BEST MODE FOR CARRYING OUT THE INVENTION Next, embodiments of the present invention will be described. First, an outline of an air tent in which the light production device of the present invention is installed will be described with reference to the sectional view of FIG. 9 and the partial sectional perspective view of FIG. 10. As shown in FIG. 9, this air tent 4 is an air tent having an air-filled membrane structure, and constitutes the roof of the stadium 2 in this embodiment. Around the ground 6, eight assembly columns 8 (only two are shown in the figure) are erected at substantially equal intervals, and a ring truss 10 is arranged on the ground 6 to surround the ground 6. Has been done.
A roof is formed on the outside of the ring truss 10 by a ceiling film 12 supported by a predetermined frame.

The air tent 4 is annular when viewed from above,
In this embodiment, the opening 3 is formed at the center. The air tent 4 comprises an outer membrane 4a made of, for example, Teflon (corresponding to the outermost membrane) and an inner membrane 4b made of, for example, Teflon (corresponding to another membrane). An air chamber 14 is formed between them. Air is fed into the air chamber 14 by the blower 5 from the air supply port provided in the peripheral portion of the air chamber 14 through the blower pipe 7, and as a result, the inside of the air chamber 14 has an appropriate internal pressure P. As a result, the air tent 4 expands and forms a shape as shown in FIGS. The air chamber 14 formed by the membranes 4a, 4b is virtually impossible to keep completely airtight. Therefore, in order to supplement the air leaking from the air chamber 14,
An appropriate amount of air is constantly blown into the air chamber 14 by the blower 5 so that the shape of the air tent 4 is maintained.
Since neither of the films 4a and 4b is colored with paint or the like, and light passes through these films, the light is always taken through the air tent 4.

The opening 3 of the air tent 4 is shown in FIG.
As shown in 0, pulling rings 16a and 16b are arranged. The pull ring 16b is the pull ring 1
6a are arranged above the 6a in a concentric circle with respect to the pulling ring 16a, and the two pulling rings 16a, 16a
b is connected by a bundle 16c made of steel pipe.

The pull ring 16a and the ring truss 10
The inner peripheral edge of the 50 is radially arranged at a predetermined angular interval.
It is connected by a cable 18a of about this length, and the pulling ring 16a is pulled by an appropriate cable tension. The membrane 4b is supported by these cables 18a. The pull ring 16b and the inner peripheral end of the ring truss 10 are also connected by about 50 cables 18b radially arranged at a predetermined angular interval, and an appropriate cable tension is given. These cables 18b prevent the membrane 4a from expanding excessively upward.

Next, the periphery of the air tent 4 directly related to the present invention will be described in detail with reference to FIG. FIG.
FIG. 12 is a partial cross-sectional view showing a portion A of FIG. 11 in an enlarged manner. Between the film 4a and the film 4b forming the air tent 4, two films 4c and 4d, which are ring-shaped in plan view and are transparent and are made of, for example, synthetic resin, are connected to each other, as shown in FIG. An air chamber 14a is formed between the membranes 4c and 4d. A plurality of air supply ports 20a communicating with the inside of the air chamber 14a are provided at predetermined locations around the air chamber 14a. On the other hand, a plurality of exhaust ports 20b communicating with the air chamber 14a are formed at predetermined locations around the air chamber 14a on the side of the opening 3 of the air tent 4. A blower pipe 22a is connected to the air supply port 20a, and a blower pipe 22b arranged inside or outside the air tent 4 is connected to the exhaust port 20b. Although the air chamber 14a is divided into upper and lower parts by the air chamber 14a, air is supplied from the blower 5 to the vertically divided parts of the air chamber 14 to maintain the shape of the air tent 4.

On the other hand, the bead supply equipment 24 shown in FIG. 2 is installed at a predetermined position around the ground 6 shown in FIG. This bead supply facility 24 is used for the bead tank 2.
6, a blower 28, dampers 30 and 32, and the like. The bead tank 26 (corresponding to a tank) accommodates innumerable red beads 40 that transmit light as an example in this embodiment. As the beads 40, hollow plastic balls colored red, styrofoam colored red, or the like can be used. The size of the beads 40 may be about 5 to 20 mm in diameter. In addition, in the embodiment, the beads 40 correspond to a small and lightweight colored body that is movable and colored by the flow of air, but the structure of the colored body is not limited to such a bead 40. The discharge port 26b of the bead tank 26 is connected to the suction port 28a of the blower 28 by a predetermined pipe 34 through the damper 32.
It is connected to the. On the other hand, the supply port 2 of the bead tank 26
6a is the blower pipe 2 through the pipe 36 and the damper 30.
2b. In addition, the discharge port 28 of the blower 28
b is connected to the blower pipe 22a.

The dampers 30 and 32 are beads 40, respectively.
And electrically driven blades 30a, 32 for closing the air passages
a. As shown in FIG. 3, innumerable holes 300 each having a diameter smaller than that of the beads 40 are formed in each of the blades 30a and 32a. The state in which the blades 30a and 32a block the passage of the beads 40 and the air (that is,
In the closed state of the damper), only the air is absorbed by the dampers 30, 32.
Part of the beads 40 while the blades 30a, 32a
In the state where the air passage is not closed (that is, the damper is open), both the beads 40 and the air can pass through the dampers 30, 32. In this embodiment, the blower pipe 22a and the pipe 34 constitute a first pipe, the blower pipe 22b and the pipe 36 constitute a second pipe, and the dampers 30 and 32 respectively form the first and second pipes.
Filters are configured.

With such a structure, when performing various shows on the stadium 2, for example, when the air tent 4 is colored in order to produce a light effect, the electric damper 32 conducts a predetermined electric current. The electric damper 30 is closed by applying a predetermined electric current. In this state, when the blower 28 is started, the air flows from the blower to the air chamber 14 of the air tent 4 in the blower pipe 22a.
It moves toward a, passes through the air chamber 14a, and reaches the damper 30 from the blower pipe 22b. Here, damper 30
Although it is in a closed state, air can pass therethrough, so that the air that has reached the damper 30 enters the bead tank 26 through the pipe 36. As a result, the beads 40 stored in the bead tank 26 are pushed out and reach the damper 32 through the pipe 34. Since the damper 32 is in the open state as described above, the beads 40 pass through the damper 32 and enter the air chamber 14a from the air supply port 20a through the blower 28 and the blower pipe 22a.

In this state, the beads 40 have not accumulated in the air chamber 14a, so that the beads 40 are discharged from the exhaust port 20.
Since it is discharged from b and the damper 30 is in a closed state, it accumulates in the blower pipe 22b. The beads 40 discharged from the bead tank 26 in this manner are provided in the blower pipe 22b.
When the air is gradually accumulated inside the air duct and the bead 40 is filled with the beads 40, thereafter, the air is accumulated inside the air chamber 14a of the air tent 4, and finally, as shown in FIG. It is filled. In this state, the blower 28 is stopped. Since the beads 40 are made of light-transmissive red plastic, the outside light that passes through the air tent 4 and is incident is colored red, so that everything under the air tent 4 is colored red by this light. Become.
The air tent 4 looked up from below is also colored red. In this way, everything in the large space under the air tent 4 is colored, and the entire vast ceiling is colored, so that the effect of production is extremely large.

On the contrary, when the coloring is eliminated, the electric damper 32 is energized for a predetermined amount to be in the closed state contrary to the above case, while the electric damper 30 is energized for a predetermined amount. In contrast to the above case, the open state is established. When the blower 28 is started in this state, the beads 40 accumulated in the air chamber 14a are pushed out by the air from the blower 28, pass through the damper 30 in the open state, and enter the bead tank 26. Even if the beads are not accumulated in the bead tank 26 and are discharged from the discharge port 26b, the damper 32 is in the closed state, and is blocked by the damper 32 and does not move further. Therefore, bead tank 2
Beads 40 gradually accumulate in 6 and bead 40 is completely removed from air chamber 14a of air tent 4. As a result, the air tent 4 is in the original transparent state, and coloring is eliminated.

As described above, in this embodiment, the red transparent beads 40 are filled in the air chamber 14a formed in the air tent 4, so that the red light is easily incident on the entire large space under the air tent 4. And the entire ceiling can be colored.

Next, the second embodiment will be described. This embodiment is different from the above-mentioned embodiment in that an air chamber for filling beads is formed only by adding one film. FIG. 5 is a sectional view corresponding to FIG. In the air tent 4'of this embodiment, a single film 4e formed by joining a transparent film made of, for example, a synthetic resin, which is annular in plan view, between the films 4a and 4b is as shown in FIG. And an air chamber 14b is formed between the membrane 4a and the membrane 4e. The air chamber 1 is provided at a predetermined position around the air chamber 14b.
A plurality of air supply ports 20a communicating with the inside of 4b are provided. A plurality of exhaust ports 20b communicating with the air chamber 14b are also formed at predetermined locations around the air chamber 14b on the side of the opening 3 of the air tent 4. A blower pipe 22a is connected to the air supply port 20a, and a blower pipe 22b is connected to the exhaust port 20b.

In this embodiment, the bead supply equipment 24 is used as it is as the bead supply equipment, and the description thereof is omitted here. The blower tubes 22a and 22b are
Similar to the case of the above-described embodiment, the blower 28 is connected to the discharge port 28b and the damper 30, respectively. The operation for coloring the air tent 4 is the same as that of the above-described embodiment, and the beads 40 housed in the bead tank 26 are blown into the air chamber 14b by the blower 28 and filled in the air chamber 14b. It As a result, the outside light is colored red by the filled beads 40 and enters under the air tent 4, and the ceiling itself of the air tent 4 is also colored red. When the coloring of the air tent 4 is to be eliminated, the beads 40 in the air chamber 14b are pushed out by the air from the blower 28 and stored in the bead tank 26 in the same manner as described above. As a result, outside light passes through the air tent 4 to reach the inside, and coloring is eliminated. The air chamber 14b
It is optional to provide a pipe or a valve for feeding the air from the blower 5 to the.

Next, a third embodiment will be described. This embodiment differs from the first embodiment (or the second embodiment) in that the bead supply equipment 25 is used instead of the bead supply equipment 24. That is, as shown in the configuration diagram of FIG. 6, this bead supply facility 25 includes three bead tanks 2.
61, 262, 263, and each of the tanks contains beads 401, 402, 403 of red, blue, and yellow colors.

Discharge port 2 of each bead tank 261-263
6b are tank connecting pipes 341, 342, 343, respectively.
(Corresponding to the first tank connection pipe) is connected to each input port 410a, 410b, 410c of the connection device 410, while
The suction port 28a of the blower 28 is connected to the output port 410d of the connection device 410 through a pipe. Connection device 4
10 is configured using a plurality of electric three-way valves,
It has a function of selectively connecting any one of the tank connection pipes 341 to 343 to the suction port 28 a of the blower 28. In the middle of the tank connecting pipes 341 to 343, the electric dampers 321 to 323 (corresponding to the first filter) of the same type as the damper 32 described above are inserted. The outlet 28b of the blower 28 is connected to the air supply port 20a of the air chamber 14a of the air tent 4 shown in FIG. 1 through a blower pipe 22a (corresponding to a first pipe).

On the other hand, the supply ports 26a of the bead tanks 261 to 263 have tank connecting pipes 361, 362 and 3, respectively.
63 (corresponding to the second tank connecting pipe) is connected to each output port 412a, 412b, 412c of the connecting device 412, and the input port 412d of the connecting device 412 is the air chamber 14a of the air tent 4 shown in FIG. Blower pipe 22b at the exhaust port 20b
(Corresponding to the second pipe). The connection device 412 is also configured by using a plurality of electric three-way valves, for example, and has a function of selectively connecting any of the tank connection pipes 361 to 363 to the blower pipe 22b. The damper 3 described above is provided in the middle of each of the tank connecting pipes 361 to 363.
Electric dampers 301 to 303 (corresponding to a second filter) of the same type as 0 are inserted.

Each of the dampers 301 to 303 and 321 to 323 is provided with electric beads 30a and 32a for closing the beads 40 and the air passage. These feathers 3
As shown in FIG. 3, innumerable holes 300 having a particle size smaller than that of the beads 40 are formed in the holes 0a and 32a.

In this structure, for example, when the air tent 4 is colored red, the connection device 410 is energized to connect the tank connection pipe 341 to the blower 28, while the connection device 412 is energized to connect the tank. The pipe 361 is connected to the blower pipe 22b. Then, the damper 321 is opened and the damper 301 is closed to start the blower 28. As a result, as in the case of the first embodiment, the red beads 401 are sent from the bead tank 261 into the air chamber 14a, and the air tent 4 is colored red. When the coloring is eliminated, the dampers 321 and 301 may be set in the opposite states to the above, and the blower 28 may blow the air.

When the air tent 4 is colored blue, the tank connecting pipe 342 is connected to the blower 28 by the connecting device 410, while the tank connecting pipe 362 is connected to the blower pipe 22b by the connecting device 412. Then, the damper 322 is opened and the damper 302 is closed to start the blower 28. As a result, the blue beads 402 are sent from the bead tank 262 into the air chamber 14a, and the air tent 4 is colored blue. When the coloring is eliminated, the dampers 322 and 302 may be set in the opposite states to the above, and the blower 28 may blow the air.

When the air tent 4 is colored yellow, the connection device 410 connects the tank connection pipe 343 to the blower 28, while the connection device 412 connects the tank connection pipe 363 to the blower pipe 22b. Then, the damper 323 is opened and the damper 303 is closed.
The blower 28 is started. As a result, yellow beads 403
Are sent from the bead tank 263 into the air chamber 14a, and the air tent 4 is colored yellow. When the coloring is eliminated, the dampers 323 and 303 may be set in the opposite states to the above, and the blower 28 may blow the air.
As described above, in the third embodiment, the air tent 4 can be colored by switching to a plurality of colors instead of one color, and a more dramatic effect can be obtained by light.
