A recently granted patent (Publication Number: US11866174B2) discloses a novel lighting system designed to enhance safety and efficiency in various environments, particularly in aircraft aisleways. The system comprises multiple lights strategically placed along a pathway, a sensor to detect the location and velocity of a moving occupant, a processor to generate control signals based on occupant movement, and a controller to illuminate the lights accordingly. The system's unique feature includes adjusting the luminance of the lights based on the magnitude of the occupant's velocity, with specific configurations for different scenarios.

Furthermore, the patent also outlines a method associated with the lighting system, detailing the steps involved in detecting occupant movement, generating control signals, and illuminating the lights based on proximity and velocity criteria. The method emphasizes the proportional adjustment of light luminance to the occupant's velocity, enhancing visibility and guidance in dynamic environments. The system's adaptability to different threshold velocities and distances ensures a responsive and efficient lighting solution for various applications, including aircraft aisleways. Overall, the patented technology offers a sophisticated yet practical approach to lighting control, catering to the evolving needs of modern environments where safety and efficiency are paramount.
