Further, in FIG. 3, (8) is a cylindrical connecting member made of, for example, an insulating resin material, and one end of which is shown in FIG.
As can be seen in, a terminal (9) of an electric wire (7) electrically connected to an electric power source (a) such as a storage battery or a solar power generator, a switch mechanism (b), an optical sensor (c) is provided. ing. Then, one end of the conductive plate (10) of the emission band main body (1) is slightly extended from the emission band main body (1),
This extension is butted against the terminal (9) of the electric wire (7).

Now turn on the switch of the switch mechanism (b).

In this way, the band-shaped light emitting band body (1) which emits band-shaped light can be processed into an appropriate shape and applied to light emission of articles for various purposes at night and the like.

For example, FIG. 4 shows a warning display board (A) provided on the shoulder of a road to indicate one-way traffic of the vehicle or that the road is curved, and "⇒" drawn on the warning display board (A). The luminous band main bodies (1) are arranged or cut in the same shape as the portion.

FIG. 9 shows a uniform (H) of a police officer or a construction worker to which the light emitting band main body (1) is attached, FIG. 10 is a contour portion of a curve mirror (I), and FIG. 11 is a railway. FIG. 12 shows a light emitting band main body (1) attached to a snowboard or a ski (K) on the opening / closing rod (J) of the circuit breaker.

However, as shown in FIG. 2, each of the emission band bodies (1) has a switch mechanism for energizing the reflective conductive electrode substrate (2) of the emission band body (1) only at night or in the dark. By providing (b), the light emitting band body (1) emits light continuously or by blinking at night or in the dark.

Further details of the structure of this embodiment will be made clear by referring to the manufacturing means of the emission band main body (1) below.

That is, FIG. 14 shows a tape-shaped substrate (6) made of a transparent insulating plastic material wound on one roll (21), and the luminous band main body (1) is on the other roll (22). It is shown that it is manufactured by being wound into a roll. The tape-like substrate (6) of transparent insulating material in this embodiment is about 0.005 inches thick and preferably 24 to 60 inches wide and 500 to 900 feet long.

(23) is a container for the conductive coating agent (4) which is indium-tin oxide, and is a transparent conductive coating agent having a thickness of about 400 angstroms upon contact with the tape-shaped substrate (6). (4) is applied to one side. In this case, the electrically conductive coating agent (4) must ensure an electrical insulation voltage with respect to the electrode substrate (2). Further, the viscosity is applied at about 700 CPS, and is cured by passing through an ultraviolet device (24) having a specific wavelength.

Next, the tape-shaped substrate (6) coated with the electrically conductive coating agent (4) is transferred to the supply device (25) for the light emitting element (3). This device (25) is a dry light emitting device (3) containing a source of fluorescent material, the device size of which does not exceed 400 mesh (up to 38 microns) when using zinc sulfide. Of course, it is possible to use the electroluminescent device (3) other than zinc sulfide, but the device diameter is most preferably about 400 mesh (38 microns), and the maximum device diameter is preferably about 50 microns or less.

Furthermore, the supply device (25) contains a device for creating an electrostatic field. Then, the electrostatic field causes the light emitting element (3) to be electrostatically attached or attracted onto the conductive coating agent (4). As a result, the light emitting element (3) is electrostatically adhered onto the conductive coating agent (4) so that large elements can be closely arranged side by side without being laminated. In other words, it must be spread evenly on the tape-shaped substrate (6) with a surface density close to 100% except for the gaps between the light emitting devices (3).

The zinc sulfide light-emitting element (3) has a polarity, and the direction of the electrostatically attached light-emitting element (3) changes from one element to an adjacent element on the tape-shaped substrate (6) surface. Have the same azimuth, which has the effect of increasing the luminous efficiency and increasing the light output density of the lamp surface during operation. Then, the tape-shaped substrate (6) is continuously moved to a curing device (26) such as an ultraviolet ray generator to move the light emitting element (3).
Is cured with a conductive coating agent (4) on a tape-shaped substrate (6).

Although not shown in detail in the drawings, it is advisable to further deposit a conductive coating agent (4) on the light emitting element (3) on the coating agent (4). Its typical thickness is at least about 0.0003 inches, which fits into the gap between the aligned light emitting elements (3) and completely surrounds the elements to firmly embed the light emitting element (3). Is. Moreover, the electrically conductive coating agent (4) has low hygroscopicity and is highly deformable, accumulates electrostatic energy, and enables high light emission output.

(27) is a metal vapor deposition apparatus for forming a typical metal layer, to which vapor deposited aluminum is supplied. Thus, on the coating material (4) or the light emitting element (3)
By forming a glossy reflective conductive electrode substrate (2) layer consisting of a vapor-deposited layer having a thickness of about 300 angstroms on top of it, the high purity of the vapor-deposited material contributes to the emission as a high gloss reflective conductive electrode. The output is increasing. After the above manufacturing process, the tape-shaped substrate (6) is put on the other roll (2).
In 2), the winding light emitting band body (1) is obtained. However, in this case, a suitable resin coating is also applied on the conductive electrode substrate (2) as required. Further, after the conductive electrode substrate (2) is vapor-deposited, the total thickness of the entire stack of the emission band main body (1) is about 0.007 inch.

The above-described manufacturing apparatus for the light emitting band main body (1) is suitable for mass production of panels, but in actual manufacturing, the insulating adhesive layer (4) and the surface thereof are arranged neatly and electrostatically attached. It is essential that the light emitting element (3) thus adhered is attached to the surface of the light emitting element (3) at an appropriate interval, and this is due to the flexibility of the entire light emitting band body (1) and is applied to various products. This is to make it easier.

That is, on the tape-shaped substrate (6) of the emission band main body (1), as shown in FIG. 14, the layers of the emission band main body (1) are provided with appropriate intervals (28), and this interval ( Two
8) The part will be cut. Further, as seen in FIG. 15, it is preferable to provide an appropriate gap (29) in the longitudinal direction of the conductive electrode substrate (2). By doing so, it is possible to obtain a light emitting band main body (1) having a narrow width or a short length, or conversely arranging them in the width direction to obtain a wide light emitting band main body (1).

As described above, the present invention can be applied to the light emission of a multipurpose article at night, etc., by processing the light emission band main body (1) manufactured in the shape of a band into an appropriate shape. Note that this invention emits visible rays when ultraviolet rays hit a solid fluorescent material, that is, the material absorbs the energy of light upon irradiation.
The light includes so-called “fluorescence”, which is a type of light that emits light having a different wavelength and stops when the irradiation is stopped.
