Description

ABSTRACT:
At least one amalgam, which is disposed within the lamp envelope of an electrodeless fluorescent lamp to control mercury vapor pressure, is mechanically supported by an amalgam support arrangement in a manner non-invasive to the lamp envelope. The amalgam support arrangement supports one or more amalgams in a "flag" configuration and includes a support member, one end of which is configured for friction-fitting within the exhaust tube opening. The flag may be configured as a wire mesh or spiral-shaped wire, for example. Exemplary configurations for this end of the support member include a U-shape, spiral, zig-zag, or tubular configuration.
