Abstract
L'invention a trait à un module lumineux (1) comprenant au moins deux guides optiques (2, 2') superposés où chacun des guides comprend deux faces de guidage opposées correspondant aux deux faces principales de la plaque, aptes à guider la lumière par réflexion totale et des structures sur une des deux faces de guidage, formant des dioptres aptes à réfléchir vers la face de guidage opposée une partie des rayons provenant de la ou des sources lumineuses. Chacun des guides (2, 2') comprend au moins deux faces d'entrée de lumière (8, 8' ; 12, 12') et au moins deux groupes (20, 22 ; 21, 23) des dioptres, les dioptres d'au moins un, préférentiellement de chacun, des groupes étant aptes à essentiellement réfléchir exclusivement au moins une partie des rayons incidents provenant d'une des faces d'entrée associée audit groupe.
