LED + SSL

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 High-flux lighting applications in high-temperature environments present a formidable challenge for LEDs. The higher the luminous flux from a luminaire, the more difficult it can be to properly dissipate the heat, to [...]

This interesting presentation by Acuity Brands portrays OLED lighting as rapidly advancing in performance and poised for larger adoption. Check it out here.

The U.S. Department of Energy’s CALiPER program has released another special report on LED lamps that are available through the retail marketplace and targeted toward general consumers. CALiPER Retail Lamps Study 3.2 focuses on lumen depreciation and color shift in a subset of 15 LED A lamps from CALiPER Retail Lamps Study 3. The lamps [...]

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 Long lifetime ranks high on solid-state lighting’s list of potential advantages. But accurately predicting that lifetime is no easy matter, because — unlike most other lighting technologies — SSL has many different [...]

The U.S. Department of Energy (DOE) has released a new GATEWAY report that summarizes the results of a survey regarding conversions to solid-state lighting in museums. The survey was sent to members of the museum community who had requested a copy of “The Guidelines for Assessing Solid-State Lighting for Museums,” the pivotal resource co-authored by [...]

The Department of Energy has posted the presentations from its 2014 Detroit SSL Workshop. A lot of great presentations, particularly, “Specifying LED in a World of Continuous Change,” all available for free download 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 Greetings from Rochester, NY, where the OLED community — with some facilitating by DOE — is meeting to share updates on the efforts of a new OLED Coalition, explore basic science and [...]

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 As we approach a holiday that’s all about gratitude, I’d like to take this opportunity to express my personal gratitude to Shuji Nakamura, Isamu Akasaki, and Hiroshi Amano. In awarding the three [...]

Maury Wright, editor of LEDs Magazine, had an interesting editorial that started the November 2014 issue. Focusing on color-tunable white light and new form factors, he says LEDs are beginning to realize vast transformative potential, though there’s still work to be done. Of particular interest is what we know about light’s impact on human health, [...]
