A method for transmitting control commands in a system () of units (L-L) in a distributed arrangement, for example in a lighting system having luminaires in a distributed arrangement, involves at least some of the units (L-L) sending a received control command again in order to ensure that the control command is forwarded to all units (L-L). The control command contains a piece of information regarding an already past command transmission time, wherein each unit (L-L) takes the command transmission time that a received command contains as a basis for determining an individual waiting time (TTL), after the expiry of which the command is executed by the unit (L-L).

Method and system for transmitting control commands for units in a distributed arrangement

The invention relates to a sensor assembly () for capturing spatially resolved photometric data comprising a sensor unit (), a controllable shutter assembly (), which is arranged in front of the sensor unit () and by means of which an incidence of light on the sensor unit () can be controlled in dependence on direction, and an evaluating unit () for evaluating the information output by the sensor unit () and calculating spatially resolved brightness information, wherein the sensor unit () has at least two sensor segments (), with which different combinations of color and polarization filters () or spectrometers are associated, and wherein the evaluating unit () is designed to supplement the brightness information with additional photometric data on the basis of the signals output by the various sensor segments ().
