LIGHT-EMITTING VESSEL AND LIGHT-EMITTING VESSEL FOR HIGH-PRESSURE DISCHARGE LAMP

摘要

A luminous container 1A has an electrode supporting member 8 composed of a plate-shaped metal piece. The electrode supporting member 8 has a clamped portion 8b pressed and clamped with and non-clamped portions 8a and 8c not clamped with a brittle material. The stress generated along a contact interface of the clamped portion 8b and the brittle material is relaxed with the deformation of the electrode supporting member 8.
