“Wireless smart lighting system was selected as most the preferred solution. As an all-round solution, it improves illumination and safety, reduces cost and cuts CO2 emissions. Due to the system’s openness and flexibility, it also offers a foundation to host innovative systems that would help us become a smart city,” explains Mr. Pflug. “Individual light management and control provide unprecedented flexibility”, adds Mr. Wiesemann.
25.000 streetlights in Dortmund (8th largest city in Germany, Ruhr Metropolis) are being converted from traditional lights to state-of-the-art LED streetlights, which also include intelligent lighting controls. Project partners include Trilux for LED streetlights, DEW21 for project management, SPIE SAG for operations and installation, and Tvilight for the light management system (LMS).
As of March 2020, over 10.000 smart street lights have been already installed and fully operational. The solution saves over 50% energy, and it prevented over 300 tons of CO2 during the last 6 months through smart switching and dimming.
