Abstract:
1. A medical illumination unit, which comprises: a rod-shaped or tubular body having a proximal end, a distal end, at least one distal hollow section that begins before the distal end and reaches the distal end, and a supply lead section that begins at the proximal end and reaches the distal hollow section, the supply lead section having a contact arrangement at its end facing the distal hollow section, the contact arrangement having a central contact and an edge contact in the form of a ring enclosing the central contact; an LED chip arranged in the distal hollow section of the body and being supplied with energy through the supply lead section, the LED chip being arranged on and electronically contacting the central contact and being connected to the edge contact by a bonding wire; and a luminescent converter material arranged between the LED chip and the distal end of the body or at the distal end of the body, the converter properties of the luminescent converter material in respect of the light emitted by the LED chip being selected so that the luminescent converter material converts light emitted by the LED chip into light with a desired wavelength distribution.
