DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting technique for a building having a dome-shaped roof.

[0002]

2. Description of the Related Art Hitherto, a roof has been configured to be a movable roof which can be freely opened and closed, and the roof is opened to form a lighting opening in the interior to receive light.

[0003]

However, according to the above-mentioned prior art, the roof itself is movable and the daylight is taken. Therefore, the roof is opened and closed, that is, a structure for adjusting the amount of light, particularly the roof is opened and closed. The supporting structure for freely supporting and the driving structure for moving the roof have become very large, which has led to an increase in cost. In addition, since the roof is opened for daylighting, an opening is inevitably formed in the roof at the time of daylighting, and the influence of wind and rain is great. That is, at the time of the wind and rain, the wind and rain enter the inside from the opening as in the case without the roof. SUMMARY OF THE INVENTION An object of the present invention is to make it possible to adjust the amount of light to be collected without being affected by the weather.

[0004]

A feature of a lighting device for a building according to the first invention of the present invention is a building having a dome-shaped roof, wherein the roof mainly comprises a light-transmitting roof material. part was formed, the lighting circuit to the internal building through the lighting part, disposed daylighting adjustment means having a light-shielding ceiling for adjusting the lighting amount by a plurality of light shield, shielding state of the light-shielding ceiling
The state in Aru that provided the height changes and fixed freely operation means being maintained. A feature of the lighting device for a building according to the second invention of the present invention is that, in the first invention, a plurality of light shields having a variable width are included in the lighting adjustment device.
An arrangement is provided in which the light-receiving path is shielded by contacting an adjacent one in the width direction at the maximum width, and operating means for changing and fixing the width of these light-shielding members is provided. In order to constitute the light shielding body, it is preferable to provide a pair of frames whose relative positions can be freely changed in the width direction, and to stretch a flexible light shielding film between the frames. A feature of the lighting device for a building according to the third invention of the present invention is that, in the first invention, the light shielding body is
It is in a ring shape in plan view.

[0005]

According to the first aspect of the present invention, the roof is not opened and closed, but a fixed roof is provided to the last, and a light-receiving portion made of a light-transmitting roof material is formed on the roof to enable light to enter the interior. Since the lighting adjustment means is provided above and the lighting amount is adjusted by the lighting adjustment means, the lighting amount can be adjusted without being affected by the weather, and
The daylighting adjustment means is not required to have a function as a roof, and a light-shielding body and its supporting structure and operating means can be simplified, while having a movable configuration for adjusting the daylighting amount.
Further, since it is be relocated as well as fix the height of the pre-Symbol shielding ceiling by the operation means, e.g., at reduced shielding ceiling to floor level of about buildings, various devices in the ceiling (e.g., a speaker and lighting・ After mounting an exhibit, etc., the various devices can be lifted and the various devices can be set at appropriate heights by a simple operation of simply raising the light-shielding ceiling. Furthermore, the spatial volume product between floors and the light-shielding ceiling in a building interior, by the light shielding ceiling vertical position movement operation, it is possible to easily change, adjust or reverberation time according to the intended use on the floor, It is possible to respond to diversified demands such as changing the sense of visual feeling in the room, creating a sense of unity of the indoor space, and setting a space that emphasizes the live feeling. In particular, the operation
Changing the volume of space by means of
Since it can be carried out while holding it,
Use the space between the floor and the light-shielding ceiling in a light-shielded state
(Use for concerts, movie screenings, lectures, etc.)
In such a case, depending on the respective purpose,
Change the volume to a favorable one, for example to improve the sound effect
To improve the air-conditioning effect,
To give you a sense of pressure
It becomes possible. Conversely, changing the volume of the space
When changing the space, keep the light-shielded state of the space
It can be. According to the second aspect, the widthwise ends of the light shields adjacent in the width direction change in the horizontal direction relative to each other in accordance with the width change of the light shields, whereby the horizontal position of the gap between the adjacent light shields is changed. Since the width in the direction changes, and the gap between the adjacent light shields becomes an optical path that allows transmission of the light into the interior, the horizontal width of the gap between the adjacent light shields is changed by changing the width of the light shield. To adjust the amount of light collected. And since the amount of light is adjusted by changing the width of the light shield, the load of the light shield can be supported at a fixed position in the vertical direction,
The support structure of the light shielding body can be made simple while the support thereof can be made highly reliable. In particular, when the light shield comprises a pair of frames and a light shield film, the light shield can be made lighter, and the strength and rigidity required for the support structure of the light shield can be reduced. According to the third invention, in particular, since the light shield is formed in a ring shape in a plan view, the vertical width of the gap between the light shields can be changed collectively over the entire circumference, so that light is collected from all the circumferences. Adjustment of the amount of light can be performed quickly.

[0006]

According to the present invention, therefore, it is possible to provide an all-weather building that can be implemented at a low cost because the structure for adjusting the amount of collected light is lightweight , and at the same time, the ceiling height can be reduced.
Can be changed to accommodate the diversification of usage . In particular, according to the second aspect, the configuration for adjusting the amount of collected light can be further reduced, so that the cost can be reduced, and according to the third aspect, the configuration for adjusting the amount of collected light can be achieved. The cost can be further reduced by further reducing the weight of the configuration of the first embodiment, and according to the fourth aspect, the adjustment of the amount of light to be taken when light is taken from the entire periphery can be performed with good operability. Can be.
