Scope

Main technical content: This standard specifies the energy efficiency grading, testing methods, evaluation requirements, and management norms for vertical farming lighting systems, applicable to all types of enclosed or semi-enclosed vertical farming production environments with electrical lighting systems. Specific application scenarios include but are not limited to the following: (1) Applicable system types - LED plant growth lighting systems: wavelength range 400-700nm, photon flux density (PPFD) adjustment range 100-1000μmol/m2/s, system power covering 50W-5000W. - High-pressure sodium lamps (HPS): power specifications 150W-1000W, luminous efficiency ≥ 110lm/W. - Fluorescent lighting systems: color rendering index (CRI) ≥ 82, color temperature range 2700K-6500K. - Composite spectral systems: mixed lighting systems containing at least two light sources, with photosynthetically active radiation (PAR) accounting for ≥ 85%. (2) Applicable cultivation scenarios - Leafy vegetable factories: short-cycle crops such as lettuce and spinach, requiring 200-400μmol/m2/s of light. - Multi-layer fruit and vegetable cultivation: tomatoes, cucumbers, etc., requiring 400-800μmol/m2/s of light. - Medicinal plant cultivation: lighting cycle of 12-18 hours/day, with spectral requirements meeting specific active ingredient accumulation requirements. - Tissue culture seedling production: light intensity requirement 50-200μmol/m2/s, requiring precise control of blue light (450nm) and red light (660nm) ratios. (3) Core evaluation indicators - Photoelectric conversion efficiency: photosynthetic photon flux efficiency (PPE): Level 1 ≥ 2.2μmol/J, Level 2 ≥ 1.8μmol/J, Level 3 ≥ 1.5μmol/J. - System comprehensive energy efficiency (η): Level 1 ≥ 0.90, Level 2 ≥ 0.85, Level 3 ≥ 0.80. - Power factor: Level 1 ≥ 0.98, Level 2 ≥ 0.95, Level 3 ≥ 0.92. - Spectral performance: spectral matching (with target crop spectral requirements): Level 1 ≥ 85%, Level 2 ≥ 80%, L
