Abstract
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 configuration having optical lenses associated directly with one another, for imaging the light from the LED light source onto the entrance surface. In order to optimize the coupling of LED light into an optical waveguide with regard to technical complexity, efficiency and economic costs, to make the light from different types of LED light sources usable in an identical manner and to avoid undesirable optical effects during the transmission of light, the lens configuration includes at least two aspherical lenses, with at least one input lens and one output lens having an increased diameter relative thereto, and an input lens is associated with each light-emitting semiconductor surface.
