a second upper section of the upper side of the first lead frame section is not covered by the plastic material in the second recess,
the first recess and the second recess are separated from one another by a section of the plastic material,
an optoelectronic semicondustor chip is arranged in the first recess, and
no optoelectronic semicondustor chip and no bond wire are arranged in the second recess.
2. The optoelectronic component as claimed in claim 1 ,
wherein a first lower section of a lower side of the first lead frame section is not covered by the plastic material, and
the first lower section overlaps the first upper section in a projection perpendicular to the first lead frame section.
3. The optoelectronic component as claimed in claim 1 ,
wherein a second lower section of a lower side of the first lead frame section is not covered by the plastic material, and
the second lower section overlaps the second upper section in a projection perpendicular to the first lead frame section.
4. The optoelectronic component as claimed in claim 1 , further comprising a second lead frame section at least partially embedded in the plastic material,
