Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle headlamp lighting systems with reflective type lighting devices suffer from light loss and complex optical performance due to the use of shutters and separate surface structures on reflectors, which reduce glare avoidance and zone III beam generation efficiency.
Innovation Solution
A lighting module comprising a first light source and two optics, where the second optics redirects light to create a zone III beam without the need for a shutter or separate surface structure on the reflector, enhancing light utilization and simplifying the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a shutter is used to block light and avoid glare, then glare to oncoming drivers is reduced, but light loss increases and utilization efficiency of the light source decreases
Solution Approach 1:
The lighting system is segmented into multiple independent optics (first optics for main beam, second optics for zone III beam). Each optics processes a specific portion of light from the light source, allowing selective redirection of different light paths without blocking any light, thus eliminating glare while maintaining full light utilization.
Solution Approach 2:
The second optics acts as an intermediary element that intercepts light that would otherwise be blocked by a shutter and redirects it to create the zone III beam. This intermediary approach converts what would be wasted light into a useful beam component, eliminating the need for light-blocking shutters.
2Object-affected harmful factors
If a separate surface structure is designed on the reflector to generate zone III beam, then the zone III beam is created, but the reflector complexity increases and optical performance for low beam outside zone III deteriorates
Solution Approach 1:
The lighting system separates the beam generation functions into distinct optics: the first optics handles the main low beam, while the second optics is dedicated to zone III beam generation. This segmentation eliminates the need for complex surface structures on the reflector, keeping each optical component simple and optimized for its specific function.
Solution Approach 2:
The second optics serves as an intermediary component that specifically handles zone III beam generation without requiring modifications to the main reflector structure. This separate intermediary element maintains the simplicity and optical performance of the main reflector while adding the required zone III beam capability.
3Object-affected harmful factors
If a separate surface structure is designed on the reflector to generate zone III beam, then the zone III beam is created, but the physical space of the reflector is occupied and module complexity increases
Solution Approach 1:
The system is divided into separate functional modules: the first optics for main beam and the second optics for zone III beam. This segmentation allows each module to be independently optimized and simplifies the overall structure by eliminating the need for integrated complex surface structures on a single reflector.
Solution Approach 2:
The second optics acts as an intermediary module that adds zone III beam functionality without requiring space modifications to the main reflector. This modular intermediary approach increases adaptability while maintaining structural simplicity and reducing overall module complexity.
