Abstract

Un dispositif d'éclairage (DE) comprend : - une source de lumière (SL) générant des photons, - des moyens de guidage (MG) propres à guider les photons générés, - une plaque (PSj) ayant une face plane (FP), dans laquelle sont enterrés les moyens de guidage (MG), et comprenant une tranche (TP) recevant les photons générés pour alimenter les moyens de guidage (MG), et - des moyens d'émission (ME) enterrés dans la plaque (PSj) en des endroits choisis situés à proximité des moyens de guidage (MG) et agencés pour produire des photons par couplage avec des photons guidés et réémission, et pour délivrer ces photons produits à l'extérieur de la plaque (PSj), via la face plane (FP), sous la forme de faisceaux collimatés et ayant des intensités sensiblement identiques.
