Different scenarios have distinct lighting requirements for luminaires, such as requirements for their energy efficiency ratings. By collecting parameters including input voltage, current, luminous flux, and power factor of LED street lamps intended for Lima parking lots, and calculating the Energy Efficiency Index (EEI) to determine the energy efficiency rating of the luminaires, we can clarify the lighting requirements for these parking lots, and provide data support for manufacturers to optimize luminaire design schemes, thereby improving the energy-saving performance and service life of the luminaires. 1. Data Source: Before leaving the factory, finished LED street lamps dedicated to Lima parking lots are randomly sampled, and parameters such as input voltage, current, luminous flux, and power factor of these street lamps are collected. 2. Data Processing (1) Energy efficiency grade EEI analysis of the luminaire based on the collected parameters: EEI = P * PF / Pref = IV * PF / Pref; where P is the rated power of the luminaire, PF is the power factor, Pref is the reference power of the luminaire, and Φ_use is the effective luminous flux of the luminaire. When Φ_use < 1300 lm: Pref = 0.88√Φ_use + 0.049 Φ_use When Φ_use ≥ 1300 lm: Pref = 0.07341Φ_use (2) Energy efficiency grading standards: If EEI ≤ 0.11, it is grade A++; if 0.11 ≤ EEI ≤ 0.17, it is grade A+; if 0.17 ≤ EEI ≤ 0.24, it is grade A; if 0.24 ≤ EEI ≤ 0.6, it is grade B; if 0.6 ≤ EEI ≤ 0.8, it is grade C; if 0.8 ≤ EEI ≤ 0.95, it is grade D; if EEI > 0.95, it is grade E. 3. Data Application: The energy efficiency index is one of the important indicators for evaluating luminaire energy efficiency. Conducting EEI-based analysis on luminaires before they leave the factory enables them to meet the lighting requirements of Lima parking lot scenarios. Meanwhile, it can provide data support for manufacturers to optimize luminaire design schemes, thereby improving the energy-saving performance and service life of the luminaires.
