Adaptive lighting requires two elements:
- A remote control system, a connectivity system that connects various lighting points throughout an area via software.
- Cameras with data pre-processing capabilities, enabling lighting devices to communicate directly with gateways for monitoring and management.
As mentioned, there are two adjustment modes.
- TAI (Traffic Adaptive Installation) uses a traffic detection device to count the number of vehicles in each lane in real-time. With a sampling algorithm, it can increase or decrease the operational category by up to two levels.
- FAI (Full Adaptive Installation) uses a traffic and luminance sensor to detect road light levels and weather conditions.
Through the use of the TAI system, it is possible to reduce the lighting class of a specific road area if the detected traffic is less than 50% of the nominal value. In cases where there is a decrease to 75%, a further reduction of up to two classes is permitted.
Unlike the TAI, the FAI system adopts a gradual and continuous update of the lighting class between one category and another, aiming to achieve maximum energy savings. In this sense, we can say that “the lighting continuously adapts.”
The camera is the adaptive solution integrated into the control system that, in real-time and precisely, captures data to transmit to the gateway communicating with the management platform. This results in adjusting the lighting power, either increasing or decreasing, depending on the entered parameters, such as traffic flow.
Therefore, this device, through an algorithm, identifies the required lighting level for that specific vehicular and pedestrian area, while the control system communicates with all installed nodes, point by point, to use the necessary amount of energy at that particular moment.
