Patent ID: 8783898

Claim:
A suspended light fixture comprising: at least one light source comprising a linear array of light emitting diodes (LEDs) along a first direction; a lightguide that is operable to receive light from the at least one light source at a first location on the lightguide, and to contain the light in a total internal reflection condition within a substantially non-scattering region thereof, and has a curvature along a second direction transverse to the first direction, that results in the lightguide having a concave shape relative to the nadir when the light fixture is suspended; at least one light extraction region optically coupled to the lightguide and along the curvature, that disrupts the total internal reflection condition to extract at least some of the light as output light; and wherein the curvature of the lightguide, in the at least one light extraction region, directs portions of the output light away from the nadir, to provide a ratio of peak luminance to luminance at nadir in an output plane orthogonal to the first direction that is greater than or equal to 1.2.
