METHOD OF MANUFACTURING A LAMP

摘要

Method of manufacturing a lamp comprising a transparent vessel containing a gas filling, a luminous element or an electrode extending inside the vessel and connected to a lead wire extending through a pinched portion of the vessel, which lead wire is provided with a protective coating obtained by applying a liquid to the outside of the pinched portion where the lead wire extends from said pinched portion, characterized in that said liquid is a solution of a compound comprising a positive ion of a material chosen for its propensity to react with oxidized lead wire material so as to form the protective coating.
