Abstract

An optoelectronic component comprises: at least one semiconductor chip suitable for generating electromagnetic radiation, a beam shaping element (1), through which at least part of the electromagnetic radiation emitted by the semiconductor chip during operation passes and which has an optical axis (2), and which has an outer contour (5) with respect to a coordinate system (3, 4) perpendicular to the optical axis (2), wherein the contour (5) constitutes a curve (n) that is mirror-symmetrical with respect to both central axes (a1, a2) of an ellipse (e) inscribed by the contour, wherein the following succeed one another in each of the four identical sections between the respective central axes (a1, a2): an ellipse segment (b1), a linear part (c1) a second ellipse segment (d), a further linear part (c2) and a third ellipse segment (b2).
