Engineering Contradiction Analysis
1Measurement precision
If a light detection structure with photoelectric conversion device, current conversion device, and control device is implemented, then measurement precision of ambient light brightness and color temperature is improved, but device complexity increases
Solution Approach 1:
The light detection structure is divided into three functional modules: photoelectric conversion device (with multiple photoelectric conversion elements for different wavelengths), current conversion device (with current conversion circuits), and control device (with processing circuits). This segmentation allows each module to specialize in specific tasks, improving overall measurement precision while managing complexity through modular design.
Solution Approach 2:
The photoelectric conversion device includes multiple photoelectric conversion elements that can detect different wavelengths of light (red, green, blue, and other wavelengths). This multi-functionality enables the system to measure both brightness and color temperature using a single integrated structure, improving measurement precision without proportionally increasing device complexity.
2Adaptability or versatility
If multiple photoelectric conversion elements detecting different wavelengths are used, then adaptability to various ambient light conditions is improved, but device complexity increases
Solution Approach 1:
The photoelectric conversion device is segmented into multiple photoelectric conversion elements, each sensitive to different wavelength ranges (red, green, blue, and other wavelengths). This segmentation enables the system to adapt to various ambient light conditions by selectively processing signals from different elements, improving environmental adaptability while maintaining manageable circuit complexity through modular architecture.
Solution Approach 2:
The system changes detection parameters by selecting different photoelectric conversion elements based on the ambient light conditions. The control device processes signals from different wavelength-sensitive elements to adapt to various lighting environments, improving versatility without requiring complex hardware changes.
