Lighting Controller Scene Blending via Initial State Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting systems, primarily designed for professional environments, fail to meet the diverse and nuanced lighting needs of home users, particularly in terms of scene-based control and integration with presence sensors, leading to unintended disruption of pre-set lighting scenarios.
Innovation Solution
A lighting system controller that receives trigger signals and adjusts light output based on the initial state of one or more lighting devices, using a processor to generate control data that considers the predetermined range or functions relative to the initial light output, allowing for seamless integration with scene settings and reverting to original states after triggers expire.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a presence sensor triggers a lighting device to emit bright white light for functional lighting, then the lighting device provides adequate illumination for work and navigation, but the trigger signal ruins pre-set scene settings such as romantic light scenes
Solution Approach 1:
The lighting system dynamically adjusts its behavior based on the current state. When a trigger signal is received, the controller checks whether lighting devices are in a scene setting mode or functional mode, and adapts the light output accordingly - preserving scene settings when appropriate while providing functional lighting when needed
Solution Approach 2:
The system changes the parameters of light output (intensity, color temperature, hue) based on the detected initial state. If devices are in a scene setting, the trigger signal modifies the scene parameters rather than overriding them with fixed functional lighting parameters, thereby maintaining both functionality and scene ambiance
2Extent of automation
If professional lighting system logic is applied to home lighting systems, then automated control features are implemented, but the user experience is profoundly impacted due to different lighting needs
Solution Approach 1:
The system applies different control logic to different lighting devices based on their individual states and the context of scene settings. Rather than applying uniform professional lighting logic to all devices, the controller adapts the automation behavior locally to each device's current function - preserving scene ambiance for atmospheric lighting while providing functional control for task lighting
3Device complexity
If trigger-based control is implemented without considering initial light output, then simple control logic is maintained, but the system cannot preserve pre-set scenes or provide context-aware lighting
Solution Approach 1:
The controller performs a preliminary check of the initial light output state of lighting devices before applying trigger-based control. By detecting whether devices are in scene settings or functional modes beforehand, the system can selectively apply different control strategies, thereby maintaining scene integrity while enabling appropriate automated responses

AI summary
A lighting system controller, a lighting system control method and software program product are provided for controlling a lighting device based on a trigger signal, such as a presence detection signal from a presence sensor. Instead of switching the lighting device to a fixed light setting at all times when the trigger signal is received, the initial light output of the lighting device is determined. The lighting device is then controlled according to a fixed light setting (e.g. white light at full brightness) if the determined initial light output is within a predetermined range, and else it is controlled according to a function relative to the determined initial light output. For example, if the lighting device is participating in a romantic scene emitting predominantly red light the lighting device may switch to reddish white light instead of the full white light and/or the brightness level of the light is lowered compared to the fixed light setting.
