Glass Assembly With Non-Reflective Sealing for Halo Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Luminous glass in vehicles experiences a halo effect around light sources due to reflective sealing components, affecting user comfort and illumination performance.
Innovation Solution
A glass assembly with a non-reflective sealing component between the intermediate layer and the opening, having a refractive index lower than the intermediate layer, to reduce or eliminate the halo effect while maintaining sealing performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealing component is used to isolate the intermediate layer from the outside, then sealing performance is improved, but reflective effect is generated causing halo phenomenon
Solution Approach 1:
The sealing component's optical parameters (refractive index) are changed to match or be lower than the intermediate layer, eliminating the reflective effect while maintaining sealing function. This resolves the contradiction by modifying physical parameters rather than removing the sealing component.
Solution Approach 2:
The sealing component acts as an intermediary between the intermediate layer and external environment. By selecting materials with appropriate refractive indices, it mediates between the conflicting requirements of sealing performance and optical performance, preventing halo effect while maintaining isolation function.
2Reliability
If the sealing component has high refractive index, then sealing performance is improved, but light reflection increases causing halo effect
Solution Approach 1:
The refractive index parameter of the sealing component is specifically controlled to be lower than or equal to the intermediate layer. This parameter change eliminates light reflection at the interface while preserving the sealing component's isolation function, resolving the contradiction between sealing performance and illumination quality.

Function Achieved in This Case
The halo effect is alleviated, enhancing user comfort and illumination performance without affecting the glass's aesthetics or functionality.
Implementation Method 1
the refractive index of the sealing component is smaller than that of the intermediate layer

AI summary
A glass assembly includes a first glass body and a second glass body attached to each other through an intermediate layer, the first glass body and/or the second glass body being provided with an opening or openings suitable for accommodating electronic device, and the electronic device at least including a light-emitting component. A sealing component is arranged between the intermediate layer and the opening to isolate the intermediate layer from the outside of the glass assembly, wherein at least a surface of the sealing component facing the opening is non-reflective, and the refractive index of the sealing component is smaller than that of the intermediate layer.
