Abstract

Module de rétroéclairage comportant un boîtier (10) présentant une ouverture, une lampe (20) montée dans le boîtier, et un panneau avant obturant l'ouverture du boîtier (10). Un axe X désigne l'axe longitudinal de la lampe (20) ; un axe Y désigne un axe perpendiculaire à l'axe X et parallèle au panneau avant ; et un axe Z désigne un axe perpendiculaire à l'axe X et à l'axe Y ; le panneau avant étant pourvu d'une feuille réfringente (13) qui transmet la lumière émanant de la lampe (20) en la réfractant, et d'une feuille de diffusion/collecte conçue pour diffuser et collecter la lumière émanant de la feuille réfringente (13). La feuille réfringente (13) transmet la lumière incidente en la réfractant, de façon à ce que l'inégalité θ1 > θ2 soit vérifiée, θ1 étant l'angle d'incidence de la lumière sur une surface dans le plan Y-Z, θ2 étant l'angle de réfraction, et θ1 > 0. Appliquée à une source lumineuse constituée d'un petit nombre de lampes, l'invention permet d'obtenir un éclairage uniforme.
