Abstract

La présente invention concerne un système optique. Le système optique comprend un élément optique de collimation de lumière, un boîtier et un réseau de diodes électroluminescentes, DEL. Le boîtier loge l'élément optique de collimation de lumière et comporte une paroi interne d'absorption de lumière. Le réseau de DEL est configuré pour émettre de la lumière dans l'élément optique de collimation de lumière. Le réseau de DEL comprend un premier ensemble de DEL composé d'une ou de plusieurs DEL agencées de manière centrale et un autre ensemble de DEL composé d'un agencement de DEL agencées autour du premier ensemble de DEL. Le réseau de DEL est agencé au niveau d'une première ouverture du boîtier.
