Emblem Light Assembly Using Optical Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light assemblies for illuminating emblems require numerous light sources to outline the emblem, leading to issues with physical spacing, heat generation, power consumption, and cost, as well as reduced lifespan due to high temperatures.
Innovation Solution
A light assembly comprising a housing, an emblem, and an optical light guide that receives light from one or a few sources and emits it along the emblem's edges through light scattering elements, eliminating the need for multiple light sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If many light sources are used to illuminate the emblem edges, then the illumination effect is improved, but heat generation increases and light source lifespan decreases
Solution Approach 1:
Multiple light sources are merged into a single light source that illuminates the entire emblem perimeter. The optical light guide distributes the light from this single source along the entire emblem edge, achieving the illumination effect of multiple sources while using only one physical light source, thereby reducing heat generation and extending lifespan.
Solution Approach 2:
An optical light guide is introduced as an intermediary between the single light source and the emblem edges. The light guide receives light from the single source and distributes it along the emblem perimeter, enabling one light source to effectively illuminate multiple locations without requiring multiple light sources to be physically present and generating heat simultaneously.
2Illumination intensity
If many light sources are positioned next to each other, then the illumination coverage is improved, but physical spacing becomes problematic
Solution Approach 1:
Multiple light sources are merged into a single light source combined with an optical light guide. This eliminates the need to physically arrange multiple light sources along the emblem perimeter, simplifying the spatial arrangement while maintaining comprehensive illumination coverage through the light guide's light distribution capability.
Solution Approach 2:
The solution transitions from a one-dimensional arrangement of multiple light sources along the emblem edge to a different approach where a single light source illuminates the optical light guide, which then distributes light along the emblem perimeter. This dimensional shift in the light transmission path resolves the physical spacing problem.
3Illumination intensity
If many light sources are used, then the illumination effect is improved, but power consumption increases
Solution Approach 1:
Multiple light sources are merged into a single light source with an optical light guide system. This consolidation reduces power consumption by eliminating the need to power multiple separate light sources while maintaining the desired illumination effect through efficient light distribution along the emblem edges.
4Illumination intensity
If many light sources are used, then the illumination coverage is improved, but the number of components and assembly complexity increases
Solution Approach 1:
Multiple light sources and their associated mounting structures are merged into a single light source and one optical light guide component. This significantly reduces the total number of components and simplifies assembly procedures while achieving comprehensive emblem illumination coverage.
