1. A light source comprising as components which superimpose one another in this sequence:
at least one first light-emitting semiconductor component;
at least one second light-emitting semiconductor component;
a plurality of carrier elements, wherein a first carrier element of the plurality of carrier elements comprises a first carrier surface which faces the at least one first light-emitting semiconductor component and a first cooling surface, and a second carrier element of the plurality of carrier elements comprises a second carrier surface which faces the at least one second light-emitting semiconductor component; and
a distributor element comprising a first cavity to provide inflow of a fluid and a further cavity to provide return flow of the fluid,
wherein:
the first cavity and the further cavity are fluidically connected to one another by a first fluid path,
the first carrier surface and the first cooling surface are mutually opposite external surfaces of the first carrier element, and
the first carrier element has a cooling structure with a surface and the first cooling surface is at least in part the surface of the cooling structure of the first carrier element, and
the cooling structure comprises cooling ribs,
wherein the distributor element has an external surface that faces the first cooling surface, and the first fluid path is at least in part additionally delimited by the external surface of the distributor element that faces the first cooling surface.
