ABSTRACT:
A mount for an arc discharge lamp has a cathode thereon which is encircled by a disintegration shield. There is a gap in the shield and a mercury-containing glass capsule disposed proximate the gap. The capsule is supported on the shield by means of an axial wire in the capsule extending beyond both ends of the capsule and welded to the shield. A crack in the glass permits the mercury in the capsule to develop a vapor pressure in the lamp.
