(b) Prior Art Artificial sky devices themselves have been well known. Depending on the illumination method of the artificial sky, there are several known types, including a reflective dome type, a transparent dome type, a direct irradiation dome type, and a mirror type.

However, although the reflective dome type has good reproducibility of the CIB standard cloudy edge sky, it is difficult to control the brightness, and the transmissive dome type and crosspiece type have good reproducibility of the CIE standard cloudy sky, but they cannot reproduce the clear sky. It is also difficult to adjust the brightness.

Furthermore, although there have been ancient artificial sky devices that irradiate light directly, no technology has been disclosed that simultaneously uses a computer to simulate the brightness adjustment of a large number of irradiation units placed in the sky and the adjustment of the position of an artificial sun. It is.

(c) Problems to be Solved by the Invention The present invention enables simulation of the actual sky brightness and movement of the sun by controlling the irradiation unit and the artificial sun that make up the sky, and furthermore, the sky brightness and the artificial sun can be simulated using a computer. The atmosphere lighting mechanism makes it possible to create sunrises, blue skies, and sunsets that cannot be expressed by the sun alone.

(d) Means for Solving the Problems The problems to be solved by the present invention are as described above. Next, the means for solving the problems will be explained.

By specifying the month, day, and time, the light of multiple irradiation units Ll placed all over the sky is automatically adjusted, and the artificial sun S, which rotates from the horizon to the center of the sky on one side of the artificial sky, is automatically raised and lowered. In the moving artificial sky device, a spotlight 11 for lighting the atmosphere is placed below the horizon level L-L of the sky dome D, and a blue, white, and red filter is applied to the spotlight 11 for lighting. In addition, the brightness is computer-controlled based on daily changes.

In addition, in the artificial sky atmosphere lighting mechanism, the spotlight 11 for effect located at the entrance opening of the sky dome D is configured mainly with a red filter, and the sunset light that is lit in the case of sunset is Seso) Y. Yuyake made Set Y movable.

In addition, in the artificial sky atmosphere lighting mechanism, a production spotlight 11 is arranged on the inner periphery of the sky dome D below the horizon level LL, and a production spotlight 11 is placed in a circle in the air conditioning duct, overlapping with the production spotlight 11. It is placed inside the circumference.

The figure is a diagram showing a display section of the artificial sky device of the present invention.

This will be explained with reference to FIGS. 7, 8, and 9.

The artificial sky device of the present invention is installed indoors, and an irradiation unit (U) and an artificial sun (S) are placed inside a sky dome (D).

Then, in the measurement room 6 set up outside the sky dome D,
A control device is installed to enable remote control.

A printer 1 is placed inside the measurement chamber 6.
, an artificial solar control console 2, a lighting control console 3, an electrical equipment control panel 4, an indoor enlarged monitor television 5, and the like. In addition, a dome room 8 is provided outside the measurement room 6 in which a sky dome D is placed.
A sky dome D is arranged within the dome chamber 8.

When these control operating devices are placed inside the sky dome D, the inside of the sky dome D becomes narrow, and the light rays from the irradiation unit U and the artificial sun S are diffusely reflected or emitted from the indoor enlarged monitor TV 5, etc. All of the control equipment is placed outside the sky dome D, since there is a risk that the sky brightness will be different from the sky brightness set by the irradiation unit U due to the light rays.

A control computer 7 is placed on the wall of the dome chamber 8, and from the control computer 7, 853 irradiation units are
-U is controlled. Since the irradiation unit U is configured symmetrically in the east and west, the control computer 7 controls 427fiJl, and IMi controls the two irradiation units U on the left and right so that they emit the same brightness.

The irradiation unit U located just above the sky cannot be left and right symmetrical, so there is only one control group.
It is configured to adjust the brightness of the two irradiation units U.

Wiring is made from the control computer 7 to these 853 irradiation units U.

The center line O-0 shown in FIGS. 2 and 3 indicates the center position of the sky dome D, and an artificial sun S is provided that rises above the center line 00 to the position of the true sky. . Also, the irradiation unit 1-U is symmetrically centered around the center line O-0.
There are 426 pairs arranged in east and west directions.

Next, FIGS. 2 and 3 will be explained.

In FIG. 2, the arrangement of the irradiation unit (U) inside the sky dome (D) is shown. An artificial sun passage gap 10 is constructed on the south side of the position of the center line 〇-〇, and an artificial sun S driven by an artificial sun driving device M moves up and down within the artificial sun passage gap 10.

In addition, at the lower position in the sky dome D, 45 performance spots 7) 11 are arranged inside the circumference of the sky dome D. The performance spotlight 11 is equipped with 15 control circuits for dimming, and the brightness of the performance spotlight 11 is adjusted by the 15 control circuits.

The position of the performance spotlight 11 will be explained with reference to FIG.

FIG. 1 shows a cross-sectional view of the sky dome D along the center line 0-O. The hemispherical sky dome D has a portion above the horizon level LL, and a portion below the horizon level LL does not constitute a sky portion but is below the horizon. A partition wall 17 is provided on a circumferential cane below the horizon line, and 45 spotlights 11 for performance are arranged between the outside of the partition wall 17 and the inner surface of the sky dome D.

By lighting up with blue and red light using the spotlight 11 for presentation, it is possible to produce effect scenes ranging from dark blue sky to sunset.

853 irradiation units U installed on the inner surface of sky dome D
are all configured to emit white light, so they can express the brightness distribution of the sky, but they cannot express the blue sky. Similarly, it is not possible to express sunsets or sunrises, so in order to create such a state, the brightness of the light irradiated by the white irradiation unit L-U is colored with blue and red. It is.

There are 45 performance spotlights 11 arranged, but there are 15 dimming circuits, and each of the 45 spotlights has blue and blue lights.
Covered with red and white filters, they are divided into 3 sets of 15 lights: a blue spotlight, a red spotlight, and a white spotlight, each of which can be turned on. This expresses the blue sky, sunsets and sunrises, and the whiteness of the day.

The atmosphere lighting mechanism will be explained in detail with reference to FIGS. 4, 5, and 6.

45 performance spotlights 11 are arranged along the outermost position of the inner circumference of the sky dome D, and only the sky dome entrance part of the performance spotlights 11 is set as set Y for sunset. It is movable. The sunset is St. Y
In this section, several lighting spotlights 11 are arranged on the moving trolley, and the lighting spotlights 11 are equipped with a red filter to create a red atmosphere on the surface of the white sky irradiation unit U. It is configured to be colored.

In the sunset, the position of set Y is exactly where the artificial sun S sets and the sunset occurs, and the entrance and exit of the sky dome is formed at the position of the sunset sun.

Furthermore, an air conditioning duct K is disposed below the performance spotlight 11 and between the inner periphery of the sky dome D and the partition wall 17. Cooling air is blown into the air conditioning duct from an air conditioning mechanism 20 into the sky dome D.

The cooling air blown into the sky dome D from the air conditioning duct) K cools the inside of the sky dome D, and
The light source of the irradiation unit U is cooled by coming out of the sky dome D through the gap between the 53 irradiation units U.

In addition, in Fig. 1, at the central position within the sky dome D,
A rotating model stand 14 is arranged.

The rotating model table 14 is rotated above the horizon level LL by a rotation control drive mechanism N.

The rotation of the rotating model table 14 creates morning and afternoon because the artificial sun S moves only 90 degrees from the horizon to the center of the sky, and in the morning it rotates from east to due south. At noon, it is due south, and in the afternoon it gradually moves westward. Then, when the state of -day is expressed, the rotating model table 14 is returned to its original position in the morning.

In FIG. 1, a house model H is placed 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. There is.

Also, inside the sky dome D, changes in the brightness of the sky on -day,
Looking at the changes in the artificial sun S, the sun only moves up and down 90 degrees, and the brightness of the sky only changes at the same position, just like the house model 11 on the rotating model stand 14. If you don't move, you won't be able to experience a state close to the state of movement on -day.

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

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

Next, referring to FIG. 10, the operation display section of the artificial sky device of the present invention will be explained.

With the artificial sky device of the present invention, sky lighting experiments, solar radiation/shade experiments, effects production, demonstrations, etc. can be performed.

That is, the sky lighting experiment is performed only by irradiation from the irradiation unit U without raising and lowering the artificial sun S.

It is possible to illuminate the daylight brightness under certain conditions set by the International Commission on Illumination (CIE), such as the CIE standard clear sky, intermediate sky, CIE standard cloudy sky, and average sky. .

By arranging the house model H under the standard sky conditions and measuring the lighting conditions of each part, a sky lighting experiment can be conducted. The measured values from this sky lighting experiment can provide standard model lighting conditions that can be evaluated when designing homes and buildings.

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

In other words, it is possible to simulate what kind of sunlight and shade will be obtained from a window facing a certain direction in a certain place on a certain day in spring, summer, autumn, and winter.

In the case of this solar radiation/shade experiment, the conditions are created by specifying the month, day, and location, and specifying whether it is a continuous movement of the day or a fixed solar radiation/shade condition at a certain time. It is possible.

Along with the movement of the artificial sun S, the brightness of the sky irradiation unit U also changes from time to time through simulation.

Next, in the case of effect production, three of the red, blue, and white filters of the 45 production spotlights 11 are used as described above.
By selecting one of the 15 units in the set and adjusting the light using the 15 dimmer circuits, you can create ever-changing blue skies, sunsets, and sunrises.

In conjunction with the simulation of the solar radiation/sunshade experiment, the performance spotlight 11 can also perform a continuous simulation from the sunrise to the blue sky to the sunset.

In addition, in the effect production, the artificial sun S is likened to the moon,
By setting the moon's altitude, azimuth, and brightness, you can set the brightness of a moonlit night, create a moon scene, or create a scene with all lights on.

The demonstration was not an experiment to collect data, but rather a demonstration of the CI E15i$ clear sky, intermediate sky, artificial sun S for solar radiation/shade experiments, and changes in sky brightness. It can be done.

(F) Effects of the Invention Since the present invention is constructed as described above, it has the following effects.

With the configuration as claimed in claim (1), since the irradiation unit U emits only white light, it is possible to simulate accurate brightness, but there is a problem in that it is not possible to create conditions such as blue skies, sunsets, and sunrises. We were able to resolve this issue.

In other words, when simulating the sunlight and shadow of the day, it is now possible to simultaneously simulate the atmosphere of the sunrise, blue sky, and sunset.

As claimed in claim (2), by setting the entrance of the sky dome D at the position where the sunset is seen in the west when conducting the solar radiation/solar shadow experiment on a single day, a red filter is inserted in that part. By arranging Seso I-Y for possible sunsets, if Set Y is not used for sunsets, it can be replaced with a spotlight If with a white or blue filter, so This made it possible to more accurately simulate things like blue skies and moonlit nights.

As claimed in claim (3), since the air-conditioning duct L- is arranged overlappingly in the direction spotlight 11 of the atmosphere lighting mechanism, the inside of the sky dome D, which becomes hot due to the large number of irradiation units U, can be efficiently illuminated. When the cooling air blown into the sky dome D leaves,
By passing between the irradiation unit (U), the halogen lamp that is the light source is also cooled, so that the temperature of the irradiation unit (U) can be avoided.
