Are arranged in a row, and a plurality of sub-controllers 20, 20, 20,..., Which are connected to the light-emitting units 10, 10, 10,. , And a main controller 30 connected to these sub-controllers 20, 20, 20,... And transmitting a synchronization signal for operating the sub-controllers 20, 20, 20,.
And And these light emitting units 1
Are grouped together, and the sub-controllers 20, 20, 20,... Operate in response to a synchronization signal from the main controller 30, and the light-emitting units 10, 10, 10,. Luminous bodies 11, 11, 11
.. Are configured to emit light sequentially according to the program.

The light emitting unit 10 used in the illumination device has a plurality of light emitting bodies 11, 11, 11,...
Are arranged in a line. The luminous body 11 may use a star ball (incandescent lamp) used in a general illumination device, or may use a light emitting diode. When a sphere is used, after the bulb is wired, it is waterproofed with an insulating coating so that it can be used outdoors. When a light emitting diode is used for the light emitting body 11, the holder 1 having flexibility like a synthetic resin is used.
Fixed to 2. When wiring the light emitting diodes, electrodes may be printed on the holder 12 and soldered.

The sub-controller 20 must program the lighting order of the light emitters 11 since the light emitters 11 of the light emitting unit 10 need to be turned on in a predetermined order in the case of a moving image or the like. ROM is set. When it is necessary to update the moving image data, the EP-ROM is set and the interface R
The data can be rewritten via S232C.

Further, the illumination device is shown in FIG.
The circuit configuration shown in FIG. A light-emitting unit 10 having a plurality of light-emitting bodies 11, 11, 11,...
Are connected to a sub-controller 20 that makes each light-emitting unit 10 emit light. The sub-controller 20 includes the light-emitting bodies 11, 11, 11,.
.. A controller 21 containing a ROM in which the order of emitting light according to the timing signal is programmed, and the light emitters 11, 1
And a driver section 22 for supplying a necessary drive current to 1, 11,....

Further, the sub-controller 20 is connected to the main controller 30 via a connection cable 23. The connection cable 23 is a cable for a synchronization signal, and a power cable (not shown) is separately connected from a commercial power supply. And since the connection cable 23 only sends a synchronization signal from the main controller 30 to the sub-controller 20, there is no need to separately wire the main controller 30 to each sub-controller 20.
All that is necessary is to connect each sub-controller 20 with one common connection cable 23.

The main controller 30 sends an operation timing signal to the sub-controller 20. The main controller 30 includes a controller unit having an oscillation circuit and a timing circuit (not shown) for the operation and a power supply unit for operating the controller unit. Have. Power supply unit is AC1 of commercial power supply
Since the voltage is converted from 00 V to a low DC voltage for operating the controller unit, and the controller unit consumes relatively little current, a small adapter or the like may be used.

In the illumination device having such a configuration, the light emitting units 10 are arranged in parallel to form a panel type illumination device such as an electric bulletin board, and the light emitting unit 10 can be bent freely. Alternatively, a three-dimensional display having a conical three-dimensional shape can be used. In any case, a robust framework is not required, and the wiring is simply connected between each sub-controller 20 and the main controller 30 with a single cable, so that it can be set up and operated with very little effort. is there.

Next, an embodiment of the illumination device configured as described above will be described. Illumination device A shown in FIG. 3 is obtained by forming the illumination device of the present invention into a panel type. In the illumination device A, the light emitting units 10 are mounted side by side along a frame 12 having a desired size. The wiring is to connect the respective sub-controllers 20 to the main controller 30 by connecting with a single connection cable 23 for a synchronization signal.

In the illumination device A configured as described above, it is not necessary to attach each of the light emitters 11 to the frame 12 and it is not necessary to wire each of the light emitters 11. Therefore, the illumination device A is installed. The operation in the case can be greatly reduced. Since the sub-controller 20 contains a pre-programmed ROM, it is possible to sequentially emit the light-emitting members 11 and display a moving image such as an electric bulletin board by a synchronization signal of the main controller 30. Advertising and expression are possible.

The illumination device B shown in FIG.
Is a line type illumination device formed in a conical shape. This illumination device B
Is, for example, the fir tree of the Christmas tree, or
A plurality of light emitting units 10 are attached along a conical frame. When the sub-controller 20 is located on the lower end side, the wiring becomes easier and the labor can be saved.

The illumination device B configured as described above has a conical shape as a whole, and is different from the conventional Christmas tree illumination in that the illuminators 11 are not only turned on and off but also are illuminated according to a pre-programmed order. Can be turned on and off, so that the light-emitting body 11 can be turned on and off so as to rotate as a whole, or from top to bottom or from bottom to top. Moreover,
For example, an image of Santa Claus or a reindeer can be expressed in the illumination device B, and the image can be moved.

The illumination device C shown in FIG.
Is a line type illumination device, which is cross-linked to street trees on both sides of a road. Since the illumination device C only bridges the light unit 10 between trees over a road, it is not necessary to attach the light emitters 11 one by one. Also, the wiring between the sub-controller 20 and the main controller 30 can be achieved by simply extending the line for the synchronization signal over the street tree.

The illumination device C configured as described above can display, for example, a half-way flow from the center of the road in the traveling direction of the vehicle, thereby facilitating the smooth traveling of the vehicle and at the same time as the road at night where the scene is scenic. It enhances the scenery of the city, gives the streets a gorgeous look, and greatly contributes to the revitalization of the surrounding shopping streets.

Further, the illumination device of the present invention comprises:
It is needless to say that the present invention is not limited to the above-described embodiment, but various embodiments are possible within the scope of the claims. For example, if the illumination device is reduced in size and weight, it can be attached to a stage costume, and its surprisingness, novelty, or variety of expression is exhibited to enhance the stage effect. When the illumination device is increased in size, it is used for an outdoor stage at an event venue or the like, and enhances the effect especially at night.
Furthermore, since this illumination device is excellent in temporary installation, it can be easily assembled as an emergency light signage device in a disaster area or the like, and can provide necessary information to a victim.
