Horticulture Lighting Terminology

1 Scope

GB/T 44941-2024 is the Chinese vocabulary of horticultural lighting. Plant lighting is measured in quantities that ordinary lighting is not: the photon flux in the photosynthetically active band rather than the lumen, the daily light integral rather than the illuminance, and the spectral distribution in terms of what the plant's photoreceptors respond to rather than what the human eye does, so a vocabulary built on photometry is actively misleading here. China manufactures most of the world's horticultural LED and operates a very large greenhouse and vertical farm sector. The standard defines the terms: the radiometric and photon quantities and their units, the spectral terms including the photosynthetic and morphogenic wavebands, the lighting system and luminaire terms, the terms describing the lighting strategy, supplemental, photoperiodic and sole-source, the plant response terms, and the measurement and performance terms by which a horticultural luminaire is rated. It took effect on 28 November 2024.

This document defines the application of light in plant lighting, radiation (band) and (radiation) amount, radiation sources and facility applications, and plant related light radiation. Terms and definitions related to plant physiology. This document applies to the field of plant lighting.
