CONTROL DEVICE, SYSTEM AND METHOD FOR PUBLIC ILLUMINATION
First Claim
1. Control unit being operatively connected to control a light source in an illumination system for an area, said area formed by at least two cells, said control unit comprising means to monitor said cell for subjects of interest, characterized by comprising means to coordinate illumination measures with at least one corresponding control unit in at least one proximate cell by two-way communication with said corresponding control unit.

Abstract
A control unit for an illumination system, the system itself and the involved method to operate the system is presented. The control unit is operatively connected a light source illuminating substantially one cell of an area comprising at least two cells. The unit comprises means to monitor the cell for effects of interest. The unit comprises means to coordinate illumination measures with at least one corresponding control unit in at least one proximate cell by communicating with this corresponding control unit, preferably using a wireless communication method. The illumination measures can comprise adjusting light characteristics variably, setting the light source in a stand-by mode and switching off the light source.

9. System for controlling illumination of an area, said area being formed by at least two cells having a light source in each cell to illuminate said cell and a control unit operatively connected to each light source characterized by
said control unit being arranged to monitor said cell for subjects of interest, two-way communication between said control units, coordination of illumination measures between proximate control units/cells to achieve an energy-efficient illumination and a safe environment.

15. Method to illuminate an area, said area formed by at least two cells, each cell being equipped with a light source and a control unit, characterized by the following steps:
-
monitoring said cell for subjects of interest, sensing said subjects of interest; sending data about said subjects of interest to at least one corresponding control unit in at least one proximate cell, receiving data from at least one corresponding control unit, adjusting illumination according to at least one of (i) said subject of interest, and (ii) said data received from at least one proximate cell. - View Dependent Claims (16, 17)
