Abstract: An illumination device includes a primary light unit for the emission of primary light, a phosphor element for the conversion of an excitation light part of the primary light and as a result the emission of conversion light, and a coupling element, to supply the excitation light part of the primary light to the phosphor element. The element has a first conversion region, which is configured to emit a first conversion light, and a second conversion region, which is configured to emit a second conversion light, which differs in its spectral properties from the first conversion light. The primary light unit, the element, and the coupling element are arranged such that in operation, the excitation light part is supplied to the phosphor element via the coupling element, wherein simultaneously a useful light part of the primary light is also supplied, guided via the coupling element, conversion-free to an illumination application.

Abstract: A light module for providing light includes an excitation radiation source which is adapted to emit excitation radiation, at least one first phosphor which is adapted to at least partially convert the incident excitation radiation into conversion light and to generate with this conversion light a first light path, and a phosphor apparatus having a segmentation which has at least two different types of segments, with the segments of the first type comprising the first phosphor. The light module is designed for a periodic movement between an excitation beam that is coming from the excitation radiation source and is incident on the phosphor apparatus and the segmentation, in which there is at least one phase per period in which more than two segments are at least partially irradiated simultaneously by the excitation radiation.
