ABSTRACT:
A process and apparatus reversibly converts an ellipsoidal stage lamp into a projector for projecting light with special effects onto a stage. The apparatus includes a replacement for the shutter section, which is a cabinet for disposition within the ellipsoidal stage lamp to replace the shutter section. The cabinet defines a first opening disposed along and around the optical axis of the ellipsoidal stage lamp and which is open to the base and lamp having a filament. The cabinet has one open side for permitting the sliding insertion of a drawer. The drawer, which is mountable to the cabinet, has a second opening disposed along and around the optical axis of the ellipsoidal stage lamp and open to the base and lamp when the drawer is inserted to the cabinet. A movable projector plane is mounted to the drawer across the second opening for insertion to the cabinet at the open side.
