Strategic Telemetry and XUS Corp.'s Adaptive LED Streetlight Systems Save Energy



Strategic Telemetry and XUS Corporation reportedly announced the first “Electrical Lighting and Management System” to offer light control methods for LED street lighting that conforms to the “Intelligent Transportation Systems” standard of the National Transportation Communications for ITS Protocol 1213.

Additionally, this EMS offers dynamic remote control and monitoring of lighting, power metering and ground-fault detection safety equipment.


“Roadway lighting designers typically select components that deliver the required minimum level of light at the fixture’s end of life,” said Jim Frazer, COO of Strategic Telemetry.” As light output degrades significantly over the fixture’s life, up to 30 percent of this light output and resultant energy use is simply not required. Using Strategic Telemetry’s adaptive lighting system with dimmable XUS fixtures, light output can be reduced at time of installation, and increased automatically as the fixture ages. Using this technology allows luminaries to emit a constant amount of light, meeting the required levels over the entire installed life of the fixture, without over lighting or excessive energy usage.”


The single significant driving force for such a technology is to have greener and lower power consuming display systems to minimize the gradual, but sure, dismantling of the Earth’s environment due to nature destroying emissions from electric power generation plants. Support of ITS standards, helping in energy saving and providing “Smart Grid” solutions assure that these installations are eligible for state and federal infrastructure funding.


A recent report claimed that American Reinvestment and Recovery Act of 2009 has allotted $11 billion, of the total $63 billion towards energy, for smart grid initiatives through 2010, and that public, private and consumer factors are all driving this growth.


The DOE reportedly plans to distribute $3.9 billion in Recovery Act funds for smart grid projects through two funding opportunities. The first provides $3.3 billion to deploy and implement smart grid technologies across the country, and the second provides $615 million for smart grid demonstration projects. 

Other funding and categories within ARRA this new combined technology probably qualifies for are: $6.3 billion for state and local governments to make investments in energy efficiency; $2.5 billion for energy efficiency research; $3.2 billion toward “Energy Efficiency and Conservation Block” grants; and $250 million to increase energy efficiency in low-income housing.


A “Smart Grid” has Internet connectivity so that signals can be sent and received for each and every connected and authorized device. For example, in this case, smart meters. In a broader sense, the Smart Grid concept creators envisaged that the entire grid would work more efficiently, accommodate wind and solar power, possibly lower electricity bills by optimizing electricity flow, and constantly reduce the carbon footprint.


“By providing ‘fixture-ready intelligence,’ and dimming using either a centralized control communication interface or independent fixture control, this product provides extended lifetime expectancy, and optimum light output,” said Bob Gray, chief executive officer of XUS Corporation. “Together with Strategic Telemetry, the ‘XDRIVE’ roadway light provides a seamless interface with ITS compliant software. The integrity of the communication link is solidified by using Echelon Corporation’s LonWorks network control technologies. Compliance with ITS standards allows data backhaul over the nation’s ITS network and enables control, monitoring and diagnostics previously unimaginable to the street and roadway lighting marketplace.”
