Abstract

Titre : Module lumineux à sources à partie émissive maximisée L’invention concerne un module lumineux pour véhicule automobile, comprenant au moins une première rangée (10) de sources lumineuses configurée pour produire un premier faisceau de sortie (1), et une deuxième rangée (20) de sources lumineuses configurée pour produire un deuxième faisceau de sortie (2), caractérisé en ce que les sources lumineuses de la première rangée (10) et de la deuxième rangée (20) sont des diodes électroluminescentes à partie émissive maximisée, et en ce qu’il comprend un élément optique primaire (30) configuré pour recevoir les rayons lumineux des sources de la première rangée (10) et de la deuxième rangée (20), l’élément optique primaire (30) étant configuré pour produire une réflexion interne des rayons lumineux des sources d’au moins l’une parmi la première rangée (10) et la deuxième rangée (20). Figure pour l’abrégé : Fig.2Title: Light module with sources with maximized emissive part The invention relates to a light module for a motor vehicle, comprising at least a first row (10) of light sources configured to produce a first output beam (1), and a second row ( 20) of light sources configured to produce a second output beam (2), characterized in that the light sources of the first row (10) and the second row (20) are light-emitting diodes with maximized emissive part, and in that it comprises a primary optical element (30) configured to receive light rays from the sources of the first row (10) and the second row (20), the primary optical element (30) being configured to produce a reflection internal light rays from the sources of at least one of the first row (10) and the second row (20).
