Abstract

La présente invention concerne un dispositif (10) d'éclairage et/ou de signalisation, notamment pour véhicule automobile, comprenant une source de lumière (12), une surface de transmission (11) et des moyens de distribution d'au moins une partie de la lumière issue de la source (12) sur la surface de transmission (11), les moyens de distribution comprenant une matrice (14) de micro-miroirs pilotable suivant au moins deux configurations différentes de distribution. La source (12) à sa sortie est quasi ponctuelle.The present invention relates to a device (10) for lighting and / or signaling, in particular for a motor vehicle, comprising a light source (12), a transmission surface (11) and distribution means of at least a part light from the source (12) on the transmission surface (11), the distribution means comprising a matrix (14) of micro-mirrors controllable in at least two different distribution configurations. The source (12) at its output is almost punctual.
