Abstract

Un dispositif d’éclairage (DE) comprend : - des première (S1) et deuxième (S2) sources délivrant des premiers et deuxièmes photons devant participer à des première et deuxième fonctions photométriques, et - un guide de lumière (GL) comportant une face arrière (FR) comprenant des première (PR1) et seconde (PR2) parties recevant les premiers et deuxièmes photons délivrés, une face avant (FV), et une partie interne (PI) comprenant un élément réfléchissant (ER) s’étendant entre les faces arrière (FR) et avant (FV) en la subdivisant en première (PI1) et seconde (PI2) parties et empêchant des premiers photons circulant dans sa première partie (PI1) de passer dans sa seconde partie (PI2), et des seconds photons circulant dans sa seconde partie (PI2) de passer dans sa première partie (PI1), afin que les premiers et deuxièmes photons soient délivrés à l’extérieur par des première (PV1) et seconde (PV2) parties de la face avant (FV).
