Different scenarios have distinct lighting requirements for luminaires, among which energy efficiency grade requirements are typical. By collecting parameters such as input voltage, current, luminous flux, and power factor of street lamps for road lighting in Xingtai City, and calculating the Energy Efficiency Index (EEI) to determine the energy efficiency grade of the luminaires, we can clarify the lighting demands of road lighting in Xingtai City, providing data support for manufacturers to optimize luminaire design schemes and improving the energy-saving performance and service life of the luminaires.

1. Data Source: Before factory shipment, randomly sample finished street lamps intended for road lighting in Xingtai City, and collect their parameters including input voltage, current, luminous flux, and power factor.

2. Data Processing
(1) Conduct energy efficiency grade EEI analysis based on the collected parameters: EEI = (V×I×PF)/Pref; where PF is the power correction factor, Pref is the reference power of the luminaire, and Φ_use is the effective luminous flux of the luminaire.
Specifically:
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) Determine the energy efficiency grade according to EEI:
If EEI ≤ 0.11: Grade A++;
If 0.11 ≤ EEI ≤ 0.17: Grade A+;
If 0.17 ≤ EEI ≤ 0.24: Grade A;
If 0.24 ≤ EEI ≤ 0.6: Grade B;
If 0.6 ≤ EEI ≤ 0.8: Grade C;
If 0.8 ≤ EEI ≤ 0.95: Grade D;
If EEI > 0.95: Grade E.

3. Data Application: The Energy Efficiency Index (EEI) is one of the important indicators for evaluating luminaire energy efficiency. Conducting energy efficiency analysis before factory shipment can meet the lighting requirements of road lighting scenarios in Xingtai City. Meanwhile, it can also provide data support for manufacturers to optimize luminaire design schemes, thereby improving the energy-saving performance and service life of the luminaires.
