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 You may recall that last year, DOE’s GATEWAY program released a report entitled Dimming LEDs with Phase-Cut Dimmers: The Specifier’s Process for Maximizing Success, which was created in response to issues raised […]
The U.S. Department of Energy has revised its October 2013 report, Dimming LEDs with Phase-Cut Dimmers: The Specifier’s Process for Maximizing Success, to include updated information about the installation of LED lighting and controls at the Burden Museum in Troy, NY, a GATEWAY project that was still in construction when the original report was published. […]
Outdoor lighting controls is undergoing a mini-revolution that offers new design and selling opportunities while challenging electrical professionals to stay on top of technological change. Traditionally, outdoor lighting control was relatively simple. A typical scheme featured a controller providing automatic ON/OFF based on time of day (using an astronomical time switch) or daylight (photosensor). The […]
The U.S. Department of Energy’s CALiPER program has released Report 20.2, which is part of a series of investigations on LED PAR38 lamps. Report 20.2 focuses on dimming, flicker and power quality characteristics evaluated with a single dimmer. The dimming, flicker and power quality behavior of the LED PAR38 lamps evaluated in this study was […]
Visible light communication (VLC) is a wireless method that uses light emitted by LEDs to deliver networked, mobile, high-speed communication similar to Wi-Fi, leading to the term Li-Fi. It can be used as standalone solution or in a supplementary role to radio-frequency (RF) or cellular network communication. The basis of the technology, conceived by Professor […]
Unlike fluorescent loads, most LED products are inherently dimmable. However, the dimming performance can vary greatly from manufacturer to manufacturer, or even in different fixtures from the same manufacturer. Additionally, the fast-moving state of the LED lighting industry means there is a lot of risk that needs to be managed throughout a job. In response, […]
ARCHITECTURAL LIGHTING recently published an article about how the LED revolution opens new possibilities for luminaires to serve other functions such as lighting control, surveillance and other services. Check it out here.
With efficacy and service life steadily increasing and costs declining by about 18 percent each year (Memoori, 2014), the LED revolution continues to develop at a rapid pace. LED’s inherent compatibility with digital control, aided by other trends, is setting the stage for the next LED revolution: smart lighting control. Many LED products are sold […]
Lutron’s Dr. Pekka Hakkarainen recently wrote an article for LEDs MAGAZINE that makes the case that further LED adoption depends on advanced lighting controls. Check it out here.
The Illuminating Engineering Society, in partnership with the Lighting Controls Association, has published LEM-7, Lighting Controls for Energy Management, a detailed guide to energy-saving lighting controls. The publication was written by Craig DiLouie, LC in support of the IES Energy Management Committee. The 48-page 8.5×11 guide, which is available for $35 (IES members) and $50 […]
