AI Technical Summary
Existing technologies for achieving automotive roof lighting functions suffer from several problems, including increased system complexity, uneven light spots, localized glare, loose connections, easy failure of coatings or films, difficulty in adapting to three-dimensional curved surfaces, and insufficient safety. They fail to achieve a balance between uniform light emission, adaptability to curved surface processes, interface bonding strength, and overall lifecycle safety and reliability.
By weaving electroluminescent fibers as functional yarns and structural yarns into an automotive fabric headliner, and combining heat setting and mold hot pressing processes, the light-emitting units are embedded in the three-dimensional structure of the fabric. This ensures that the electroluminescent fibers are evenly distributed, avoids the additional structural redundancy and interface delamination risks of external lamps, meets the atmosphere creation and auxiliary lighting needs of the smart cockpit, and improves structural stability and functional durability through the precise design of conductive, insulating and sealing layers.
It achieves a soft and uniform light effect without light spots or glare, meeting the high-quality requirements of smart cockpits, and improving the structural stability and functional durability of the product under harsh conditions such as vehicle vibration and thermal cycling, thus meeting the safety, environmental protection and mass production feasibility requirements of automotive interiors.
