Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gradient mood lights struggle to achieve a gradient lighting effect on high-gloss surfaces due to low reflectivity and visibility issues during daytime outdoor environments, leading to limitations in design and increased costs.
Innovation Solution
A lighting device featuring a light guide plate disposed at a predetermined angle with respect to a garnish body, utilizing a direct lighting method to achieve a gradient lighting effect by varying the intensity of light along the lighting area, with adjustable optical structures and hole sizes to enhance luminance and design freedom.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a gradient mood light uses a reflective surface to radiate light, then the lighting effect can be achieved in dark environments, but the reflectivity is very low on high-gloss surfaces and visibility is poor in daytime outdoor environments
Solution Approach 1:
The patent introduces a light guide plate as an intermediary component between the light source and the garnish body. The light guide plate receives light from the LED and guides it to the lighting area on the garnish body, mediating the light transmission process. This intermediary approach allows the system to achieve reliable lighting effect regardless of the garnish surface's reflectivity properties, solving the problem of inconsistent performance on high-gloss surfaces versus matte surfaces.
Solution Approach 2:
The patent replaces the optical reflection mechanism with a direct light guide mechanism. Instead of relying on the garnish surface to reflect light (optical mechanism dependent on surface properties), the system uses a light guide plate to directly transport light to the lighting area. This substitution eliminates the dependency on surface reflectivity, providing consistent lighting visibility across different surface types and daytime outdoor conditions.
2Illumination intensity
If the light guide plate is disposed parallel to the garnish body, then the structure is simple, but the gradient lighting effect cannot be achieved
Solution Approach 1:
The patent applies asymmetry by disposing the light guide plate at a predetermined angle (non-parallel orientation) relative to the garnish body. This asymmetric configuration allows light to be guided along an inclined path, creating a gradient lighting effect where light intensity varies across the lighting area. The angled arrangement transforms the uniform light output into a spatially varying gradient pattern, achieving the desired aesthetic effect while maintaining relatively simple structural implementation.
3Adaptability or versatility
If the lighting device uses indirect lighting through reflective surfaces, then the design is constrained by surface properties, but material costs and design freedom increase when alternative solutions are sought
Solution Approach 1:
The patent creates a universal lighting solution that works effectively on all garnish body surface types (high-gloss, matte, textured, etc.) regardless of their optical properties. The light guide plate-based direct lighting mechanism is not dependent on surface reflectivity, making the system universally applicable across different materials and finishes. This universality provides design freedom without requiring complex manufacturing adjustments for different surface types, as the same lighting structure achieves consistent results on all surfaces.
