Horticulture Lighting Interface for Spectral Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current horticulture lighting systems struggle to control the spectral composition of light effectively, limiting the ability to provide optimal lighting conditions for plant growth, as they rely on detailed technical information about the installed lighting devices and their positions, and are not energy efficient.
Innovation Solution
The introduction of a horticulture action space, represented by dimensions for photosynthesis, phototropine, phytochrome Pr, and phytochrome Pfr actions, allows for the conversion of desired physiological plant responses into control instructions for lighting systems, enabling dynamic spectral control and energy optimization by mapping set points to target points within this space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional horticulture lighting control systems are used, then detailed technical information about lighting devices and their positions is required, but this increases system complexity and makes control difficult
Solution Approach 1:
The patent introduces a horticulture action space as an intermediary coordinate system that mediates between the lighting system and plant physiological responses. This action space with dimensions for photosynthesis, phototropism, and phytochrome actions serves as a universal interface, eliminating the need for detailed device-specific information while simplifying control operations.
2Adaptability or versatility
If conventional lighting control methods are used, then control is tied to specific lighting device technologies, but this reduces adaptability to different lighting systems
Solution Approach 1:
The horticulture action space provides a universal coordinate system that can interface with any lighting system regardless of technology type. The same action space coordinates can control different lighting devices (LED, HPS, fluorescent), making the control system universally applicable while maintaining simplicity through the standardized multi-dimensional framework.
3Use of energy by moving object
If traditional lighting control is used, then energy efficiency is limited, but achieving optimal spectral control would require complex systems
Solution Approach 1:
The patent controls lighting by adjusting parameters in the horticulture action space (photosynthesis action, phototropine action, phytochrome Pr action, phytochrome Pfr action) rather than directly manipulating device-specific parameters. This parameter-based approach enables energy optimization by targeting plant physiological responses directly, achieving spectral control efficiency without complex device-level adjustments.
