Abstract:
1. An LED-driven luminaire arrangement, comprising: a) an elongated, single, non planar, solid luminaire having non planar side-light emitting portion elongated along a longitudinal axis of said luminaire for emitting light from the side of the luminaire to two non-overlapping target areas; b) the side-light emitting portion being formed by an extractor of light comprising first and second Lambertian light-extraction regions, wherein the first and second light-extraction regions— c) each of the first and second light-extraction regions being spatially divided in segments along said longitudinal axis with gaps between the segments, wherein, with respect to a majority of said segments of each of the first and second light-extraction regions— d) said solid luminaire being free of cladding with a lower refractive index than said solid luminaire; and e) at least one LED for supplying light to the luminaire; and f) a non-imaging collector for coupling light from the at least one LED into the luminaire.
