Dimming Behaviors of LED Replacement Lamps - LRC researchers investigated the dimming performance of commercially
available LED replacement lamps and the performance variations among
different residential dimmers.
Designing a Better Recessed Downlight Using SPE Technology - The LRC developed a highly efficient LED downlight to replace an equivalent 75W incandescent or 26–32W CFL downlight.
Accelerated Life-test Method for LED Drivers - The LRC conducted a study to understand what factors influence the failure modes of standalone LED drivers, and to develop an accelerated test method to predict the useful life of an LED driver.
LED Beacon Lights on Maintenance Trucks are a Safe, Economical Alternative - A recent study by the LRC has shown that LED beacon lights use less power without compromising safety.
Lighting Supermarket Freezers with LEDs - A field study investigating the use of white LED lighting inside supermarket freezers, including energy comparisons with fluorescent, sales analyses, and shopper preferences.
LEDs: Saving Energy in Retail Display Windows - A field study using LEDs as colored background lighting for retail window displays in order to reduce accent lighting power by up to 50%.
Innovative Lighting Solutions for Senior Care Facilities - A demonstration showing how innovative lighting designs and advanced technologies, including LEDs, photosensors and occupancy sensors, can help seniors in long-term care facilities maintain independence and be more comfortable.
Improving White LED Efficiency Through Scattered Photon Extraction (SPETM) - A new method of extracting more light from white LED packages, SPE™ significantly increases the light output and luminous efficacy of white LEDs.
Characterizing the Thermal Resistance Coefficient of LEDs - The accuracy of measuring LED junction temperature—a strong predictor of LED performance—depends upon the value of the LED's thermal resistance coefficient. This study explored how thermal resistance changes with different parameters.
Electronic Walls and Ceilings Offer Adaptable Solid-State Lighting - The LRC and ASSIST are developing a flexible interior infrastructure that will integrate solid-state lighting with other building materials and systems. Such an infrastructure would allow for rapid reconfigurations of built-in lighting, making it as easy to redesign lighting.
