  • Patent number: 11404619
    Abstract: In one embodiment, the light-emitting diode module comprises a carrier and a plurality of light-emitting diodes. Thereby, several types of light-emitting diodes are present. The light-emitting diodes can be controlled individually or in groups electrically independently of one another. The light-emitting diodes each comprise a first and a second electrical contact. The carrier comprises several electrically conductive main layers, between each of which there is an electrically insulating intermediate layer. The contacts of the light-emitting diodes are attached to a carrier upper side on one of the first main layers. Starting from the first contacts, electrical through-connections are each connected directly to a carrier underside with a last main layer of the main layers. Starting from the second contacts, electrical through-connection each terminate at a penultimate main layer of the main layers, wherein the penultimate main layer is located inside the carrier.
