Abstract:
1. An optoelectronic semiconductor component for a lighting device comprising: a carrier, at least one optoelectronic semiconductor chip mounted on the carrier and which comprises a radiation passage face remote from the cartier, by which a plane is defined, and a lens comprising: 1) a radiation exit face, which, relative to a height above the plane, exhibits a minimum, in particular in a central region, and at least two Local maxima, and 2) at least two connecting embankments which each extend from one of the maxima to another of the maxima, and each connecting embankment comprises a saddle point higher than the minimum and lower than the maxima adjoining the connecting embankment, wherein height h of the radiation exit face of the lens may be approximated, relative to the plane, by a polynomial of the form with a tolerance of at most 0.05 times the respective local, actual height h(x,y) of the radiation exit face, wherein at least a.sub.0, a.sub.3, a.sub.5 and a.sub.7 are other than zero.
