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.
