Description

DETAILED DESCRIPTION OF THE INVENTION a. Field of Industrial Application The present invention relates to an apparatus for growing organisms, particularly an apparatus for cultivating organisms that uses both artificial light and natural light.

b. Prior Art Conventionally, there is a biological cultivation device that artificially creates a biological cultivation environment within a case having an opening/closing door and grows plants and the like within that environment.

Such biological cultivation equipment generally uses artificial lights, coolers, etc. to control the illuminance, ii degree 1. Humidity can be adjusted appropriately.

C1 Problems to be Solved by the Invention However, such biological cultivation equipment uses an artificial light source, such as a fluorescent lamp or a high-pressure sodium lamp, as a light source, and therefore consumes electricity regardless of the daytime skin, making it uneconomical. .

In addition, artificial light sources are unbalanced light rays with bright lines everywhere, and their output is constant and does not change, so they are inferior to natural light for plant growth.

Furthermore, artificial light sources tend to generate heat, and it was necessary to adjust the temperature using a cooler or the like to prevent the inside of the case from heating up to the temperature above a certain plate.

The present invention has been made in view of the problems that the conventional biological cultivation apparatus described above has, and its purpose is to provide a biological cultivation apparatus that can solve the above-mentioned problems by utilizing not only artificial light but also natural light. Our goal is to provide the following.

d. Means for Solving the Problems In order to solve the above-mentioned problems, the gist of the present invention is as follows:
In addition to arranging multiple fluorescent lamps in a case with an opening/closing door, sunlight collected by a condensing lens is guided into the case through an optical fiber cable, and both artificial light and natural light are used as a light source. The feature is in the biological cultivation device.

e. Function As described above, the present invention uses artificial light from a plurality of fluorescent lamps disposed inside the case and light condensed by an outdoor condensing lens as a light source necessary for growing the living organisms housed in the case. Since both sunlight and natural light guided into the case through an optical fiber cable are used together, on sunny days, it is possible to provide light only with natural light, resulting in an energy saving effect.

In addition, the natural light emitted from the end of the optical fiber cable is filtered at the input end face of the optical fiber cable using the chromatic aberration of the condensing lens, and harmful wavelengths are filtered out due to the light transmission characteristics of the optical fiber cable. The sunlight emitted from the output end of the optical fiber cable has ultraviolet rays and heat rays harmful to plant growth removed, and only light components effective for photosynthesis of plants are emitted. Since the sun's light intensity, color, and temperature change from moment to moment in the same rhythmic pattern, these pre-emptive changes have an impact on plant growth and photosynthesis, and have the effect of further promoting their growth. .

Furthermore, unlike artificial light such as fluorescent lights, natural light radiates less heat, making it easier to adjust the temperature using a cooler or the like.
