Abstract

PURPOSE: To provide a process for preparation of discharge lamps such as metal halide lamps in which a metal halide or the like incorporated and sealed in a tube is vacuum-deposited in the vicinity of an electrode to prevent devitrification of the central portion of the emission tube and improve the luminous flux maintenance ratio of the discharge lamp.
