ELECTRODE MOUNT, A HIGH-PRESSURE DISCHARGE LAMP USING SAME, AND PRODUCTION METHOD FOR SAME |
摘要 |
To prevent bending of an electrode shaft portion by a method which requires minimum increase in production cost, in an electrode mount for a high pressure discharge lamp. A manufacturing method of an electrode mount for the high pressure discharge lamp includes: a process of subjecting the electrode mount to a heat treatment, the electrode mount including an electrode and a metal foil which are welded to each other; and an oxidation process of producing an oxide on a surface of the electrode shaft portion of the electrode by laser irradiation to form an oxidation portion on the surface, wherein a laser irradiation position is determined such that a whole or part of the oxidation portion is included in a sealing portion of the high pressure discharge lamp when the electrode mount is embedded in the sealing portion. |
