The long-term performance of LEDs

Light-emitting diodes (LEDs) have made progress in recent years, providing increased light output, color properties, and energy efficiency. Costs have decreased as a result, while use of LEDs has increased. LED lighting is a practical option for aviation due to the need for colored light and low light output requirements. Airports are increasingly transitioning to LED systems. However, since LED luminaires are new to the market, there have been no sufficient tests of long-term performance. The useful life of the LED and the luminaire depends on system integrations and the conditions in which the fixture is used. Environment and on-off cycling patterns could have an impact on the expected life of the luminaire. There has been some research into the useful life of LEDs, but more work on the long-term performance of LED airfield luminaires is necessary.
