LED + SSL

The National Academy of Sciences (NAS) has published a report, Assessment of Advanced Solid-State Lighting. The NAS committee reviewed the development and future impacts of SSL, including projections of cost and research and development (R&D) necessary to overcome barriers to widespread adoption. The report recommends: * Continue investments in LED core technology, aimed at increasing [...]

My lighting column in the April 2013 issue of ELECTRICAL CONTRACTOR addresses LED product maintenance. Over the past months, I’ve had the opportunity to work with the IES Maintenance Committee on revising RP36, and conducted extensive interviews with manufacturers and others about maintaining LED products. As you might suspect, they’re not quite maintenance free. Click [...]

The Department of Energy’s booth at LIGHTFAIR was hopping, with in-booth educational sessions packed with attendees. Experts addressed life-cycle assessment and environmental testing of LED products; performance of LED troffers, kits, and tubes; dimming and flicker; and provided updates on the L Prize® and Next Generation Luminaires competitions, LED Lighting Facts testing, CALiPER analysis, and [...]

Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, U.S. Department of Energy As you know, the 2013 edition of LIGHTFAIR International took place last week in Philadelphia, and the U.S. Department of Energy’s (DOE) SSL team was there in full force – staffing our booth, giving educational [...]

In his keynote at the 2013 LIGHTFAIR event, Vinod Khosla, principal of Khosla Ventures, presented, “Opportunities for Lighting in the Cleantech Revolution,” offering a cleantech investor’s perspective on how innovative approaches to lighting will transform this industry into potentially one of the most high-tech, creative and impactful sectors of the economy. What the lighting industry [...]

LED Journal recently published “The Impact of the ‘California Quality LED Bulb,'” an insightful article by Bernie Weir of ON Semiconductor on the impact of the new California Quality LED Lamp Specifications. Check it out here.

Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, U.S. Department of Energy This week, the U.S. Department of Energy’s (DOE) CALiPER program released an exploratory study on the problems and benefits likely to be encountered as LED products intended to replace linear fluorescent lamps and luminaires become [...]

The U.S. Department of Energy (DOE) has released an exploratory CALiPER study on the problems and benefits likely to be encountered as LED products intended to replace linear fluorescent lamps become increasingly popular. Eighteen lighting designers and facility engineers compared 24 identical pairs of troffers in a simulated office space. Three of those pairs involved [...]

The Telelumen Light Replicator enables any light to be recorded either in an instant or over time, matched by software, and reproduced.
