Patent number: 10004126Abstract: In a lighting system that emits light of a color within a color specification, the color is controlled by adding light from a single color-correcting light emitting device (light-emitting device) to a primary light-emitting device. In an illustrative embodiment, a color-detecting module can sense the color of the combined light emitted from both the primary and the color-correcting light-emitting devices. The color-control system can generate an amplitude control signal based on a signal indicative of the color sensed by the color-detecting module. A color range of the combined light of the primary and the color-correcting light-emitting devices can intersect a domain of the predetermined color specification, as the generated amplitude control signal spans the domain. Using a single color-correcting light-emitting device to maintain a lighting system's emitted color within a predetermined color specification can advantageously reduce system complexity.Type: GrantFiled: June 22, 2015Date of Patent: June 19, 2018Assignee: Goodrich Lighting Systems, Inc.Inventor: Philippe Lapujade

Publication number: 20140160774Abstract: A dual-color aviation Anti Collision Light (ACL) has a first set of LEDs that emit a substantially white beam of light and a second set of LEDs that emit a substantially red beam of light. The ACL can be operated in a first mode in which the red LEDs are excited by themselves so that the ACL produces a red beam of light In a second mode, the white LEDs and the red LEDs are excited simultaneously to produce a white beam of light having a chromaticity within the definition of Aviation White. Operating the red LEDs in the white mode has two synergistic effects. First, the red LEDs augment the luminous output of the white LEDs so that fewer white LEDs are required, thus saving cost and space. Second, the red LEDs shift the chromaticity of total light output toward the red region. This has the effect of compensating for the tendency of the white LEDs to become greener with age.Type: ApplicationFiled: December 6, 2012Publication date: June 12, 2014Applicant: Goodrich Lighting Systems, Inc.Inventor: Philippe LAPUJADE

Patent number: 8750159Abstract: A system for self-organizing and auto-configuring mesh networks is disclosed. Special nodes (deemed special for their topological significance) are used as a starting point for forming clusters of fully connected nodes. Here, all nodes can communicate directly with one another and links are scheduled to meet the traffic requirements as indicated by their individual configuration and topological positions. Links that do not interfere with each other are scheduled to operate concurrently, thereby increasing the bandwidth offered by the whole system. When a node leaves or is introduced to the system, the system will adjust with minimum impact on its operation. Once all of the clusters are formed in a system, the clusters are now capable of inter-cluster communications with an increase in bandwidth for such communications.Type: GrantFiled: October 20, 2008Date of Patent: June 10, 2014Assignee: Natural Lighting Systems, Inc.Inventors: Alexander L.
