Solution Overview
Problem
Current motor vehicle headlights face challenges in achieving high light output, compact design, robust operation, and cost-effectiveness, as existing light sources often fail to meet these requirements simultaneously.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple light sources and reflectors are used to achieve high light output, then illumination intensity is improved, but device complexity increases
Solution Approach 1:
Multiple individual reflector units are merged into a single integrated mirror device with multiple mirrors arranged in a specific geometric configuration. The mirrors work together as a unified optical system to bundle light from multiple sources into a common main beam, reducing structural complexity while maintaining high illumination output
Solution Approach 2:
The mirror device is segmented into multiple individual mirrors, each assigned to a specific light source and beam path. This segmentation allows each mirror to be optimized for its specific function while collectively achieving the desired light distribution and intensity through their coordinated arrangement
2Illumination intensity
If light sources and optical components are arranged to achieve desired light distribution, then illumination quality is improved, but volume of headlight increases
Solution Approach 1:
The optical system utilizes three-dimensional spatial arrangement of mirrors and light sources, with beam paths extending in multiple dimensions. The mirrors are positioned and oriented in 3D space to achieve precise light distribution control without requiring a larger overall headlight volume, as the light manipulation occurs through spatial configuration rather than increased component size
3Illumination intensity
If multiple mirrors are used to deflect and bundle light rays, then light output is improved, but manufacturing cost increases
Solution Approach 1:
Each mirror in the device serves multiple functions: it reflects light from a specific source, directs it along a defined beam path, contributes to the overall light distribution pattern, and helps bundle the final main beam. This multi-functionality reduces the need for additional specialized components, simplifying manufacturing while achieving high light output

AI summary
A motor vehicle headlight with a mirror device (100) for deflecting and focusing at least two incident, collimated light rays (211-218) into a common main light beam. Each of the incident light rays (211-218) enters the mirror device (100) along an associated direction of incidence perpendicular to a principal plane (101) of the mirror device (100). The main light beam is oriented perpendicular to the principal plane (101) of the mirror device (100). The mirror device (100) has at least two mirrors for each incident light ray (211-218), which are arranged in the beam path of the respective light ray (211-218), namely a deflecting mirror and a central mirror. Each deflecting mirror has an orientation that deflects the associated incident light ray (211-218) from its respective direction of incidence to the associated central mirror.Each central mirror has an orientation that deflects the light beam (211-218) thus redirected onto it in the direction of the main light beam. The central mirrors are positioned relative to each other in an arrangement in which the paths of the light beams (211-218) lie next to each other when viewed in the direction of the main light beam.
