Hydrogen-gas discharge lamp

摘要

A hydrogen discharge lamp has a glass lamp enclosure formed with a radiation-emitting window and receiving a body of a zirconium-cobalt alloy forming in part a hydride which constitutes a reservoir for hydrogen or deuterium and enabling controlled liberation of the hydrogen or deuterium from the reservoir. The zirconium-cobalt alloy simultaneously forms a getter for elements interfering with spectral purity of a hydrogen discharge emission from the lamp. An electrical discharge is effected in the hydrogen or deuterium liberated in the enclosure to cause the emission of light through the window.
