Abstract:
1. A light source comprising: a plurality of semiconductor chips and three different electromagnetic-radiation-emitting chip types having different emission spectra, each of said semiconductor chips having a chip coupling-out area through which the electromagnetic radiation is coupled out; a plurality of primary optical elements, each of said semiconductor chips having a respective one of said primary optical elements corresponding thereto, which has a light input and a light output and reduces the divergence of at least part of the electromagnetic radiation emitted by the semiconductor chip during operation thereof; wherein the semiconductor chips with the respectively corresponding primary optical elements are arranged in at least two groups that are spatially separated from one another, such that the groups emit separate light cones during operation of the semiconductor chips; and wherein the semiconductor chips of the first chip type are arranged in a first group and the semiconductor chips of the second and third chip types are arranged in a second group, the semiconductor chips of different chip types of the second group being arranged in a manner intermixed with one another; and a secondary optical arrangement, wherein said secondary optical arrangement superposes the separate light cones to form a common light cone.
