Abstract:
Various embodiments may relate to a lighting apparatus for a headlight for generating a light emission pattern in a far field, including at least one light source for emitting primary light onto an illumination surface, at least two different phosphor surfaces which are introducible into the illumination surface, at least partly alternately by at least one translational movement, and a control device for positioning the phosphor surfaces in relation to the illumination surface. A respectively associated light emission pattern is generatable in a predetermined position of the phosphor surfaces. The control device is configured, for the purpose of setting a specific light emission pattern, to move at least one phosphor surface provided for this purpose into the illumination surface by at least one translational movement.
