Lighting system that automatically adapts to users’ perception

As part of the SceneUnderLight project, launched in 2015, Osram, together with the Veronese University and Istituto Italiano di Tecnologia (IIT) in Genoa, has successfully combined advanced research in the field of computer vision and modern lighting technology to create what the company describes as an invisible light switch .

Using the latest technology to estimate light spread in real-time offices and calculating how many people perceive, the invisible light switch automatically adjusts the lighting based on the presence of people and their position within the office. Especially in large open-type offices, distant lighting bodies can be silenced without changing the comfort of employees and their sense of security.

According to Osram, the invisible light switch allows every person in the office to see the whole office as “all lit.” while lights that are not visible or seen from their position are off. This approach offers up to 65 percent of energy savings. SceneUnderLight funded the EU within the framework of the Obzor 2020 framework as Marie Skłodowska-Curie’s project.

Fabio Galasso, head of the department for research and development of computer vision at Osram, has assembled a team consisting of Marc Cristani, head of the Department of Vision, Processing and Sound of the University of Verona and Alessio Del Bue, the head of the Visual Engineering Geometry Laboratory and IIT Modeling. By 2015, project members aim at two main goals: understanding the structure of light and scenes in the office, as well as understanding the human factor in the illuminated scene.

IIT has provided a unique expertise in 3D light assessment in large and complex office scenes, from the color and depth of the picture provided by the modern RGB-D camera. The University of Verona has provided expert knowledge and designing skills to evaluate people’s views and their future motion with the deep neural network model.
