Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If traditional LED fixtures are used, then energy efficiency and lifespan are improved, but light intensity and spectral breadth cannot match incandescent and fluorescent lighting
Solution Approach 1:
The lighting system is divided into multiple individual LED modules, each containing its own heat sink, LED array, and lens assembly. This segmentation allows each module to be optimized independently for specific wavelength ranges while collectively providing full-spectrum coverage and high intensity suitable for horticultural applications
Solution Approach 2:
Multiple LED modules emitting different wavelengths (blue, red, green, yellow) are combined in a single fixture to create a broad-spectrum light source. The modules are positioned and angled to overlap their light beams, merging their individual spectra to achieve full-spectrum illumination that matches natural sunlight
2Illumination intensity
If LED modules are arranged to produce concentrated illumination, then light intensity at a specific distance is improved, but the complexity of optical design increases
Solution Approach 1:
Each LED module incorporates a lens with a specific radius of curvature that focuses light from the LED array into a concentrated beam. The curved lens surface refracts light rays to converge at a predetermined distance, creating an illuminated spot that is both intense and precisely positioned without requiring complex multi-element optical systems
Solution Approach 2:
Each LED module is designed with locally optimized optical properties - the lens curvature, LED array configuration, and heat sink geometry are specifically tailored to produce the desired light distribution pattern for that module's position in the fixture, simplifying the overall design by making each component self-optimizing
