Measurement of Luminous Flux of Blue LEDs Using Spectral-Correction-Integral-Photometry Method
-
Abstract
A spectral-correction-integral-photometry method and its application in the measurement of the luminous flux of blue LEDs are introduced.The sources of uncertainty in the measurements are theoretically analyzed.Compared to the uncertainties of the spectrophotometry method and the integral method,the results show that this method can achieve high measurement accuracy.It is important to the assessment of the LEDs’ qualities.-
