Abstract:
In order to control the luminosity in a room (1) lighted with several light sources (2a..., 3a...) or several groups of light sources, a system is used with which the ratio between the light intensities of the individual light sources or groups of light sources can be adjusted or modified, and with which the total luminosity in the room (1) can be adjusted or modified while the ratio between the light intensities of the individual light sources or groups of light sources is kept constant. In particular for this purpose, a control device (7) is integrated in the system and connected to all operating devices (4a..., 5a...) of the various light sources (2a..., 3a...) to control the power consumption of the individual light sources (2a..., 3a...).
