Abstract:
A floor lighting assembly includes a luminous composite sheet and a light transmissive carpet. The luminous composite sheet has a top side, a bottom side, and an edge extending from the top side to the bottom side. The light sources are arranged in a row and are configured to emit light into the light guide film through the edge. The light transmissive carpet is disposed above the top side of the light guide film. The light transmissive carpet includes a backing structure and a pile mounted to and extending from the backing structure. The light guide film is configured to spread and redirect the light that is received therein through the edge for emitting the light through the top side of the light guide film such that some of the light is transmitted through the light transmissive carpet.
