Electrical lamp manufacturing method involves producing pinch seal between foil and quartz glass tube, where area of quartz glass tube is heated and squeezed subsequently in vicinity of foil

摘要

The method involves arranging ceramic removing container with two ends in an outer piston. The free ends of a power supply line (4) are connected with the free ends of the foil. A pinch seal is produced between a foil and a quartz glass tube, where the area of the quartz glass tube is heated and squeezed subsequently in the vicinity of the foil. Another pinch seal is produced subsequently between another foil and another quartz glass tube, where the area of the later quartz glass tube is heated and squeezed subsequently in the vicinity of the later foil.
