LESA Center at Rensselaer Polytechnic Institute (RPI) 

The LESA (Lighting Enabled Systems & Applications ) Center is developing  intelligent systems to address  challenges in the connected environment such as  lighting systems with embedded intelligence from sensors that that automatically maximize light quality, minimize energy use by sensing occupant needs,  and controlling LED lighting to study circadian rhythms. Telelumen luminaires are a key component for the study of intelligent human centric lighting. 

Another lighting Testbed is located in the University of New Mexico Hospital. It conducts multi-day studies for gauging the effectiveness of light therapy to synchronize human circadian rhythms as a potential treatment for insomnia, mood disorders and other health problems. The Testbed uses color-tunable lighting from LESA industry member Telelumen.

Shown above at left is the Telelumen lighting system set to a mode enriched in the short wavelengths of the visible spectrum, above right is the same system but enriched in the long wavelengths.

The lighting in an intensive care unit (ICU) hospital room has been retrofitted in the Jefferson Hospital      for Neuroscience. The smart lighting system from Telelumen is potentially capable of adjusting spectrum and intensity in real time based on biometric feedback and human rest/activity cycles.  This facility will help elucidate how tunable architectural lighting can optimize the health of patients admitted to the ICU.

​​Telelumen Smart & Human Centric Lighting Applications

Founded in 1984 by renowned researcher George C. Brainard, PhD, Jefferson’s Light Research Program uses basic and applied science to study how various visible and nonvisible light sources influence human physiology and behavior. In Phase One of the Jefferson Hospital Lighting Initiative, the team has modified an ICU patient room in the Jefferson Hospital for Neuroscience
with a smart lighting system from Telelumen  (shown here).  

This next-generation space is enabling the researchers to perform controlled studies exploring the impact of LED lighting on patient health and recovery in the hospital setting.

The state of the art Telelumen Octa Light Player is ideal for accurate color evaluation in color critical applications. Meeting strict specifications and capable of reproducing international  standards like D50 and D65 (shown below) spectra, the Octa has been adapted for viewing booth configurations useful for photography and color evaluations.
