  • Patent number: 4101796
    Abstract: In high-pressure discharge lamps an electrode pin is provided with a closed cavity extending in the longitudinal direction and in which a hydrogen getter is present. The end of the electrode pin extending in the discharge vessel is formed by a metal part of a hydrogen-permeable metal which bounds the cavity.This construction provides a solution for the contradictory requirements which have to be imposed upon the arrangement of a getter with a hydrogen-permeable envelope. The construction furthermore provides a hydrogen getter with both a high reactivity and a great capacity.
