We are looking for an open and flexible lighting management system
"Decades of public lighting infrastructure has led to poor lighting and increased operating and maintenance costs. Inadequate lighting conditions also endanger public and traffic safety. We hope to solve these problems in an effective way. At the same time, we hope that Dortmund will use smart interconnected infrastructure Prepare for the future,” explains Mr. Meinolf Pflug from the Dortmund Civil Engineering Office.
"Cable infrastructure and cabinet switch points are not owned by the city, so they cannot be used to switch or control street lights. In addition, due to various infrastructure reasons, many street lights require 24 x 7 hours of power supply," Mr. Jan Wiesemann, project manager of lighting expert Trilux Added.
Dortmund went through an intensive planning and tendering phase. Meeting lighting and road safety requirements is naturally important. Costs and carbon dioxide emissions are also expected to be significantly reduced. The City Council also expressed a strong desire to make the public lighting infrastructure flexible and open for future use. In addition, smart lighting systems should be able to interoperate with other smart infrastructures and prepare for smart cities. "This process of extensive market exploration forms the basis of Dortmund's new lighting system specifications," Mr. Pflug concluded.

Individual lighting control provides unprecedented flexibility
"The wireless smart lighting system was selected as the most favored solution. As a comprehensive solution, it can improve lighting and safety, reduce costs and reduce carbon dioxide emissions. Due to the openness and flexibility of the system, it It also lays the foundation for hosting an innovative system that helps us become a smart city,” explained Mr. Pflug. "Single light management and control provides unprecedented flexibility", Mr. Wiesemann added.
The 25.000 street lights in Dortmund (the eighth largest city in Ruhr in Germany) are being converted from traditional street lights to state-of-the-art LED street lights, which also include smart lighting control. Project partners include Trilux for LED street lights, DEW21 for project management, SPIE SAG for operation and installation, and Tvilight for lighting management systems (LMS).
As of June 2021, more than 16.000 smart street lights have been installed and fully put into use. This solution saves more than 50% of energy and reduces more than 300 tons of carbon dioxide in the past 6 months through smart switching and dimming.
