Definitions
- the invention relates to the field of application of LED lamps in agriculture, in particular to an intelligent control device and method for plant growth illumination with LEDs.
- Greenhouse cultivation provides an excellent environment for growing vegetables and provides a new way to increase production.
- the application of LED lamps to plant lighting compensation provides a fine and healthy light environment for vegetables, free from complex outdoor environmental factors, and systematically meets the growth needs of plants, and achieves maximum plant growth requirements with minimum energy consumption. It provides a new possibility for the improvement of vegetable quality.
- the raw materials for visible light cooperation are carbon dioxide and water, the condition is light, the place is chloroplast, the product is organic starch and oxygen, and the factors affecting photosynthesis are light intensity, temperature, humidity, carbon dioxide concentration, etc., so it is not possible to focus on one aspect. Growth factors.
- the peaks of chlorophyll a and b absorption spectra in plants were 660 nm and 450 nm, respectively.
- the LED is monochromatic light, which can meet the monochromatic light spectrum required for plant growth, and can fully agree with the peak of chlorophyll absorption spectrum, which can greatly improve the plant physiological effect of the light source, promote the efficient growth of plants, and improve the utilization of light energy by plants. Efficiency and reduce energy consumption.
- PWM dimming technology is considered to be the most suitable dimming technology for LEDs.
- the switching control signal of the LED driving chip is modulated by controlling the pulse width duty ratio.
- the fast switching characteristics of the LED make PWM dimming possible.
- the dimming method has the advantages of simple application, high precision, high efficiency, and good dimming effect.

Abstract
L'invention concerne un dispositif et un procédé de commande intelligents permettant de réaliser un éclairage pour la croissance des plantes à l'aide de DEL. Le dispositif comprend une unité de traitement de signal (1), un module de source de lumière à DEL (2), une unité de surveillance de facteur d'environnement (3), et une unité de commande de facteur d'environnement (4). Le module de source de lumière à DEL (2) comprend un module de lumière rouge à DEL (2-1), un module de lumière bleue à DEL (2-2), un module de lumière verte à DEL (2-3), un module d'infrarouge à DEL (2-4), et un module d'ultraviolet à DEL (2-5). En combinaison avec la technologie MID, les rapports de lumières rouge, bleue et verte sont commandés pour empêcher un gaspillage de spectre partiel, et une efficacité de supplément de lumière élevée est obtenue. La lumière verte, la lumière ultraviolette et la lumière infrarouge sont ajoutées sur la base de la lumière rouge et bleue requise par la photosynthèse des plantes. La lumière verte facilite la croissance des plantes, en particulier en termes d'aspect de la coloration des feuilles des plantes. La lumière infrarouge peut régler la température de l'environnement ambiant des plantes. La lumière ultraviolette a des effets de stérilisation et de désinfection. Trois facteurs importants, à savoir le dioxyde de carbone, l'eau et la température, sont complétés tandis que la lumière requise est fournie, et les conditions de croissance requises par les plantes sont assurées de manière globale et multidimensionnelle.
