Abstract
In at least one embodiment, an optoelectronic lighting module includes a circuit board, which an opening passes right through. The circuit board includes fastening devices for mechanically fastening the lighting module to an external heat sink. A carrier of the lighting module is mounted in the opening. At least one optoelectronic semiconductor chip is located on a carrier top and is connected electrically to the circuit board via the carrier. The circuit board is moreover connected firmly mechanically with the carrier. The circuit board is additionally designed to exert a mechanical force on the carrier and to press the carrier against the external heat sink. The carrier is designed to rest with a carrier bottom flat against the external heat sink.
