摘要

An illumination system for generating light and for coupling of the light in a proximal end (22) of a light-guide cable (24) of an observation device for endoscopy or microscopy, with an at least one led (72) having a light source (14), with an optical light guide element (16) between the light source (14) and the proximal end (22) of the light-guide cable (24) for introducing the of the light source (14) emitted light in the proximal end (22) of the light-guide cable (24), wherein a first end portion (76) of the optical light guide element (16) on one of the light source (14) side facing a smaller cross-sectional area (78) as a second end portion (82) of the optical light guide element (16) on a the proximal end (22) of the light-guide cable (24) facing side, and with a cooling device (18), the at least one heat sink (20), and the with the light source (14) is thermally conductively connected, in order from the light source (14) from the heat produced in the illumination system (10), characterized in that the heat sink (20) to completely..
