The Center for Lighting Enabled Systems and Applications (LESA), at the Rensselaer Polytechnic Institute (RPI), and the Illumination Engineering Society (IES) sponsored a recent workshop to explore, define and promote the adoption of lighting systems in health care environments. The workshop brought together lighting and human health researchers, healthy-lighting design experts, senior representatives from health care standards organizations and health care providers. The aim of the workshop was to initiate an important discussion among diverse stakeholders on the changes in modern health care interior lighting applications. The result is the release of a white paper detailing the outcomes and contributions of the participants. "Today, the field of lighting and health care is undergoing rapid development," said Robert Karlicek Jr., director of LESA. "As research continues to build the link between lighting spectral power distributions and wellness, LED lighting technology strives to bring new healthy lighting to market. Often commercialization in this capacity happens without establishing the clinical data to demonstrate a value-added benefit for patients or the providers, or a defined return on investment for the health care industry." "It has long been known that lighting can impact human health and wellness," said Brian Liebel, director of technical standards at IES. "Research continues to refine the precise role of light spectrum, intensity, and timing on the scope of patient outcomes, and on health care worker productivity. But more research is required to provide the evidence necessary for new, modern standards for lighting systems in health care and eldercare markets." According to Karlicek and Liebel, the workshop white paper is intended to be an evidence-based resource for lighting designers and health care providers to better understand market drivers. Both noted that the white paper is a comprehensive introduction to insights shaping the field for participants attending the upcoming IES Light + Human Health Symposium in Atlanta. Funded by the National Science Foundation, LESA's vision is focused on creating digitized, color-tunable illumination for new applications in lighting, health care, building management, horticulture and advanced 5G wireless communications platforms.
