Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor lighting control systems for public places lack flexibility in adjusting lighting intensity and characteristics, leading to high energy consumption and unnecessary costs, while advanced systems often incur excessive complexity and reliability issues.
Innovation Solution
A driver apparatus that monitors active periods of operating power, selects lighting programs based on observed durations, and controls the provision of power to light sources, allowing for adjustable lighting characteristics such as intensity and color, without requiring significant changes to existing infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If simple dimming systems are used, then energy consumption is reduced, but flexibility and adjustability of lighting characteristics are lost
Solution Approach 1:
The driver apparatus dynamically adjusts lighting parameters (intensity, color temperature) in real-time based on observed active period durations, transitioning from static simple dimming to adaptive dynamic control that optimizes energy consumption while maintaining flexibility
Solution Approach 2:
The system observes the duration of active periods and uses this feedback information to automatically select appropriate lighting programs, enabling the lighting system to adapt its characteristics based on actual usage patterns without requiring complex external control infrastructure
2Adaptability or versatility
If advanced control systems with PLC or wireless connections are used, then lighting control flexibility is improved, but system complexity and cost increase
Solution Approach 1:
The driver apparatus autonomously observes active period durations and automatically selects lighting programs without requiring external control signals or communication infrastructure, enabling the system to serve itself and eliminate complex control wiring
Solution Approach 2:
The driver apparatus performs multiple functions including power conversion, lighting program selection, and lighting parameter control within a single integrated device, eliminating the need for separate control systems and reducing overall system complexity
3Adaptability or versatility
If advanced control systems are used, then lighting control flexibility is improved, but reliability decreases due to more components
Solution Approach 1:
The invention extracts the control functionality from external complex control systems and integrates it directly into the driver apparatus, eliminating relays, control cables, and external controllers that would reduce reliability
