Given current adoption of commercial building energy codes, conventional wisdom indicates that LED lighting is frequently specified with automatic lighting controls. However, there is little public data available concerning market penetration of LED lighting, how often it is specified as controllable and with lighting controls, owner preferences, and how satisfied specifiers and installers are with […]
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 […]
Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, U.S. Department of Energy Solid-state lighting has proven that it can deliver high-quality light with substantial energy savings in many applications. But dimming can still be an issue, as CALiPER testing and GATEWAY demonstrations have shown. This concern was […]
The National Electrical Manufacturers Association (NEMA) has published NEMA LSD 56 Compatibility of Forward Phase Control Dimmers and Dimmable Self-Ballasted Compact Fluorescent Lamps and Frequently Asked Questions Regarding CFLs and Dimming, available for free download. This publication provides design guidance in the area of lamp/dimmer compatibility to the manufacturers of dimmable self-ballasted compact fluorescent lamps […]
The Lighting Controls Association is pleased to announce that it has updated EE103: Dimming Control, a popular offering in the Association’s Education Express series of online distance education courses about lighting controls. The course, authored by Craig DiLouie, principal of ZING Communications, Inc. and LCA’s Education Director, provides an in-depth discussion of dimming technology and […]
Plasma lighting is a new generation of efficient lighting suitable for high-intensity applications such as parking lot, high-bay warehouse, streetlights, billboard and garage applications. The basic technology consists of a driver that emits radio waves to create an electric field around the source, which converts its contents into a plasma state that generates intense white light. The result is a light source about the size of a tic-tac that produces up to 23,000 initial lumens.
Craig DiLouie of the Lighting Controls Association recently talked to Randy Reid, VP marketing for Luxim, about the control aspects of this interesting and novel lighting technology. Click the below link to see the interview.
The Lighting Controls Association is pleased to announce that it has updated EE103: Fluorescent Dimming, a popular offering in the Association’s Education Express series of online distance education courses about lighting controls. The new course, authored by Craig DiLouie, principal of ZING Communications, Inc. and LCA’s Education Director, is divided into two sections: Dimming Control, and Fluorescent Dimming Ballasts. The first section, Dimming Control, provides an in-depth introduction to dimming, including popular dimming strategies, methods, controls, human perception and response, and how different light sources behave while dimmed. The second section, Fluorescent Dimming Ballasts, covers technology and application issues such as dimming methods and lamp-ballast interactions.
“If you boost the lighting at certain times of day, you’ll get a better performance from workers,” remarks Dr Martine Knoop, a senior lighting specialist at Philips Lighting, commenting on the study that took place at Bartenbach Lichtlabor in Austria. The scientists found in 2007 that if offices used more adjustable lighting, the employees working within them would work more productively.
The National Electrical Manufacturers Association (NEMA) has published two new solid state lighting standards: 1) NEMA SSL 1-2010 Electronic Drivers for LED Devices, Arrays, or Systems, and 2) NEMA SSL 6-2010 Solid State Lighting for Incandescent Replacement—Dimming.
With these publications, NEMA establishes harmonized requirements and expectations for solid state lighting (SSL). Both are directed toward designers, manufacturers, and users of SSL products.
This document provides general information and considerations involved in the design and application of dimming circuitry employed with specific ballasts and lamps in the HID family. Click here to download it free from the NEMA website.
