Abstract

Titre : Système optique pour module lumineux L’invention concerne un système optique de projection qui comprend :- un groupe optique d’entrée (10) avec une première lentille (11) et une deuxième lentille (12), recevant des rayons lumineux issus d’une source lumineuse (1) et les faisant converger ;- un groupe optique intermédiaire (20) comprenant une lentille (21), le groupe optique intermédiaire (20) recevant des rayons depuis le groupe optique d’entrée (10) pour les faire diverger;- un groupe optique de sortie (30) comprenant au moins une lentille (31), le groupe optique de sortie (30) recevant des rayons lumineux depuis le groupe optique intermédiaire (20) pour les faire converger.
