By collecting parameters including input voltage, current, luminous flux and power factor of street lamps used for road lighting in Tianjin, we calculate the EEI to determine the energy efficiency level of the luminaires. This not only clarifies the lighting demand of luminaires in Tianjin’s road lighting scenarios, but also provides 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 the luminaires leave the factory, randomly select finished street lamps intended for road lighting in Tianjin, and collect parameters such as their input voltage, current, luminous flux and power factor. 2. Data Processing (1) Energy Efficiency Index (EEI) Analysis for Luminaires Based on Collected Parameters: EEI = (I×V)×PF / Pref; where 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 = 0.07341×Φ_use. (2) Energy Efficiency Level Classification: 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 analysis before the luminaire leaves the factory can ensure the luminaires meet the lighting requirements in Tianjin’s road lighting application scenarios. Meanwhile, it can also provide data support for manufacturers to optimize luminaire design schemes, improving the energy-saving performance and service life of the luminaires.
