Lamp module for planar source device

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:
• a light inlet surface;
• and
• a light outlet surface,
• 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.

A scanner light source, comprising:

• means for producing non-planar light;
• means for receiving the non-planar light at a light-guiding plate;
• and
• means for reflecting the received non-planar light to enable emitting the non-planar light as planar light from a light outlet surface of the light-guiding plate.
