Abstract (en)
[origin: DE102005035779A1] Electrical lamp with an outer bulb comprises a sealed vacuum-tight long inner bulb (30) containing a light (2) with foils through the seal (31) at opposite ends. The outer bulb has two narrowed neck ends (36) over the inner bulb and connected to the seal. The distance between the seal and neck is preferably at least 2.5 mm and this distance to the inner bulb is held so that the narrow region of the neck encloses at least 40% of the axial length of the foil. An independent claim is also included for a production process for the lamp above.
