Abstract

An improved mercury vapor discharge lamp including a lamp vessel having an evacuation tube and whereby the amount of mercury, in metallic form, required for lamp operation is present in a closed metal container, arranged in the evacuation tube, the container of which, after pumping the lamp, is heated to a temperature such that it opens due to the accumulation of mercury vapor pressure in it, characterized in that the plate-shaped container is in the longitudinal direction of the evacuation tube.
