    Abstract: The present invention introduces a new class of thin doubly collimating light distributing engines for use in a variety of general lighting applications, especially those benefiting from thinness. Output illumination from these slim-profile illumination systems whether square, rectangular or circular in physical aperture shape is directional, square, rectangular or circular in beam cross-section, and spatially uniform and sharply cutoff outside the system's adjustable far-field angular cone. Field coverage extends from +/?5- to +/?60-degrees and more in each meridian, including all asymmetric combinations in between, both by internal design, by addition of angle spreading film sheets, and angular tilts. Engine brightness is held to safe levels by expanding the size of the engine's output-aperture without sacrifice in the directionality of illumination. One form of the present invention has a single input light emitter, a square output aperture and the capacity to supply hundreds of lumens per engine.
