Abstract

L'invention a trait à un dispositif lumineux (2) d'affichage et/ou de signalisation, comprenant une source lumineuse (4) apte à émettre des rayons lumineux ; un microsystème électromécanique (8) avec une matrice de micro-miroirs pivotants aptes à réfléchir les rayons de la source lumineuse (4) ; et un premier système optique (6) configuré pour collecter les rayons lumineux de la source lumineuse (4) et les faire converger vers le microsystème (8) ; un deuxième système optique (14) configuré pour collecter les rayons lumineux réfléchis par le microsystème (8) et former une image agrandie (20) de l'image du microsystème. Le premier système optique (6) est configuré pour que les rayons réfléchis par les micro-miroirs en position « ON » du microsystème (8) convergent avant d'atteindre le deuxième système optique (14).
