  • ballast mentioned above is representative of converters, sensors, lights and other participants in a lighting system.
  • the techniques, configurations and protocols specified for the interfaces are essentially interchangeable.
  • the interfaces can either be open to the outside or hidden. A selectively openable and closable cover of the respective interfaces is of course also possible.
  • circuit board 1 was described above primarily as being arranged in the ballast, it should be understood that the circuit board 1 can alternatively or additionally also be arranged in other participants and components of a lighting system, for example the lighting system 8 .
  • circuit board 1 can also be part of a sensor or an actuator.
  • An intelligent sensor IS is described below, which preferably has circuit board 1, as described above has been described includes. Consequently, the description of the ballast V and the 1 essentially also for the intelligent sensor IS.
  • the intelligent sensor IS can be connected to the BS lighting system.
  • the intelligent sensor IS can also be connected to a higher-level bus system (eg an IPv6 bus system, overlay network, . . . ) and can have a microprocessor 2, a memory unit 3 and, in particular, application software A.
  • the intelligent sensor IS can communicate with the microprocessor 2 in a wired or wireless manner (dashed double-headed arrow).
  • the microprocessor 2 does not necessarily have to be part of the intelligent sensor IS.
  • the intelligent sensor IS can read out and store data from a number of connected sensors NIS, which have no intelligence, ie in particular no microprocessor and memory, in a wired manner via a bus line BL or wirelessly. Data that has been read out can be processed by the microprocessor 2 .
  • the lighting system BS can also have other intelligent sensors and thus connect at least two sensors to one another.
  • the bus line BL can form the signaling interface S.
  • the programming interface P and the signaling interface S can use the same hardware and only be separated in terms of software.
  • the intelligent sensor IS can also specify or adopt functions and/or limit values for the non-intelligent sensors NIS or other intelligent sensors IS.
  • the intelligent sensor IS can use one or more ballasts or converters depending on Control and/or configure collected data, eg from the non-intelligent sensors NIS and/or own data.
  • the non-intelligent NIS sensors can be designed as simple motion detectors (e.g. PIR) or light sensors (e.g. LDR).
  • the intelligent sensor IS can be a thermal imaging camera. If a detection event is recorded by a non-intelligent sensor NIS, then this can transmit information to the intelligent sensor IS about the fact that a detection event has been recorded.
  • the application software A of the intelligent sensor IS can evaluate the transmitted information in an application-specific manner and, depending on this, control at least one other subscriber T of the lighting system BS, preferably a ballast or a converter.
  • the intelligent sensor IS and/or the non-intelligent sensors NIS can also be integrated into one or more ballasts or converters.
