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 Aurora Lighting Design, Inc., in Grayslake, IL, made the bold step of installing an OLED lighting system during office renovations in 2014, becoming the first office test site for the use of [...]

Below is my lighting column published in the July issue of tED Magazine. Reprinted with permission. Founded in 1992, the U.S. Environmental Protection Agency’s (EPA) ENERGY STAR is a voluntary product labeling program designed to help consumers identify and promote energy-efficient products. These products include lamps and residential luminaires. Consumers recognize the ENERGY STAR label [...]

The U.S. Department of Energy’s CALiPER program has released a new Snapshot report on linear LED lamps, commonly known as TLEDs. Among the key findings of the new Snapshot, which is based on DOE’s LED Lighting Facts database: TLEDs now comprise more than 50% of all listed lamps, and more than 10% of all listed [...]

JB MacKinnon’s article in THE NEW YORKER, “The LED Quandary: Why There’s No Such Thing as Built to Last,” available here, makes an argument for lighting product durability. (Cory Doctorow makes the case in short here.) As an example, he points to the “Light Bulb Conspiracy” of the early Twentieth Century, in which it’s alleged [...]

The National Electrical Manufacturers Association (NEMA) has published NEMA LSD 74-2016 Considerations of Field LED Driver Replacement. This whitepaper discusses issues related to the field replacement of drivers in LED luminaires and how several aspects must be considered to ensure that the replacement driver will function the same as the original driver. Developed by the [...]

David Shiller, President of Lighting Solution Development, LLC, recently blogged his top 11 takeaways from the 2016 Strategies in Light Conference. Socket saturation, OLEVs, price erosion, mini luminaires, R9 and more interesting observations here.

Below is my lighting column published in the June issue of tED Magazine. Reprinted with permission. The large majority of commercial building luminaires feature some type of optical system that controls the light emission. The type of optics employed ultimately determines where light is directed, how much light reaches that point, and with how much [...]

At Light + Building 2016, Philips research expert Marc de Samber introduced an external expert, Robert Karlicek, who made a presentation about technology trends and their impact on LED luminaires. Interesting stuff. Check it out:

New “TEN°” binning from Osram Opto Semiconductors provides the basis for extreme color consistency for white LEDs that are used as single-LED light sources in lighting solutions such as spotlights and downlights. To achieve this, the current standard CIE 1931 2° xy color space has been supplemented with CIE 2015 10° u‘v‘, recently developed by [...]
