PROBLEM TO BE SOLVED: To provide a device, wherein the coupling of LED light into an optical waveguide is optimized with regard to technical complexity, efficiency and economic costs, wherein the light from different types of LED light sources can be used in an identical manner, and whereby undesirable optical effects during the transmission of light are avoided. SOLUTION: A fiber-optic device includes: at least one LED light source having at least one light-emitting semiconductor surface; a fiber-optic optical waveguide, having a multiplicity of individual optical fibers combined at one end to form a light-receiving entrance surface; and a lens arrangement, having optical lenses assigned directly with one another, for imaging the light from the LED light source onto the entrance surface. The lens arrangement includes at least two aspherical lenses, with at least one input lens and one output lens, having a larger diameter with respective thereto, and an input lens is assigned to each light-emitting semiconductor surface.
