Claim:
1. A lighting system comprising: a housing having a three-dimensional, non-planar interior volume at least partially enclosed by an interior surface, wherein a first portion of the interior volume has a first curvature; and a flexible light sheet comprising (i) a flexible substrate having first and second opposed surfaces, (ii) a plurality of light-emitting elements disposed over at least one of the first or second surfaces of the substrate, and (iii) a plurality of conductive traces disposed on the substrate and electrically interconnecting the plurality of light-emitting elements, wherein, when the light sheet is in an undeformed configuration, (a) the light sheet is substantially planar and (b) the light-emitting elements of the light sheet collectively emit light having a first spatial optical characteristic, wherein (i) the light sheet is disposed within the interior volume of the housing, (ii) the light sheet is deformed to conform to the interior volume of the housing, (iii) the light-emitting elements of the light sheet collectively emit light through the housing with a second spatial optical characteristic different from the first spatial optical characteristic, and (iv) only one or more portions, but not the entirety, of the light sheet are in contact with the interior surface such that a portion of the light sheet, disposed within the first portion of the interior volume, is deformed to have a second curvature different from the first curvature.
