Abstract

An illumination unit for illuminating an area of operation during open surgery. The illumination unit including: a body; a fiber bundle configured to guide light towards a distal end of the body, and a reflector body arranged at the distal end of the body. Where at least a part of the fiber bundle is guided inside the body along a longitudinal direction, the fiber bundle is split up into a plurality of optical fibers which form a fiber layer on an inner surface of the body, end faces of the plurality of optical fibers are arranged at the distal end of the body, the reflector body encloses the end faces of the plurality of optical fibers in a radial direction and extends distally beyond the distal end of the body in the longitudinal direction, and an inner surface of the reflector body is a reflective surface.
