Patent number: 9725033Abstract: The present disclosure is generally directed to an interior lighting system for an aircraft, in which individual lighting elements (or groups of lighting elements) can be controlled to emit light of various colors and brightness according to the position of a cart, such as a galley cart. According to an embodiment, a processor that controls the system receives signals from one or more sensors around the aircraft cabin (e.g., radio frequency identification (“RFID”) readers or optical scanners) that indicate the current position of the cart (e.g., by detecting an RFID tag on the cart) and, based on the position of the cart, sends commands to the various lighting elements around the cabin to execute a lighting scene (e.g., gradually raise the lights as the cart comes through).Type: GrantFiled: October 7, 2016Date of Patent: August 8, 2017Assignee: B/E Aerospace, Inc.Inventor: Eric Johannessen

Publication number: 20160053977Abstract: 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.Type: ApplicationFiled: October 7, 2015Publication date: February 25, 2016Inventors: Eric Johannessen, Jonathan Todzia, Donald LaSala, Gannon T. Gambeski, Matthew Dunn, Luis Sam
