1. A luminaire comprising:

  • first and second light guide layers optically coupled together by at least one optical coupler, which allows the passage of light from the first to the second light guide layer, the at least one optical coupler comprising an edge coupler for coupling adjacent edges of the first and second light guide layers, the adjacent edges being parallel to a longitudinal axis of the first light guide layer;

    a plurality of light sources, each light source being arranged such that light emitted by the light source is coupled into the first light guide layer at an interface surface arranged substantially perpendicularly to the longitudinal axis of the first light guide layer so that the light travels substantially in a direction parallel to the longitudinal axis of the first light guide layer; and

    a scattering element adapted to cause light to be emitted from an emitting surface of the second light guide layer.
