Methods and systems for updating an airfield lighting system with an LED light source are described herein. One method includes removing a light source from an existing light fixture of an airfield lighting system, wherein the removed light source is not a light emitting diode (LED) light source, and replacing the removed light source with an LED light source in the existing light fixture without modifying or replacing any other element of the existing light fixture.

Updating an airfield lighting system with an LED light source

The present disclosure provides methods, devices, and computer-readable media for health monitoring of lights. One or more embodiments include receiving data, including a junction temperature of a light emitting diode (LED), an ambient temperature, and a drive current associated with the LED, receiving a pre-existing LED performance data set, and determining an end of life of the LED based on the junction temperature of the LED, the ambient temperature, the drive current associated with the LED, and the pre-existing LED performance data set.

Health monitoring of lights

Precision approach path indicator (PAPI) measurement systems and methods are described herein. One system includes a number of light sensor modules, wherein each light sensor module is configured to determine an intensity of a beam of light from a PAPI unit, a memory, and a processor configured to execute executable instructions stored in the memory to determine a transition angle of the beam of light from the PAPI unit, an elevation angle of the beam of light with respect to horizontal, and a width of a transition region of the beam of light, based, at least in part, on the intensity of the beam of light determined by each light sensor module.
