Abstract

A light-emitting diode module has a first component and a second component, wherein the module exhibits a first operating mode and a second operating mode. The first component exhibits a first luminous flux. The second component exhibits a second luminous flux. In the first operating mode, the ratio of the first and second luminous fluxes is set such that the module emits mixed radiation with a color rendering index of 80 to 97. In the second operating mode, the ratio of the first and second luminous fluxes is set such that the module emits mixed radiation with a color rendering index of 55 to 70.
