PROBLEM TO BE SOLVED: To provide a spontaneously light-emitting apparatus capable of preventing a light-emitting diode from peeling off from a wiring caused by twist of a reflecting vest having a built-in light-emitting diode in a wearing operation. SOLUTION: A wiring 5 for sending electricity is arranged on the underside of a movable substrate 4 and a hole is provided between the wiring 5 for sending electricity. The light-emitting part of the light-emitting diode 2 is installed in the hole so as to come out on the surface of the movable substrate 4 and bonded from the back of the movable substrate 4 to the wiring 5. A hard plate 9 for protecting the bonded part is connected to the bottom. A semispherical transparent resin 1 having a flat top is laid and fitted on the surface of the movable substrate 4 having the light-emitting diode 2 so as to exist above the light-emitting part of the light-emitting diode 2.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reflective vest worn over work clothes for workers working on a road at night to work safely, and particularly to a light emitting diode and wiring when the body is moved when worn. The present invention relates to a self-luminous device configured to efficiently direct light of a light emitting diode in a vertical direction without peeling off.

[0002]

2. Description of the Related Art Conventionally, in order to ensure the safety of people working on a road at night, a reflective vest in which a light emitting diode is attached to a movable wiring and a surface of a movable substrate wiring are worn over work clothes. There was a reflective vest fitted with a light emitting diode. Structurally, the wiring with the light emitting diode installed on the front surface is sewn on a mesh-like fabric with a tape-like material sandwiched between a reflective material on the surface and a material such as vinyl chloride on the back surface to form a vest. I was Alternatively, a wiring with light emitting diodes installed on the surface was installed under a tape-like material of a material such as reflective material on the front surface and vinyl chloride on the back surface, and it was sewn on a mesh-like fabric to form a vest. . In addition, a transparent transparent resin window is provided in the reflective material disposed on the light emitting diode in accordance with the light emitting portion of the light emitting diode.

[0003]

This has the following disadvantages. (A) Since the reflective vest is worn by the worker, the wiring is bent or twisted by the movement of the body, and the joint between the wiring and the light emitting diode may be separated. (B) Since the light emitting diode is installed on the surface of the wiring,
The junction between the light emitting diode or the wiring and the light emitting diode became uneven, and the reflective material portion became wrinkled, and the appearance was poor. In addition, since the light emitting diode and the joint between the light emitting diode and the wiring are on the surface, the joint between the light emitting diode and the wiring may be damaged by an external force that may collide during operation. (C) Since light escapes to the side of the light emitting diode,
The light emitted from the light emitting section cannot be effectively emitted in the vertical direction. The present invention has been made to eliminate these disadvantages.

[0004]

In order to eliminate the above-mentioned drawbacks,
The present invention provides a method for conducting electricity to the lower surface of a movable substrate (4).
Two twisted wires (5) are provided, and a hole (13) of an appropriate size is provided between the two twisted wires (5) for conducting the electricity. The back surface of the movable substrate (4) is joined to the twisted wiring (5) by soldering or the like so that the light emitting portion of the light emitting diode (2) is exposed to the surface of the movable substrate (4) in the hole (13). The gist of the invention is that a hard plate (9) made of resin or the like is joined to the bottom surface with an adhesive or the like to protect the joint. Further, on the upper surface of the movable substrate (4) having the light emitting diode (2), a hemispherical transparent resin (1) having a flattened vertex is placed on the light emitting part of the light emitting diode (2). And joined to the reflective material (3). The present invention is a self-luminous device having the above configuration.

[0005]

According to the above construction, even when an operator wearing a reflective vest incorporating a light emitting diode performs an operation of moving his body, the joint between the light emitting diode and the wiring is not twisted and the joint is separated. Can be reduced. Further, by providing a hemispherical transparent resin having a flat top on the upper surface of the light emitting diode, light from the light emitting diode can be efficiently emitted to the outer surface of the reflective tape, and visibility is improved.

Embodiments of the present invention will be described below. (B) On the back surface of the movable substrate (4) having an appropriate length, two twisted wirings (5) for passing electricity of an appropriate length are provided.
In order not to short-circuit the electrodes, a protective sheet (6) is placed on the bottom surface of the movable substrate (4) provided with wiring on the back surface. (B) A hole (13) of the same size as the light emitting portion of the light emitting diode (2) is formed between the two twisted wirings (5) of the movable substrate (4) for conducting electricity. 4) connection between the wiring (5) and the electrode (8) of the light emitting diode only on the protection sheet (6) provided on the protection sheet (6) and covering the wiring portion next to the hole (13). A mouth (12) is provided. (C) The light emitting diode (2) is arranged in the hole (13) of the movable substrate so that only the light emitting portion comes out of the surface of the movable substrate (4), and the electrode (8) of the light emitting diode is connected to the movable substrate ( 4) Join to the twisted wiring (5) from the back surface with solder or the like. (D) In order to protect the joint, a hard plate (9) of an appropriate size such as resin is joined to the lower part of the joint with an adhesive or the like. (E) On the upper surface of the movable substrate (4) having the light emitting diode, a hemispherical transparent resin (1) having a flattened apex is placed on the light emitting portion of the light emitting diode (2). At the same time, it is bonded and provided on the reflection material (3). The present invention has a structure as described above, and is sewn on a reflective vest or work clothes to improve visibility for a person working on a night road, and FIG. It is. To attach to the reflective vest, a suitable length of the movable substrate (4), on which the light emitting diode (2) is attached to the wiring (5) having the above configuration, is placed on the mesh-like fabric (7). Place a reflective material (3) of the same length provided with a hemispherical transparent resin (1) with flattened vertices,

[0007]

In the self-luminous device according to the present invention, the movable substrate (4) on which the light emitting diode (2) is mounted and the hard plate (9) made of resin or the like are integrated. This solves the problem that the joint portion between the wiring (5) and the light emitting diode (2), which is caused by torsion or impact when used, peels off.
