An improved multi-die LED lighting apparatus for use with a lens that facilitates light dispersion while minimizing color banding and maintaining the light distribution intent of the design of the lens. The individual LED die are dithered, both rotationally and spatially relative to neighboring LED dies to minimize color banding of the LED lighting apparatus. The result is an reduction in color banding while seeking to retain the original light dispersion intent of the lens.

Aircraft light unit

An aircraft light device has a base, a printed circuit board, a reflector and a cover-lens. The reflector is comprised of a number of reflective surfaces connected together to form a spline. Light transducers on the printed circuit board are of two main types, light emitters and light receivers. Light emitters provide light for illumination, while light receivers enable detection of received light. The two transducer types can be used alone or in combination.

A configurable lamp assembly has a set of lamp-lens modules and a set of power modules. Each of the various lamp-lens modules can connect to one of the various power modules to provide a variety of lamp assemblies providing various illumination patterns operable from a number of supply voltages.

A lighting fixture employs one or more reverse parabolic reflectors and molded lenses in a faceplate to provide a variety of light output intensities and emission patterns. Some embodiments clip the reverse parabolic reflectors to fit within the outline of the faceplate without sacrificing significant light output.

An aircraft external lighting system and method is applicable to aircraft position, navigation and strobe lights. The lighting system includes a light source, a cylindrical lens adjacent the light source, and a lenticular lens between the light source and the cylindrical lens.

Aircraft external lighting system and method

Light sources in a luminaire attach to the luminaire by one or more tabs. Up to three axis of rotation are possible. Bendable tabs enable a first axis of rotation of the light source. Light sources are rotatable about a mounting point to the tab providing a second axis of rotation. Some tabs are twistable about a third axis of rotation. Some tabs also conduct heat away from the light source. Tabs can also be formed in a baffle plate for new luminaires or for the retrofit of existing luminaires. Multiple types of light sources can be combined to provide luminaires with custom light patterns and intensities.

Luminaire with adjustable light source

An aircraft navigation light comprises a base and circuit board in thermal contact with the base. White and colored LEDs mount on the circuit board. A reflector-shade placed adjacent the LEDs reflects light from the LEDs in desired directions and shades other directions from view of selected LEDs. A light transmissive cover sealed to the base, encloses the circuit board, LEDs and reflector-shade. Temperature responsive circuitry on the circuit board regulates the current through the LEDs and reduces the LED current under high temperature conditions.
