Title
(EN) ILLUMINATOR FOR PLANT GROWTH
(FR) ILLUMINATEUR POUR LA CROISSANCE DES PLANTES
Abstract
(EN)
An illuminator for plant growth by illuminating a plant intermittently (pulse illumination) or continuously and thereby producing an effect similar to sunbeam spot phenomenon so as to accelerate photosynthesis. The illuminator has a light source composed of a semiconductor optical device, demodulates the light from the light source with a rhythm signal generated artificially or extracted from sound present in the natural world, and illuminates a plant to be illuminated with the modulated light. Specifically the illuminator comprises a light source composed of a semiconductor optical device, a control unit for outputting a turn-on timing signal for the light source, a rhythm signal detecting unit for A/D converting an inputted rhythm signal, a timing signal modulating unit for modulating the turn-on timing signal with the output signal from the rhythm signal detecting unit, and a pulse drive unit for pulse-modulating a power signal with the modulated turn-on timing signal and supplying the power signal to the light source.

La présente invention concerne un illuminateur pour la croissance des plantes par l'éclairage intermittente (éclairage par impulsions) ou continue produisant ainsi un effet semblable au phénomène de rayon de soleil localisé afin d'accélérer la photosynthèse. L'illuminateur présente une source lumineuse constituée d'un dispositif semi-conducteur, effectue une démodulation de la lumière provenant de la source lumineuse avec un signal de cadence généré artificiellement ou extrait d'un son existant dans le monde naturel, et éclaire la plante grâce à ladite lumière modulée. Notamment, l'illuminateur comporte une source lumineuse constituée d'un dispositif semi-conducteur optique, une unité de commande produisant un signal de temporisation pour la mise en marche de la source lumineuse, une unité de détection de signal de cadence permettant une conversion analogique numérique du signal de cadence produit, une unité de modulation de signal de temporisation permettant de moduler le signal de temporisation de mise en marche avec le signal de sortie en provenance de l'unité de détection de signal de cadence, et une unité de génération d'impulsions permettant de moduler en impulsions un signal de puissance avec le signal de temporisation modulé de mise en marche et de fournir le signal de puissance à la source lumineuse.
