ABSTRACT:
A thick-film integrated flat fluorescent lamp consists of a plurality of thick-film integrated split hollow electrodes printed on the inside of two opposing flat glass plates. These plates are sealed together, with a fixed space between them, which is filled with mercury and inert gas. Phosphor is coated on both glass plates and aluminum is preferably coated on one. The split hollow electrode structure produces more uniform brightness from the lamp over the entire area of the lamp, and results in a lamp of long life.
