Abstract

L'invention concerne un appareil d'éclairage destiné à faciliter la croissance des plantes. L'appareil d'éclairage comprend une pluralité de sources de lumière émettant de la lumière dans un ou plusieurs canaux de lumière. Chaque canal de lumière peut être utilisé pour éclairer au moins une partie d'une plante à l'intérieur de celui-ci. Un corps forme un passage central à travers celui-ci. Le passage central est sensiblement aligné sur un vecteur de gravité et la pluralité de sources de lumière s'étendent depuis le passage central et sont empilées verticalement les unes au-dessus des autres. Une source d'alimentation est accouplée à la pluralité de sources de lumière et est conçue pour alimenter la pluralité de sources de lumière.
