Daylight Zones: Toplighted Spaces
Last month at LightingControlsAssociation.org, we published an article about how to establish daylight zones in sidelighted (windowed) building spaces. We looked at an industry rule of thumb and then how the latest generation of energy codes and standards address it. In review, when designing an energy-saving daylight harvesting control system, a critical decision is to […]
Daylight Zones: Sidelighted Spaces
When designing an energy-saving daylight harvesting control system, a critical decision is to establish lighting control zones, identifying lighting loads to be separately controlled. Before this decision can be made, however, we must first determine the daylight zones. A daylight zone, also called the daylight area (expressed in square feet), is defined by the ASHRAE/IES […]
Control Design Toolbox: The Lighting Controls Narrative
As demand for lighting controls continues to grow, advanced solutions are becoming increasingly specified while also becoming increasingly sophisticated. This increasing sophistication translates to greater owner benefit but can also pose greater risk of design and installation mistakes. In a perfect world, designers create clear and detailed lighting control requirements that are easily installed by […]
Controlling Plasma Lighting: A Short Conversation With Randy Reid Of LUXIM
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.
Lighting Controls Association Updates Education Express Course on Fluorescent Dimming
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.
HID Lamp Dimming
Dimming is growing in popularity due to energy codes, green construction and user interest in flexibility and maximizing energy savings. High-intensity discharge (HID) lamp dimming is no exception, and with continuing development of electronic HID ballasts, continuous HID lamp dimming is easier to achieve, in a broader range of wattages, than ever before. This whitepaper by the Lighting Controls Association describes dimming options for popular HID lamp types and presents NEMA guidelines for dimming HID lamps.
More Than 80 Percent Of Electrical Contractors Work With Lighting Controls
ELECTRICAL CONTRACTOR recently published a very informative article detailing the results of a survey of more than 700 readers about lighting and lighting controls, conducted by Renaissance Research & Consulting.
LEDs Magazine Publishes Article About Dimming LED Lighting
LEDs Magazine has published an article by David Cooper about dimming LED lighting. Get the full story here.
Energy Standards Take On Daylight Harvesting
Because of the strong energy savings potential offered by daylight harvesting, coupled with advancing technology, codes and standards are now beginning to address daylight harvesting—specifically, International Energy Conservation Code (IECC) 2009, ASHRAE/IES 90.1-2010, ASHRAE 189.1 and Title 24-2008.
