Abstract:
A planar fluorescent lamp equipped with flat electrodes comprising:a lamp housing having a bottom panel and integrally formed side panels extending upwardly away from and along a peripheral edge of said bottom panel, said bottom panel having an inner surface of a corrugated structure formed linearly parallel to two of said opposing side panels, said side panels having a height substantially similar to a thickness of said planar fluorescent lamp, a cover plate having planar top and bottom surfaces each having a surface area substantially the same as the planar surface area of said bottom panel, said bottom surface of the cover plate being spaced-apart from said corrugated inner surface of said bottom panel sealingly engaging said side panels on said lamp housing forming a vacuum tight cavity therein, a fluorescent coating layer on a top surface of said planar bottom panel and said bottom surface of said cover plate, and a pair of flat electrodes each formed in an elongated rectangular shape and positioned in said vacuum tight cavity juxtaposed to one of two opposing side panels for forming a substantially uniform electric discharge field in said cavity.
