Abstract:
The oblong bulb (1) of the lamp is sealed at opposing ends by sealing pieces (6; 32), with application of a holder to each end, whereby said holder comprises an electrical contact element (13; 25), electrically connected to a power supply (15; 21), running to the lighting means. The contact element is housed in a tubular extension (11; 22) of the sealing piece and the maximum external diameter of the contact element (13; 25) is loosely matched to the inner diameter of the sleeve.
Abstract:
A high-temperature-resistant composite body is formed by joining over an area of a first, nonmetallic section via a bonding solder layer to a second, metallic section composed of Mo, an Mo-based alloy, W or a W-based alloy. A first arrangement composed of the first section, a first Zr solder and an intermediate layer is firstly soldered together in a first soldering step. A second arrangement of the resulting partial composite body, a second solder adjoining the intermediate layer and the second section is subsequently soldered together in a second soldering step. The intermediate layer at least 90 atom % of at least one of the elements Ta, Nb, W. The second solder is formed by precisely one material selected from Ti, Ti-based solder combination, V-based solder combination, Zr or Zr-based solder combination and it melts at a lower temperature than the first Zr solder in the second arrangement.
