This dataset is generated by collecting data of floodlights for Sichuan-Lijiang Panzhihua Expressway tunnels prior to their factory shipment, aiming to determine the energy efficiency grades of the luminaires, meet the lighting requirements of this specific scenario, guide the optimization of luminaire design schemes, and enhance the energy-saving performance and service life of the luminaires.

1. Data Source
Prior to factory shipment, finished floodlight products designated for Sichuan-Lijiang Panzhihua Expressway tunnels are randomly sampled, and parameters including input voltage, current, luminous flux, and power factor of the luminaires are collected.

2. Data Processing
(1) Energy efficiency index (EEI) analysis is conducted for the sampled luminaires based on the collected parameters, with the following formula:
EEI = P × PF / Pref = (I × V) × PF / Pref
Where P denotes the rated power of the luminaire, PF is the power factor, Pref represents the reference power of the luminaire, and Φ_use is the effective luminous flux of the luminaire.
The reference power Pref is calculated using distinct formulas based on the value of Φ_use:
- When Φ_use < 1300 lm: Pref = 0.88√Φ_use + 0.049Φ_use
- When Φ_use ≥ 1300 lm: Pref = 0.07341Φ_use
(2) The energy efficiency grade is classified as follows based on the EEI value:
- A++ grade: EEI ≤ 0.11
- A+ grade: 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 key indicators for evaluating luminaire energy efficiency. Conducting energy efficiency analysis prior to factory shipment can adapt the luminaires to the lighting demands of the Sichuan-Lijiang Panzhihua Expressway tunnel floodlight application scenario. Moreover, it can provide data support for manufacturers to optimize their luminaire design schemes, thereby improving the energy-saving performance and service life of the luminaires.
