Description

  The present invention relates to an artificial lighting device for growing plants and an irradiation method thereof, and more specifically, an artificial lighting device including at least an R66 lamp, a BEX lamp, a WW lamp, and a Ne lamp, The present invention relates to a method for controlling early growth and growth of plants by irradiating artificial light in a light wavelength range required by plants such as Chinese medicine and flowers with a light intensity stronger than other light wavelengths.

  In recent years, in order to provide a stable supply of vegetables and flowers regardless of the season and temperature, artificial fertilizers, water, and light have been cultivated and technology has been developed. Plants suck up water from the roots and carbon dioxide in the atmosphere. If there is, the pigment (chlorophyll) present in the chloroplast in the leaf absorbs light, acquires energy, takes in carbon dioxide gas, stores this as sugar, grows, So-called photosynthesis is performed, in which oxygen gas is released as a by-product.

  Plant growth is performed by light, carbon dioxide concentration, and environmental temperature. If there is water to be sucked up from the roots, depending on the wavelength of the irradiated light, the intensity of the light, the concentration of carbon dioxide gas, and the environmental temperature The growth rate changes greatly.

  In addition, as shown in FIG. 3, the light absorption of plants is mostly due to two types of pigments, chlorophyll a and chlorophyll b. Chlorophyll a absorbs light at 430 nm and 660 nm, and chlorophyll b absorbs light at 460 nm and 650 nm. Is remarkable.

For example, it is a fluorescent glass that exhibits red fluorescence when excited by ultraviolet light using Eu ³⁺ as a fluorescent medium, and the anion of the fluorescent glass is made of F-, and is disclosed for all cations in the glass. An AC voltage obtained by connecting Eu ³⁺ to 5 to 20 mol% (see Patent Document 1) and a magnetic energy regenerative switch composed of four reverse conducting semiconductor switches and an energy storage capacitor in series with a reactor and an AC power supply The resonance of the power supply frequency is caused by turning on / off the switch synchronized with the power supply frequency. If this resonant voltage is taken out by a diode rectifier circuit, a DC voltage higher than the AC input voltage can be obtained, and the input current has less harmonics and a better power factor (see Patent Document 2), or the theoretical “magnetic prototyping” A device for cultivating crops such as strawberry 3 that is cultivated by means of biological life activation based on the principle of “Nix”, applying a very low frequency micro alternating magnetic field to water inside and outside the organism based on the principle of magnetic protonics, Achieving long-distance movement of plants, improving the ability to produce adenosine triphosphate, a cellular energy substance of living organisms, and activating and promoting the growth of useful organisms and useful bacteria in and outside the organism (Patent Literature) 3) and the like.
