Abstract

L’invention concerne un module optique apte à émettre un faisceau lumineux à débattement digital. Un module optique (22) selon l’invention comprend un réflecteur optique (4) à base ellipsoïdale, une lentille de projection (6), le foyer principal objet (FA) du réflecteur optique (4) et le foyer principal objet de la lentille de projection (6) définissant un axe optique (12), une source de lumière positionnée entre le réflecteur optique (4) et la lentille de projection (6). La source de lumière comprend au moins deux unités lumineuses (28A, 28B) distinctes et alignées sur l’axe optique (12), chaque unité lumineuse est pilotée indépendamment l’une de l’autre par une unité de contrôle (34), et une première unité lumineuse (28A) est positionnée à une distance égale ou inférieure à 1 mm du foyer principal objet (FB) du réflecteur optique (4). (Figure 3)
