Abstract

Various embodiments relate to an irradiation device including a pump radiation source for emitting pump radiation, a conversion element for converting the pump radiation into conversion radiation of longer wavelength, and a reflection surface, which is reflective to the conversion radiation and on which backscattered conversion radiation emitted at a backscatter emission surface and thus counter to a useful direction is incident and is reflected therefrom back to the conversion element; said reflection surface is concavely curved relative to the conversion element in such a way that at least the backscattered conversion radiation emitted divergently from a surface centroid of the backscatter emission surface is incident on the reflection surface at an angle of incidence of at most 20° in terms of absolute value.
