1. A household appliance, comprising:
an appliance housing having a door and an interior receiving space;
an illumination apparatus for illuminating said interior receiving space with a base illumination scenario upon opening said door, said base illumination scenario being independent of a brightness of ambient light in an environment;
an ambient light detection unit including a sensor housing, a brightness sensor disposed in said sensor housing, said brightness sensor detecting the brightness of the ambient light upon opening said door, and a lens focusing the ambient light incident on said sensor housing toward said brightness sensor; and
an evaluation unit for evaluating the detected brightness, generating an end illumination scenario for said receiving space based on the evaluated detected brightness and replacing the base illumination scenario with the end illumination scenario.
