LED + SSL

Shirley Coyle, President of Cree Canada, recently contributed her thoughts to Lighting Design & Application in response to a request to chime in on the American Medical Association’s recent guidelines for LED outdoor lighting. She points out that basing recommendations on correlated color temperature (CCT) is flawed: On the issue of safety, the most obvious [...]

Earlier this year, the Department of Energy hosted its 14th annual Solid-State Lighting R&D Workshop. Over three full days, 250 attendees participated in sessions covering LED and OLED technology. Presentations from 60 experts addressed the complex science and technology challenges facing SSL today, as well as innovative new ways to improve manufacturing processes, reduce costs [...]

DOE has published the results of a study of the expected contributions to sky glow from converting high-pressure sodium (HPS) street lighting to broader-spectrum (i.e., white light) sources, with specific focus on LEDs, and presents the contributions in a manner relative to HPS baseline conditions. These conditions represent typical conversions in the U.S. and include [...]

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 Although I recently spent a week at the beach, there was no sand, surf, or bathing suit in sight. That’s because I was in Long Beach, CA, at DOE’s 14th annual Solid-State [...]

The U.S. Department of Energy’s CALiPER program has released a new Snapshot Report on LED industrial luminaires, based on DOE’s Lighting Facts database. Key findings: • The efficacy of LED industrial luminaires is notably higher than what’s typical of their incumbent counterparts. About 23% of the industrial luminaires listed with LED Lighting Facts listed products [...]

My contributions to the February issue of ELECTRICAL CONTRACTOR included an extended feature on tunable-white LED lighting, covering color basics, product types, color quality, control and applications. Check it out here.

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 Troffers are a staple of the lighting industry, providing economical ambi¬ent lighting in offices, schools, and commercial spaces. They come in a variety of form factors — typically 2×4, 2×2, and 1×4 [...]

I recently had the pleasure of interviewing Eric Marsh, Product Porfolio Manager, and Jeff Hungarter, Senior Manager, Product Marketing, Cree, Inc., for an article developed for tED Magazine. The topic: LED options for upgrading fluorescent troffers. I’m pleased to share the interview with you here. DiLouie: What basic choices do building owners have to upgrade [...]

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 Last year, DOE devoted two Postings (in June and October) and a webinar to the topic of LED street lighting and its potential effects on human health and the environment, in order [...]
