The Pacific Northwest National Laboratory (PNNL) recently published a new report analyzing the energy impact of lighting designs that satisfy three prominent circadian lighting guidelines. The researchers discovered a potentially significant increase in light levels and associated energy consumption.

Frost & Sullivan’s recent analysis, 2020 Annual Update of Global LED Lighting Market, finds that the increasing demand for energy-efficient lighting, the rising number of smart city projects and overall infrastructure development are driving the LED lighting market across the globe.

The U.S. Department of Energy (DOE) recently released a study investigating age-related changes in LED device efficiency and optical performance.

Researchers with the U.S. Department of Agriculture’s (USDA) Wildlife Services (WS) program recently applied for a patent (U.S. Patent Application No. 16/668,253) for a new vehicle-based lighting system to prevent deer-vehicle collisions during low-light conditions.

Researchers at the Advanced Research Center for Nanolithography (ARCNL) have produced a method of using light to induce high-frequency sound waves, which in turn are used to reveal the internal structure of opaque materials in very small structures such as semiconductors.

Researchers from Israeli’s Ben-Gurion University of the Negev and the Weizmann Institute of Science have discovered a new technique for long-distance eavesdropping on voice conversations by observing tiny vibrations these sounds make on the glass surface of a visible lamp.

The COVID-19 pandemic has spurred fresh interest in UV-C as a way to disinfect objects and surfaces. Signify and the National Emerging Infectious Diseases Laboratories (NEIDL) at Boston University conducted research that demonstrates effectiveness of the company’s UV-C light sources on the inactivation of SARS-CoV-2, the virus that causes COVID-19.

The Pacific Northwest National Laboratory (PNNL) recently released the results of a U.S. Department of Energy-funded study, Measuring Light Exposure and its Effects on Sleep and Behavior in Care Center Residents.

The Lighting Research Center (LRC) at Rensselaer Polytechnic Institute is investigating light-based disinfection using short-wavelength light, ranging from ultraviolet (UV) to blue light (200 nm to 410 nm).
