Pixelated Lighting Control via Relative Light Source Location
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pixelated lighting systems struggle to provide a coherent light experience when multiple devices render independent light effects simultaneously, leading to inconsistencies in ambiance due to misalignment and differing light effects from various sources.
Innovation Solution
A system and method for controlling pixelated lighting devices that involve determining the location of nearby light sources, adjusting original light settings based on these locations and the light settings of nearby sources, and controlling individually addressable light segments to emit light according to these adjusted settings, thereby minimizing differences and ensuring a coherent light experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple pixelated lighting devices render independent light effects simultaneously, then each device can operate autonomously with its own light settings, but inconsistencies in ambiance and light coherence occur across the space
Solution Approach 1:
The system implements feedback by having each pixelated lighting device detect nearby light sources and their settings, then adjust its own light output accordingly. This creates a feedback loop where devices respond to their environment and each other, ensuring coherent ambient light while maintaining independent operation capabilities
Solution Approach 2:
The system changes light parameters (color temperature, intensity, hue) based on the detected settings of nearby light sources. By dynamically adjusting these parameters, the system ensures that multiple independently operating devices produce coherent ambient light effects without requiring centralized control
2Reliability
If light settings are adjusted to match nearby light sources, then coherence and harmony in ambient light are improved, but the ability to maintain original independent light effects is reduced
Solution Approach 1:
The system dynamically adjusts light settings based on real-time detection of nearby light sources. Rather than being statically fixed, the light parameters can change adaptively while maintaining coherence, allowing devices to switch between matching ambient light and expressing independent effects based on environmental conditions
3Reliability
If light segments are controlled to compensate for nearby light sources, then inconsistencies in the shared space are reduced, but device complexity and control processing increase
Solution Approach 1:
Each pixelated lighting device autonomously detects nearby light sources and adjusts its own segments without requiring complex centralized control. This self-service approach reduces overall system complexity while maintaining ambient light consistency through distributed intelligence

AI summary
A system for controlling a pixelated lighting device (1) is configured to determine a location of a further light source (29) relative to the pixelated lighting device and obtain original light settings (91-99) for the pixelated lighting device. The pixelated lighting device comprises a plurality of individually addressable light segments (11-19) and the original light settings are associated with respective ones of the individually addressable light segments. The system is further configured to obtain a further original light setting (89) for the further light source, adjust the original light settings based on the further original light setting and the relative location of the further light source, and control the individually addressable light segments to emit light according to the adjusted original light settings.
