Abstract
A laterally emitting radiation-generating component comprising a radiation source, the optical axis of which runs perpendicular to a mounting area of the component, and comprising an optical device arranged downstream of the radiation source. The optical device includes a reflective surface shaped like a V in cross section and a refractive surface that is shaped convexly as seen externally and is arranged between the reflective surface and a bottom area facing the radiation source. The bottom area is arranged and formed in such a way that through it electromagnetic radiation from the radiation source couples into the optical device. The reflective surface is arranged and formed in such a way that a central first portion of the coupled-in radiation is deflected toward the refractive surface by the reflective surface. The refractive surface is arranged and formed in such a way that both a radiation coming from the reflective surface and a radiation coming directly from the radiation source are coupled out through it with simultaneous beam focusing laterally with respect to the optical axis of the radiation source.
