Solution Overview
Problem
Conventional connected lighting systems fail to effectively render lighting scenes that account for the relative location and orientation of light sources and users within an environment, limiting the dynamic and spatial aspects of lighting effects.
Innovation Solution
A lighting system comprising sensors in each illumination source to detect location, orientation, luminaire type, and distance, with a controller that adapts control signals to render the lighting scene relative to a user-defined or user-specified point, allowing for dynamic and spatially aware lighting effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional connected lighting systems use fixed light sources with pre-programmed settings, then the control simplicity is maintained, but the adaptability to user location and spatial context is reduced
Solution Approach 1:
Each illumination source is equipped with sensors (location, orientation, distance) that automatically detect its own state and environmental context. The system performs self-configuration and self-adjustment without requiring manual user input for spatial parameters, enabling automatic adaptation to user location and spatial context while maintaining relatively simple control interfaces
Solution Approach 2:
The system continuously monitors spatial parameters through sensors in each illumination source and uses this feedback to dynamically adjust lighting effects. The controller receives real-time data on location, orientation, and distance, then adapts control signals accordingly, creating a closed-loop system that improves adaptability while managing complexity through automated feedback mechanisms
2Manufacturing precision
If lighting effects are rendered without considering illumination source locations, then the rendering simplicity is maintained, but the spatial accuracy and realism are reduced
Solution Approach 1:
The system performs preliminary detection of spatial parameters (location, orientation, distance) before rendering lighting effects. This advance measurement and characterization of the illumination source state allows the controller to pre-calculate appropriate control signals, improving spatial accuracy while managing processing complexity through staged computation
Solution Approach 2:
The controller dynamically adjusts control parameters based on detected spatial characteristics. By changing control signal parameters in response to measured location, orientation, and distance values, the system achieves spatially accurate lighting effects. This parameter adaptation approach improves precision while controlling complexity through systematic parameter transformation
3Ease of operation
If the lighting scene is defined independently of user position, then the scene rendering consistency is maintained, but the user-centric immersion is reduced
Solution Approach 1:
The sensor system serves multiple functions: detecting location for spatial positioning, determining orientation for directional control, and measuring distance for effect scaling. This multi-functional detection approach enhances user-centric immersion across different lighting scenarios while managing overall system complexity through unified sensing mechanisms
Solution Approach 2:
The lighting scene rendering is made dynamic by continuously adjusting it based on real-time user position and environmental context. The system transitions from static, fixed rendering to dynamic, adaptive rendering that responds to user movement and spatial changes, significantly improving immersion and ease of operation through automated dynamic adaptation
