The functions are grouped into local and central functions depending on
whether the function acts on one or multiple lamps in a room, or on an entire
group of lamps, e.g., on all lamps of a renter.
Grouping by local and central functions for the examples from
the figure above
Local manual operation Fir alarm Scheduler program
Central function n/a Fire alarm reception
Commanding of On-command
Commanding of On/Off command
in dependence of time
Local function Commanding of manual brightness
Adapting lighting
Switching on lighting Switch on/off lighting
The control concept is based on the following:
● Grouping into autonomous functions determining a command for lighting
● Priority assignment to individual functions
● Evaluation of all functions and decision on the state of lighting based on
priorities
Autonomous functions to control lighting
Priorities depend on plant requirements. The table shows the typical priorities
in ascending format.
Function Description
Automatic control Automatic switch-on/switch-off based on brightness, constant lighting control.
In simply terms, this function achieves optimum lighting conditions automatically in
occupied rooms, and switches off lighting when rooms are unoccupied.
Manual operation (room, central) Manual operation allows users to themselves determine brightness via buttons. If
manual operation overrides a lower-priority function, a scheduler program or local
presence information will reactivate the function.
Presence-based influence (room) Automatic switch-on when dark upon entering a room, and automatic switch-off when
leaving a room. The presence-based function generally acts on the same priority as
manual operation.
