Patent ID: 7932665

Claim:
A lamp for use in rapid thermal processing comprising: a lamp envelope arrayed along a longitudinal axis and having a top and a bottom; a first coiled-coil filament having a first lead-in and a second coiled-coil filament having a second lead-in parallelly arrayed to each other and to said longitudinal axis within said envelope; a serial connector joining said first and second filaments at ends remote from said lead-ins, said serial connector having a first end, a second end, and an intermediate portion between the first and second ends, wherein the first end, the intermediate portion, and the second end together define a sequential electrically conductive pathway between the first coiled-coil filament and the second coiled-coil filament; and an electrically insulating support positioned near said bottom of said lamp envelope, said first lead-in, said second lead-in and at least a portion of said serial connector being sealed within said insulating support whereby said first and second lead-ins and said at least a portion of said serial connector provide the only support for said first and second filaments; and a portion of said electrical pathway containing the intermediate portion is sealed in and extends through the insulating support, whereby a path for conduction of electricity is defined along said electrical pathway through said insulating support.
