This Dual-mode Search and Landing Light provides two beams: a
white beam and an infrared beam (dimmable for use with night vision
goggles). This dual white/IR light consists of halogen lamps with
their reflectors, Infra-Red lights and their filters and
reflectors, beam spread orientation means (motor, gear, position
devices), a mechanical structure, an electrical interface and an
electrical circuit to control light sources and adjust Infra-Red
radiant intensity.
Halogen technology provides higher luminous efficiency, a better
color temperature, and a faster start than classical incandescent
lamps.
