Engineering Contradiction Analysis
1Adaptability or versatility
If lamps capable of changing light emitting characteristics are manufactured, then color temperature control for health benefits can be achieved, but the cost becomes too high for widespread adoption
Solution Approach 1:
The patent divides the lighting system into multiple independent LED modules, each containing LEDs with different color temperatures (e.g., warm white, neutral white, cool white). This segmentation allows selective activation of specific modules based on desired color temperature, providing adaptability while keeping individual module costs manageable and simplifying manufacturing.
Solution Approach 2:
The patent combines multiple LED modules with different color temperature characteristics into a single integrated lighting apparatus. By merging these modules and controlling them through a unified driving circuit, the system achieves versatile color temperature adjustment capabilities while maintaining cost-effectiveness through shared control infrastructure.
2Adaptability or versatility
If multiple LED modules with different color temperatures are used, then spectral characteristics can be adjusted, but the device complexity increases
Solution Approach 1:
The driving circuit is designed with multi-functionality to control multiple LED modules with different color temperatures. A single driving circuit implements various functions including current regulation, dimming control, and color temperature adjustment by selectively activating different LED modules, thereby reducing overall system complexity despite having multiple modules.
Solution Approach 2:
The system dynamically adjusts the activation and current distribution to multiple LED modules based on control signals. The driving circuit can dynamically switch between different LED modules or combine them in various ratios to achieve desired spectral characteristics, providing adaptability without requiring separate dedicated control circuits for each module.
