A reflector for dental and surgical operating room light fixtures exhibits, in a first cutting plane, an elliptic contour. A parabolic contour is exhibited in a second cutting plane vertical to this first cutting plane. The center of the lamp filament is in the common focal point of the ellipse and parabola. A fine light-diffusing structure overlies the light-reflecting surface to improve the uniformity of the light field.
