New and Underutilized Technology: Interior LED/Solid State Lighting

Per the US Department of Energy:

 

Application

Interior LED/solid state lighting is a rapidly improving technology currently most applicable for down lights, track lights, task lighting, accenting, high ceiling, and high cost maintenance areas.

Key Factors for Deployment

Prior to deployment, evaluate sample LED products in their intended fixtures and applications to gauge appropriate fit – both physically within the fixture and lighting quality and aesthetic requirements.
Also evaluate test data to verify product performance is based on standardized photometric testing (e.g., IES Method LM-79-08) and not LED chip performance alone. Performance and life of the LED replacement lamps is highly dependent on their design and thermal management, which includes the fixture in with they are installed. The product should be covered by a warranty or return policy in case the lamp does not perform as claimed.
Examine ways to incorporate solid state lighting into lighting retrofit strategies, such as low ambient/task lighting.

Ranking Criteria

Federal energy savings, cost-effectiveness, and probability of success are ranked 0-5 with 0 representing the lowest ranking and 5 representing the highest ranking. The weighted score is ranked 0-100 with 0 representing the lowest ranking and 100 representing the highest ranking.

Lumewave, Wireless Lighting Control

Wireless Street Lighting Controls

Lumewave's wireless, remote control and monitoring of street lights can save energy, enhance public safety, reduce light pollution, reduce maintenance costs, provide valuable M&V information, and fixture health reporting to municipalities, states and other users. They can be used with LED, Induction, Plasma, eHID lighting, and standard HID. However, because of certain limitations with older HID technology, Lumewave can still be used with those systems, but much functionality is lost.

A centralized command system can send astronomic time based instructions to individual or groups of street lighting to reduce energy consumption, when and where possible, during night time hours.

Demand responsive and adaptive, lighting can be dropped to lower levels through user selected, multi-level dimming scenarios, or based on input from traffic monitors or other systems and sensors.  Revenue grade power metering through the use of Smart Meter chips is standard.

Signaling for location identification of Call Button activation or 911 calls, designating evacuation routes, detours and other emergency uses are standard capabilities with Lumewave controls.

Additional public safety uses can include the ability for police or other emergency vehicles to interface through their onboard computers and raise light levels from nearby streetlights even higher than normal to aid in visibility for investigation, medical administration and incident clean up.
Lumewave's Gateway and software allow users to communicate with over a million system devices if a customer's network was that large. Standard units provide a 5 mile range to devices when mounted on poles twenty feet or higher.

Lighting Case Study, Mayo Clinic

When the Mayo Clinic broke ground on the $441 million Gonda Building, design manager Stan Larson said every purchase was carefully reviewed to ensure it would deliver long-term value.  “With the pressure of construction costs, we needed to deliver good quality within budget,” he said. Because Larson had successfully used a variety of Williams Downlighting products in past Mayo remodeling projects, he knew the company could meet the high standards required in a new world-class medical complex. “With some of our key lighting applications, we chose Williams Downlighting because they consistently deliver high performance at a competitive price.”

While Williams Downlighting was widely used in conference rooms, offices and hallways, a critical application was illuminating employee cafeteria and break room areas. As part of the open foyer design, the project called for colored-glass downlights in these locations that would be visible from the building’s main atrium. Though Williams Downlighting offered four standard colored-glass options for its recessed fluorescent fixtures, the company successfully delivered a broader palette of custom colors required by the Gonda project.  “This application had some really precise needs,” said Rob Chasse of JTH Lighting in Eagan, MN, who partnered with Larson on the project. “Williams Downlighting collaborated with its glass suppliers to make sure the final product was what the architect and lighting designers wanted.”

Mayo’s attention to detail has paid handsome dividends. The 20-story Gonda Building has received several architectural awards – including honors from the International Interior Design Association for excellence in interior lighting.  “The workmanship on the Williams Downlighting fixtures always seems to be higher than some of the other manufacturers that just stamp them out,” Larson said. “When I first saw their factory, I was impressed with their design ideas, manufacturing processes, and work ethic. Time and time again, that shows in the results we get in working with them.”
