SWITCH ON AND SWITCH OFF AT THE RIGHT MOMENT

Street lighting astronomical clock : light up the city as late as possible  in order to use natural lighting at maximum, turn off before the un rises, take into account the weather, synchronize commutations of many action points to save up to 400 hours of ignition per year

OF PUBLIC LIGHTING

SWITCH ON AT THE RIGHT MOMENT

Switching on and off at the right moment means taking full advantage of natural light in order to save energy. It also considers the needs of daily migrations in winter, for example, at the very beginning or at the end of the day, when natural lighting is at tis lowest level.

FOLLOWS TRENDS OF THE SEASONS’ 

A patented astronomical calculation was invented by BH Technologies that account for the fact that lighting times are more critical in winter at peak hours than in summer when days are longer. The astronomical clock follows the rhythm of the seasons to propose adapted ignition times for every day of the year

THE IMPORTANCE OF SYNCHRONISATION

To be precise, an astronomical calculation needs location, date and time information to switch lighting effectively according to the season. If the astronomical clock correctly callibrated, its actions will be irregular and it will be impossible to calculate the minimum duration of lighting without influencing the safety of the citizens
