AI Technical Summary

Technical Problem

Conventional aircraft lighting systems require multiple reading lights per passenger, which are cumbersome to adjust and inefficient in terms of space, weight, and cost, and existing solutions either maintain multiple lights or lack flexibility in illumination patterns.

Method used

A single lighting unit capable of generating multiple light cones with pixel-based image data, controlled by a central system to adapt to different seating configurations and scenarios, using LEDs, OLEDs, fiber optics, or laser beams, allowing centralized control and adjustment of light intensity, angle, and color.

Benefits of technology

Reduces the number of components, saves space and weight, and enables flexible, efficient illumination tailored to passenger needs, reducing assembly time and cost while providing seamless transitions between lighting scenarios.

Abstract

Lighting device (10) for a passenger transport vehicle, wherein the lighting device comprises: a lighting unit (13) designed to illuminate a projection area (31) differently with a light cone (130) based on a plurality of different lighting patterns; where the lighting patterns are pixel-based image data; an interface (12) to an external system for receiving and sending lighting data; and a control unit (11) designed to control the lighting unit with respect to the different lighting patterns based on the received lighting data; characterized by the fact that the lighting unit (13) is designed to generate multiple light cones in a coverage area of ​​the lighting unit depending on the pixel-based image data, so that a light cone results in a delimited lighting area within the coverage area and only the resulting lighting area is illuminated.
