用于浙江省杭州市环城北路的路灯EEI分析数据

在灯具出厂前，采集用于浙江省杭州市环城北路的路灯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，随机抽取用于浙江省杭州市环城北路的路灯的成品，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，以适配浙江省杭州市环城北路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 EEI (Energy Efficiency Index) of street lamps designated for Huancheng North Road, Hangzhou, Zhejiang Province prior to their factory shipment, to determine their energy efficiency grades, meet the lighting demands of this specific application scenario, guide the optimized design of the lamps, and enhance their energy-saving performance and service life.

1. Data Source: Randomly sample finished street lamps designated for Huancheng North Road, Hangzhou, Zhejiang Province prior to their factory dispatch, and collect parameters such as input voltage, current, luminous flux, and power correction factor of these street lamps.

2. Data Processing
(1) EEI-based energy efficiency grade analysis for the sampled lamps using the collected parameters:
EEI = P × PF / Pref = IV × PF / Pref;
Where P is the rated power of the lamp, PF is the power correction 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 grade classification:
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 core indicators for evaluating lamp energy efficiency. Conducting corresponding analysis prior to factory shipment helps adapt to the lighting requirements of the street lamp application scenario on Huancheng North Road, Hangzhou, Zhejiang Province. Meanwhile, it can also provide data support for manufacturers to optimize lamp design schemes, improving the energy-saving performance and service life of the lamps.
