Winners were recently announced for the first annual Next Generation Luminaires competition recognizing excellence in the design of energy-efficient LED luminaires for general illumination, white light in commercial lighting applications. Sponsored by the U.S. Department of Energy, the Illuminating Engineering Society of North America and the International Association of Lighting Designers, the competition was launched [...]

The National Electrical Manufacturers Association (NEMA) has published LSD 44 Solid State Lighting—The Need for a New Generation of Sockets & Interconnects. The white paper includes a background discussion of lighting sockets and interconnects, from the Edison bulb to the present. It argues for the necessity of standards on solid state lighting to foster technological [...]

Recently, I wrote a two-part series on LED lighting for Electrical Contractor that you might find interesting. The first article, titled “Lighting Up to the Legend: Will LEDs replace Traditional Sources of Light?”, acknowledges the importance of LEDs as an energy-saving light source with many other benefits, but notes that the technology is still rapidly [...]

Across the United States, local governments are slashing budgets, presenting significant challenges to local government. The city of Ann Arbor, Michigan suffered a 60% reduction, spurring the search for areas to cut costs, including the city’s energy use. The city was spending more than $1.4 million a year just on streetlighting. Ann Arbor embarked on [...]

Philips has announced its MASTER LED collection of LED lamps that can be used in luminaires with E27 and GU10 sockets. The 7W E27 A55 lamp, identical in form factor to a conventional light bulb, is most interesting, suitable for retrofit of 40W incandescents for nearly 83% energy savings in general lighting applications. The lamp [...]

Cooper Industries has announced the acquisition of Irvine, CA-based Illumination Management Solutions, Inc. (IMS). IMS is a developer of specialized optics and system design for LED luminaires. Terms of the transaction were not disclosed. IMS designs and manufactures LED systems and luminaires for a variety of lighting applications and has developed an innovation called LightBAR(tm) [...]

The Department of Energy has announced it will host a 90-minute live webcast on commercial building LED site lighting in parking lots, moderated by Linda Sandahl of the Pacific Northwest National Laboratory (PNNL). Eric Richman and Michael Myer from PNNL will supply an overview of a ew LED Site Lighting Performance Specification developed by DOE [...]

LumenPriority.org has announced the launch of its web site and interactive blog to present, discuss and explore the potential of applying feedback control of LEDs within solid-state lighting systems to stabilize lumen delivery through current regulation to compensate for light loss factors. This is the latest brainchild from friend and colleague Kevin Willmorth of Lumenique. [...]

Philips Lumileds has launched a free online tool that makes it easier for LED manufacturers to show compliance with ENERGY STAR standards. The tool addresses the requirements of the “Chromaticity and Spatial Uniformity” test for LED lighting that requires the beam of light to appear the same color to the human eye, regardless of which [...]
