ABSTRACT:
Electric discharge lamps having a ceramic lamp vessel and current leadthroughs of niobium or tantalum cannot be operated in a nitrogen-containing atmosphere or in air due to attack of the current leadthroughs by the surrounding gas.
According to the invention, those parts of the current leadthroughs which during operation have a temperature of more than 500.degree. C and more than 350.degree. C, respectively, are screened from the surrounding gas by means of ceramic mouldings which are connected to the current leadthrough in a gas-tight manner by means of sealing material. As a result of this the lamps according to the invention can be operated in a nitrogen-containing atmosphere and in air respectively.
