Illumination device for variable illumination

A motor vehicle headlamp having an illumination device comprising,

• 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 assigned to the luminescent element for and respectively directing illumination light ray bundles striking the optics on a luminescent material side thereof from different positions of the illumination light emission surface, into a different spatial direction of a propagation on an illumination side opposite to the luminescent material side,
• wherein 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, wherein the optics convert the angular distribution on the illumination side into a position distribution on the illumination light emission surface to permit adjustable excitation of different positions of the luminescent element.

A method for using an illumination device for a motor vehicle headlamp comprising,

• emitting pump radiation by a pump radiation source of a pump radiation unit,
• exciting, by the pump radiation, an illumination light emission surface of a luminescent element,
• converting, at least partially, the pump radiation into illumination light by said excitation of the luminescent element,
• assigning optics to the luminescent element, and
• directing into different spatial directions of a propagation on an illumination side of the optics, respectively, illumination light ray bundles striking the optics, from different positions of the illumination light emission surface on a luminescent material side of the optics opposite the illumination side,
• wherein 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, wherein the optics convert the angular distribution on the illumination side into a position distribution on the illumination light emission surface to permit adjustable excitation of different positions of the luminescent element.
