摘要

The rapid development of greenhouse technology has attracted increased attention to research on greenhouse supplementary lighting. To improve performance of supplementary lighting system in lettuce greenhouses, this study uses the combination of blue and red light LEDs to design a new model of intelligent periodic supplementary lighting system for the lettuce greenhouse. Researchers used solar power to provide electricity for the system to improve energy efficiency. Results indicated that this system provides periodic supplementary lighting to the greenhouse, demonstrating a high degree of applicability and expandability.
