Abstract
A planar fluorescent lamp equipped with a pair of flat electrodes and a method for fabricating such lamp are disclosed. In the planar fluorescent lamp, a lamp housing and a cover plate which are both formed of a soda-lime glass can be bonded together to form a vacuum tight seal by glass frit. A pair of flat electrodes and a pair of getter strips are pre-mounted in the cavity of the planar lamp. The pair of flat electrodes run substantially the full width of the interior cavity of the lamp such that a substantially uniform electric discharge field can be formed in the cavity when a RF power is supplied to the electrodes. A bottom panel of the lamp housing may be fabricated in a ribbed structure to improve the rigidity of the bottom panel such that it does not bow in when the cavity is sealed under a vacuum pressure.
