This paper reviews the key market and technology drivers associated with the emerging application of light-emitting diode (LED) technology in the lighting of buildings. The paper focused primarily on the evolving marketplace, the technology, and how current market and regulatory pressures will form the key drivers for near-term and long-term market penetration for emerging light sources.
This year, 2014, marks the 10th Annual Luminaire Design Competition for students enrolled in Designing with Light (DES 136 B) at the University of California, Davis. The competition gives students the opportunity to work with state-of-the-art lighting technologies and to share their designs with professionals in the lighting industry. Seoul Semiconductor and LEDLab supported the 2014 competition and provided each student with an Acrich2 LED module for use in their energy-efficient outdoor luminaire prototypes.
Linear fluorescent lamps account for 83 percent of installed lamps in the California commercial sector per a lighting market characterization performed in 2014. LED lighting products are receiving attention for their potential to replace fluorescent lighting, reduce energy use and improve lighting quality in a variety of indoor commercial applications, including offices, classrooms and retail stores. LED alternatives to linear fluorescent lighting products fall into three main categories: linear retrofit lamp solutions, linear retrofits for troffers and dedicated luminaires.
CLTC Co-director Konstantinos Papamichael will present at this year's Strategies in Light event in Santa Clara, California. Dr. Papamichael will speak from 2:30 to 3 p.m. Wednesday, February 26 on issues related to LED lighting and luminous comfort, well-being, and aesthetics.
This working paper, co-written by CLTC Directors Michael Siminovitch and Konstantinos Papamichael, urges manufacturers, regulators and utilities that offer product incentives to consider quality and consumer satisfaction first when it comes to LED products. Their arguments in favor of lighting quality, over efficiency, were also presented in "Trading Up," an article published in the August 2011 issue of LD+A.
Working in partnership with California's energy stakeholders, CLTC has created a third-party LED lamp testing program and a database for test results. The LED Performance Database is designed to help utilities and other organizations understand how the LED lamp market is evolving and identify which lamps meet the Voluntary California Quality LED Lamp Specification.
Jade Sky Technologies – Jade Sky Technologies (JST), a clean-tech start-up manufacturer of driver ICs for LED lighting applications, announces its affiliate partnership with the California Lighting Technology Center (CLTC). The aim of the partnership is to demonstrate the technical and economic feasibility of meeting the best-in-class standards set by the California Quality LED Lamp Specification, which is set to take effect in January 2014.
Rambus Inc. – Rambus Inc. (NASDAQ: RMBS), the innovative technology solutions company that brings invention to market, today announced it is now an affiliate of the California Lighting Technology Center (CLTC) at the University of California, Davis.
LD+A – CLTC researchers incorporated passive infrared (PIR) occupancy sensors and networked controls into a test set of dimmable LED roadway fixtures. The adaptive street lighting system yielded energy savings 27 to 42 percent greater than when the fixtures operated at a static level. All occupants, 100 percent, were detected by the PIR occupancy sensor selected for field testing, whether they were traveling on foot, by bicycle, on a motorcycle, or in an automobile.
