providing, by the sensor device, environmental data that at least partially images the illuminated area or the environment volume,
determining a position of the object with respect to the infrastructure luminaire or determining a property of the shadow cast by the object, the object being imaged by the environmental data; and
the evaluating the fulfillment of the control condition or a light intensity of the light radiated into the partial lighting volume is further based on the position of the object or the property of the shadow cast by the object.
5 . The method according to claim 1 , further comprising:
determining, based on digital map data, whether the infrastructure luminaire is present.
6 . The method according to claim 4 , wherein the illuminated area or an environment section that is situated below the illuminated area or the environment volume, or below the infrastructure luminaire is classified, the method further comprising:
the evaluating the fulfillment of the control condition or the light intensity of the light radiated into the partial lighting volume is further based on whether the illuminated area or the environment section is classified as a walking path or a bicycle path.
