Definitions

  • the invention has for its object to provide a fluo ⁇ rescent lamp which has a light intensity over the different constituent components which is optimal for plant growth.
  • this is achieved with a fluorescent lamp particularly for illuminating plant material for culture, wherein in the emitted light spectrum the light intensity ratio between red with a wavelength of 635-685 nm and far red with a wavelength of 705-755 nm amounts to at least 1 and the light intensity ratio between red with a wavelength of 635-685 nm and blue with a wavelength of 400-500 nm amounts to about 1.
  • the proportion of the light intensity of red and blue between respectively 600-700 nm and 400-500 nm in the total light spectrum (400-700 nm) amounts together to 60-70% and the light intensity of blue between 400-500 nm amounts to about 20% of the total light spectrum (400-700 ran) .

Abstract

On utilise l'éclairage artificiel pour la culture des végétaux, par exemple dans des pièces climatisées fermées. De manière à obtenir un résultat optimum, le rapport d'intensité lumineuse entre rouge possédant une longueur d'onde de l'ordre de 635 à 685 nm et rouge lointain possédant une longueur d'onde de l'ordre de 705 à 755 nm, doit être d'au moins 1, et le rapport entre rouge possédant une longueur d'onde comprise entre 635 et 685 nm et bleu possédant une longueur d'onde d'environ 400 à 500 nm doit être d'au moins 1 pour le spectre de lumière utilisé.
