High-pressure discharge lamp |
摘要 |
A high-pressure discharge lamp having a hydrogen getter in the lamp vessel disposed in a metal envelope which is hydrogen-permeable. The hydrogen-permeable metal of the envelope is covered with a porous halogen-resistant layer. The atoms of the metal halides dissociated in the discharge can recombine at the porous layer so that blackening of the discharge vessel is mitigated.
