The National Electrical Manufacturers Association (NEMA) published NEMA SSL 7A-2015 Phase-Cut Dimming for Solid State Lighting—Basic Compatibility. This standard provides compatibility requirements when a forward phase-cut dimmer is combined with one or more dimmable light-emitting diode (LED) light engines (LLEs). An LLE, for the purposes of this document, comprises one or more LED modules, LED […]
ARCHITECTURAL LIGHTING recently published an article by Clay Risen, “Seeking Compatibility in the LED Era,” that begins: The transition from conventional to solid-state lighting components is still far from plug-and-play—and the lack of universal standards is not helping. Read it here.
Ethan Biery, LED Engineering Leader, Lutron Electronics, recently contributed a very good article to LEDs Magazine about the current struggle to establish good metrics to characterize flicker. From the article: The evolution of LEDs in the lighting market has not always been smooth, but the technology has come a long way since the early days. […]
Craig DiLouie, LC recently had the opportunity to interview Audwin Cash, VP Acuity Controls Solutions, Acuity Brands Lighting, Inc. The topic: controlling LED lighting. DiLouie: How are LED sources different from traditional sources in terms of controllability and behavior while controlled? Cash: LED sources are the first economically viable solid state light source. LEDs, paired […]
The U.S. Department of Energy’s inaugural Connected Lighting Systems Meeting, held November 16 in Portland, OR, saw more than 260 experts from the lighting, semiconductor, and IT industries gather to share perspectives and lay the groundwork for government/industry collaboration on the convergence of intelligent controllable light sources, communication networks, sensors, and data exchange in future […]
Alumage Advisors has released its latest LED Smart Lighting Report, including a free version for end-users, highlighting 40 product features of interest for 1,000 commercial and industrial (C&I) luminaires worldwide. “Since introducing our first reports in 2013, we added a smart lighting focus, as 77% of the products we track are dimmable, 59% offer motion […]
In an article recently published by LEDs Magazine, Lutron Electronics’ Roland Ledyard explains that while 0-10V dimming is a standard driver feature, every technology decision has a cost. He makes an argument that digitally addressable drivers are often a more economical decision. Click here to read the article.
The National Electrical Manufacturers Association (NEMA) published NEMA LSD 73-2015, Energy Savings with Fluorescent and LED Dimming. This new white paper describes the signal path from the user control input through the control wiring, ballast or driver, and lamp or LED module. It also explains factors that affect energy consumption and savings, efficacy and user […]
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 mentioned in these Postings a few weeks ago, the biggest takeaway from this year’s LIGHTFAIR® International was the prevalence of connected products, and the fact that sensors and controls seemed […]
Visible light communication (VLC) is a particularly exciting technology in an industry that is already going through exciting technological change. This technology, popularly used in applications such as fiber-optics, now shows promise for general lighting due to the advent of LED lighting. The potential is to create spaces that actively communicate with users. What is […]
