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.

Abstract: A lighting device includes a light source, a reflector having an ellipsoidal reflection surface, an aspherical lens, and an exit pupil. The source is arranged at a first focal point of the reflection surface and a part of the emitted light is reflected from the reflection surface in the direction of a second focal point. The pupil is arranged offset with respect to the second focal point. The lens is arranged between the reflection surface and the pupil in a beam path with the reflected light and is shaped such that a first part of the reflected light passes through the lens with an aperture angle altered by not more than 5° in a central region and passes through the pupil and a second part of the reflected light penetrates through the lens in an outer region and is deflected by the lens and is consequently guided through the pupil.
