Solution Overview
Problem
Current multiparameter stage lighting systems face challenges in providing creative graphical control over multiple LED light sources, particularly in efficiently managing the intensity and color of numerous LEDs, which can be burdensome for operators due to the need for manual adjustment of thousands of intensity levels and the complexity of creating graphical content programs.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment of each LED's intensity and color is implemented, then precise control over lighting effects is achieved, but operator burden and complexity increase significantly
Solution Approach 1:
The lighting system is segmented into multiple independently controllable LED modules, each with its own circuit board. This segmentation allows the control system to manage thousands of LEDs through modular groups rather than individual units, reducing operator burden while maintaining precise control over each segment's intensity and color
Solution Approach 2:
Graphical content programs are pre-configured and stored in the system memory, containing all the control data needed for complex lighting effects. When executed, these pre-programmed graphics automatically adjust LED intensities and colors according to the stored instructions, eliminating the need for operators to manually adjust thousands of parameters in real-time
2Adaptability or versatility
If thousands of LEDs are individually controlled, then creative graphical control is achieved, but system complexity and data storage requirements increase
Solution Approach 1:
The system uses graphical content programs that store control data as digital representations of desired lighting effects. Instead of complex hardware controls for each LED, the system copies and executes pre-defined graphical patterns, simplifying the control interface while enabling sophisticated graphical lighting displays through software rather than hardware complexity
3Ease of repair
If modular design with separate circuit boards is used, then serviceability and data storage efficiency are improved, but manufacturing and assembly complexity increase
Solution Approach 1:
Each LED module has its own dedicated circuit board, creating self-contained functional units. This segmentation enables easy serviceability as individual modules can be replaced without affecting the entire system, and allows efficient data storage by assigning specific control data to each modular unit, though it does increase manufacturing and assembly complexity
