LD+A Research Matters: Smart & Clean Exterior Lighting for the Community

Researchers at the California Lighting Technology Center are addressing the integration and demonstration of exterior lighting systems with on-board solar generation, battery storage and advanced controls with funding provided by the California Energy Commission’s EPIC program. In other words, “smart and clean” exterior lighting systems.

LD+A Research Matters: Residential Energy & Automation Systems

The California Lighting Technology Center is excited to kick off research into today's Residential Energy & Automation (REA) Systems in collaboration with California's statewide electric emerging technologies program, CalNEXT.

REA systems combine home-energy monitoring features with automated appliance management and control of distributed energy resources (DER) such as electric vehicle (EV) chargers, rooftop solar panels, and stationary battery energy storage (BES).

LD+A Research Matters: Performance Evaluation of a Solar Tracking Lighting System

CLTC recently partnered with the California Energy Commission, Sonoma Clean Power Authority, and Frontier Energy Inc. to evaluate opportunities in emerging daylighting technologies. One such technology is a solar-tracking lighting system, which delivers daylight via optical fibers to core building areas that otherwise do not have access to daylight.

LD+A Research Matters: Integral Metering & Reporting Capabilities of Networked Lighting Controls

Networked lighting control (NLC) systems have proven they can successfully reduce demand and save energy in real-world applications through a combination of basic and advanced control strategies. However, the potential of NLCs’ integral metering and reporting capabilities to provide cost effective energy-use data for incentive programs and outcome-based code opportunities has not been fully realized. This is, in part, due to the variety of metering and reporting approaches used by today’s NLCs.

LD+A: Faces of the Future


In 2010, LD+A compiled their list of “Future Leaders”.  LD+A editors reached out to more than 50 lighting professionals representing all corners of the industry and asked that they submit nominations. LD+A also contacted IES leadership at the Section level, as well as IES members involved in both the IES Emerging Professionals and Young Professionals Scholarship programs, for their feedback.  LD+A asked each of these people to recommend those with approximately five years experience who are on the cusp of leadership positions (e.g., technical, management, educational) in the industry. 

IES LD+A Research Matters: Smart Corridors Light the Way to Energy Efficiency


If a light dims down to the minimum recommended illumination level in a secondary space and no one is around to see it, does it really make a difference? Research shows yes—it makes a big difference in reducing lighting energy use.

Laboratory and field testing of prototype systems that dim corridor lights down to 50% or less of full output during vacancy periods and increase to full output during occupancy show significant reduction in lighting energy use and great potential for effective electricity demand response.

LD+A Research Matters: A New R&D Center for Mexico's Lighting Industry


In the fall of 2017, the Mexican Ministry of Energy awarded funding to the Universidad Autónoma de Guadalajara in collaboration with the University of California Davis to establish a lighting technology and design research center known as the Centro de Tecnología en Iluminación (CTI). This is a multi-year, public-private investment focused on addressing growing climate change concerns through translational research committed to clean energy and sustainability in Mexico.
