Abstract: A variable geometry light source and related method for illumination comprises a dense array of micro light emitting diodes (LED) incorporated within a printed circuit board and controlled by an incorporated microcontroller. The microcontroller receives user input and causes the dense array to illuminate according to the input. A tunable lens operates to focus the LED illumination toward one or more specific target subjects creating a variable geometry light projection. The microcontroller is configured with instructions which cause the dense array to produce a variety of shapes, intensities, and color temperatures tailored to the individual installation. The microcontroller causes the dense array to create a light projection suitable for illumination of a subject as well as a dynamic projection animated for a communication to the viewer.

Abstract: An integrated aircraft lighting and display panel includes high-density arrays of micro-scale light-emitting diodes (LED) set into a flexible printed circuit board (PCB). The PCB and LED arrays may be set into structural layers corresponding to overhead panels, side panels, bin panels, divider panels, doorway panels, or other interior structural panels of the aircraft. The LED arrays may be activated by a controller to provide cabin lighting, indicate aircraft signage, display high-resolution image or video graphics, or any simultaneous combination of all three. The panel may have a translucent or transparent decorative outer skin which may mimic the outward appearance of wood, stone, bamboo, or other decorative materials while the integrated lighting and display panels are inactive. Highly reflective core materials, such as an aluminum core in a honeycomb pattern, may guide the luminous output of the LED arrays through the outer skin.

Abstract: An integrated aircraft lighting and display panel includes high-density arrays of micro-scale light-emitting diodes (LED) set into arrays (e.g., linear, two-dimensional, freeform) to form tiles, the LED tiles combined and interconnected to form LED panels conformable to any interior surface within an aircraft cabin.

Abstract: A flexible LED lighting module includes a flexible housing and flexible PCB to which LED units are mounted. An encapsulant fills a channel of the flexible housing and has a same or similar optical refractive index value as is used in the LED unit to hold phosphorous particles used for coloring of the LED. Use of the encapsulant changes the color of the light ultimately emitted from the flexible LED lighting module, and this factor is corrected for in calibration processes associated with the flexible LED lighting module.

Abstract: A clamp for holding a twisted lighting unit includes a body member having a slot extending from its top wall to its base. The slot extends from an end wall to a side wall to create a passage for receiving a twisted portion of a lighting unit. Parallel surfaces are provided over a portion of the width of the passage to hold the lighting unit in its intended position. Various curves in the slot receive the twist itself and facilitate insertion of the clamp on the lighting unit and reduce the strain experienced along the edge of the lighting unit.
