Abstract

Système optique, et élément optique de mise en forme d’un faisceau optique dispositif d’éclairage, de signalisation et/ou à vocation cosmétique, correspondants L’invention concerne un système optique (20) comportant au moins un élément optique de mise en forme d’un faisceau optique (21) présentant un axe optique (A-A), et au moins une source lumineuse configurée pour émettre un flux de rayons lumineux. Ledit au moins un élément optique (21) est destiné à être agencé en aval de ladite au moins une source lumineuse (10), présente une face d’entrée (23) et une face de sortie (25) opposée, la face de sortie (25) comporte une zone centrale (Z0) travaillant en réfraction, et au moins une zone périphérique (Z1) comportant, sur la face d’entrée (23), une pluralité d’éléments prismatiques internes (233) travaillant en réflexion totale. Selon l’invention, la zone centrale (Z0) comporte, sur la face d’entrée (23), un réseau de microlentilles concaves jointives (231). L’invention concerne encore un élément optique de mise en forme du faisceau optique (21) et un dispositif d’éclairage, de signalisation et/ou à vocation cosmétique, correspondants.
