用于沈阳动车段的工厂灯EEI分析数据

在灯具出厂前，采集用于沈阳动车段的工厂灯的性能参数，分析该类型灯具的能效指数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，随机抽取用于沈阳动车段的工厂灯的成品，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，以适配沈阳动车段的工厂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。

Before factory lighting fixtures for Shenyang EMU Depot leave the factory, their performance parameters are collected, and the Energy Efficiency Index (EEI) of this type of fixtures is analyzed to determine their energy efficiency grades, so as to meet the lighting requirements of this specific scenario and guide the optimized design of the fixtures, thereby improving their energy-saving performance and service life.
1. Data Source: Before leaving the factory, finished factory lighting fixtures for Shenyang EMU Depot are randomly sampled, and parameters such as input voltage, current, luminous flux and power factor of the fixtures are collected.
2. Data Processing
(1) Conduct energy efficiency grade EEI analysis for the fixtures based on the collected parameters:
EEI=P*PF/Pref=IV*PF/Pref;
Where P is the rated power of the fixture, 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) The energy efficiency grade is divided as follows:
If EEI ≤ 0.11: Grade A++; If 0.11 ≤ EEI ≤ 0.17: Grade A+; If 0.17 ≤ EEI ≤ 0.24: Grade A; If 0.24 ≤ EEI ≤ 0.6: Grade B; If 0.6 ≤ EEI ≤ 0.8: Grade C; If 0.8 ≤ EEI ≤ 0.95: Grade D; If EEI > 0.95: Grade E.
3. Data Application
The Energy Efficiency Index is one of the important indicators for evaluating the energy efficiency of lighting fixtures. Conducting EEI analysis before the fixtures leave the factory can meet the lighting requirements of the application scenario of factory lighting fixtures in Shenyang EMU Depot. Meanwhile, it can also provide data support for manufacturers to optimize the fixture design scheme, thereby improving the energy-saving performance and service life of the fixtures.
