Abstract

L'invention a trait à un module d'éclairage comprenant une source lumineuse du type diode à électroluminescence (10, 16) éclairant essentiellement dans un demi-espace , un premier réflecteur (6, 14) et un second réflecteur (8, 12) de plus petite distance focale et disposé entre la source lumineuse (10, 16) et le premier réflecteur (6, 14). La géométrie et la position du second réflecteur (8, 12) sont choisis pour que ce dernier, bien que disposé plus près de la source lumineuse, laisse passer une majeure partie des rayons lumineux émis par la source vers le premier réflecteur générant le faisceau d'éclairage principal. Le second réflecteur (8, 12) collecte une partie des rayons émis par la source qui ne sont pas collecté par le premier réflecteur (6, 14) et génère un faisceau secondaire qui vient s'ajouter au faisceau principal. Cette construction permet de concevoir un module avec un réflecteur principal de taille réduite tout en ayant un rendement énergétique élevé. L'invention a trait également à un projecteur comprenant un premier module et un second module selon l'invention.The invention relates to a lighting module comprising a light source of the light-emitting diode type (10, 16) which essentially illuminates in a half-space, a first reflector (6, 14) and a second reflector (8, 12). of smaller focal length and disposed between the light source (10, 16) and the first reflector (6, 14). The geometry and the position of the second reflector (8, 12) are chosen so that the latter, although placed closer to the light source, lets pass a major part of the light rays emitted by the source towards the first reflector generating the beam d main lighting. The second reflector (8, 12) collects part of the rays emitted by the source which are not collected by the first reflector (6, 14) and generates a secondary beam which is added to the main beam. This construction makes it possible to design a module with a main reflector of reduced size while having a high energy efficiency. The invention also relates to a projector comprising a first module and a second module according to the invention.
