摘要： The tubular ceramic discharge vessel of electric discharge lamps is sealed according to the invention with a cylindrical and an annular ceramic moulding between which a tubular current leadthrough member is accommodated consisting of tungsten, molybdenum, rhenium or alloys thereof. The current leadthrough member is connected in a vacuum-tight manner to the two ceramic mouldings by means of sealing ceramic.

摘要： A high-pressure sodium vapor discharge lamp which is provided with a discharge tube and an outer envelope which envelopes this tube.In accordance with the improvement there are disposed in the space between the discharge tube and the outer envelope both a capacitor and a glow discharge starter which are both in parallel with the discharge tube. Consequently an external lamp starter is superfluous. In addition the lamp base may be relatively small.

摘要： 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.
