Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current motor vehicle headlight systems face challenges with high electronic complexity and heat generation due to the large number of LEDs required for high-resolution light distributions, which complicates achieving the necessary intensity and field of view while adhering to legal standards.
Innovation Solution
The system employs two light modules with matrix-arranged pixel light segments, where the first and second light distributions are vertically and horizontally offset to overlap, creating a combined light distribution that enhances resolution and homogeneity, using MiniLEDs and a control device to independently manage light pixels for low and high beam distributions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the number of LEDs is increased to achieve higher resolution light distribution, then the resolution is improved, but the electronic complexity increases
Solution Approach 1:
The patent divides the light distribution system into multiple light modules, each containing a subset of LEDs arranged in matrix-like patterns. By segmenting the overall LED array into modular units with shared control structures, the system achieves high resolution through combination while maintaining manageable electronic complexity at each module level.
2Illumination intensity
If the intensity of individual LEDs is increased to achieve legally required intensity, then the illumination intensity is improved, but the temperature increases
Solution Approach 1:
The patent distributes the total light output requirement across multiple light modules rather than relying on a single high-intensity LED array. This segmentation allows each module to operate at moderate intensity levels, reducing heat generation per module while achieving the required overall illumination through the combined output of multiple modules.
Solution Approach 2:
The patent combines the light output from multiple modules to achieve the required overall intensity. By merging several moderate-intensity modules working in parallel, the system reaches legally required illumination levels without the excessive heat generation that would result from using a single high-intensity configuration.
3Device complexity
If a single light module is used to generate light distribution, then the device complexity is reduced, but the field of view is limited
Solution Approach 1:
The patent employs multiple light modules arranged in specific spatial configurations, each module contributing to different portions of the overall light distribution pattern. This segmented approach enables coverage of a broader field of view while keeping each individual module relatively simple in design.
Solution Approach 2:
The patent extends the light distribution system from a single-plane module to a multi-plane or multi-dimensional arrangement of modules. By distributing modules across different spatial positions and orientations, the system achieves an expanded field of view that would be impossible with a single module, while each module itself remains structurally simple.
