Abstract

L’invention concerne un panneau lumineux (10), par exemple dalle d’éclairage pour faux-plafond, comprenant un réceptacle (12) délimitant les dimensions extérieures du panneau (10) comprenant une source lumineuse (20) d’éclairage ayant un spectre d’émission prédéfini (S), une paroi frontale (14A) délimitant une fenêtre de transmission (16) de la lumière émise par la source (20) au travers de la paroi frontale (14A) et un filtre décoratif (60) illustrant une image au travers duquel passe la lumière. La transmission T(l) du filtre (60) à une longueur d’onde l étant donnée par le rapport entre l’intensité I(l) du flux lumineux transmis par le filtre (60) et l’intensité Io du flux lumineux incident sur le filtre (60), l’image comprend une composition de régions colorées définie de telle sorte que la transmission T(l) du filtre (60) est sensiblement constante sur au moins un intervalle (L) de longueurs d’onde compris entre 450 et 650 nanomètres avec une variation inférieure à 10%.
