DOE Publishes Updated Recommendations for Testing and Reporting LED Luminaire Lifetime

The U.S. Department of Energy (DOE) has published an updated version of the guide LED Luminaire Lifetime: Recommendations for Testing and Reporting, the latest edition in a series of publications on LED product performance and lifetime. The guide was developed by a working group under the auspices of DOE and the Next Generation Lighting Industry Alliance, composed of a diverse group of experts in reliability, lighting, and LED technology. Their recommendations are an important step toward consistent, industry-wide understanding of LED luminaire lifetime, and will assist standards organizations in their work. Read more »

Studies Published on Flicker Perception from SSL Systems - ASSIST to Release Related Recommendation

The contour plot figures below show mean detection percentages (left) and mean acceptability ratings (rigth), both as a function of frequency and percent flicker (click on image to see the full plot) Flicker and stroboscopic effects have been a concern with solid-state lighting (SSL), and industry and the ENERGY STAR program have debated recently the effects of frequency and other driving modes on the perception and acceptability of flicker. To provide further data and guidance in this area, the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute has conducted human factors studies of flicker that were recently published in the Lighting Research and Technology journal. The studies, funded by the Alliance for Solid-State Illumination Systems and Technologies (ASSIST), will become the basis for future ASSIST recommends guidelines on flicker from SSL systems.

UCI Researchers Find LED Products Billed as Eco-Friendly Contain Toxic Metals

LED products usually are electronic products that should be handled as electronics scrap if disposed, anyway. A realease of potentially hazardous substances under regular use is very unlikely, even when broken. LED professional does not agree with the generalized conclusions of this research. However, it is important to challange statements of PR and lobbies to boost more eco-friendly products. In fact, light-emitting diodes of tested holiday bulbs, traffic lights and car beams marketed as safe, environmentally preferable alternatives to traditional lightbulbs actually contain lead, arsenic and a dozen other potentially hazardous substances, according to newly published research.

DOE Releases SSL Manufacturing R&D Roadmap

The U.S. Department of Energy has published the 2010 edition of the Solid-State Lighting (SSL) Manufacturing R&D Roadmap. Complementing the SSL R&D Multi-Year Program Plan (MYPP) that guides the Core and Product Development R&D programs, the Roadmap's primary goal is to guide the manufacturing R&D program and help direct funding solicitations for it. Manufacturing R&D is a part of DOE's SSL manufacturing initiative launched in 2009. The Roadmap also provides guidance for equipment and material suppliers, based on industry consensus on the expected evolution of SSL manufacturing – thereby reducing risk, improving quality, increasing yields, and lowering costs.

New DOE Report Estimates Energy Savings Potential of SSL

The U.S. Department of Energy (DOE) has released analysis findings of the energy savings potential of solid-state lighting (SSL) sources for general illumination applications compared to conventional light sources (e.g., incandescent and fluorescent). Using an econometric model of the U.S. lighting market, the February 2010 report estimates national energy savings if SSL technology achieves certain forecasted price and performance objectives.

DoE Released New CALiPER Program Results: Round 7 of Product Testing

DoE released CALiPER Program round 7 results. The testing focused on three application areas: outdoor lighting, downlights, and replacement lamps. One series of tests included eight streetlights. The series of tests on nine downlights included a wide range of luminaires that could potentially be used for downlighting. The replacement lamp category included nine different SSL products, including: MR16s, some larger directional lamps (PAR20, PAR30, and PAR38), and A-lamps. Read more »
