Lighting Control System Merging Dynamic Scenes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting control systems face issues when a dynamic light scene is overruled by a newly activated light scene, leading to undesired behavior, such as sudden changes in lighting that may disrupt intended lighting effects.
Innovation Solution
A method is introduced to generate a modified light scene by combining the dynamic light scene and the newly activated light scene, taking into account the intensity changes of both scenes. This ensures that the dynamic effects of the original light scene are preserved while incorporating changes from the new light scene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a newly activated light scene overrules the currently active dynamic light scene, then the new light scene settings are immediately applied, but the dynamic effects of the original light scene are lost resulting in abrupt lighting changes
Solution Approach 1:
The patent combines the new light scene settings with the ongoing dynamic light scene by integrating the new color/position settings while preserving the dynamic intensity transitions. The control system merges the static parameters from the new light scene with the dynamic parameters from the current scene, creating a hybrid light scene that maintains both the user's new settings and the smooth dynamic effects.
Solution Approach 2:
The patent applies preliminary action by pre-calculating the modified light scene parameters before actually switching scenes. The system determines in advance how the new light scene settings will interact with the ongoing dynamic scene, preparing the transition parameters to ensure smooth continuity rather than abrupt changes.
2Ease of operation
If a dynamic light scene is actively controlling lighting intensity changes, then smooth transitions are achieved, but sudden user-selected light scenes cause abrupt interruptions of these transitions
Solution Approach 1:
The patent applies dynamics by making the light scene switching behavior adaptive rather than rigid. When a user selects a new light scene during an active dynamic scene, the system dynamically adjusts the transition behavior based on the current state of the dynamic scene, allowing the lighting to continue evolving smoothly while incorporating the user's new settings rather than abruptly interrupting the dynamic effects.
3Speed
If the system immediately applies a newly selected light scene, then user input responsiveness is high, but the characteristics of the dynamic light scene are lost
Solution Approach 1:
The system performs preliminary action by pre-processing the new light scene settings to determine how they will be integrated with the ongoing dynamic scene. This includes calculating modified parameters that preserve dynamic characteristics while incorporating new settings, so that when the scene activation occurs, the transition is already optimized to maintain smooth dynamics rather than causing abrupt changes.
