Abstract
The electric lamp comprises a lamp vessel ( ) and an electric element ( ). The electric element ( ) is electrically connected to the outside via a current feedthrough ( ) which comprises a molybdenum gauze as a metal sealing part ( ). The risks of too strong oxidation of the metal sealing part and of excessive tensile stresses in the seal are both decreased when the molybdenum gauze ( ) is used, hence the safety of the lamp is increased.
