AUTOMATED ROAD LIGHTING CONTROL SYSTEM Russian patent published in 2012 - IPC F21S9/00 

FIELD: electricity.

SUBSTANCE: automated road lighting control system is comprised of a luminance sensor, three phase voltage switches, four video cameras to be installed in pairs on the utmost supports of the illuminated area, movements video recorder, three timers, fog detector and ice detector. At the same time, the first phase of three-phase network is connected to luminance sensor input with its output being coupled with the first switch input. The first switch output has connections with the first inputs of each N-lamp based on light diode. The inputs of video cameras power supply, movement video recorders power supply, timers, switches and fog and ice detector power supply inputs are coupled respectively with the third, first, fifth and fourth input of video detector. The output of video detector is connected with the first timer input having its output connected with the second timer input. The output of second timer is linked with the second switch input, and the second timer output is connected with the second switch input, while the second output of second switch is coupled with the third timer input having its output connected with the third switch input. The third inputs of the second and third switches are connected respectively with the second and third phases feeding a section of network. The first output of the second switch and the third switch output are connected with the second and third inputs of each N-lamps and fog detector output is connected with the fourth inputs, ice detector output is linked with fifth inputs of the second and third switches.

EFFECT: energy saving, uniform lighting when automated system is switched over to energy saving or stand-by night mode of operation.
