用于瓦伦西亚道路照明的路灯EEI分析数据

在灯具出厂前，采集用于瓦伦西亚道路照明的路灯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，随机抽取用于瓦伦西亚道路照明的路灯的成品，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，以适配瓦伦西亚道路照明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。

Prior to factory shipment of luminaires, the Energy Efficiency Index (EEI) of street lamps intended for road lighting in Valencia is collected to determine the energy efficiency rating of the luminaires, adapt to the lighting requirements of this specific scenario, guide the optimized design of the luminaires, and improve their energy-saving performance and service life.

1. Data Source:
Prior to factory shipment, finished street lamps intended for road lighting in Valencia are randomly sampled, and parameters including input voltage, current, luminous flux, and power factor are collected for these lamps.

2. Data Processing
(1) EEI analysis for luminaires based on the 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 lamp, and Φuse is the effective luminous flux of the lamp.
When Φuse < 1300 lm: Pref = 0.88√Φuse + 0.049 Φuse
When Φuse ≥ 1300 lm: Pref = 0.07341Φuse

(2) Energy efficiency rating classification:
If EEI ≤ 0.11, the rating is A++; if 0.11 ≤ EEI ≤ 0.17, the rating is A+; if 0.17 ≤ EEI ≤ 0.24, the rating is A; if 0.24 ≤ EEI ≤ 0.6, the rating is B; if 0.6 ≤ EEI ≤ 0.8, the rating is C; if 0.8 ≤ EEI ≤ 0.95, the rating is D; if EEI > 0.95, the rating is E.

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