The socio-astronomical calculation was invented by BH Technologies to take into account the fact that the moments of ignition are more critical in winter, at times of high traffic, than in summer when the days are longer.

This patentedalgorithm, developed especially for public lighting, combines several parameters to optimize the on and off: the place, the date, the time, the angular calculation of the position of the sun and the sociological data relating to the attendance of the City.

We will turn on and off later in winter, when the night arrives during periods of high attendance and when the weather is worse, (out of school and offices, daily trips, etc.).
Conversely, when the night comes later, when everyone has returned home, the environment is more readable, and we can afford to reduce the ignition time even more.

The socio-astronomical calculation is a precise response to the specific needs of publiclighting. All Radiolite are equipped with it.

To be accurate, an astronomical calculation needs location information, (obtained by the IGN code or precise GPS coordinates), date and time to switch the lighting precisely according to the season.
If the astronomical clock is not on time, its switching will be fanciful and it will be impossible to seek a minimum ignition time without harming the safety of local residents.

All radiolite are constantly updated, either by the ALS162 transmitter (ex France Inter) or by GPS satellites. They have the same time, and therefore switch at the same time on the same site.
It then becomes possible to minimize the operating times of the lighting, to turn on at the limit of visual perception, without creating dangerous contrasts between the neighborhoods.

All non-radio-synchronized clocks installed outdoors derive strongly due to thermal variations. It is common to see drifts of 30 minutes a year!

With a completely scalable offer, BH Technologies is dedicated to evolving step by step towards the smart city. Indeed, you can start by using Radiolite clocks in autonomous mode and evolve towards the remote control of your installations thanks to LoRaWAN connectivity without adding or replacing equipment.

ü Avoid the systematic movement of technicians on site to modify a schedule or control the operation of a clock. This generates significant savings on operating costs and a reduction in CO2 emissions related to pollution from service vehicles.

ü Serenely make night cuts to achieve energy savings with the possibility of acting at any time and remotely to turn the lighting back on in the event of an incident. This makes the nightlife of the city safer.

Astrosat replaces all stand-alone photoelectric cells on the market. The supplied adapter ring allows Astrosat to be installed on existing caps without changing the wiring.

Infralux is a patented twilight contactor that measures ambient brightness by detecting infrared rays contained in sunlight. The commutations are directly generated by the disappearance or appearance of the sun on the horizon. This advantage, without equivalent, ensures very precise switches that are not sensitive to the orientation or aging of the sensor. Ideal for mountain or seaside facilities exposed to very changing weather situations.
