Abstract
A flat type fluorescent lamp comprises a molded plate glass in the form of an upside down dished plate and a flat plate sealed to the dished plate along the peripheral portions thereof. A pair of electrodes are mounted on the flat plate glass, spaced from the flat plate glass, through stems or connector pins and are sealed in the fluorescent lamp body. The fluorescent lamp requires no base so that the overall length thereof may be reduced.
