Jim Brodrick on the Nobel Prize in Physics

Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, SSL Program Manager, U.S. Department of Energy As we approach a holiday that’s all about gratitude, I’d like to take this opportunity to express my personal gratitude to Shuji Nakamura, Isamu Akasaki, and Hiroshi Amano. In awarding the three […]

The Nuckolls Fund for Lighting Education Issues Call for Proposals

The Nuckolls Fund for Lighting Education, an endowment fund in support of college-level programs that inspire students with an understanding of light in architecture, has issued a call for proposals. E ach year, the Fund solicits proposals from colleges and universities for innovative educational ideas consistent with the Fund’s objectives, and awards grants after rigorous […]

Product Monday: Split by Luxo

Luxo’s Split doubles the light output of the typical task light for larger, more demanding applications. The aluminum luminaire features two 6W LED modules, each positioned at 30 degrees for wide light distribution of desktops, while the luminaire head itself remains parallel to the work surface. Dimmable, available with integrated PIR occupancy sensor. Click here […]

Light Harvesting: Mimicking Photosynthesis with Artificial Leaves

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 […]

The Vast Potential of LEDs

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’s Governor Cuomo Signs Model Outdoor Lighting Bill Into Law

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 […]

Green Building Standards and LEED to Harmonize

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 […]

Are LED Trends Affecting Our Health?

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 […]

LRC Releases Video Proposing Lighting Value Metrics

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.
