测量350～1100nm光源光谱总辐射通量的标准装置
The Standard Measurement Facility for Total Spectral Radiant Flux Measurement of 350～1100nm Light Source
摘要
Abstract
To meet the increasing demand for total spectral radiant flux (TSRF) measurement in the LED industry, we developed a facility of an integrating sphere with a spectroradiometer, and developed relative standard operational procedure. The facility can quickly transfer the TSRF quantity from the standard lamp to the testing lamp. The basic concept, standard operational procedure and measurement uncertainty analysis are shown. The TSRF expanded uncertainty at wavelength range 350～1 100 nm is Urel=3.1％～1.3％ (k=2). A group of TSRF standard lamp, calibrated by the goniospectroradiometer, are tested using this facility. The experimental results showed the consistency deviations of the group of standard lamp were small than 0.8％ at the wavelength range of 350～1 100 nm.关键词
