Abstract

L'invention concerne un intégrateur de lumière composé de quatre panneaux de verre identiques (1), parallélépipédiques, collés les uns aux autres, renfermant ensemble un espace creux ouvert parallélépipédique (6), les côtés intérieurs (2) délimitant l'espace creux étant respectivement divisés en une face miroir (2.1) optiquement active, et une face de collage (2.2) qui présente une rainure (7) s'étendant longitudinalement, agissant comme piège à colle, se joignant à la surface optiquement active (2.1). La surface de collage (2.2) d'un panneau de verre respectif (1) s'appuie indirectement, au moyen d'agent adhésif (9), contre le premier côté longitudinal (4.1) d'un autre panneau de verre (1).
