wiring-1Control wiring provides a path for command and status communication between control devices in a lighting and control system and, in many cases, power to the devices as well. Wiring is interrelated with overall lighting control system considerations—such as selection of control system and components, layout and installation practices—and is therefore an important consideration when choosing a lighting control solution.

This is the subject of a new whitepaper I wrote for the Lighting Controls Association, which has been published on the organization’s website. You can read it free here.

ecostep_logoLedalite’s ecoSTEP program highlights new product options and corporate initiatives that support the company’s ongoing sustainability commitments. Available in all Ledalite 2’x2′ recessed luminaires, the ecoSTEP offering delivers energy savings of 25%-35%, with 68% less mercury content, and requires less maintenance and fewer luminaires for a wide range of open plan spaces including libraries, offices and public areas. The 25W Philips Energy Advantage lamping option provides significant energy savings and reduced environmental impact. This new option boosts fixture efficiencies as high as 87% and is available with Ledalite’s Pique, PureFX, Vectra, and Voice recessed product families on the 10-day QuickShip program. For maximum savings, ecoSTEP products are optionally available with Ledalite’s integrated Response daylight harvesting sensors to reduce energy consumption. In addition, ecoSTEP luminaires are provided with an extended 5- year total system warranty on the fixture, ballast, and lamp.

airwave_exterior_overviewAirwave, an innovative wireless lighting control technology, is also a key component of Ledalite’s new ecoSTEP program. With no hardwires and no batteries required to operate, Airwave kinetically powered switches and solar powered photosensors can significantly reduce the amount of copper wiring infrastructure required in a facility by up to 30%. Using renewable organic energy sources, Airwave wireless devices provide individual personal control, daylight harvesting, occupancy sensing, and full range dimming for private offices, open plan areas, conference rooms, and other spaces where the ability to control energy and lighting are essential.

Over a year ago, a group of building controls manufacturers formed the EnOcean Alliance to promote interoperable wireless sensor networks based on the EnOcean wireless standard. Today, 113 companies, including Leviton, Masco, Distech Controls, Philips Ledalite and Osram Sylvania have engineered products that use wireless and energy harvesting sensors, switches and controls.

According to EnOcean, 80% of the companies demonstrating wireless lighting controls at Lightfair were based on the EnOcean Standard and more than 100,000 buildings are benefiting from having the technology installed.

I have to admit I love this technology: The controls regenerate power for radio communications using ambient sources of energy such as light, temperature and motion. And they are interoperable regardless of the manufacturer.

The National Electrical Manufacturers Association (NEMA) has published LL 9-2009 Dimming of T8 Fluorescent Lighting Systems.

This new standard is the first coordinated guidance from industry on the dimming of T8 fluorescent lighting systems; LL 9 covers ranges between 100% and approximately 35% output (60mA lamp current). The publication was a result of discussions between numerous manufacturers and end-users as well as years of data gathering, testing, and analysis.

LL 9 may be downloaded at no charge, or a hardcopy purchased for $36, by visiting
www.nema.org/stds/ll9.cfm, or by contacting IHS at 800-854-7179 (within the U.S.), 303-397-7956
(international), 303-397-2740 (fax), or global.ihs.com.

Building Design & Construction’s July issue features an article by C.C. Sullivan and Barbara Horwitz-Bennett titled, “MEP Technologies for Eco-Effective Buildings,” includes several sections related to lighting. I was pleased to participate in the article as a source instead of an author this time, representing my client the Lighting Controls Association, for which I’m acting education director. It’s a well written story and worth a read.

I got my hands on a very informative graphic from Lutron describing how LED drivers–electronic devices that conditioning incoming power to match the circuit design and configuration of the LED array in the light fixture–interact with the LED lighting system.

Drivers may be integral to power supplies, separate of power supplies but integral to the luminaire, or combined with the power supply within the luminaire. Drivers also provide a control interface for dimming and/or color control. In fact, in simple low-power systems without control functions, the driver may be optional, as shown.

Royal Philips Electronics has announced that it has acquired Teletrol Systems Inc., a supplier of integrated solutions for simultaneous multi-site management of lighting and energy usage. The Teletrol product portfolio will strengthen Philips’ range of sophisticated control solutions for institutional customers, including the networked management of lighting and environment facilities, including heating and air conditioning. Financial details of this agreement were not disclosed.

Founded in 1985, Teletrol, based in Manchester, NH, has built up a significant position with installations in more than 10,000 commercial and retail sites around the world. The company employs 37 employees, and has posted double-digit sales growth in recent years, a performance level which is expected to continue in years to come as it leverages Philips’ existing global distribution channels.

Teletrol’s operations will be incorporated into the Lighting Electronics group of the Philips Lighting sector.

The Lighting Controls Association (LCA) has announced that EE300: Lighting Control of LEDs has been added to the Association’s popular online Education Express distance education courses.

Residing at the Association’s website, www.aboutlightingcontrols.org, Education Express provides in-depth education about lighting controls and controllable ballast technology, application, system design and commissioning, as well as meta-issues such as energy codes, daylighting and other trends.

In recent years, LED technology has transcended its traditional stronghold—saturated colors in indicators, exit signs and so-called architainment applications, representing most LED products sold today—and began offering viable white light options in niche architectural applications such as lighting for outdoor and small, confined indoor spaces.

As the technology continues its steady advance, applications have expanded to downlights, undercabinet, shelf, signage, façade, outdoor area, wall washing, cove, task, refrigerated display case, step/wall, electrical candle, sconce, handrail and marker lighting as well as retrofit replacement lamps.

Just as with conventional lighting systems, a critical consideration in applying LEDs in building environments is control. LED controls be used to create a virtually infinite array of color output, or modulate the warmth or coolness of white light LED sources. They can allow dimming of LED light sources to occupant preference. And they can automatically shut off or dim lighting in response to control signals from inputs such as photosensors, scheduling devices, PCs and others.

EE300: Lighting Control of LEDs, broken into four learning modules, describes the fundamentals of how LEDs work and are controlled (part 1), control of color LEDs (part 2), control of white LEDs (part 3), and typical applications for LED control (part 4). The goal of the course is to provide a working understanding of LEDs and methods for integrating them into modern lighting system design.

At the conclusion of the first three learning modules, an optional online comprehension test is available, with automatic grading; a passing grade enables the student to claim education credit. EE300: Lighting Control of LEDs is registered with the National Council on Quality in the Lighting Professions (NCQLP), which recognizes a total of 6.6 LEUs towards maintenance of Lighting Certified (LC) certification.

Since its launch in June 2006, Education Express has served more than 7,000 students, who have benefited from more than 28,000 completions of course modules and some 11,000 comprehension tests taken online, enabling them to earn education credit.
