  • Intelligent lighting device with multiple luminaires, in particular free-standing luminaires or desk-mounted luminaires and a method for operating a lighting device of this type
    Patent number: 9265131
    Abstract: The invention relates to an intelligent lighting device with multiple luminaires, which are at least partially coupled to each other with a wireless communication device. For this purpose, the luminaires preferably have communication modules with transmitter/receiver devices, via which the luminaires can communicate with each other. It is thereby provided that in accordance with the current operating mode of one of the luminaires at least one of the other luminaires can adopt a different predefined operating mode. Said luminaire can, for example upon the switching on of a luminaire or when one of the luminaires detects a person by means of a sensor device in the area of the luminaire, go into a working level with a predefined light intensity and the other luminaires located in the vicinity of said one luminaire go into a background illumination, i.e. in an illumination with a lower illumination level (background level).
