A lighting system uses an edge lit waveguide. The bottom has a set of elongate light extraction features for out-coupling light from the light guide towards a reflector which reflects light back into the light guide. The top face of the light guide functions as the output for the lighting system. In some examples it has a set of elongate beam shaping features extending substantially orthogonally to the set of light extraction 5 features for beam shaping of light exiting the top face. |
