Lamp and getter for removing gaseous impurities

摘要

The present invention has a lamp/getter assembly which reduces or eliminates mechanical and chemical wearing of the filament/leads in a lamp. One or more getters are formed across the filaments of the lead wires of a lamp during construction. During the cooking and sealing off process, the mechanical integrity of the lead wire/filament geometry is maintained by the effect of the getter structure. After the sealing process, the lamp is operated at lower than operating voltage and the getters operate to remove impurities. When the lamp is then operated at normal voltage and temperature, the getter melts and breaks.
