A semiconductor radiation source, having at least two light sources which are fixed on a common base body and so light can be emitted gently over a total emission spectrum, the first light source having a short-wave, in particular from 400 to 430 nm emission spectrum, and the second light source having a longer-wave, in particular from approximately 450 to 480 nm emission spectrum. The first light source (16) is arranged in an optical axis (22) and the second light source (18) has at least two chips (24, 26, 28, 30) which are arranged in particular symmetrically with respect to one another and with respect to the optical axis (22) and in a manner surrounding the optical axis (22).
