Abstract: A laser light assembly includes a substrate, a reflective phosphor plate, a plurality of laser diodes, a light shield, at least one mirror, a plurality of beam-shaping lenses, and a first lens. The reflective phosphor plate is coupled to the substrate and converts incident blue laser light into white light. The laser diodes emit the blue laser light. The light shield prevents the blue laser light emitted by the laser diodes from escaping the assembly. The mirror reflects the blue laser light emitted from each laser diode toward a predetermined position on the reflective phosphor plate, whereby the reflective phosphor plate emits white light. The beam-shaping lenses are disposed between a different one of the laser diodes and the mirror. The first lens receives the white emitted from the reflective phosphor plate.

Abstract: A single motor, two axis searchlight system includes a shaft, a motor, at least a first plurality of light sources, and a controller. The shaft is mounted for rotation about a rotational axis. The motor is coupled to the shaft and is operable to rotate the shaft about the rotational axis. The first plurality of light sources are coupled to the shaft and are rotatable therewith about the rotational axis. The first plurality of light sources are disposed along a first plane that is disposed at a first angle relative to the rotational axis. The controller is in operable communication with the motor and the first plurality of light sources. The controller configured to: selectively energize the motor to thereby cause the first plurality of light sources to rotate about the rotational axis, and selectively energize one or more of the first plurality of light sources.

Abstract: Systems and methods for an aircraft lighting system (ALS) are provided. The method includes co-locating a central light source subsystem including a blue light generator, red light generator, and green light generator, and a light generating control unit (LGCU) comprising a processor, and distributing a plurality of passive light-heads around an external surface of the aircraft. Each passive light-head of the plurality of passive light-heads is operationally coupled to a first side of a respective light switch of a respective plurality of light switches, the light switch being coupled on a second side to a light emitting output of the central light source subsystem. Controlling and actuating the light generators and the light switches in accordance with a load profile is performed by a light generating control unit (LGCU).

Abstract: Provided systems and methods for an aircraft lighting system (ALS) include a centralized blue generator that supplies blue light to a plurality (N) of passive light-heads distributed at various locations on the aircraft. A load profile for use of the N passive light-heads during all flight phases and operational phases is developed and uploaded into the system. Each of the passive light-heads is operationally coupled to the blue light generator via a respective light transmission element that is gated with a respective one of N light switches. A light generating control unit (LGCU) is coupled to the blue light generator, and controls the generation and actuation of blue light, in addition to controlling light switch positions, as a function of navigation data and the load profile. Each of the N passive light-heads comprises a respective light conversion element to convert the blue light into red, green, or white light.
