Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light environment device for plants placed indoors.

[0002]

2. Description of the Related Art Recently, it has become popular to plant trees in an atrium or the like inside a building or the like. These trees are irradiated with natural light such as sunlight through the glass of the ceiling, supplemented with artificial light in addition to natural light, or irradiated with only artificial light.

[0003]

However, the amount and direction of natural light such as sunlight introduced into a building is limited, and a small tree can be used to move a pot, but a large tree. Then you can't do that either. In addition, if you try to irradiate or supplement light with artificial light to the entire tree sufficiently, you must arrange a considerable number of lamps in the surrounding area, and lighting equipment and electricity costs are heavy, so partial irradiation is presently done. Is limited to. In addition, there are cases where there is no place to place a large number of lighting fixtures, the lighting fixtures are not visible because they are invisible to the human eye, and the light from the lighting fixtures cannot enter the human eyes directly.

Therefore, the required amount of light is not spread over the entire tree, and the tree shape is destroyed. Therefore, a tree planter replaces the trees planted in pots every few months and regenerates them in warm regions, but it takes 3 to 5 years to regenerate them. Moreover, in buildings and the like, larger trees are being arranged, and when the trees become larger, it is not easy to carry them out or introduce them for replacement, and it is expensive.

An object of the present invention is to provide a device which can grow plants placed indoors in a good light environment for a long period of time without exchanging them.

[0006]

According to a first aspect of the present invention, there is provided a light environment device for indoor arrangement of plants, wherein a tree is rotatably arranged inside a building, and an illumination device for irradiating the tree is shaded in a visible range. It was placed at a location and the whole tree was illuminated by a lighting device while rotating the tree.

In the indoor environment light environment device for plants according to claim 2, a tree is rotatably arranged at a location inside a building where natural light enters directly or through glass or the like, while lighting for illuminating the tree inside the building. A device is installed, and a control device that controls the lighting device by measuring the amount of natural light that enters the building from the outside and irradiates the tree is installed.While rotating the tree, the lighting device provides an insufficient amount of natural light to the entire tree. The light is supplemented according to the above.

[0008]

According to the first aspect of the invention, the tree rotates while uniformly receiving the light from the luminaire arranged in the shadow of the visible range in the building.

According to the second aspect of the present invention, the amount of natural light such as sunlight entering the room is measured. When the amount of natural light falls below a predetermined lower limit value, the lighting device is activated, and when the amount of light exceeds a predetermined upper limit value, the lighting device is turned on. Deactivated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an example in which the indoor environment light environment device for plants according to the present invention is arranged indoors where no natural light such as sunlight enters. The device is a rotating device arranged on a floor 3. 1
And a lighting device 2 arranged on the ceiling 4.
The tree 6 planted in the pot 5 is arranged on the rotating device 1.

As shown in FIGS. 2 and 3, the rotating device 1 includes a main body 1
0 and a rotary table 11, the rotary table 11 is rotatably supported by a rotary shaft 12 in the main body 10, and is rotated by a motor 13 via gears 14 and 15. Reference numeral 16 is a bearing, and 17 is a shaft support member. In addition, a timer (not shown) for controlling the operation stop of the motor 13 is arranged in the main body 10.

The illuminating device 2 is composed of a plurality of luminaires 7 arranged in one place, and a lamp 8 is arranged in each of them. This illuminating device 2 is arranged at a place behind the visible range. That is, in this embodiment, it is embedded in the ceiling so as not to enter the viewing angle.

For example, in the case of a tree with a height of 5 m, the lighting device 2
Six lamps of 400 W are used for this, and the tree 6 is irradiated from a position 3 m away, and the illuminance on the tree-shaped surface of the tree is set to 10,000 lux. The irradiation angle of each lamp is different, and 6 lights cover the entire tree.

The rotary table 11 may be rotated, for example, 90 ° and then stopped for 20 minutes or more and then rotated again by 90 °, or may be rotated continuously and slowly. Irradiating a tree with 10,000 lux is quite bright,
The illuminance may be reduced during the daytime so that the illuminance is high only at midnight when there are no people. Even if the lighting device has a fixed angle,
Alternatively, the irradiation may be variable or the irradiation may be performed while automatically changing the angle.

The rotating device 1 may be embedded in the floor 3 as shown in FIG. This makes it easy to dispose the bowl 5 on the turntable 11. The location of the lighting fixtures 2 is not limited to one, but it is easier to place the lighting fixtures 2 in a place that is less visible to the eyes, and it is easier to place the lighting fixtures 2 in construction, maintenance and inspection, and measuring the light intensity of the lighting fixtures. Etc. are easy.

FIG. 5 shows a state in which the device of the present invention is placed indoors having a glass portion 20 that transmits natural light such as sunlight. In addition to the rotating device 1 and the illuminating device 2, the amount of natural light is measured. The control device 21 controls the lighting device. The lighting device 2 is composed of a plurality of lighting fixtures 7 arranged in one place, and 7a is a ballast. An illumination sensor 22 is connected to the control device 21, and the illumination sensor 2
2, the illuminance of natural light transmitted through the glass portion 20 is measured, and when the illuminance of the natural light falls below a predetermined lower limit value (for example, 10,000 lux), the rotating device 1 and the illuminating device 2 are operated, and a predetermined upper limit value (for example, 20,000 lux) or more. Then, the rotating device 1 and the lighting device 2 are deactivated. Note that a delay timer of about 10 minutes may be provided so that the rotating device 1 and the lighting device 2 do not operate each time the sunlight is temporarily blocked by a cloud or the like.

It should be noted that when the natural light is sufficiently indoors, the lighting device 2 does not operate and only the rotating device 1 rotates to apply the natural light to the entire tree, and when the natural light becomes insufficient or at night, the rotating device is used. 1 may operate in conjunction with the lighting device 2.

Also in this case, the illuminating device 2 may be arranged at a place behind the visible range or collectively at a plurality of places.

The device of the present invention is not limited to a large tree,
It can be used for small plants and in greenhouses.

[0020]

In the indoor environment light environment device for plants according to claim 1, since the lighting device evenly irradiates the rotating tree with light, the tree receives a sufficient amount of light necessary for photosynthesis. , It is possible to grow for a long time without losing the tree shape of the tree.

Further, since the tree rotates, the whole tree can be efficiently irradiated with a small number of lighting fixtures, the equipment cost and running cost of the lighting fixtures are low, and maintenance and inspection and the light quantity measurement of the lighting fixtures are easy. Is.

Further, by arranging the luminaire in a shaded part of the visible range, it is possible to irradiate the light in a state where strong light does not enter the eyes of the person, and the aesthetics of the building is not spoiled.

In the indoor environment light environment device for plants according to claim 2, in the growth of trees in a building using natural light such as sunlight, it is always good without being affected by changes in weather and seasonal light quantities. It can be grown in a bright light environment and can maintain its tree shape for a long time.
