Development of visible and mid Infra-red solid state light emitting diodes to replace inefficient incandescent airfield lighting

LED based lights are becoming desirable as replacements for incandescent lamps in airfield lighting applications, driven by the need for power economy, reliability and legislation. However, Enhanced Flight Vision Systems (EVFS) employ an indium antimonide photodetector, which is sensitive in the range 1.5 to 5 microns and use the mid IR emission from the incandescent lighting. EFVS cannot 'see' visible LED replacements. This project will investigate the fabrication and characterisation of state-of-the-art semiconductor materials and novel LED devices, leading towards further development to achieve the same spectral output characteristics as incandescent lighting.
