Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional lighting systems use monochrome color schemes without zonal control, then the system structure remains simple and cost-effective, but the capability to achieve complex color and intensity effects is limited
Solution Approach 1:
The lighting system is divided into multiple independently controllable zones, where each zone can be individually addressed and controlled for color and intensity. This segmentation enables complex color effects and motion simulations across different regions of the lighting fixture while maintaining a modular structure that manages system complexity.
Solution Approach 2:
Different zones within the lighting system can have different color temperatures, hues, and intensities simultaneously. This local quality variation allows each zone to be optimized for specific effects, enabling cascading colors, motion effects, and other complex visual patterns that require spatial variation in lighting properties.
2Measurement precision
If individual LED arrays are controlled independently with zonal control, then precise color and intensity control is achieved, but the control system complexity increases
Solution Approach 1:
A central controller serves as an intermediary between the user interface and the individual LED arrays. The controller receives control signals and distributes appropriate control parameters to each zone's LED arrays, enabling precise control of color and intensity while abstracting the complexity of individual LED control from the user interface.
Solution Approach 2:
The control system dynamically adjusts the operating parameters of each LED array based on control signals received from the user interface. This dynamic control enables real-time changes in color temperature, hue, and intensity across different zones, achieving precise control adaptability for various lighting scenarios and special effects.

AI summary
A lighting system and method features full gamut color and white color correlated temperature (CCT) control of independently controlled zones. Each zone may be tuned to any color and/or white CCT. The result is a lighting system and method with a light-emitting face having zones of different colors and intensities that may be independently controlled in real time. The lighting system and method enables improved lighting effects for film, television, and still photography as compared to traditional panel lights that are uniform in color over the entire emission surface.
