Abstract
An operating lamp includes a lamp body for receiving a light source, a first light source housed in the lamp body and adapted for illuminating an illumination area of an operating area, and a second light source housed in the lamp body and adapted for illuminating a central portion of the illumination area. The brightness of the second light source is controllable independently of the brightness of the first light source to enhance the brightness of the central portion of the illumination area.
