Abstract

L'invention concerne un dispositif optique et une pièce optique pour la restitution ciblée de lumière diffusée par des sources lumineuses de diodes électroluminescentes (6). Le dispositif optique comprend au moins deux pièces dont une est une première pièce optique (10) sous forme de corps solide conducteur de lumière, l'autre pièce servant à la liaison avec la source lumineuse de diodes électroluminescentes (6). Dans un système de coordonnées cartésiennes, la première pièce optique (10) a une extension longitudinale en direction y inférieure ou égale à l'extension longitudinale en direction z et inférieure ou égale à l'extension longitudinale en direction x. Une ligne enveloppante de la première pièce optique (10) projetée sur un plan x-y donne sensiblement un rectangle. A partir d'un plan x-y, la pièce optique (10, 10') diminue en direction z au maximum pour atteindre 1/4 de la plus grande largeur mesurée par y (By, max), les flancs y-z de la pièce optique (10, 10') ayant une forme quelconque.
