Abstract The invention pertains to a fiber optic lamp system such as those employed in medical diagnostic systems using a cabinet containing a power supply having a front extendible drawer containing a 250 watt focused beam metal halide arc lamp mounted in a removable bracket which includes a sensing tab extension. The bracket sensing tab operates an electrical interlock switch when the proper lamp is properly installed. The interlock switch controls power to the system whose circuit includes pin and floating sleeve electrical connectors which automatically directly completes the circuit to the arc lamp upon the drawer being closed. The amount of light transferred to the fiber optic cable is optimized by offsetting the axis of focused light with respect to the optic cable axis at the cable interface.
Fiber optic medical diagnostic light source apparatus supplying light to a fiber optic cable interface which is attached to a cabinet having a lamp power supply and a lamp circuit comprising in combination, a lamp bracket holder mounted on the cabinet, a lamp bracket movably supported on said lamp bracket holder, interlock switch operating means defined on said lamp bracket, a focused lamp mounted on said lamp bracket having a beam adapted to be received by the cable interface at a predetermined position of said lamp bracket, and an electric interlock switch controlling energizing of the lamp circuit adapted to be operated by said lamp bracket switch operating means at said predetermined position of said lamp bracket.
