Abstract
L'invention porte sur un dispositif lumineux émettant de la lumière (10) qui présente une distribution de luminance uniforme sur la surface de sortie de lumière d'une plaque de transmission diffuse et qui permet de réduire la consommation d'énergie tout en conservant un angle de visualisation large. Le dispositif émettant de la lumière (10) comporte une source de lumière de surface (12) qui présente une surface émettant de la lumière (20a), un réflecteur (16) et une plaque de transmission diffuse (14). Le réflecteur (16) a une ouverture de fixation de source de lumière (24), une ouverture de sortie de lumière (26) à laquelle la plaque de transmission diffuse (14) est attachée, et un plan de réflexion (28) sous forme de paraboloïde de révolution défini par une parabole (P) avec un axe optique L de lumière émis à partir de la source de lumière de surface (12) en tant qu'axe de révolution.
