Abstract

La présente invention concerne un dispositif lumineux (1) comprenant une source lumineuse à DEL (3) et des éléments optiques positionnés dans l’axe optique de ladite source lumineuse (3) pour créer un faisceau lumineux, lesdits éléments optiques comprenant un ensemble de microlentilles (6) permettant d’homogénéiser ledit faisceau, caractérisé en ce que l’ensemble de microlentilles (6) est mobile entre une première position active dans ledit axe optique, pour modifier l’homogénéité du faisceau, et une deuxième position inactive.
