Abstract

A method of gas filling and hermetically sealing an electric incandescent lamp a discharge tube or the like, a method in which the interior of a lamp or tube not yet closed is traversed by a stream of an inert gas (eg, nitrogen) under excessive pressure so that at least the ambient air can not penetrate the lamp or tube, maintaining said circulation current until the lamp or tube is hermetically sealed; characterized in that method, that before the sealing operation a quantity of an inert and relatively precious rare gas (such as, for example, xenon or krypton) is introduced into the lamp or tube, said gas condensing in a portion of the wall cooled, for example, with liquid nitrogen, inside the lamp or tube, gas that remains inside the lamp or tube during the sealing operation.
