Lighting Education Online is here!

Lighting Education Online is a comprehensive, interactive, Internet-based education program for building, design, and facility management professionals who want to learn more about light and lighting. Lighting Education Online is the first and only university-based lighting education system in which courses are completed entirely over the Internet. There are no additional books to purchase or assignments to complete and mail in. Participants learn online at their convenience. As part of Rensselaer Polytechnic Institute, an accredited university, the LRC will track participants' progress through the program and will award continuing education credits (CEUs) and a certificate for each course completed successfully. These CEUs will also accumulate toward a Continuing Education Certificate in lighting.

ASSIST Program advances solid-state lighting

The Alliance for Solid-State Illumination Systems and Technologies (ASSIST) facilitates broad adoption of LED technology by original equipment manufacturers (OEMs) and specifiers by helping to reduce major technical hurdles and identifying key applications for solid-state lighting technologies. ASSIST is accomplishing this goal through a collaborative partnership between leading LED manufacturers and the Lighting Research Center (LRC). LRC researchers are among the world's foremost experts in solid-state lighting. At our solid-state lighting Web site you can find research, resources, educational opportunities, and links about LEDs and other solid-state lighting technologies.

LED traffic signals promise to save energy and $$$

Traffic signals that use light-emitting diodes (LEDs) offer municipalities and highway authorities significant energy-saving and economic opportunities. The LRC is working with the New York State Energy Research and Development Authority (NYSERDA), the ACEEE, and ICF, to increase awareness and build demand for LED products in New York State. This effort is part of the LRC's Lighting Transformations Program. Read new case studies and examine the LED Traffic Signal Life Cycle Cost Analyzer.

Do high-intensity discharge headlamps cause glare?

LRC scientists are helping the National Highway Traffic Safety Administration (NHTSA) to weigh the relative benefits and potential obstacles facing high-intensity discharge (HID) headlamps, which are being used increasingly on vehicles in the U.S. Recent studies sponsored by Philips Automotive Lighting have shown that HID headlamps improve detection of peripheral objects over halogen headlamps. A thesis study completed by LRC graduate Zengwei Fu, under the direction of John Van Derlofske, LRC Transportation Group leader, indicated that oncoming headlamps with more short-wavelength ("blue") content increase discomfort over lamps with less blue content, but that the increase in discomfort does not necessarily translate into a decrease in visibility. Through additional field studies commissioned by NHTSA, the LRC is well positioned to provide NHTSA with the information it needs as it considers what regulations, if any, will be needed for these new lamp technologies.

Latest lighting application case studies available online

DELTA (Demonstration and Evaluation of Lighting Technologies and Applications) is a program for designing, evaluating, and publicizing energy-efficient lighting solutions. The latest case studies, listed below, are all available free in Adobe PDF format. Download them at the DELTA publications page. You will also find many other DELTA publications that examine lighting in commercial, retail, institutional, industrial, residential, and outdoor settings. High quality, full color, printed publications may be purchased as well. NOTE: New York State residents may order single copies at no cost, thanks to sponsorship by the New York State Energy Research and Development Authority (NYSERDA).

  • DELTA Portfolio: Clifton Park Rest Area evaluates exterior and interior lighting at a newly expanded rest area in upstate New York.
  • DELTA Portfolio: Saratoga Medical Associates evaluates lighting in a suite of medical offices, including the reception and waiting area, nurses' station, examination rooms, and doctors' offices.
  • DELTA Portfolio: Ballston Spa High School evaluates lighting systems for three types of spaces in a high school: the cafeteria, the library, and art rooms.
  • DELTA Portfolio: Hudson Valley Community College evaluates a lighting scheme for computer classrooms with two different arrangements of computers: terminals arranged in rows and terminals arranged around the room's perimeter.
  • DELTA Snapshot: Multimedia Auditorium evaluates two lighting strategies for multimedia auditoriums that support activities in schools and other venues.
  • DELTA Snapshot: Outdoor Entry Lighting shows how changes to the outdoor entry lighting improved the appearance and security of a row house in a historic neighborhood in Albany, New York.
  • DELTA Snapshot: Retail Lighting shows how one retail store–an upscale chocolate shop–uses lighting to attract attention while being energy–efficient.
  • DELTA Snapshot: Gas Station Canopy Lighting compares two types of canopy lighting systems and shows how lighting can attract customers while minimizing light pollution and light trespass.

Diversity Scholarship available

With assistance from a grant from the GE Fund and GE Lighting, the LRC is working to increase participation by students from underrepresented populations within the United States. The LRC is actively recruiting students from all backgrounds and ethnicities. Because LRC graduates often become future lighting leaders, ensuring diversity within the LRC helps to increase diversity in the lighting industry.

Helping older adults live independently

The LRC developed Lighting the Way: A Key to Independence, a series of three booklets that show how effective lighting can increase independence for older adults. The AARP ANDRUS Foundation funded this important project that resulted in booklets, available free in PDF format, aimed at helping specific audiences: older adults, their families, and other caregivers; architects, designers, and contractors; and healthcare professionals.

Resource Collection

The LRC Resource Collection is one of the largest library collections of lighting information in the United States. It has a unique multidisciplinary focus, encompassing all aspects of lighting: architecture, design, energy-efficiency, engineering, human factors, optics, physics, psychology, and vision. You can find research papers, reports, articles, manufacturer information, and more.

About the LRC

The Lighting Research Center (LRC) is part of Rensselaer Polytechnic Institute and is the leading university-based research center devoted to lighting. Founded in 1988, the Lighting Research Center has built an international reputation as a trusted and reliable source for objective information about lighting technologies, applications, and products. Its mission is to advance the effective use of light and create a positive legacy of change for society and the environment.
