Solution Overview
Problem
Existing edge-lit LED panels face challenges with inferior illumination properties and complex, time- and cost-inefficient assembly due to component arrangement and the need for multiple components.
Innovation Solution
A panel module design featuring a hollow frame with a driver unit positioned behind the optical element, reducing light obstruction and allowing for improved light emission, combined with a method of assembling the module using a few components and 3D-printed segments for easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the driver unit is arranged beside the optical element in prior art panels, then the assembly structure is simple, but the effective light-emitting area is reduced and illumination properties deteriorate
Solution Approach 1:
The driver unit is relocated from a lateral arrangement (beside the optical element in the plane) to a depth-based arrangement (behind the optical element along the light propagation direction). This dimensional shift allows the driver unit to occupy space that does not interfere with the light-emitting area, thereby improving illumination properties without significantly increasing assembly complexity.
2Productivity
If multiple components are used in prior art panels, then the panel structure is robust, but the assembly process becomes time-consuming and cost-inefficient
Solution Approach 1:
The driver unit and power supply components are integrated into a single compact assembly that fits within the hollow portion of the frame. This merging of components reduces the total number of separate parts, simplifies the assembly process, and improves productivity while maintaining structural robustness through the unified design.
3Adaptability or versatility
If the frame is solid in prior art designs, then the structural strength is high, but the RF transparency and component arrangement flexibility are reduced
Solution Approach 1:
The frame is segmented into solid and hollow portions, with the hollow section strategically positioned to accommodate the driver unit. This segmentation provides RF transparency and flexibility for component arrangement while the remaining solid portions of the frame maintain sufficient structural strength for panel support.
