Video endoscope with switchable semiconductor light sources

A video endoscope comprising

• an endoscope part having at a proximal end thereof
• a central image signal conductor,
• at least one optical waveguide, and
• a light supplying part which can be coupled to said proximal end of said endoscope part, said light supplying part has
• a central image signal conductor connection at a distal end thereof, and
• a light supply arranged coaxially around said central image signal conductor connection in a coupling area of said light supplying part,
• said endoscope part and said light supplying part are rotatable with respect to one another when coupled, wherein
• said light supply has a plurality of light-emitting elements arranged around said central image signal conductor connection, each of said light-emitting elements can be supplied by means of a switchable semiconductor light source;
• and wherein
• position sensors are arranged in an area of said light-emitting elements, and
• position indicators are arranged on said endoscope part in an area of said at least one optical waveguide,
• a position of said position indicators can be detected by said position sensors when said endoscope part and said light supplying part are coupled, and wherein, based on a detection of said position indicator by a position sensor, at least these light-emitting elements lying opposite to said optical waveguide are activated.
