Innovation Solution
A vehicle light optical element assembly is designed with a low-beam primary optical element and a high-beam primary optical element integrated with a lens, featuring condensation parts and light passing parts that form cut-off line structures, allowing for focusing and collimation of light to create distinct low-beam and high-beam lighting shapes without increasing size, and reducing installation errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the reflection element coverage range is increased to ensure system light efficiency, then light efficiency is improved, but the overall system size increases
Solution Approach 1:
The patent merges the reflection element and light shield plate into a single integrated optical element. The light shield plate is designed with a reflective surface that combines the functions of both components, eliminating the need for separate reflection elements and reducing overall system size while maintaining light efficiency
Solution Approach 2:
The light shield plate is designed to perform multiple functions simultaneously: it shields light in certain directions, reflects light to the optical lens, and forms part of the optical path. This multi-functional design reduces the number of components needed while maintaining system performance
