Solution Overview
Problem
Conventional LED panel lighting systems rely on flat sheets that require framing to achieve desired shapes, leading to increased costs and complexity in assembly, whereas there is a need for a more efficient and cost-effective solution that provides uniform light distribution and integrates solar energy harvesting.
Innovation Solution
A one-piece, optically-transmissive panel that spans more than 180° about a central axis, featuring an array of LEDs along its edge surfaces, circuitry for power connection, and optional solar energy collection, along with a light modification layer for enhanced light distribution, allowing for a conical or curved design with integrated solar power and reduced voltage requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional LED panel lighting systems use flat sheets with framing to achieve desired shapes, then the structural stability and shape definition are improved, but the assembly complexity and manufacturing costs increase
Solution Approach 1:
The patent merges the panel body and framing structure into a single integrated bent panel component. The optically-transmissive panel is formed with integrated edge surfaces and bending geometry that eliminates the need for separate framing elements, thereby reducing assembly complexity while maintaining structural stability and desired panel shapes
Solution Approach 2:
The patent employs curved and bent panel geometries spanning more than 180° about a central axis, including conical and continuously curved configurations. This curvature principle allows the panel to achieve complex shapes and orientations without traditional framing, simplifying the overall structure while maintaining structural integrity
2Ease of manufacture
If conventional LED panel lighting systems use flat sheets with framing, then the manufacturing process is standardized, but the manufacturing costs and assembly time increase
Solution Approach 1:
By integrating multiple structural functions into a single bent panel component, the patent reduces the number of parts that need to be manufactured and assembled. This consolidation improves manufacturing efficiency by reducing component count and assembly operations, directly addressing both manufacturing efficiency and assembly time concerns
3Illumination intensity
If LED arrays are disposed along edge surfaces of bent panels, then the light distribution uniformity is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The bent panel geometry with integrated edge surfaces provides inherent geometric references and mounting surfaces for LED arrays. The curvature and bending create natural positioning features that guide LED placement, reducing the need for high-precision manufacturing while achieving uniform light distribution along the curved edge surfaces
