Abstract

PURPOSE:To improve the stability by inserting an emitter into a metal pot where a complex galvanization layer showing an convex/concave surface scattered with a getter material is formed on the inner wall face. CONSTITUTION:A complex galvanization layer 4 is formed on the inner wall face of a metal pot 1 inserted with an emitter 2. A getter materials is scattered in said layer 4 while its surface is made convex/concave. An emitter 2 is mounted in a metal pot 1 where a complex galvanization layer 4 is formed having convex/concave surface is formed on the inner wall face, and when applied with thermal treatment such as sintering, activation, etc. said convex/concave surface of said layer 4 will function effectively to hold the emitter 2. While the getter contained in said layer 4 will catch the impurity gas produced during the usage of the lamp.
