A light output arrangement comprises a bendable light-outputting layer 51, e.g. a light-guide, and a bendable light-directing layer 50, e.g. a lens array. The layers are fixed together, preferably at a mid-point, so as to prevent relative lateral movement but otherwise are constrained to bend in conformance with each other, preferably maintaining a constant spacing. The light-directing layer comprises a plurality of structures, for example lenses 81, which may cooperate with light extraction features 80 in the light guide so as to direct light output from the light-directing layer in substantially the same direction, 82, 83, irrespective of bending of the layers. |
