Abstract

The Medium Intensity Approach Lighting System (MALSR) in use today at many airports throughout the United States employs many incandescent spot lamps. These lamps are relatively high wattage and, because of their relatively short life, require continual maintenance. Light emitting diodes (LEDs) have matured to the point that they can be considered to replace the inefficient incandescent lamps, especially when the latter are used with color filters. Under a Federal Aviation Administration (FAA) contract, Lighting Innovations Corporation (LIC) has developed LED based green runway threshold lamps for use in the MALSR. They already have been tested under flight conditions and are scheduled for full operational testing at several airports throughout the country. This paper addresses the advantages of LEDs over incandescents in this and other airfield lighting applications. Photometric, radiometric and spectral quantities are discussed, as are electrical, thermal and mechanical aspects of the project.
