Summary:A high intensity arc discharge lamp having an elongated outer vitreous envelope sealed by a dome at its upper end and a base assembly at is lower end. An elongated arc discharge tube within the envelope is supported at its lower end by the base assembly and at its upper end by a supporting frame, the lower end of the supporting frame also being supported by the base assembly. To stabilize the upper end of the supporting frame against movement with respect to the outer envelope, a curvilinear flat retaining spring is affixed at one end to the upper end of the supporting frame, the other end of the retaining spring being in free cantilevered compression contact with the dome of the envelope.
