Abstract:
A lighting device including at least two LED light sources configured for individual activation; at least two light guides arranged adjacent to one another, each including an edge surface facing a respective one of the LED light sources, a back surface extending from the edge surface provided with a plurality of diffuser extractor elements, and a front surface extending from the edge surface and opposite the back surface; and opaque barrier walls provided between the at least two light guides and extending from the rear wall to the front wall, to mechanically and optically separate the light guides. The light guides are configured to receive light from the LED light sources, with the diffuser extractor elements arranged shaped redirect received light traveling within the light guide to be projected through the front surface.
