A new, efficient light-harvesting system based on the principles of natural photosynthesis has been developed by researchers at Tokyo Tech. Scientists have long been trying to emulate the way in which plants harvest energy from the sun through photosynthesis. Plants are able to absorb photons from even weak sunlight using light antennae made from chlorophyll [...]

Maury Wright, editor of LEDs Magazine, had an interesting editorial that started the November 2014 issue. Focusing on color-tunable white light and new form factors, he says LEDs are beginning to realize vast transformative potential, though there’s still work to be done. Of particular interest is what we know about light’s impact on human health, [...]

New York Governor Cuomo recently signed into law the “Healthy, Safe and Energy Efficient Outdoor Lighting Act,” which establishes requirements for outdoor lighting installed by state agencies. The bill requires the use of properly shielded luminaires to prevent unnecessary up- and side-lighting, thereby reducing light trespass and sky glow. The bill also states that installations [...]

In November 2014, ASHRAE published ANSI/ASHRAE/USGBC/IES Standard 189.1, Standard for the Design of High-Performance, Green Buildings Except Low-Rise Residential Buildings. The standard, which updates the previous 2011 version, covers site sustainability, water use, energy, indoor environmental quality, and the building’s impact on the atmosphere, materials and resources. The standard provides states and other jurisdictions a [...]

In a press release, lighting artist Bentley Meeker, president of Bentley Meeker Lighting Staging, Inc., contends what we don’t understand about light is affecting our health. He says: “LEDs and fluorescent are the same light from a spectral standpoint. Daylight and halogen (or incandescent) light are similar in spectral properties. And daylight and firelight are [...]

The Lighting Research Center has produced a new video, featuring director Mark Rea, proposing lighting value metrics that look beyond cost and lumens and focus on application needs.
