Abstract (en)
[origin: US2019078752A1] A lighting device, in particular for a motor vehicle, including a substrate; light sources of the side-emitting LED type, which are placed on the substrate and which illuminate in main directions that are orientated along the substrate; and a screen placed so as to receive the light rays emitted by the light sources. The substrate includes windows and the lighting device furthermore includes reflective surfaces that are placed facing the windows so as to reflect, toward the screen, a portion of the light rays emitted by the light sources.
