Abstract
Illuminator apparatus and reflective optical methods directed to meeting the stringent requirements of surgical lighting and similar requirement uses. In the optical system, axially symmetrical light source means and multiple reflectors project light rays in a converging light pattern of uniform light intensity. The angled approach of light to the illuminated area reduces shadow formation and forms a shadow-free zone for location of fixture handling and pattern controls. Heat projection is reduced or minimized optically and the physical arrangement of the support structure provides for removal of heat from the area. Color correction, if required, can be achieved optically without relying on increase in or control of source intensity.
