Abstract

An optoelectronic semiconductor component includes a lead frame with two lead frame parts and an optoelectronic semiconductor chip. The semiconductor chip is fitted to a first of the lead frame parts. A radiation-transmissive potting body of the semiconductor component mechanically connects the lead frame parts to one another. The potting body is set up for beam shaping. The first lead frame part has a reflector trough with a base surface on which the semiconductor chip is mounted. The reflector trough has a lateral surface with three sections. When seen in a plan view of the base surface, the sections revolve around the base surface and follow one another in a direction away from the base surface. In the first section, closest to the base surface, the lateral surface is oriented perpendicular to the base surface.
