Claim of US Patent No. 10,893,588

1. A method of operating a lighting device with a light-emitting component, in whichthe light-emitting component comprises a plurality of pixels configured to illuminate a plurality of zones in a field of view,
the light-emitting component comprises a processing device comprising characterization data of the light-emitting component, and
the pixels of the light-emitting component are operated as a function of the characterization data, whereinto determine characterization data prior to intended operation of the lighting device an intensity and/or a color location of the emitted light of a pixel or of each pixel is measured as a function of an operating current,a set point comprising a brightness set point and a color location set point, is assigned to a zone,
the zone has an actual value comprising an actual brightness value and an actual color location, and
the actual value of the zone is approximated to the set point in several steps.
