Concave Light Guide for Uniform Vehicle Interior Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current interior lighting systems in vehicles often result in uneven illumination, with some areas being overly lit while others are underlit, necessitating a solution for a homogeneous light distribution to ensure consistent illumination of vehicle components.
Innovation Solution
A light system comprising a light source and a light guide with a concave region that directs light uniformly across a surface or component, using a guiding device to align the light source with the light guide, ensuring even illumination by projecting light at a predetermined angle and distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional lighting systems are used to illuminate vehicle interior components, then the components become visible, but the light distribution is uneven with some areas overly lit and others underlit
Solution Approach 1:
The light guide employs a concave region with a curved surface geometry that redirects light rays to achieve uniform illumination. The curvature of the concave region causes light to spread evenly across the target surface, transforming the directional light from the LED into a homogeneous distribution pattern that eliminates hot spots and dark areas.
Solution Approach 2:
The light guide structure incorporates different surface geometries in different regions - a concave region for light redistribution and specific exit locations for targeted illumination. This local variation in surface quality allows the system to achieve uniform overall illumination while maintaining consistent visibility across different areas of the vehicle interior component.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a uniform and homogeneous light distribution across vehicle components, eliminating hot spots and ensuring consistent illumination, enhancing visibility and aesthetic appeal within the vehicle interior.
Implementation Method 1
a guiding device; and a light guide in communication with the guiding device, the light guiding device is aligned with the light source so that light from the light source extends into the light guide through the guiding device and extends along a length of the light guide
Implementation Method 2
the light guide has a concave region that light extends through to provide a uniform distribution of light to an article of manufacture within an interior of a vehicle
