The deployment of remotely controllable luminaires capable of real-time communication opens up new possibilities.

The lighting in bubbles of light

Light bubbles increase the light intensity of luminaires placed in the path of a pedestrian or cyclist. Thanks to sensors, this adaptation is done at the rhythm of the user’s movement, creating a real bubble of light that accompanies him. The interest is twofold: on the one hand, it improves the user’s visibility, but also reduces energy consumption. Indeed, the lights are only activated at full power when needed.

“The equipment was installed in mid-2021 so that the first tests of this technology could be carried out on a cycle track in Molenbeek. This requires quite a few adjustments to obtain good communication between luminaires and ensure optimal operation,” says Serge Lamborelle, Public Lighting Manager. Tests will also be carried out on the municipal street lighting in the Schuman Charmille eco-district in Woluwe-Saint-Pierre.

Towards dynamic public lighting

Tests were conducted during the summer of 2021 in the Bois de la Cambre to manage the municipal street lighting dynamically, based on public data available in real time. For example, the lighting level is automatically lowered in case of reduced traffic flow and if the weather conditions are good. In case of rain or strong wind (which may bring branches on the road), the lowering is not implemented. Here again, the main benefit is a reduction in energy consumption.

“Unfortunately, the health situation did not allow us to conduct the test as we had hoped. We are considering the possibility of organizing a new test on a larger scale,” says Serge Lamborelle.
