Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If solid state light source arrays are used to control color temperature and luminous intensity, then energy efficiency and longevity are improved, but flexibility and precision in simulating natural daylight are worsened
Solution Approach 1:
The lighting system is divided into multiple solid state light source arrays, each capable of independent control. Each array contains multiple solid state light source modules that can be individually adjusted, allowing precise control over color temperature and luminous intensity to simulate natural daylight variations throughout the day while maintaining energy efficiency.
Solution Approach 2:
The system implements dynamic control of color temperature and luminous intensity through a control module that receives CCT signals and dimmer signals. This allows the lighting system to adapt and change characteristics in real-time, simulating the dynamic nature of natural daylight while maintaining the energy efficiency of solid state light sources.
2Adaptability or versatility
If multiple solid state light source modules with different CCTs are combined, then adaptability in color temperature tuning is improved, but device complexity is worsened
Solution Approach 1:
The control module is designed with multi-functionality to handle various control scenarios. It can process CCT signals to adjust color temperature and dimmer signals to adjust luminous intensity, and it includes a color control algorithm to manage the mixing of multiple light source modules with different CCTs. This universal control approach simplifies the user interface while maintaining wide color temperature tuning capability.
Solution Approach 2:
The system controls the output of each solid state light source module by changing electrical parameters (current levels) rather than physically reconfiguring the hardware. The control module adjusts the drive current to each module based on the desired CCT and luminous intensity, allowing flexible parameter tuning without increasing physical device complexity.
3Measurement precision
If a control module with color control algorithm is implemented, then precision in CCT and luminous intensity control is improved, but device complexity is worsened
Solution Approach 1:
The control module serves as an intermediary between the user interface and the solid state light source arrays. It contains a color control algorithm that processes CCT signals and dimmer signals to calculate the appropriate drive currents for each light source module. This intermediary layer provides precise control while keeping the individual light source modules simple and the user interface straightforward.
Solution Approach 2:
The system replaces complex mechanical or manual adjustment mechanisms with electronic control. The color control algorithm uses mathematical calculations and electrical signal processing to achieve precise CCT and luminous intensity control, substituting what would otherwise require complex mechanical tuning systems.
