LIGHTING DEVICE WITH LIGHT GUIDE MOUNTED ON A SUPPORTING PART INCORPORATING A TRANSPARENT MAGNIFICATION SCREEN

摘要

A lighting device (DE) comprises:a support plate (PS1) provided with light sources (SL),a light guide (GL) of flat type and comprising a guiding part (PG) placed between rear (PR) and front (PV) parts, the rear part (PR) supplying photons with the guiding part (PG). , and the front part (PV) delivering the guided photons to the outside, anda support piece (PS2) comprising first (F1) and second (F2) faces to which the support plate (PS1) and the light guide (GL) are fixedly secured, and a transparent screen (ET) projecting on the second face (F2) in front of the front part (PV) and extending over a height strictly greater than the thickness of the light guide (GL) so as to be backlit by the photons delivered by the front part (PV) to ensure a predefined photometric function.
