Abstract

Improvements made to electric lamps provided with a central contact and a lateral contact structurally separated from said contact, each of these contacts being connected to one of the power conductors that extend towards the foot, lamps in which the neck is provided with a possibly interrupted printed helical profile, characterized by the fact that a sheet of thin material pressed into this profile and with at least one electrically conductive surface, is provided around the profiled part of the lamp neck, one of the conductors being connected that extend electrically conductively toward the foot to this sheet.
