Abstract
An illuminating device includes a pump radiation source for emitting pump radiation as a beam bundle, a phosphor element for converting the pump radiation into conversion light, and a lens system between the pump radiation source and the phosphor element, which is penetrated by the pump beam bundle, wherein the lens system has a focus and the phosphor element is arranged at the focus, and wherein furthermore a lens of the lens system has a scattering means which scattering means the pump beam bundle penetrates and is widened at the same time, so that the pump beam bundle is incident on the phosphor element in a manner widened around a focus point.
