Abstract:
An illumination device for variable illumination in different spatial directions is provided. The illumination device includes a pump radiation unit, which has a pump radiation source for emitting pump radiation, a luminescent element for at least partial conversion of the pump radiation into illumination light, which is emitted in response to excitation with the pump radiation on an illumination light emission surface of the luminescent element, and optics which are assigned to the luminescent element and respectively direct illumination light ray bundles, which come from different positions of the illumination light emission surface and strike the optics on a luminescent material side, into a different spatial direction of the propagation on an illumination side opposite to the luminescent material side, The pump radiation unit is configured to respectively emit a pump ray bundle adjustably in different spatial directions, which pump ray bundles are coupled in on the illumination side.
