Abstract

L'invention concerne un dispositif d'éclairage doté d'un corps principal de dispositif qui présente une section en forme de plaque comprenant un matériau non transparent, une unité à source de lumière principale qui est disposée sur le côté de la surface de la section en forme de plaque et une unité à source de lumière auxiliaire qui est disposée sur le côté arrière de la section en forme de plaque et qui est munie de sources de lumière linéaires. Les sources de lumière linéaires sont disposées dans des positions ayant des niveaux de décalage (h1, h2) différents de la surface arrière de la section en forme de plaque (5). Chaque source de lumière linéaire est constituée d'un réseau d'une pluralité d'éléments électroluminescents. De plus, les sources de lumière linéaires qui ont un niveau de décalage (h1) plus grand de la surface arrière de la section en forme de plaque comprennent plus d'éléments électroluminescentes présentant le rendement d'émission lumineuse le plus élevé que les sources de lumière linéaires qui ont un niveau de décalage plus petit de la surface arrière de la section en forme de plaque.
