Abstract

(57) [Summary] (Correction) [Purpose] Using light emitting diodes, it is possible to perform stable lightning marking with excellent visibility at night and excellent fashionability. [Structure] A transparent plate 5 is attached to a main body panel 2 with one side end face facing a light emitting diode 4 in a light source type frame 3 and an engraving sign 6 on the back surface and a sticking reflection sheet 7 on the front surface respectively provided on the transparent plate 5. [Effect] In the darkness at night, it is possible to perform innovative electric marking with excellent visibility. Since the reflective sheet is attached, clear markings can be obtained when illuminated at night. It can be used semi-permanently without worrying about running out of balls.

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electronic sign board using a light emitting diode (LED) which is an optoelectronic semiconductor element.

[0002]

[Prior art]

 Conventionally, signboards have been set up near various construction sites as safety equipment, such as signs indicating that construction is prohibited, parking is prohibited, slow movement, etc. This is an outdoor stationary security sign for an unspecified number of people, and is a sign that occupies a certain space and gives a visual stimulus to its field of view. A variety of electronic signboards that use fluorescent lights for night lighting are also used.

[0003]

[Problems to be solved by the device]

 However, the conventional electronic signboard uses a fluorescent lamp as a lighting fixture, which is inferior in fashionability and novelty, and the visibility at night is not sufficient. In addition, there was a concern that the light bulb would burn out, so it was necessary to replace the bulb with trouble. The present invention has been made in order to solve the above-mentioned conventional problems, and uses visible light (mainly red) generated by a light emitting diode (LED) to make fashion excellent at night visibility. The purpose is to provide a rich, semi-permanent, stable and stable use of the electronic signboard.

[0004]

[Means for Solving the Problems]

 The gist of the present invention is that a light source type frame made of a groove-shaped material is attached to the main body panel integrally provided between the left and right columns in the horizontal direction and / or the vertical direction, and the light source type frames are arranged in parallel in the light source type frame. A transparent plate with engraved markings such as construction marks and markings on the back side and a reflective sheet attached on the front side is attached to the main body panel with one end face facing each of the above-mentioned light emitting diodes. This is an electronic sign board characterized by performing the electronic sign by reflecting visible light. The present invention will now be described in detail with reference to the following embodiments with reference to the drawings.

First, 2 is a main body panel integrally provided between the left and right cylindrical columns 1, 1 made of an extruded shape material such as aluminum extruded. Next, 3 is a groove-shaped light source frame, and a large number of light emitting diodes (LEDs) 4 are arranged in the light source frame 3 at appropriate intervals in the length direction. Further, 5 is a rectangular transparent plate made of transparent acrylic resin or the like. On the transparent plate 5, there are engraved signs 6 such as construction signs and markings on the back surface, and a sticking reflective sheet 7 on the front surface. Each is provided. Therefore, in the present invention, first, the light source type frame 3 having the above-described configuration is provided on the main body panel 2 in the horizontal direction (in the case of FIG. 1), in the vertical direction (in the case of FIG. 2), or in the horizontal direction and the vertical direction (in the case of FIG. 2). (In case of Fig. 3). Then, the transparent plate 5 having the above-mentioned structure is attached to the main body panel 2 as shown in the drawing with one end face facing a large number of the respective light emitting diodes 4 arranged in parallel in the respective light source type frames 3. Then, the visible light emitted from each light emitting diode 4 hits the engraved sign 6 on the transparent plate 5 and is reflected to perform the electronic sign according to the engraved sign 6. Reference numeral 8 is a screw for attaching the transparent plate 5 to the main body panel 2. In addition, many LED radiating elements mainly use red light as a visible ray, but recent LEDs have commercially available green and yellow light emitting elements.

[0006]

[Effect of device]

 In the present invention, a transparent plate with engraved markings on the back side is attached to the main body panel so that each light emitting diode arranged in parallel in the light source type frame faces one end face, and the visible light emitted from the light emitting diode (LED) is reflected. Since the electronic marking is performed by using the electronic marking, it is possible to perform the innovative electronic marking with excellent fashionability and excellent visibility in the dark at night. In addition, since a reflective sheet is attached to the surface of the transparent plate, clear markings can be obtained when the vehicle headlights are illuminated during the day or at night. Blinking is also possible, further improving the function of the electronic marking. Furthermore, there is no need to worry about running out of bulbs, there is no need to replace the bulb, and it can be used semipermanently.
