ABSTRACT:
The capped electric lamp has a metal clamping member which surrounds a longitudinal part of the lamp vessel with a clamping fit and is secured to a metal bushing. The lamp cap has a metal sleeve secured therein which receives the metal bushing with telescoping fit to allow alignment of the lamp vessel with the lamp cap. After alignment, the metal bushing is fixed to the sleeve, for example, by welding. A dimming hood is secured in the aligned state to the bushing. A current-supply conductor extends through a tubular part inside of the lamp cap to a contact member of the lamp cap.
