Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light panels used in interior spaces lack the aesthetic appeal of natural sunlight, failing to convincingly mimic the appearance of a window, which is essential for both biological and psychological well-being.
Innovation Solution
The introduction of a light panel with a gradient color scheme, utilizing a planar waveguide optically coupled with multiple light sources emitting different colors, creates a color gradient that emulates natural sunlight, providing a more convincing 'artificial window' experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a uniform luminous panel is used, then the manufacturing is simple and cost-effective, but the aesthetic appeal and realism of mimicking natural sunlight is poor
Solution Approach 1:
The patent applies local quality by varying the color temperature of different regions of the light panel. The controller adjusts LED groups to create different color temperatures across the panel surface, mimicking the natural gradient of sunlight. This resolves the contradiction by maintaining simple manufacturing processes while achieving aesthetically pleasing gradient effects that resemble natural windows.
2Illumination intensity
If multiple light sources with different colors are used to create gradient, then the aesthetic appeal and realism improve, but the device complexity increases
Solution Approach 1:
The patent segments the light panel into multiple controllable LED groups that can be independently adjusted to create color gradients. This segmentation allows the system to achieve complex aesthetic effects while maintaining manageable device complexity through modular design and centralized control.
Solution Approach 2:
The controller serves multiple functions by managing both the intensity and color temperature of multiple LED groups simultaneously. This multi-functionality reduces overall device complexity by consolidating control logic into a single unit that can create various gradient patterns and lighting scenarios.
3Illumination intensity
If gradient color is introduced to mimic natural sunlight, then the psychological and aesthetic benefits improve, but the manufacturing precision requirements increase
Solution Approach 1:
The patent employs dynamic control of LED intensity and color temperature through a controller that adjusts each LED group independently. This dynamic approach allows the system to create smooth color gradients without requiring extreme manufacturing precision, as the gradients are achieved through electronic control rather than physical material variations.
