Different application scenarios have distinct lighting requirements for luminaires, including requirements for their energy efficiency grades. This dataset collects parameters including input voltage, current, luminous flux, and power factor of street lamps designated for the Hangzhou West Lake District, to calculate the Energy Efficiency Index (EEI) and determine the luminaires' energy efficiency grades. This helps clarify the lighting demands for this area and provides data support for manufacturers to optimize luminaire design schemes, enhancing the energy-saving performance and service life of luminaires. 1. Data Source: Finished street lamps intended for the Hangzhou West Lake District are randomly sampled before leaving the factory, and their input voltage, current, luminous flux, power factor and other related parameters are collected. 2. Data Processing (1) Energy efficiency grade (EEI) analysis for luminaires based on the collected parameters: The calculation formula for EEI is: EEI = (V × I × PF) / Pref, where PF refers to the power correction factor, Pref is the reference power of the luminaire, and Φ_use represents the effective luminous flux of the luminaire. The calculation method for Pref varies according to the value of Φ_use: 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 grade classification based on EEI: Grade A++: EEI ≤ 0.11; Grade A+: 0.11 ≤ EEI ≤ 0.17; Grade A: 0.17 ≤ EEI ≤ 0.24; Grade B: 0.24 ≤ EEI ≤ 0.6; Grade C: 0.6 ≤ EEI ≤ 0.8; Grade D: 0.8 ≤ EEI ≤ 0.95; Grade E: EEI > 0.95. 3. Data Application: The energy efficiency index is one of the critical indicators for evaluating luminaire energy efficiency. Conducting EEI analysis on luminaires before they leave the factory enables them to meet the lighting requirements of the Hangzhou West Lake District scenario. Meanwhile, this dataset provides data support for manufacturers to optimize luminaire design schemes, improving the energy-saving performance and service life of luminaires.
