Flat Ceiling Lighting Panels for Aircraft Cabin Ambiance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircraft cabin lighting arrangements in the central region above the cabin axis face space constraints due to the Passenger Supply Channel, limiting the ability to create complex lighting scenarios without reducing interior dimensions.
Innovation Solution
The implementation of a ceiling trim arrangement with a central ceiling panel element and lateral ceiling panel elements, each equipped with a flat lighting device that spans a surface section, allowing for the distribution of multiple lighting sources over a two-dimensional area, including planar OLEDs, and optionally using passage openings, translucent sections, or projectors to create flexible and attractive lighting scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the paneling arrangement is positioned close to the outer skin to maximize interior dimensions, then the interior volume is improved, but the space for lighting arrangements in the ceiling region is reduced
Solution Approach 1:
The patent transitions from traditional linear lighting arrangements to a two-dimensional surface-mounted lighting device that extends over a surface section of the ceiling panel. This dimensional change allows the lighting system to utilize the ceiling surface area rather than requiring additional vertical space, thereby resolving the contradiction between maximizing interior volume and providing adequate space for lighting arrangements.
Solution Approach 2:
The lighting device is designed with a flat, extended structure that can be mounted on the ceiling surface without requiring significant vertical clearance. This approach allows the lighting system to be integrated into the ceiling panel itself, maintaining interior volume while providing sufficient lighting functionality.
2Length of stationary object
If traditional lighting arrangements are used in the ceiling trim, then the interior dimensions are maintained, but complex lighting scenarios cannot be produced in the central region
Solution Approach 1:
The lighting device is divided into multiple independently controllable lighting sources arranged in a matrix pattern across the ceiling surface. This segmentation allows different regions of the lighting device to be controlled separately, enabling complex lighting scenarios and patterns while maintaining a flat profile that preserves interior height.
Solution Approach 2:
By arranging multiple lighting sources in a two-dimensional surface distribution rather than a linear or point-source configuration, the system achieves enhanced lighting scenario versatility without increasing vertical dimension. The surface-mounted arrangement allows for patterns, gradients, and regional control that would be impossible with traditional linear lighting.
3Adaptability or versatility
If multiple lighting sources are distributed over a surface region, then complex lighting scenarios are enabled, but the device complexity increases
Solution Approach 1:
Multiple lighting sources are integrated into a single flat lighting device structure that is mounted as one unit on the ceiling surface. This merging approach simplifies installation and structural support requirements while maintaining the capability for complex lighting scenarios through electronic control of the individual lighting sources within the unified device.
Solution Approach 2:
The flat lighting device serves multiple functions: it provides general illumination, creates complex lighting scenarios, and can be controlled to produce different lighting patterns and intensities. This multi-functionality is achieved through a unified structure that houses multiple controllable lighting sources, reducing the need for separate lighting systems for different functions.
