Multi-Spectrum Luminaire Control for Plant Growth
Solution Overview
Problem
Current plant growth lighting devices are complex and costly, with low utilization flexibility and efficiency due to the integration of multiple spectral demands throughout a plant's growth cycle, particularly for special wave bands, which complicates the control circuit and increases costs.
Innovation Solution
A multi-spectrum generating device comprising at least one first luminaire and one second luminaire, each with a light source, where the luminaires are independently controlled by different power sources to achieve multiple spectra, allowing for flexible control and high utilization rate without affecting primary spectral demands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple spectral demands throughout the growth cycle are integrated into the same plant growth lighting device, then the device can provide multiple spectra, but the control circuit becomes complex and the overall cost increases
Solution Approach 1:
The patent divides the lighting system into multiple independent luminaires, each equipped with its own control circuit. This segmentation allows each luminaire to be controlled separately, providing multi-spectrum capability while keeping individual control circuits simple and manageable, thus resolving the contradiction between versatility and complexity
Solution Approach 2:
Each luminaire is designed to be multi-functional, capable of providing different spectra (including special wave bands like infrared and ultraviolet) through independent control. This universal design allows a single luminaire to serve multiple spectral needs throughout the plant growth cycle, achieving adaptability without requiring a completely separate system for each spectrum
2Adaptability or versatility
If multiple spectral demands throughout the growth cycle are integrated into the same plant growth lighting device, then the device can provide multiple spectra, but the overall cost of the device is relatively higher
Solution Approach 1:
By segmenting the system into multiple independent luminaires with separate control circuits, the patent enables modular manufacturing and deployment. Users can start with basic luminaires and add special wave band luminaires only when needed, reducing overall device cost while maintaining the capability for multi-spectrum operation
Solution Approach 2:
The patent treats special wave band luminaires as optional, add-on components rather than integral parts of the base system. This approach allows users to forgo expensive special wave band capabilities when not needed, and only incorporate them temporarily for specific research or growth requirements, thereby reducing overall device cost
3Adaptability or versatility
If special wave bands are integrated into the same device with primary spectral demands, then the device can provide all required spectra, but the utilization rate of special wave bands is low
Solution Approach 1:
The patent separates special wave band luminaires from primary spectrum luminaires into independent, controllable units. This segmentation enables selective activation of special wave bands only during specific growth stages or for specific research needs, ensuring high utilization rates by avoiding continuous operation when not required
Solution Approach 2:
The independent control architecture enables periodic or intermittent activation of special wave band luminaires based on specific research requirements or plant growth stages. This periodic action pattern ensures that special wave bands are used intensively when needed and completely deactivated when not needed, maximizing utilization rate while maintaining spectral coverage capability
4Adaptability or versatility
If multiple spectral demands are integrated into the same device, then the device can meet all spectral requirements, but the utilization flexibility is low
Solution Approach 1:
The patent divides the lighting system into independently controllable luminaires, each with its own control circuit. This segmentation provides high utilization flexibility by allowing users to independently switch on/off and adjust each luminaire based on specific research needs or growth stages, while still maintaining comprehensive spectral coverage capability
Solution Approach 2:
The independent control architecture creates a dynamic system where each luminaire can be individually adjusted in real-time based on changing research requirements or plant growth stages. This dynamic control capability significantly enhances utilization flexibility compared to integrated systems with fixed or centrally-controlled spectral output

AI summary
A multi-spectrum generating device and method thereof. The multi-spectrum generating device includes at least one first luminaire, at least one second luminaire, and a control component. The first luminaire and the second luminaire each have a light source. The control component is connected to the first luminaire and the second luminaire for controlling the first luminaire and the second luminaire. In the present application, by controlling the switches of the first luminaire and the second luminaire, the multi-spectrum can be realized, so as to meet some special requirements of photobiological regulation. Moreover, the first luminaire and the second luminaire are mutually independently controlled luminaires and are controlled by different power sources, so the control circuit is simple and has a low cost, without affecting the primary demanded spectra provided by the first luminaire. Therefore, the present application has high utilization rate and high flexibility in use.
