Lighting device with a system for regulating brightness according to the luminosity of the lighting field and corresponding use

摘要

The device (1) has a light source (5) for lighting an illumination field (2). A regulating device receives an actual luminance signal representing actual luminance (11) of a lighting field. The regulating device controls the luminance from a light source as a function of the actual luminance signal and a luminance set point signal. A determining device determines the actual luminance of the lighting field to create and transmit the actual luminance signal to the regulating device from the light source.
