Abstract

L'invention porte sur une structure d'éclairage, qui est apte à éclairer un panneau de matériau de construction et à améliorer la sensation de luminosité dans une pièce, même quand un dispositif d'éclairage est positionné dans le raccord entre des panneaux de matériau de construction. Dans une structure d'éclairage, un dispositif d'éclairage (1) est positionné au niveau d'un raccord (50) entre un premier panneau de matériau de construction (60A) et un second panneau de matériau de construction (60B) qui comportent chacun une première surface et une seconde surface sur le côté opposé vis-à-vis de la première surface, et qui sont positionnés d'une manière telle que les premières surfaces de ceux-ci sont orientées dans la même direction, le dispositif d'éclairage long (1) ayant une partie lentille (31) et une unité d'éclairage (2) qui contient une source d'éclairage (11). La partie lentille (31) est : formée le long du raccord (50) de façon à faire saillie vers l'extérieur à partir de la première surface (60a) du premier panneau de matériau de construction (60A) et de la première surface (60a) du second panneau de matériau de construction (60B) ; et configurée de façon à provoquer la réflexion d'une partie de la lumière venant de la source de lumière (11) et sa direction vers le premier et/ou le second panneaux de matériau de construction (60A), (60B).
