HIGH PRESSURE ELECTRIC DISCHARGE DEVICE WITH ZIRCONIUM-ALUMINUM GETTER

摘要

Strips of zirconium-aluminum are disposed within a high pressure metal iodide discharge lamp to getter hydrogen which is entrapped therein. The strips are welded to support straps on each of the arc tube press seals to thereby dispose the getter at each end of the lamp at locations where the operating temperature will be maintained at about 500 DEG C.
