Abstract

The production of a low pressure mercury vapour discharge lamp is based on a lamp tube provided with an evacuation tube, in which the quantity of mercury, required for operation, is contained in a container in the evacuation tube. The latter is heated after the evacuation, and possible gas filling, to such extent that the container opens under the force of the mercury vapour pressure produced by the heat. The container is mostly flat and so arranged in the evacuating tube that the normal evacuation and filling is not impaired. The container is preferably formed by two metal parts welded together, at least one having a dishing containing the metallic mercury prior to heating.
