Abstract: 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.

Abstract: Various embodiments relate to a lighting device with an optoelectronic light source, an optical body downstream thereof for distributing the light, and a diffuser downstream of the latter, onto the light entry surface of which the light emitted by the optical body falls and the light exit surface of which represents a light emission surface of the lighting device. To homogenize the luminous intensity on the light exit surface, in addition to distributing the light with the optical body, the diffuser is not provided to be uniformly scattering to such an extent that light falling thereon in a central region is scattered more intensely than light falling thereon in an edge region.
