HORTICULTURE LIGHTING DEVICE AND METHOD FOR STIMULATING PLANT GROWTH AND BIO-RHYTHM OF PLANTS Russian patent published in 2018 - IPC A01G7/04 

FIELD: agriculture; lighting equipment.

SUBSTANCE: invention relates to a horticulture lighting device, to a method for stimulating plant growth and plant biorhythm, to a lamp comprising said horticulture lighting device, and to a horticulture assembly comprising said horticulture lighting device or said lamp. Said lighting device comprises a solid-state light source configured to emit direct red light having a wavelength of 600–680 nm, preferably 640–680 nm, and a wavelength conversion element configured to receive at least a portion of said direct red light emitted from said solid-state light source, and converting said received direct red light into far red light having a maximum emission wavelength of 700–760 nm, preferably 720–760 nm. Such method for stimulating plant growth and biorhythm of plants comprises the steps, on which direct red light having a maximum emission wavelength of 600–680 nm, preferably 640–680 nm, is formed using a solid-state light source, at least a portion of said direct red light is received in the wavelength conversion element and said received direct red light is converted into far red light having a maximum emission wavelength of 700–760 nm, preferably 720–760 nm, using said wavelength conversion element. Above lamp comprises at least one of said horticulture lighting devices. Above horticulture assembly comprises at least one of said horticulture lighting devices or one of said lamps.

EFFECT: such implementation will increase the efficiency of lighting devices and the effectiveness of lighting plants to stimulate their growth and biorhythm.
