Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a flexible electroluminescent lamp, and more particularly to an electroluminescent lamp for illuminating a fishing float whose light emitting surface is spirally shaped or visible from all sides.

Conventionally, when fishing at night, you could not see the float, so you attached a bell to the end of your fishing rod and relied on the sound of the bell. Due to the inconvenience, auxiliary light sources such as flashlights were used.

For this reason, visual electric floats have been put into practical use in which a small battery is inserted into the float body, and a light bulb or LED light source is attached to the tip of the float to light up.

However, light bulbs and LEDs are point light sources, which are difficult to see and can be mistaken for other light sources.

Furthermore, these light sources have a drawback of short battery life due to their high current consumption.

The present invention has been proposed in view of the above, and provides a compact electroluminescent lamp for fishing that can be seen from all sides by using an electroluminescent lamp that is a surface light source and consumes little power.

The electroluminescent lamp for fishing according to the present invention uses an electroluminescent element shaped like an elongated tape, which is shaped into a cylindrical spiral.

Therefore, it is possible to obtain an electroluminescent lamp which is small in size, has a light emitting surface that emits light in a radial direction, and is suitable for illuminating a long and narrow fishing float.

Embodiments of the present invention will be described in detail below with reference to the drawings.

1 and 2 show a tape-shaped electroluminescent element 1 used in the fishing electroluminescent lamp of the present invention.

In the figure, 2 is a light emitting layer, which is a thin film (~50μ It can be obtained by cutting the tape into long and thin tapes.

3 is a transparent conductive film connected to both sides of the light emitting layer 2, 4 is a thermoplastic resin film, and 5 and 6 are electrode leads.

To manufacture the electroluminescent device 1 having the structure, first, tin oxide, indium oxide, etc. is vapor-deposited on a resin film 4 made of polyester, trifluoroethylene, etc., and then oxidized to produce a transparent conductive film. .

The tape-shaped luminescent layer 2 and the electrode leads 5 and 6 formed into the thin film are inserted onto this film as shown in the figure, and the film is easily manufactured by hot pressing from both sides.

Although this electroluminescent device 1 can be used as an illumination light source for a fishing float, it has the drawback that it does not emit light from the side surface of the light-emitting layer 2 and cannot be seen from the side surface.

Figure 2 shows 10 electroluminescent lamps for fishing that have improved this drawback.
The elongated tape-shaped electroluminescent device 1 shown in FIG. 1 is spirally wound to form a cylindrical shape.

An electroluminescent lamp 10 having a curved structure includes a tape-shaped light emitting element 1.
Although not shown, it can be easily shaped by spirally winding it around a cylindrical jig and heating or shaping it.

What is particularly noteworthy here is that because the elongated tape-shaped electroluminescent element 1 is wound spirally, the stress at the time of winding is less than that of a wide flat electroluminescent lamp that is cylindrical. It becomes smaller and can be reduced to a small diameter.

FIG. 4 shows another embodiment of the present invention, showing an electroluminescent lamp 20 having a longer winding interval than the electroluminescent lamp 10 according to the embodiment of FIG.

Compared to the electroluminescent lamp of the previous embodiment, the electroluminescent lamp 20 having a curved structure has a luminescent layer 2 of an electroluminescent element 1 formed by winding in a predetermined manner.
The stress between the transparent conductive film 3 and the transparent conductive film 3 is reduced, and there is an effect that peeling of the transparent conductive film 3 and the luminescent layer 2 and cracks in the luminescent layer 2 are less likely to occur.

Figure 5 shows the electroluminescent lamp obtained by this invention on a fishing float 3.
In the figure, 31 is a tapered upper container, and 32 is a hemispherical lower container, each of which is made of plastic and has a hollow shape, and is screwed together with a rubber packing 33 in between. has been done.

Reference numeral 34 is a known driving power source for an electroluminescent lamp, which is comprised of a battery, a booster circuit, a rectifier circuit, a discharge circuit, etc., and is housed in the lower container 31.

10. Reference numeral 20 denotes an electroluminescent lamp for fishing with a spirally wound light-emitting surface according to the present invention, which is housed in an elongated upper container 31 and whose lead-out lead is connected to a driving power source 34 so that it can be illuminated in all directions through the upper container 31. It is designed to emit light.

As described above, the present invention has a structure in which the tape-shaped light-emitting surface is spirally wound, so it can be seen from all sides and has an elongated cylindrical shape, which is suitable for lighting fishing floats. An electroluminescent lamp is obtained, which eliminates the drawbacks of conventional miniature lamps and LED light sources, extends battery life, and can be used as a surface light source.

In each of the above embodiments, light is collected from both sides of the light emitting layer, but the same effect can be obtained by using one transparent conductive film as a non-transparent electrode such as an aluminum film.
