Description

[Detailed description of the invention] [Industrial field of application] The present invention is a system for attaching a plant cultivation pot to a cylindrical body set upright on a base, such as in a vertical tube type hydroponic cultivation device. The present invention relates to a lighting device for a plant cultivation device.

[Conventional technology and its problems]

Utility Model Publication No. 52-828 describes a device for hydroponic cultivation of ornamental plants indoors, in which a cylindrical body is erected on a base with a tank, and a large number of plant cultivation pots are placed in multiple vertical stages on this cylindrical body. They also propose a structure in which the tube is mounted radially in plan view, and the nutrient solution contained in the tank is made to flow down inside the cylinder to be supplied to each plant cultivation pot.

This configuration has the advantage that ornamental plants can be easily cultivated indoors, but since it is installed indoors, there is a lack of sunlight, which slows the growth of the plants, and if the plants are placed at night or in a dark place. had the problem of not being able to emphasize the beauty of the interior.

In order to solve these problems, it would be possible to install a stand type light near the hydroponic cultivation equipment and illuminate the plants with the light from the outside, but with this method, the light Since the light is directly irradiated from only one direction, there is not enough shade to make the plants stand out, and since the stand must be installed separately from the hydroponic cultivation equipment, there are also problems in terms of indoor layout. will occur.

The present invention is designed to make plants more beautiful and illuminate plants without disturbing the harmony of the room in a hydroponic cultivation device using such a vertical tube or a plant cultivation device in which a flower pot is attached to a vertical tube. The purpose is to

[Means for solving problems]

In order to achieve this object, the present invention provides a vertical plant cultivation device in which a plant cultivation pot is attached to a cylindrical body set upright on a base.
A pair of left and right columns extending along the cylindrical body are erected, and an upper illumination device consisting of a downwardly opened upper case made of an opaque plate surrounding the lamp is mounted on the upper portions of the left and right columns. While installing the tube so that the periphery of the cylinder is illuminated from above,
At the rear of the cylindrical body, an indirect lighting type rear illumination device is attached, which is comprised of a lamp covered with an opaque plate cover with a rearward opening, and a reflector mounted between the pillars.

[Functions and effects of the idea]

With this configuration, the plants planted in the plant cultivation pot attached to the cylindrical body are not only illuminated from above by the upper lighting device, but also from behind by the indirect lighting from the rear lighting device. The plants are illuminated so that their silhouettes appear in the space. Furthermore, since the upper lighting device and the rear lighting device are integrated into the plant cultivation device, they do not disturb the indoor layout.

Therefore, according to the present invention, the two lighting devices integrated into the plant cultivation device can illuminate the plants in a way that makes them appear in the space, which helps the growth of the plants and improves the growth of the plants. This has the effect of achieving beautiful lighting without deteriorating the indoor layout.
