摘要

与LED测量紧密相关的测量不确定度具有非常重要的意义。通过选择恰当的数量、装置等,可以举例分析不确定度计算的过程。试验中采用可溯源至NIM的光谱光度计和标准LED,通过实验和计算分析了LED光谱辐射强度的测量不确定度。

Abstract

Uncertainties associated with measurements of LEDs are extremely important.By choosing specific quantities,devices under test and equipments, the process of uncertainty budgets by example can be analyzed.Spectroradiometer measurements are traceable to NIM spectral irradiance scale.The particular LED was chosen because it also has an independent NIM traceable calibration via another path and can provide verification of measurements.The uncertainty of spectral radiant intensity measurements of LEDs is analyzed through experiment and calculation.
