BACKGROUND OF THE INVENTION
The present invention belongs to the technical field of light-emitting displays used for advertising, decoration, or display.
[0002]
[Prior art]
Conventionally, as such an indicator, there is a neon tube, but since the neon tube is formed of a glass tube, there is a problem that the tube is broken, and there is a problem that it is broken, and it is formed in a predetermined shape. In order to attach the manufactured one, there is a problem that the transportation or the like is troublesome and complicated, and the shape cannot be changed later on site.
On the other hand, there is a device using a light-emitting element (light-emitting diode) such as a light-emitting diode that can be used semi-permanently without fear of running out of balls. In Japanese Laid-Open Patent Publication No. 61-112392, Japanese Utility Model Laid-Open No. 2-78983, Japanese Utility Model Laid-Open No. 2-81580), there is a problem that the shape cannot be changed later, as in the case of the neon sign.

[Problems to be solved by the invention]
Therefore, there are lead wires and light emitting elements that are bare and can be mounted freely by bending the lead wires as necessary, but this one can be placed in an indefinite place such as a tree and in an indefinite direction. However, there is a problem that workability is lacking because it is necessary to mount and fix each light emitting element one by one while considering the light emitting direction.
On the other hand, a lead wire and a light emitting element are enclosed in a flexible cylinder so that they can be bent arbitrarily (for example, Japanese Utility Model Laid-Open No. 59-1555066, Japanese Patent Laid-Open No. 6-10320). There is. However, this product is troublesome and cumbersome to enclose in a cylindrical body, and since it is free to twist in the direction around the axis, it is difficult to mount the light emitting element with a constant orientation, especially in the light emitting direction like a light emitting diode. The display direction tends to be uneven if the directivity is high, and if it is configured to be visible from an unspecified direction, anyway, it is difficult to do this when you want to direct it in a certain direction like an advertising light. is there.
On the other hand, those in which lead wires are embedded in a flat tape-like flexible material are known, for example, in JP-A-3-61990 and JP-A-8-36368. The former has a structure in which the light emitting element is attached to the flat tape surface, so that the light emitting direction is perpendicular to the tape surface. For this reason, for example, for mounting on a curved surface that rotates around the outer periphery of the cylinder. Is suitable, but if it is attached so as to draw a curved line in a plane, there is a problem that the flat tape surface rises like a wave, and in this case it cannot be adopted. In the latter case, since the light emitting element is attached to the side edge of the flat tape material, the light emitting direction of the light emitting element faces the width direction of the flat tape material. It needs to be installed upright, but because it is made of flat tape material, it may not be able to stand on its own and it may fall over easily, so many stops are required to keep it in an upright position so that it does not tilt or fall down accidentally. There is a problem.
[0004]

Next, embodiments of the present invention will be described with reference to the drawings. 2 to 5, reference numeral 1 denotes a light-emitting display device according to the first embodiment, and the light-emitting display device 1 is configured by using a long base material 2. Is composed of two parts made up of first and second halves 2a, 2b formed by molding a flexible material having rubber elasticity. In other words, the base material 2 has a substantially long rectangular cross section and is configured to divide between both short sides by two, but in a state where both halves 2a and 2b are abutted, a substantially pentagonal shape is formed on one short side. was the (corresponding to the inner cylinder portion of the present invention) hollow chamber 2c is formed along the longitudinal direction, which base material 2 by the Rutotomoni have any section tubular, as illustrated in the side short side The through holes 2d are opened with a predetermined interval in the longitudinal direction . The hollow chamber 2c is provided with a lead wire 3 and a resistor 4, while the lead wire 3 is elongated in the through hole 2d as shown in the figure, and a plurality of light emitting diodes 5 connected thereto. Is installed through. Here, since the through hole 2d elastically supports the light emitting diode 5, it is preferable that the inner diameter is substantially equal to or slightly smaller than the outer diameter of the light emitting diode 5.
[0006]
The other short side of the substrate 2 is solid, but the butt surfaces of both halves 2a, 2b are formed with concavo-convex portions 2e, 2f that are fitted in a dovetail shape and prevented from being removed. Thus, the two halves 2a and 2b are integrated together. Incidentally, the halves 2a and 2b may of course be bonded to the butted surfaces using an appropriate adhesive.
Reference numeral 6 denotes a covering material for covering the base material 2, and the covering material 6 is also made of a soft material having flexibility. The covering material 6 corresponds to the base material 2. The cross section has a rectangular shape with one short side opened in accordance with the diameter of the light-emitting diode 5.
The length of the base material 2 can be set to an appropriate length if necessary, but the lead wires 3 extending from both ends of the base material 2 are connected to couplers 11 and 12 that can be inserted into and removed from each other. The configuration is such that an extended connection is possible, and the setting is such that light emission control is performed by connecting to a light emission controller (not shown).
[0007]
In the first embodiment of the present invention configured as described above, the light-emitting display device 1 is manufactured in advance in the half hole portion of the through hole 2d of one half portion 2a (of course, the half portion 2b). The light-emitting diode 5 connected to the lead wire 3 and the resistor 4 is sandwiched and temporarily held, and the lead wire 3 and the resistor 4 are wired in the half chamber of the hollow chamber 2c, and then the other half portion 2b is abutted. The two halves 2a and 2b can be formed by fixing them (in this embodiment, the concave and convex portions 2e and 2f are fitted together), and can be easily formed by covering them with the covering material 6 if necessary for makeup or the like. can do.
[0008]
Moreover, since the light-emitting display device 1 formed in this way has a thick three-dimensional structure, it can stand on its own as it is, and therefore a stopper for making it stand alone is not necessary. For example, the covering material 6 can be easily attached by attaching the covering material 6 to the attachment surface in advance and fitting the light emitting display 1 to the covering material 6 later.
Moreover, since the light emitting display 1 is flexible, it can be bent so as to draw a curve on a plane. In particular, in the present embodiment, the light emitting display 1 has a base material 2 having a cross-sectional length. Since the light emitting diode 5 is disposed on the short side of the square and the long side is bent along the curve, it is easy to bend and it can be avoided that it rises like a wave when bent, As a result, the light emitting diode 5 is mounted in a state where the light emitting direction is well aligned in the front direction.
Incidentally, the present invention is intended to bend the light emitting display 1 in a curved shape, and is not intended to bend at an angle. This is because bending with such an angle can be achieved if the end portions of the light emitting display 1 are brought into contact with each other with an angle.
