Abstract

L'invention concerne un système, qui est mis au point pour transférer la lumière vers les régions qu'elle ne peut pas atteindre dans les unités de culture d'algues et/ou de micro-algues de type ouvertes et/ou fermées; est constitué d'héliostats qui réfléchissent la lumière du soleil vers le miroir concave, de lentilles de Fresnel qui permettent d'obtenir que la lumière passe du miroir concave à des fibres optiques de manière focalisée sans perte et, de fils et/ou de plaques à fibre optique qui passent à travers le milieu de la colonne d'un photobioréacteur à colonne ou d'un bassin photobioréacteur fermé. La lumière est réfléchie à partir des héliostats et est dirigée sur le miroir concave et la lumière provenant du miroir concave est transportée vers les fils à fibre optique par l'intermédiaire des lentilles de Fresnel dans le système de l'invention. Un milieu de croissance de micro-algues de type bassin ouvert et/ou fermé qui a une profondeur supérieure à 30 cm peut être éclairé de façon homogène grâce au système. En outre, il est prévu que le coût énergétique soit diminué par l'éclairage depuis l'intérieur avec la lumière du soleil sans nécessité de lumière fluorescente dans la journée dans le photobioréacteur de type fermé.
