FIG. 5 is a plan view showing the sky arrangement state of the irradiation unit U,
FIG. 6 is a plan view showing an arrangement of an atmosphere lighting mechanism, FIG. 7 is a block diagram showing a control mechanism, and FIG. 8 is a drawing showing a display unit of the artificial sky device of the present invention.

 This will be described with reference to FIGS. 1 and 2.

The artificial sky device of the present invention is provided indoors, and an irradiation unit U and an artificial sun S are arranged in a sky dome D.

In the measurement room 6 provided outside the sky dome D, a control device is arranged so as to enable remote control.

The printer 1, the artificial sun console 2, the lighting console 3, the electric equipment control panel 4, the indoor enlarged monitor television 5, and the like are arranged inside the measurement room 6. In addition, a dome chamber 8 having a sky dome D outside the measurement chamber 6 is provided, and the sky dome D is arranged in the dome chamber 8.

When these control operation devices are arranged in the sky dome D, the inside of the sky dome D becomes narrow, and the light from the irradiation unit U or the artificial sun S is irregularly reflected, or emitted from the indoor enlarged monitor television 5 or the like. Since there is a possibility that the brightness may be different from the sky luminance set by the irradiation unit U due to the light beam, all the control devices are arranged outside the sky dome D.

Next, the computer wiring state will be described with reference to FIG.

A control computer 7 is arranged on the wall surface of the dome chamber 8, and the control computer 7 controls 853 irradiation units U. Since the irradiation units U are symmetrically configured in the east and west, the control computer 7 controls 427 sets, and one set of two right and left irradiation units U
Are controlled to emit the same luminance.

Just because the irradiation unit U at the position directly above the sky cannot be left-right symmetric, it is one set as a control set,
It is configured to adjust the luminance of one irradiation unit U.

The wiring is made from the control computer 7 to these 853 irradiation units U.
Is arranged along the outer periphery of the frame of the sky dome D.

Then, the center line 0-0 shown in FIG. 4 indicates the center position of the sky dome D, and the artificial sun S rising above the center line 0-0 to the position of the true sky is provided. The irradiation unit U is 426 symmetrically with respect to the center line 0-0.
They are arranged east and west one by one.

 Next, FIGS. 5 and 6 will be described.

In FIG. 5, the irradiation unit U in the sky dome D
Is arranged. An artificial sun passing gap 10 is formed on the south side of the position of the center line 0-0, and the artificial sun S driven by the artificial sun driving device M moves up and down in the artificial sun passing gap 10.

Further, at a lower position in the sky dome D, a staging light 11 for 45
The tables are arranged. The production spotlight 11 has 15 control circuits for dimming, and the brightness of the production spotlight 11 is adjusted by the 15 control circuits.

The position of the effect spotlight 11 will be described with reference to FIG.

FIG. 3 is a sectional view of the sky dome D taken along the center line 0-0. The hemispherical sky dome D is a portion above the horizon level LL, and the horizon level LL
The lower part is a part below the horizon that does not constitute the sky part. A partition 17 is provided circumferentially below the horizon, and 45 effect spotlights 11 are arranged outside the partition 17 and between the inner surface of the sky dome D.

The effect spotlight 11 illuminates with blue and red light to produce an effect scene from a sunrise to a blue sky and a sunset.

853 irradiation units U provided on the inner surface of the sky dome D
Are all configured to irradiate white light, so that the brightness distribution of the sky can be expressed, but the blue sky cannot be expressed. Similarly, since neither sunset nor sunrise can be expressed, in order to create such a state, the state of the luminance illuminated by the white irradiation unit U is colored with blue and red to produce the effect. .

Although 45 spotlights 11 for the effect are arranged,
There are 15 dimming circuits, 45 units each covered with blue, red and white filters, 15 units each for blue directing spotlights, red directing spotlights, white directing spotlights By illuminating one of the three sets, the blue sky, sunset / sunrise, and daytime white are expressed.

In FIG. 3, a rotary model table 14 is arranged at a central position in the sky dome D.

The rotary model table 14 is rotated on a horizon level LL by a rotation control drive mechanism N.

Since the artificial sun S moves only 90 degrees from the horizon to the center of the sky, the rotation of the rotary model table 14 creates a morning and an afternoon. At noon, she would be in the southern position, and in the afternoon she would gradually move westward. Then, when the state of the day is expressed, the rotating model stand 14 is returned to the original position in the morning.

In FIG. 3, a house model H is disposed on a rotating model table 14, and a lift table 15 and a lift scissor mechanism 16 are configured so that the house model H can be easily adjusted and placed. I have.

Also, in the sky dome D, when the change in the sky brightness and the change in the artificial sun S for a day are observed, the sun only moves up and down by 90 degrees, and the brightness changes at the same position in the sky. Only if it does not move in the same way as the house model H on the rotating model stand 14, it is impossible to experience a state close to the state of movement of the day.

An experience chair 12 is provided that moves in the same manner as the model house H so that a viewer can experience this state. The experience chair
Reference numeral 12 is fixed to a part of the rotary model stand 14 by a chair supporting rod 13.

With this configuration, the experience chair 12 rotates together with the rotating model table 14, so that the sun rises from the east and sets in the west.

Next, referring to FIG. 8, the operation display section of the artificial sky device of the present invention will be described.

In the artificial sky device of the present invention, a sky lighting experiment,
It can perform solar radiation / shadow experiments, effect presentations, demonstrations, etc.

That is, in the sky lighting experiment, the artificial sun S was not moved up and down,
This is performed only by the irradiation of the irradiation unit U.

CIE Standard Clear Sky, Intermediate Sky, CIE Standard Cloudy Sky, Average Sky, etc., set by the International Commission on Illumination (CIE)
It is possible to radiate daylight brightness under certain conditions.

By placing the house model H in the standard sky state and measuring the lighting state of each part, a sky lighting experiment can be performed. The values measured in the sky lighting experiment can provide a lighting state of a standard model state that can be evaluated when designing a house or building.

Next, in the solar radiation / shadow experiment, the artificial sun S is also raised and lowered.

In other words, from a window in a certain place and facing a certain direction, what kind of solar radiation and shade can be obtained on a certain spring, summer, autumn and winter day,
You can simulate.

In the case of this solar radiation / shadow experiment, the state is created by specifying the month, day, and location, and specifying whether it is a continuous movement of one day or a fixed state of solar radiation / shadow for a certain time. You can do it.

With the movement of the artificial sun S, the irradiation unit U in the sky
Also changes by simulation every time.

Next, in the case of effect production, as described above, out of the 45 production spotlights 11, 15 of the three sets of filters, red, blue and white, are selected, and the dimming 15 circuits are used. By dimming, it is possible to create the ever-changing blue sky and the state of sunset and sunrise.

The effect spotlight 11 can also simulate continuously from sunrise to blue sky to sunset in conjunction with the simulation of the solar radiation / shadow experiment.

In the effect production, the artificial sun S is regarded as the moon, and by setting the moon altitude, azimuth and brightness,
With the brightness of the moonlit night, it is possible to create a moon scene or create a fully lit scene.

The demonstration is not an experiment to collect data, but a demonstration is given to the viewer by changing the CIE standard clear sky, the intermediate sky, the artificial sun S for the solar radiation / shadow experiment, and the sky brightness. You can do it.

(F) Effects of the Invention The present invention is configured as described above, and has the following effects.

First, by adjusting the brightness of all the 853 irradiation units U arranged on the inner surface of the sky dome D by simulation, a CIE standard clear sky or a CIE standard cloudy sky can be obtained. In the design of the above, by making a house model H, it is possible to obtain daylighting experiment data of a real state by simulation before a building is actually made. Therefore, at the time of designing a house or a building, daylighting data sufficient for evaluation. The standard data that can be obtained can be obtained.

Second, by setting the moon, day, and place, it is possible to simulate the artificial sun S and sky brightness at the same time, and perform an insolation / shadow experiment with a certain window. It is possible to reliably reproduce the state of infringement on the sunshine right of the existing houses around which is caused by the construction of certain houses and buildings.
