More Information
Summary:The device has a semiconductor chip and an optical unit (2) comprising a radiation emission surface (4) for attaching at an optoelectronic component. The emission surface has a concave curved partial region (7) and a convex curved partial region which partially surrounds the concave curved partial region in a distance to the optical axis. The optical axis proceeds through the concave curved partial region.
