Vertical Automotive Lighting Module for Uniform Multi-Function Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automotive lighting modules can only ensure one regulatory lighting function at a time, requiring multiple modules for different functions, which results in a non-uniform appearance depending on the activated function.
Innovation Solution
A modular lighting system comprising multiple sub-modules, each with a flat optical guide and a light source, configured to produce either a lighting function with a horizontal cut-off or without, and arranged in an alternating pattern to maintain a consistent appearance across different lighting functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate lighting modules are used to provide different regulatory lighting functions, then the lighting functions can be performed, but the illuminated face will have distinct appearances depending on the activated function
Solution Approach 1:
The patent combines multiple lighting sub-modules (first sub-modules for low-beam with cut-off and second sub-modules for high-beam without cut-off) into a single integrated lighting module. These sub-modules are juxtaposed to form a unified illuminated face that maintains consistent appearance across different lighting functions, eliminating the need for separate modules with different appearances.
Solution Approach 2:
The lighting module is divided into multiple independent lighting sub-modules, each capable of producing specific lighting functions. The first lighting sub-modules produce sub-beams with upper horizontal cut-off, while the second lighting sub-modules produce sub-beams without cut-off. This segmentation allows functional versatility while maintaining appearance consistency through their unified arrangement.
2Shape
If a single lighting module is used, then the illuminated face has a uniform appearance, but it can only provide a single lighting function
Solution Approach 1:
The lighting module is designed to perform multiple regulatory lighting functions simultaneously. By incorporating both first lighting sub-modules (for low-beam with cut-off) and second lighting sub-modules (for high-beam without cut-off) within a single module, it achieves multi-functionality while maintaining a uniform illuminated face appearance.
3Adaptability or versatility
If multiple lighting modules are arranged side by side, then different lighting functions are provided, but the combined output face has distinct illuminated aspects
Solution Approach 1:
Instead of arranging multiple separate modules side by side, the patent merges multiple lighting sub-modules into a single integrated module. The sub-modules are juxtaposed within the same housing to form one unified illuminated face, reducing the overall system complexity while maintaining the capability to provide multiple lighting functions.
