18. A method for illuminating a manipulation region of an endoscope, exoscope or microscope, in which light is transmitted by means of an optical fibre bundle from a proximal end, which has a contiguous bundle, to a distal end, which has a plurality of partial bundles, the plurality of partial bundles each separated from one another and having a plurality of optical fibres,

wherein light is coupled into the one proximal end of the optical fibre bundle by means of a light source comprising a multiplicity of individual-light sources which are arranged in an array-shaped manner and which are individually actuatable, and

wherein the individually actuatable individual-light sources of the light source are actuated with the aid of a control unit using an assignment function which represents the assignment of a proximal fibre end of the optical fibre bundle to a partial bundle.

19. The method for illuminating a manipulation region of an endoscope, exoscope or microscope as claimed in claim 18 , wherein the identity of the light source and/or the position in relation to the proximal end of the optical fibre bundle is logged and an assignment function for actuating the individually actuatable individual-light sources of the light source is selected.
