Abstract

L'invention concerne un appareil et un procédé s'appliquant à une source de lumière. L'appareil comprend un guide de lumière comprenant des éléments d'extraction de lumière et au moins une source de lumière placée à côté d'une extrémité du guide de lumière. La lumière provenant de la source est déviée par les éléments d'extraction de lumière et émane selon une configuration prédéterminée le long d'une surface du guide de lumière. Le guide de lumière présente différentes épaisseurs dans différentes parties.
