Abstract:
1. An apparatus, comprising: a lamp holder having a curved arc surface, wherein ends of the curved arc surface are at least partially inwardly converging, and wherein the lamp holder is adapted to hold a lamp having a length shorter than a length of the lamp holder and reflect light provided by the lamp over a linear dimension larger than the length of the lamp; and a light-guiding plate coupled to the lamp holder, comprising: wherein the light-guiding plate comprises at least a top reflective surface coupled to a plurality of side reflective surfaces, wherein the top reflective surface is configured at a slope with respect to light outlet surface, and the plurality of side reflective surfaces have a length and a height, wherein the height of one or more of said reflective surfaces varies along the length, and wherein the light guiding plate is adapted to: receive non-planar light at the light inlet surface; and enable the non-planar light entering the light inlet surface and reaching the light emitting surface to emerge as a planar light source.
