Abstract

L'invention a trait à un module d'éclairage (2) notamment pour véhicule automobile, comprenant une première surface réfléchissante (10) de profil elliptique, au moins une source lumineuse (12) située à un premier foyer de la première surface réfléchissante (10), une deuxième surface réfléchissante, dite plieuse (14), avec un bord de coupure situé à un deuxième foyer de la première surface réfléchissante (10), une lentille (8) apte à dévier les rayons provenant des première et deuxième surfaces réfléchissantes (10, 14) afin de former un faisceau d'éclairage selon un axe optique du module, et un dissipateur thermique (6) apte à dissiper la chaleur produite par ladite ou lesdites sources (12) et supportant la plieuse (14). Le dissipateur (6) comprend au moins un bossage (66) dirigé vers le haut et en contact avec la plieuse (14).
