Randy Reid of the Edison Report conducted a great interview with Jim Brodrick on the history of the U.S. Department of Energy’s guidance and investment in solid-state lighting (LED + OLED). Brodrick led a fantastic program at the DOE that … Continue reading jim brodrick interview
I am thrilled to announce that Koerner Design has won a prestigious design competition hosted by the U.S. Department of Energy. The U.S. DOE’s Office of Energy Efficiency and Renewable Energy hosted a Manufacturing Innovator Challenge focused on the Sustainable … Continue reading koerner design wins US DOE sustainable luminaire design competition
As a United States citizen, I express my deep personal thanks to the entire team at the U.S. Department of Energy’s Solid State Lighting program for their vision, courage and tenacity in driving forward the entire lighting industry for the past 12+ years. The US DOE SSL recognized early in the technology cycle of LED’s — when white light LEDs barely yet existed — that they could have a tremendous impact on lowering the United States’ energy consumption. The DOE team provided a steady hand and plenty of common sense in their approach to the nascent technology, talking with numerous … Continue reading a special thanks to the US DOE
For us lighting nerds, a terrific webinar hosted by the US DOE discussing the state of the actual scientific research on street lighting and sky-glow sources, versus the extreme scare-mongering of recent “scientific” publications: Bruce Kinzey of Pacific Northwest National Laboratory … Continue reading US DOE street lighting “get the facts” webinar
The DOE continues their long term accelerated testing of the Philips L-Prize winning bulbs from 2010. The lamps continue to give shockingly good performance, with the average lumen maintenance for the 31 lamps at 93.0%. At that rate, the average operating hours … Continue reading go, baby go: the philips L-prize lamps rock on
The US DOE’s L Prize program has been conducting long-term testing of the 2009-vintage Philips 60W L Prize-winning LED A-lamps. The results are crazy impressive! A selection of 31 of those lamps passed the 40,000-hour point of continuous operation in July … Continue reading 194,765 hours to L70!
Check out the new fact sheet published by the DOE. It helps to clarify and dispel some of the myths surrounding LED lighting and its impacts on health. I think this paragraph is the perfect summary: What may be beneficial for an occupant during the day may be harmful at night, and may vary significantly between individuals in a given space. Complicating things even more is the need to balance the desire for alertness with preservation of normal circadian rhythms among night-shift workers, for example. Therefore, even if a prescription for effective nonvisual stimulation is developed, implementing the solution may … Continue reading U.S. DOE releases new fact sheet on light + health
As part of my ongoing effort to track innovative small companies in the lighting world (see this post and this post for some more ventures), here is a release from the U.S. DOE on their latest Small Business Innovation Research grants: Four SBIR Grants Awarded for SSL Technology (FY14 Release 2 Phase I) The U.S. Department of Energy Office of Science has awarded four Small Business Innovation Research (SBIR) grants targeting advances in solid-state lighting (SSL) technology. The FY14 Release 2 Phase I awards will explore the technical merit or feasibility of an innovative concept or technology. The SBIR and … Continue reading U.S. DOE SSL releases 4 SBIR grants
There is far more to sustainability in lighting technology then merely reducing energy consumption — so I’m thrilled to see that the U.S. Department of Energy’s Solid-State Lighting group has included a new section exploring the broader topic of sustainability in … Continue reading U.S. DOE includes sustainability in R+D roadmap
I recently presented at and attended the US Department of Energy’s Solid State Lighting 2014 R+D Workshop in Tampa, Florida. A terrific event, the US DOE’s SSL group uses this input from key industry participants to help guide their long-term funding programs with the goal of promoting the adoption of energy-efficient LED and OLED lighting technologies. The DOE has posted the presentation slides from each participant: You can find them here. And my specific slides here. We need to find ways to reduce the total costs of advanced lighting systems. And as big a fan as I am regarding digital lighting … Continue reading US DOE SSL R+D Workshop
Updated: Here is the link to the online article. LEDs Magazine has just published an opinion piece I authored urging the U.S. DOE and other groups to invest in R+D focused on Circular Economy strategies for the lighting industry. Follow … Continue reading LEDs Magazine: OP-ED regarding investment in sustainability
Our friends at the U.S. DOE Solid-State Lighting group just released a new study called the “Residential Lighting End-Use Consumption Study“. I’ll get to the punchline right away: A lamp in the average U.S. household typically runs only 1.6 hours … Continue reading 1.6 hours/day: do consumers need durable LED lamps?
The US DOE just issued a fact-sheet addressing the blue-light output of LEDs. It is a very good read for anyone concerned about this topic. The following two images are the crux of the document. The first chart shows the … Continue reading no, LEDs do not produce more blue light, so get over it
