ABSTRACT:
A glass rod extending through and sealed to the exhaust tube of an electrodeless SEF fluorescent discharge lamp has a metal support member at one end thereof for supporting an amalgam at or near the apex of the lamp envelope. The metal support member may comprise a spiral-shaped wire, a wire screen, or a wire basket. Preferably, the amalgam is maintained in contact with the apex of the lamp envelope. If desired, the metal support member may comprise a magnetic material to allow for magnetic transport of the amalgam assembly during lamp processing. The metal support member restricts spreading of the amalgam when in a liquid state; and the glass rod provides rigid support for the amalgam independent of lamp orientation.
