Vehicle Lighting Arrangement with Integrated Projector Beam Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle interiors, particularly aircraft cabins, the integration of projector modules for image projection and lighting systems is challenging due to limited space, leading to disrupted lighting and inefficient use of installation space, where projection modules often interrupt light strips and reduce effective lighting coverage.
Innovation Solution
The integration of projector modules and lighting systems is enhanced by configuring luminaires and projectors to share a seamless beam area, with luminaires designed to accommodate projector light exit openings and projectors featuring additional luminescent areas, allowing for a harmonious and space-efficient combination of lighting and projection technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If projector modules are integrated into the interior of a vehicle, then image projection functionality is added, but the lighting continuity and uniformity are disrupted
Solution Approach 1:
The patent combines the projector module and luminaire into a single integrated unit where the projector housing serves dual purposes: as structural housing for projection components and as part of the lighting system. The luminous area is positioned to overlap with the projection beam opening, allowing both projection and lighting functions to operate simultaneously from the same spatial location without interrupting lighting continuity.
Solution Approach 2:
The patent applies different optical properties to different regions of the integrated module. The luminous area emits diffuse light for general illumination, while the beam opening is optimized for directed projection light. This local differentiation allows each function to operate at optimal performance while maintaining overall system integration.
2Adaptability or versatility
If projector modules are integrated into the interior of a vehicle, then image projection functionality is added, but the installation space efficiency is reduced
Solution Approach 1:
The projector housing and luminaire housing are merged into a single integrated structure, eliminating the need for separate mounting spaces. The overlapping spatial arrangement of the luminous area and beam opening allows both components to share the same installation volume, maximizing space utilization in the vehicle interior.
Solution Approach 2:
The integrated module serves multiple functions simultaneously: the housing provides structural support for both projection and lighting components, the luminous area contributes to ambient lighting, and the beam opening enables image projection. This multi-functionality reduces the overall number of separate components needed in the vehicle interior.
3Adaptability or versatility
If the beam opening is positioned in the luminous area, then seamless integration is achieved, but the structural complexity of the luminaire increases
Solution Approach 1:
The patent merges the projector housing and luminaire housing into a single integrated structure, where the beam opening is positioned within or overlaps with the luminous area. This spatial integration allows projection light to pass through the luminaire housing without requiring separate mounting structures, reducing overall system complexity despite the functional integration.
