Vehicle Illumination Lens Routing for Transparent Element Sub-Groups
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle illumination systems require a large number of individually controlled light sources to achieve dynamic illumination effects, leading to complexity and inefficiency.
Innovation Solution
An illumination system with a lens element that redirects light bundles from multiple light sources to different sub-groups of transparent elements, allowing fewer light sources to illuminate a larger number of elements, reducing the overall number of required light sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple light sources are used to illuminate different sections of the vehicle body component, then the illumination coverage and dynamic lighting effects are improved, but the number of light sources increases leading to higher system complexity and cost
Solution Approach 1:
The vehicle body component is segmented into multiple transparent elements (first transparent element, second transparent element, etc.) that can be independently illuminated. Each transparent element or group of elements can display different lighting patterns, enabling dynamic illumination effects while using fewer light sources compared to illuminating each section separately.
Solution Approach 2:
Each light source is designed to illuminate multiple transparent elements simultaneously. For example, the first light source illuminates both the first transparent element and the second transparent element, making the light source multi-functional. This reduces the total number of light sources needed while maintaining comprehensive illumination coverage.
2Ease of operation
If each illuminated section is associated with a specific light source, then precise control of illumination patterns is achieved, but the control system becomes more complicated
Solution Approach 1:
Light sources are designed to control multiple transparent elements. The first light source controls both the first transparent element and the second transparent element, reducing the number of control channels needed while maintaining the ability to create different illumination patterns through coordinated control of the light sources.
Solution Approach 2:
The control functions for multiple transparent elements are merged into fewer light sources. Instead of having separate light sources for each transparent element, the patent combines the illumination function for multiple elements into single light sources, simplifying the control architecture.

Implementation Method 1
the lens element is configured to receive a first light bundle from a first light source and emit said first light bundle, preferably along the main direction of light propagation, and to receive a second light bundle from a second light source and emit said second light bundle
