FIELD: physics.
SUBSTANCE: in the control device, system and method for public illumination, the control unit is operatively connected a light source illuminating substantially one section of an area comprising at least two sections. The control unit has apparatus to monitor the section for effects of interest. The control unit has apparatus for coordinating illumination activities with at least one corresponding control unit in at least one proximate section by communicating with this corresponding control unit, preferably using a wireless communication method. The illumination activities can comprise adjusting light characteristics variably, setting the light source in a stand-by mode and switching off the light source.
EFFECT: power saving and high safety.
