ABSTRACT:
An axial spotlight system, including an axially mounted arc lamp in an ellipsoidal reflector. The usually associated thermal problem at the forward terminal of the lamp is eliminated by a metal mounting frame which connects the terminal to the reflector and thereby performs as a heat sink for the lamp to avoid deterioration of the forward terminal. To further limit problems at the forward terminal of the lamp a lead wire is permanently affixed thereto and accurate focusing of the lamp is accomplished by means of the metal mounting frame holding the front of the lamp and an adjustment assembly holding the back of the lamp.
