In this conventional example, as shown in FIG. 4, a transparent soft synthetic resin sheet material is used for the inner surface. A retro-reflecting material 7 having a minute prismatic reflecting surface formed on it and a white lining 8 are overlapped, and both sides are double-welded with a high-frequency sewing machine, and a backing cloth 11 is superposed. Both edges are covered with a bias tape 12, and a sewing thread 13 is sewn between the two welding lines 9 to prevent moisture from entering the reflective tape 10 through the seams.

The reflective tape 10 has the surface side of a soft synthetic resin tape on which fine glass balls are adhered,
A reflective tape covered with a transparent soft synthetic resin tape for preventing water wetting is also used.

Reference numeral 5 denotes a light emitting diode. As shown in FIG. 5, an LED harness in which a plurality of light emitting diodes 5 are connected to two power supply lines 14 at predetermined intervals is provided on the left and right sides as shown in FIG. Front portion 2a and subsequent rear portion 2

Attached, and insert the tip of the light emitting diode 5 with the washer 20 fitted from the back side into the stopper 19 to attach the adhesive tape 2
1 fix the LED harness to the back of the reflective tape 10,
The back cloth 11 is sewn via the bias tape 12 to fabricate a reflective / light emitting tape material for the front portion a and the subsequent rear portion 2b.

[0008]

In the conventional LED safety vest and LED light emitting band, since the light of the light emitting diode is concentrated in the optical axis direction by the condensing action of the lens, the brightness when viewed from the optical axis direction is high. Although the visibility is improved, there is a problem that the visibility when viewed from the lateral direction of several tens of degrees from the optical axis is significantly reduced.

The present invention has been made to solve the above-mentioned problems, and enhances the visibility when viewed from the lateral direction without impairing the visibility when viewed from the optical axis direction. The purpose is to obtain the specified LED safety vest and LED emission band.

[0010]

According to the present invention, a plurality of through holes are formed in a reflection tape, and the tip portions of the light emitting diodes of the LED harness are inserted into the through holes from the back surface side, respectively. A washer-shaped light diffusing member is fitted into a portion protruding from the reflection tape, and is fixed to the reflection tape with an adhesive so as not to transmit water.

[0011]

1 is a sectional view of a reflective tape according to Embodiment 1 of the present invention, which corresponds to FIG. 4 of a conventional example, and FIG. 2 is a partially enlarged sectional view showing a mounting state of a light emitting diode. 4, the same reference numerals as those in FIG. 4 indicate the same parts. In the figure, the through hole 10a formed in the reflective tape 10 is formed to have the same diameter as the light emitting diode 5 or a slightly smaller diameter. 22 is a washer-shaped light diffusing member formed of a synthetic resin having a light-scattering / transmitting property, 22a is a through hole thereof, and 23 and 24 are adhesives.

In the mounting structure of the light emitting diode 5 according to the first embodiment, the front end portion of the light emitting diode 5 in which the washer 20 is fitted is inserted into the through hole 10a of the reflective tape 10 from the white lining 8 side, and the light emitting diode 5 is transparent. An adhesive 23 is applied to the reflection tape 10 around the portion protruding forward from the hole 10a, and the through hole 22a of the washer-shaped light diffusing member 22 is fitted into the light emitting diode 5 and pressure-bonded to prevent water from passing through. Then, the adhesive 24 is applied from the side of the white lining 8 of the reflective tape 10 so that the reflective tape 10 and the light emitting diode 5 are adhered to each other, and after the adhesives 23 and 24 are dried, the lining fabric 11 is attached to the bias tape 12. The reflective / light emitting tape material for the front portion 2a and the rear portion 2b is sewn through via the.

Since the process of sewing the LED light emitting band 1 shown in FIG. 1 is the same as that of the conventional example, the description thereof will be omitted.

In the LED light emitting band according to the first embodiment having such a structure, when the light emitting diode 5 is turned on, the light emitted from the light emitting point 5a of the light emitting diode 5 in the optical axis direction is caused by the lens at the tip. The light that is condensed and emitted laterally from the light emitting point 5a is scattered in the washer-shaped light diffusing member 22 and the entire light diffusing member 22 is illuminated brightly. It is much larger than the conventional dot-like one, and the visibility when viewed from the optical axis direction is further improved, and the visibility when viewed from the lateral direction of several tens of degrees from the optical axis is also significantly improved.

[0015]

As described above, according to the present invention, the visibility in the optical axis direction during use is further enhanced, and the visibility in the lateral direction of several tens of degrees from the optical axis is significantly improved. There is an effect that the LED safety vest and the LED emission band can be obtained.
