Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional artificial light sources (incandescent lamp, halogen lamp, high-pressure sodium lamp) are used for cultivation, then illumination is provided, but heat radiation causes overheating and suboptimal growth conditions
Solution Approach 1:
The light source is segmented into multiple LED chips with different emission wavelengths (first group: 300-430nm, second group: 450-490nm, third group: 550-570nm, fourth group: 600-650nm). Each wavelength group targets specific photoreceptors in aquatic organisms, providing spectrally optimized illumination without the broad-spectrum heat radiation of conventional sources.
Solution Approach 2:
The invention changes the spectral parameters by using LEDs with specific peak wavelengths and intensity ratios (first group: 0.5-0.9, second group: 1.0, third group: 0.1-0.8, fourth group: 0-0.5). This parameter optimization provides effective illumination while minimizing heat radiation, as LEDs convert electrical energy directly to light with high efficiency and low thermal output.
2Illumination intensity
If conventional artificial light sources are used, then illumination is provided, but the spectrum does not match natural sunlight underwater, leading to suboptimal growth
Solution Approach 1:
The invention copies the natural sunlight spectrum underwater by using LED chips that emit at specific wavelengths corresponding to the spectral composition of natural sunlight at various depths. The four groups of emission peaks replicate the characteristic spectral distribution, providing illumination that matches the natural environment and ensures optimal growth conditions for aquatic organisms.
3Illumination intensity
If current sunlight-simulating light sources are used, then terrestrial sunlight spectrum is replicated, but the spectrum does not match underwater sunlight, resulting in inadequate illumination for aquatic organisms
Solution Approach 1:
The invention applies local quality by providing different spectral compositions for different underwater depths. The LED array can be configured with specific wavelength intensities to match the spectral characteristics of sunlight at various depths (shallow, medium, deep water), making the light source adaptable to different aquatic environments and organism requirements.

AI summary
A light source module includes a wiring board and a LED array electrically connected to the wiring board. The LED array can be driven to emit a first group of emission peaks in 300 nm≤λmax<450 nm, a second group of emission peaks in 450 nm≤λmax<550 nm, and a third group of emission peaks in 550 nm for matching the spectrum of sunlight underwater. When the maximum peak intensity of the emission peaks in the second group is taken as 1.0, the peak intensity Ia of each emission peak in the first group is in a range of 0<Ia≤0.9, and the peak intensity Ib of each emission peak in the third group is in a range of 0<Ib≤0.9. Accordingly, the light source module is suitable for aquatic species and can enhance growing rate of the aquatic species.
