Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting control systems fail to effectively compensate for interference caused by unexpected events such as malfunctioning light sources, alien light sources, or dynamic sunlight, leading to distortions in rendered lighting scenes, especially when color light is used.
Innovation Solution
A closed-loop control system that monitors the lighting scene for deviations, characterizes interference, and reconfigures the lighting system to counteract detected disturbances, enabling autonomous reconfiguration and implicit daylight harvesting for increased energy efficiency.

1Extent of automation
If a lighting control system automatically renders a lighting scene using multiple light sources, then the lighting atmosphere or scene can be efficiently controlled with numerous control parameters, but the system becomes vulnerable to interference from unexpected events such as malfunctioning light sources, alien light sources, or dynamic sunlight
Solution Approach 1:
The system continuously monitors the rendered lighting scene by scanning and comparing actual light intensities against reference values. When deviations are detected (indicating interference from malfunctioning sources, alien sources, or sunlight), the system triggers a reconfiguration process that adjusts control parameters to counteract the interference and restore the intended lighting atmosphere.
Solution Approach 2:
The lighting control system performs self-diagnosis and self-correction by automatically detecting interference conditions and reconfiguring itself without external intervention. The system characterizes the type of interference detected and autonomously computes new configuration settings to compensate for the disturbance.
2Reliability
If the system monitors and detects interference in the rendered lighting scene, then the reliability of the lighting scene can be improved, but the device complexity increases due to additional monitoring and characterization components
Solution Approach 1:
The control device integrates multiple functions into a single system: it serves as both the renderer of the lighting scene and the monitor for detecting interference. The same control infrastructure that manages light source parameters is also used to scan and analyze the rendered scene, eliminating the need for completely separate monitoring hardware.
Solution Approach 2:
The system uses feedback from the rendered lighting scene to trigger reconfiguration only when necessary. By continuously scanning and comparing actual performance against reference values, the system activates complex characterization and reconfiguration processes only when deviations indicate interference, rather than operating continuously at full complexity.
3Stability of the object's composition
If the system reconfigures the lighting scene to counteract detected interference, then the consistency of the lighting atmosphere can be maintained, but the loss of time increases due to the characterization and reconfiguration process
Solution Approach 1:
The system pre-characterizes different types of interference (malfunctioning light sources, alien light sources, sunlight) and has pre-computed reconfiguration strategies for each type. When interference is detected, the system can quickly identify the interference type and apply the appropriate pre-prepared compensation measures, reducing the time required for characterization and reconfiguration.
4Illumination intensity
If the system uses color light to create elaborate lighting atmospheres, then the illumination features can be enhanced with variable colour and temperature, but the perception of interference becomes more noticeable and disturbing
Solution Approach 1:
The monitoring system scans the rendered lighting scene and measures actual color and temperature parameters. By comparing these measurements against reference values, the system can detect even subtle color shifts or temperature deviations caused by interference, triggering reconfiguration to restore the intended atmospheric effect.

AI summary
The invention relates to the automatic rendering of a lighting scene with a lighting system, particularly the control of the rendering. A basic idea of the invention is to improve rendering of a lighting scene by automatically compensating interference, such as an alien light source or a dynamic perturbing event of a rendered lighting scene. An embodiment of the invention provides a light control system (10) for automatically rendering a lighting scene with a lighting system, wherein the light control (10) system is adapted for monitoring the rendered lighting scene for the occurrence of interference (14, 20, 22, 24), and automatically reconfiguring the lighting system such that a monitored occurrence of an interference is compensated (16, 18, 12). As result, the invention allows to prevent dynamic disturbances or unforeseen events, for example caused by faulty or alien light sources, from distorting the rendering of an intended lighting scene.
