Transition Light Color Cancellation for Multi-Color LED Fade Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern vehicle lighting systems with multi-color LED strips often produce unintentional mixed colors at transition zones, which can be aesthetically displeasing and distracting.
Innovation Solution
A method and system that adjusts the colors of lights in transition zones by determining and emitting adjustment colors to create a smoother transition between base colors, using a chromaticity color space chart to calculate the adjustment colors, ensuring they are closer to a target color like white, thereby reducing the visibility of unwanted mixed colors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If base lights emit two different base colors simultaneously, then the light array provides color variety and visual interest, but unwanted mixed colors appear at transition zones between the base colors
Solution Approach 1:
The patent introduces transition lights as intermediary elements between base lights emitting different colors. These transition lights emit adjustment colors that mediate the transition between base colors, preventing the direct mixing that creates unwanted colors. The adjustment colors act as a buffer zone, allowing smooth color transitions without generating harmful mixed colors at the boundary.
Solution Approach 2:
The patent applies different color characteristics to different spatial zones: base lights emit saturated base colors in their respective zones, while transition lights emit adjustment colors with reduced saturation specifically at the transition zones. This local differentiation allows the system to maintain color variety in base zones while eliminating unwanted mixed colors in transition zones by adjusting the local color properties.
2Object-generated harmful factors
If transition lights emit adjustment colors to cancel unwanted mixed colors, then the aesthetic quality improves, but the system complexity increases due to additional control calculations
Solution Approach 1:
The patent changes color parameters (hue, saturation, brightness) of transition lights based on the relationship between adjacent base colors. By systematically adjusting these parameters according to chromaticity coordinates and color distance calculations, the system determines adjustment colors that cancel unwanted mixed colors. This parameter-based approach provides a structured method to improve aesthetics without requiring overly complex control logic.
3Measurement precision
If the system uses chromaticity color space calculations to determine adjustment colors, then color accuracy improves, but the computational requirements increase
Solution Approach 1:
The system uses the chromaticity color space framework to enable transition lights to self-determine their optimal adjustment colors based on the colors emitted by adjacent base lights. Each transition light independently calculates its adjustment color by considering the chromaticity coordinates of neighboring base colors, reducing the need for centralized complex computation and allowing the system to serve itself through localized color matching.

AI summary
A method includes receiving data indicating at least two different base colors to be respectively emitted from base lights on opposite sides of at least one transition light of a light array. Each light of the light array has adjustable colors and is covered by one or more light guides, and receiving data of a target color between the two base colors in at least one coordinate dimension on a chromaticity color space chart. The method also includes determining at least one adjustment color on an opposite side of the target color from a mixed color on the color space chart, and providing the at least one adjustment color to be emitted from the at least one transition light when the base colors are being respectively and simultaneously emitted from the base lights on opposite sides of the at least one transition light.
