Embodiment Construction

[0055] if based on Figure 1 to Figure 12 One mode of implementation of the present invention will be described as follows. The plant cultivation system 10 of the present embodiment is, for example, a cultivation system used in a closed artificial light utilization type plant factory.

[0056] This plant cultivation system 10 promotes growth by irradiating far-red light to the plant body so that the leaves of the plant body stand up in the vertical direction. A system with an increased amount of cooperation.

[0057] Furthermore, the present invention relates to an illumination device, a cultivation system, and a cultivation method used in a cultivation facility for cultivating plants using artificial light. Cultivation using artificial light means cultivation using artificial light for at least a part of the light used for cultivation, and does not mean cultivation that does not use sunlight at all. The present invention is applicable to cultivation by combining sunlight a...

Abstract

PROBLEM TO BE SOLVED: To provide an illumination device for plant cultivation using artificial light, which can efficiently irradiate leaves at a lower section of the plant even when applying high intensity light.SOLUTION: The illumination device for plant cultivation includes: a main light source which emits monochromatic light or mixed-colored light of which wavelengths are between 400 nm or more and 700 nm or less and photosynthesis photon flux density is at 200 μmol / m / s or greater; and a far-infrared light source which emits far-infrared light. The main light source and the far-infrared light source include semiconductor light-emitting elements.

Description

technical field [0001] The present invention relates to a lighting device for growing plants using artificial light, a plant growing system and a plant growing method. Background technique [0002] With the improvement of agricultural technology, the requirements for plant factories are getting higher. Plant factories are difficult to be affected by weather / climate, etc., so the annual / planned production of plants becomes possible. In particular, the amount of light required for cultivation of leafy vegetables such as lettuce is low, and cultivation in plant factories is progressing. [0003] In plant factories, artificial light from fluorescent lamps is mostly used to cultivate plants. In addition, recently, although it is in the stage of research and development, the cultivation of artificial light using a semiconductor light source is also being studied. In the cultivation based on artificial light, it is known that the amount and quality of light have a great influenc...
