Solution Overview
Problem
There is a need for an illuminated component that can provide multiple colors with a single light source, while appearing as a single color when unlit, and capable of illuminating internal graphics and textured regions to display predetermined patterns.
Innovation Solution
A light system comprising a plurality of light sources and a lens with primary and secondary faces, where the secondary faces include pattern regions that are illuminated to provide multiple colors, and the system is configured to illuminate a region around a vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-color light source is used, then the device complexity is reduced, but the color variety provided is limited
Solution Approach 1:
The lens is divided into multiple regions with different optical properties - some regions contain colorants that filter light to produce different colors, while other regions remain clear. This allows a single light source to generate multiple colors through spatially differentiated local properties of the lens material.
Solution Approach 2:
The lens is constructed as a composite material system combining clear transparent material with regions containing colorants. This composite structure enables the lens to simultaneously transmit unfiltered light and filtered colored light, allowing one light source to produce multiple colors without increasing the number of light sources.
2Device complexity
If multiple colors are provided with one light source, then the device complexity is reduced, but the manufacturing precision requirements increase
Solution Approach 1:
The invention changes the optical parameters of the lens material by incorporating colorants in specific concentrations and distributions. By controlling the concentration and spatial distribution of colorants during manufacturing, the lens can be designed to produce specific color patterns when illuminated, transforming a manufacturing precision challenge into a material composition design solution.
3Shape
If the component appears as a single color when unlit, then the visual appeal is enhanced, but the color information is lost
Solution Approach 1:
The lens is designed to exhibit color changes based on illumination conditions. When unlit, the lens maintains a uniform appearance or shows the color of the housing material. When illuminated, the colorant regions become active and display different colors corresponding to the filtered light, allowing the component to convey color information only when needed for visibility or signaling.
