Abstract
Development and application of LED in situ measurement and binning system are proposed and demonstrated. In this system, the photometric and colorimetric properties of LED can be measured in a matter of milliseconds, and the measured LED can be binned to a specific bin based on color, intensity, and forward voltage. An algorithm is designed to deal with the determination of dominant wavelength of LED with a resolution of 0.1nm. The described technique can bin LEDs into groupings of uniform and reproducible parameter, and improve color consistency.
