Claim 19:
20. A lighting fixture with segmented emission, comprising:
a sheet of an optically transmissive material having a first broad-area surface configured for light output, an opposing second broad-area surface extending parallel to the first broad-area surface and configured for light output, a first edge configured for light input, and an opposing second edge;
a first plurality of compact solid-state light sources optically coupled to the first edge;
a plurality of patterned light extraction areas distributed over an area of the sheet of the optically transmissive material and separated from one another and from the first edge by separation areas, at least one of the plurality of patterned light extraction areas comprising a two-dimensional pattern of light extraction features formed in or on the first or second broad-area surface; and
a housing covering the first plurality of compact solid-state light sources and portions of the sheet of the optically transmissive material adjacent to the first and second edges,
wherein a width of at least one of the separation areas is less than a length or width dimension of the at least one of the plurality of patterned light extraction areas and at least 10 times greater than a prevalent spacing distance between the light extraction features within the at least one of the plurality of patterned light extraction areas.
