Anamorphic Lens Headlamp for Compact High Beam Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Matrix headlamp technology requires complex and costly primary optics to achieve the desired light distribution for high beam applications, which increases production costs and occupies more vehicle space.
Innovation Solution
The use of an anamorphic lens with distinct upper and lower areas of different curvatures and focus positions, eliminating the need for primary optics and allowing for a more compact design by spacing the light source part closer to the lens incident plane, thereby reducing costs and increasing space efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If primary optics are used to collect light at the focal point of the secondary lens, then light distribution is improved, but device complexity and production cost increase
Solution Approach 1:
The patent removes the primary optics component from the traditional headlamp structure. By using a lens part with a specific anamorphic shape (different curvatures in vertical and horizontal directions), the system directly forms the desired light distribution pattern without requiring separate light-collecting optics, thus simplifying the overall structure while maintaining effective illumination.
Solution Approach 2:
The lens part performs multiple functions simultaneously: it acts as both the light-distributing element and the focusing element. The anamorphic lens design allows it to control light distribution in both vertical and horizontal directions while also focusing light at different focal points, replacing what would traditionally require multiple separate optical components.
2Illumination intensity
If primary optics and brackets are added to achieve proper light focusing, then illumination quality is improved, but manufacturing cost increases
Solution Approach 1:
The patent combines the functions of primary optics and secondary lens into a single integrated lens part. The anamorphic lens design integrates light collection, focusing, and distribution functions into one component, eliminating the need for separate primary optics and reducing assembly requirements, thereby lowering manufacturing complexity and cost.
3Illumination intensity
If the light source is positioned farther from the lens to achieve proper focus, then light distribution is improved, but the occupied space increases
Solution Approach 1:
The patent changes the optical parameters by using an anamorphic lens with different curvatures in vertical and horizontal directions. This allows the system to achieve proper light focusing and distribution with a shorter object distance between the light source and lens, thereby reducing the overall space required for the headlamp assembly.
