Capped electric lamp with connection conductor butt welded to a lamp vessel current conductor |
摘要 |
The capped electric lamp has a quartz glass lamp vessel (1) with a first neck-shaped portion (2) which is kept fixed by the cap (20). First (4) and second (5) current supply conductors (4, 5) emanate from the neck-shaped portions (2 resp. 3) and are connected to contact members (24 resp. 25) of the cap, the second supply conductor (5) via a connecting conductor (7). The joint of the connection conductor (7) to a molybdenum end portion (5a) of the second supply conductor (5) is a butt weld (9). The joint is solid and reliable. An insulator tube (8) may be present around the connection conductor (7) and fixation means (10, 11 ) may be present to immobilize the tube.
