Patent ID: 7837371

Claim:
A light source comprising: a plurality of semiconductor chips and at least two 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 a secondary optical arrangement, wherein said secondary optical arrangement superposes the separate light cones of the groups to form a common light cone, and wherein the light input has a light input area or a light input opening, which has a size that is less than or equal to two times the chip coupling-out area.
