Abstract

Le problème décrit par la présente invention est de permettre l'éclairage d'une face à exposer qui est verticale par rapport à l'axe optique d'une lentille, depuis la face avant de celle-ci, avec un contour ovale et de manière efficace. La solution de l'invention porte sur une lentille plane-convexe (3), qui reçoit la lumière directe provenant d'une source de lumière à LED (1) ancrée au centre de la face avant d'un radiateur à chaleur (2), dans la longueur focale côté réception de lumière de celui-ci, et l'axe optique de la lentille servant de centre de la réception de lumière, est disposée de manière coaxiale et parallèle à un tube intérieur (4) qui recouvre le radiateur à chaleur (2). Une lentille de Fresnel plane-convexe (5) et une lentille de Fresnel linéaire (6), qui se situent près de la lentille plane-convexe (3) et dans la longueur focale côté sortie de lumière de celle-ci, et convertissent un flux lumineux ayant le contour d'un cercle parfait en un flux lumineux au contour ovale, sont disposés à proximité l'une de l'autre, et de manière coaxiale et parallèle à un tube extérieur (7) qui recouvre le tube intérieur (4). Le flux lumineux ayant le contour d'un cercle parfait est de ce fait converti en flux lumineux au contour ovale, l'axe mineur de celui-ci étant plus court que le diamètre du flux lumineux ayant le contour d'un contour cercle parfait et l'axe majeur de celui-ci étant plus long que le diamètre du flux lumineux ayant le contour d'un contour cercle parfait, et l'éclairage d'une face à exposer (B) qui est verticale par rapport à l'axe optique de la lentille avec un contour ovale est possible, à l'aide de ce flux lumineux au contour ovale.
