autonomous lamp post head
The Autocontrol system makes it so that autonomous
street lights are able to automatically adjust the
luminous flow based on the selected programming
depending on the technical lighting needs. The system
works in combination with a timer or a twilight switch
upstream of the system which determines the daily
hours of operation.
Generally, the operating time is divided into 5 time
slots, proportional in percentage to the “N” duration of
the night. This time is stored by the power supply and
used to determine the hours of operation in the various
time slots of the following day.
Examples of operation
Dimming varies according to the season of the year
and latitude of the location. Below are two examples
of operation in periods of the year that differ in number
of night hours. With the Autocontrol system, a daily
energy savings can be achieved that varies between
20% and 25%.
