Abstract
A medical illumination unit () has an LED chip () and a rod-shaped body () with a proximal end () and a distal end (). A distal hollow section () begins before the distal end () and reaches the distal end (), and a supply lead section () begins at the proximal end () and reaches the distal hollow section (). The LED chip () is in the distal hollow section of the rod-shaped body () and is supplied with energy through the supply lead (). A luminescent converter is between the LED chip () and the distal end () of the rod-shaped or tubular body or at the distal end of the rod-shaped body (), the converter properties of which are selected to convert light emitted by the LED chip () into light with a desired wavelength distribution.
