Variable-Color LED Structure for Mixed-Brand Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multiple-color lighting devices face challenges in individually controlling LEDs of different colors and sizes, particularly when mixed brands are used, as conventional systems require individual control of each pixel, which is not feasible with varying LED sizes and thicknesses.
Innovation Solution
A variable-color light-emitting structure is developed, comprising a ground path, current paths, light-emitting elements, and conductive substrate portions that allow for individual control of LEDs, enabling separate control of LEDs emitting different colors by using a system of current paths, connection elements, and conductive substrates to manage control currents effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If individual control of all LEDs is implemented to handle different sizes and thicknesses, then control precision is improved, but device complexity increases
Solution Approach 1:
The patent divides the lighting device into multiple independently controllable units, each containing one or more LEDs of the same color. Each unit has its own control circuit that can independently regulate the current to LEDs within that unit, allowing precise control without needing to control every single LED individually across the entire device.
Solution Approach 2:
Multiple LEDs of the same color are grouped together into a single controllable unit. By merging these similar-colored LEDs into one control domain, the system reduces the number of independent control circuits needed while maintaining the ability to precisely control the overall output of each color group.
2Adaptability or versatility
If mixed brands of LEDs are used to increase color variety, then adaptability is improved, but control difficulty increases
Solution Approach 1:
The patent applies different control strategies to different color groups. Each unit is designed with characteristics optimized for its specific LED color and brand, allowing mixed-brand LEDs to be used while maintaining uniform control through localized circuit design that accounts for specific LED properties.
