Abstract (en)
A method of controlling illumination in a household appliance (40) including receiving ranging measurement data from each of a plurality of distance sensors (101, 102, 103) arranged at fixed positions relative to the appliance. The ranging measurement data indicates a distance reading taken by the respective distance sensor. The position of an object relative to the appliance can be determined from the received ranging measurement data, and at least one area (401-1, 401-2, 401-3) of the appliance can be identified based on the determined position of the object. A control signal to adjust the illumination of the identified area is then transmitted to at least one of a plurality of lighting devices (20-1, 20-2, 20-3) of the appliance.
