In order to extend the life and reduce the fitting complexity involved, what is proposed is: the light-emitting unit comprises a plurality of individual identical cooling apparatus/light-emitting means modules (3), which are connected for form clusters (5), wherein each cooling apparatus/light-emitting means module (3) comprises a ceramic carrier body (1), which has, on one or more of its surfaces, sintered metallization regions (7), said metallization regions (9) forming a printed circuit board, to which one or more LEDs (2) is/are electrically conductively connected. |
