Temperature Coefficient Measurement of LED Filament Standard Lamp

National Institute of Metrology, Beijing 100029, China

摘要

摘要: 中国计量科学研究院（NIM）自主研制了LED灯丝标准灯。温度是影响LED灯丝灯量值的主要因素，研究分析LED灯丝灯特性需准确测量其温度系数。简述了LED温度系数的定义和测量原理，讨论了NIM的LED的温度系数测量装置。实验测量LED灯丝灯，分析灯电压、灯光通量值与参考点温度的关系。使用最小二乘法拟合出灯光度量值与参考点温度，以及灯电压与参考点温度的线性表达式，依次计算出光度值温度系数和灯电压温度系数。实验数据显示，所研制的LED灯丝灯的光度值温度系数是0.17%/℃，电压温度系数是−0.025 V/℃。

Abstract: National Institute of Metrology (NIM) has independently developed LED filament standard lamp. Temperature is the main factor affecting the measurement value of LED filament lamps, and the accurate measurement of the temperature coefficient is required to study and analyze the characteristics of LED filament lamps. This paper introduces the definition and measurement principle of LED temperature coefficient, as well as NIM’s facility to implement the measurement. Experimental measurements of LED filament lamps are performed to analyze the relationship between lamp voltage, total luminous flux value and reference point temperature. The linear expressions of the total luminous flux value versus the reference point temperature and the lamp voltage versus the reference point temperature are fitted using the least squares method, and the temperature coefficients of the luminosity value and the lamp voltage are calculated sequentially. The experimental data show that the developed LED filament lamp has a photometric temperature coefficient of 0.17%/°C and a voltage temperature coefficient of −0.025 V/°C.
