The fifth annual Department of Energy Solid-State Lighting Manufacturing R&D Workshop, held June 5-6 in Boston, drew more than 150 attendees for two days of discussion. Topics included global LED and OLED manufacturing trends and strategies for reducing costs, improving product quality and increasing volumes. During the workshop, speakers and participants examined SSL manufacturing issues [...]

The U.S. Department of Energy recently released a new study addressing the potential environmental impacts from landfill disposal of three light-source technologies used in residential homes: incandescent, CFL and LED. All three lamp types contained some hazardous elements which, while generally below Federal landfill limits, in some instances exceeded the more restrictive California limits. The [...]

The U.S. Department of Energy (DOE) has published a technical feasibility assessment of replacing existing high-pressure sodium and low-pressure sodium roadway lighting on San Francisco’s Golden Gate Bridge, conducted through the agency’s GATEWAY demonstration program. The goal was to identify solutions which would reduce maintenance and energy use without compromising the quantity or quality of [...]

Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, U.S. Department of Energy One of the panel discussions generating buzz at DOE’s tenth annual SSL R&D Workshop, held a few weeks ago in Long Beach, CA, was the one that focused on light spectrum and color perception. As [...]

I recently produced a special section on LED lighting for the April issue of BUILDING DESIGN + CONSTRUCTION Magazine. Check it out in BD+C’s digital edition here (LF4-LF24, an insert between PP. 42-43).

The National Academy of Sciences (NAS) has published a report, Assessment of Advanced Solid-State Lighting. The NAS committee reviewed the development and future impacts of SSL, including projections of cost and research and development (R&D) necessary to overcome barriers to widespread adoption. The report recommends: * Continue investments in LED core technology, aimed at increasing [...]

My lighting column in the April 2013 issue of ELECTRICAL CONTRACTOR addresses LED product maintenance. Over the past months, I’ve had the opportunity to work with the IES Maintenance Committee on revising RP36, and conducted extensive interviews with manufacturers and others about maintaining LED products. As you might suspect, they’re not quite maintenance free. Click [...]
