Craig DiLouie, LC recently had the opportunity to interview David Ciccarelli, VP Dynamic Lighting, Acuity Brands Lighting, Inc. The topic: tunable-white lighting. DiLouie: Looking at LED sources and controls, what are the different technological methods used to produce tunable-white light in commercial luminaires? Ciccarelli: The goal of Tunable White lighting is to reproduce multiple color […]
ELECTRICAL CONTRACTOR recently published an article about advanced lighting controls, which you can read here.
As adoption of dimmable lighting grows, task tuning, a lighting control strategy, is becoming increasingly viable as a way to save energy while increasing occupant comfort. Also called “institutional tuning” and “high-end trim,” task tuning involves reducing lighting in a space based on IES-recommended maintained task light level requirements or user preference for individual spaces […]
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 […]
Lighting controls are now required by energy codes in the large majority of new commercial buildings. As demand for controls continues to increase, so does demand for commissioning as a quality assurance process. This process helps ensure that installed controls satisfy both the design intent and owner requirements by minimizing error across the construction process. […]
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 For years now, people have been talking about the “LED revolution” that’s being fomented by the disruptive technology that is solid-state lighting. But at DOE’s inaugural Connected Lighting Systems Meeting, held last […]
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 […]
EC&M Magazine recently published a short article identifying seven proven energy-saving lighting control strategies. Check it out here.
LED lighting can generate virtually any perceivable color as well as any shade of white light, all digitally controlled and selectable. Color output can be adjusted by mixing color LEDs, mixing white-light LEDs of different color temperatures, or a combination of the two. The key to achieving these effects is dimming. This allows, for example, […]
Typical automatic lighting control applications involve an input device, such as a photosensor, interacting with a power controller, such as a switch. In some cases, these components may be integrated into the same device, as in the case of a wall-box occupancy sensor. In other cases, the components are installed separately, as in the case […]
