Abstract:
1. Method for controlling a lighting system, said lighting system comprising a plurality of luminaires, a plurality of sensors, a central control unit, and a network establishing a communication between the luminaires, the sensors and the central control unit, wherein in a standard operation mode, the luminaires are controlled by the central control unit on the basis of sensor data transmitted from the sensors to the central control unit and according to a standard control algorithm corresponding to a set of standard operation commands, wherein in case of failure of operation of the central control unit or networking interruption between the central control unit and the luminaires or sensors, the lighting system switches into a fallback mode wherein each luminaire is controlled by a fallback control unit allocated in the luminaire or in a sensor associated to the luminaire, wherein in the case of said fallback control unit being allocated in the luminaire, the luminaire is controlled in the fallback mode on the basis of sensor data received from a sensor whose network address is stored in the fallback control unit of said luminaire, and wherein in the case of said fallback control unit being allocated in a sensor associated to a luminaire to be controlled by this sensor, this luminaire is controlled in the fallback mode on the basis of sensor data provided by this sensor, the network address of the luminaire to be controlled being stored in the fallback control unit of the sensor, and wherein in said fallback mode, said fallback control unit operates according to a set of fallback operation commands representing a subset of said set of standard operation commands.
