Abstract
A method of self-calibrating a lighting device, comprising: —monitoring a calibration area, which encompasses at least a part of an area being illuminable by the lighting device; and—calibrating the light output settings of the lighting device. The monitoring operation includes repeating: —detecting any relevant change, out of a set of relevant changes comprising at least a light intensity change, in the calibration area during a monitoring time, while keeping the light output of the lighting device constant; and—determining an amount of change within the monitoring time; until the amount of change is below a limit value. Thereby the lighting device does not perform the calibration until it has detected a period of no or small changes.
