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 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%.
