Abstract

PURPOSE:To provide the subject device suitable for efficiently, uniformly and excellently growing plants by arranging illuminators in the upper part of a device main body and disposing a light energy-controlling member between the illuminators and a plant-growing space. CONSTITUTION:The objective device is characterized by disposing illuminators 2 having light sources therein, respectively, in the upper part of a box-like device main body 1 and further by disposing a light energy-controlling member 5 between the illuminators 2 and a plant-growing space 4 so as to control the light energy in response to the kind and growth degree of the plants. The light energy-controlling member 5 is preferably composed of an elastic material comprising the belts of a transparent material and the belts of an opaque material, the belts being alternately arranged, and the light energy-controlling member 5 is preferably expanded or contracted to control the light energy.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to improvements in plant growing equipment.

[0002]

2. Description of the Related Art In recent years, important factors in an apparatus for growing plants are light quantity, temperature, humidity, carbon dioxide concentration and the like.
Among these, in order to change the amount of light, conventionally, for example, a method of adjusting the input to the light source mounted on the plant growing device by a lighting device to change the illuminance, mounting a number of light sources on the plant growing device, and turning on the light source. A method of changing the illuminance of the cultivation room by increasing or decreasing the number, a method of changing the illuminance by adjusting the light-shielding body by providing an adjustable light-shielding body between the plant and the light source attached to the plant growing device are carried out. ing.

[0003]

By the way, according to the above-mentioned plant growing device, the input adjustment range is limited, so that there is a drawback that the change of the illuminance cannot be adjusted in a wide range. Further, according to the plant growing device, the number of light sources is increased, the arrangement of the light sources is complicated, the uniformity of illuminance in the device is impaired, and further continuous illuminance change cannot be obtained. According to the plant growing apparatus of No. 3, since the light shield is manually operated, there is a drawback that continuous illuminance change cannot be obtained.

The present invention has been made in view of the above points, and an object thereof is to provide a plant growing apparatus capable of continuously and automatically changing the illuminance of a cultivation room.

[0005]

The present invention has the following constitution in order to solve the above problems. That is, an illuminator having a light source mounted therein is arranged inside the box-shaped apparatus main body. A light amount adjuster is arranged between the light source and the plant growing space, and the light amount is changed according to the type and growth of the plant. According to a second aspect of the present invention, the light amount adjusting body is made of an elastic material, and the elastic material is made of a transparent material and a non-light transmitting material, and the light amount adjusting body is expanded and contracted to adjust the light amount. There is.

[0006]

According to the plant growing device having the above-mentioned structure, the light amount adjusting body is arranged between the light source and the plant growing space, so that the irradiation light amount for the plant can be automatically and finely adjusted. It can be adjusted according to the growth of plants.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to FIGS. In the figure, 11 is a box-shaped device main body, 12 is an illuminator arranged inside the upper part of the device main body 11, and 13 is a light source mounted inside the illuminator 12, for example, 4
It is configured by mounting three 00 watt high-pressure discharge lamps. Reference numeral 14 is a plant growing space, and 15 is a light amount adjusting body arranged between the irradiator 12 and the plant growing space 14, and is configured to change the light amount according to the type and growth of the plant. The light amount adjusting body 15 is made of an elastic material by alternately connecting a band-shaped transparent material and a non-transparent material. The elastic material is made of, for example, thin rubber. When this elastic material is stretched about 3 times as shown in FIG. 5 from the initial state shown in FIG. 4, the non-translucent portion increases and the illuminance is about 1500.
0 looks will be about 5000 looks. Reference numeral 16 is a motor for pulling the light amount adjusting body 15.

[0008]

As described above, according to the present invention, the light quantity adjusting body, which is made of elastic material and is composed of light-transmitting material and non-light-transmitting material, is alternately arranged between the light source and the plant growing space. Since it is configured, the amount of light can be adjusted by expanding and contracting the light amount adjusting body, and it has a unique effect that the irradiation light amount can be automatically and finely adjusted according to the type of plant and the growth of the plant. .
