A light module for providing polychromatic light is provided. The light module includes a wavelength conversion element, a first light source for emitting a first light beam in a first wavelength range, and at least one second light source for emitting a second light beam. The element is configured to convert primary light radiated in by the first light beam into a first conversion light and to convert primary light radiated in by the at least one second light beam into a second conversion light. At least the first conversion light and the second conversion light together form a third light beam. The module further includes a control unit configured for predefining a first luminous intensity for the first light source and/or a second luminous intensity for the at least one second light source depending on a measurement of the light color of the third light beam.
