DOE’s Municipal Solid-State Street Lighting Consortium (MSSLC) has released the results of a voluntary web-based inventory survey of public street and area lighting across the U.S., conducted during the latter half of 2013 and intended to improve understanding of the role of public outdoor lighting in national energy use. Results were based on the responses [...]

The U.S. Department of Energy has released a report on the longer-term performance of an LED lighting system that was installed on the I-35W Bridge in Minneapolis in September 2008 and represents one of the country’s oldest continuously operated exterior LED lighting installations. The report is a welcome addition to the literature on LED lighting, [...]

The 2014 edition of LEDs and the Worldwide Market for Lighting Fixtures is now available has been published by CSIL, including historical data up to 2013 and 2014-2018 forecasts. In less than 10 years, LED share on the lighting fixtures market worldwide jumped from 1% to 25%. In just five years, LED share will be [...]

Briteswitch recently sent me this nifty graphic outlining the current status of LED outdoor lighting rebate programs:

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 Among solid-state lighting’s many potential advantages, energy efficiency is the one that’s best-known, and it’s the driving reason behind DOE’s multipronged effort to accelerate the technology’s development and market introduction. That’s why [...]

The Next Generation Luminaires (NGL) Design Competition recently recognized 57 commercial LED indoor lighting products as part of its sixth annual awards program. Sponsored by the U.S. Department of Energy, Illuminating Engineering Society and the International Association of Lighting Designers, the NGL competition recognizes excellence in the design of energy-efficient commercial general lighting. In 2013, [...]

The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics for 2014 to Isamu Akasaki, Meijo University, Nagoya, Japan and Nagoya University, Japan; Hiroshi Amano, Nagoya University, Japan; and Shuji Nakamura, University of California, Santa Barbara, CA and one of the founders of Soraa, Inc. for “the invention of efficient [...]

When a fluorescent luminaire is upgraded to LED, what happens to its electrical safety certification? It depends on whether the new lighting is an LED luminaire, LED retrofit kit or LED replacement lamp. DOE has some guidance here. UL has some guidance here. Paraphrasing the documents, in a nutshell: All new components should carry proper [...]

Below is a reprint of an article about OLED lighting I contributed to the June issue of TED Magazine: Organic light-emitting diode (OLED) is an exciting novel lighting technology. Popular for small-screen display applications such as cell phones, it’s now rapidly developing as a commercial light source. The OLED source consists of organic (carbon-based) thin [...]
