Innovation Solution
A lighting adjustment system comprising a light sensor, a personnel controller, a central processing unit, and a lighting device, where the light sensor monitors illuminance and color temperature and transmits data to the central processing unit, which adjusts the lighting device's beam angle, color temperature, and illuminance in real-time based on user selections and monitored data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing lighting control technology adjusts only illuminance and color temperature, then the system is simple to operate, but it cannot meet the requirements of creating an indoor environment with healthy dynamic non-visual light
Solution Approach 1:
The patent segments the lighting control system into multiple independent modules: a light sensor module for monitoring, a central processing unit for computation, and a lighting device for execution. Each module handles specific functions (illuminance detection, color temperature detection, parameter calculation, lighting adjustment), allowing the system to manage complex multi-parameter control through divided responsibilities while maintaining operational simplicity
Solution Approach 2:
The system dynamically adjusts lighting parameters (illuminance, color temperature, spectral power distribution) based on real-time monitoring data and time-of-day variations. The central processing unit continuously receives sensor data, calculates optimal parameters considering circadian rhythm requirements, and updates the lighting device accordingly, enabling the system to adapt to changing environmental and physiological conditions
2Measurement precision
If lighting control system monitors multiple parameters including spectral power distribution, then the lighting environment optimization is improved, but the measurement and control difficulty increases
Solution Approach 1:
The patent introduces a central processing unit as an intermediary between the light sensor and lighting device. This intermediary receives raw measurement data from sensors, performs complex calculations to determine optimal lighting parameters based on circadian rhythm models, and translates these into control signals for the lighting device. This mediator handles the measurement complexity centrally while keeping individual sensor and actuator components relatively simple
Solution Approach 2:
The system replaces complex mechanical measurement and adjustment mechanisms with electronic and optical solutions. Instead of mechanical filters or moving parts for spectral control, the patent uses electronic sensors to detect spectral power distribution and electronic dimming circuits to adjust lighting parameters, significantly reducing mechanical complexity while improving measurement precision
3Reliability
If the system adjusts lighting parameters in real-time based on monitoring information, then the non-visual health effects are improved, but the energy consumption increases
Solution Approach 1:
The system implements periodic adjustment of lighting parameters aligned with circadian rhythm cycles rather than continuous random adjustments. The central processing unit receives time information, determines the current circadian phase, and adjusts lighting parameters accordingly at appropriate intervals. This periodic action ensures health benefits are maintained while avoiding unnecessary energy consumption from constant adjustments
Solution Approach 2:
The system uses feedback from light sensors to monitor actual lighting conditions and compares them with target parameters calculated based on circadian rhythm requirements. The central processing unit receives this feedback, determines whether adjustments are needed, and only activates the lighting device when parameter changes are required. This feedback mechanism ensures energy is consumed only when necessary to maintain optimal lighting for health benefits
