Rooms are lit up differently by the incidental daylight and the artificial light of the lamps. Not all the surfaces in the rooms, e.g. walls, floor, and

furniture, reflect the light that falls on them in the same manner. Accordingly, even though there is an exactly calibrated constant light control in daily

operation, deviations to the set target value may occur. These deviations may be up to +/- 100 lx, should the current ambient conditions in the room,

and accordingly the reflection properties of the surfaces (paper, people, reorganized or new furniture), differ significantly from the original ambient

conditions at the time of calibration. Deviations may also occur if the light sensor is influenced by direct or reflected light falling on it, which is not

influenced or only slightly influenced by the surfaces in the detection range of the light sensor.
