The module utilises 18 LEDs to generate multi-zonal light to provide tailored pathway illumination
Graz has partnered with Zumtobel Group Services (ZGS) to install intelligent luminaires in part of the public garden (Volksgarten) in the Austrian city in a bid to enhance public safety.
The pilot deployment involves six Supersystem outdoor luminaires with vandal-resistant fittings that deliver high levels of light and smart connectivity.
Motion detectors and noise sensors control the light by responding to movement and noise and then emit more light as and when required.
The luminaires are controlled via InCity from ZGS – an intelligent web-based lighting controls system. InCity activates the fittings via a radio module when the sensors detect noise or movement. The accompanying software also displays the energy savings achieved by the new lighting solution, as the pilot project is currently saving around 60 per cent energy, ZGS claims.
The fittings are dimmed for most of the night, yet even at full output, Supersystem outdoor requires around 20 per cent less energy than the original luminaries, according to ZGS. A nearby gateway enables communication between the luminaires and the web server.
Mounted at a height of 4.5 metres, the luminaires are installed significantly higher than the previous light points in the garden. The square pole is more difficult to climb and the compact light-output points with a small contact surface are less prone to vandalism. The latest LED technology delivers a warm-white light and reduces light pollution.
The module utilises 18 LEDs to generate multi-zonal light to provide tailored pathway illumination.
The system in the Volksgarten has the option of being upgraded in the future, as the Graz authorities have the option to control the lighting centrally and remotely using dedicated software. This could be useful if, for example, the police are called in to deal with an incident in the public garden.
InCity also supports the collection of additional information about factors such as noise levels, weather conditions and the identity-free movement of people. Analysis of this data may eventually offer further useful opportunities, said ZGS. For example, showing the most popular routes across the park could facilitate more efficient cleaning and snow clearance work.
“This pilot project has demonstrated how we can bring the park into the digital age – and, in doing so, actively maximise safety,” said Siegfried Nagl, mayor of Graz. “There hasn’t been any vandalism in the park area since the new luminaires were installed.”
