Lighting device for a motor vehicle for creating a light animation

A motor vehicle, comprising;

• a lighting device which further comprises:
• a light emission device for creating the light animation, the light emission device being subdivided into a plurality of segments;
• and
• a control unit which is configured to:
• separately control each of the plurality of segments of the light emission device;
• control the plurality of segments differently at a plurality of points in time with respect to a photometric parameter relating to each of the plurality of segments in order to create and/or output the light animation;
• apply a different current or voltage to each segment of the plurality of segments such that an average of the photometric parameter of the lighting device across the plurality of segments for the light animation is within a predefined interval;
• determine a subset of the plurality of segments that forms a closed curve;
• keep constant a first corresponding luminance of the subset of the plurality of segments that are assigned to the closed curve;
• vary a second corresponding luminance of another subset of the plurality of segments that are assigned to an inner region of the closed curve for the light animation;
• and
• use a control function to control each of the plurality of segments, wherein the control function describes a luminance of each of the plurality of segments at points in time and the predefined interval of the average photometric parameter wherein the predefined interval has a lower limit and an upper limit, and wherein the control function is a random function created using a random generator.

• separately controlling each of the plurality of segments of the light emission device;
• controlling the plurality of segments differently at a plurality of points in time with respect to a photometric parameter relating to each of the plurality of segments in order to create and/or output the light animation;
• applying a different current or voltage to each segment of the plurality of segments such that an average of the photometric parameter of the lighting device across the plurality of segments for the light animation is within a predefined interval, wherein the photometric parameter is a light intensity;
• determining a subset of the plurality of segments that forms a closed curve;
• keeping constant a first corresponding luminance of the subset of the plurality of segments that are assigned to the closed curve;
• varying a second corresponding luminance of another subset of the plurality of segments that are assigned to an inner region of the closed curve for the light animation;
• and
• using a control function to control each of the plurality of segments, wherein the control function describes a luminance of each of the plurality of segments at points in time and the predefined interval of the average photometric parameter wherein the predefined interval has a lower limit and an upper limit, and wherein the control function is a random function created using a random generator.
