LIGHTING DEVICE WITH TWO LIGHTING FUNCTIONS PROVIDED BY THE SAME GROUP OF LIGHT SOURCE (S) ASSOCIATED WITH GUIDING MEANS

摘要

A lighting device (D) comprises a first screen (E1) provided with a rear face (FR1), at least one reflector (Ri) capable of transferring photons to the rear face (FR1) of the first screen (E1) for participating in a first illumination function, at least one light source (SLi) capable of delivering the photons, a second screen (E2) provided with a rear face (FR2), and guiding means ( MG) adapted to collect a portion of the photons and guide them to the rear face (FR2) of the second screen (E2) so that they participate in a second illumination function.
