5. 3 © 2013 Eaton, All Rights Reserved. LED Technology Solid-state lighting (SSL) technology has the potential to reduce lighting energy usage by over 90% and contribute significantly to climate change solutions. For the past decade, airfield lighting manufacturers have launched several LED based products that brought a mere 60% energy savings for airfield applications. What is missing?

6. 4 © 2013 Eaton, All Rights Reserved. Evolution of LEDs in Airfield Lighting Began with Taxiway elevated edge light products over 10 year ago Fixtures installed in existing 5kV airfield lighting environment use a microprocessor based power supply to meet dimming requirements Today LED products are available for Taxiway, Runway, Approach and Navigational Aids and Guidance signs

7. 5 © 2013 Eaton, All Rights Reserved. Issues resulting from LED use in airfields Current 6.6 A Series Airfield Lighting System added complexity and cost to the LED fixture due to the addition of electronics to mimic the non-linear dimming curve of incandescent lighting. LEDs must convert the supplied AC current to a modulated DC. Active electronic elements within each fixture may introduce high levels of total harmonic distortion or other electrical quality issues which are largely unregulated.
