Abstract
A light source for a flat panel display or a luminare includes a tubular enclosure having a linear slit in which is positioned a lens structure which may be a cylindrical rod lens or a plurality of ball lenses. The lens, whether a rod or ball structure, has an opaque white reflective strip or coating facing inward of the tubular enclosure, thereby defining two narrow slit openings through which the light can be projected into the lens structure and into an associated waveguide.
