Abstract: A landing marker area light system includes a housing, a first light source, a plurality of second light sources, an optics assembly, a tunable lens, and a controller. The first light source emits a first light beam. The second light sources surround the first light source and each emits a second light beam. The optics assembly receives the first light beam and shapes the first light beam into a first geometric-shaped light beam having a first perimeter. The tunable lens receives the first geometric-shaped light beam and, in response to lens control signals, shapes the first geometric-shaped light beam into a second geometric-shaped light beam having a second perimeter that is different than the first perimeter. The controller supplies the lens control signals to the tunable lens, to thereby control the second perimeter of the second geometric-shaped light beam.
