LED + SSL

The Department of Energy recently posted the workshop presentations and materials from its 2017 Solid-State Lighting Technology R&D Workshop, held November 8 in Portland, OR.

DOE has released a new report on a tunable lighting system installed at the Swedish Medical Behavior Unit in Seattle that sought to leverage biophilic design principles.

The U.S. Department of Energy’s GATEWAY program has released a new report on a trial installation of tunable-white LED lighting systems in three classrooms in the Carrollton-Farmers Branch Independent School District in Carrollton, TX, which provides valuable insights into the use of this technology in a real-world setting.

LEDucation 2018 planning is in full swing and you are invited to share your knowledge and expertise on subjects related to and about LED Lighting. Speaking proposals are due November 19, 2017.

Flicker is an old lighting issue diminished by the mass adoption of fluorescent electronic ballasts and returned with the advent of LED sources. Photometric flicker is the modulation of light source intensity or output over time. Here’s an update on industry efforts to tackle the challenge, with a focus on the recently published NEMA standard.

The National Academy of Sciences, Engineering, and Medicine (NAS) has published a report, Assessment of Solid-State Lighting, Phase Two, which is a follow-up to its 2013 report. The new report focuses on three key areas: commercialization (noting the rapid uptake of SSL since the 2013 report), technology development (updating the findings of the 2013 report), [...]

An industry working group facilitated by with the Department of Energy has published a new report on the impact of color shift on reliability. LED Luminaire Reliability: Impact of Color Shift was written to provide a better understanding of how and why color shifts. It does not define limits for specific applications. Developed by the [...]

At LIGHTFAIR 2017 in Philadelphia, DOE once again hosted an informational booth that offered free educational sessions to attendees. DOE has now made these presentations available for free download. They include: Connected Lighting Systems Efforts Michael Poplawski, PNNL NGLS Competition One: Installation and Configuration Evaluations Ruth Taylor, PNNL There’s Something About Red: Applying TM-30 in [...]

I recently had the pleasure of interviewing Dan Ryan, VP Product, IoT Solutions, Acuity Brands Lighting. The topic: disruption in lighting, notably the current trend of “bundling,” which was the subject of his presentation I caught at Strategies in Light. I’m happy to share his responses with you here. The interview informed an article I [...]
