Age-compensated driving of light-emitting diodes of a lighting strip of a medical device

An operating method for a medical device including a lighting strip having a plurality of individually drivable light-emitting diodes and a controller for the light-emitting diodes, the operating method comprising:

• dynamically receiving, at the controller via an interface, a request for an illumination state, which includes a partial illumination state for each of the light-emitting diodes;
• individually determining, by the controller, respective drive levels for the light-emitting diodes such that an actual illumination state of a respective light-emitting diode corresponds to a respective partial illumination state;
• and
• driving, by the controller, the light-emitting diodes in accordance with the respective drive levels determined, wherein
• in determining the respective drive levels, the controller takes into account aging states of the light-emitting diodes.
