The inner end of the lead-in conductor is rigidly engaged to the inner end portion of a filament. The other end of the filament extends into the solid base and is therein fixedly joined to the inner end of a lead-out conductor formed of Dumet metal. The said conductors in their outer ends are suitably connected to terminals or posts in a base plug which supports the glass envelope.
