Vehicle Badge Illumination via Segmented LED Arrays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle lighting systems lack the ability to create a dynamic and attractive visual experience through sequential illumination of vehicle badges, which limits their aesthetic appeal and functional versatility.
Innovation Solution
The development of an illuminated badge system that incorporates multiple LED light sources and light guides, allowing for sequential and patterned illumination of indicia and background regions, with independent control of each light source to create a distinctive styling element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a single light source is used to illuminate the badge, then the device complexity is reduced, but the visual appeal and dynamic lighting effects are limited
Solution Approach 1:
The badge illumination system is segmented into multiple independent LED light sources, each positioned to illuminate specific regions (indicia, background, peripheral areas). This segmentation enables dynamic lighting patterns and enhanced visual appeal while maintaining manageable system complexity through modular architecture
Solution Approach 2:
The patent transitions from single-point illumination to multi-dimensional lighting by positioning LED sources at different spatial locations and orientations around the badge. Light guides extend in multiple directions to distribute illumination across various badge regions, creating立体 lighting effects that enhance visual appeal
2Productivity
If multiple LED sources are used to illuminate different regions of the badge, then the lighting effectiveness and visual appeal are improved, but the device complexity increases
Solution Approach 1:
Multiple LED light sources are designed with multi-functionality, where each LED can serve different illumination purposes depending on activation patterns. The same LED array can create welcome sequences, farewell animations, or static illumination modes, allowing the system to perform multiple lighting functions without proportionally increasing physical complexity
Solution Approach 2:
Light guides serve as intermediary elements that couple the LED sources to the badge regions. These light guides simplify the optical design by providing structured light transmission paths, reducing the need for complex reflectors or direct LED positioning, and enabling efficient light distribution across multiple badge areas
