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. Figure pour l’abrégé : Fig. 1Title: Optical system for light module The invention relates to a projection optical system which comprises:- an input optical group (10) with a first lens (11) and a second lens (12), receiving light rays from a light source (1) and making them converge;- an intermediate optical group (20) comprising a lens (21), the intermediate optical group (20) receiving rays from the input optical group (10) to make them diverge;- an output optical group (30) comprising at least one lens (31), the output optical group (30) receiving light rays from the intermediate optical group (20) to make them converge.
