Bringing Advanced, Energy-Efficient LED Lighting to Aviation
Advanced, energy-efficient lighting is one strategy at the forefront of 21st century global research to reduce energy use and carbon emissions. Light-emitting diodes (LEDs), a type of solid-state lighting, can benefit the aviation industry and U.S. airfields significantly. LEDs promise lower energy consumption, reduced maintenance, and better visual perception for pilots.
Yet implementing LEDs is not as simple as unscrewing one light bulb and replacing it with another. LEDs are an inherently different light source than traditional incandescent lamps, requiring a complex understanding of their benefits, drawbacks, perception differences, and how they can be best integrated into lighting systems.
Since 2005, the LRC has been assisting the Federal Aviation Administration (FAA) and its research divisions through synergistic activities that combine the LRC's expertise in lighting technologies, applications and human factors research. The LRC conducts lighting research as part of the Center of Excellence for Airport Technology, applying its expertise in the areas of solid-state lighting and vision science to provide new lighting solutions that benefit the aviation industry.
As part of the Center of Excellence, the LRC studies the potential performance and application of LEDs in airport and airfield lighting. The LRC looks at how this new technology can be applied to light runways, taxiways, approaches, and other areas of the airfield. To date, the LRC has investigated:
The LRC is using these investigations as the basis to help the FAA create and amend performance metrics and requirements that are appropriate for LED airfield lighting.
