Abstract

Un dispositif d'éclairage (DE) comprend des sources de lumière (SL) générant des photons et un guide de lumière (GL) pour transférer les photons alimentant une face d'entrée (FS) d'une zone arrière (ZR) vers une face avant (FV) en vue de leur transfert vers l'extérieur pour assurer une fonction photométrique. Ce guide de lumière (GL) comprend, en des endroits prédéfinis situés entre les zone arrière (ZR) et face avant (FV) et fonction des positions respectives des sources de lumière (SL) par rapport à la face d'entrée (FS), au moins deux trous (TR) ayant chacun une forme générale polygonale définie par des parois (PT) propres à réfléchir vers la face avant (FV) ou vers une paroi (PT) d'un autre trou (TR) certains des photons en cours de transfert, pour assurer avec d'autres photons transférés mais non réfléchis par un trou (TR) un éclairage sensiblement homogène participant à la fonction photométrique.A lighting device (DE) comprises light sources (SL) generating photons and a light guide (GL) for transferring the photons supplying an entrance face (FS) from a rear zone (ZR) to a front face (FV) for their transfer to the outside to ensure a photometric function. This light guide (GL) comprises, at predefined locations located between the rear zone (ZR) and front face (FV) and depending on the respective positions of the light sources (SL) with respect to the entrance face (FS) , at least two holes (TR) each having a generally polygonal shape defined by walls (PT) able to reflect towards the front face (FV) or towards a wall (PT) of another hole (TR) some of the photons in transfer course, to ensure with other photons transferred but not reflected by a hole (TR) a substantially homogeneous illumination participating in the photometric function.
