Claim Text:
1. An optoelectronic semiconductor component comprising: a lead frame with a plurality of lead frame parts; an optoelectronic semiconductor chip, mounted on a first one of the lead frame parts, the semiconductor chip for generating a radiation during operation; and a radiation-transmissive potting body that connects the lead frame parts together mechanically and is configured for beam-shaping of the radiation; wherein the first lead frame part comprises a reflector trough with a base surface, on which the semiconductor chip is mounted; wherein the reflector trough comprises a circumferential surface that comprises first, second and third sub-regions which, when viewed in plan view, surround the base surface and succeed one another in a direction away from the base surface; wherein in the first sub-region, which lies closest to the base surface, the circumferential surface is oriented with a tolerance of at most 10° perpendicular to the base surface; wherein the first sub-region projects beyond the semiconductor chip in a direction away from the base surface; wherein in the second sub-region, the circumferential surface has a gentler gradient than in the third sub-region; wherein the first and second sub-regions transition into one another with a bend; wherein the semiconductor component is surface-mountable; and wherein a diameter of the base surface is between 1.1 times and 1.7 times a length of a diagonal of a main radiation side of the semiconductor chip.
