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 The emergence of high-frequency electronic ballasts for use with fluorescent lighting did away with most general-illumination flicker concerns back in the 1990s. That is, until the advent of LEDs, which have put [...]

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 The efficacy of LED lighting products has already surpassed that of traditional technologies for most applications, but there remains significant headroom for improvement. DOE has set ambitious efficacy targets for SSL, and [...]

The U.S. Department of Energy (DOE) has released its latest report in a series analyzing markets where LEDs compete with traditional lighting sources. The new report, Adoption of Light-Emitting Diodes in Common Lighting Applications, estimates penetration into the installed lighting base in 2014 in 10 popular lighting applications. DOE also estimates 2014 energy savings as [...]

IHS Electronics360 recently reported on the transition to LED technology in the global lighting market. They reported: * LED lamp revenues were 30% of the global lamp market in 2014, up from 25% in 2013 * LED market share in global lamp market expected at 67% in 2022 * Philips is worldwide market leader in [...]

I recently had the pleasure of interviewing Jeannine Fisher Wang, PE, LC – Director Business Development, Acuity Brands. The topic: OLED lighting–where it is now, where it’s going. I’m happy to share her responses with you here. The interview informed an article I wrote for the November issue of tED. DiLouie: How would you characterize [...]

ENERGY STAR is a voluntary testing and labeling program that verifies that energy-efficient lighting products provide comparable performance as incumbent-technology products while saving energy. ENERGY STAR is used as a qualification for product rebates by a number of utilities. On June 1, the EPA released the new (final) Luminaires v2.0 spec, which will replace v1.2 [...]

I wrote this article for the July issue of tED Magazine. Reprinted with permission. LED performance continues to increase, making it increasingly competitive with traditional lighting, while costs continue to fall, making it increasingly attractive for purchase. According to the U.S. Department of Energy (DOE), between 2005 and 2013, average efficacy of cool-white LED packages [...]

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 There’s a growing awareness of glare these days, both within and beyond the lighting community. Glare can be a problem with any lighting technology, but the nature of LEDs as point sources [...]

I was pleased to contribute a special editorial section on LED lighting to the April issue of BUILDING DESIGN + CONSTRUCTION. It includes an article about the state of the art in LED luminaires, new products plus a tour of several design projects exemplifying the effective use of LED lighting. Click here to check it [...]
