2. Description of the Related Art Conventionally, an artificial sky apparatus itself has been known. According to the artificial sky illumination method, a reflection dome type, a transmission dome type, a direct irradiation dome type, a mirror box type, and the like are known. However, the reflection dome type has good reproducibility in CIE standard cloudy sky and clear sky, but dimming of brightness is difficult. The transmission dome type and mirror box type have good reproducibility in CIE standard cloudy sky, but clear sky. Is poor, and it is difficult to adjust the luminance. In addition, there has been a direct irradiation type artificial sky device from the past, but there was a problem that the whole sky could not be seen as a continuous sky because many irradiation units arranged in the sky were individually separated. It is. In addition, the position of the light source lamp has the highest luminance, and among the irradiation units, the bright and dark areas are clear, making it difficult to understand the sky as a surface.

[0003]

SUMMARY OF THE INVENTION According to the present invention, an artificial sky is constructed by arranging a large number of irradiation units on the inner surface of a sky dome, and the light source lamp portion becomes particularly bright for each unit irradiation unit. In order to avoid this problem, a milky white plate is attached to the front of the reflector so that the square milky white plate at the end has the same brightness as much as possible. In addition, since the surface is constructed by arranging a number of unit irradiation units, a dark part that is not irradiated from either side is created at the boundary part of each irradiation unit, and this dark part becomes a line and a separation line in the artificial sky Although the present invention is possible, the present invention uses a square milky white plate disposed at the tip of the irradiation unit as a bent plate having a cross-section “U” shape, so that the boundary portion also has a square milky white color. Light transmitted through the plate arrives and dark lines are erased.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The problems to be solved and means to be solved by the present invention are as described above. Next, the configuration of the embodiment shown in the attached drawings will be described. FIG. 1 is a cross-sectional side view of a center line 0-0 of the sky luminance distribution simulation apparatus of the present invention, and FIG.
FIG. 3 is a bottom view showing the arrangement of
FIG. 4 is a plan sectional view of the irradiation unit U of the present invention, FIG. 5 is a side sectional view of the same, and FIG. 6 is a front view.

In FIG. 1, an artificial sky device according to the present invention comprises:
The illumination unit U and the artificial sun S are arranged indoors in the sky dome D. Outside the sky dome D, a control computer, an electrical equipment control panel, an indoor expansion monitor TV, a lighting console, an artificial sun console, and the like are arranged, and the brightness of the irradiation unit U inside the sky dome D and the artificial sun The position of S can be simulated by remote control. By the control computer, the sky dome D
, And controls 853 irradiation units U arranged on the inner surface. Since the irradiation units U are configured symmetrically, only 427 sets are controlled by the control computer, and one set is controlled so that the two left and right irradiation units U emit the same luminance. Since the irradiation unit U just above the sky cannot be symmetrical,
One control group is provided, and is configured to adjust the luminance of one irradiation unit U. Therefore, the adjustment circuit by the control computer is 427 circuits, and the irradiation unit U is 85
There are three.

A center line 0-0 shown in FIG. 2 indicates a center position of the sky dome D. On the center line 0-0,
An artificial sun S rising to the position of the true sky is provided. Also, 426 irradiation units U are arranged symmetrically about the center line 0-0 in the east-west direction. 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. Also, at the lower position in the sky dome D,
Forty 45 effect spotlights 11 are arranged at a position inside the circumference of the sky dome D. The production spotlight 11 has 15 control circuits for dimming, and the production control spotlight 11 divides the production spotlight 11 into three sets of red, blue, and white, and controls the brightness of each set. Is adjusted.

FIG. 1 is a sectional view taken along a center line 0-0 provided at the east-west branch point of the sky dome D. The hemispherical sky dome D is a portion above the horizon level LL, and the portion below the horizon level LL is a portion below the horizon that does not form the sky portion. A partition wall 17 is provided circumferentially below the horizon, and
Forty-five stage effect spotlights 11 are arranged outside the space 7 and inside the sky dome D. The effect spotlight 11 illuminates with blue / red light to produce an effect scene from a sunrise to a blue sky and a sunset.

Since the 853 irradiation units U provided on the inner surface of the sky dome D are all configured to emit white light, the brightness distribution of the sky can be expressed, but the blue sky cannot be expressed. is there. Similarly, since a sunset cannot be expressed as a sunrise, 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. . There are 45 spotlights 11 for production,
There are 15 dimming circuits, and 45 units are covered with blue, red and white filters, respectively, and each of the 15 units has a blue effect spotlight, a red effect spotlight, a white effect spotlight, and It is divided into three sets, and by lighting one of the sets, the blue sky, sunset / sunrise, and white in the daytime are expressed. Further, the rotating 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. The rotation of the rotary model table 14
Since the artificial sun S moves only 90 degrees from the horizon to the center of the sky, it creates a morning and an afternoon. Gradually moves to the west. 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. 1, a house model H is arranged on a rotary model table 14, and a lift table 15 and a lift scissors mechanism 16 are configured so that the house model H can be easily adjusted and placed. Have been. In addition, in the sky dome D, when the change in the brightness of the sky and the change of the artificial sun S in the day are observed, the sun only moves up and down 90 degrees, and the brightness changes in the same position in the sky. However, if the user does not move in the same manner as the house model H on the rotary model stand 14, the user cannot 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 house model H so that the viewer can experience this state. The experience chair 1
2 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 rotary model table 14, so that the sun rises from the east and sinks to the west.

4 to 6, a specific configuration of the irradiation unit U will be described. The irradiation unit U is fastened to the arc-shaped dome frame 20 constituting the sky dome D by the fastening bolt 27 via the bracket 21 and the fastening plate 28.
Is fixed. Since the dome frame 20 is a pipe material, a triangular groove 21a is formed on the bracket 21 side so that the dome frame 20 can be held tightly against the pipe material, and is sandwiched with an elastic plate 29 interposed therebetween. A rectangular box-shaped lamp case 25 is attached to the tip of the bracket 21. Inside the lamp case 25, a light source lamp 31 constituted by a mini halogen lamp is provided at the center. The light source lamp 31 uses a mini-halogen lamp, which is a small light source, because halation occurs in a large lamp and uniform brightness cannot be obtained on the entire surface of the square milky white plate 22.

The reflecting plate 30 is also covered with a milky white plate 32 so that the irradiation light from the mini-halogen lamp has a uniform brightness on the surface of the square milky white plate 22, and the light source of the mini-halogen lamp is diffused. It is doing. Even with the diffuse transmission of the reflection plate 30 and the milky white plate 32 alone, a uniform irradiation state on the front surface of the irradiation unit U has not yet been obtained, so the square milky white plate 22 is further disposed on the front surface of the lamp case 25. It is. The milky white plate 32
The light from the mini-halogen lamp diffusely transmits through the portion reflected by the reflection plate 30. Since the mini-halogen lamp is longer than the milky white plate 32, it is not reflected by the reflection plate 30 and is not reflected by the milky white plate. Since the direct light that does not pass through 32 comes out to the front of the lamp case 25, this irradiation light is transmitted irregularly by the square milky white plate 22, thereby obtaining uniform irradiation light.

The square milky white plate 22 is a bent plate having a U-shaped cross section, so that light can be transmitted from the side surface of the square milky white plate 22. The light transmitted from the side surface illuminates a dark part of the gap between the adjacent irradiation units U, thereby preventing the boundary line from being formed. From the square milky white plate 22, a sliding fixing spring 23 protrudes inside the lamp case 25, and a locking metal fitting 24 inside the lamp case 25.
24 and is fixed between them.

As described above, the light from the light source lamp 31 is diffused and radiated when passing through the milky white plate 32 and the square milky white plate 22, and this irradiation unit U serves as one sky element inside the sky dome D. By arranging them neatly, the light concentrated on one point disappears and the sky can be reproduced by irradiating in a nearly natural way.

[0015]

As described above, the present invention has the following advantages. That is, it is possible to constitute a new type of irradiation device intermediate between a conventional transmission dome type which irradiates from the outside of a dome integrally formed with a transmission material and a direct irradiation type in which a lighting device exposed to the entire dome is arranged. As a result, it is possible to provide an irradiation device having both advantages of the continuity as a diffusion light source, which is an advantage of the transmission dome type, and the easiness of brightness control, which is an advantage of the direct irradiation type, and more naturally. It was possible to obtain close lighting.
