A light emitting assembly includes a first light emitting component, a second light emitting component, and a third light emitting component. The components are arranged such that a first light, a second light and a third light mix to form a mixed light. The assembly includes a control device, which has a first control channel and a second control channel operating the three components and configured such that in a first operating range the first component is driven via the first channel and the second and third components are driven jointly via the second channel. In the first operating range the mixed light is continuously adjustable from the first color to a fourth color, and in a second operating range the second component is driven via the second channel and the first and third components are driven jointly via the first channel.
