Short-arc discharge lamp for use as e.g. light source of projector, has hydrogen getter comprising hollow container, and wave-like recesses formed at inner surface of container of getter, where inner surface lies opposite to electrode shaft

The lamp has electrodes consisting of an electrode main body and an electrode shaft. The electrodes are arranged opposite to each other, and a hydrogen getter (4) is attached around the electrode shaft in a coiled manner. The hydrogen getter comprises a tight-closed hollow container (5). A hydrogen...

description The lamp has electrodes consisting of an electrode main body and an electrode shaft. The electrodes are arranged opposite to each other, and a hydrogen getter (4) is attached around the electrode shaft in a coiled manner. The hydrogen getter comprises a tight-closed hollow container (5). A hydrogen absorbing getter material is enclosed at an interior of the tight-closed hollow container, which is made of a hydrogen-permeable material. Wave-like recesses (8) are formed at an inner surface of the hollow container of the getter, where the inner surface lies opposite to the shaft. Die Erfindung betrifft einen Wasserstoffgetter, bei dem ein Wasserstoff absorbierendes Gettermaterial im Inneren eines dicht verschlossenen hohlen Behälters aus einem wasserstoffdurchlässigen Material eingeschlossen ist, wobei der hohle Behälter einen zentralen Hohlraum zumindest teilweise ringförmig umgibt. An der dem zentralen Hohlraum benachbarten Innenfläche des hohlen Behälters sind wellenförmige Vertiefungen gebildet. Die Erfindung betrifft weiterhin ein Verfahren zur Herstellung des Wasserstoffgetters sowie eine Kurzbogenentladungslampe, bei welcher der Wasserstoffgetter an einem Elektrodenstab befestigt ist.
