Device and method for producing an output light emission, and headlight

A device for generating an output light emission, the device comprising:

• a light source for emitting light;
• a first polarizing beam splitter element arranged such that at least one part of the emitted light impinges thereon, whereby a first reflected light beam of a first polarization state and a second transmitted light beam of a second polarization state are produced;
• first and second projection optical units;
• a control unit;
• and
• a first liquid crystal element having at least two states which are addressable by the control unit,
• wherein the first liquid crystal element at least partly reflects the first light beam, wherein the first polarization state of the first light beam is alterable based on the state of the first liquid crystal element,
• wherein the first polarizing beam splitter element is furthermore arranged such that the first reflected light beam impinges thereon after reflection at the first liquid crystal element, and
• wherein the first reflected light beam is at least partly coupled out by the first projection optical unit to generate the output light emission, and the second transmitted light beam is at least partly coupled out by the second projection optical unit to generate the output light emission, and
• wherein the first reflected light beam is only coupled out by the first projection optical unit and the second transmitted light beam is only coupled out by the second projection optical unit.
