Engineering Contradiction Analysis
1Adaptability or versatility
If conventional illumination devices use fixed light distribution control, then the structure is simple, but the ability to create psychological comfort effects like natural light fluctuations is lost
Solution Approach 1:
The patent implements dynamic light distribution control by enabling the optical element to change its light distribution characteristics over time according to 1/f fluctuation patterns. The processing circuit dynamically adjusts the light distribution state between different directions, creating natural-looking fluctuations that provide psychological comfort while maintaining manageable system complexity through efficient control algorithms.
2Illumination intensity
If dynamic light distribution control is implemented, then psychological comfort effect is achieved, but control processing complexity increases
Solution Approach 1:
The patent changes the control parameter from static light distribution values to dynamic 1/f fluctuation patterns. The processing circuit generates control signals that vary over time according to 1/f noise characteristics, allowing the light distribution state to naturally fluctuate between different directions. This approach achieves psychological comfort effects while keeping the processing circuit complexity manageable by using well-established 1/f noise generation techniques.
