Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current light systems for aquatic photosynthetic organisms, such as microalgae, fail to accurately replicate natural sea light conditions due to limitations in simulating light intensity and spectrum variations, which are crucial for growth and ecophysiological states, and existing systems are often bulky, energy-intensive, and lack versatility.
Innovation Solution
A light system utilizing Z-POWER LED-RGB technology that emits a wide range of visible light spectrum (400-700 nm) by combining red, green, and blue colors, allowing for adjustable intensity and temporal variability, simulating natural light conditions in different aquatic environments, and is designed to be energy-efficient and modular.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If neon systems are used for algal growth illumination, then the system is simple to operate, but the light spectrum is different from marine environment (high red presence), light intensity is low, the system is bulky, energy consumption is medium with high heat supply, and light intensity is not adjustable
Solution Approach 1:
The patent combines multiple LED types (blue, red, green) into a single illumination system, merging their spectral outputs to create a comprehensive light spectrum that matches marine environments. This allows the system to overcome the spectral limitations of individual neon lamps while maintaining ease of operation through integrated control.
Solution Approach 2:
The LED-based system serves multiple functions: it provides adjustable spectrum composition, variable light intensity, and controllable temporal patterns. This multi-functionality replaces the fixed characteristics of neon systems, allowing adaptation to different marine environments and experimental requirements while remaining simple to operate through centralized control.
2Adaptability or versatility
If discharge lamps are used for aquarium illumination, then the spectrum may be more appropriate to deep marine ecosystem, but the lamps cause heating of the environment, have fixed spectrum, impossibility to vary frequency, high energy consumption, and limited duration of life
Solution Approach 1:
The patent replaces traditional discharge lamp mechanisms with LED technology, substituting the mechanical/electrical arc discharge system with electroluminescence. This substitution maintains the ability to produce appropriate spectra for marine environments while dramatically reducing energy consumption and eliminating the heating problems associated with discharge lamps.
Solution Approach 2:
The LED system introduces dynamic control over light frequency and intensity, allowing the spectrum to be varied and adjusted according to different marine environments and experimental needs. This contrasts with the fixed spectrum of discharge lamps while maintaining spectral appropriateness through programmable LED combinations.
3Illumination intensity
If LED systems with blue, red and green colors are used, then the light appears white to human eye, but the system does not allow to vary the colors separately with the same device
Solution Approach 1:
The patent segments the white light source into separate controllable LED components (blue, red, green). Each color channel can be independently controlled through dedicated control circuits, allowing the system to vary colors separately while maintaining the ability to produce white light when all channels are activated together. This segmentation enables precise spectral manipulation for different experimental conditions.
