Abstract
The capped electric lamp of the invention has a ceramic cap (10) having a shell portion (12) and an integral base portion (11) through which metal pins (13) pass. A lamp vessel (1) having a seal (4), from which current conductors (3) to an electric element (2) within the lamp vessel extend beside one another to the exterior, is fixed in the cap (10). Outside the lamp vessel the current conductors (3) each have a portion sealed in a glass envelope (6) which is connected to the seal. The glass envelopes (6) define a slit (5) between them. A ceramic partition wall (20) having a foot (21) is fixed on the base portion (11) and extends into the slit (5), thereby creating for the current conductors and respective contact members connected thereto their own compartment (14) in the cap. The lamp cap (10) and the partition wall (20) are readily obtainable and easy to assemble and nevertheless allow for high voltages to be used to ignite or to hot restrike the lamp.
