Demonstration of Solid-State Lighting Technologies and Design Metrics(20349)

Rensselaer Polytechnic Institute


Solid-state lighting has the potential to revolutionize the market for lighting products. The light-emitting diode (LED), one of the most promising solid-state lighting technologies, has several unique properties that make it an ideal source for several lighting applications. The U.S. Department of Energy target for white LED light sources is 150 lm/W by the year 2012. Compare this with the incandescent lamp at 14–20 lm/W, which remains the most prevalent light source in use today, and it is clear that solid-state lighting has the potential to reduce lighting-energy use in many applications by as much as 90%. LEDs have the potential to last over 50,000 hours and are also easily dimmable and tunable. Another advantage of solid-state light sources is that, unlike traditional light sources, they radiate little or no heat, infrared or ultraviolet radiation. Finally, solid-state light sources contain no mercury or other known harmful compounds, making them an environmentally-friendly and sustainable lighting technology. However, because LEDs are still a new and rapidly advancing technology, careful steps must be taken to ensure that end users and lighting specifiers, as well as lighting system and luminaire developers, in New York State, have the information they need to make informed decisions about how to select, apply and develop this technology effectively.

Project Description

The project will establish a position on the ASSIST advisory board for NYSERDA; develop new research methods and metrics for evaluating LED systems; and demonstrate promising LED products on site in New York State. It will also evaluate the products using the new metrics and publish the results in a Demonstration and Evaluation of Lighting Technologies and Applications (DELTA) report, as well as identify applications where it makes sense to use LEDs and develop LED application guidelines. Finally, it will educate and inform New York's manufacturers and ratepayers of the outcome, by offering four LED Lighting Institute 3-day seminars over the two-year project.


The ASSIST program develops and initiates research of common interest to its commercial and government partners. Developing standardized LED test procedures and guidelines for LED applications will provide end users and manufacturers with a common set of metrics to evaluate their installations and products, and will help manage the public’s expectations of LEDs’ performance. Providing this information to the public will help the LED technology phase into installations and applications where the technology offers clear advantages.
