Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If traditional LED fixtures are used, then energy efficiency is improved, but luminous output and spectrum breadth are insufficient
Solution Approach 1:
The fixture divides the lighting system into multiple independent LED modules, each containing specific wavelength-emitting LEDs (blue, cyan, green, yellow-green, yellow, orange, red). This segmentation allows optimization of each module's spectral output while maintaining overall energy efficiency, achieving both high luminous output and broad spectrum coverage.
Solution Approach 2:
The patent combines multiple LED types with different spectral characteristics in a single fixture, creating a composite lighting system. Each LED type contributes specific wavelengths, and their combined output achieves a broad spectrum (400-700nm) while maintaining LED energy efficiency, resolving the contradiction between energy efficiency and luminous output.
2Use of energy by moving object
If traditional LED fixtures are used, then energy efficiency is improved, but spectrum breadth is insufficient
Solution Approach 1:
The lighting system is segmented into multiple LED modules, each responsible for specific wavelength ranges. This allows independent optimization of spectral output in each module while maintaining the energy efficiency of individual LEDs, achieving broad spectrum coverage (400-700nm) without sacrificing energy efficiency.
Solution Approach 2:
The fixture is designed to provide multiple functions simultaneously: it delivers high luminous output, broad spectrum coverage (400-700nm), and maintains LED energy efficiency. The multi-functional design allows the system to meet diverse horticultural lighting requirements while preserving energy advantages.
3Illumination intensity
If multiple LED modules are added to increase luminous output, then illumination intensity is improved, but device complexity increases
Solution Approach 1:
The fixture uses seven distinct LED modules, each emitting at specific wavelengths. This segmentation allows systematic organization of complex components, making the system manageable despite having multiple modules. Each module's specialized function simplifies the overall control and maintenance compared to a monolithic design.
Solution Approach 2:
Each LED module is designed with specific local qualities - particular wavelength emissions, targeted beam angles, and specialized lenses. This local optimization allows the system to achieve high overall luminous output while keeping individual modules relatively simple and standardized, reducing overall system complexity.

AI summary
A modular lighting fixture includes a housing having a front panel, the front panel having a radius of curvature, and a plurality of LED modules disposed adjacent the front panel, each LED module having a heat sink, an LED source mounted to the heat sink, and a lens disposed over the LED source, the lens capable of refracting light emitted by the LED source into a desired distribution pattern. The plurality of LED modules produce a concentrated illuminated area at a pre-determined distance from the front panel as determined by the radius of curvature of the front panel.
