Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single dimmable power supply is used to power multiple LED luminaires, then the system complexity is reduced and cost is lowered, but performance differences become apparent in deep dimming scenarios causing unsynchronized on-off effects and uneven brightness levels
Solution Approach 1:
The patent applies local quality by assigning individual current regulation configuration information to each luminaire based on its specific performance characteristics. The dimmable power supply adjusts the dimming current differently for each luminaire according to its minimum ignition current and performance parameters, ensuring synchronized operation while maintaining individualized optimization for each device.
2Reliability
If individual current regulation configuration information is obtained and applied to each luminaire, then synchronized on-off effects and consistent brightness levels are achieved, but the system complexity and configuration requirements increase
Solution Approach 1:
The patent implements self-service by enabling the dimmable power supply to automatically obtain current regulation configuration information from each luminaire through communication interfaces. The system autonomously retrieves performance parameters such as minimum ignition current and automatically generates appropriate current regulation configurations without requiring manual intervention or complex external configuration processes.
Solution Approach 2:
The patent applies feedback by using communication modules to exchange information between the dimmable power supply and each luminaire. The power supply obtains performance characteristics from each luminaire and uses this feedback information to dynamically adjust the dimming current, creating a closed-loop control system that ensures synchronized operation and consistent brightness levels.
