Abstract
Photometric calibration data for lighting devices that include a plurality of electrically powered light radiation sources are obtained by positioning a photometric sensor configured to be impinged upon by light radiation emitted by a lighting device. There is detected, via the sensor and with the device deactivated, a background lighting level signal. There are then detected, via the sensor and with the device activated, light-emission signals, which are processed on the basis of the background-lighting level signal to obtain clean emission signals. The photometric calibration data are produced starting from said clean emission signals and can be used both for (re)calibrating the emission parameters of the same lighting device with respect to which the sensor has been positioned and for modifying the light emission parameters of one or more cloned lighting devices other than the lighting device with respect to which the sensor has been positioned.
