A decorative body 6 is connected to a drive shaft 4 which is reciprocally driven in the vertical direction by the drive mechanical body 2 via a connecting piece 5. This ornamental body is covered with a dome-shaped transparent cover body 7, and the flange portion 7a of the transparent cover body is in contact with the upper surface of the mounting plate 1 and is fixed by an adhesive or the like.

The structure of the ornament 6 will be described in detail below. The shape of the ornamental body 6 is shown in FIG. 2 in a developed manner. The upper portion of the base portion 6a is branched into a large number of strip-shaped ornamental pieces 6b ... And the driving power is supplied to the lower end portion of the base portion 6a. A pull-out terminal portion 6c is provided for this purpose.

The ornamental body 6 is composed of a flexible EL sheet in which EL elements are formed in a sheet shape, and an enlarged cross section is shown in FIG. That is, the light emitting layer 62 is formed on the transparent conductive film 61 as an example of the transparent electrode. The light emitting layer 62 is made of an ink containing a light emitting body containing an activator such as copper or a base in zinc sulfide and a high dielectric binder (cyanoethylated cellulose etc.) previously dissolved in a solvent.
It is printed and dried to form a layer. Next, the dielectric layer 63 is formed on the light emitting layer 62. The dielectric layer 63 is formed by printing an ink composed of barium titanate powder and a high dielectric binder previously dissolved in a solvent and drying the ink to form a layer. Furthermore, on this dielectric layer 63,
A back electrode 64 is formed. The back electrode 64 is formed by printing and drying a conductive paste made of carbon powder and a resin (acrylic or the like) dissolved in a solvent.

As an example of changing the emission color of the EL sheet,
In order to obtain a blue-green emission color, a luminous body containing zinc sulfide containing copper is used as a luminous body, and in order to obtain an orange emitting color, a luminous body containing zinc sulfide containing copper and manganese as a luminous body. In order to obtain a white emission color, a light-emitting body in which a light-emitting body containing zinc sulfide containing copper and manganese and a light-emitting body containing zinc sulfide containing copper is used as a light-emitting body. Further, in order to obtain EL sheets having different emission colors, fluorescent pigments or fluorescent dyes having different colors may be mixed in the emission layer.

As shown in FIG. 2, a lead-out terminal portion 6c is formed on the base portion 6a. The lead-out terminal portion 61a of the transparent electrode pulled out from the transparent electrode 61, the dielectric layer 63, and the back surface. It is composed of a lead-out terminal 64a of the back electrode pulled out from the electrode 64. Above the lead-out terminal 61a,
The same conductive paste as described above is printed to form the lead-out terminal electrode portion 61b of the transparent electrode. Drawout terminal 61
Lead wires 61c and 6 for supplying drive power from a drive circuit of an EL sheet (not shown) to a and 64a, respectively.
4c (shown in FIG. 1) is connected.

In order to make the base portion 6a of the ornamental body 6 cylindrical, a joint portion 6d is provided from the side of the base portion 6a. The base portion 6a is formed into a cylindrical shape by joining the joining portion 6d to the other side, and the decorative pieces 6b ... Are bent so as to be radially inverted so that the inner side is the outer side, and the inner surface of the transparent cover body 7 is formed. On the other hand, the decorative pieces 6b ...

Further, when the base portion 6a is formed in a tubular shape, the upper portion of the tubular shape becomes an opening, and therefore, the central ornament body 8 is provided so as to close the opening. The central ornamental body 8 has a disk shape and is formed of an EL sheet like the ornamental body 6. The connecting pieces 8a, 8a extend from opposite positions on the outer periphery of the central ornamental body 8, and at the tip of one of the connecting pieces, a lead-out terminal for the transparent electrode and a lead-out terminal for the back electrode are formed at the tip of one of the joining pieces, as in the ornament 6. Has been formed. The connecting piece 8a descends along the cylindrical inner surface of the decorative body 6 and is in contact with the base portion 6a. In the lead-out terminal portion 6c, the lead-out terminals 61a and 64a of the ornamental body 6 and the corresponding lead-out terminals of the central ornamental body 8 are electrically connected to each other, and the lead wires 61c are connected to the respective lead-out terminals. , 64c are supplied with drive power.

When drive power is supplied to the ornaments 6 and 8 through the lead wires 61c and 64c, the EL sheet emits light in each emission color. The ornaments 6 and 8 can also be configured to have different emission colors. Also, the decorative body 6,8
It is also possible to supply the driving power to each of them via separate lead wires. In addition, the brightness of the emitted light can be changed by changing the drive voltage or the drive frequency for driving both the ornaments. Further, by controlling the driving voltage and the driving frequency so that the driving voltage and the driving frequency gradually change, it is possible to obtain a decoration in which the brightness of the decoration gradually changes. In addition, it is possible to produce various effects by changing the combination of the color of emitted light and the brightness.

The drive shaft 4 is driven by the drive machine body 2,
For example, when it is reciprocally driven in the vertical direction, the decorative bodies 6 and 8 are reciprocally moved up and down through the connecting piece 5, and the decorative piece 6b ...
Moves up and down while being in contact with the inner surface of the transparent cover body 7.
Since different frictional force acts on each decorative piece 6b, each piece of light shines while moving non-uniformly, and for example, an image like the fluctuation of the sea bream on the seabed appears.

In addition, the drive shaft 4 can be driven so as to reciprocally rotate, and can also be driven so as to reciprocate vertically and at the same time reciprocally rotate, so that an interesting decorative object can be produced for each.

Although not shown, the EL sheet is usually sealed with a moisture-proof film, or a water catcher layer is formed on the back electrode to prevent the entry of water. Further, the shape of the ornamental body is not limited to the above, and various other shapes are applied.

[0019]

As described above, in the production decoration device of the present invention, the base body of the tubular EL sheet is connected to the drive shaft with the base body branched into a number of strip-shaped decoration pieces. Therefore, it is possible to move the decoration body in various ways by moving the drive shaft, and at the same time, it is possible to supply drive power to the EL sheet to cause it to emit light. It is possible to provide an effect decoration device having an extremely excellent effect in displaying the image. Further, by bringing the decorative piece into contact with the transparent cover body, it is possible to enjoy a special image caused by uneven movement of the decorative piece. Further, by providing the central portion decoration body, many effects can be achieved by various combinations.
