Abstract
A planar photoluminescent lamp having a plurality of internal walls to form a serpentine channel includes a deflection member at a distal end at least portion of the internal walls to force a plasma discharge into a central portion of the channel to thereby provide more uniform lighting at junctions between the turns in the serpentine channel. As a result, the photoluminescent lamp has more uniform brightness. The principles of the present invention may be extend to any photoluminescent lamp having a junction between two channels wherein a guide member serves to guide the plasma discharge toward the center of the channel at the junction.
