At the end of 2024, a national standard entitled "Technical Specification for Light Environment of Artificial Light Plant Factory" (GB/T 45177-2024) was officially released and scheduled to be implemented on July 1, 2025. This marks a crucial step forward for China in leading cutting-edge smart agriculture and promoting the standardization of the plant lighting industry.
I. Filling the Gap: Setting a Scientific Benchmark for "Vertical Agriculture"
This standard aims to address the core pain points in the industry's development. Currently, fully artificial light-based plant factories and supplemental lighting greenhouses are in a phase of rapid development, but the design and evaluation of their core "light environment" have long lacked unified standards. Different manufacturers and users have different understandings of light quality and light quantity, which hinders technological progress and market trust.
This newly released national standard is a systematic response to this key application scenario. Specifically targeting plant cultivation areas, it specifies general requirements for the light environment, core photon irradiance and energy efficiency-related power density technical indicators, and provides standardized test methods. This provides an objective and scientific basis for engineering design, equipment selection, and operational evaluation, and will effectively guide the industry away from extensive management and towards refined management. .
II. System Construction: Comprehensive Coverage from Terminology and Products to Scenarios
It is worth noting that this standard does not exist in isolation. Together with the two national standards released at the same time, namely "Terminology for Plant Lighting" and "Performance Specifications for LED Lamps, LED Fixtures and LED Modules for Plant Lighting," it constitutes a complete specification system covering basic definitions, core products, and final application scenarios. This systematic approach clearly reflects the national strategic intent to promote the standardization of smart agriculture from a top-level design perspective, laying a solid foundation for the healthy and orderly development of the industry. .
III. Internal and External Collaboration: From "Chinese Standards" to "International Voices"
More significantly, the maturation of domestic standards is closely linked to the internationalization process. Chinese experts are actively leading the development of several international standards, including the "Glossary of Plant Lighting Terminology." The early implementation of domestic standards will not only rapidly improve the technological level and product quality of domestic industries, but also secure valuable influence for China in the field of international agricultural lighting standards, achieving coordinated progress in domestic and international standardization efforts. .
In conclusion, the implementation of the "Technical Specifications for Light Environment of Artificial Light Plant Factories" will act like a precise and controllable spectrum, illuminating the path to high-quality development of plant factories and helping China to take a leading position in the integration and innovation of modern agriculture and optoelectronic technology.
