Different application scenarios have distinct lighting requirements for luminaires, including requirements for luminaire energy efficiency grades. By collecting parameters such as input voltage, current, luminous flux, and power factor of floodlights designated for Icelandic factories to calculate the Energy Efficiency Index (EEI), and thus determining the energy efficiency grade of the luminaires, the lighting demands in Icelandic factory scenarios can be clarified, providing data support for manufacturers to optimize luminaire design schemes and enhancing the energy-saving performance and service life of the luminaires.
1. Data Source: Before the luminaires leave the factory, randomly sample finished floodlights intended for Icelandic factories, and collect parameters including their input voltage, current, luminous flux, and power factor.
2. Data Processing
(1) Conduct energy efficiency grade analysis for the luminaires based on the collected parameters: EEI = IV * PF / Pref; where PF is the power correction factor, Pref is the reference power of the luminaire, and Фuse is the effective luminous flux of the luminaire.
When Фuse < 1300 lm: Pref = 0.88 × √Фuse + 0.049 × Фuse;
When Фuse ≥ 1300 lm: Pref = 0.07341 × Фuse.
(2) Grade classification rules: If EEI ≤ 0.11, the grade is A++; if 0.11 ≤ EEI ≤ 0.17, the grade is A+; if 0.17 ≤ EEI ≤ 0.24, the grade is A; if 0.24 ≤ EEI ≤ 0.6, the grade is B; if 0.6 ≤ EEI ≤ 0.8, the grade is C; if 0.8 ≤ EEI ≤ 0.95, the grade is D; if EEI > 0.95, the grade is E.
3. Data Application: The energy efficiency index is one of the important indicators for evaluating luminaire energy efficiency. Conduct EEI analysis before the luminaires leave the factory to meet the lighting requirements in the application scenarios of Icelandic factories; 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.
