Abstract
A xenon arc lamp is provided with an improved cathode support. The improvements reduce the number of assembly procedures and parts needed to produce an arc lamp. Such reduces the overall cost of manufacturing. The cathode suspension system is made by starting with a single piece of sheet Kovar material that is formed into a cup. Pieces are cut from the bottom of the cup such that three webs connect the outside ring to the center. The three webs each have a flap that is then folded back 90.degree. to form a rigid strut arm. A tungsten cathode electrode is brazed at the center and apex of the three struts with a sleeve that helps bridge the fillet area.
