University Hospital in Poitiers, France Uses Human-Centric Lighting with LED Modules and Drivers from Tridonic

The newly-installed lighting installation at the university hospital in Poitiers, France supports the health and well being of cancer patients at the hospital in a special room that employs human-centric lighting. The 1900-bed university hospital of Poitiers serves as the central healthcare provider for the entire Vienne region of France.

The special room uses tunable white LED technology and a custom-designed ceiling to simulates a natural environment. In addition, more than 800 Tridonic LED luminaires and LED drivers were installed in the hospital’s new administrative block.

As part of inter-regional projects and partnerships with other university hospitals, it researches, tries out, and studies medical and therapeutic innovations, improvements to clinical processes, and methods of improving patient experiences and outcomes.

Human-Centric Lighting Intended to Support Cancer Treatment

Biologically effective light is being tried in modern medical facilities with the intention of ensuring the optimum well-being of patients and giving them with a more pleasant hospital stay. This type of lighting that attempts to improve health and well being is often referred to as human-centric lighting.

Such lighting solutions include lighting that is intended to boost a patient’s recovery and has been shown in studies to improve sleep length and quality. For this reason, human-centric lighting was recently deployed in the oncology department of the university hospital of Poitiers to potentially enhance cancer treatment.

For the installation, Tridonic QLE PREMIUM modules with tunable white technology were mounted on the ceiling. The tunable white technology of these square LED modules can adjust the color temperature of 3,000 to 6,000 K at constant luminous flux and can dim the lights down to 10 of their intensity without changes to the chosen color temperature. The printed light ceiling shows a picture of the sky. The ceiling luminaire is controlled via the Tridonic connecDIM light management system.

The LED modules are connected to the cloud via an internet-capable gateway, which enables decentralized control of the light.

The hospital’s Technical Services department employed this system to create one hundred predefined schedules with different color temperatures and dimming levels so that the lighting would mimic the color temperature changes in natural daylight throughout the day. Slow movements and color changes create the association with a natural sky.

Following positive feedback from doctors, nurses, and patients, the same lighting system was soon installed in front of the elevators on the ground floor which had no natural light.

According to Tridonic, the new installation generates a brighter and more pleasant atmosphere and makes navigation easier. Visitors can tell from the image of the sky that they are on the ground floor because this area now differs markedly from the elevator areas on the other floors.

LED lighting for New Administrative Building

The new administrative building at the university hospital was furnished with over 800 SUNA LED luminaires from Tridonic’s partner SFEL. The building combines all the administrative departments under one roof to improve internal processes and coordination.

Tridonic says that new lighting technology is reducing energy costs. The linear luminaires installed in the offices, open-space areas and meeting rooms are equipped with Tridonic LLE G3 LED modules and also use Tridonic Premium drivers. The small spacing between the light points ensures that the luminaires emit homogeneous illumination along their entire length. Each luminaire features a compact basicDIM control module. The compact control module contains an ambient light sensor that automatically adjusts the light intensity according to how much natural light is available at the time. Also an integrated motion sensor automatically switches the light on or off depending on whether or not the workstation or room is currently occupied. This motion sensor generates further energy savings.

Tridonic asserts that the new lighting solutions at the hospital can improve the well-being of patients and visitors and also the working environment of the employees. Furthermore, the company claims that the operators of the new administrative building are benefiting not only from optimum lighting but also from cost savings due to integrated sensors.
