Vehicle Lamp Optical Modules for Continuous Line Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lamp technologies face challenges in achieving uniform light distribution patterns and design differentiation, particularly in implementing continuous line-shaped lighting images without disconnection.
Innovation Solution
The vehicle lamp design incorporates multiple optical modules with light sources, sub-light sources, and reflectors, each with a curved reflective surface, to form distinct light distribution patterns that overlap to create uniform low beam and high beam patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If separated optical modules are used according to related art, then device complexity is reduced and ease of manufacture is improved, but light uniformity deteriorates and continuous line-shaped lighting image cannot be achieved
Solution Approach 1:
The patent merges multiple optical modules (first, second, and third optical modules) into a single integrated housing, combining their light distribution patterns to form a continuous line-shaped lighting image. This integration allows the light beams from separate modules to overlap and create uniform illumination, resolving the contradiction between ease of manufacture and light uniformity.
Solution Approach 2:
The patent arranges optical modules in a vertical direction and uses curved reflective surfaces to redirect light beams in multiple dimensions. The reflectors bend light paths to ensure overlapping distribution patterns create a continuous horizontal line-shaped image, utilizing dimensional transformation to achieve uniformity while maintaining modular construction benefits.
2Adaptability or versatility
If multiple separated optical modules are used, then design differentiation is improved, but device complexity increases
Solution Approach 1:
The patent creates a universal housing structure that can accommodate multiple different optical modules with varying light distribution patterns. This multi-functional design allows the same housing to support various module configurations for different lighting modes (low beam, high beam, daytime running lamps), achieving design differentiation without proportionally increasing overall device complexity.
Solution Approach 2:
The patent segments the lighting system into multiple independent optical modules that can be individually designed and manufactured, then integrated into a unified housing. Each module can have different characteristics for design differentiation, while the modular segmentation keeps individual component complexity manageable.
3Device complexity
If conventional optical systems are used, then device complexity is reduced, but continuous line-shaped lighting image without disconnection cannot be achieved
Solution Approach 1:
The patent employs curved reflective surfaces in the optical modules to redirect light beams and create overlapping distribution patterns. The curvature of these reflectors is specifically designed to bend light paths so that adjacent modules' light beams connect seamlessly, forming a continuous line-shaped lighting image without disconnection while maintaining manageable device complexity.
