Understanding Flicker in Airfield Lighting Applications

Nearly all electric light sources produce flicker, especially when operated from mains power. Light-emitting diodes (LEDs) can use a wide variety of driving methods, including constant direct current, pulse width modulation, or from mains power using simple rectifiers, each resulting in different amounts of perceived flicker. Quantifying the effects of flicker from light sources is important in specifying light source performance in many lighting applications, including airfield lighting. With funding from the Federal Aviation Administration (FAA) and from the Alliance for Solid State Illumination Systems and Technologies (ASSIST), researchers at the Lighting Research Center (LRC) conducted a series of studies to develop a model to predict the detection and acceptability of stroboscopic effects from light source flicker. Further studies looked at new and efficient electrical LED circuit designs to produce light output waveforms with reduced perception of stroboscopic effects. The present paper summarizes these efforts.
