggested in recent days as means to supplement the above drawbacks of neon lamps. The conventional light emitting structure is manufactured by installing LEDs on a transparent floor and pouring polymer resin thereonto. However, this manufacturing method poses problems in controlling thickness of the light emitting structure to be slim as well as in providing a light emitting surface of various colors due to a comprehensively dark tone of the advertisement materials employing the LED, which is the only source of brightness. Japanese Laid-Open Patent No. Hei 11-195564, filed on July 9, 1999 and laid open on November 2, 2000, discloses an LED for display. In the LED for display disclosed in Japanese Laid-Open Patent No. Hei 11-195564 as shown in Figs. 7 and 8 thereof, a light emitted from an LED 20 travels straight after penetrating a through hole 31 formed in the reflecting material 30 and is reflected through both side walls thereof, or the LED 20 only is installed inside of a mold frame 1 1 without any reflecting material for emitting a light. This conventional technology employed an additional reflecting material 30 of a funnel shape to emit the light from the LED 20 as shown in Figs. 7 and 8 because the light from the LED 20 is not properly dispersed or emitted in case of Figs. 9 and 10. However, the reflecting material 30 can hardly be manufactured into a funnel shape and combined with the LED 20, thereby posing difficulties in the manufacturing process and increasing the manufacturing cost. Disclosure of Invention It is, therefore, an object of the present invention to provide an indoor/outdoor advertising device and a method for manufacturing the same that can achieve a dispersion effect without using any additional funnel but with or without an epoxy molding on light elements by emitting the light throughout the entire emitting surface of an advertisement material at nights or even during the daytime, and that consumes a less amount of electric power by employing LEDs and can be safely used under water owing to an epoxy molding. To achieve the above object, there is provided a method for manufacturing an indoor/outdoor advertising device, comprising: a first step of manufacturing a mold (panel) for characters or shapes of a signboard or an advertising material; a second step of coating a luster urethane paint on a lower portion or on both side walls of the panel at a predetermined thickness; a third step of first coating a transparent epoxy and acrylic material at a thickness ranged 0.5-5mm on an upper surface of the luster urethane paint; a fourth step of fixedly lining a plurality of light elements irrelevant to size or shape at intervals ranged 1 -5cm in accordance with the mold for characters or shapes so as to stream electricity; a fifth step of lining out one end tip of + and - lead wires connected to the plurality of light elements from the mold; a sixth step of secondly coating the transparent epoxy to the extent of covering the plurality of light elements; and a seventh step of thirdly coating the epoxy, which is a mixture of a translucent fluorescent pigment with a light dispersing agent, on an upper surface of the transparent epoxy. According to one aspect of the present invention, the method for manufacturing the indoor/outdoor advertising device is characterized by aligning polycarbonate in a mold shape instead of the epoxy, which is a mixture of a translucent fluorescent pigment and with a light dispersing agent, on an upper surface of the transparent epoxy. According to another aspect of the present invention, the method for manufacturing the indoor/outdoor advertising device is characterized by covering the mold of a transparent acrylic material with a space as thick as the second transparent epoxy material that would have been coated, and by coating the epoxy mixed with a translucent fluorescent pigment. According to still another aspect of the present invention, the method for manufacturing an indoor/outdoor advertising device is characterized by covering the mold of a transparent acrylic material with a space as thick as the transparent epoxy that would have been coated, and by aligning the polycarbonate thereon in a mold shape. According to still another aspect of the present invention, the method for manufacturing an indoor/outdoor advertising device is characterized by employing LEDs as light elements and uniformly aligning the LEDs upward, downward or in a transversal direction so that the head portions of the LEDs can be adjacent to a bottom surface or side surfaces thereof. An indoor/outdoor advertising device employing light elements as a light source according to the present invention comprises: a mold of a predetermined shape; a first epoxy and acrylic material first coated on an inner surface of the mold for reflecting lights from the light elements; a second transparent epoxy material coated for dispersing the lights from the light elements installed at an upper portion of the first epoxy and acrylic material; and a third epoxy material, which is a mixture of a translucent fluorescent pigment with a light dispersing agent, aligned on an upper surface of the second transparent epoxy material for smoothing emission of lights.

Best Modes for Carrying out the Invention Best modes for carrying out the present invention will be described herein below with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. Fig. 6 is a flow chart illustrating the method for manufacturing an indoor/outdoor advertising device according to a first best mode for carrying out the present invention. Referring to Fig. 6, a panel is produced by manufacturing a mold for characters or shapes of a signboard or an advertising material (SI). A luster urethane paint 2 is coated on a lower portion and on both side walls of the panel 1 at a predetermined thickness (S2). A first transparent epoxy and acrylic material 3 is coated on an upper surface of the luster urethane paint 2 at a thickness ranged l-5mm so as to generate a light reflecting layer (S3). Light elements of different sizes or shapes (e.g., LEDs) are soldered and aligned along the wiring 5 in accordance with the mold 1 for characters and shapes on the coated first transparent epoxy and acrylic material 3 at intervals of l-5cm upward, downward or in a transversal direction (S4). Here, the light elements are not bound by size or shape, and may be of any shape such as a cylindrical shape, a rectangular chip shape or a triangular shape. When the wiring 5 has been aligned downward as shown in Fig. 1 , the light elements 4 can be uniformly aligned upward. When the wiring 5 has been aligned upward as shown in Fig. 2, the light elements 4 can be uniformly aligned downward. In that case, the light elements 4 should be installed to be in contact with the first transparent epoxy and acrylic material 3. The reason for installing the light elements 4 to be in contact with the first transparent epoxy and acrylic material 3 is to secure a sufficient light emitting space by scattering the lights reflected from the light elements so as to eliminate the dark part on a comprehensive basis and to smooth emission of the lights. In case of another best mode to be described later (as shown in Figs. 3 and 4), the wiring 5 may be aligned on side surfaces of the mold 1 for characters and shapes and the light elements 4 may be connected to the wiring 5. Meanwhile, power is supplied from a lead wire 8, which is formed by penetrating a hole through the mold 1 and lining out the + and - lead wires of the wiring 5, on which the light elements 4 are aligned (S5), from the mold 1. A light scattering layer is formed by coating the second transparent epoxy material 6 to the extent of covering the plurality of light elements 4 (S6). A third epoxy material 7, which is a mixture of a translucent fluorescent pigment with a light dispersing agent, is coated on an upper surface of the second transparent epoxy material 6. Here, the light dispersing layer is formed on the third epoxy because the translucent fluorescent pigment is mixed therewith (S7). The third epoxy material 7, which is a mixture of the translucent pigment with the light emitting material, may also formed by mixing a white translucent fluorescent pigment with a color pigment so as to save an amount of the color pigment. An advertising material is completely manufactured as shown in Fig. 5 by adding a diffusion agent to the third epoxy material 7 to diffuse the light from the light dispersing layer (S7, S8). Fig. 2 is a diagram illustrating a method for manufacturing an indoor/outdoor ' advertising device according to a second best mode for carrying out the present invention. Instead of the third epoxy material 7, which is a mixture of the translucent fluorescent pigment with the light dispersing agent, polycarbonate (PC) 10 is formed in a mold shape and aligned on an upper surface of the second transparent epoxy material 6. Fig. 3 is a diagram illustrating a method for manufacturing an indoor/outdoor advertising device according to a third best mode for carrying out the present invention. A transparent acrylic material 9 is aligned with a space as thick as the second transparent epoxy material 6 that would have been coated, and polycarbonate 10 is aligned in a mold shape thereon. Fig. 4 is a diagram illustrating a method for manufacturing an indoor/outdoor advertising device according to a forth best mode for carrying out the present invention. In the fourth best mode, the transparent acrylic material 9 is aligned on upper surfaces of the light elements 4 with a space as thick as the second transparent epoxy material 6 that would have been coated, and the third epoxy material 7, which is a mixture of the translucent fluorescent pigment with the light dispersing agent, is coated thereon. The third and the fourth best modes shown in Figs. 3 and 4 are mainly applied to a signboard of a large scale. No coating of the second transparent epoxy material 6 serves to reduce time for hardening the epoxy as well as to reduce the weight of the advertising material, thereby easing the working process and saving the cost. If a power connected along the lead wire 8 is switched on upon completion of the advertising material as described above, the power is supplied to the wiring 5 along the lead wire 8, and subsequently to the plurality of light elements 4 connected to the wiring 5 so as to enlighten the light elements 4. If the light elements 4 are enlightened, the light generated from the light elements 4 is scattered from the first transparent epoxy and acrylic material 3, and dispersed through the second transparent epoxy material 6 coated on an upper surface of the first transparent epoxy and acrylic material 3. The light dispersed through the second transparent epoxy material 6 emits light through the third epoxy material 7, which is a mixture of the translucent fluorescent pigment with the light dispersing agent. The light dispersed through the second transparent epoxy material 6 is emitted the polycarbonate 10 in case of the second best mode, while the lights from the light elements 4 is emitted through the transparent acrylic material 9 and the polycarbonate 10. On the other hand, the lights from the light elements 4 is emitted throughout the surface of the transparent acrylic material 9 and the third epoxy material 7. Thus, the present invention can achieve an advertising effect by using a particular material. Using the light elements 4 can serve to reduce consumption of the electric power, thereby providing a great economic benefit. The conventional advertising device is generally manufactured to have a display window composed of light emitting dots by applying the light elements. However, the advertising device according to the present invention is manufactured to have a structure of dispersing lights from the light elements that is characterized by smoothly dispersing the lights onto characters, numbers or pictures throughout a surface of the display window of a variety of displaying materials. According to the present invention, steel plates, stainless steel plates, stone materials, acrylic materials, brass wire, wood or panels made of diverse synthetic materials can be used for the mold 1 to display characters, numbers or pictures. As described above, the present invention can achieve a superior advertising effect in comparison with the conventional neon lamps, etc. by coating a plurality of epoxy layers on desired characters or shapes and by aligning the light elements so as to stream electricity therealong as well as by emitting lights through the light elements when supplying the power. The present invention provides additional advantages of expressing a variety of character styles, colors or images as well as of achieving outstanding advertising effects not only at nights but also during the daytime. Further, the advertising device manufactured according to the present invention is rarely damaged or out of order, and can be used on a semi-permanent basis. In addition, employing the LEDs for light elements serves to reduce the maintenance cost due to their less consumption of an electric power as well as to carry the same advertising effect under water as in the air. While the invention has been shown and described with reference to certain best modes thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
