Spectroradiometer requirements for LED Binning
Despite the most sophisticated manufacturing technologies employed by the semiconductor industry, light output and colour temperature of LEDs varies from chip to chip. Therefore, binning is employed to maximise yields and to categorise products. Standards such as ANSI C78.377-2017  define tolerance bands or ‘bins’ with respect to chromaticity boundaries. Therefore, without exception, LED binning requires the absolute spectral power distribution of devices to be measured in order to precisely determine the light output and the correlated colour temperature (CCT) of each individual LED. Light output is most commonly measured in terms of luminous flux (lm) although Averaged LED Intensity  is also sometimes specified.
Quality control of LED spotlight manufacturing processes with a single measuring device
The development and manufacture of good quality LED spotlights requires an extensive range of photometric and colorimetric measurements. The investment required for equipping and operating a comprehensive photometric test laboratory can seem prohibitive for the many medium-sized manufacturers offering products in this marketplace. Therefore, the possibility of a universally applicable and compact measuring device for the various measurement tasks is attractive.
