收藏资源简介：
在灯具出厂前，采集用于常熟市的路灯EEI，从而确定灯具的能效等级，以适用于该特定场景下的照明需求，指导灯具优化设计方案，提高灯具的节能性能和使用寿命。1.数据来源：在灯具出厂前，随机抽取用于常熟市的路灯的成品，采集该路灯输入电压、电流、光通量和功率因子等参数。 2.数据处理 (1)基于采集的参数对灯具进行能效等级EEI分析： EEI=P*PF/Pref=IV*PF/Pref； 其中P是灯具的额定功率，PF是功率修正因子；Pref是灯的参考功率，Φuse为灯的有效光通量。 当Φuse<1300lm时：Pref =0.88√Φuse +0.049 Φuse 当Φuse≥1300lm时：Pref =0.07341Φuse (2)若EEI≤0.11，为A++级；0.11≤EEI≤0.17，为A+级；0.17≤EEI≤0.24，为A级；0.24≤EEI≤0.6，为B级；0.6≤EEI≤0.8，为C级；0.8≤EEI≤0.95，为D级；EEI>0.95，为E级。 3.数据应用： 能效指数是评估灯具能效的重要指标之一，灯具出厂前进行等效分析，以适配常熟市的路灯应用场景下的照明需求；同时也可为厂商优化灯具设计方案提供数据支撑，提高灯具的节能性能和使用寿命。
This dataset collects the Energy Efficiency Index (EEI) of streetlights intended for Changshu City before factory shipment, to determine the energy efficiency grades of luminaires, adapt to the lighting requirements of this specific scenario, guide the optimization of luminaire design schemes, and improve the energy-saving performance and service life of luminaires. 1. Data Source: Before factory shipment, finished streetlight luminaires for Changshu City are randomly sampled, and parameters such as input voltage, electric current, luminous flux and power factor of these streetlights are collected. 2. Data Processing (1) Energy Efficiency Index (EEI) analysis for luminaires based on collected parameters: EEI = P*PF/Pref = IV*PF/Pref; where P is the rated power of the luminaire, 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 + 0.049Φ_use; When Φ_use ≥ 1300 lm: Pref = 0.07341Φ_use. (2) Energy efficiency grade 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 (EEI) is one of the important indicators for evaluating luminaire energy efficiency. Conducting EEI-based analysis on luminaires before factory shipment can meet the lighting requirements of the streetlight application scenario in Changshu City; meanwhile, it can also provide data support for manufacturers to optimize luminaire design schemes, improving the energy-saving performance and service life of luminaires.
