1. A lighting device comprising:
a light source apparatus to emit light;
an optical apparatus that contains a lens arrangement with at least two lenses to deflect the light in accordance with a specified light distribution to provide a basic lighting function; and
a positioner to adjust a position of a first one of the lenses along an optical axis of the lens arrangement such that a deflection of the light is adjustable to different scatter widths, wherein the positioner adjusts the position of the first one of the lenses to set a basic scatter width for the basic lighting function; and
an aperture stop that is movable along the optical axis of the lens arrangement,
wherein, in a fully assembled state of the lighting device, the first one of the lenses remains permanently fixed in the position that provides the basic scatter width.
