Astronomy-friendly smart lighting on the Canary Islands


    15 March 2019


    Stargazers on the Canary Islands get an even better view of the night sky thanks to new connected Signify street lighting

    Light spillage is an issue for astronomers around the world. In fact, the Milky Way is hidden from 60% of Europeans and nearly 80% of North Americans. One place that has so far maintained pristine conditions to view the night sky is the Canary Islands.


    The islands provide such exceptional stargazing that they’re home to three Starlight Reserves and the Spanish government has put several lighting regulations in place to protect the quality of the sky.


    Puerto de la Cruz, on the north coast of Tenerife, was looking to balance the preservation of astronomy conditions with the provision of compliant, adjustable, and high-quality street lighting.


    As Lope Afonso, Mayor of Puerto de la Cruz says, “For astronomers and those who enjoy starlit nights, the quality of our skies is second to none. We want to preserve this precious resource and at the same time make our streets even safer for citizens and tourists.


    Enter Interact City, Signify’s connected LED lighting system and management software.

    Perfect lighting that preserves the dark


    In addition, working with experts from the Canary Islands Institute of Astrophysics (IAC), we developed special luminaire optics that are fully compliant with government-defined lighting regulations and certified by IAC. Light spillage is minimized, while the new optics also filter the blue part of the light spectrum, which could interfere with the activities of the observatories.


    In total, Signify installed over 6,000 light points, which are also wirelessly connected to the Interact City lighting management software, so they can be dimmed and controlled remotely.


    Additionally, the new lighting fixtures feature standard SR (System Ready) connectors, making them compatible with existing and new sensor applications. This means the city can also easily opt for new smart technologies whenever they become available.
