Abstract: A lamp (10), which can be used in rapid thermal processing (RTP), has a lamp envelope (12) arrayed along a longitudinal axis (14) and has a top (16) and a bottom (18). A first coiled-coil filament (20) having a first lead-in (20a) and a second coiled-coil filament (22) having a second lead-in (22a), are parallelly arrayed to each other and to the longitudinal axis (14) within the envelope (12). A serial connector (24) joins the first and second filaments; and an electrically insulating support (26) is positioned near the bottom (18) of the lamp envelope (12). The first lead-in (20a), the second lead-in (22a) and at least a portion (24a) of the serial connector (24) are sealed within the insulating support 26 whereby the first and second lead-ins (20a, 22a) and the at least a portion (24a) of the serial connector (24) provide the only support for the first and second filaments (20, 22).

Abstract: A lamp may be formed with radial arm electrical contacts from a ceramic body insulating body supporting a lamp capsule. A press sealed tubular lamp is held in an end of the ceramic body. The radial arms extend sideways from the ceramic body and support electrical contacts, that may be brought into electrical contact in an insert and twist type socket.

Abstract: A lamp (10) includes an integral cooling system (12) and comprises: a quartz envelope (14) including a light-source (16) operating at a temperature above 900° C. A seal (18) closes one end of the quartz envelope and includes electrical lead-ins (20, 2) for electrical connection to the light-source (16). A ceramic base (24) is affixed to the seal (18) on only two sides (26, 28) thereof. The base (24) includes a circumferential bottom (30) with upstanding walls (44, 46) and includes a pair of contacts (32, 34) connected to the lead-ins (20, 22); and an air passage (36) between the circumferential bottom (30) and the seal (18).

Abstract: A lamp (160) comprising: a light-emitting lamp capsule (161) arrayed about a longitudinal axis (161a); a base (162) supporting said lamp capsule (161), said base (162) including a peripheral flange (163) extending normal to said longitudinal axis 161a); and electrical contacts (164) attached to said peripheral flange for providing power to said light-emitting lamp capsule (161), said electrical contacts (164) extending from said peripheral flange (163) in a direction parallel to said longitudinal axis (161a).

Abstract: A reversible base for a lamp can reduce the number of parts needed for differing lamp assemblies. The preferred base is an insulating body with a first receptacle for a lamp capsule including a cavity, and a second receptacle. The second receptacle is aligned in opposition to the first receptacle, being similar in size and shape. A support is positioned between an end of the first receptacle and an end of the second receptacle and extends radially from a mid-region between the first and second receptacles. The support includes a radially extending flange having a face and a sidewall. Electrical contacts are held on the support, and may be axially aligned pins extending from the face of the flange. The pins may be electrically extended for coupling in either the first or second receptacle to lamp leads.
