Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional AC light emitting diodes connected directly to an AC power source experience issues with continuous lighting and are prone to damage from reverse current, and they suffer from flickering when used in matrix form due to the limitations of unified wire connections, which restrict design enhancements for light intensity and flicker reduction.
Innovation Solution
The AC light emitting diode design employs multiple metal wires to connect electrodes of adjacent light emitting cells in a matrix configuration, allowing for enhanced light intensity and reduced flickering by using two or more metal wires per connection, and incorporates light guide portions to focus and radiate light efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a unified wire connection method is used to connect electrodes of adjacent light emitting cells, then the device complexity is reduced, but the light intensity enhancement and flicker reduction capabilities are limited
Solution Approach 1:
The patent divides the connection structure into multiple independent metal wires instead of using a unified wire. Each metal wire connects specific electrodes of adjacent light emitting cells, allowing independent control and optimization of connection paths. This segmentation enables multiple parallel current paths, enhancing light intensity while maintaining manageable device complexity through modular connection design.
2Illumination intensity
If multiple metal wires are used to connect electrodes of adjacent light emitting cells, then the light intensity is enhanced and flickering is reduced, but the device complexity increases
Solution Approach 1:
The patent combines multiple metal wires into a integrated connection structure where wires are systematically arranged and connected to specific electrodes. The multiple wires work together in a coordinated manner to provide redundant current paths and enhance light output. By merging the functions of multiple wires into a unified connection architecture, the patent achieves improved light intensity and flicker reduction while controlling the increase in device complexity through systematic integration.
3Illumination intensity
If light guide portions are added to enhance light intensity, then the illumination is improved, but the manufacturing difficulty increases due to wire connection constraints
Solution Approach 1:
The patent performs preliminary planning of metal wire connection paths before adding light guide portions to the structure. The connection architecture is designed in advance to accommodate the integration of light guide elements, ensuring that wires can be routed and connected without excessive complexity. This preliminary action allows light guide portions to be added systematically, enhancing illumination while maintaining ease of manufacture through pre-planned integration points and pathways.
