Method for operating a circuit arrangement having an open-loop and/or closed-loop controller for an illumination field

A method for operating a circuit arrangement, the method comprising:

• providing an illumination field that comprises at least one first module and one second module, which each comprise at least one light source;
• providing an open-loop and/or closed-loop controller for the illumination field;
• controlling each light source by the open-loop and/or closed-loop controller such that a brightness of each light source is set based on a desired luminous intensity distribution of the individual modules or a desired overall luminous intensity distribution;
• and
• implementing continuously a transition between the desired luminous intensity distribution of the individual modules and a desired overall luminous intensity distribution,
• wherein the transition between the desired luminous intensity distribution of the individual modules and the desired overall luminous intensity distribution takes place based on at least one measured parameter, and
• wherein the luminous intensity distributions are determined using the following formula, wherein the brightness for each light source is determined from the calculated luminous intensity distributions:
