Abstract

L’invention concerne un module lumineux (100) de projection en champ proche, comprenant : - une source de lumière (110) apte à émettre un faisceau lumineux ; - un premier miroir mobile (120) apte à commuter entre plusieurs positions de manière à faire varier une direction d’un faisceau réfléchi (181) issu de la source de lumière; - un ensemble (130) de masques (132.1-132.5) associés à des motifs (131), et agencés de manière à être sélectivement éclairés par le faisceau réfléchi, en fonction de la position du premier miroir mobile ; - un miroir de repliement (140) apte à replier un faisceau lumineux (182) ayant traversé l’un des masques vers un système optique de projection (150) du module lumineux. Le système optique est apte à projeter en champ proche le faisceau lumineux replié de manière à former le motif correspondant au masque sélectivement éclairé. FIG. 1
