Abstract

Le problème à résoudre est de produire un dispositif d'éclairage apte à fournir une quantité uniforme de lumière par un élément guide de lumière. A cet effet, l'invention porte sur un dispositif d'éclairage (X1) qui comprend : un élément guide de lumière (1) dans lequel de multiples guides de lumière (3a, 3b), qui comprennent des sections de sortie de lumière (9a et 9b) qui délivrent de la lumière et des sections de réflexion (11a, 11b) qui sont agencées du côté opposé par rapport aux sections de sortie de lumière (9a, 9b), sont raccordés au niveau d'une section de raccordement (8) de manière à ce que les sections de sortie de lumière (9a, 9b) des multiples guides de lumière (3a, 3b) soient continues; et des éléments électroluminescents (7a, 7b) qui sont agencés aux deux extrémités de l'élément guide de lumière (1) et fournissent de la lumière à l'élément guide de lumière (1). Une section d'absorption de lumière (5) et/ou une section de diffusion de lumière (10) sont installées dans la section de raccordement (8), les sections de réflexion (11a, 11b) au voisinage de la section de raccordement (8) et/ou les sections de sortie de lumière (9a, 9b) au voisinage de la section de raccordement (8).
