Patent ID: 8167470

Claim:
An illumination device for generating light and supplying said light to an observation device used in endoscopy or microscopy, comprising: a light source having at least one LED, one or more optical waveguides having a proximal end and a distal end, said proximal end being arranged on a side of said light source which faces said optical waveguide, a cooling device to dissipate heat generated by said light source, wherein said cooling device has at least one first cooling element for dissipating heat generated by said light source, said at least one first cooling element being arranged on a side of said light source which faces away from said proximal end of said optical waveguide, and a second cooling element for dissipating heat generated by said light source, said second cooling element being arranged on a side of said light source which faces said proximal end of said optical waveguide, said one or more optical waveguides passing through said second cooling element.
