Solution Overview
Problem
Existing motor vehicle lighting devices suffer from light deflection and shadow areas due to the presence of connecting bridges in their optical systems, leading to inhomogeneities and light losses in the light beam.
Innovation Solution
Incorporating an optical structure with a perpendicular input face and prismatic output face in the connecting bridge to minimize refraction and maintain light rays along the optical emission axis, eliminating shadow zones and ensuring even light distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a connecting bridge is used to connect the primary and secondary optical elements, then the structural integrity and alignment of the optical system is improved, but light deflection and shadow areas are created, resulting in light loss and inhomogeneities in the light beam
Solution Approach 1:
An optical structure acts as an intermediary element within the connecting bridge to guide light rays from the primary optical element through the bridge to the secondary optical element. This intermediary structure minimizes refraction and prevents shadow areas, allowing the connecting bridge to maintain structural integrity while preserving light transmission efficiency.
2Stability of the object's composition
If a connecting bridge is used to connect the primary and secondary optical elements, then the structural integrity and alignment of the optical system is improved, but shadow areas and inhomogeneities in the light beam are created
Solution Approach 1:
The optical structure serves as a mediator that maintains the alignment between primary and secondary optical elements while ensuring uniform light distribution. By guiding light rays through the connecting bridge with minimal refraction, it prevents shadow areas and maintains illumination homogeneity across the entire light beam.
3Loss of energy
If the input face of the optical structure is made perpendicular to the light rays, then refraction is minimized and light loss is reduced, but the optical structure requires precise positioning and orientation
Solution Approach 1:
The optical structure is designed to automatically align itself with the light rays from the primary optical element. The perpendicular input face configuration allows the structure to self-position and self-orient based on the light ray direction, minimizing refraction and light loss without requiring complex external positioning mechanisms or high-precision manual alignment.
