Abstract: A high-pressure discharge lamp having a glass enclosure defining a discha space and envelope portions extending away from the discharge space is provided with elongate electrode portions extending respectively through the envelope portions. These electrode portions carry respective electrode portions at their inner ends and the electrode portions are sealed hermetically to the respective envelope portions. In order to support the electrode portions within the envelope portions, respective support elements are fitted around the electrode portions in spaced relation to the envelope portions and means, including a respective resilient element engaging each support member, are provided to hold the support elements in their axial position around the respective electrode portions.

Abstract: A high-pressure electric discharge lamp comprises a support part surround each electrode rod, each electrode rod having a spring wound therearound and pressing the respective support part toward an electrode mounted at the end of the respective electrode rods. This arrangement comprises a part of an assembly which is then mounted into envelope necks which extend from respective opposite ends of a quartz glass envelope which defines the discharge space of the lamp. A narrowing area is defined at the transition of the envelope necks to the envelope, the supporting parts each having a rounded end resting against a respective inclined surface defined by the narrowings at the transitions between the envelope necks and the envelope. The springs resiliently bias the supporting parts against the inclined inner surfaces of the narrowings. Also disclosed is a method of manufacture of the above described high-pressure electric discharge lamp.
