JP3121638U - Channel letter with LED as illumination source - Google Patents

Abstract

The present invention provides a channel character that can be created at a low cost by a simpler method and has a long lifetime.
Two fold lines are written with the same width from the end of the plate to the inside in parallel to the longitudinal direction of the metal plate. This is provided in the same way at both ends of the plate, and the plate is bent by approximately 180 degrees along the line provided inside. Further, it is bent at about 90 degrees along the other folding line. By this bending, a shelf portion on which the illumination member and the light diffusing member can be installed is provided inside the outer plate portion of the channel character, and a V-shaped notch is made at a necessary portion for producing the shape of the channel character. Next, separately prepare it in a form that can be stored on the inner surface of the channel character outer plate part, install the illumination member with the LED for illumination installed on the lower shelf part in the outer plate part, on the upper shelf part, In addition, two light diffusing plates prepared so as to be housed in the inner surface of the channel character outer plate portion are installed. Finally, the entire periphery of the light diffusing plate is adhered and fixed to the outer plate portion in a state where the whole is firmly fixed.

Description

  The present invention relates to a channel character having an LED as an illumination source, which can be used as a billboard for advertising / promotion, a guide sign, a guide light, an indicator light, or the like.

Various channel characters having shapes such as characters, figures, and patterns have been known. Many of the conventional channel letters use a neon discharge tube as the illumination source. A neon discharge tube requires a high voltage of 15,000 volts, so it must be handled with care, and it has a short life and requires frequent replacement work. In consideration of such circumstances, a device using an LED as an illumination source is disclosed. (See Patent Document 1.)
However, the method of creating channel letters is a method of providing an LED illumination member on the bottom surface and providing a light diffusing member on the top surface after creating an outer plate portion obtained by processing a metal plate so that the cross-section thereof becomes a U-shape. Therefore, when creating a channel character, it is necessary to fix it with bolts, which is very time-consuming and costly.

  An object of the present invention is to solve the present situation as described above, and to provide a channel character that can be created at a low cost with a simpler method and has a long lifetime.

  First, prepare a rectangular metal plate. Write two fold lines with the same width from the edge of the board to the inside in parallel with the longitudinal direction of this board. Install this on both sides of the board in the same way (Figure 1). Next, the plate is bent almost 180 degrees at the place of the wire provided inside. Do the same on both sides. In addition, bend it at 90 degrees along the other folding line. By this bending, a shelf part can be installed on the inside of the outer plate part of the channel letter where the lighting member and the light diffusion member can be installed (Figure 2). Next, make a V-shaped cut at the required location so that the shape of the channel character can be created. By repeating the operation of folding the metal plate at an appropriate angle at the cut, it is possible to form certain characters and figures. Next, in the shelf under the outer plate part, prepare it in a form that can be stored separately on the inner surface of the channel character outer plate part, and install the lighting member with the LED for lighting already installed. Next, two light diffusing plates prepared in a form that can be stored inside the channel letter outer plate are installed on the upper shelf of the outer plate. Finally, with the whole area firmly fixed, the periphery of the light diffusing plate is adhered and fixed to the outer plate.

  Since the channel character outer plate can be created with only one plate, it can be created by a simpler method than the conventional method, and the cost can be reduced accordingly. The creation time can be shortened, and even a less skilled worker can create it. The use of two light diffusing plates increases the viewing angle and can provide channel characters that can be recognized from a distance.

  Taking the channel letter A as an example, the content of the present invention will be described with reference to the drawings. FIG. 1 shows a state in which a fold line and a cut line for processing are written on one metal plate. FIG. 2 shows the cross-sectional shape of the outer plate after being bent in the longitudinal direction, 2 is a shelf for receiving the light diffusing member, and 3 is a shelf for receiving the LED illumination member. FIG. 3 shows the illuminating member 9 and the light diffusing members 6 and 7 on the external plate 4 obtained by bending the cut portion as a base point. FIG. 4 shows a complete overview of the channel letters.
