Abstract (en)
[origin: EP1201872A2] The device has a translucent optical element(s) with a flat input side and an output side bounded by a first curved surface and at least a second surface. Light incident in a first range is concentrated on the second boundary surface; light incident in a second range emanates from element via the first boundary surface. The second boundary surface is also continuously curved; the boundary surfaces are joined seamlessly with continuous curvature. The device has at least one translucent optical element with a flat light input side and alight output side bounded by a first curved boundary surface and at least a second boundary surface. Light incident in a first angular range is concentrated on the second boundary surface and light incident in a second angular range emanates from the optical element via the first boundary surface. The second boundary surface is also continuously curved and the boundary surfaces are joined seamlessly and with a continuous curvature.
