Abstract
A mount for an arc discharge lamp has a cathode thereon which is encircled by a disintegration shield. The shield has a narrow gap between its ends with a mercury containing metal capsule in the gap. The lower portion of the capsule is connected to the ends of the shield so that when an Rf current is induced in the shield, it preferentially flows through the lower portion of the capsule.
Claims2
In an arc discharge lamp having a glass mount at one end with a cathode supported on the mount, the improvement comprising a disintegration shield encircling the cathode except for a narrow gap between the ends of the shield, a mercury containing metal capsule disposed in the gap and electrically connected to the ends of the shield, the portion of the capsule that is connected to the ends of the shield being the lower portion thereof which is more proximate the mount so that when an RF current is induced in the shield the current flow through the capsule primarily occurs through said lower portion.
