First installation of LumiNature

The LumiNature solution marks the beginning of a new era in human-centric lighting by creating artificial light that offers the same qualities as the Sun. LumiNature adapts to your biological clock by regulating the secretion of the right levels of melatonin, the sleep hormone, throughout the day.

THE BENEFITS FOR THE GUSTAVE ROUSSY INSTITUTE

In an environment with very little natural light, LumiNature recreates the Sun's light spectrum and provides wellbeing to medical staff and patients as well.

Combined with Sylvania's most efficient luminaires, the LumiNature solution offers visual comfort necessary for image analysis and avoids the fatigue inherent in standard lighting.

Respecting the circadian rhythm, LumiNature offers dynamic lighting that improves the comfort of patients as well as that of the staff working long hours.

The Gustave Roussy Institute, the leading cancer centre in Europe, benefits from the first installation of LumiNature, a true human-centred lighting solution.

The Department of Nuclear Medicine and Medical Imaging is located in underground spaces without outside light and subject to long working hours. Sylvania proposed a solution recreating natural light to increase visual comfort and efficiency at work.

"Thanks to Gustave Roussy Institute and its very specific architectural constraints, we had the opportunity to develop LumiNature, which is the first truly human-centric lighting solution, for the simple reason that it will recreate a natural light that regulates our melatonin production throughout the day, thanks to its specific wavelengths."  Yann Chevrier - Sylvania Project Manager

A MAJOR RENOVATION FOR THE IMAGING DEPARTMENT

Within the Gustave Roussy Institute in Villejuif, the Department of Nuclear Medicine and Medical Imaging includes waiting rooms, offices, classrooms and circulation areas. Only 10% of offices and spaces have access to natural light. Despite this constraint, the objective was to achieve the highest visual comfort throughout the long working days with large hourly amplitudes.

"For us, it seemed like a no-brainer to try this type of lighting that blew us away, especially by the colour rendering and the reproduction of the circadian cycle." Sébastien Genouvrier, Maintenance Works Manager.

After carrying out a lighting study by Sylvania, on more than 100 defined areas, 538 recessed luminaires integrating LumiNature technology were installed in the different spaces:

• Optix with very low luminance to illuminate all offices and meeting rooms
• Optix R8 Cells in linear version in circulation areas

Since the installation of the LumiNature solution, users have focused on comfort to view and interpret images in nuclear medicine without feeling tired. In everyday life, light has an extremely important impact on the quality of life and efficiency at work.

"In the morning, I arrive at the ultrasound lab, it is dark. I am in the dark all day. I leave in the evening, it is dark, especially in winter. And when I arrive in the morning and walk through this extremely luminous corridor, and finally, it gives us a good energy, a desire to give even more to patients. And I think it's a real benefit." Prof. Nathalie Lassau - Radiologist, Diagnostic Imaging

SUPPORT THROUGHOUT THE PROJECT

Combined with the SylSmart wireless lighting control system, the LumiNature solution makes it possible to reproduce the evolution of natural light and recreating a pleasing sensation of wellbeing throughout the day, both for medical staff and patients. Sylvania supported the Gustave Roussy Institute for the implementation and parameterisation of lighting and scenography for a result 100% adapted to the circadian rhythm. The circadian rhythm (or biological clock) and melatonin are intimately linked. Since melatonin production is dependent on the Sun, it is essential to be exposed to the right light at the right time of day. By working with our biological clock, LumiNature contributes to beneficial melatonin production of the human body throughout the day.

"So far, the feedback is unanimous from all the staff who would like to see precisely this type of technology developed throughout the building."

The LumiNature solution was developed in France, in Saint-Etienne, the factory where all the luminaires installed in the imaging and nuclear medicine area of the Gustave Roussy Institute were manufactured.
