Laminated Rear Window Lighting for Flush Brake Lamp Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rear slider window assemblies for vehicles lack integrated lighting solutions that provide both exterior and interior illumination while maintaining a flush glass appearance and reducing complexity in installation and potential leak paths.
Innovation Solution
A rear window assembly with a lighting device comprising LEDs or other light sources laminated between glass panels, providing a flush glass window with lighting functions for exterior and interior illumination, including brake lights, truck bed illumination, and cabin lighting, integrated within the fixed window panel to eliminate separate lighting assemblies and reduce installation complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate lighting assemblies are installed on the window panel, then lighting functions are provided, but the window assembly becomes thicker and more complex with protruding components
Solution Approach 1:
The lighting device is merged with the window panel by laminating the LED light sources directly between the glass layers during the window manufacturing process. This integration eliminates separate lighting assemblies and protruding components, achieving a flush glass appearance while maintaining all lighting functions (brake lights, truck bed illumination, and cabin lighting).
Solution Approach 2:
The lighting device is nested within the window panel structure by placing the LED light sources between the glass layers. The lighting components are contained within the window assembly itself, similar to a nested doll structure, which reduces overall thickness while preserving functionality.
2Adaptability or versatility
If multiple separate assemblies (window panel and lighting assembly) are used, then lighting functions are achieved, but installation labor and complexity increase
Solution Approach 1:
The window panel and lighting device are merged into a single integrated assembly. The LED light sources are laminated between the glass layers during window manufacturing, creating one unified component that eliminates the need for separate lighting assembly installation, thereby reducing installation labor and complexity.
Solution Approach 2:
The integrated window panel serves multiple functions: it provides the window barrier function and simultaneously houses the lighting device that delivers brake lights, truck bed illumination, and cabin lighting. This multi-functionality reduces the number of separate assemblies needed.
3Adaptability or versatility
If lighting devices are mounted on the exterior or interior side of the window panel, then lighting is provided, but additional brackets and housings increase complexity and potential leak paths
Solution Approach 1:
The lighting device is nested within the window panel by laminating the LED light sources between the glass layers. This eliminates the need for external brackets and housings, as the window panel itself serves as the mounting structure, thereby reducing device complexity and potential leak paths.
Solution Approach 2:
The lighting device and window panel are merged into a single integrated structure. The LED light sources are embedded within the glass layers during manufacturing, eliminating separate mounting components such as brackets and housings that would otherwise be required.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution offers a seamless integration of lighting within the window panel, reducing installation labor and complexity, providing a more aesthetically pleasing and functional rear window assembly with reduced thickness and no protruding lighting components, while enhancing safety and convenience with integrated brake and interior illumination.
Implementation Method 1
A rear window assembly includes a lighting device having one or more strips or rows of light sources, such as a plurality of light emitting diodes (LEDs), such as micro-LEDs

AI summary
A vehicular rear window assembly includes a window panel having an inner glass panel and an outer glass panel laminated together. A lighting device includes a plurality of light sources arranged on a circuit element. The vehicular rear window assembly is configured to be disposed at a rear portion of a cabin of a vehicle. The lighting device is disposed between the inner glass panel and the outer glass panel. The light sources, when electrically powered, emit light that is visible through the outer glass panel of the window panel so as to be viewable by a person viewing the vehicular rear window assembly from exterior and rearward of the vehicle. At least some of the light sources of the lighting device are electrically powered responsive to actuation of a brake of the vehicle to provide a center high mounting stop lamp feature that is integrated within the window panel.
