Light + Health

The Journal of Post-Acute and Long-Term Care Medicine (JAMDA) recently published a research study showing long-term care facility falls were reduced 43% by changing light spectrum and intensity throughout the day for residents.

The U.S. Department of Energy has released two reports which characterize the current state and viability of commercial ultraviolet (UV) LED products.

Randy Reid and Katie Smith recently published an article on LinkedIn, about UL’s latest moves into circadian lighting.

Signify’s NatureConnect natural lighting system mimics the natural patterns of daylight indoors to create a unique daylight experience. The intensity and shadows change throughout the day. It creates interesting lighting scenes designed to reconnect people with daylight cycles, and bring the outdoors in.

In a newly published study, researchers from Binghamton University’s Thomas J. Watson College of Engineering and Applied Science answer many of the questions about UV disinfection of the virus that causes COVID-19, and lay the foundation for health standards about what offers true disinfection.

A recent LD+A article discusses the significant growth projected in the hospital lighting market. Research and Markets unveiled in their Hospital Lighting-Global Market Trajectory and Analytics report that the global market is expected to reach $8.5 billion by 2027,

LIGHTGLASS is a windowlight, an architectural element that brings the experience of a daylit window into any space. Through the integration of the latest LED lighting technology into the form and materials of a window, LIGHTGLASS is nearly indiscernible from a real window.

Linda Longo, at US Lighting Trends, summarized the issues involved in proposed legislation to make Daylight Savings Time permanent and year-round, in the US.

Mark Halper has an interesting article in LED’s Magazine interviewing Russell Foster, the scientist who predicted the non-visual receptors in the eye that are involved in the circadian response to light (pRGCs / ipRGCs). He says circadian lighting science isn’t ready yet, and there are too many unknowns.
