Stage Lighting Control System for Moving Props
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In stage environments, manually controlling lighting to synchronize with moving props is inefficient and often results in shadowing, as existing systems lack real-time positioning and adaptive illumination capabilities.
Innovation Solution
A system that uses a location detector to wirelessly communicate the prop's position to a controller, which calculates new light positions to minimize shadowing by automatically adjusting the pointing direction of controllable lights in real-time, ensuring precise illumination matching the prop's movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual control is used to adjust lighting to follow moving props, then the lighting can be adjusted without complex automated systems, but the synchronization precision is poor and shadowing occurs
Solution Approach 1:
The system uses location detectors to continuously monitor prop positions and feeds this information back to the lighting control system. The controller automatically adjusts lighting positions based on real-time prop location data, eliminating the need for manual adjustment while achieving precise synchronization without shadowing.
Solution Approach 2:
The patent replaces manual mechanical adjustment of lighting positions with an automated electronic control system. The controller receives digital location data from detectors and automatically calculates and adjusts lighting positions, substituting human operation with an automated feedback-controlled system.
2Productivity
If automated lighting control systems are implemented to track moving props, then lighting synchronization precision improves, but the device complexity increases
Solution Approach 1:
The lighting control system is designed to universally track any moving prop on stage by receiving location data from various types of detectors. The same controller handles both manual and automated modes, and can track multiple props simultaneously, reducing overall system complexity through multi-functionality.
Solution Approach 2:
The system enables lighting to automatically follow prop movement without requiring manual intervention. The controller autonomously calculates optimal lighting positions based on prop location data and executes adjustments independently, making the system self-sufficient and reducing operational complexity.
3Reliability
If real-time location detection is implemented to track prop movement, then lighting synchronization accuracy improves, but the system complexity and cost increase
Solution Approach 1:
The system introduces location detectors as intermediary devices that bridge the gap between prop movement and lighting control. These detectors independently measure prop positions and convert them into usable location data, simplifying the overall system architecture by separating detection from control functions.

AI summary
Movable items on a stage have their position detected in three dimensions, and multiple different lights can be shined at the moving items even after they are moved. Shadowing can be detected and compensated.
