The ASTRO astronomical clock can optimally and completely automatically solve the electricity supply program for public lighting throughout the year, thus avoiding all errors occurring with the current command systems.
At most ON points, the photocell system is used as a means of commanding the public lighting but it is gradually abandoned by users because it does not allow a rigorous control of the Start/Stop, because photocell is being affected by fog, cloud, dust, etc.
Lately, users have turned their attention to the regular programmer clock system that allows the public lighting to be switched on / off at the scheduled hours desired.
However, this command system also has the inconvenience that over a year, periodically every 10 ... 15 days, the switching program (Start/ Stop) must be manually corrected by an operator depending on the astronomical change of the sunrise and sunset hours of the sun.
This equipment performs fully automatic command of public lighting strictly at the desired hours and correction of the Start / Stop hours throughout the year, depending on the sunset and sunrise hours for the geographical coordinates of the locality, thus eliminating the periodic corrections of the program, with inevitable errors caused by the human factor.
