A new exploratory study conducted in the Department of Energy’s Connected Lighting Test Bed investigates energy losses in Ethernet cables used between PoE switches and luminaires in PoE connected lighting systems.
Department of Energy Launches Connected Lighting Testbed
To accelerate advances in connected lighting systems, DOE developed a connected lighting test bed (CLTB) in 2016 to characterize the capabilities of market-available connected lighting systems. The results will increase visibility on what does and does not work, and create tight information feedback loops to inform technology developers about needed improvements related to interoperability, configuration […]
Lighting Research Center Expands SSL Research Capabilities to Connected Lighting
In a 25,000-square-foot commercial office on the Rensselaer Technology Park campus in Troy, N.Y., scientists from the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute are making plans to install LED lighting with fixture-integrated and network-connected lighting controls. The controls are being tested in a broad-based field evaluation to compare and quantify the additional benefits […]
Defining Accuracy: Energy Use Reporting through Lighting Control Systems
One of the features of networked lighting controls is the ability to monitor lighting energy use over time and adjust the system to achieve the best possible performance. Recent work by the California Lighting Technology Center with Sempra Utilities showcases the development of a test methodology to evaluate the accuracy and reliability of onboard metering […]
VTTI Tests On-Demand Roadway Lighting
Vehicles are expected to play a big part in the Internet of Things. By 2020, 250 million connected vehicles will be on the road, creating new services and driving capabilities, according to Gartner, Inc. Infotainment is high in demand, though other capabilities are enabled, including crash warning, traffic violation warning and relaying weather, traffic and […]
Saving Energy in Buildings with Adaptive Lighting Systems: Solutions for the Retail Sector
The California Lighting Technology Center has produced a new report covering the current state of retail lighting and the extraordinary energy savings potential that can be achieved with adaptable lighting control systems. From CLTC: “To address the slow adoption of adaptive lighting solutions in the retail sector, researchers developed and demonstrated an optimized retail lighting […]
DOE Profiles Commercial Building Stock
The U.S. Department of Energy (DOE) has begun releasing results from the 2012 Commercial Buildings Energy Consumption Survey (CBECS). The CBECS is an estimated profile of the U.S. commercial building stock based on an interviewed sampling. Information includes number of buildings, floorspace, age, building type, region, energy consumption, end-use equipment and more. DOE defines a […]
DOE’s Public Street and Area Lighting Inventory Survey Suggests Future Growth in Adoption of Advanced Lighting Controls
DOE’s Municipal Solid-State Street Lighting Consortium (MSSLC) has released the results of a voluntary web-based inventory survey of public street and area lighting across the U.S., conducted during the latter half of 2013 and intended to improve understanding of the role of public outdoor lighting in national energy use. Results were based on the responses […]
Market Research Suggests High Degree of Confidence with LED Lighting and Controls
Given current adoption of commercial building energy codes, conventional wisdom indicates that LED lighting is frequently specified with automatic lighting controls. However, there is little public data available concerning market penetration of LED lighting, how often it is specified as controllable and with lighting controls, owner preferences, and how satisfied specifiers and installers are with […]
DOE Publishes CALiPER Report on Dimming, Flicker and Power Quality Characteristics of LED PAR38 Lamps
The U.S. Department of Energy’s CALiPER program has released Report 20.2, which is part of a series of investigations on LED PAR38 lamps. Report 20.2 focuses on dimming, flicker and power quality characteristics evaluated with a single dimmer. The dimming, flicker and power quality behavior of the LED PAR38 lamps evaluated in this study was […]
