<p>A light source for a flat panel display or luminaire includes a tubular enclosure (21) having a linear slit (25) in which is positioned a lens structure 4 which may be a cylindrical rod (24) or a plurality of ball lenses (42). The lens, whether a rod or ball structure, has an opaque white reflective strip or scoating (27) facing inward of the tubular enclosure, thereby defining two narrow slit openings (22) through which the light can be projected into the lens structure and into an associated waveguide (31).</p> |
