    Abstract: A lighting device for a vehicle. The lighting device has a PAR form fit, and includes a housing with a circumferential wall. The circumferential wall has an inner surface, an outer surface and an opening for light emission. The device includes a plurality of light emitting semiconductor devices. The plurality of light emitting semiconductor devices are mounted on a surface of a substrate such that the peak emitted light intensity direction of each one of the plurality of light emitting semiconductor devices is directed toward the central axis. A second surface of the substrate is in thermal contact with the inner surface of the circumferential wall. The device also includes a plurality of curved reflecting surfaces arranged between the plurality of light emitting semiconductor devices and the central axis, arranged to reflect light emitted by the plurality of light emitting semiconductor devices through the opening.

    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: Methods, devices and systems are provided for harmonizing output display characteristics of one component with those of other components onboard a vehicle, such as an aircraft. A line-replaceable unit (LRU) suitable includes a display driver to be coupled to a display command bus, a data storage element to maintain calibration information for the display driver, and a control module coupled to the display driver and the data storage element to identify a current state of an input command signal from the display command bus, identify an adjustment for the display driver based on the calibration information using the current state of the input command signal, and automatically operate the display driver in accordance with the adjustment.

    Abstract: A lighting device including a plurality of light-emitting semiconductor devices. The light-emitting semiconductor devices are separated into at least two subgroups. The lighting device further includes a plurality of optics separated into at least two subgroups, which are arranged relative to the plurality of light-emitting semiconductor devices such that each one of the plurality of light-emitting semiconductor devices of a first subgroup is located at a focal point of a respective optic of a first subgroup of the plurality of optics, and such that each one of the plurality of light-emitting semiconductor devices of a second subgroup is located at a focal point of a respective optic of a second subgroup of the plurality of optics. The optical properties of the first subgroup and second subgroup of the plurality of optics are different. The lighting device further includes a controller module configured to control at least two current signals supplied from a power source to each of the at least two subgroups of light-emitting semiconductor devices, respectively. The controller module is configured to modify the beam width and the peak intensity of the emitted beam of light by varying the magnitude of the respective at least two current signals.
