Small Demonstration Site: First Adaptive Lighting Test

112 luminaires, at end of March 2018, were equipped with Diademe technology for smart lighting in ROMA, EUR district. These devices are collecting data about luminance, traffic flow, air quality, noise level, temperature, pressure and pole inclination, providing adaptive lighting to the streets involved in the project.

A 15 days Testing, along Via dell’Aeronautica, was performed to evaluate how adaptive lighting system performs in urban environment and particularly to demonstrate that adaptive system is able to regulate lighting level on the base of real time traffic detection and luminance level.

Adaptive lighting data were compared with two different conditions: full light and pre-programmed cycle regulation. Full light is the standard regulation for ROMA EUR lighting fixture. Furthermore, street lights were regulated measuring real time luminance and traffic flow, providing however correct luminance level as prescribed by UNI 11248.

The conclusion of the Test was very encouraging. Energy saving through the Adaptive Lighting System, if compared with pre-regulated cycle, was higher than project target: 53% instead of 30%, while the performance was 66% if compared with full light driving, the current standard for ROMA EUR lighting plants.

In January 2019 other about 900 lighting points will be equipped with the Diademe System, as foreseen by the project targets.
