Bus Voltage Control for Illuminating Light Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to efficiently manage and optimize the power consumption of illuminating light loads connected to a bus, leading to suboptimal energy usage and inefficiencies, particularly in dynamic environments where the number of light loads or environmental conditions change.
Innovation Solution
A device comprising a controller and power detector that adjusts the direct current voltage signal on the bus by running a process to detect changes in total power consumption, informing the controller to redefine the voltage signal, thereby linking power consumption to voltage levels and optimizing energy use through feedback mechanisms from light loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of light loads or environmental conditions change, then the system must adapt to new conditions, but the power consumption optimization becomes suboptimal without re-running the selection process
Solution Approach 1:
The power detector continuously monitors the total power consumption of light loads and provides feedback to the controller. When a change in power consumption is detected, the controller re-runs the selection process to optimize the DC voltage signal, ensuring the system adapts to changing conditions while maintaining energy efficiency.
Solution Approach 2:
The system dynamically adjusts the DC voltage signal on the bus based on real-time detection of power consumption changes. The controller can re-execute the optimization process when needed, allowing the system to transition from static to dynamic operation to handle varying light load configurations and environmental conditions.
2Use of energy by moving object
If the controller continuously monitors and adjusts the DC voltage signal, then power consumption optimization is improved, but the system complexity increases
Solution Approach 1:
The system uses feedback from the power detector to trigger controller actions only when necessary. The controller monitors for changes in total power consumption and re-runs the optimization process selectively, rather than continuously, reducing unnecessary computational overhead while maintaining optimization effectiveness.
Solution Approach 2:
The power detector automatically detects changes in power consumption and triggers the controller to re-run the optimization process when needed. This self-service mechanism reduces the need for continuous manual monitoring and complex control logic, simplifying the overall system while maintaining optimization capabilities.

AI summary
Devices (1) for selecting settings for illuminating light loads (2, 3) connected to a bus (4) comprise controllers (11) for running processes and for defining, through controls of power converters (5, 6) connected to the bus (4), in response to process results, direct current voltage signals for the bus (4) and comprise power detectors (12) for detecting changes in total power consumptions of the illuminating light loads (2, 3) and for in response to detections of the changes informing the controllers (11) to run the processes again. This way, links are created between the total power consumption via the bus (4) and the direct current voltage signal on the bus (4), to save energy. The devices (1) may further comprise receivers (13) for receiving definitions of optimal individual voltage signals and/or of optimal individual power consumptions and/or of voltage amplitudes and may further comprise power meters (14) for measuring the total power consumption of the illuminating light loads (2, 3) for different direct current voltage signals for the bus (4).
