If the lighting level can be regulated via the luminaire control system depending on traffic, energy consumption is reduced considerably because the candelabra only lights up when someone is travelling on the road. If 100% of the luminaire output is required for standard-compliant lighting when there is heavy traffic, around 20% is sufficient for safe orientation at night when there is very little or no traffic, for example. This means an additional savings potential of up to 80% of energy consumption. The retrofitting of motion detectors in existing candelabra therefore enables fast and uncomplicated traffic-dependent lighting control.
If this new approach to lighting control is to be used, all road users must be recognised absolutely safely and reliably. The motion detectors must be able to reliably detect all movements at all times - regardless of the ambient temperature.
In winter, a warmly dressed cyclist cannot be correctly recognised by the thermal imaging camera. In warm areas, a person with an ambient temperature of 30° in summer cannot always be reliably detected either. Thermal images from electric cars are also becoming an increasingly big challenge for conventional motion detectors.
This is where radar technology comes into play. It enables the desired additional energy savings without compromising on safety.
Similar to the frequently used speed radar controls, these apply the principle of the well-known Doppler effect and are therefore completely independent of ambient temperatures. Radar sensors provide reliable and uncompromising detection of the movements of people, cyclists and all other road users.
The new radar motion detector from BURRI is compact, safe and suitable for the latest ZHAGA D4i luminaire standard. When integrated into conventional street lights, the investment can be amortised after around 16 months through energy savings. The full functionality of the street lighting is retained and all road users are always travelling safely in the right light.
