ABSTRACT:
A major surgical light has a plurality of light sources which permit both color and size adjustment of the illumination pattern. Color variation is accomplished by increasing the intensity of a light source of one color value while decreasing the intensity of a light source of another color value. Size adjustment is accomplished by providing two light sources, each casting different diameter light patterns which are superimposed on the work area. The intensity of one light source is increased while the other is decreased so as to vary the size of the pattern.
