Abstract
The uncertainties in color measurements of LEDs by spectroradiometers can be much larger than those for traditional broadband sources due to the quasi-monochromatic nature of LED spectra. In this paper, the uncertainties in chromaticity of LEDS due to bandpass, scanning intervals, and wavelength errors, are analyzed by simulation. Based on the analysis, a spectroradiometer for colorimetry of LEDs has been designed and built at NIST and characterized for uncertainties in measured chromaticity coordinates and other color quantities.Conference Dates
