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. 

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. 

LD+A Research Matters: Super Lamp Initiative

03/01/2010

LD+A – The strategy is to foster the development of high-efficacy light sources that achieve, as much as possible, interchangeability with incandescent lighting, in terms of compatibility with electrical infrastructure and with popular lighting expectations. This article is a summary of CLTC research aimed at developing a technology-neutral Super Lamp specification for replacement of incandescent sources in the residential sector.

Bi-level Switching in Office Spaces Project Report

02/01/2010

The primary objective of this study is to quantify the energy use in private offices that are equipped with bi-level switching and occupant controls. The baseline comparison is made to a theoretical case where the occupant has no control over their lighting and it is switched on and off solely by an occupancy sensor. In addition, this study looks closely at the possibilities for combining automatic and manual control to achieve the greatest energy savings and user satisfaction.
