Abstract

The invention provides a light control system for a lighting network, including a plurality of light units wherein at least one light unit includes at least one sensor type, a distributed/centralized controller/central management system in communication with one or more of the light units, said controller/central management system sends control commands to one or more of said light units, in response to received light unit status/sensor information from one or more of said light units and/or status information from a connected device, and implements a lighting strategy relating to the characteristics of the plurality of light units, wherein the one or more neighboring light units' sensor type's detection threshold are adjusted using a predetermined strategy based on the new lighting strategy of the at least one light unit or the status information from the connected device.

First claim

1 . A lighting control system comprising:
at least one light unit 106 including at least one sensor 110 ; and a centralized or distributed controller 105 to control the at least one light unit's 106 lighting strategy; a connected device 114 in communication with the controller 105 ; wherein the controller 105 receives status information from the connected device 114 , wherein the status information includes an indication of an expected flux of objects directed toward the at least one light unit 106 , and adjusts the at least one light unit's 110 lighting strategy, including a detection threshold of the sensor 110 , using the status information.

2 . The lighting control system of claim 1 , wherein the controller 105 is a central management system (CMS) 102 or integrated in light unit 106 .

3 . The lighting control system of claim 1 , wherein the controller 105 adjusts the at least one light unit's 110 lighting strategy by increasing or decreasing the detection threshold of the sensor 110 .

4 . (canceled)

5 . (canceled)

6 . (canceled)

7 . (canceled)

8 . The lighting control system of claim 1 , wherein the sensor 110 is a camera and the detection threshold is adjusted only for a selected area or region in an imaging area of the camera in relation to the indication of expected flux of objects.

9 . A method of light management for a lighting system, the lighting system having at least one light unit 106 having at least one sensor 110 , a connected device 114 and a controller 105 to control the at least one light unit's 106 lighting strategy the method comprising the steps of:
receiving, in the controller 105 , status information from the connected device 114 , wherein the status information includes an indication of an expected flux of objects directed toward the at least one light unit 106 ;
and
adjusting the at least one light unit's 106 lighting strategy, including a detection threshold of the sensor 110 , using the status information.

10 . (canceled)

11 . The method of claim 9 , wherein the step of adjusting includes increasing or decreasing the detection threshold of the sensor 110 .

12 . (canceled)
