Adaptive Corridors at UC Davis

07/01/2011

A basic adaptive lighting system is composed of occupancy sensors, dimmable ballasts and sources, and a communication platform for the system components. By combining commercially-available components, multiple solutions may be implemented to deliver occupancy-based, adaptive corridor lighting. Three of these solutions were demonstrated and evaluated in corridor applications in a multi-use building at the University of California, Davis. 

Integrated Office Lighting System at the Department of Motor Vehicles in Sacramento, CA

05/01/2010

The Department of Motor Vehicles (DMV) implemented the IOLS in a planned multiyear renovation of its 520,000-square-foot headquarters in Sacramento, CA. The original lighting goal was to provide more uniform task lighting and higher visual comfort. Original designs fell short of these goals. The IOLS, in contrast, met design objectives and increased energy savings. 

Advanced LED Downlights

05/01/2010

Lighting California's Future – The Advanced LED Downlights project takes downlights in a whole new direction—up! The LCF project partners developed a dimmable downlighting system based on indirect optical design that reduces glare, decreases installation time, averages LED color variations and improves thermal management. 

Bi-level Street and Parking Area Luminaires at Cal Poly San Luis Obispo

05/01/2010

PIER-sponsored research, development, and demonstration has focused on the combination of occupancy-based lighting controls and broad-spectrum light sources to create intelligent, bi-level luminaires designed for street and parking area applications. These products achieve 30 – 75% energy savings compared to traditional street and area luminaires, meet stringent energy-efficiency standards, and provide excellent light distribution for reduced night sky pollution. 

Adaptive LED Parking Garage Luminaires

04/01/2012

California's Public Interest Energy Research (PIER) program sponsored the development of adaptive parking garage luminaires that integrate intelligent controls with adaptive electronic drivers or ballasts to control light output based on garage occupancy. CLTC partnered with PIER on three demonstrations of the technology in parking garages at CSU Sacramento, CSU Long Beach and the San Marcos Civic Center Parking Garage. Luminaires operate at a reduced power during vacancy and switch to full output when occupants approach the area.

GE 9-watt Bulb is First A-Line LED Lamp to Earn ENERGY STAR Rating

12/07/2010

Business Wire – The team of GE scientists, engineers and product managers responsible for development of the company’s first general service household LED bulb—a 9-watt GE Energy Smart LED bulb with a unique omni-directional light output meant to replace a 40-watt incandescent bulb in desk, bedside or hallway lamps—celebrated the bulb’s designation as the first standard incandescent shaped (A-line) LED bulb to earn an ENERGY STAR rating.

UC Davis Smart Lighting Initiative

UC Davis Smart Lighting Initiative

The UC Davis Smart Lighting Initiative was established in 2010 to improve the quality and efficiency of both indoor and outdoor lighting on campus. The initiative's primary goal is to reduce UC Davis's electricity use for lighting by 60 percent, based on 2007 levels of energy use. The effort was inspired by the California Public Utilities Commission (CPUC) and its call to reduce statewide electricity consumption for lighting by 60 percent or more by 2020.

LD+A Research Matters: Relamping Retail

04/01/2013

LD+A – As retail stores make efforts to improve their sustainability and energy efficiency, a growing number are considering making the switch to directional LED replacement lamps. Compared to traditional halogen or incandescent sources, LED alternatives are about 75 percent more energy efficient, on average, and they last up to 25 times longer, but efficiency and long life are not enough. 

LD+A Research Matters: From Walls to Walkways

11/01/2012

LD+A – The University of California, Davis, unveiled one of the most advanced outdoor lighting systems in the country this past June. Dubbed the Adaptive Campus Control System, it integrates over 1,600 individually addressed, dimmable LED luminaires with various applications – streetlights, wall packs, area lights, and post tops – into an advanced, wireless lighting controls network.
