Abstract

L'invention concerne un module d'éclairage ou de signalisation pour l'émission d'un faisceau d'éclairage ou de signalisation selon une direction principale, du type comprenant une source lumineuse (11), un miroir récupérateur de flux lumineux comportant un ensemble de pavés réflecteurs (20i), la surface réfléchissante de chaque pavé réflecteur (20i) étant constitué d'une portion de première conique à deux foyers dont un premier foyer est situé sur la source lumineuse (11) et dont un second foyer (Fi) est situé par rapport au pavé réflecteur (20i) dans une direction spécifique par rapport à la direction principale, chaque pavé réflecteur (20i) formant une image (Fi) de la source lumineuse (11). Selon l'invention, la surface d'au moins un pavé réflecteur (20i) comporte au moins une fraction de deuxième conique à deux foyers (20i,j) dont un premier foyer est situé sur la source lumineuse (11) et dont un second foyer (Fi,j) est situé à distance du second foyer (Fi) de la première conique à deux foyers. Application aux véhicules automobiles.
