Abstract
"IMPROVEMENTS INTRODUCED IN LOW PRESSURE METAL STEAM DISCHARGE LAMPS", belonging to the genus in which the arc tube, in which the discharge takes place between distanced electrodes that emit electrons, is enclosed in an external receptacle permeable to the light, hermetically closed and in which a vacuum has been made, which serves to isolate the arc tube from the atmosphere. The arc tube may contain a vaporizable metal such as sodium, cadmium, or zinc together with a rare gas such as neon and/or argon and xenon. The function of the rare gas is to sustain an initial discharge between the electrodes during the rise of the arc tube temperature and the resulting vaporization of the vaporizable metal to a point where it can contribute to the electrical conductivity of the discharge, and in doing so thus, supplying the light output of the lamp.
