An integrally molded flat fluorescent lamp comprising a convoluted channel member (11) formed of vitreous glass with convoluted channel (14) fabricated by employing a combination of vacuum-assisted sag molding, press molding and blow molding techniques. While the part (11) is molten, a planar member (13) is fused to it by pressing the parts (11 and 13 at 15) together to form a closed glass envelope. The inside of the envelope is coated with a phosphor layer and preferably the external surface of the envelope is coated with a reflective layer. A pair of electron-emissive electrodes are fused to openings (12) in the envelope. They are sealed through glass flares at the two holes integral to the envelope. The envelope is evacuated and filled with a rare gas and mercury to a suitable pressure and sealed off to form a lamp.
An integrally molded, flat compact fluorescent lamp comprising:
An integrally molded, flat compact fluorescent lamp, said lamp having a low weight relative to prior art lamps, said lamp further not employing frit sealing of components whereby to slow manufacturing rate and increase production costs, said lamp comprising:
