Abstract

L'invention concerne un module optique (10) pour véhicule automobile comportant : - une source lumineuse (16) ; - un radiateur (22) comportant une plaque (24) présentant une face avant (26) de support de la source lumineuse (16) et comportant une face arrière (28) hérissée d'ailettes (30) de refroidissement ; - un dispositif (42) de production d'un flux d'air ; caractérisé en ce que le radiateur (22) comporte au moins un évent (40) qui traverse la plaque (24) du radiateur à proximité de la source lumineuse (16) pour permettre au flux d'air de circuler longitudinalement entre l'avant et l'arrière du radiateur.
