Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If filter devices are used to filter out specific spectral ranges to mitigate sensitivity issues in species, then the sensitivity impacts on species are reduced, but the radiation capacity is reduced
Solution Approach 1:
Instead of filtering out harmful spectral ranges from a broad spectrum source, the invention inverts the approach by selectively generating only the desired spectral ranges using multiple LEDs with different dominant wavelengths. This avoids the need for filtering while maintaining radiation capacity in the useful spectral ranges.
Solution Approach 2:
The invention segments the light source into multiple LED components, each emitting in a specific spectral range. By arranging LEDs with different dominant wavelengths (e.g., blue, green, red) in specific patterns, the system generates a tailored spectrum that avoids harmful ranges while maintaining useful radiation capacity.
2Object-affected harmful factors
If filter devices are arranged in luminaire housing to influence light spectrum, then spectral ranges are filtered out, but additional installations and device complexity are required
Solution Approach 1:
The invention extracts the spectral control function from separate filter devices and integrates it directly into the LED light source. By selecting specific LED wavelengths and arrangements, the desired spectral filtering effect is achieved inherently by the light generation process itself, eliminating the need for additional filter components.
Solution Approach 2:
The LED array serves multiple functions simultaneously: it provides illumination while also performing spectral filtering by selective emission. The same LED components that generate light also define the spectral characteristics, combining the functions of light source and spectral filter in a single system.
3Ease of manufacture
If multiple LEDs with different colors are arranged to emit specific spectral ranges, then color rendering is enhanced, but the number of LED components and arrangement complexity increases
Solution Approach 1:
The invention applies local quality by assigning specific dominant wavelengths to specific LED locations in the array. Each LED position is optimized for its particular wavelength, and the spatial arrangement of different colored LEDs creates the desired spectral distribution while maintaining manufacturability through standardized mounting patterns.
