LED + SSL

Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, U.S. Department of Energy In two previous Postings and a Technology Fact Sheet, we’ve discussed the possible effects of LED lighting on our biological clocks. But a related question that has spawned a certain amount of confusion and misinformation [...]

To address the issue of how safe LED lighting is for the human eye, which has generated some confusion and misinformation, the U.S. Department of Energy has published a new fact sheet, Optical Safety of LEDs, which clarifies what’s known about the issue and provides information about current standards for photobiological safety. The main optical-safety [...]

Solais Lighting recently published an interesting whitepaper about causes and management of color shift in LED products. Download it here.

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 [...]
