Abstract
The invention relates to an LED-module (1) for emitting mixed light, preferably white light, comprising a light field (2′″;2″″) which is divided into several flat sectors for dispensing different light spectra. The flat sectors of the light field (2′″;2″″) are embodied as sectors of a circle (3c′″,3d′″;3c″″,3d″″) and sectors of a circular ring (3a′″,3′″;3a″″,3b″″).
