    Abstract: A low-pressure sodium vapor discharge lamp provided with a discharge tube having an electrical lead-through conductor extending through the wall of the discharge tube to an internal lamp electrode. The lead-through is enveloped by a protective glass layer having a double bead construction. The layer portion facing the electrode is borate glass and is thinner than a second portion within the discharge tube wall which is lime glass. The lead-through construction thus obtained has a high resistance to sodium in the discharge tube and also to mechanical forces.

    Abstract: Various sodium vapor lamp configurations are disclosed. In one, a sodium vapor discharge tube contains an excess of sodium which is condensed in predetermined locations, as for example dimples. To prevent condensation in the aperture through which light emission is desired, the discharge tube is heated at the aperture by ohmic heating of a conductive film such as tin oxide or by fine wires. In a second configuration, the discharge tube is coated on the inside with metallic sodium, the coating being internally reflective and defining an aperture, such as a slit, through which light output is directed. The aperture area is coated with a conductive coating such as tin oxide to provide ohmic heating of the aperture area so that metallic sodium condenses on the tube in areas other than the aperture. Thus, an excess of sodium is provided to control the lamp vapor pressure and also to form a light reflective coating to direct emission through the aperture.

    Abstract: A low-pressure sodium vapor discharge lamp having small reservoirs of sodium positioned near the electrodes in a manner so as to satisfy the condition B/T > OR = 0.5, wherein B represents the overall contents of those reservoirs whose distance up to the nearest electrode is between 10 and 35 percent of half the length of the discharge path and T represents the overall contents of all reservoirs. A heat-reflecting layer is positioned between the outer envelope and the discharge tube and extends over part of the length of the lamp to keep the reservoirs nearest the electrodes at cooler temperatures.
