ABSTRACT:
A method for making a fluorescent lamp from a pair of molded, flat glass shells. Substantially semi-circular recesses are formed on each shell on bonding surfaces thereof opposite semi-circular recess formed on the other glass shell, so that when the shells are bonded together, a circular orifice is formed on the lamp. An exhaust tube is provided, and a stem is affixed to an end of the exhaust tube, and an electrode filament and a getter plate are secured to the stem. The shells are bonded together with a glass adhesive and simultaneously therewith, the exhaust tube is sealed into the orifice so that the getter plate and the electrode filament thereof are disposed within the space between the bonded shells. The gases within the space between the shells are exhausted and mercury and an inert gas are injected into this space. The exhaust tubes then are sealed.
