Intelligent lighting and the smart city

    Düsseldorf, Germany
    The city of Düsseldorf relies on Interact


    The city of Düsseldorf wants to become climate-neutral by 2035 and develop into a smart city. Because public lighting is of central importance for this initiative, the city is relying on the potential of Interact.

    “If we illuminate public spaces better and bring light to where it is actually needed, this directly increases the quality of stay and is a key factor in a smart city.”


    Florian Fuchs, Smart City Expert, Stadtwerke Düsseldorf AG

    Customer challenge


    After the city of Düsseldorf had negotiated a new lighting contract, Stadtwerke Düsseldorf, the municipal energy supplier, searched the market for technologies which would help them achieve their goals. The aim was to achieve demand-based lighting control in order to improve the quality of life and the quality of stay within the state capital on the one hand, and to significantly reduce the energy consumption and CO2 footprint of the lighting on the other. Interact from Signify made this possible.

    The solution


    In close cooperation with Signify, Interact was initially tested as part of a pilot project on Düsseldorf's Fürstenwall. The technicians responsible were particularly impressed by the flexible individual luminaire control and the lighting quality of the networked Philips LumiStreet luminaires, which work seamlessly with Interact. The transition to Interact connected lighting began in 2022, with over 3,000 public light points networked so far. 50,000 luminaires are still using conventional technology and need to be upgraded. The city plans to renovate 3,000 light points per year to achieve their digitalization and climate goals by 2035.



    Following a successful test phase, the technology is now being introduced throughout the city of Düsseldorf. 3,000 public light points have already been added to the Interact system, with 50,000 more to follow. As part of the conversion, all of Düsseldorf's switching points will be digitized and converted to Interact.
